The invention discloses a control method of an outdoor fan in a heat recovery air conditioning and water heating unit. The control method includes the following steps that the environment temperature is obtained, and the operating current of a compressor is obtained; when the heat recovery air conditioning and water heating unit operates in a refrigeration heat recovery mode, whether the environment temperature is higher than a preset temperature is judged; and if it is judged that the environment temperature is higher than the preset temperature, the outdoor fan is controlled according to the operating current of the compressor. According to the control method of the outdoor fan in the heat recovery air conditioning and water heating unit, through intelligent control over the outdoor fan, electric energy waste can be reduced, the overall noise of an outdoor unit is lowered, and the energy saving and comfort effects are good. The invention further discloses the heat recovery air conditioning and water heating unit.
Description
Technical field [0001] The invention relates to the technical field of air-conditioning water heaters, in particular to a method for controlling an outdoor fan in a heat recovery air-conditioning water heater and a heat recovery air-conditioning water heater. Background technique [0002] At present, most of the heat recovery air conditioner water heaters are inverter multi-unit air conditioner water heaters, which generally use inverter compressors. The heat recovery air conditioner water heaters are not only energy-saving, but also can produce free domestic water while cooling in summer. Among them, from the perspective of the refrigeration system cycle, when the system is in heat recovery mode, the indoor unit acts as an evaporator, and the heat exchanger of the outdoor unit does not flow through the heat exchanger. From the perspective of refrigerant heat exchange, the fan of the outdoor unit can be turned off . [0003] However, because the electronic control components such ...
