Abstract
An automatic cleaning system for an air conditioner heat exchanger comprises a shell, a draught fan and the heat exchanger. The draught fan and the heat exchanger are installed in the shell. The bottom of the shell is provided with a water discharge port. A pipe network is arranged beside the heat exchanger. The pipe network is provided with multiple nozzles. The pipe network is connected with a main pipe outside the shell. A booster pump and a pulse electromagnetic valve are arranged in the middle of the main pipe. The booster pump and the pulse electromagnetic valve are electrically connected with a control module. A first wind pressure sensor and a second wind pressure sensor are installed at an air outlet and an air inlet of the heat exchanger respectively. The two wind pressure sensors are electrically connected with the control module respectively. According to the automatic cleaning system for the air conditioner heat exchanger, the booster pump and the pulse electromagnetic valve are used for providing high-pressure pulse cleaning liquid, heat transfer fins are cleaned in a spraying mode through the nozzles, and therefore the effect is quite good; moreover, the automatic cleaning system can conduct monitoring and cleaning automatically.

The Chinese invention patent application that and for example patent No. is 200910140261.2, this Patent Application Publication a kind of air conditioner, it comprises heat exchanger and injection unit.This air conditioner adopts the mode of jet cleaning liquid to clean air conditioner heat exchanger, and multiple spray regime is disclosed, these spray regimes are all that cleaning fluid is sprayed downwards from the top of heat exchanger, flow freely to clean air conditioner heat exchanger by cleaning fluid, cleaning performance has much room for improvement.
Summary of the invention
In order to solve in prior art, air conditioner heat exchanger cleaning device complex structure operation inconvenience and the poor problem of cleaning performance, the invention provides another heat exchanger of air condition automatic cleaning system, high-voltage pulse jet cleaning mode is not only provided, but also can automatically monitor automatic cleaning.
The technical scheme that technical solution problem of the present invention adopts is: a kind of heat exchanger of air condition automatic cleaning system, it comprises housing, blower fan and heat exchanger, described blower fan and heat exchanger are arranged in described housing, described heat exchanger comprises refrigerant tube and thermofin, be provided with discharge outlet at described housing bottom, clean the waste water of heat exchanger and discharge thus.It is characterized in that at the other pipe network that is provided with of described heat exchanger, on described pipe network, a side of phase heat exchanger is provided with multiple nozzles, described pipe network is connected with the supervisor outside housing, described supervisor's the other end is filter washing water inlet, described supervisor's centre is provided with booster pump and impulse electromagnetic valve, and described booster pump and described impulse electromagnetic valve are electrically connected with control module.The first wind pressure sensor and the second wind pressure sensor are installed respectively by wind outlet and inlet air place at described heat exchanger, and described the first wind pressure sensor and described the second wind pressure sensor are electrically connected with control module respectively.In the time that on the thermofin of heat exchanger, dust is too much, the wind pressure value that described the first wind pressure sensor and described the second wind pressure sensor record differs larger, in the time that the leeway of two wind pressure sensors reaches setting value, control module starts booster pump and impulse electromagnetic valve work, booster pump extracts cleaning fluid from filter washing water inlet, to supervisor's conveying high-pressure cleaning fluid, control module provides pulse signal to impulse electromagnetic valve, order about impulse electromagnetic valve with the continuous opening and closing of pulse signal, the cleaning fluid of high-voltage pulse is provided to pipe network, the cleaning fluid of high-voltage pulse sprays to thank on thermofin by nozzle it is cleaned.
The invention has the beneficial effects as follows: due to a kind of heat exchanger of air condition automatic cleaning system of the present invention, adopt booster pump and impulse electromagnetic valve to provide high-voltage pulse cleaning fluid, by nozzle, thermofin is carried out to jet cleaning, effect is good especially, and by the first wind pressure sensor, the second wind pressure sensor and control module automatically monitor and automatically control clean very easy.
