TH3376A - Heat transfer circuit with dual source - Google Patents

Abstract

The refrigeration or air conditioning circuit has an injection machine through which the refrigerant is driven from the heated supply to Collect that has not been heated Refrigerant injection machine From a branch circuit with an expansion valve and a type heat exchanger Evaporator which provides cooling Application of the switching valve Of two storage sources when the cooling source is empty So that the operation of the circuit is not interrupted.

Claims (1)

1. The heat transfer circuit with the main flow circuit, which has an injection path, which supplies the working fluid as a vapor that is obtained. Heat in the first way source of storage To achieve Low pressure at the suction side inlet of the sprayer path, the path for Cooling and collecting the working fluid after it has been Through the injector path, and the branch circuit which connects the ends One with the suction side inlet And there is a heat exchanger Evaporators and expansion valves are located to expand the working fluid at It is liquid from an A-Diabatic main circuit into the exchanger.
