Abstract

The invention discloses a solution dehumidifying unit and a method and a device for controlling the solution dehumidifying unit. The method comprises the following steps: an air return side heat recovery module is used for heating and humidifying moisture absorbing solution in the solution dehumidifying unit through returned air and obtaining reflux solution through collecting the moisture absorbing solution after heating and humidification; a fresh air side heat recovery module is connected with the air return side heat recovery module, and is used for heating and humidifying fresh air by using the reflux solution; and a solution spraying module is connected with the fresh air side heat recovery module, and is used for heating and humidifying the fresh air again by using the sprayed solution. The method solves the technical problem of crystallization or icing caused by lower concentration easily generated by solution of a solution dehumidifying unit under low-temperature operation conditions in the prior art.

Description

technical field [0001] The invention relates to the field of a solution dehumidification unit, in particular to a solution dehumidification unit, a method and a device for controlling the solution dehumidification unit. Background technique [0002] At present, in the severe cold regions of the north, the enthalpy value of fresh air in winter is very low, and the difference between the enthalpy of indoor exhaust air is relatively large, the load of fresh air is high, and the potential for heat recovery is huge. Solution dehumidification is to use the humidity control characteristics of some solutions to dehumidify (or humidify) the air. The temperature of the air treated with the solution is determined by the temperature of the solution, and the relative humidity is determined by the concentration of the solution. The use of solution heat recovery can realize full heat recovery, high heat recovery efficiency, and long-term operation without attenuation. [0003] Although t...
