Propane (R290) Heat Pump

R290 Heat Pump from Budzar Industries

What is a Heat Pump

Heat pumps provide both heating and cooling to a building. In the winter, the heat pump provides heating by extracting heat from outside a building and moving it inside. In the summertime, cooling is provided by transferring heat from indoors to outdoors.


How Do Heat Pumps Work?

  1. Sourced heat is blown or pumped over the heat exchange surface of the exterior part of the heat pump.
  2. This heat is warm enough to cause the refrigerant liquid in the heat pump to evaporate and turn it into a gas.
  3. The gas then moves through a compressor, increasing pressure and causing the temperature to rise.
  4. The heated gas is passed over the internal heat exchange surface and then transferred into a central heating or hot water system.
  5. As the heat is transferred, the temperature of the gas falls, causing it to return to a liquid state.


Why Use R290?

Natural refrigerant Propane (R290) is being used as an alternative hydrocarbon refrigerant to synthetic F-Gas refrigerants more and more frequently as older, more environmentally damaging refrigerants are being phased out.

Propane as a refrigerant is incredibly well suited to use in heat pumps.   Propane (R290) has an operating temperature up to 70°C (158°F). It has good thermodynamic properties, a very low global warming potential (GWP), and zero ozone depletion potential (ODP), making it a practical natural hydrocarbon refrigerant to use with heat pumps.

The R290 heat pumps deliver the heating and cooling expected with heat pumps, but they also reduce carbon emissions while maximizing efficiency with cooling and heating systems.


About R290 Heat Pumps from Budzar Industries

The Natural Refrigerant Propane (R290) Chiller Heat Pump from the Budzar Green line of Budzar Industries is available in an air-to-water heat pump or air-to-air configuration. Both configurations reduce carbon emissions while maximizing efficiency and are suitable for medium to high-temperature applications requiring simultaneous heating and cooling.

The R290 Heat Pump provides a highly efficient, practical, cost-effective solution to standard HFC heat pumps. Propane chiller heat pumps from Budzar Industries feature advantages such as reduced load loss, system efficiency that matches or exceeds systems using synthetic refrigerants, and excellent safety levels.
