<p>The pump has a container (1) with a compressor (8), a condenser (10) forming a heat exchanger for a heating circuit, and an expansion valve (21). An evaporator forms an earth collector, where feed- and discharge lines (5, 6) of the earth collector are guided through the container and are connected to a cooling medium circuit within the container. Plug-in couplings with coupling parts are provided for detachably connecting the feed- and discharge lines to the cooling medium circuit. The coupling parts are self-lockable and are held opposite to each other in coupling bodies.</p> |
