Abstract:
A separated type air conditioner with evaporative condensing apparatus comprises:an outdoor unit, at least one indoor unit, and a chilled water circulation piping system connected between said outdoor unit and each of said indoor unit for cooling capability transmission; which said outdoor unit comprises: an evaporative condensing apparatus including a plurality of medium condensing coils formed a plurality of air gaps thereat, a layer of absorptive material covered over all heat conductive surfaces of said condensing coil thereon, an evaporative water supply system having a plurality of water distributors and an electromagnetic valve for intermittently spraying water to said absorptive material hereon, a fan system to draw currents of air passing through said air gaps between said condensing coils for speeding the rate of evaporating of absorbed water in said absorptive material and carrying the evaporated moisture and heat away from said evaporative condensing apparatus, a PC board automatically controlling an open/close operation of said electromagnetic valve therefore; an evaporating apparatus formed of a medium/water heat exchanger type water chiller in which a water flow is chilled due to cooling medium evaporating and be transmitted to each of said indoor unit for using as a cooling source therefore; and a cooling medium circulating system including a medium compressor for compressing gas state cooling medium into said evaporative condensing apparatus to condense cooling medium into liquid state, a liquid medium piping for guiding condensed medium from said evaporative condensing apparatus to said evaporating apparatus, an expansion valve disposed at a medium inlet of said evaporating apparatus for evaporating liquid state cooling medium into gas state in said evaporating apparatus to produce chilled water thereat, a gas medium piping for guiding evaporated medium back to said compressor from said evaporating apparatus so as to complete a medium circulating system therefore; while each of said indoor unit is formed of a water/air heat exchanger to cool air currents by chilled water delivered from said water chiller type evaporating apparatus of said outdoor unit, in which the room temperature will be dropped by cooled air currents therefore; and said chilled water circulating system circulated between said water chiller type evaporating apparatus of said outdoor unit and said heat exchanger type indoor unit compressing a water pump disposed in said outdoor unit, a chilled water delivering piping with pipe fittings for delivering chilled water to each of said indoor unit from said water chiller of said outdoor unit, and a water feedback piping with pipe fittings for guiding heated water back to said water pump after heat exchanging in said indoor unit so as to complete a water circulating system therefore.
