DESC:FIELD
The present disclosure relates to the field of mechanical engineering. More specifically, the present disclosure relates to a system for cleaning of an evaporator of an air conditioning system used in a vehicle.
BACKGROUND
An evaporator is an important component of an air conditioning system as it provides the cooling of air in a vehicle. A tropical climate is particularly detrimental as it causes corrosion of the evaporators. Generally, vehicles are exposed to dust containing sulphur and chlorine constituents which, when accumulated on an evaporator, causes corrosion. The evaporator coils are made of aluminium and are prone to corrosion resulting from the reaction of the aluminum with the sulphur and chlorine constituents present in the atmosphere. The problem of corrosion of the evaporator coils is further aggravated when the air conditioning system is run in prolonged ‘Fresh Air Circulation mode’. Furthermore, when dust is deposited on the evaporator, the air passing through the evaporator gets a bad odour, which is unhygienic and undesirable.
Hence, in order to address the above mentioned drawbacks, there is need of a system for cleaning of the evaporator that facilitates the removal of dust from the surface of the evaporator.
SUMMARY
A system for cleaning an evaporator of an air conditioning system is disclosed in the present disclosure. The system comprises a tank containing a cleaning fluid in fluid communication with a pump. The pump is adapted to pressurize the cleaning fluid and supply the pressurized cleaning fluid to at least one conduit disposed near an operative top of the evaporator. The system further comprises a plurality of spray nozzles configured on the conduit. The spray nozzles are adapted to convert said pressurized cleaning fluid to an atomized cleaning fluid, and the atomized cleaning fluid is sprayed on the evaporator to remove dust accumulated on the evaporator. The system also comprises a tray disposed below the evaporator to receive a mixture of the cleaning fluid and dust and drain that mixture therefrom.

DETAILED DESCRIPTION
The arrangement will now be described with reference to the accompanying drawing, which does not restrict the scope and ambit of the present disclosure. The description is provided purely by the way of illustration.
The embodiment herein and the various features and advantageous details thereof are explained with reference to the non-limiting embodiment in the following description. Descriptions of well-known components and processing techniques are omitted so as to not unnecessarily obscure the embodiment herein. The example used herein is intended merely to facilitate an understanding of ways in which the embodiment herein may be practiced and to further enable those of skill in the art to practice the embodiment herein. Accordingly, the example should not be construed as limiting the scope of the embodiments herein.
The description hereinafter, of the specific embodiment will so fully reveal the general nature of the embodiment herein that others can, by applying current knowledge, readily modify and/or adapt for various applications. The specific embodiment without departing from the generic concept, and, therefore, such adaptations and modifications should and are intended to be comprehended within the meaning and range of equivalents of the disclosed embodiment. It is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation. Therefore, while the embodiment herein has been described in terms of a preferred embodiment, those skilled in the art will recognize that the embodiment herein can be practiced with modification within the spirit and scope of the embodiment as described.
Figure 1 illustrates a perspective view of a system for maintenance of an evaporator (hereinafter referred to as system 100), in accordance with an embodiment of the present disclosure. As seen in Figure 1, the system 100 for cleaning the evaporator 104 comprises a tank (not shown in figure) adapted to contain a cleaning fluid. The tank is in fluid communication with a pump (not shown in the figure), wherein the pump is adapted to pressurize the cleaning fluid. The pump may be any suitable pump selected from the conventionally available pumps, as per the application requirements. The system 100 further comprises a conduit 106 disposed near an operative top of the evaporator 104 and in fluid communication with the pump. The conduit 106 is configured to receive a pressurized cleaning fluid from the pump. In the present embodiment, the cleaning fluid is distilled water having a pre-determined pH. However, the cleaning fluid is not limited to distilled water, and other fluids of a mixture of fluids are within the ambit of the present disclosure. The conduit 106 has a plurality of spray nozzles 108 configured thereon. The plurality of spray nozzles 108 is configured on the conduit 106 operatively orthogonal to the evaporator 104. The plurality of spray nozzles 108 is adapted to atomize the pressurized cleaning fluid, thereby converting the pressurized cleaning fluid to an atomized cleaning fluid. The atomized cleaning fluid is sprayed onto the evaporator 104 to remove the dust accumulated thereon. The system 100 further comprises a tray (not shown in the figure) disposed below the evaporator 104 configured to receive a mixture of cleaning fluid and dust that was accumulated on the evaporator 104. The mixture of dust and the cleaning fluid can be drained from the tray during the regular maintenance of the vehicle.
The cleaning of the evaporator is performed by the spraying operation, as described above. The spraying operation can be performed automatically, where the actuation of the spray nozzles 108 is controlled by timers and the spraying operation is performed at pre-determined regular time intervals. In another embodiment, the actuation of the spray nozzle may be performed manually by triggering the spraying operation. Depending upon the size of the evaporator 104, the amount of water that is sprayed varies. A large evaporator will have more water sprayed on it, than an evaporator of a smaller size.
Various corrosion forming agents contained in the dust, like chlorides, sulphur, and copper, are removed from the evaporator 104 due to the sprays of the cleaning fluid on the evaporator 104. These corrosion forming agents flow down the evaporator surface and are collected in the tray. The removal of the dust from the evaporator surface 104 also prevents the air from getting a bad odour, thereby providing clean and hygienic air.
