Problems solved by technology

However, in this scheme, due to the lack of control over the temperature of the moisture-absorbing solution at the inlet of the dehumidification (regeneration) device, the device has a low ability to absorb moisture (concentrate and regenerate) the moisture-absorbing solution.

Abstract

The invention relates to the technical filed of heating ventilation air conditioning (HVAC), and particularly to a heat pump driven precooling and internal-cooling solution dehumidification air conditioning unit. The solution dehumidification air conditioning unit comprises a solution circulation system formed by an internal-cooling dehumidification module and an internal-heating regeneration module and a heat pump system, wherein the solution circulation system is an inter-stage solution circulation circuit formed by connecting a dehumidification spray device and a regeneration spray device through a solution circulation pump; the inter-stage solution circulation circuit is filled with a moisture absorption solution; and the heat pump system comprises a refrigeration circuit formed by connecting a dehumidification internal-cooling evaporator, a compressor, a regeneration internal-heating condenser and a throttle valve in sequence, a solution precooling heat exchanger used for precooling the solution at the inlet of the dehumidification spray device and a solution preheating heat exchanger used for preheating the solution at the inlet of the regeneration spray device. The heat pump driven precooling and internal-cooling solution dehumidification air conditioning unit integrates the characteristics of adiabatic and internal-cooling (heating) solution dehumidification devices, can control the temperature of the solution at the inlet of the dehumidification (regeneration) spray device, and can also improve the dehumidification (regeneration) capacity of the dehumidification (regeneration) spray device.

Description

technical field [0001] The invention relates to the technical field of heating, ventilating and air conditioning, in particular to a heat pump-driven precooling type internal cooling solution dehumidification air conditioning unit. Background technique [0002] At present, the main task of the air-conditioning system in civil buildings is to meet the comfort requirements of indoor personnel for temperature and humidity, and the air dehumidification process is one of the important links in creating an indoor temperature and humidity environment. Most of the existing air-conditioning dehumidification methods use condensation dehumidification treatment. The low-temperature chilled water prepared by the refrigerator is used to lower the air temperature below the dew point, so that the moisture in the air condenses to realize the dehumidification treatment process of the air. However, because the required condensation temperature is very low (lower than the dew point temperature ...
