Talk about the function of accessories of central air conditioning?
Details
Compressor, copper tube, expansion valve, condenser, evaporator, axial fan, controller (including temperature probe), freon (general name, many varieties) better need electronic expansion valve. Water system also has pumps, all kinds of water pipe fittings. Large also have a condensing tower, removable plate heat exchanger. 1. Central air conditioning accessories: copper pipe Copper tube has high thermal conductivity, good heat transfer effect, good toughness and strong machinability, so it is widely used in the field of refrigeration. In the installation of central air conditioning, the function of copper tube is to connect the internal and external units to form a closed system. The refrigerant circulates in the copper tube to realize the refrigeration and heating of the room.
2. Central air conditioning accessories: insulation cotton Thermal insulation cotton (copper pipe insulation) has two functions. The first is heat preservation to prevent temperature loss. If there is no insulation cotton, it will directly affect the air conditioning effect, and condensation will be produced during air conditioning refrigeration, and the accumulated water drops to the ceiling, which will damage the aesthetics. Second, to prevent copper tube aging, if exposed to the outside for a long time, the copper tube will be oxidized and blackened, reducing its service life.
3. Central air conditioning accessories: condensate pipe Under the condition of air conditioning running and refrigeration, condensate water will be produced. The function of condensate pipe is to remove the condensate water from the fan coil unit (or air conditioner). Generally, the condensate pipe is hidden in the ceiling and will be closed at last.
4. Central air conditioning accessories: thermostate Temperature controller is an important part of central air conditioning. It has four function keys: on key, mode key, wind speed key and temperature setting key. Among them, mode key is used to set cooling or heating, while wind speed key and temperature setting key can set the wind speed and temperature according to personal preference. Any different place, you can freely control the temperature through it.
