Description

Condensing unit
Technical Field
The present application relates to a condensing unit suitable for use with an evaporator in an air conditioning system; and more particularly to an environmentally friendly condensing unit that reduces the temperature of waste heat released into the environment when used in conjunction with an evaporator in an air conditioning system.
Background
Air conditioning systems have been widely used to cool a given area to achieve a comfortable indoor temperature, particularly for those living in hot climates. It is noted that during operation of the condensing unit of the air conditioning system, a significant amount of waste heat is also rejected by the condensing unit of the air conditioning system to the outdoor environment while providing the desired cooling effect. The exhausted waste heat can increase the outdoor temperature and aggravate the severity of the urban heat island. It should be noted that higher or warmer outdoor temperatures eventually result in increased air conditioning requirements, creating a positive feedback loop.
Furthermore, the condensed water produced by the evaporator of the air conditioning system is generally discharged into the environment and not utilized. The disordered drainage of the condensed water not only influences the appearance of the building, but also wastes free water sources.
In view of these and other drawbacks, it is desirable to provide a condensing unit that is capable of reducing the temperature of waste heat discharged into the outdoor environment during operation thereof. Furthermore, it is another object of the present application to provide a condensing unit that utilizes condensed cold water as an additional cooling medium and water source during its operation.
In the detailed description, a condensing device according to a preferred embodiment of the present application and a combination of elements or components thereof will be described and/or exemplified.

The water pump is configured to deliver and supply water contained in the water reservoir to the housing through at least one conduit in fluid communication with at least one inlet of the housing. It should be noted that water entering the enclosure absorbs heat from the condensing means during operation of the condensing means. In the preferred embodiment, water entering the housing will exit the housing through at least one outlet of the housing. According to this preferred embodiment, the water leaving the housing is transported to the at least one evaporation pad through at least one first conduit in fluid communication with at least one outlet of the housing. It should be noted that the water is preferably delivered to the top of at least one evaporative pad such that the water flows down and wets the entire evaporative pad.
In another preferred embodiment of the present application, the condensing means is provided with a first water pump and a second water pump. The first water pump of the condensation device is configured to convey and supply water contained in the water reservoir to the enclosure through at least one conduit in fluid communication with at least one inlet of the enclosure. It should be noted that water entering the enclosure absorbs heat from the condensing means during operation of the condensing means. In the preferred embodiment, water entering the housing will exit the housing through at least one outlet of the housing. According to the preferred embodiment, water leaving the housing is transported back to the reservoir through at least one conduit in fluid communication with at least one outlet of the housing. According to this preferred embodiment, the second water pump of the condensation device is configured to continuously transport and supply the water contained in the water reservoir to the at least one evaporation pad through at least one first conduit operatively connected to the second water pump of the condensation device.

It should be noted that the centrifugal fan is configured to draw ambient air from the at least one porous side wall of the condensing means through the wet evaporative pad. It will be appreciated that as air flows over the wetted evaporative pad, the air being drawn in carries heat away from the wetted evaporative pad. According to each of the preferred embodiments of the present application, air flowing through the wet evaporative pad is exhausted through the outlet vents of the condensing unit and excess water from the wet evaporative pad is cascaded back into the water reservoir.
According to each of the preferred embodiments of the present application, the condensate formed on the evaporator coil of the evaporator is discharged through the condensate line into the reservoir of the condensing device.
