The excavator air conditioner

Edit： Click：123 Date：2016-02-26

The excavator air conditioner is the same as the refrigeration principle of the household air conditioner that we are familiar with. They all use the principle of absorbing a large amount of heat energy when the sudden volume expansion of R12 or R134a is compressed and released. (Due to the destruction of the atmospheric ozone layer by R12, developed countries have switched to R134a as a refrigerant from 1996 due to environmental protection requirements.) The structure of the excavator air conditioner is similar to that of the household split air conditioner, and its compressor is often installed on the engine. , and driven by a belt (there are also direct drives), the condenser is installed in front of the radiator of the car, and the evaporator is inside the car, the low-pressure gaseous refrigerant from the evaporator flows through the compressor to become high-pressure high-temperature gas, After cooling and cooling through the condenser heat pipe, it becomes a high-pressure and low-temperature liquid, and then dehumidifies and buffers through the liquid storage dryer, and then flows to the expansion valve with a relatively stable pressure and flow, and finally flows to the evaporator after throttling and depressurization. The refrigerant evaporates when it encounters a low-pressure environment, absorbing a large amount of heat energy. The air in the cabin continuously flows through the evaporator, and the temperature in the cabin is lowered accordingly. After flowing through the evaporator, the liquid refrigerant becomes a low-pressure gas again, and is sucked into the compressor again for the next cycle. In the whole system, the expansion valve is the mechanism that controls the refrigerant entering the evaporator. Too much refrigerant entering the evaporator will not easily evaporate, and if too little cold air will be insufficient, so the expansion valve is the adjustment center. The compressor is the heart of the system and the power source of the system circulation.
