Embodiment Construction
[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0018] see figure 1 , a heat pump type air conditioner heating mode control method, the air conditioner adopts the structure of the commonly used prior art, such as the Chinese patent application number 201010301015.3 cited in the background technology, including an outdoor unit and an indoor unit, the outdoor unit is installed with The four-way valve that adjusts the circulation direction of the refrigerant, the compressor that compresses the refrigerant and converts the refrigerant into a high-temperature and high-pressure refrigerant, electric heaters, condensers, and outdoor fans; indoor units include indoor fans, etc. The heat exchanger performs heat exchange, and the air conditioner also includes a controller.
[0019] Control method of the present invention comprises the steps:
[0020] 1) The air conditioner receives the heating star...

The invention discloses a heating mode control method of a heat pump air conditioner. The heating mode control method comprises the following steps that 1) the middle temperature Tcm of an outdoor condenser is measured firstly after the air conditioner receives a heating start command; 2) if it is detected that Tcm is higher than 0 DEG C or a set value, a compressor, a four-way valve coil, an indoor fan and an outdoor fan of the air conditioner are powered on to be started, and the air conditioner runs in a normal refrigerant compression and heating mode; 3) if it is detected that Tcm is no higher than 0 DEG C or the set value, an electric heating device and the indoor fan of the air conditioner are powered on to work, and the air conditioner runs in an electric heating and air supply heating mode; afterwards, if the air conditioner meets the preset mode switching conditions, the electric heating device is shut down, but the indoor fan continues running; the compressor, the four-way valve coil and the outdoor fan are powered on while the electric heating device is powered off, and the air conditioner runs in the normal refrigerant compression and heating mode; and otherwise, the air conditioner continues running in the electric heating and air supply mode till the mode switching conditions are met.
Description
technical field [0001] The invention relates to air conditioning control, in particular to a heating mode control method of a heat pump air conditioner. Background technique [0002] At present, the heat pump type through-the-wall unit with electric heating function sold on the market generally controls the start and stop of the compressor and the electric heater during the heating operation according to the temperature in the middle of the outdoor condenser when the unit is running in the heating mode. [0003] The general practice is that when the unit receives the heating start command, the controller detects the temperature in the middle of the outdoor condenser. When the temperature is lower than 0°C or a certain set value, the unit prohibits the compressor, four-way valve, and outdoor motor from starting. , the indoor side electric heating and fan start, the unit will heat according to the "indoor side electric heating wire dry heating + air cooling" method; when the t...
