What are the parts of the wall mounted indoor air conditioner enclosure?

Wall-mounted air conditioners are also household air conditioners that people often see, also known as wall-mounted split air conditioners. Although the wall-mounted air conditioner looks very simple, there are only two indoor units and outdoor units, but its internal structure is also very complex. So what is the external structure of the wall-mounted air conditioner?

01 The indoor unit of the hanging type with the air conditioner is mainly composed of a heat exchanger, a cross-flow fan and an electric motor, an automatic wind direction system, a drainage system, etc. Talk about the difference.

02 In indoor units, the function of heat exchanger is mainly used to cool or heat indoor air. The fan and the motor are to form a circulating state of indoor air, for the previous air conditioning fan, now the wall air conditioner through the fan has increased a lot of blades, the speed is low, can ensure that the noise decibel is reduced to a minimum, will not affect people's lives.

03 The role of the drainage system is even more powerful, when the air conditioner is in the process of refrigeration, the heat exchanger will produce condensate, and this condensate needs to be discharged to the outside through the drainage system.

02 The outdoor unit capacity of the air conditioner is relatively small, and it also needs to be equipped with so many leaky components, so the outdoor unit is generally a single fan to solve the problem of heat dissipation, unlike a large cabinet air conditioner, which must be equipped with two fans to increase the amount of air circulation. In addition, the four-way reversing valve inside the outdoor unit is mainly for vacuuming and adding refrigerant, and the compressor works to compress the refrigerant into liquid, and then enters the indoor heat exchanger through the pipeline to complete the task of cooling and heating.

03 There are two valves on the side pipeline of the outdoor unit, one is the connection between the two-way valve and the liquid pipe (a thin one) of the indoor unit, and the other is the connection between the three-way valve and the air pipe (a thick one) of the indoor unit, and there is a maintenance port in the three-way valve that can be used to vacuum and add refrigerant.

04 Since the cooling capacity of split wall-mounted household air conditioners is generally between 1860 and 4300W, and the capacity is small, the outdoor units are all single fan types. For split air conditioners with large cooling capacity, such as cabinet air conditioners, the air circulation system of the outdoor unit generally adopts the form of dual fans to increase the air circulation volume.

Air conditioner is a kind of equipment used to adjust air temperature, humidity, flow rate and cleanliness, which is mainly composed of four major components: compressor, condenser, throttling device and evaporator.

Split air conditioner is a common type of air conditioner, which divides the air conditioner into two parts: indoor unit and outdoor unit, which are connected by pipes and wires to form a cooling (heating) circulation system.

The main components of the indoor unit of the air conditioner are as follows:

Evaporator: It is a finned copper-aluminum heat exchanger, which is used to absorb the heat in the chamber and make the refrigerant change from liquid to gaseous, so as to achieve the purpose of refrigeration. When heating, it acts the opposite, and is used to release heat to make the refrigerant change from gaseous to liquid, so as to achieve the purpose of heating.

Fan motor: It is an electric motor that drives the fan to rotate and is used to blow air through the evaporator, realizing the heat exchange between the air and the refrigerant, and also changing the flow rate and direction of the air.

Electronic control components: It includes a control board, a remote control, a temperature sensor, a humidity sensor, etc., which is used to receive the user's instructions, control the operating status of the air conditioner, display the working parameters of the air conditioner, and protect the safe operation of the air conditioner.

Throttling components: It includes capillary tubes or electronic expansion valves, etc., which are used to control the flow and pressure of the refrigerant from the high-pressure side to the low-pressure side, so as to achieve throttling and depressurization of the refrigerant.

Enclosure: It is a metal or plastic structure that wraps around other parts to protect the internal parts of the air conditioner, and also plays a role in aesthetic and sound insulation when judged by the same limbs.

The main components of the outdoor unit of the air conditioner are as follows:

Compressor: It is a device that sucks the refrigerant from the low-pressure side and compresses it to the high-pressure side and discharges it, which is used to increase the temperature and pressure of the refrigerant and realize the cyclic movement of the refrigerant.

Condenser: It is a positive sliding fin copper-aluminum heat exchanger, which is used to dissipate the heat of the refrigerant, so that the refrigerant changes from gaseous to liquid, so as to achieve the purpose of refrigeration. When heating, it has the opposite effect, which is used to absorb external heat, and the refrigerant is changed from liquid to gaseous, so as to achieve the purpose of heating.

Fan motor: It is an electric motor that drives the fan to rotate, which is used to blow air through the condenser, realizing the heat exchange between air and refrigerant, and also changing the air.

The part that hangs outdoors is called the outdoor unit.

The role of the outdoor unit of the air conditioner is:

The high-pressure and high-temperature gas discharged from the indoor unit is cooled and dissipated outdoors (through a fan), and the condensed refrigerant liquid is sent to the evaporator of the indoor unit through the capillary tube to evaporate into gas to absorb the heat in the indoor unit. To put it simply, the role of the refrigerant in the air conditioner in the circulation process is to absorb heat indoors and dissipate heat outdoors - after dissipating heat, it returns to the room to absorb heat.

External machine. Regardless of whether the air conditioner or the ordinary wall-mounted machine or cabinet machine is called an external unit. Outdoor unit.

Hehe, of course, the outdoor one is called an outdoor machine, talking about playing. That's called a compressor.

Summary. Good afternoon, dear, I'm honored to answer for you. Wall-mounted split air conditioner refers to the installation of the indoor unit and the outdoor unit of the air conditioner separately, and the connection of the indoor unit and the outdoor unit through the refrigerant pipeline to achieve the cooling and heating of indoor air.

Its structural characteristics mainly include the following points: 1. The indoor unit of the wall-mounted split air conditioner is installed on the wall, which saves space compared with the traditional air conditioner, and is easy to install, and does not need to destroy the wall structure. 2. The outdoor unit is usually installed outdoors or on the balcony, and the indoor unit is connected through the refrigerant pipeline to reduce the indoor noise.

3. The indoor unit is mainly composed of a casing, a motor, a wind wheel, a refrigerator, etc. The casing material is usually made of materials with excellent performance such as fireproof, moisture-proof, mildew-proof, and corrosion-resistant. The chiller uses efficient refrigeration technology to quickly reduce the indoor temperature.

4. The outdoor unit is usually composed of a compressor, a condenser, an electronic expansion valve, a fan, etc. The compressor is the core component of the air conditioning system, and the condenser is mainly responsible for dissipating the heat from the refrigerant into the outdoor air. The electronic expansion valve can automatically adjust the cooling capacity according to the temperature change in the room.

The fan can enhance the heat dissipation effect of the outdoor unit and improve the cooling efficiency of the air-conditioning system. 5. Wall-mounted split air conditioners usually have the advantages of energy saving, environmental protection, and low noise. At the same time, it can also automatically adjust the cooling capacity and heating capacity according to the changes in indoor temperature and humidity, which improves the comfort of air conditioning.

The classification of air conditioners is not difficult, and air conditioners can be divided into the following categories according to the following methods.

Classification of air conditioners.

An air conditioner is a kind of equipment that provides air conditioning and treatment for home, office and other space areas, and its main function is to adjust the temperature, humidity, purity and air flow rate in the air. Before learning about air conditioner maintenance, we need to have a clear understanding of the types and performance parameters of air conditioners. With the improvement of people's living standards, air conditioners have been installed in many occasions such as shopping malls and factories.

At present, there are various types of air conditioners on the market, and they can usually be classified according to the way they are driven, the structure and the function.

Fixed frequency air conditioners and inverter air conditioners.

Air conditioners can be divided into two types: fixed-frequency air conditioners and inverter air conditioners according to the different working frequencies of their compressors. The appearance of these two types of air conditioners is also basically the same, and usually, we can distinguish them by the identification of the air conditioner or the circuit of the outdoor unit. Figure 1-1 shows the identification of fixed-frequency air conditioners and inverter air conditioners.

Integral air conditioner and split air conditioner.

Air conditioners can be divided into two categories: integral air conditioners and split air conditioners according to their structural classification.

1) Integral air conditioner (window air conditioner).

An integral air conditioner is an air conditioner that integrates the outdoor unit with the indoor mechanism to form an independent air conditioner, such as an old-fashioned window air conditioner, as shown in Figure 1-2. Due to the high operating noise and low refrigeration efficiency of integral air conditioners, they are rarely used at present.

2) Split air conditioner.

Split air conditioner refers to the air conditioner in which the outdoor unit and the indoor unit are placed separately, and it is also one that is most used now. Common split air conditioners can be divided into three types: wall-mounted, cabinet-mounted, and ceiling-mounted, as shown in Figure 1-3. Among them, the split wall-mounted air conditioner does not occupy the use space, is easy to match with the interior decoration, has low noise, and the cooling capacity is relatively small; The split cabinet air conditioner has high power and strong wind, and is suitable for rooms with a large area, but it is noisy and needs to occupy a certain amount of space; The split ceiling air conditioner is installed on the top of the room and takes up little space, but it is troublesome to maintain and clean.

Single-cooling air conditioners and heating and cooling air conditioners.

Air conditioners are classified according to their functions, and can be divided into two categories: single cooling air conditioners and cooling and heating air conditioners according to their cooling and heating capacity.

1) Single-cooling air conditioner.

The single-cooling air conditioner is suitable for summer, can be refrigerated and dehumidified, the function is relatively simple, and its relevant parameters can be read from its nameplate logo. Figure 1-4 shows the product identification of a single-cooler air conditioner. At present, the single cooling type of air conditioner has gradually disappeared from the market.

2) Air conditioning and heating type.

Heating and cooling air conditioners can not only refrigerate and dehumidify, but also heat up when the temperature is low, making them more versatile. Figure 1-5 shows the product identification of the air conditioner. At present, air conditioners have become the mainstream products in the market.

Structural parts (skeleton, cover, panel, wind deflector, electric control box, water tray, etc.) are mainly used for appearance, structural fixation, electrical isolation, wind direction guidance, etc.

Evaporator: working fluid and air heat exchange;

Through-flow detection fan: circulating air, outlet;

Motors, stepper motors: drive cross-flow fans and air deflectors.

Filter, etc.: dust removal and other functions;

Electric control board: pre-temperature collection, motor drive, etc.;

Display god open panel: remote control reception, working status display;

Wiring block: power cord and connection wire connection;

Outlet pipe: Condensate drain.
