  • Refrigeration system for an environmental test chamber
    Patent number: 6536518
    Abstract: An environmental test chamber provides a fast cool down to a temperature of about −125° F. and a fast heat up of an element under test. The environmental test chamber fast cool down and heat up system comprises: an environmental test chamber having a fast cool down evaporator and fast heat up condenser coil, wherein the coil is selectively coupled either to receive a hot refrigerant gas flow or to receive a sub-cooled refrigerant flow; a cascade condenser coupled to the environmental test chamber; a primary stage sub-system coupled to the cascade condenser; a secondary stage sub-system coupled to the cascade condenser; and a thermal storage unit coupled to the primary stage sub-system and to the secondary stage sub-system. Wherein the environmental test chamber has an operational temperature down to about −125° F.
