What is air energy and how does air energy work?High Air Source Water Heat Pump (60degree Water Outlet) Law Of Conservation Of Energy
Air energy, the low-grade heat energy contained in the air, is also called air source. The law of conservation of energy tells us that energy will not be produced out of thin air, nor will it disappear out of thin air. But according to the second law of thermodynamics, heat cannot be transferred from a low-temperature object to a high-temperature object without other changes. Although air energy is inexhaustible, if the energy absorbed in the air needs to be transferred to a high temperature environment, it needs to consume electricity or heat. This technology is called an air source heat pump.
How does the air (heat pump) water heater High Air Source Water Heat Pump (60degree Water Outlet) Law Of Conservation Of Energy work?
The compressor system operates and works to absorb heat in the air to produce hot water. The specific process is: the compressor compresses the refrigerant, and the refrigerant whose temperature rises after compression passes through the condenser in the water tank to produce hot water. The refrigerant after heat exchange returns to the compressor for the next cycle. In this process, the heat of the air is absorbed into the water through the evaporator to produce hot water. Such a new-generation water heater that heats by compressor air is an air (heat pump) water heater. Air (heat pump) water heaters are just such products. This is how the air (heat pump) water heater works.
When the air energy heat pump is in operation, the evaporator absorbs heat from the ambient heat in the air to evaporate the heat transfer working fluid. The working fluid vapor is compressed by the compressor and the pressure and temperature rise, and the high temperature vapor is permanently bonded to the outer surface of the water storage tank. When the loop tube condenser condenses into liquid, the heat released is transferred to the water in the air source heat pump water tank. The condensed heat transfer working fluid returns to the evaporator through the expansion valve, and then is evaporated again, and so on.
The heat transfer working fluid of air energy heat pump is a special substance. Its boiling point is minus 40℃ and freezing point below minus 100℃ under normal pressure. The substance is liquid when it is cold, but it is easily evaporated into gas, and vice versa. In actual operation, the evaporation limit temperature of the heat transfer fluid in the air source heat pump is about minus 20°C, so the ambient temperature of 5°C is also "hot" to such a low temperature, even the temperature of snow, such as 0°C , Is also hot in comparison, so some heat energy can still be exchanged.
