Cold or heat producing circuit

摘要

The heat or cold supply circuit has a compressor, an evaporator, a condenser and a throttle element (16), formed as a separate component fitted directly between 2 elements of the supply circuit, e.g. a connection pipe (10) and a connection fitting (11) and provided with a throttle disc having a central flow opening (22). The throttle element may act simultaneously as a seal between the circuit elements between which it is inserted, e.g. via an integrated O-ring seal (24).
