Energy Conservation Potential of the Heat Pipe Heat Exchangers: Experimental Study and Predictions
The energy conservation potential of the heat pipe based heat exchangers (HPHXs) was studied in this research. To this end, a typical climate chamber as the representative of an air conditioning system was established. The performance characteristic of a typical eight-row HPHX was obtained based on the one week operation (168 h) to determine the performance characteristic curves. The coil face ...
متن کاملA Fault Diagnosis System for Heat Pumps
During the operation of heat pumps, faults like heat exchanger fouling, component failure, or refrigerant leakage reduce the system performance. In order to recognize these faults early, a fault diagnosis system has been developed and verified on a test bench. The parameters of a heat pump model are identified sequentially and classified during operation. For this classification, several ‘hard’...
متن کاملDirect heat projects and heat pumps
Geothermal Heat Pumps, or Ground Source Heat Pumps (GSHP), are systems combining a heat pump with a ground heat exchanger (closed loop systems), or fed by ground water from a well (open loop systems). They use the earth as a heat source when operating in heating mode, with a fluid (usually water or a water-antifreeze-mixture) as the media transferring the heat from the earth to the evaporator o...
متن کاملheat recovery from geothermal energy by employing refrigerants power cycles
some geothermal reservoirs have temperatures below boiling point and therefore natural steam can not be produced for power generation. refrigerant power cycles may be then employed to recover low temperature heat. in this article study is made of the power cycles of six different relligrants and most suitable refrigerants for this purpose are suggested
متن کاملGeothermal Heat Pumps
office building, or school, or replace your heating and cooling system, you may want to consider a geothermal heat pump (GHP) system. GHP systems are also known as GeoExchange, ground-source, or water-source heat pumps (as opposed to air-source heat pumps). Regardless of what you call them, energy-efficient geothermal heat pumps are available today for both residential and commercial building a...
