Description

TECHNICAL FIELD

[0001] The application relates to the technical field of central air conditioner water leakage prevention detection, and in particular to a central air conditioner water leakage prevention optimized installation detection device. BACKGROUND

[0002] A central air conditioner is composed of an air handling device (such as a combined air conditioning unit, a fan coil), a heat and humidity handling device (i.e. a cold and heat source or an air conditioner host), a supply air and return air duct, and various terminal air outlet units (i.e. fan coil or indoor unit, etc.). Today, central air conditioners are widely used in commercial and industrial buildings and some large residential buildings. The water pan of the central air conditioner is usually located in the pipeline part connected between the indoor and outdoor units, mainly to receive the condensate water generated during the operation of the air conditioner. The condensate water is due to the condensation of water droplets on the surface of the evaporator when the air conditioner is in cooling or dehumidifying. These water droplets are collected by the water pan and discharged outside to prevent water accumulation and leakage. In a common installation environment, the water pan may be installed on the ceiling, wall or other appropriate position of the indoor unit, or on the side of the duct of the outdoor unit. In large buildings such as shopping malls or office buildings, the water pans may be connected into a large water collection tank, and then the waste water is discharged through the drainage pipeline.

[0003] In the related art, the main reasons for water leakage of the water pan of the central air conditioner include factors such as blockage of the water pan drain, poor drainage of the pipeline, uneven installation of the indoor unit, and unreasonable design of the water pan. However, the water leakage prevention detection effect of the water pan is poor, and once the condensate water in the water pan leaks, it is difficult to discover and handle in the early stage of leakage, which may damage the central air conditioner and cause unstable operation of the central air conditioner.

[0004] Therefore, the application provides a central air conditioner water leakage prevention optimized installation detection device to solve the above problems. CONTENT OF THE INVENTION

[0035] In this embodiment, the suction pipe 8 is fixedly connected with the same filter cover 10 at one end of the air conditioner water pan 1 and one end of the condensate water discharge pipe 4 located in the air conditioner water pan 1. The filter cover 10 is in a spherical shape.

[0036] In this embodiment, the water outlet pipe 9 is fixedly installed with a one-way valve 12, and the one-way valve 12 is located between the water outlet pipe 9 and the detection box 2. The one-way valve 12 can avoid the backflow of the pumped condensate water to the air conditioner water pan 1 through the condensate water discharge pipe 4.

[0037] In this embodiment, the bottom inner wall of the detection box 2 is a inclined surface structure concave from the middle. Two filter screens 16 are fixedly installed on the bottom inner wall of the detection box 2, and the detection cylinder 5 is located between the two filter screens 16. The top of each of the two filter screens 16 is fixedly connected with the bottom of the air conditioner water pan 1. The filter screen 16 is used for filtering the condensate water entering the detection box 2, further ensuring the normal operation of the key components such as the detection cylinder 5, and preventing impurities from causing damage or inaccurate water leakage detection.

[0038] In this embodiment, a triangular flow guide seat 17 is fixedly installed on the bottom inner wall of the air conditioner water pan 1. The upper surface of the triangular flow guide seat 17 is an inclined surface structure. The triangular flow guide seat 17 is used for guiding the condensate water to flow to the vicinity of the condensate water discharge pipe 4 and the suction pipe 8, improving the efficiency of automatic discharge of the condensate water and extraction of the condensate water by the water pump 7, and making the drainage process more smooth.

[0039] Through the above structure, the working principle of the central air conditioner anti-leakage optimized installation and detection equipment provided by the present application is as follows:

[0040] When the central air conditioner is running, the condensate water flows into the air conditioner water pan 1. Under normal circumstances, the condensate water flows out through the condensate water discharge pipe 4 under the guidance of the triangular flow guide seat 17, realizing the preliminary drainage function.

[0041] When the condensate in the air conditioner water pan 1 leaks, the outflowing condensate flows into the detection box 2, and then flows into the detection cylinder 5 through the inclined surface of the inner wall at the bottom of the detection box 2. When the water immersion sensor 6 detects the presence of condensate in the detection cylinder 5, the water immersion sensor 6 transmits a detection signal to the controller 15. At this time, the controller 15 receives the signal, makes a judgment, and issues an instruction to control the operation of the water pump 7. When the water pump 7 operates, it will extract the condensate in the air conditioner water pan 1, so that the condensate in the air conditioner water pan 1 flows through the water suction pipe 8 and then is discharged through the water outlet pipe 9. The condensate discharged from the water outlet pipe 9 flows out through the condensate discharge pipe 4. At the same time, the controller 15 also controls the operation of the flow sensor 11 and the opening of the electromagnetic residual discharge valve 14. After the electromagnetic residual discharge valve 14 is opened, the condensate in the detection cylinder 5 is discharged through the residual discharge pipe 13. The flow sensor 11 detects the flow (i.e. the amount of water pumped) of the condensate in the water suction pipe 8. When the amount of water pumped monitored by the flow sensor 11 is less than the set value, it means that the condensate in the air conditioner water pan 1 will be pumped out soon. The signal monitored by the flow sensor 11 is transmitted to the controller 15. At this time, the controller 15 issues an instruction to control the water pump 7 to stop operating and closes the electromagnetic residual discharge valve 14, thereby accelerating the discharge of the condensate in the air conditioner water pan 1 and relieving the problem of poor drainage, effectively reducing the damage to the central air conditioner caused by the condensate leakage not being discovered in time.

[0042] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application. Any equivalent changes made according to the structure, shape, and principle of the present application should be covered by the protection scope of the present application.
