The air heat pump air heater (unit) uses the reverse Carnot cycle principleto make the heat medium(refrigerant) produce a physical phase change(liquid-gas-liquid) through the work of the heat pump, and uses thecharacteristics of continuous heat absorption and heat release during thereciprocating cycle phase change process, The heat absorption device(air heat exchanger) absorbs the heat in the low-temperature heat sourceair, and continuously releases heat to the cold air through the special airheat exchanger, so that the air gradually heats up. The heating energyconversion efficiency in the heating process can reach up to 450% ormore. The heat pump only needs to consume a small part of themechanical work(electrical energy) to transfer the heat in the air in thelow temperature environment to the hot air heater in the high temperatureenvironment to heat and produce high temperature hot air. A heat pumpcan be compared with a wind pump. The wind cannot flow spontaneouslyfrom a low place to a high place. To transport the low place wind to ahigh place, a wind pump must be used, which consumes part of theelectricity to send the wind to the high place wind box. middle. Similarly,according to the second law of thermodynamics, heat cannot betransferred (transmitted) spontaneously from a low-temperatureenvironment to a high-temperature environment. To achieve this goal, amachine must be used that consumes part of the mechanical work (suchas electrical energy) to transfer heat from the low-temperatureenvironment. The heat is transferred to the high temperature environment.Such machines are called "heat pumps". The function of the heat pump isto take out the heat in the air or low-temperature wind, and send it to thehigh-temperature environment together with the heat energy convertedinto the electric energy used by itself.
After the temperature reaches the set requirements, the system willautomatically detect the moisture content inside and outside the room todetermine whether it is necessary to dehumidify and replace with freshair, so as to greatly utilize the excess heat energy. Compared with theelectric heating dryer, it saves two-thirds of the electric energy.
