Cooling-water return temp. regulating type dehumidifier

The utility model relates to a cooling-water wind return temperature regulation type dehumidifier, which comprises a compressor, an evaporator and a condenser which have head-to-end connection, wherein the condenser comprises a wind cooling condenser and a water cooling condenser which are connected together in parallel, the wind cooling condenser and the water cooling condenser which are connected in parallel are connected with the position between the compressor and the evaporator in series, pipelines of the wind cooling condenser and the water cooling condenser are respectively provided with an electromagnetic valve which controls the on-off state of each pipeline, and the electromagnetic valve arranged in the pipeline of the wind cooling condenser is interlocked with the electromagnetic valve of the water cooling condenser mutually. The dehumidifier is provided with a temperature sensor which is electrically connected with a main controller which controls the operation of the dehumidifier. The utility model adopts that the temperature sensor and two electromagnetic valves interlocked mutually control different heat exchangers to work respectively. The utility model is suitable for the operating conditions of wind inlet dry ball temperature range of 18-32DEG. C and relative humidity of 40%-90%. The utility model not only has constant temperature dehumidification, but also has warming-up dehumidification, and the utility model can control air return temperature accurately.
