Solution fresh air system based on reverse osmosis membrane solution regeneration and control method thereof

Abstract

A solution central ventilation system based on reverse osmosis membrane solution regeneration and a control method thereof relate to a central ventilation processing method which utilizes solution to treat fresh air of an air conditioner to realize energy recovery and simultaneously uses a reverse osmosis membrane to do solution regeneration, and a device used for realizing the method. When the central ventilation system of the air conditioner in the building is turned on in summer, the solution central ventilation system based on reverse osmosis membrane solution regeneration runs, outdoor fresh air in a first air loop enters a first dehumidifier and has heat and moisture transfer with the solution; after being treated by dehumidification, the fresh air goes out of the first dehumidifier and then enters a heat recoverer to do heat interchange with indoor discharge air; the temperature of the fresh air is lowered and enters a surface cooler after going out of the heat recoverer to do heat interchange with chilled water, so that the temperature of the fresh air is further reduced; when being treated to be a blowing-in state, the fresh air enter the room; the indoor discharge air enters a first heat interchanger to exchange heat with the solution, so as to absorb heat, cool the solution and raise the temperature; then, the indoor discharge air enters the heat recoverer to exchange heat with the indoor fresh air; the fresh air is cooled, the temperature of the discharge air raises, and finally the discharge air is discharged outside the room.

Description

technical field [0001] The invention relates to a fresh air treatment method and a device for realizing the method, which use a solution to process air-conditioning fresh air to realize energy recovery, and use a reverse osmosis membrane to regenerate the solution, and belong to the technical field of refrigeration and air-conditioning system design and manufacture. Background technique [0002] With the development of the economy and the improvement of living standards, people have higher and higher requirements for the comfort of work and life. At the same time, with the gradual depletion of fossil energy, energy problems have become increasingly prominent. This puts forward higher requirements for air conditioning system, which is a large energy consumer: more comfortable, higher air quality, and energy saving at the same time. In order to ensure the air quality of the building's air conditioning system, the fresh air system has become an indispensable part, and to a cert...
