Abstract:
A dehumidifying apparatus comprising:a moisture adsorbing device for removing moisture from process air and for being regenerated by desorbing moisture therefrom with regeneration air; and a heat pump having a condenser for condensing a refrigerant to heat said regeneration air at the upstream side of said moisture adsorbing device, an evaporator for evaporating said refrigerant to cool said regeneration air to a temperature equal to or lower than its dew point at the downstream side of said moisture adsorbing device, a pressurizer for raising a pressure of said refrigerant evaporated by said evaporator and delivering said refrigerant to said condenser, and a first heat exchanger for exchanging heat between said regeneration air flowing between said moisture adsorbing device and said evaporator and the regeneration air flowing between said evaporator and said condenser; wherein said regeneration air is used in circulation.
