Introduction to the working principle of air energy dryer

Air source heat pump technology is an energy-saving and environmentally friendly heating technology based on the principle of reverse Carnot cycle. The air energy heat pump drying system obtains a low-temperature heat source through natural energy (air heat storage), and becomes a high-temperature heat source after the system is integrated with high-efficiency heat collection, which is used to take (supply) warm water or supply hot water. The heat collection efficiency of the whole system is high. Heat pump has four advantages: energy saving, comprehensive utilization of energy, environmental protection, combination of cold and heat, high utilization rate of equipment and saving investment. Fourth, because it is driven by electricity, it is more convenient to control, so the heat pump has attracted everyone's attention.

Air energy dryerThe working principle;

(1) Compression process: The low-temperature and low-pressure refrigerant gas is compressed into high-temperature and high-pressure gas by the compressor. At this time, the work done by the compressor is converted into the internal energy of the refrigerant gas, which increases the temperature and pressure, which is thermodynamically called an adiabatic process.

(2) Condensation process: The high-temperature and high-pressure refrigerant gas from the compressor flows through the condenser, is continuously released to the outside by wind or water, and condenses into a medium-temperature and high-pressure refrigerant liquid. During the liquefaction process, the temperature of the refrigerant decreases, but the pressure remains the same. This is thermodynamically called an isobaric process.

(3) Throttling process: After the medium temperature and high pressure refrigerant liquid from the condenser is throttled by the throttling device, it becomes a low temperature and low pressure refrigerant liquid. Thermodynamically called isenthalpic process.

(4) Evaporation process: The low-temperature and low-pressure refrigerant liquid from the over-throttling device flows through the evaporator, continuously absorbs heat to the room with wind or water, and evaporates into low-temperature and low-pressure refrigerant gas. The absorbed heat becomes the latent heat of the refrigerant, and although the temperature does not rise much, the internal energy increases a lot. Because the pressure changes very little, it is thermodynamically called an isobaric process.

Air energy dryerAlthough it cannot be compared with the "zero power consumption" of solar drying, it has the same advantages in energy saving. The use of refrigerant to absorb air can be heated, and electrical energy is only used as a driving device to run. The heating efficiency can reach 400, which is higher than that of coal-fired heating, and 75% energy saving than pure electric heating equipment. Every drying time to save a part of electricity, add up to a very considerable number, which is undoubtedly a good guarantee of business profits.

Air energy dryerUsing the principle of reverse Carnot cycle, using a small amount of electric energy, the compressor absorbs a large amount of heat energy in the air. After passing through the expansion valve, the working fluid evaporates into a gaseous state in the evaporator, and then is compressed into a high-temperature and high-pressure gas by the compressor, and then enters the condenser to release heat. Heating and drying medium, so as to continuously circulate heating. Compared with the hair dryer, it saves 2/3 of electricity.

Air energy dryerThe host is a high-temperature heat pump drying equipment, which is an energy lifting device. It uses the inverse Carnot principle to absorb heat from the surrounding environment and transfer it to the heated object. Its working principle is just the opposite of the refrigerator. The air energy heat pump dryer adopts advanced dehumidification heat pump technology, which saves more than 40% of energy. One kilogram of water is dehydrated from the material, which consumes about 0.25 per cent of electricity and can save more than 60 per cent of energy in off-peak power consumption mode. At present, the full-automatic dryer is an integrated drying and dehumidification integrated machine, which adopts air energy heating and drying technology, combined with condensation dehumidification + intelligent temperature control system, and the actual use effect is good.
