Understanding the Refrigeration Cycle in Your HVAC System

The Refrigeration Cycle: The Heart of Your HVAC System

At Alan Energy Services, we believe that understanding how your HVAC system works can help you make informed decisions about maintenance and repairs. Today, we’re diving into the technical details of the refrigeration cycle, which is crucial for both air conditioning and heat pump systems.

The Four Stages of the Refrigeration Cycle

1. Compression: The cycle begins with low-pressure refrigerant gas entering the compressor. Here, it’s compressed, raising its temperature and pressure.

2. Condensation: The hot, high-pressure gas moves to the condenser coil, where it releases heat to the outside air and condenses into a liquid.

3. Expansion: The liquid refrigerant passes through an expansion valve, which reduces its pressure and temperature dramatically.

4. Evaporation: The cold, low-pressure liquid enters the evaporator coil inside your home. It absorbs heat from the indoor air, evaporating back into a gas.

Why Understanding This Matters

Knowing these stages can help you identify potential issues in your HVAC system. For example:

  • If your AC isn’t cooling properly, there might be a problem with the evaporation stage.
  • Strange noises from your unit could indicate compressor issues.
  • Ice on the outdoor unit might suggest problems with the condensation process.
