The compressor plays an important role in refrigeration in the air cooler. The compressor is the core component of a cold air fan, mainly by reducing the refrigerant and converting it into a high-pressure and continuously high-temperature vapor. At this point, the energy of the refrigerant increases, which can effectively absorb heat.

Next, the high-pressure and high-temperature refrigerant releases heat from the cooler and becomes a high-pressure and low-temperature substance. Subsequently, the refrigerant enters the air conditioning evaporator through the air conditioning expansion valve, causing a sharp decrease in temperature and pressure throughout the surge process. At this time, the refrigerant absorbs heat from the air, causing the air to cool down.

Therefore, the compressor plays a role in reducing the refrigerant in the air cooler, enabling it to absorb, transport, and release heat during the cycle, thereby achieving the actual cooling effect in the air.
