The invention relates to the technical field of air conditioners, in particular to an anti-freezing control method of a heat pump unit, and solves the problem that an existing anti-freezing control method of a heat pump unit is too simple, and is low in control precision. The anti-freezing control method of the heat pump unit comprises the following steps: acquiring the outdoor environment temperature; selectively acquiring the water inlet temperature of a water circulation system according to the outdoor environment temperature; and judging whether an anti-freezing control mode is started ornot based on the outdoor environment temperature and the water inlet temperature. The condition that whether the anti-freezing mode is started or not is judged on the basis of the outdoor environmenttemperature and the water inlet temperature of the water circulation system, so as to achieve precise anti-freezing control of the heat pump unit and further effectively prevent damage of a heat exchanger due to freezing.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to an anti-freezing control method for a heat pump unit. Background technique [0002] The air-cooled heat pump unit uses air as the cold (heat) source, and uses the refrigerant as the cooling medium to exchange heat with water. The cooled (heated) water provides cold (heat) for the required area through secondary heat exchange. The air-cooled heat pump unit is gaining market share due to its advantages of energy saving, environmental protection, flexible combination, and convenient installation. It provides cold water to the air-conditioning system in the cooling season and hot water to the air-conditioning system in the heating season. It is an ideal air-conditioning cold and heat source. . [0003] In the winter heating mode, the air conditioner is in standby mode after reaching the heating temperature, and both the compressor and the water pump are in the off state. T...
