The invention discloses a composite running mode control method of a heat recycling type air conditioning unit. The composite running mode control method comprises the following steps of setting a preferential running status to determine a status switching range; detecting water temperature values of an air conditioning side and a hot water side of the heat recycling type air conditioning unit; determining startup and shutdown requirements of the air conditioning side and the hot water side according to the preset startup and shutdown conditions and the detected water temperature values; switching the running status of the heat recycling type air conditioning unit in the status switching range according to the determined startup and shutdown requirements. According to the composite running mode control method, no matter which running status the air conditioning unit runs, the air conditioning unit always meets requirements of a priority state, which are defined by the user, when the application requirements corresponding to the priority state completely meet shutdown of the air conditioning unit, setting and switching of the composite running mode of the air conditioning unit are human-friendly and reasonable, and waste of energy is reduced; automatic switching of the running status is implemented, and complexity for switching is reduced. The invention further discloses the heat recycling type air conditioning unit applying the control method.
Description
technical field [0001] The present application relates to the technical field of air-conditioning control, in particular to a heat recovery type air-conditioning unit and a method for controlling the combined operation mode thereof. Background technique [0002] There are five common operating modes of heat recovery air-conditioning units, including three single modes (cooling mode, heating mode and hot water mode) and two composite modes (cooling and heating water mode and heating and heating mode). hot water mode). In the compound mode, the air conditioning unit will appear in various operating states according to the load change. Existing air-conditioning units can only choose to operate in various operating states according to the on-off requirements of the air-conditioning side and the hot water side, but cannot selectively operate according to the actual needs of users. [0003] For example, in the cooling and hot water heating mode, during the actual operation of th...
