GHP (gas heat pump) compressor

GHP (gas heat pump) compressor

Gunma factory is the main manufacturing facility which integrated production of GHP compressor. We have been machining and grinding the compressor's central components and can measure the several microns of accuracy. We have long experience which cultivated with GHP compressor. If you have request of high accuracy, please inform us.

 

What is GHP ?
It is abbreviated word of "Gas Heat Pump Air Conditioner".
It is air conditioning system with heat pump which has compressor operated by gas engine.
The difference from electric heat pump air-conditioner (EHP) is operating system with electric motor or gas engine. Indoor unit and operation method are completely same as GHP type.

How to cool or heat the room by GHP?

Material has a property which absorbs surrounding heat to accomplish liquid gasitication and bringsheat to accomplish liquidation.
GHP uses this characteristic. It circulates coolant by compressor which is operated with a gas engine, and alternates between vaporization and liquefaction forcibly (heat pump cycle), and cool or heat the room.
