Problems solved by technology
[0004] It can be seen that the current indoor heat exchanger control method can only improve the effect of the cooling mode or the heating mode. For example, when the indoor heat exchanger is controlled in the cooling mode, the refrigerant flow direction is opposite to the air flow direction, and in the heating mode, the refrigerant flow direction is controlled. Same direction as air flow, resulting in 200W increased capacity in cooling mode and 600W reduced capacity in heating mode
The current indoor heat exchanger control method cannot improve the effect of cooling and heating at the same time

The invention discloses a control method for an indoor heat exchanger, a controller, the heat exchanger and an air conditioner. The method comprises the steps that a current working mode of the air conditioner is detected; based on the detected working mode, a control instruction corresponding to the working mode is generated; and the control instruction is sent to an indoor heat exchanger so that based on the control instruction, the indoor heat exchanger can control a refrigerant inlet electromagnetic valve and a refrigerant outlet electromagnetic valve which are arranged on the indoor heat exchanger and correspond to a refrigerating mode, and can also control a refrigerant inlet electromagnetic valve and a refrigerant outlet electromagnetic valve which are arranged on the indoor heat exchanger and correspond to a heating mode. According to the indoor heat exchanger, the controller, the heat exchanger and the air conditioner, the refrigerant inlet electromagnetic valve and the refrigerant outlet electromagnetic valve corresponding to the refrigerating mode and the refrigerant inlet electromagnetic valve and the refrigerant outlet electromagnetic valve corresponding to the heating mode are arranged on the indoor heat exchanger, based on the current working mode of the air conditioner, the refrigerant inlet electromagnetic valve and outlet electromagnetic valve are controlled to be opened or closed, and therefore the flow directions of refrigerant in the refrigerating mode and the heating mode can be opposite to the flow direction of air, and the heat exchange efficiency can be improved.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to an indoor heat exchanger control method, a controller, a heat exchanger and an air conditioner. Background technique [0002] An air conditioner is an air conditioner, also referred to simply as an air conditioner, which is used to adjust and control parameters such as temperature, humidity, and cleanliness of indoor ambient air. An air conditioner usually consists of an indoor unit and an outdoor unit. [0003] At present, when the heat exchanger in the indoor unit of the air conditioner (referred to as the indoor heat exchanger) is in the cooling mode, if the flow direction of the refrigerant in the indoor heat exchanger is opposite to the air flow caused by the fan in the indoor unit (referred to as the indoor fan) ; then when the air conditioner is in the heating mode, the flow direction of the refrigerant in the indoor heat exchanger and the air flow caused by the ...
