Description

Technical Field

[0001] This utility model relates to the field of fault monitoring and early warning technology, specifically to an online monitoring and early warning device for air conditioning unit faults. Background Technology

[0002] An air conditioning unit consists of an outdoor unit and an indoor unit. The outdoor unit typically contains a compressor, an outdoor heat exchanger, and an outdoor fan, while the indoor unit typically contains an indoor heat exchanger and an indoor fan. Among the malfunctions that occur in existing air conditioning units, major malfunctions such as compressor damage and burnt-out electrical control components are largely caused by minor faults in electrical components that were not promptly eliminated, resulting in the electrical components operating under fault conditions for an extended period of time.

[0003] A search revealed that patent application CN111006355B discloses an air conditioning unit and its operating status monitoring method and device. This includes real-time monitoring of the air conditioning unit's operating parameters, determining its health level based on these parameters, and providing fault warning evaluation based on the assessment results. By determining the air conditioning unit's health level based on operating parameters, users can monitor its operating status in real time. Furthermore, the fault warning evaluation allows users to promptly identify potential faults and take appropriate preventative measures, thereby ensuring the air conditioning unit remains in a healthy state over the long term.

[0004] However, since it can only monitor the operating parameters of the indoor unit, it cannot monitor the temperature, pressure, flow rate, and current of the air conditioning unit. The monitoring effect is poor, the functionality is low, and the practicality is low. At the same time, since the monitoring device is installed on the outer wall of the indoor unit, it is easy to affect its aesthetics and the performance is poor.

[0005] Therefore, we propose an online monitoring and early warning device for air conditioning unit faults. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an online monitoring and early warning device for air conditioning unit faults, which solves the problems of poor monitoring effect and low aesthetics of existing devices.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: an online monitoring and early warning device for air conditioning unit faults, comprising an indoor unit body and an outdoor unit body, wherein the front and sides of the indoor unit body are equipped with fan windows positioned opposite each other;

[0008] The indoor unit and outdoor unit are equipped with temperature sensors, pressure sensors, flow sensors, and current transformers that are positioned opposite each other and have compatible specifications. The indoor unit is equipped with a processor connected to each component. The front of the indoor unit is equipped with a display screen connected to the processor. The display screen displays five sets of fault codes represented by different numbers. The front of the indoor unit is equipped with three sets of alarm lights that are positioned opposite each other and connected to the display screen. The front of the indoor unit is equipped with a speaker connected to the alarm lights.

[0009] The front side of the indoor unit body has a groove of a matching size. An electric telescopic rod of a matching size is fixedly installed in the groove. A control processing board of a matching size is fixedly installed at the front end of the electric telescopic rod. The top surface of the control processing board is connected to the display screen. Sliding grooves are provided on the left and right sides of the groove. Sliding blocks of a matching size are fixedly installed on the left and right sides of the control processing board.

[0010] Preferably, the front side of the indoor unit is equipped with control buttons, which facilitates the control of each component.

[0011] Preferably, the front side of the indoor unit body is fitted with an access door opposite to the processor position by screws, which facilitates the maintenance of the processor.

[0012] Preferably, the front side of the inspection door is provided with evenly distributed heat dissipation holes A, which can improve the heat dissipation effect of the processor.

[0013] Preferably, the control processing board has evenly distributed heat dissipation holes B on its front side, which facilitates heat dissipation for the electronic components inside the control processing board.

[0014] Preferably, a heat-conducting layer is fitted on the rear side of the access door, which facilitates the conduction of heat dissipated by the processor to the access door, thereby improving heat dissipation efficiency.

[0015] 1. This air conditioning unit fault online monitoring and early warning device, through the setting of fault codes, alarm lights and speakers, temperature sensors, pressure sensors, flow sensors, and current transformers can monitor the temperature, pressure, cooling water flow, voltage and current and operating status of the air conditioning unit. When a fault occurs in any of them, the corresponding fault code will light up to indicate the fault. The degree of fault is divided into minor and serious and is warned by alarm lights and speakers. The monitoring effect is good.

[0016] 2. Simultaneously, through the setting of electric telescopic rod and sliding groove, when it is not necessary to observe fault codes, the electric telescopic rod drives the control processing board and display screen to retract into the groove. The sliding groove and slider can ensure the stability of the control processing board, thereby hiding it and improving the aesthetics of the indoor unit. Attached Figure Description
