The following specification particularly describes the invention and the manner in which it is to be performed
BACKGROUND
Field of the Invention
[001] Embodiments of the present disclosure generally relate to a system and method for recycling waste water of a split air conditioner and particularly to a system and method for utilizing the waste water of the split air conditioner to cool down an outdoor unit.
Description of Related Art
[002] Increasing heat exposure levels are one of the most certain effects of climate change and there is a strong evidence of negative health impacts of environmental heat. Heat exposure is particularly problematic in tropical and subtropical climates, although there is a significant heatwave-related mortality risk in warmer temperate climates as well. The heat exposure is particularly problematic in large cities due to which it is referred to as an urban heat island effect. In addition, areas with already hot climates are the areas with high urbanization rates and population growth. This puts escalating numbers of people at risk.
[003] Air conditioning (AC) is promoted as an effective solution to reduce heat stress and protect from the heat exposure by providing indoor thermal comfort to avoid heat-related health problems. But during summer, a heat rejection capacity of an outdoor unit comes down due to a low-temperature difference between condenser coils and an ambiance. Typically, during the peak summer, outdoor temperatures during daytime go as high as 50o C. During the daytime, the condenser heat rejection capacity is affected by the outdoor air temperature. A fan is arranged normally at the outdoor unit to blow the surrounding air and make a convective heat current.
[004] There is thus a need for a system and method for managing cooling the outdoor unit of a split air conditioner in a more efficient manner to increase the cooling capacity as well as supplement heat removal at the outdoor unit.

[0026] Further, the outdoor unit 104 may comprise condenser coils 110, a drain pipe 112, a plurality of drippers 114a-114n, and so forth. The condenser coils 110 may be installed at a lower end of the outdoor unit 104. The condenser coils 110 may be configured to condense the refrigerant, resulting in a release of the heat that was absorbed from the premise. A fan (not shown) may be installed near the condenser coils 110, according to an embodiment of the present disclosure. The fan may be installed on a top of the outdoor unit 104, according to another embodiment of the present disclosure. The fan may be configured to blow air over the condenser coils 110, so that the refrigerant inside loses the heat. According to embodiments of the present disclosure, the condenser coils 110 may be many in number, such that many of the condenser coils 110 increase an amount of time the refrigerant is in a path of blowing air, giving it plenty of time to release the heat that was carried out of the premise.
[0027] The drain pipe 112 may be connected to the evaporator drain tray 108, according to embodiments of the present disclosure. The drain pipe 112 may be made up of a plastic material, according to an embodiment of the present disclosure. The drain pipe 112 may have a diameter in a range of 10 to 15 Millimeters (mm), according to an embodiment of the present disclosure.

[0029] At step 202, the spilt air conditioner may be configured by pressing a switch (not shown). The switch may generate an activation signal that may configure the indoor unit 102 and the outdoor unit 104.
[0030] At step 204, the split air conditioner may start sucking warm breeze in the premise, as a result of which the warm air may get condensed resulting in a formulation of the dew on the evaporator coils 106 due to cold refrigerant.
[0031] At step 206, the split air conditioner may collect the condensed dew in the evaporator drain tray 108 installed beneath the evaporator coils 106.
[0032] At step 208, the split air conditioner may channelize the condensed dew to the drippers 114 through the drain pipe 112 in the outdoor unit 104.
[0033] At step 210, the split air conditioner may release the collected dew over the condenser coils 110 through the drippers 114 resulting in better cooling during the summers.
