Embodiment

[0040] The refrigeration and dehumidification switching method of the air conditioner described in the embodiment of the present invention, such as figure 1 shown, including the following steps:

[0041] Step S1. After the air conditioner switches between cooling mode and dehumidification mode, calculate the adaptation of the electronic expansion valve according to the opening of the electronic expansion valve before the mode switching, and the compressor frequency, indoor fan speed and outdoor fan speed before and after the mode switching opening;

[0042]Wherein, the switching of the air conditioner between the cooling mode and the dehumidification mode includes the switching of the air conditioner from the cooling mode to the dehumidification mode, and the switching of the air conditioner from the dehumidification mode to the cooling mode.

[0043] like figure 2 As shown, the calculation method of the adaptive opening degree of the electronic expansion valve after the ai...

Abstract

The invention relates to the technical field of air conditioners. The invention aims to solve the problem of poor cooling or dehumidification effects caused by the mismatch of refrigerant flow when the existing air conditioners switch modes between cooling and dehumidification, and proposes a method for switching cooling and dehumidification of air conditioners , including the following steps: when the air conditioner is switched between the cooling mode and the dehumidification mode, calculate the electronic expansion valve opening according to the opening of the electronic expansion valve before the mode switching, and the compressor frequency, the indoor fan speed and the outdoor fan speed before and after the mode switching Adaptive opening; adjust the electronic expansion valve according to the adaptive opening, and the electronic expansion valve is used to control the refrigerant flow. According to the opening degree of the electronic expansion valve before the mode switching, the change of the frequency of the compressor and the change of the speed of the indoor and outdoor fans, the present invention adjusts the electronic expansion valve to the appropriate opening degree, realizes the control of the refrigerant flow rate, and makes the current operation mode of the air conditioner consistent with the refrigeration mode. The agent flow is matched, which improves the cooling and dehumidification effect of the air conditioner. Suitable for inverter air conditioners.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a cooling and dehumidification switching method and system. Background technique [0002] Inverter air conditioners often switch between switching modes during use, such as switching between cooling, heating, and dehumidification. Since the flow directions of heating and cooling / dehumidifying refrigerants are opposite, it is necessary to switch the four-way valve. Therefore, heating and cooling When switching between refrigeration and dehumidification, it will stop to balance the pressure and then switch modes. In this process, the electronic expansion valve will automatically match the appropriate refrigerant flow opening for the corresponding mode before switching modes. However, when switching between cooling and dehumidification, due to refrigerant The flow direction does not change, so the mode can be switched directly without stopping the machine. [0003] However...
