Abstract
The invention provides a dehumidification system and dehumidification method for hot-gas recycle and secondary cooling for a washing machine room. Domestic hot water supply is a necessary service way in a university. Most of hot water is provided by coal-fired boilers or gas-fired boilers, and energy resources are consumed a lot. Used waste water and used waster gas are directly thrown away, a great amount of heat energy and water resources are wasted, meanwhile, environment is polluted, heat energy is taken away without being used after waste water and waste gas of an ironer in the washing machine room are discharged, and waste and heat pollution are caused. The dehumidification system for hot-gas recycle and the secondary cooling for the washing machine room comprises a washing room (1) and a heat exchanger unit system (2), a waste heat pipe (8), washing machines (11) and a dehumidifier (5) are arranged in the washing room, a waste gas exchanger (3) and a condenser (7) are arranged in the waste heat pipe, the heat exchanger unit system is provided with a heat exchanger unit (6), and the heat exchanger unit and the waste gas exchanger form a circulation loop. The dehumidification system and dehumidification method for hot-gas recycle and the secondary cooling for the washing machine room are applied to hot gas recycle and utilization.
