Abstract

A circuit for the generation of cold or heat comprising a compressor, an evaporator, a condenser and a restriction member made as a separate component and having a fixed throughflow cross-section, with the restriction member being inserted directly between two elements of the circuit such as a connection tube and a connection stub to reduce the manufacturing costs and the required construction space.
