A solution dehumidification unit

Abstract

The invention provides a liquid dehumidification unit applied to the field of heating and ventilating air conditionings and aims to achieve low-pressure normal-temperature regeneration of concentrated liquids. The liquid dehumidification unit comprises a vacuum boiling evaporation chamber, a concentrated liquid pump, a gas-liquid separator, an evaporation chamber vacuum pump, an evaporation chamber vacuum gauge and a control circuit. A condensate collecting tray and a dilute liquid sprayer are disposed within the vacuum boiling evaporation chamber. The bottom of the vacuum boiling evaporation chamber is provided with a concentrated liquid outlet which is connected with the concentrated liquid pump; the control circuit controls the concentrated liquid pump to start or stop. A liquid inlet of the dilute liquid sprayer penetrates the vacuum boiling evaporation chamber to be connected with the gas-liquid separator. The evaporation chamber vacuum pump is communicated with the inside of the vacuum boiling evaporation chamber. The evaporation chamber vacuum gauge is used for detecting interior pressure of the vacuum boiling evaporation chamber. The evaporation chamber vacuum gauge transmits an evaporation chamber pressure detection signal to the control circuit; the control circuit controls the evaporation chamber vacuum pump to start or stop, according to the evaporation chamber pressure detection signal.

Description

technical field [0001] The invention relates to a solution dehumidification unit, in particular to a solution dehumidification unit applied to HVAC. Background technique [0002] The country strongly advocates energy saving and emission reduction, and the energy consumption of HVAC accounts for about 60% of building energy consumption, so the energy saving of HVAC occupies an absolute position in building energy conservation. The use of an independent temperature and humidity control system can greatly improve the efficiency of the air-conditioning host, thereby reducing building energy consumption. The temperature and humidity independent control system has been successfully used in practical engineering applications. The implementation process is to separate the sensible heat and latent heat. The sensible heat is processed by the high-temperature cold water host, and the latent heat is processed by the solution dehumidification equipment. The core of solution dehumidifica...
