Heat pump type low-temperature regeneration rotating wheel fresh air dehumidifier system

Abstract

The invention relates to a heat pump type low-temperature regeneration rotating wheel fresh air dehumidifier system. The system comprises a rotating wheel dehumidification unit, a heat pump unit, a fresh air duct and a regeneration air duct, wherein the fresh air duct and the regeneration air duct are separated from each other; the rotating wheel dehumidification unit comprises a dehumidification rotating wheel (18) used for heating and dehumidifying air; the dehumidification rotating wheel (18) is inserted into the fresh air duct and the regeneration air duct at the same time; the heat pump unit comprises a condenser (20) used for heating air in the regeneration air duct, and a heat exchanger (30) connected in sequence; the first evaporator (16) is used for recycling heat in the regeneration air duct; the inverter compressor (1) is used for providing steam for the condenser (20); and the condenser (20) and the first evaporator (16) are positioned in the regeneration air duct. Compared with the prior art, the dehumidification device has the advantages of being better in dehumidification capacity, lower in energy consumption, capable of achieving heat transfer and the like.

Description

technical field [0001] The invention relates to the field of wheel dehumidification technology, in particular to a heat pump type low-temperature regenerative wheel fresh air dehumidifier system. Background technique [0002] Rotary wheel dehumidification 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 runner can absorb the moisture in the humid air flowing through the runner, and the runner after moisture absorption can be dehydrated and regenerated by the high-temperature dry air. [0003] The regeneration air heater in the current rotary dehumidifier needs to heat the air to 120-140°C to vaporize the moisture absorbed by the moisture absorption rotor, and the heat absorbed by the moisture vaporization is discharged to the atmosphere together with the regeneration air, causing A waste of resources. The current rotary dehumidifier has ...

Problems solved by technology

[0003] The regeneration air heater in the current rotary dehumidifier needs to heat the air to 120-140°C to vaporize the moisture absorbed by the moisture absorption rotor, and the heat absorbed by the moisture vaporization is discharged to the atmosphere together with the regeneration air, causing waste of resources

The current rotary dehumidifier has the disadvantages of high regeneration energy consumption and waste of resources, so the rotary dehumidifier fresh air unit is rarely used in the air conditioning fresh air system of civil buildings
