TH3376A - Heat transfer circuit with dual source - Google Patents

Abstract

A refrigeration or air conditioning circuit has an injector through which refrigerant is driven from a heated supply reservoir to an unheated storage reservoir. The injector draws refrigerant from a branch circuit containing an expansion valve and an evaporative heat exchanger which provides cooling. Switching valves are used to change the function of the two reservoirs when the refrigerant supply reservoir is idle, ensuring that the circuit's operation is not interrupted.
