Prefilter System for Heat Transfer Unit and Method
First Claim
1. A method of transferring heat comprising:
- providing heat exchanger unit that is at least partially air cooled, the heat exchanger unit having an evaporator, condenser, compressor and a fan for forcing air over an exteriorly located heat exchange surface of the condenser;
positioning a fiberglass filter element adjacent to the heat exchange surface of the condenser for capturing at least one of grease, debris and other contaminants that are not entrained within any liquid cooling fluid that would otherwise contact the heat exchange surface; and
allowing the filter element to capture the at least one of grease, debris and other contaminants prior to contact with the heat exchange surface of the condenser.

Abstract
A method of transferring heat is accomplished by providing a heat exchanger unit that is at least partially air cooled. The heat exchanger unit has an evaporator, condenser, compressor and a fan for forcing air over an exteriorly located heat exchange surface of the condenser. A fiberglass filter element is positioned adjacent to the heat exchange surface of the condenser for capturing at least one of grease, debris and other contaminants that are not entrained within any liquid cooling fluid that would otherwise contact the heat exchange surface. The filter element is allowed to capture the at least one of grease, debris and other contaminants prior to contact with the heat exchange surface of the condenser.

providing heat exchanger unit that is at least partially air cooled, the heat exchanger unit having an evaporator, condenser, compressor and a fan for forcing air over a heat exchange surface of the condenser; positioning a filter element adjacent to the heat exchange surface of the condenser for capturing at least one of grease, debris and other contaminants that are not entrained within any liquid cooling fluid that would otherwise contact the heat exchange surface; allowing the filter element to capture the at least one of grease, debris and other contaminants prior to contact with the heat exchange surface of the condenser. providing a mist generator having at least one nozzle for directing a stream of fine mist or atomized liquid coolant into the air between the filter element and the heat exchange surface of the condenser, the mist generator being coupled to a supply of liquid coolant; and controlling the degree of mist or atomized coolant generated by the mist generator with a controller. - View Dependent Claims (18)
