Abstract:
1. A heating and air-conditioning installation with a heat-transfer fluid and including a heat-transfer fluid distributor unit, the unit comprising: first and second inlet/outlets for the heat-transfer fluid; at least one third inlet/outlet for the heat-transfer fluid and suitable for being connected to a corresponding circuit for collecting heat; at least one fourth inlet/outlet for the heat-transfer fluid, suitable for being connected to a corresponding circuit for delivering heat; distributor means suitable for selectively interconnecting in various different predetermined fluid distribution combinational schemes: the first inlet/outlet to at least one of the third and fourth inlet/outlets, and the second inlet/outlet to at least one of the third and fourth inlet/outlets, the distributor means comprising a network of interconnection pipes connected to one another and connected to the inlet/outlets and each provided with an individually controllable stop valve; and control means for collectively controlling the various stop valves of the unit so as to select any one of said combinational schemes in modifiable manner; the installation includes a water/water type heat pump with a hot-side heat exchanger and a cold-side heat exchanger said heat-transfer fluid flows, said heat-transfer fluid being common to the hot-side heat exchanger of the heat pump, to the cold-side heat exchanger of the heat pump, to the heat collector circuit, and to the heat delivery circuit; and the distributor unit is connected to the hot-side heat exchanger via the first heat-transfer fluid inlet/outlet, and to the cold-side heat exchanger via the second heat-transfer fluid inlet/outlet.
