Four seas network: hot summer is coming, air conditioning has become an important electrical appliance that people can't do without in summer. Many people rely on air conditioning in summer, hiding in the air conditioning room to enjoy the cool summer. As we all know, the freon in air conditioning is very harmful to the atmosphere when it is used for a long time. So fluorine-free air conditioning came out, more and more families began to buy it. So how much do you know about fluorine-free air conditioning? Let's learn about the fluorine-free air conditioner with Xiaobian!
The refrigeration and heating principle of fluorine free air conditioner
Brief introduction of fluorine free air conditioner
According to the regulations, R22 refrigerant will be phased out by 2020, and R410A, a fluorine-free environmental protection refrigerant, is its main environmental protection substitute. Therefore, it is called "fluorine-free" air-conditioning that using R410A instead of traditional refrigerant. 'fluorine free air conditioning' is integrated into DC frequency conversion technology, that is, 'fluorine free frequency conversion air conditioning'.
Refrigeration and heating of air conditioner need refrigerant, which is often referred to as the "blood" of air conditioner. It is the key to the heat absorption and release of air conditioner. According to statistics, at present, at least 80% of China's domestic air conditioners use R22 traditional refrigerants, which has a great impact on the ozone layer and seriously endangers the human living environment and the overall ecological environment.
Refrigeration principle of fluorine free air conditioner
In the electric refrigeration system of the air conditioner, the refrigerant low-pressure steam compressor draws in and compresses the high-pressure steam, which is discharged to the condenser coaxial flow fan and inhaled outdoors. The air flows through the condenser to take away the refrigerant heat to condense the high-pressure refrigerant steam. The high-pressure liquid and high-pressure liquid are sprayed into the evaporator through the filter and throttling mechanism, and the corresponding low-pressure evaporation absorbs the surrounding heat. The same flow fan cuts off the air Heat exchange is carried out between the fins of evaporator, and the hot and cold air is sent to the indoor air to cut off the circulation flow, so as to reduce the temperature.
Heating principle of fluorine free air conditioner
The heat pump system compresses the condenser with the refrigeration system, heats the indoor air conditioner, works in refrigeration, evaporates in the low-pressure refrigerant liquid evaporator, absorbs heat, releases heat in the high-temperature and high-pressure refrigerant condenser, condenses the heat through the electromagnetic reversing refrigeration system, changes the original refrigeration work evaporator's indoor coil into the heat condenser, and the outdoor heat absorption of the refrigeration system releases heat to the indoor Make heat.
