The Functions Of Air Conditioner Compressors

1 – Air Transfer

The main and most important function of your air conditioner is to transfer heat into your unit. When the air begins to rise above your rooms default temperature, the vents suck the humidity out via the condenser coil. After the air has been absorbed by the unit, the compressor begins to send it to the condenser coil. This is where the magic happens as the balmy air is converted into the breezy and chilly air that you know and love.

2 – Removes Humidity

Besides just transferring the air, another critical function is eliminating the humidity in your room. The moment the compressor begins to malfunction, your room will begin to feel moist and damp.

3 – Liquid Compression

After the air has been absorbed by the unity, the compressor turns it into liquid. At this point, it then travels all the way down to the expansion valve where it then cools the warm liquid. As the air conditioner fluids flow into the compressor, it does so in the form of low-pressure gas. So, if your compressor is experiencing problems, the liquid wouldn’t be able to be fully processed; hence warm air is produced even though the unit is expected to produce cool or cold air.

4 – Removal And Condensation of Hot Refrigerated Gas

The condenser also removes and condenses hot gas within the unit. This enables it to exhibit a higher temperature and pressure.
