Description

technical field [0001] The invention relates to dehumidification equipment in the field of air conditioning, in particular to a ground source heat pump type dual cold source solution dehumidification unit. Background technique [0002] In the field of air conditioning, it is usually necessary to cool and dehumidify the incoming air in summer, and it is usually necessary to heat and humidify the incoming air in winter. Most of the traditional air-conditioning systems use condensation and dehumidification treatment, that is, a refrigerator is used to prepare low-temperature cooling water, and the cooling water circulates in the coil of the surface cooler to exchange heat with the air to reduce the air temperature to below the dew point, thereby reducing the air temperature. Dehumidify the fresh air by condensing moisture out of the air. The dehumidification and cooling processes of this treatment method are controlled and carried out simultaneously. Since the temperature of t...
