Heating and air-conditioning installation with a heat pump, the installation including at least one heat transfer fluid distributor unit with coupling to a plurality of heat collection and delivery circuits
The distributor unit (10) is coupled to a heat pump (12) and to various circuits for collecting (24, 28, 30) and for delivering (38, 40, 52, 56) heat, with the unit serving to provide selective interconnection therebetween in application of various predetermined combinational schemes for fluid distribution by automatically controlling an integrated network of stop valves (200). The schemes define modes of operation such as natural cooling or freeze-proofing, producing hot water and/or air conditioning from a single installation by optimizing transfers of heat between the circuits so that the heat pump is always operating in its thermodynamically optimum zone.
