Embodiment 1

[0072] The bypass throttling element of the air conditioning system is a solenoid valve.

[0073] Such as figure 2 As shown, the temperature detection device of the air conditioning system detects the temperature Tf of the electronic components, and transmits the detection signal to the controller, and the controller compares the temperature Tf with the first set temperature Ts1 and the second set temperature Ts2.

[0074] When Tf>Ts1, the controller can control the bypass throttling element to open and the outdoor throttling element to close. At this time, there is refrigerant circulation in the refrigerant heat dissipation part, and the refrigerant heat dissipation part and the air heat dissipation part simultaneously dissipate heat for electronic components, and the heat dissipation effect is good. , to avoid damage to electronic components caused by poor air convection heat dissipation alone.

[0075] When Tf

Embodiment 2

[0078] The bypass throttling element of the air conditioning system is an electronic expansion valve with a maximum opening of 480P, and when the bypass throttling element is opened, the widening range of the bypass throttling element is positively correlated with the outdoor ambient temperature.

[0079] Such as image 3 and Figure 4 As shown, the temperature detection device of the air conditioning system detects the temperature Tf of the electronic components, and transmits the detection signal to the controller, and the controller compares the temperature Tf with the first set temperature Ts1 and the second set temperature Ts2.

[0080] When Tf>Ts1, the controller controls the outdoor throttling element to close and judges the current opening degree of the bypass throttling element. If the opening degree of the bypass throttling element is smaller than the maximum value at this time, the controller controls the opening degree of the bypass throttling element to increase,...

Abstract

The invention discloses an air conditioner system and a control method thereof. The air conditioner system comprises an outdoor unit and at least one indoor unit. Each indoor unit comprises an indoor heat exchanger and an indoor throttling element. The outdoor unit comprises a compressor, a reversing assembly, an outdoor heat exchanger and a heat dissipation element. The reversing assembly comprises a first valve port, a second valve port, a third valve port and a fourth valve port. The heat dissipation element comprises a refrigerant heat dissipation part through which a refrigerant flows, and an air heat dissipation part making contact with outside air. The refrigerant heat dissipation part is in series connection with a bypass throttling element. The bypass throttling element and the refrigerant heat dissipation part which are in series connection are connected with an outdoor throttling element in parallel. Both the bypass throttling element and the outdoor throttling element have an opening-closing function. According to the air conditioner system, the problem that due to the adoption of air convection heat dissipation, the heat dissipation effect of an electronic element is poor is solved, and the problem of loss of part of an refrigerant in a refrigerant flow path of the air conditioner system due to the adoption of a bypass refrigerant mode for heat dissipation of the electronic element is avoided to a certain extent.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to an air-conditioning system and a control method for the air-conditioning system. Background technique [0002] During the operation of the air conditioning system, the electronic components on the outdoor unit will generate heat. The method for dissipating heat from electronic components in the related art generally utilizes air convection to dissipate heat, or bypasses part of the refrigerant of the air-conditioning system to the electronic components to achieve the purpose of heat dissipation. [0003] However, when the temperature of the electronic components is high, the air convection heat dissipation effect is not good. In order to ensure the normal operation of the air conditioner, the operating frequency of the compressor is usually limited to reduce the heat generation of the electronic components, which directly affects the capacity output of the compres...
