European winters than in Russian winters

Where the heat carrier is required to have a temperature of 45 º? than with traditional batteries, the system of which requires the heat carrier to be 75 º?. Not effective enough in cold climates. Heat pumps are more efficient (show higher efficiency) in E- 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. The air temperature in Paris in winter is about -3 º?, and the 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 need to Russia WhatsApp Number List install a less powerful pump model, which means that the compressor will consume 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. Thus, ceteris paribus, the cost of obtaining 1 kW of thermal energy in the Russian Federation is higher than in Europe.



This does not mean that heat pumps are inappropriate for use in Geothermal energy in other countries According to the World Bank, the global potential for geothermal energy is between 70 and 80 GW. However, only 15% of the known geothermal energy reserves are currently used for electricity generation in the world, and the total capacity of these installations is only 13 GW. Geothermal energy is actively used in the USA and China - these countries are now the undisputed leaders in this direction, but Japan is already catching up with them. Geothermal sources are successfully used for energy.
