制御方式。 This is a heat recovery type chilled/hot water system consisting of a compressor, an air side heat exchanger, a cold water heat exchanger, a hot water heat exchanger, a pressure reducer, and auxiliary equipment.The operation mode is cooling operation with only cold water supplied, and hot water only supply. In addition to the supply heating operation, a heat recovery operation is performed to simultaneously supply cold water and hot water, and furthermore, a defrosting operation is performed to remove frost attached to the air side heat exchanger. In hot water equipment,
A contact that controls defrosting operation and sends a signal to enter defrosting when the defrosting start temperature is reached after a certain period of time has elapsed, and a timer contact that controls not to enter defrosting operation for a certain period of time at the start of heating operation. A defrosting control system for a heat recovery type water chiller/heater device, which is characterized by having two in series.
