The snowflake sign of air conditioner is cooling mode. The refrigeration principle of air conditioner is that the compressor compresses gaseous refrigerant into high temperature and high pressure gas and sends it to the condenser for cooling. After cooling, it becomes a medium-temperature and high-pressure liquid refrigerant, which enters the drying bottle for filtration and dehumidification. The medium-temperature liquid refrigerant is throttled by the expansion valve (throttling element), so that the pressure of the low-temperature and low-pressure gas-liquid mixture (with many liquids) is reduced, and it is vaporized by the evaporator to absorb the heat in the air, and then it becomes gaseous, and then it returns to the compressor to continue compression and refrigeration. When heating, there is a four-way valve to make the flow direction of freon in condenser and evaporator opposite to that in refrigeration, so when heating, cold air is blown outdoors and hot air is blown indoors.
Air conditioning is air conditioning. Refers to the equipment that manually adjusts and controls the temperature, humidity, flow rate and other parameters of ambient air in buildings or structures. Generally, it includes cold source/heat source equipment, cold and hot medium transmission and distribution system, terminal device and other auxiliary equipment. It mainly includes refrigeration host, water pump, fan and pipeline system. The terminal equipment is responsible for carefully handling the air state by using the cold heat from transmission and distribution, so that the air parameters of the target environment can meet certain requirements.
Air conditioning is an indispensable part of people's modern life. Air conditioning not only provides people with coolness, but also easily causes diseases, such as "air conditioning disease", which needs to be used with caution. The main forms of air conditioning are: cabinet air conditioning, on-hook air conditioning, water air conditioning, window air conditioning (semi-indoor and semi-outdoor), central air conditioning, one-on-two air conditioning (one outdoor unit controls two indoor units at the same time) and so on.
