Application and analysis of gas heat pumps

Presents the natural gas heat pump (GHP) system. Taking a demonstrating project as an example， analyses the initial investment and operation costs， and compares GHP with the electrical air conditioning system， electrical air conditioning plus boiler heating and directfired lithiumbromide absorptiontype refrigerating machine system， and considers that GHP has advantages of higher PER， better quality of heating， easier control， lower maintenance and running costs， good energy saving and meets the requirement of environment protection.
