Termodinamička i ekonomska analiza rada geotermalne toplotne pumpe tipa voda-voda

Abstract

Termodinamička analiza rada monovalentnog sistema geotermalne toplotne pumpe tipa voda-voda izvršena je sa aspekta praćenja promene njenog koeficijenta grejanja i efektivnog koeficijenta grejanja, a u zavisnosti od promene temperature grejne vode u grejnim telima, temperature vode u crpnom bunaru, te promene temperature bunarske vode na isparivaču toplotne pumpe. Ekonomska analiza geotermalne toplotne pumpe izvršena je poređenjem sa grejnim sistemom sa gasnim kotlom. Ustanovljena je ekonomska zavisnost isplativosti sistema od dubine bunara i cene bušenja bunara.

Thermodynamic work analysis of monovalent system of groundwater source heat pump was performed from the aspect of monitoring changes in its coefficient of performance and the effective coefficient of performance, depending on a change of temperature of the heating water in the heating elements, water temperature in pumping well, and a change in temperature of water from a well in the evaporator of the heat pump. Economic analysis of the geothermal heat pump was compared with the heating system with a gas boiler. The economic cost effectiveness of the system, depending on the depth of the wells and the cost of drilling the well, was established.
