What temperature does the heat carrier need to achieve compared to conventional batteries? Its system requires a heat carrier of . Doesn't work well in cold climates. Heat pumps are more efficient (show higher efficiency) in winters in Europe than in Russia. Negative temperatures down to, and in some regions even up to. In the case of heat pumps, the higher the efficiency, the smaller the temperature difference between the heat pump inlet and outlet. For example, ceteris paribus, let's compare winters in the Paris and Moscow regions.
The temperature in Paris in winter is approx. , while the ground temperature is . In winter, in the Botswana Email List Moscow region, the average air temperature is, while the soil temperature is only, with a difference of . If we take two identical private houses to heat, say, kilowatts per hour of thermal energy, then in Paris we will need to install a less powerful pump model, which means that the compressor consumes less electricity and needs to be pumped underground There are fewer wells, which means that the length of the pipeline and the volume of alcohol refrigerant will be smaller than in Russia.
Therefore, all other things being equal, the cost of obtaining a kilowatt of thermal energy is higher in the Russian Federation than in Europe. But this does not mean that heat pumps should not be used in the Russian Federation, just that the capital investment will be higher. They are recommended for use where gas supply is not possible. According to the World Bank, the global geothermal energy potential ranges from 1 to 1 GW. However, only one of the world's known geothermal energy reserves is currently used for electricity generation, and the total installed capacity of these installations is only gigawatts.
