Abstract
In the paper we presented a comparative analysis of the effect of the refrigerant used on the operation and performance of a heat pump with water-water and heat regeneration. Various sensitivity studies are presented comparatively for some eco-friendly refrigerants (R290, R600a, R454C, R152a) and R407C. Based on the exergetic analysis, the exergy destruction and loss were estimated for each device, depending on the destination and the operating regime. Graphic and numerical results are presented. In conclusion, a comparative analysis of the defined performance coefficient based on energy and exergetic efficiency is presented. The interest of the study is important due to the applicability of geothermal heat pumps in the field of air conditioning of residential and industrial buildings but also in agriculture for animal farms, for drying some agricultural products in a climate with controlled temperature and relative humidity, in addition the water can be used in summer for irrigation.
