Air conditioning is the most commonly used air conditioning equipment in our daily life, which is widely used in various places such as offices, shops, homes, automobiles and industries. In the summer of modern life, you can't go anywhere without air conditioning. So some people joked that "my life is due to air conditioning." The working principle of the air conditioner is based on the refrigerant circulation. By adjusting the air temperature, humidity and flow rate, the indoor air can reach a comfortable state.

The principle of heating is to exchange the positions of the suction and exhaust pipes of the refrigeration system through electromagnetic commutation. The indoor coil of the original refrigeration evaporator becomes the condenser during heating, and the refrigeration system absorbs heat outdoors and releases heat indoors to achieve heating.

What is air conditioning:

1. When the air conditioner is refrigerating, the low pressure refrigerant evaporates and absorbs heat in the evaporator, while the high pressure refrigerant releases heat and condenses in the condenser. Air conditioning also has a name called heat pump, pump we all know what is doing, is to transport water and other liquids, the heat pump as the name suggests is to pump heat, the working principle of air conditioning refrigeration heating is to carry the heat back and forth with the refrigerant as the carrier, refrigerating refrigerant from the indoor heat transfer to the outdoor, so that the indoor temperature is reduced. During heating, the refrigerant absorbs heat from the outside and transfers it to the room, so that the indoor temperature rises, and the heat is not generated or disappeared in a vacuum. Most of the use of refrigerant under the action of the compressor, evaporation or condensation occurs, which causes the evaporation or condensation of the surrounding air to achieve the purpose of changing temperature and humidity.

2. Air conditioner hanging air conditioner is a unit used to provide treatment air to the space area generally closed. The refrigeration or heating system of the air conditioner is composed of four parts: compressor, condenser, capillary or electronic expansion valve and evaporator. In the split air conditioner, these four components are divided into indoor unit and outdoor unit. Its control board layout form and the method used are not the same, and the function Settings are more or less. Should be familiar with the various functions and use of the air conditioner, in order to correctly grasp the air conditioner startup and shutdown methods.

3. The central air conditioning system has a host and a terminal system. The medium used to load indoor heat and humidity load can be divided into all-air system, all-water system, air-water system and refrigerant system. Central air conditioning refers to a large air conditioning system, the system is composed of the host and the end, the host is divided into water-cooled units and air-cooled units, the end equipment is mainly composed of air conditioning units and fan coils, central air conditioning there is a refrigerant Freon VRV air conditioning unit. It is different from ordinary home air conditioning, central air conditioning can be used by large-scale buildings.
