Original Abstract

This article presents results of a study focusing on the evaluation of the real seasonal coefficient of performance (SCOP) of the air-to-water heat pump (HP) operating in specific conditions of the Central Europe. For evaluation is utilised a historical pattern of air temperatures from last 10 years. Real experimental data from the HP testing are used. The mathematical model is build-up which considers the behaviour of the considered building adhering to the demands on the supply of the heat energy. The influence of the HP operation during the warmer parts of the day with addition of the accumulation is assessed employing the created mathematical model. The model is used for parametric studies that evaluate utilizing of the accumulator and a method of heat pump control. The results show possible increase of SCOP up to 20 % with utilizing of predictive regulation. Studied configuration causes significant decrease of seasonal power consumption of air-to-water heat pumps.
