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.
