Abstract:
An evaporative condensing apparatus comprising:an evaporative condensing unit for condensing a gas state cooling agent into a liquid state, said evaporative condensing unit comprising a plurality of condenser coils having absorptive means covered thereon;a low compression ratio compressor controlled to pump the gas state cooling agent into said evaporative condensing unit;a water supply system having a control PC board and an electromagnetic valve controlled by said control PC board to deliver cooling water from a water source to the layer of absorptive material of each of said condenser coils of said evaporative condensing unit; and,a condenser fan having a fan motor and a fan blade unit driven by said fan motor to draw currents of air through gaps in the condenser coils of said evaporative condensing unit for carrying heat away from said evaporative condensing unit;said control PC board of said water supply system including a selector switch for high, medium and low water pressure selections, said control PC board operating said electromagnetic valve in coordination with operation of said low compression ratio compressor to periodically supply water to said evaporative condensing unit in an amount approximately equal to an amount of water being evaporated.
