Abstract
In a heat pump system including a water purifier and an evaporator for evaporating feed-water to produce steam, water used for spray cooling is effectively used and productivity of purified water used for the spray cooling is increased. Discharged water from the water purifier is supplied to the evaporator when water used for spray cooling is produced by use of the water purifier. Otherwise, drain of the evaporator having higher temperature is supplied to the water purifier by using such a fact that in a reverse osmosis membrane type water purifier, the higher the temperature of feed-water is, the higher the purified water productivity becomes.
Claims1
A heat pump system comprising:
- a water purifier;
- an evaporator for evaporating feed-water to produce steam;
- a compressor for compressing the steam produced by the evaporator, and supplying the compressed steam;
- and
- a supply system used to supply discharged water from said water purifier to said evaporator,
- wherein the water purifier converts a portion of raw water into purified water and discharges a remainder of the raw water as discharged water, and
- the heat pump system further comprising:
- a humidifying device for humidifying steam supplied to the compressor by using purified water from said water purifier;
- and
- trap means for removing impurities from the discharged water from said water purifier to said evaporator.
