R22 Mobile Portable Air Cooler With 10-12 Degrees Lower Air Outlet Temperature

10-12 Degrees Lower Air Outlet Temperature With Mobile Air Cooler

Using of a refrigerant in a mobile air cooler allows for the transfer of heat from the air to the refrigerant and then the release of that heat to the outside, resulting in the cooling of the air.

1. Evaporation: The refrigerant in the mobile air cooler is in a liquid state at low pressure. When it passes through an evaporator, it absorbs heat from the surrounding air due to its low boiling point. As a result, the refrigerant changes from a liquid to a gas.

2. Compression: then compressed by a compressor. The compressor increases the pressure of the refrigerant gas, which also increases its temperature. This step is necessary to prepare the refrigerant for the next stage of the cooling process.

3. Condensation: The high-pressure and high-temperature refrigerant gas then enters a condenser. In the condenser, the refrigerant releases the heat it absorbed earlier to the outside environment (such as the surrounding air or a cooling medium like water). As the refrigerant releases heat, it condenses back into a liquid state.

4. Expansion: The condensed liquid refrigerant then passes through an expansion valve. The expansion valve reduces the pressure of the refrigerant, allowing it to enter the evaporator again at a lower pressure and start the cycle anew. This continuous cycle of evaporation, compression, condensation, and expansion enables the mobile air cooler to continuously provide cooled air.
