Simulação de uma bomba de calor com condensador em contracorrente para aquecimento de água.

Abstract

An air to air heat pump computer program was modified to simulate a heat pump system for residential water heating, under steady state conditions. For that purpose a computer model of a counter flow concentric-tube condenser was developed and included in the program. The sensitivity of the model to different dimensions of the components and various operating conditions lead to the conclusion that the modified program is capable of predicting trends on the system performance, being a useful tool for designing and optimizing a heat pump for water heating.
