Some technical terms of air conditioning

1, indoor unit: the indoor part of the air conditioner, which is generally divided into wall-mounted, cabinet-mounted, ceiling-mounted, pipe-mounted and so on. , including evaporator, indoor fan, fan motor and control part.

2. Outdoor unit: the outdoor part of air conditioner, including compressor, condenser, fan and fan motor, and outdoor control part.

3. Compressor: a device for increasing the pressure of refrigerant gas, which changes low-temperature and low-pressure gas into high-temperature and high-pressure gas.

4. Refrigerant (refrigerant): The substance circulating in the refrigeration cycle system of air conditioner is the carrier of heat, which absorbs or releases heat through the change of state, so that the air conditioner can achieve the purpose of cooling or heating.

5. Refrigeration capacity: the heat absorbed by the indoor unit of air conditioner in unit time during refrigeration, and the unit is generally expressed in W or KW.

6. Input power (power consumption): When the air conditioner is running, the power consumed per unit time is generally expressed in W or KW.

7. Energy efficiency ratio (EER): the ratio of air conditioning refrigeration capacity to refrigeration input power. The larger the ratio, the better the refrigeration performance.

8. coefficient of performance (COP): the ratio of heating capacity to input power during air conditioning heating. The greater the ratio, the better the heating performance.

9. Heating capacity: the heat released by the indoor air conditioner during heating in unit time, and the unit is generally expressed in W or KW.

10. heat exchanger: a device in air conditioning, which is used to exchange heat between air conditioning system and surrounding environment.

1 1, condenser and evaporator: the condenser is the heat exchanger of the outdoor unit of the air conditioner, and the evaporator is the heat exchanger of the outdoor unit.

12. temperature sensor: an electronic component used by air conditioners to measure temperature.

13, R4 10A: It is a new type of environment-friendly refrigerant that does not destroy the ozone layer. Its working pressure is about 1.6 times that of ordinary R22 air conditioner, and its cooling (heating) efficiency is higher.
