Evaporative condensing apparatus

摘要

An evaporative condensing apparatus used in an air conditioner to reduce the power consumption of the condenser and improves its EER value. The evaporative condensing apparatus is based on the rule that the relative critical pressure needed to condense a cooling medium is directly proportional to the temperature during the exchange of a cooling medium between gas state and liquid state. The evaporative condensing apparatus includes an evaporative condensing unit for condensing a gas state cooling medium into a liquid state, having a plurality of condenser coils and a layer of absorptive material covered on the condenser coils, a low compressor controlled to compress a gas state cooling medium into a liquid state in the evaporative condensing unit, an intermittent water supply system having a control PC board and an electromagnetic valve controlled by the control PC board to let cooling water be delivered from a water source to the layer of absorptive material of each condenser coil, and a condenser fan controlled to draw currents of air through gaps in the condenser coils of the evaporative condensing unit in carrying heat away from the evaporative condensing unit.
