摘要

The line assembly has a filling unit, a flushing unit, an emptying unit of a brine circuit, a flow line connection (3) and return line connection (4) for environmental heat source, and a flow line connection (5) and a return line connection (6) for heat pump evaporator. The housing halves (1) made of expanded polypropylene (EPP), are insulated through the seal (16), such that both the flow and return line connections, are connected with the housing halves through the seal to create a gas-tight volume.
