What is a gas engine driven heat pump (GHP)? Gas engine driven heat pumps are a heat pump air conditioning system in which the compressor runs on an internal combustion engine using natural gas as fuel.
The gas engine driven heat pump is a traditional heat pump system in which the compressor runs on an internal combustion engine with natural gas instead of a conventional electric engine.
Better performance and energy efficiency
The use of the gas combustion engine for running the heat pump compressor provides a source of extra heat that guarantees higher performance and optimal comfort in extreme operating conditions. The latest generation equipment enables the joint production of electricity, heating and cooling, and domestic hot water (DHW).
The heat from cooling the engine can be utilised to totally or partially meet the DHW requirements of the building with a notable improvement to the system’s energy efficiency, which enables some of the building’s solar panels to be replaced, as provided for in the Building Technical Code.
High performance in cold air conditioning is obtained due to the recovery of heat from the engine, which avoids the use of electrical resistances and cycle inverters, which are habitual in electric systems.
The latest generation gas heat pumps offer an efficient alternative to building air conditioning. By using a single type of equipment running on natural gas, hot and cold can be obtained.
Easy installation, the same as conventional electric equipment. The possibility of working in any configuration.
There is no difference in installing a gas engine driven heat pump compared with its electric equivalent for traditional air conditioning use. All that is needed is the gas line for supplying the engine.
The installation of air conditioning can be designed with two pipes for providing only cold or only hot services or three or four pipes for simultaneously providing hot or cold depending on the use of the premises.
The selection of the terminal units is also very versatile, and direct expansion equipment can be used, or a heat exchanger can be employed for the water/air and mixed systems.
The main difference between GHPs and the traditional system is in non-conventional uses. The use of the gas engine provides an extra source of heat that can be utilised in the production of DHW with significant improvements in the performance of the installation which enables, if applicable, avoiding a large number of solar panels from being installed in the installation.
Gas engine driven heat pumps provide benefits to developers, customers and to society.
