Abstract:   (3219 Views)

In this study, the optimal design of a hybrid system including solar collectors and Geothermal pumps to provide heating load of a building with technical and economic point of view hase been investigated. The performance of the various components of the system has been adjusted so that in addition to preheating the evaporator inlet fluid and setting this temperature to the ideal, coefficient of performance of heat pumps has also increased. First, optimal system has been evaluated technically and economically and optimal design with technical and economic considerations have been selected. selected model has 3.9 average performance factor for heat pumps, 30.375 square meters for collector area and 472.5 meters for pipes length (5 wells with 47.5 feet and the U-shaped tubes series were used). system Overall costs have been calculated, US $ 85,680 by minimizing the economic costs as the objective function and transferring the operational costs to the base year.

Keywords: Geothermal heating pump, solar collector, optimizing design, coefficient of performance, Trnsys software
