ABSTRACT:
A Freon type refrigerant, which is vented from a heat exchange system, such as an air-conditioner, is transferred directly from the exhaust valve of the heat exchange system through a tube to a collecting cylinder or tank. The outer metal side walls of the collecting tank are wrapped with a chemically activatable cold wrap. The cold wrap may, for example, contain therein a rupturable pouch having a chemical blend of ammonium nitrate and urea to isolate same from water within the cold wrap. Upon rupturing of the pouch, the chemical blend is dissolved in the water and an endothermic reaction is initiated. As a result, the heat within the tank is absorbed therefrom by the cold wrap causing the temperature and pressure inside of the tank to drop. This permits substantially all of the refrigerant in the heat exchange system to be transferred into the chilled tank in a condensed or liquid state. Alternately, a series of coils in contact with a chemically activatable cold wrap can be used to also assist the refrigerant to flow from a heat exchange system into a collecting tank in a condensed or liquid form.
