Air conditioning system with pre-cooler

Abstract

The air conditioning system with pre-cooler includes a compressor; a condenser; an evaporator; a condensate reservoir to collect condensed water discharged from the evaporator; and a condensate pump associated with the condensate reservoir. In one embodiment, the system includes a single pre-cooler that uses condensate to precool air before it reaches the evaporator. In a second embodiment, the system includes a sub-cooler between the condenser and an expansion valve that uses the condensate to pre-cool the refrigerant before it reaches the evaporator. In a third embodiment, the system includes a first pre-cooler that uses condensate to precool air before it reaches the evaporator; a sub-cooler between the condenser and an expansion valve that uses the condensate to pre-cool the refrigerant before it reaches the evaporator; and a second pre-cooler that uses the condensate to pre-cool air before it reaches the condenser.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of U.S. Provisional Patent Application Ser. No. 62 / 012,955, filed Jun. 16, 2014.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to air conditioning systems, and particularly to an air conditioning system that recirculates the condensate to precool air or to sub-cool refrigerant.[0004]2. Description of the Related Art[0005]An air conditioner (often referred to as “AC”) is an appliance, system, or mechanism designed to extract heat from an area. The cooling is done using a simple refrigeration cycle. Its purpose, in a building or an automobile, is to provide comfort during hot weather. In the refrigeration cycle, a heat pump transfers heat from a lower-temperature heat source into a higher-temperature heat sink. Heat would naturally flow in the opposite direction. This is the most common type of air conditioning. This cycle takes advantage of the way phase chan...

AI Technical Summary

Benefits of technology

The air conditioning system described in this patent has several features including a compressor, condenser, evaporator, refrigerant conduits, and a condensate reservoir and pump. These features work together to improve the efficiency and effectiveness of the air conditioning system. The patent describes different embodiments of the system that have further improved features such as a single or double pre-cooler that uses condensate to cool the air before it reaches the evaporator, or a sub-cooler that uses the condensate to cool the refrigerant before it reaches the evaporator. These features help to make the air conditioning system more efficient and effective in cooling the air.

Problems solved by technology

Most high occupancy buildings, such as schools, airports, office buildings, hotels and shopping malls, have high interior relative humidity and large amounts of air conditioner condensate.
