What is the principle of air conditioning and refrigeration When the temperature is relatively high in the hot summer days, I believe many of them are also inseparable from the air conditioner. In the summer, it can be said that this life is given by the air conditioner. Everyone knows that the air conditioner can cool and heat, and can adjust the temperature according to your own settings to give yourself a comfortable feeling. However, few people know what is the principle of air conditioning and refrigeration? here we come to find out.
The principle of air conditioning refrigeration is actually after the air conditioner is energized, and then the low-pressure refrigerant vapor in the system is sucked by the compressor and compressed into high-pressure steam, and then discharged to the condenser to make the indoor air continuously circulate and flow, so as to achieve A temperature lowering effect. In detail, it is the air conditioner compressor to compress the gaseous freon into a high temperature and high pressure liquid freon, and then send it to the outdoor unit for heat treatment, so the outdoor unit blows out hot air. And the liquid Freon enters the evaporator through the capillaries, so that the space will become larger, and the pressure will become smaller, so that the liquid Freon will be vaporized, which will become gaseous low temperature Freon, which absorbs a lot of heat, makes the evaporator cool, and the fan of the indoor unit will blow away the indoor air from the evaporator, so the cold air is blown out of the indoor unit; And the water vapor in the air will condense into water droplets after encountering cold evaporation, and then will flow out along the water pipe, which is why the air conditioner will emit water, and then continue to cycle for gaseous Freon. If you look closely, we may find that when the air conditioner is heating, there is a component called a four-way valve. This component makes the flow direction of Freon in the condenser and evaporator opposite to that in cooling, so in heating At that time, the cold air was blown outdoors, and the indoor unit was blown by hot air, and the principle used was the liquefaction of junior high school physics.
