The dehumidification rotating wheel (12) is simultaneously inserted into the fresh air duct and the regeneration air duct. The direct expansion unit comprises an air-cooled condenser (22) used for heating air in the regeneration air duct; an evaporator (23) used for recycling heat in the fresh air duct; and an inverter compressor (21) used for providing steam for the air-cooled condenser (22), wherein the air-cooled condenser (22) is located in the regeneration air duct, the evaporator (23) is located in the fresh air duct, the air-cooled condenser (22), the evaporator (23) and the inverter compressor (21) are sequentially connected. Compared with the prior art, the heat pump type low-temperature regeneration rotating wheel fresh air frequency conversion dehumidification system has the advantages of energy conservation, high efficiency, higher dehumidification capacity and the like.
Description
technical field [0001] The invention relates to the technical field of rotary dehumidifiers, in particular to a heat pump type low-temperature regenerative rotary fresh air frequency conversion dehumidification system for radiant air conditioners. Background technique [0002] The rotary dehumidifier belongs to an important branch of the air conditioning field and is a typical representative of heating dehumidification. The main component of the rotary dehumidifier is the runner. The surface of the runner is coated with a hygroscopic agent, and the surface is provided with honeycomb porous channels. The runner can absorb the moisture in the humid air flowing through the runner. After the moisture is absorbed, the runner is blown by high-temperature dry air to dehydrate and regenerate the moisture absorbent. The regeneration air heater in the current runner dehumidifier requires A large amount of energy is consumed to heat the regeneration air to vaporize the moisture absorbe...
