Gas Absorption Heat Pumps
Gas absorption heat pumps provide energy-efficient gas-powered heating and cooling systems for commercial, industrial and residential buildings. They can both heat and cool the air in a building, as well as heat the water.
They use the freely-available, plentiful natural energy from the ground, the air and from water and turn it into a higher or lower temperature for building heating or cooling, and for water heating.
The most common heating technologies are typically gas boilers and electric heat pumps. Gas absorption heat pumps combine the benefits of both these systems to provide a reliable, cost-effective and constant energy source.
They are fired by natural or propane gas and don’t use any refrigerants that might be harmful to the environment. Using the earth’s natural renewable energy, they can supply chilled water for cooling in summer and hot water for heating in the winter. They even save space because they are suitable for installation outdoors.
Gas absorption heat pumps achieve a lower carbon footprint and reduce costs. By utilising the free energy found in the environment, they can provide up to 65% additional heat. The highly efficient gas condensing burner, cuts operational costs due to the lower price of gas.
How do gas absorption heat pumps work?
The process is simple. The heat pump extracts heat from the source using a gas burner that employs the generator-absorber heat exchange cycle. Then, for the refrigeration cycle, the pump uses a water and ammonia solution, whereby the ammonia is the refrigerant and the water is an absorber.
Here is the process broken down into stages:
What are the benefits of Gas Absorption?
Gas absorption systems:
Improve the energy efficiency class of a building
Can be installed outside, saving space
Have zoning capabilities
Need a smaller electric service
Have a low electric consumption
Are environmentally friendly
Have low running costs
Reduce CO2 emissions
Do not use compressors
Robur Gas Absorption Heat Pumps can supply hot water up to 140°F (60°C)
They can be easily retrofitted to integrate with existing installations
