Abstract
A sub cooling condensate trap as an auxiliary unit for an air conditioning system, comprising a container having a heat exchange coil disposed therein and through which hot liquid refrigerant is passed, and water inlet and outlets in the container through which condensate water from the air conditioner condenser is passed countercurrently to the refrigerant, thereby sub cooling the refrigerant and increasing the power usage efficiency of the air conditioning system.
Claims5
Apparatus for countercurrent sub cooling warm refrigerant from a condenser in an air conditioning system with cold condensate water from an evaporator disposed within an enclosure in said air conditioning system, comprising:
- a. an elongated container disposed outside the evaporator enclosure and having sidewalls, a bottom wall and a removable lid, said lid is provided with means for easy removal including being fabricated from a pliably material;
- b. water inlet and outlet means including first conduit means for connecting said water inlet means to a cold water outlet of a drip pan under the evaporator, and second conduit means connecting said water outlet means to a drain;
- and
- c. an elongated helical heat exchange coil disposed in said container and including third conduit means for connecting an upper end of said coil to a warm refrigerant outlet of the condenser, and fourth conduit means for connecting a lower end of said coil to a control device on an evaporator side of the air conditioning system, whereby warm refrigerant is cooled by cold condensate water in countercurrent flow of refrigerant and water through the apparatus.
