Description

technical field [0001] The invention relates to a dehumidification air-conditioning system, in particular to a multi-energy complementary drive dehumidification air-conditioning system, which belongs to the technical field of building energy-saving engineering applications. Background technique [0002] The solution dehumidification technology uses a salt solution with dehumidification function (such as LiCl, CaCl2, LiBr, etc.) as the working medium, and uses the moisture absorption and dehumidification characteristics of the solution to adjust and control the air humidity. The water vapor partial pressure difference between the salt solution and the air is the driving force for water transfer between the two. When the surface vapor pressure of the solution is lower than the water vapor partial pressure in the air, the solution absorbs the water in the air and the air is dehumidified; otherwise, The moisture in the solution enters the air, the solution is concentrated and re...

The Chinese patent (application) number is CN200820160676.7, and the name is solution dehumidification air-conditioning equipment using membrane regenerator, which discloses a solution dehumidification air-conditioning equipment using membrane regenerator. The solution regeneration of solution dehumidification air-conditioning equipment adopts ion exchange membrane , the positive and negative ions in the dilute solution are collected separately and mixed to form a new concentrated solution. The introduction of the ion exchange membrane realizes the regeneration of the dehumidification solution at room temperature, avoiding a large amount of energy loss caused by high temperature regeneration, but the regeneration of the dehumidification solution using the ion exchange membrane requires consumption Electric energy, and there is a great potential safety hazard

The Chinese patent (application) number is CN201010587750.5, and the name is a multi-stage M-shaped air channel solution dehumidification air-conditioning system using ultrasonic atomization technology. Atomization, the humid air to be treated fully contacts with the atomized salt solution particles in the dehumidification air-conditioning box for heat and mass exchange. Compared with the traditional packing dehumidification air-conditioning system, the biggest advantage is that the building space utilization rate is large and the system resistance is small. At the same time Increase the gas-liquid contact area and the gas-liquid reaction time to improve the dehumidification efficiency of the solution, but the use of ultrasonic atomized dehumidification solution to dehumidify the air will increase the problem of liquid in the treated air, which will deteriorate the indoor air quality and not only affect the normal operation of indoor electrical equipment , may also have a negative impact on human health
