Heat pump is essentially a lifting device, the use of high temperature heat pump drying unit reverse Carnot principle, absorb heat from the surrounding environment, and pass it to the object to be heated (high body temperature), which works with refrigeration the same machine, are working in reverse Carnot cycle, except that the operating temperature range is not the same. Heat pump dryer - heat pump drying unit works, mainly fin evaporator (outside the machine), a compressor, a condenser fins (the machine) and the expansion valve four parts, so that the working fluid through continuous complete evaporation (absorb heat in outdoor environments) → compression → condensation (release heat in the room drying room) → throttle → thermodynamic cycle re-evaporation process, so the external low-temperature environments where heat is transferred to the drying room, the refrigerant in under the action of the compressor in the system circulation. It is done in the compressor gaseous boost heating process (temperature up to 100 ℃), releasing it into the machine dry in room temperature air heated by the heat, while they have been cooled and converted to liquid flow, when it runs to the outside of the machine After the liquid evaporates quickly transformed into gaseous again, while the temperature can drop to -20 ℃ ~ -30 ℃, then the air around the heat sink will continuously transfer heat to the refrigerant. Heat pump heat pump drying schematics drying unit is in operation, with the ordinary, like air conditioning and heat pump units, absorb the energy of low environmental media QA in the evaporator: it is itself part of the energy consumption, namely the compressor power QB: By working fluid circulation system when the line in the condenser heat QC, QC = QA + QB, so the efficiency of heat pump drying unit is (QB + QC) / QB, and the heating efficiency of other heating devices are less than 1, so heating efficiency heat pump drying unit is much larger than other heating equipment efficiency, we can see the effect of high temperature heat pump drying unit using a drying device can save energy, while also reducing emissions of CO2 and other pollutants, to achieve energy saving . Heat pump dryer - heat pump drying unit using spaces for hotels drying bedding, seafood, vegetable dehydration, AD black fungus, melon seeds, peanuts, fruits and vegetables, meat, sausage, tobacco, leather, mushrooms, wolfberry fruit, dried fruit, mosquito coils, tribute incense, cloth, clothing, food grains, noodles, dried bean, fertilizers, pharmaceuticals, medicines, paper, wood, seeds, sludge, gypsum, metal products, metallurgical products, mining by-products, chemical products flue gas desulfurization gypsum, clay, grass, tobacco, pulverized coal, coal, lignite drying. In terms of industrial hot water, but also to satisfy the thermostat electroplating factory plating solution, slaughterhouse hot water heating and insulation, hot water supply star hotels and industrial hot water needs. Heat pump dryer - Technical prospects material drying process is a huge energy-consuming process, according to statistics, in the most developed countries in the energy consumed for drying the country's total energy consumption by 7% -15%, and the thermal efficiency only 25% -50%, and most especially the drying process will have an impact on heat-sensitive materials (such as food and biological materials) to its color, nutrition, flavor and organizations. Heat pump drying technology has less energy consumption, less environmental pollution, high drying quality, wide range of advantages, its excellent energy-saving effect has been a variety of domestic and international test certificate Institute
