air source heat pump
principle
When the air source heat pump is running, the evaporator absorbs heat from the ambient thermal energy in the air to evaporate the heat transfer medium. After the working medium vapor is compressed by the compressor, the pressure and temperature rise. The high-temperature vapor passes through a special annular ring bonded to the outer surface of the water storage tank. When the tube is connected, the condenser condenses into liquid and transfers heat to the water in the air source heat pump water storage tank. [2]
Heat pump working fluid
The heat transfer medium of an air source heat pump is a special substance. Its boiling point is minus 40°C and its freezing point is below minus 100°C under normal pressure. This substance is a liquid when it is cold, but it can easily evaporate into a gas, and vice versa. In actual operation, the evaporation limit temperature of the heat transfer medium in the air source heat pump is about minus 20°C, so the ambient temperature of 5°C is also "hot" for such a low temperature, even snowing temperatures, such as 0°C , is also hot by comparison, so some thermal energy can still be exchanged.
