No, it is not possible to charge a portable air conditioner with no compressor. The compressor is a crucial component of any air conditioning system, including portable air conditioners. It plays a central role in the cooling process by compressing and circulating refrigerant gas through the system.
Here's how the cooling process works in a typical air conditioner, including portable ones with a compressor:
Compression: The compressor takes low-pressure refrigerant gas from the evaporator and compresses it into high-pressure, high-temperature gas.
Condensation: The hot, pressurized gas flows through the condenser coils, where it releases heat to the surrounding air and condenses into a high-pressure liquid.
Expansion: The high-pressure liquid refrigerant then passes through an expansion valve or an orifice, where it undergoes a sudden drop in pressure. This causes the refrigerant to evaporate and turn into a low-pressure, low-temperature gas.
Evaporation: The cold refrigerant gas absorbs heat from the indoor air as it passes through the evaporator coils, cooling the air in the process.
Air Circulation: The now-cooled air is blown into the room, while the warm refrigerant gas returns to the compressor to repeat the cycle.
Without a compressor, the air conditioner would lack the means to compress and circulate the refrigerant, rendering it unable to cool the air effectively. The compressor is the heart of the cooling system, and without it, the portable air conditioner would function as a fan blowing air without providing any cooling effect.
If you have a portable air conditioner that is not cooling properly or has a malfunctioning compressor, it's best to contact a qualified HVAC technician or the manufacturer for proper diagnosis and repair. Attempting to charge or modify the system without the appropriate knowledge and equipment can be dangerous and may further damage the unit.
