摘要：The article describes the innovative combination of the heat
pump's operation with the heating network called as cHPNes. The heat
pump's lower heat sources used so far are air, water or ground. Their
efficiency is usually incoherent with the energy needs of recipients. In the
period of the lowest temperatures of the source, we have the highest
demand for heat in the supplied facility. A combination of the water heat
pump and the heating network is aimed at increasing the energy efficiency
(COP) of the heat source and indirectly increasing the participation of
renewable energy in the energy balance of buildings. The essence of the
new solution is the use of returning water in the heating network to supply
the heat pump evaporator. The working medium temperature of the heating
network on the return in the all-year cycle is stable and high, which allows
further use of energy of the heating water on the return. These are the two
main advantages of network water used as the lower heat source, allowing
for stable and efficient operation of the heat pump with COP above 13.
This solution is a response to the need to improve the energy efficiency of
highly urbanized spaces.
