Developing of Heating and Cooling Universal System Sourced by New Type of Heat Pump and Method for Its Design

Abstract

At present closed and open loop geothermal heat pumps are in use. Nevertheless, they have disadvantages, which seriously limit their wide use. First disadvantage is the shortage of rather large free areas for laying underground heat exchangers in form of rather long pipelines. This problem arises especially in towns and large cities. Second disadvantage is the rather expensive and often not affordable construction of heating and cooling systems, sourced by heat pumps. For overcoming mentioned disadvantages and increasing energy efficiency and cost effectiveness of heating and cooling systems a new structure of heat pump and method for its calculation and design are suggested. Because the developed heat pump is able round year efficiently satisfying thermal needs for different purposes of a house it is called “universal heat pump”.
