Abstract

The invention discloses a heat pump driving solution moisture regulating and domestic hot water preparing system realizing energy balance. The system is characterized by comprising a heat pump circulating system and a solution moisture regulating system, the heat pump circulating system comprises a frequency-variable compressor, a four-way reversing valve, a solution cooling condenser, a stop valve, a throttling valve and an evaporator, and a water-cooling condenser is introduced to prepare domestic hot water; the solution moisture regulating system comprises a dehumidifier, a regenerator, a solution pump, a solution heat exchanger, a solution valve and a fan. The heat pump driving solution moisture regulating and domestic hot water preparing system combines a solution circulating system, the heat pump system and a domestic water preparing system, and domestic water is prepared by utilizing redundant condensing heat of a refrigerant while solution moisture regulating is realized through driving of a heat pump, so that system energy balance and effective utilization of energy resources are realized, and comprehensive performance of the system is improved.

Description

technical field [0001] The invention relates to a heat pump driven solution humidity control and domestic hot water production system realizing energy balance, belonging to the technical category of solution dehumidification and the field of domestic hot water production by condensation heat of the heat pump system. Background technique [0002] The use of solution dehumidification technology can use low-grade heat sources to realize independent treatment of air heat and humidity, and its advantages in energy saving have been recognized. Coupled with its good environmental acceptability and the advantages of helping to improve indoor air quality, solution dehumidification systems and air-conditioning systems based on solution dehumidification technology have received extensive attention in recent years. [0003] When there is no directly available waste heat with suitable temperature and grade to meet the demand for solution regeneration, a heat pump-driven solution humidity...
