Gas engine driven heat pump - Characteristics, analysis of applications in buildings energy systems

Abstract

The paper concerns in particular gas engine driven heat pump. It presents where in the industry the heat pump is used with a mechanical drive. There are mentioned the main directions of development and first of all pumps driven by gas engine. The paper provides an overview of the advantages and disadvantages of this approach and circuit diagrams reproduced with heat pumps powered by a gas engine. Simple comparison shows the emissions for the creation of electricity (electric motor) and mechanical power (gas engine). A review of applications of gas engine driven heat pumps in Poland and abroad is presented. The basic parameters of the systems, principles of operation, operational problems and approximate costs are mentioned.
