Assessment of Energy Consumption in the Residential Building with a Heat Pump

Abstract

This paper analyzes the accuracy of the calculation of the energy needed for the heating of residential buildings by heat pumps. The reference value is the consumption obtained from the actual time course of temperature and the heat loss calculated by solving the partial differential equations. This value is compared with the results obtained using average daily and monthly temperatures and using a static wall model without heat capacity. The calculations are performed for the Carnot heat pump and for the currently used WPL18 heat pump.
