Gas Absorption Heat Pump

Gas absorption heat pumps are a type of heating and cooling system that utilize a natural gas or propane burner to power the absorption process. They function by utilizing a refrigerant and an absorbent to transfer heat energy from one location to another.

Unlike conventional heat pumps that rely on electricity to compress and expand refrigerant, gas absorption heat pumps utilize the heat generated from burning gas to drive the absorption process. This makes them a more eco-friendly and energy-efficient option.

Gas absorption heat pumps are commonly utilized in both commercial and residential buildings to provide heating, cooling, and hot water.

How Do Gas Absorption Heat Pumps Work?

Gas absorption heat pumps operate by utilizing a process known as absorption refrigeration, which involves several steps:

  1. Evaporation: A heat-absorbing fluid, referred to as the refrigerant, evaporates at a low temperature, absorbing heat from the surrounding air or water.
  2. Absorption: The refrigerant vapor is then absorbed into a liquid solution called the absorbent, resulting in a strong solution.
  3. Desorption: The strong solution is heated, causing the refrigerant to be released as a vapor, leaving behind a weak solution.
  4. Condensation: The refrigerant vapor is cooled and condensed back into a liquid, releasing heat in the process.
  5. Reabsorption: The weak solution absorbs the refrigerant vapor, completing the cycle.

This continuous cycle allows gas absorption heat pumps to efficiently transfer heat from a low-temperature source to a higher temperature output, making them a more energy-efficient option compared to traditional compression heat pumps.
