Heat pump regulating apparatus for heating system, has free cooler cooling water return temperature to specific degree via water-water heat exchanger, and regulator switching off heater if external temperature rises to specific degree

摘要

The apparatus has a heat pump (10) into which process cooling water is fed via a pipe, where pump delivers heat energy to a heat exchanger. A regulator (90) sends a signal to a free cooler pump, if water return temperature rises up. A free cooler cools down the return temperature to a specific degree via a water-water heat exchanger, and a heater is switched off by a regulator (94), when external temperature rises to specific degree.
