Abstract:
A refrigeration system in which water is evaporated to generate cold heat and water vapor produced is increased in pressure by pressure increasing means (50) and then discharged,wherein said pressure increasing means is driven at least by mechanical power derived from thermal energy; the refrigeration system further comprises: cold heat generating means in which water serves as a refrigerant; said water is evaporated to generate cold heat; and water vapor produced is drawn into said pressure increasing means; moisture discharging means for discharging water vapor increased in pressure by said pressure increasing means; a prime mover for generating mechanical power from thermal energy to drive said pressure increasing means; wherein said cold heat generating means comprises a humidification cooler which supplies water to air to be conditioned so that said air is cooled, and a dehumidifier which dehumidifies said air cooled by said humidification cooler, and wherein said dehumidifier includes a water vapor permeable membrane allowing water vapor to pass therethrough so that water vapor can be removed because of a difference in water vapor pressure created between partition spaces divided by said water vapor permeable membrane.
