In the cold winter or hot summer, people like to be in air-conditioned rooms , sometimes drinking coffee. This time is the most comfortable, and there are many questions here. What is the principle of air conditioning refrigeration and heating? cold and alone original rationale for professionals is very simple, but not the air conditioning of people do not know, renovation of home decoration today Xiaobian on and we take a look at what home is air-conditioned with the principle of it. How does household air conditioner work? The principle of household air conditioning is the second law of thermodynamics. It changes the state of the refrigerant by consuming mechanical energy, and then transfers the heat from the object with low temperature to the environment with high temperature. At the same time, the second law of thermodynamics runs through the entire air conditioner. This principle is often used and seen in our work and life. The principle of household air conditioning - the working principle of air conditioning unit refrigeration During cooling, the refrigeration compressor draws the low-temperature and low-pressure refrigerant gas in the evaporator (indoor heat exchanger) into the cylinder, and works through the compressor to make it a gas with high pressure and temperature, and is introduced into the outdoor through the four-way reversing valve. In the heat exchanger, a high-temperature high-pressure refrigerant gas cooling medium (air) exchanges heat, and heat is transferred to the medium (air), and the refrigerant condenses into a high-pressure liquid. The high-pressure liquid enters the indoor unit evaporator through capillary throttling and depressurization. The low-pressure liquid refrigerant in the evaporator immediately vaporizes and absorbs the heat of the surrounding medium (air) during vaporization, thereby cooling the surrounding air and cooling the indoor air. The fan continuously draws in indoor air, cools it through the evaporator and then enters the room, thus reducing the indoor temperature. The vaporized low-pressure low-temperature refrigerant is sucked and compressed again, so that it continuously circulates continuously to achieve continuous cooling. The principle of household air conditioning - the working principle of air conditioning unit heating When the heat pump is heated, after the four-way valve is reversed, the indoor unit becomes a condenser, and the high-temperature and high-pressure refrigerant gas discharged from the compressor is commutated and introduced into the condenser. In the condenser, the high-temperature refrigerant gas exchanges heat with the surrounding air and emits it. The heat condenses into a liquid refrigerant. The purpose of heating is also achieved by the action of the fan. The high-pressure refrigerant liquid leaves the condenser and is subjected to capillary throttling and depressurization, and then enters the outdoor heat exchanger, and continuously vaporizes therein, and absorbs the surrounding medium during vaporization. (air) heat. It is then sucked and compressed by the compressor, so that it is cycled and continuously circulated to achieve continuous heating. The principle of household air conditioning heating includes the heat pump type air conditioning heating principle and the electric auxiliary heat pump type air conditioning heating principle. The heat pump type air conditioner heating principle has the advantages of high efficiency, and it is realized by using indoor and outdoor heating cycles. The electric auxiliary heat pump type air conditioner heating principle is based on the heat pump type air conditioner, which increases the electric heating element to reduce the power consumption by the simple electric heating, and can reach the temperature range than the use of the simple heat pump, and starts at a low temperature. Low starting temperature -10 °C. Since being invented, air-conditioning has been loved by people, and it has become one of the most indispensable household appliances in today's life. Nowadays, air conditioners are very smart, and you can control the temperature yourself, in order to find the right temperature for users to use in the future. During the process, air conditioning is cleaned regularly. The above is the principle of home air conditioning introduced by Xiaobian today. It is over here, I want to know more about it. Please continue to pay attention to the decoration home network.
