Saving hot air drying

Jin into high temperature heat pump consists of an evaporator, compressor, condenser and expansion valve four parts, by constantly complete evaporation of refrigerant (absorb heat from the environment) → compression → condensation (gives off heat) → throttle (cooling) → evaporation thermodynamic cycle process, which will environments where heat is transferred to the heating target strength to pump essentially a heat transfer devices. Role is to absorb heat from the surrounding environment, through the expansion of energy to improve the compactor, pass it on to the heated object. Works the same refrigerator, work in reverse Carnot cycle, the difference is not the same as the operating temperature range. Refrigerant circulating in the system, after completion of the gas compressed by the compressor boost heating process (temperature up to 130 ℃); high temperature heat released into the condenser, the object to be heated is heated; down into the low-pressure expansion valve closure cryogenic gas (temperature as low as minus 10 ℃) to the evaporator, the refrigerant heat flow in contact with the outside of the evaporator, the temperature difference due to heat exchange (heat), heat refrigerant after the compressor and compressed again into the high pressure hot gases into the condenser to pass the absorbed heat to the heating object. The entire work process is that the heat transport process, refrigerant circulates continuously achieve the low temperature heat absorption into the outside heated subject to high temperature heat heating (up to 105 ℃).
