る事を特徴とする、冷凍機の運転制御方法。 In a heat recovery type air-cooled heat pump chiller unit, in addition to the outlet thermostat installed on the cold (hot) water outlet side to prevent freezing, there is also a two-stage thermostat on the cold (hot) water inlet side and a single-stage thermostat on the outlet side. When the cold water inlet water temperature drops and the second stage contact of the inlet side thermostat operates, and when the first stage of the inlet side thermostat operates and the cold water outlet side thermostat contact When activated, the system switches from simultaneous cooling and heating operation (heat recovery operation) to independent heating operation. Similarly, on the hot water side, when the hot water inlet water temperature rises and the second stage contact of the inlet side thermostat is activated, and when the first stage contact of the inlet side thermostat is activated and the hot water outlet side thermostat is activated. A refrigerating machine operation control method characterized by switching from simultaneous cooling and heating operation (heat recovery operation) to independent cooling operation when a contact is activated.
