HEATING/AIR-CONDITIONING PLANT WITH HEAT PUMP, COMPRISING A HEAT TRANSFER FLUID SPLITTER BOX WITH COUPLING TO A PLURALITY OF HEAT COLLECTING AND DISTRIBUTING CIRCUITS

摘要

The splitter box (10) is coupled to a heat pump (12) and to various heat collecting (24, 28, 30) and heat delivery (38, 40, 52, 56) circuits that it selectively interconnects according to various predetermined fluid-distribution combinational diagrams by automatic control of an inbuilt network of stop valves (200). These diagrams define modes of operation such as natural cooling or frost protection, hot water production and/or air-conditioning from a single plant, by optimizing the transfers of heat between circuits such that the heat pump always operates in its optimum thermodynamic zone.
