  • Regenerative type air conditioning equipment
    Patent number: 5285645
    Abstract: A regenerative type air conditioning equipment in which the available concentration range of a heat accumulating liquid is widened, and the quantity of the heat accumulating liquid to be stored is decreased, so that the size of the equipment is reduced, with the conditioning equipment comprises a concentration difference regeneration device which, at least, cools a medium fed to an air conditioner, using a condensate liquid and a concentrated liquid produced by vaporizing the heat accumulating liquid, and a heat pump device which cools a coolant due to adiabatic expansion. The concentration difference regeneration device includes a container with a chamber for storing the condensate liquid, a spray nozzle which sprays the condensate liquid into the condensate liquid chamber, and an evaporator which vaporizes the sprayed condensate liquid under a low pressure.
