Operating instructions for hisense split system. Instructions for use. Additional coating of the heat exchanger GOLDEN FIN

The Chinese industrial group Hisense is the world's largest manufacturer of household and industrial appliances. The company produces duct air conditioners, premium models, and Hisense household multi-split systems. The products of this brand appeared on the Russian market in the early 2000s and won the trust of buyers with quality, range and affordable prices.

NEO Premium Classic A Series

The flagship of the company can be considered the Neo Premium classic A line of air conditioners. This is the second generation of models without an inverter, characterized by good technical and operational qualities. To optimize costs, a system for reducing energy consumption was developed; almost all functions are fully automated.

View indoor unit classic, with rounded edges. The digital LED indicator is located behind translucent plastic, which does not interfere with reading the readings. The Neo Premium classic A series differs from standard budget models in the soundproofing of the outdoor unit - it operates much quieter than conventional air conditioners.

Features of Hisense Neo Classic A:

fully automatic blinds with the ability to remotely adjust their position;
the Toshiba compressor, which ensures proper refrigerant compression, produces minimal noise during operation;
a complete set of filter elements model neo.

In fact, the classic is a type of budget air conditioner, but the multi-split system has good performance indicators, ease of maintenance and intuitive settings. In the photo, the design of the indoor unit is close to the standard one, which makes it possible to fit it into any interior of the living room.

The user must clean the installed air filters himself. To do this, you need to remove the front panel of the indoor unit, after first turning off the power to the Hisense wall-mounted air conditioner.

Smart DC Inverter Series

For greater energy savings and improved performance, the company has developed inverter air conditioner Hisense Smart DC Inverter. The models have an expanded range of power parameters - from 7K to 24K. Systems for intelligent adjustment of current indicators are also used.

The design of the internal unit of the Hisense split system has remained recognizable, the design of the components and their functionality have changed. The buyer can choose only one color - white. The compressor of the outdoor unit is Japanese - Toshiba. Unlike ducted air conditioners, models can serve only one room.

Advantages of the Hisense Smart DC Inverter multi split system:

the optimal cooling performance step of the Hisense air conditioner is 0.5 kW;
Hisense inverter split systems have improved air filtration;
the “Smart” function will allow you to configure the operating mode at the user’s location;
changing the position of the blinds in the horizontal and vertical plane.

Another advantage is the price - Hisense air conditioners in this series cost from 21,000 rubles. When choosing, it is important to pay attention to the first two characters - vrv or vrf indicate the absence of an inverter system. Intelligent and energy-saving air conditioning systems are designated by the letters AS.

To set up the Hisense multi-split system, you need to read the recommendations from the manufacturer. There should be no obstacles in the path of the air flow; the angle of rotation of the blinds is additionally taken into account.

Review of additional episodes

To increase the range, the manufacturer has developed several collections that differ from those described above only in design and size. Thus, you can purchase a Hisense wall-mounted air conditioner with a minimum thickness of the internal unit, which is important for small rooms. A duct air conditioner or its more powerful analogues - Hisense column air conditioners - do not have such variety.

The difference between the models lies in appearance, the absence or presence of additional functions. Choice similar systems is relevant if the design of the Hisense AS air conditioner is not suitable for the interior of the room. For this, the company has developed several series that differ not only in shape, but also in color.

The most interesting models:

Hisense Premium FUTURE Design DC Inverter Wall Mounted Air Conditioner. It is distinguished by the rounded shape of the indoor unit body and elegant colored inserts along its edges. The Mirage display does not highlight when turned off.
BLACK Star DC Inverter. The shape is completely identical to the Smart DC series, with the exception of the body color, which is made black. Functions and specifications remained the same.
Premium SLIM Design Super DC Inverter. The thickness of the case is 11.3 cm. At the same time, the maximum set of options has been preserved. The block color is cream. It is also possible to operate under significant voltage fluctuations. The minimum value is 175 V.

The table shows the main characteristics of Hisens inverter and simple models.

Instructions for the control panel and Hisense air conditioners

To control the operation of the air conditioner, the manufacturer has developed a convenient remote control. The location of the buttons on it allows you to quickly change the current mode of the climate system; data on the liquid crystal display shows the parameter values. The only drawback is the small screen size.

For ease of operation, the user can select the following functions:

Cooling mode with set temperature value. Some models provide control of a specific zone in the room.
Possibility to choose how to configure the air conditioner - manually or automatic mode. In the latter case, the system will change the parameters itself, depending on the air temperature outside and indoors.
Detailed instructions on how to adjust the multi-split system - setting for heat, ventilation or cooling.

It should be remembered that to reset the settings, it is not enough to simply turn off and then turn on the remote control - they are saved automatically.

When servicing your air conditioner, it is important to know what type of refrigerant needs to be put into the system. Most models are compatible with R410A freon. It must not be mixed with other refrigerants as this may cause damage.

Hisense air conditioner error codes

If the air conditioning system is installed and maintained correctly, the likelihood of it breaking is low. It will work for both cooling and heating. The main advantage of air conditioners of this brand is their reliability. But, like any other equipment, climate control equipment can fail and malfunction.

Below you can find instructions for maintenance and self-removal of minor defects.

It is prohibited to carry out any type of repair if the following faults are present:

a sharp decrease in productivity;
the appearance of an excessively large amount of condensation on the indoor unit;
increase in noise;
fan failure;
loss of pipeline tightness.

You can preview the error codes for the indoor unit. If faults occur, they will be displayed on the display or remote control remote control.

To display error codes on the display, press the “Sleep” button 10 times. This feature is not available on older models.

PREPARATION FOR USE

Before using the air conditioner, be sure to check and preset as follows.

 Pre-setting the control panel

The remote control may not be preset at the factory.

If you find flashing indicators on the display even after power is supplied to the control panel, then you need to select the mode for the remote control yourself.

 Pressing any of the buttons while the indicator is flashing will preset the remote control for heating-drying mode.

 Pressing any of the buttons while the indicator is flashing will preset the remote control for cooling mode only.

The absence of flashing indicators will indicate that the control panel has a preliminary automatic tuning to heating-drying mode.

Note:

If the air conditioner you purchased has only a cooling mode, and the remote control is preset to the heating-drying mode, this is not of fundamental importance.

But if you purchased an air conditioner with a heating-drying mode, and the remote control is preset to the cooling mode, then the heating function will be lost. You will need to pre-set the remote control for heating-drying mode.

 Backlight function (optional)

Hold down any of the buttons on the remote control for about 2 seconds to turn on the backlight. The backlight turns off automatically after approximately 10 seconds.

Note: Backlight is an optional (additional) feature.

 Pre-setting automatic restart

The air conditioner has an automatic restart function. You can set or cancel this function while the air conditioner is operating.

 Hold down the emergency button (ON/OFF) for several seconds. This function will be set after 2 beeps. If you heard 1 sound signal, then this function will be cancelled.

4D AUTO Air

HISENSE's new technology for indoor air distribution gives the user maximum comfort.

Automatic horizontal and vertical blinds allow you to choose any of 4 convenient this moment modes:
. The simultaneous automatic operation of these blinds allows you to cool the room most evenly, creating the effect of constant air movement, without the appearance of a draft inside the room.
. The fixed position of horizontal blinds with automatic operation of vertical blinds allows you to direct the air flow left and right in a given horizontal plane.
. The fixed position of vertical blinds with automatic operation of horizontal blinds allows you to direct the air flow up and down in a given vertical plane.
. The constant position of horizontal and vertical blinds allows for spot cooling.

MIRAGE display

The front panel of all wall-mounted split systems is made of translucent plastic, thanks to which the company's HISENSE - MIRAGE display is implemented, which remains completely invisible if the air conditioner is turned off.

Smart Mode - Smart Mode

A convenient mode for cases of sudden temperature changes outside during the day, or for users who do not want to think about choosing the operating mode of the air conditioner. It is enough to select the desired room temperature and SMART mode, and a special free logic algorithm will automatically determine the operating mode of the air conditioner and best settings fan mode.

IFEEL function

The HISENSE remote control is equipped with a temperature sensor, thanks to which it is possible to more accurately maintain the temperature in the room, directly at the location of people.

Energy efficiency

The energy efficiency of equipment is becoming an increasingly important indicator every year. If earlier high values of this indicator indicated the quality of the equipment and a high technological level, now, with an increase in electricity tariffs, energy efficiency becomes an important economic factor when making a purchase decision, since it directly affects the additional costs associated with the operation of the air conditioner. IN currently V different countries There are several classifications of energy efficiency of split-type air conditioning systems (split systems).

Russian classification of energy efficiency of air conditioners

The classification currently used in Russia is similar to the European one, which was used before January 1, 2013. Russian system the classification is quite simple and understandable - it takes into account the direct ratio of the generated cooling or heating power to the consumed electricity when operating in nominal mode. For cooling and heating modes, the values of this coefficient are different. To determine the energy efficiency class in cooling mode, you need to take the rated cooling power, divide it by the rated energy consumption in cooling mode, correlate the resulting value with the table and understand which class the air conditioner belongs to. This indicator is called EER - Energy Efficiency Ratio - System energy efficiency coefficient in cooling mode. A similar calculation is made for the heating mode. The coefficient showing the efficiency in heating mode is called COP - Coefficient of Performance - performance coefficient in heating mode. All equipment, in accordance with the rules, must be marked with a clear color sticker indicating the class.

European Union air conditioner energy efficiency classification

In Europe, since January 1, 2013, a complex system for determining the energy efficiency of air conditioners has been adopted. Her technique is based on the fact that the air conditioner does not always operate in nominal mode, that is, at full load. Most of the time, the air conditioner operates at partial load, which means the ratio of the cold (or heat) produced does not correspond to the nominal values. This technique has the greatest practical meaning for air conditioners that use inverter control technology, that is, air conditioners that can smoothly change their power, adapting to the required partial load. It involves measuring the ratio of produced cold (heat) to the corresponding energy consumption at 4 different loads. After this, weighting coefficients are applied to the obtained values, indicating the frequency of operation of the air conditioner in this mode, then the obtained values are summed up. Since air temperatures differ throughout the year in different climatic zones, different weighting coefficients were introduced for different territories.

The European Union was divided into 3 climate zones, with similar temperatures throughout the year.

A new technique shows the seasonal energy efficiency of an air conditioner.

For cooling mode, this is the SEER indicator - Seasonal Energy Efficiency Ratio - the seasonal energy efficiency coefficient of the system in cooling mode. For heating mode, this is the SCOP indicator - Seasonal Coefficient of Performance - the seasonal coefficient of system performance in heating mode.

It is necessary to understand that the methodology does not directly show the ratio of electricity consumed and output power, but serves to correlate different air conditioners with each other. In addition, measurements of these indicators must be carried out by certified laboratories, since they cannot be directly verified by consumers.

Low Noise - Quiet Mode

The design of the indoor unit has been optimized, including:
. new design of fan impeller of increased diameter with new form shoulder blades,
. low noise engines,
. a specially developed aerodynamic solution for the entire air channel, starting from the air intake grille, continuing through the heat exchanger with an improved design, the shape of the air distribution nozzle and a special shape of the blinds.

All this made it possible to reduce the noise level of the indoor unit to extremely low values, amounting to 22 dB(A) for premium models in low noise mode.

ULTRA Hi Density Filter

ULTRA Hi Density filter is a new generation high purity filter. Compared to a regular dust filter, a high purification filter removes more than 90% of dust and other particles from indoor air. The filter is simply cleaned of contaminants under running water.

Additional filters

LTC filter
LTC filter or formaldehyde filter removes harmful organic compounds from the room.

Carbon filter
Since carbon is an excellent absorbent, this type of filter effectively absorbs odors and many types of chemicals.

Photocatalytic filter
Filters of this type are able to effectively oxidize and destroy molecules of chemical compounds, odors, as well as viruses, bacteria, fungal spores and other pollutants of organic origin. The filter can be quickly restored by keeping it in the sun for 6-8 hours after 3-4 months of use.

Silver Ion filter
Air flow passing through this filter, is purified with silver ions, which can prevent the appearance of germs and bacteria. In addition, the remaining silver ions are carried by the air flow into the room, trap small dust particles, thereby continuing to disinfect the air.

HEPA filter
The HEPA filter is a super high-purity filter because it effectively traps the smallest elements of dust, allergens, pollen and a number of others.

Negative Ion Filter
The Negative Ion filter produces negatively charged ions, which, in addition to having a positive effect on the body, are actively involved in the process of air purification. They transfer a charge to dust particles, which begin to attract each other and form larger particles, increasing the efficiency of air purification.

Protective cover for external unit valves

Hisense split systems are supplied with a protective cover on the valves of the external unit. This prevents precipitation from affecting critical connections and increases operational reliability.

Self-cleaning function

A special algorithm for the operation of the air conditioner after turning it off leaves the fan of the indoor unit in working condition for some time. This allows you to dry the heat exchanger from condensation that forms during operation.

Modern self-adaptive technology for controlling BLDC compressor electric motors

Modern self-adaptive BLDC control technology for compressor electric motors helps air conditioners run quieter and more efficiently.

Combination of BLDC motor (brushless motor direct current) with new control algorithms allow you to achieve:
. low noise level
. high performance
. higher level of stability and service life

Intelligent PFC control technology

PFC control technology can maintain the required voltage when necessary to compensate in case of low voltage in the network.

The air conditioning control system automatically turns on or off this function.

The PFC operates according to current voltage conditions to ensure operation continues to be as efficient as possible when voltage is unstable.

The operating voltage range becomes increased and may differ from the nominal voltage by 20%.

Starting and torque compensation technology at low frequencies

According to the load characteristic curve of the compressor, HISENSE has developed low frequency torque compensation technology.

This technology improves the stability of the compressor at low frequency, reduces vibration of the compressor and expands the operating range at low frequency to 10 Hz, which expands the power range of the compressor.

Nonlinear Magnetic Control Technology

The unique nonlinear magnetic control technology developed by HISENSE can work with high frequency under high load conditions, in a wider frequency range to guarantee more power cooling/heating.

FULL 3-DC INVERTER technology (Super DC Inverter HISENSE)

HISENSE Premium DC Inverter air conditioning systems use FULL 3-DC INVERTER technology.

It includes not only the use of a DC INVERTER compressor for maximum efficiency, but also all components manufactured using DC INVERTER technology.

First of all, these are the fan motors of external and internal units. Fully inverter control of all elements of the air conditioner allows not only to create the most quiet and comfortable air conditioner, but also to make it as energy efficient as possible, which is confirmed by the European seasonal energy efficiency class A++.

Standby consumption 1W - 1W Standby

Thanks to improvements in the design of the power supply, it has become possible to reduce power consumption in standby mode to a uniquely low value - only 1 W. This means that when the air conditioner is turned off, it actually does not consume electricity to maintain itself in standby mode and to power the memory unit where it stores latest settings.

Accurate room temperature maintenance

HISENSE class Super DC Inverter and DC Inverter air conditioners give the user new level comfort.

The combination of all inverter power control technologies, the I FEEL function and HISENSE's special developments in the field of inverter control has made temperature maintenance even more accurate, even compared to conventional Inverter systems. This ensures that the temperature is maintained as accurately as possible according to the value set on the remote control.

Cold Plasma Ion Generator - Plasma air purification

Plasma air purification kills viruses and neutralizes toxic substances, prevents the spread of infectious diseases, removes dust and unpleasant odors and creates the effect of fresh forest air in the room.

Sleep mode - sleep mode

HISENSE brings innovation to the Sleep Mode that has become familiar to air conditioning systems. The user is offered a choice of 4 different modes, each of which is characterized by different preset parameters.

We are talking about various automatic settings for maintaining temperature, allowing you to choose the most comfortable mode for different ages, for each specific person.

Intelligent defrosting system for the external unit Smart Defrost

In winter, when heating is operating, ice forms on the heat exchanger of the external unit.

To continue operation of the system, it is necessary to carry out a defrosting procedure to normalize further operation.

As a standard, this issue is resolved by turning on the timer defrost mode, which leads to a stop normal operation air conditioner even in cases where ice has not yet formed.

The intelligent Smart Defrost algorithm developed by HISENSE operates only when necessary, reducing energy consumption by eliminating unnecessary defrosting processes. This brings additional comfort during heating mode and reduces defrosting time.

Indoor unit fan

New development of HISENSE - asymmetric tangential fan. During its development, the latest achievements were used not only in theoretical, but also in experimental aerodynamics, which made it possible to create a fan that is truly outstanding in its characteristics. Increased fan performance made it possible to reduce its rotation speed, which led to a decrease in noise from the engine, which began to rotate at slower speeds. At the same time, the air flow has become more powerful and quieter.

Outdoor unit fan

The design efficiency of an outdoor unit fan is no less important than that of an indoor unit fan. Although the consumer does not notice its operation, it is the design of the external unit fan that is largely responsible for the energy efficiency of the air conditioning system as a whole. HISENSE has carried out special developments in this area. This made it possible to create a fan of a new, most aerodynamically efficient design.

Protection of components in the indoor unit

Protective metal box for electrical components in the indoor unit

International safety standard. Each air conditioner undergoes 52 inspection tests according to American regulations, including IEC test, to ensure high safety standards.

Fireproof plastic and connector

For the Super DC series and the Premium Classic A HISENSE series, fire-resistant, safe plastic materials are used. In the event of a fire, these plastic materials will prevent the flames from spreading.

Aluminum fins for complex profile heat exchangers

The aluminum plates used in the production of heat exchangers for HISENSE air conditioners are very different from the classic “smooth” version. They have a complex shape obtained by pressing, as well as additional specially shaped perforations. This makes the heat exchange process much more efficient compared to the traditional one. Heat exchange occurs more quickly and evenly.

Additional coating of the heat exchanger GOLDEN FIN

This technology is applied to aluminum plates of external units.

The outer layer of aluminum tends to oxidize slowly, which changes the efficiency of heat transfer over time, and also leads to faster surface contamination, which reduces heat transfer.

The GOLDEN FIN protective coating is a nanolayer of a special yellow plastic compound (hence its name), which gives the heat exchanger several additional properties.

It blocks the oxidation process, preserving the aluminum surface. The surface becomes much more “slippery”, so surface contamination occurs much more slowly.

The “slippery” surface increases the efficiency of operation in the cold season in the heating mode, as the removal of condensate and the efficiency of the “defrost” mode are accelerated.

This coating makes the heat exchanger block of the external unit as resistant to aggressive environments as possible and is used, for example, for equipment supplied to coastal regions.

Using copper tubes with internal fins

In the production of heat exchangers for Hisense air conditioners, we use copper tubes special design. Unlike standard tubes with a smooth inner surface, these tubes have internal fins.

This allows you to increase the heat exchange area and create an additional turbulence effect inside the tubes, which in total significantly increases operating efficiency.

This allows the use of smaller diameter tubes, which reduces the amount of refrigerant found in the air conditioner, and also allows for more compact units without losing energy efficiency.
