Abstract
An air conditioning or refrigeration system includes a secondary loop cooling system for use with a vapor compression system having a bypass line in order to bypass a reservoir in the secondary loop system. This bypass allows the air conditioning or refrigeration system to cool down more quickly. The secondary loop cooling system uses a non-flammable cooling fluid, which is particularly useful when the refrigerant used in the vapor compression system is flammable.
