Abstract
Water is used as a refrigerant, and a humidification cooler (41) which evaporates the water to generate cold heat and a dehumidifier (42) are provided. A compressor (50) which compresses water vapor separated by the dehumidifier (42) is provided. A moisture discharging device (60) which discharges water vapor compressed in the compressor (50) is provided. The compressor (50) is driven by a steam turbine (80) capable of generating rotational power from thermal energy.
Claims16
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.
