Abstract
An air conditioning system has a refrigeration system that supplies a refrigerant to an evaporator coil enclosed in a chiller tank. A low temperature coolant in the chiller tank is then refrigerated by the evaporator coil. The coolant is then pumped from the chiller tank through a spiral wall pipe in an area to be air conditioned, removing heat by conduction, convection, and evaporative cooling, and returned to the chiller tank to be cooled and recirculated. The coolant in the chiller tank is maintained at a desired temperature by the refrigeration system. The temperature in the conditioned area is controlled by the temperature and flow of the coolant in the spiral wall pipe. A heating system supplies hot water to the above air conditioning system while bypassing the refrigeration system. Humidification and cleaning are achieved by an overhead pipe which is perforated, and water or cleaning solution is pumped under low pressure and dispersed down onto the spiral wall pipe. Residue water or cleaning solution is then carried away by a condensate channel located under the spiral wall pipe.
