[0038] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0039] The inventors have found that the refrigerant used in HVAC equipment leaks into the electric control box, which has electronic devices and generates heat, and there is a risk of detonating the refrigerant. If the electric control box is sealed to prevent the refrigerant from entering the electric control box, there will be no wind field inside the electric control box, and the heat dissipation effect will be poor, affecting the stability of the operation of the electric control box. Based on this, the embodiments of the present application provide an electric control system and HVAC equipment.

[0040] like Figure 1 , which is an architecture diagram of an electric control system 10 according to an embodiment of the present application, the electric control system 10 includes an electric control box 100 , an abnormality monitoring module 200 and a wind control module 300 .

[0041] like Figure 2As shown, the electric control box 100 is used to be installed in the internal space of the shell 22 of the HVAC equipment 20. For example, the internal space of the shell 22 of the HVAC equipment 20 includes a wind cavity for accommodating the fan 21, and the electric control box 100 is accommodated in the wind cavity. Of course, the internal space of the shell 22 of the HVAC equipment 20 also includes other areas for accommodating other functional components 23, and the various areas are interconnected or spaced apart. The embodiment of the present application does not limit the connectivity of the various areas of the internal space of the shell 22 of the HVAC equipment 20, and does not limit the installation position of the various functional components 23 installed in the internal space of the shell 22 of the HVAC equipment 20. The specific selection can be made according to actual needs.

[0042] like Figures 3 to 5 As shown, the electric control box 100 includes a housing 110, which is mounted on a support member of the HVAC equipment 20, for example, the support member includes a housing 22 of the HVAC equipment 20, a plate or a frame arranged in the inner space of the housing 22, etc. The housing 110 has a guide air duct 111 for gas circulation, and the gas flowing in the guide air duct 111 can prevent the accumulation of combustible substances in the electric control box 100, so as to disperse the combustible substances in time and reduce safety hazards.

[0043] The housing 110 of the electric control box 100 has a receiving cavity, wherein a part of the receiving cavity forms a guide air duct 111, and the remaining area forms an installation area. The electric control box 100 also includes a plurality of electric control components 130, and the plurality of electric control components 130 may be arranged in the installation area; or, a part of the electric control components 130 may be arranged in the installation area, and another part of the electric control components 130 may be arranged in the guide air duct 111. When the electric control components 130 are arranged in the guide air duct 111, the gas flowing through the guide air duct 111 can take away the heat of the electric control components 130 arranged in the guide air duct 111, reduce the temperature of the electric control box 100, and enable the electric control components 130 of the electric control box 100 to operate stably, while reducing the risk of combustion and explosion of combustible materials in the electric control box 100.

[0044] The guide air duct 111 can be connected to the installation area. When the gas flows through the guide air duct 111, it can also drive the gas flow in the installation area, so that the area where the gas flows in the accommodating cavity is larger, which is convenient for more efficient heat dissipation and more efficient dissipation of combustible materials.

[0045] The abnormal monitoring module 200 is used to sense the state of the electric control box 100 and generate state parameters, and the state parameters include at least one of temperature parameters, refrigerant leakage parameters, and equipment operation parameters. Specifically, the state of the electric control box 100 sensed by the abnormal monitoring module 200 includes the temperature state of the electric control box 100, the refrigerant state of the electric control box 100, and the operation state of the HVAC equipment 20 at the electric control box 100. Correspondingly, the abnormal monitoring module 200 generates temperature parameters according to the temperature state of the electric control box 100, generates refrigerant leakage parameters according to the refrigerant state of the electric control box 100, and generates equipment operation parameters according to the operation state of the HVAC equipment 20.

[0046] The wind control module 300 is disposed at the guide air duct 111, and the wind control module 300 has an open state that allows airflow to pass through the guide air duct 111, and a closed state that blocks airflow from passing through the guide air duct 111. Figure 3 As shown, it is a schematic diagram of the structure of the wind control module 300 in the open state. Figure 4 , which is a schematic diagram of the structure of the wind control module 300 in the closed state. The wind control module 300 switches to the open state or the closed state according to the comparison result of the state parameter and the preset parameter threshold. The preset parameter threshold includes a preset temperature threshold corresponding to the temperature parameter, a preset refrigerant threshold corresponding to the refrigerant leakage parameter, and a preset control threshold corresponding to the equipment operation parameter.

[0047] Among them, the situations of switching the risk control module 300 to the on state or the off state according to the comparison result of a single state parameter and the corresponding preset parameter threshold include the following three situations:

[0048] Case 1: When the temperature parameter is greater than or equal to the preset temperature threshold, the wind control module 300 is in the on state; when the temperature parameter is less than the preset temperature threshold, the wind control module 300 can be in the on state or the off state.

[0049] Case 2: When the refrigerant leakage parameter is greater than or equal to the preset refrigerant threshold, the wind control module 300 is in the closed state; when the refrigerant leakage parameter is less than the preset refrigerant threshold, the wind control module 300 can be in the open state or the closed state.

[0050] Case 3: When the equipment operating parameter is greater than or equal to the preset control threshold, the wind control module 300 is in the closed state; when the equipment operating parameter is less than the preset control threshold, the wind control module 300 can be in the open state or the closed state.

[0051] In the above-mentioned situations 1 to 3, when any one of the three parameters, temperature parameter, refrigerant leakage parameter, and equipment operation parameter, reaches a value that requires switching the wind control module 300 to the closed state, the wind control module 300 is directly switched to the closed state, so that the accommodating chamber of the electric control box 100 is in a closed state, protecting the electric control device 130 in the electric control box 100, and preventing the leaked refrigerant from entering the accommodating chamber and causing combustion and explosion. When none of the three parameters, temperature parameter, refrigerant leakage parameter, and equipment operation parameter, reaches a value that requires switching the wind control module 300 to the closed state, the wind control module 300 can be set to the closed state or the open state according to the needs. For example, the wind control module 300 can be directly set to the open state to dissipate heat, which helps to improve the stability of the operation of the electric control device 130 in the electric control box 100.

[0052] The electric control system 10 of the embodiment of the present application comprehensively considers the states of the electric control box 100 and the HVAC equipment 20, and uses the state parameters of the electric control box 100 and the HVAC equipment 20 to control the wind control module 300 to a closed state or an open state, so as to improve the safety and stability of the use of the electric control box 100. Among them, the temperature state and the refrigerant quantity state at the electric control box 100 are taken into consideration, and the heat dissipation demand and the anti-explosion demand of the electric control box 100 can be taken into account, so as to timely adjust the wind control module 300 to an open state to dissipate heat from the electric control box 100, and to facilitate timely adjustment of the wind control module 300 to a closed state to make the inside of the electric control box 100 closed to prevent explosion.

The control module 400 is also connected to the wind control module 300 by signal, and controls the wind control module 300 to be in an on state or an off state according to the comparison result between the state parameter and the preset parameter threshold.
