Description

Technical Field

[0001] The utility model relates to an energy-saving combined rotary dehumidifier which utilizes condensation heat recovery technology for regeneration and belongs to the field of indoor dehumidification. Background Art

[0002] Since the domestic rotary dehumidifier was introduced in my country in the 1970s, it has been widely used in product manufacturing and storage warehouses in building air conditioning, medicine, chemical industry, light industry, electronics and other industries, as well as in environments requiring low temperature and low humidity. In the basement distribution room of a hydroelectric power station, moisture can cause the high-voltage electrical circuit to have a risk of leakage. In places where the daily temperature changes dramatically, even objects placed on the ground in buildings, such as metals such as iron plates, will condense due to the temperature difference between their surface and room temperature, causing metal corrosion. In this case, only dry air can be sent in to prevent condensation. For comfort air conditioning systems, the use of rotary dehumidification air conditioning must be based on the technical support of reducing the energy consumption of rotary regeneration, or using waste heat or renewable energy (solar energy, etc.) for rotary regeneration. For example, patent CN201010104417.4 provides a small plate on a hygroscopic rotary wheel that can be powered on to complete the evaporation work when entering the evaporation area, thereby improving the dehumidification efficiency. However, it still uses high-grade energy and cannot achieve energy-saving effects.

[0003] In view of the above problems, the utility model is an energy-saving combined rotary dehumidifier which uses condensation heat recovery technology for regeneration, which makes full use of waste heat and greatly saves energy. Summary of the invention

[0004] The utility model provides an energy-saving combined rotary dehumidifier using condensation heat recovery technology for regeneration, which is mainly composed of: a first air filter 1, a first condenser 2, a heater 3, a regeneration fan 4, a compressor 5, a second condenser 6, an expansion valve 7, a second air filter 8, an evaporator 9, a blower 10, and a rotary wheel 11;

[0005] The outlet of the evaporator 9 is connected to the compressor 5, the first condenser 2, the second condenser 6, and the expansion valve 7 in sequence; the outlet of the expansion valve 7 is connected to the inlet of the evaporator 9; the first air filter 1 is connected to the heater 3 through the first condenser 2; the heater 3 is connected to the regeneration fan 4 through the rotor 11; the second air filter 8 is connected to the evaporator 9, and the air passing through the evaporator 9 is connected to the air blower 10 through the rotor 11.

[0006] In summer conditions, the air is filtered through the second air filter 8 and enters the evaporator 9. The refrigerant in the evaporator 9 evaporates and absorbs heat, lowering the air temperature. After being dehumidified by the rotor 11, the air is sent out by the blower 10. The regenerated air is filtered through the first air filter 1, condensed by the first condenser 2 to release heat, and the regenerated air temperature rises. It is heated by the heater 3, passes through the rotor 11, and is sent out by the regeneration fan 4. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] Attached Figure 1 It is the principle diagram of the utility model.

[0008] Attached Figure 1 The label names are: 1. first air filter, 2. first condenser, 3. heater, 4. regeneration fan, 5. compressor, 6. second condenser, 7. expansion valve, 8. second air filter, 9. evaporator, 10. blower, 11. rotor. DETAILED DESCRIPTION

[0009] like Figure 1 As shown, an energy-saving combined rotary dehumidifier using condensation heat recovery technology for regeneration mainly includes a first air filter 1, a first condenser 2, a heater 3, a regeneration fan 4, a compressor 5, a second condenser 6, an expansion valve 7, a second air filter 8, an evaporator 9, a blower 10, and a rotary wheel 11.

[0010] In summer conditions, after outdoor air is filtered by the second air filter 8, the temperature is reduced to 10-16°C after the refrigerant in the evaporator 9 evaporates and absorbs heat. After the air is dehumidified by the rotor 11, it is sent into the room by the blower 10. After the regeneration air is filtered by the first condenser 2, it is heated by the sensible heat in the first condenser 2, and then heated to 120°C by the heater 3, passes through the regeneration area of ​​the rotor 11, and is sent out by the regeneration blower 4. The refrigerant evaporates and absorbs heat in the evaporator 9, reducing the temperature of the outdoor air passing through the second air filter 8. The refrigerant passes through the compressor 5 and releases sensible heat in the first condenser 2, raising the temperature of the regeneration air passing through the first air filter 1. Then the refrigerant releases latent heat in the second condenser 6, passes through the expansion valve 7, and returns to the evaporator 9.

[0011] The utility model reheats the regenerated air based on the condensation heat of the cooling and dehumidifying part, realizes heat recovery, reduces energy consumption, and is energy-saving and efficient.
