Air conditioners


1. Classification of household air conditioners
1. Classification according to structure: integral type, also called window type and split type,
2. Classification according to function: single cooling type and hot and cold type
3. Classification according to operation mode: ordinary type, Wire control and remote control
4. Other classification methods: indoor units are classified into one for two and one for three; the climate environment is classified into T1, T2, and T3, and T1 air conditioners are generally used in China.
2. The basic structure of household air conditioner
consists of four parts: refrigeration system, ventilation system, electrical control system and cabinet system. The
refrigeration system is the most basic system of each type of air conditioner. It is the main part to realize the cooling or heating function of the air conditioner. .
The ventilation system is the part that realizes heat exchange. It sends the cold energy generated by the refrigeration system to the room and sends the heat in the condenser to the outside.
Electrical control is the operating system of the air conditioner. There are two ways of mechanical control and electronic control. Only with it can the air conditioner work according to people's wishes.
The cabinet system is the supporting base frame of the air conditioner, and various parts are installed on it. The four systems form a whole according to their respective functions and become a complete air conditioner.
3. The working principle and main function of the air conditioner.
The motive power provided by the compressor to the freon makes the fluorine flow in a certain direction in the whole system, and the three-state conversion of freon is controlled by adding a capillary tube at a certain position in the system. So as to achieve the purpose of heat absorption and heat release, the heat absorbed and released by the evaporator and the condenser diffuses the energy area, and the energy is rapidly diffused by the blow of the internal and external fans to achieve the purpose of heat dissipation.
The main functions of the air conditioner: reduce temperature, dehumidify and prevent moisture: filter the air; the new air conditioner is equipped with an electrostatic air filter, which can effectively filter 0.01 micron dust particles.
Fourth, the specifications and models
of the air conditioner 1, the specifications of the air conditioner
It is divided by cooling capacity (or heating capacity). The cooling capacity refers to the heat absorbed from the room or a certain area and transferred to other areas during the cooling operation of the air conditioner. National standards stipulate that the unit of calculation is "watt" or "kilowatt", and the symbol is "W" or "KW". Some manufacturers and consumers on the market also use "hp" to indicate the specifications of air conditioners. Horse is a power unit used before. Its relationship with "watt" is about 735 watts equal to 1 horsepower. Generally, 1 HP is 2500W, 2 HP is 5000W, and 3 HP is 7100W.
When choosing an air conditioner, you should first measure the usable area of ​​your single room, and then multiply it by the usable area of ​​your room according to 150-200W per square, that is, you know the cooling capacity you need, and in general, a suitable room for a horse (2500W) The usable area is 11-15 square meters, and the usable area suitable for one and a half horses (3500W) is 18-25 square meters. The quality of some air conditioners determines their cooling capacity, which depends on the brand. .
The maximum allowable length of the air-conditioner connecting pipeline is stipulated that one horse cannot exceed 8 meters, 1.5-2 horses cannot exceed 10 meters, and 2 horses cannot exceed 15 meters. The height difference between indoor and outdoor units should not exceed 5 meters.
2. The meaning of domestic air conditioner symbols:
such as model: KF (R)-23GW, KC-23, KF-50LW, K stands for air conditioner F stands for split R stands for heating and cooling C stands for window unit and the number behind the bar stands for the cooling capacity For example: 23 means the cooling capacity is 2300W, L means indoor floor-standing G means indoor hanging machine, W means outdoor machine.
5. The main difference between
split air conditioner and window air conditioner Split air conditioner can reduce indoor noise generally by about 40dB, but the structural installation is more complicated, while window air conditioner is simple to install, and it will not leak fluorine during installation, and the manufacturing cost is lower. .But the noise is generally around 50dB, and the applicable area is small.
The cause of the noise of the air conditioner: It is mainly produced by the motor, compressor, and air outlet, but the frequent start of the compressor and improper installation can also cause noise.
