The dehumidification solution wanted is higher.Solution concentration is higher, and regeneration temperature is higher.In heat-pump-type solution air-conditioning, regeneration temperature is direct
The condensation temperature of heat pump is influenceed, condensation temperature is higher, and the power consumption of heat pump is higher.Therefore, air-supply relative humidity is reduced, can be led
Cause the increase of unit power consumption, systematic energy efficiency ratio reduction.In summer, condensation temperature is too high, easily triggers delivery temperature protection, high pressure
The problems such as protection, influence the operation stability of system.If solution concentration is lowered, air-supply relative humidity is raised, water capacity
Reduce, moisture removal can reduce again.
