heat demand - Opis:
- The article presents the energy performance of a heat pump. The coefficient of performance was taken into account, which is the ratio of the heating energy obtained to the supplied electrical energy necessary for the compressor operation. The focus was on the issue of operating costs of using heat pumps. These costs are mainly influenced by two factors. Firstly, energy performance and the purchase price of electricity. The second factor is investment costs. Heat gains from solar energy were characterized. The value of the solar radiation transmission coefficient for the double glazing was assumed (TR = 0.7). Solar gains were shown in January for windows on the eastern and western facades. The analysis covered the seasonal heat demand for heating. The studies and calculations took into account the occurring heat losses and heat gains from the sun and internal sources with their utilization rate. Particular attention was paid to the fact that the peak power of heating appliances can be calculated by knowing the value of the annual energy demand for heating a building that takes into account the most severe external conditions prevailing in a given climate zone, i.e. the minimum outside temperature.
