Abstract

The invention relates to an internal-cooled solution dehumidifying assembly. The internal-cooled solution dehumidifying assembly comprises at least one group of solution dehumidifying units, at least one group of solution regeneration units, and at least one group of solution heat recovery units; the solution dehumidifying unit is provided with a first solution spraying device, a first heat exchange device and a first solution box orderly from top to bottom; the solution regeneration unit is provided with a second solution spraying device, a second heat exchange device and a second solution box orderly from top to bottom; the solution heat recovery unit comprises an upper heat recoverer and a lower recoverer, the two of which are the same in structure. A solution dehumidifying regeneration cycle loop is arranged between the solution dehumidifying unit and the solution regeneration unit, while a solution heat recovery cycle loop is arranged between the upper heat recoverer and the lower recoverer; the first heat exchange device and the second head exchange device are of an internal-cooling or internal-heating heat exchange mode. The internal-cooled solution dehumidifying assembly has the advantages of stable system, low manufacturing and operating costs, high energy efficiency ratio and accurate control.

Description

technical field [0001] The invention relates to dehumidification equipment in the field of air conditioning, in particular to an internal cooling solution dehumidification unit. Background technique [0002] In the field of air conditioning, it is usually necessary to cool and dehumidify the incoming outdoor air in summer, and to heat and humidify the incoming outdoor air in winter. Most of the traditional air-conditioning systems use condensation dehumidification treatment, that is, use a refrigerator to prepare low-temperature chilled water, and circulate the chilled water in the coil of the surface cooler and exchange heat with the air to reduce the air temperature below the dew point. In this way, the air condenses to dehumidify the fresh air. The dehumidification and cooling process of this treatment method are controlled as one and carried out at the same time. Since the chilled water temperature required for dehumidification is much lower than the chilled water tempe...
