Heating and Cooling Feasibility of Absorption Heat Pumps Driven by Evacuated Tube Solar Collectors: An Energy and Economic Analysis

Thermal compression-driven heat pump plants usually use solar collectors only providing direct heating when possible and low-temperature (but higher than outside air) cold sources for the evaporator otherwise. At same time, drive absorption chillers during summer. In this paper, possibility of employing evacuated tube to an that operates in summer as a chiller was evaluated from both energy economic points view. The ground at low temperature were used sources. can be recharged by cooling absorber/condenser mid-seasons. yearly operation analysis two different climates here proposed also considered utilization suitable storage capabilities varying size probes, field, Generator Tank.
