Sometimes the cost of drilling wells for the primary circuit of a heat pump is more than 50% of the cost of the entire project. According to the World Bank, the cost of conducting exploration work and an initial pilot drilling program for three to five geothermal wells is between $20 million and $30 million. temperature in the secondary circuit, heat pumps show less efficiency compar to traditional heating systems. Thus, they are better combin with the currently popular “warm floor” heating system: where the heat carrier is requir to have a temperature of.
In case it is necessary to obtain a high
Than with traditional batteries, the system of which requires the heat Kenya Email List carrier to be 75 º?. Not effective enough in cold climates. Heat pumps are more efficient (show higher efficiency) in European winters than in Russian winters – with negative temperatures down to -20 º?, and in some regions even up to -40 º?. In the case of heat pumps, the higher the efficiency, the smaller the temperature difference between the inlet and outlet of the heat pump. For example, other things being equal, let’s compare winter in Paris and in the Moscow region.
Which means that the compressor will consume
The air temperature in Paris in winter is about -3 º?, and the Buy Email List ground temperature is +10 º?, the difference is 13 º?. In winter, in the Moscow region, the average air temperature is -15 º?, and the soil temperature is only +5 º?, the difference is 20 º?. And if we take two identical private houses, which require, say, 12 kW of thermal energy per hour to heat, then in Paris we will ne to install a less powerful pump model, less electricity, it will be necessary to make fewer wells in the ground, which means the length of pipes and the volume of alcohol refrigerant will be less than in Russia.
