A fluid system for controlling fluid temperatures and transferring heat from a thermal energy source such as a solar collector to point-of-need heat exchangers, remote from the collector from which heat is discharged for use. The fluid system blanket pressure, i.e., the pressure at the high point of the system, is maintained at a level such that the fluid vaporizes in the desired temperature operating range of the collector. The vapor collects in an accumulator that is connected in parallel in the heat transfer system with the collector. The accumulator serves to supply a regulated flow of vapor for motivating a vapor jet compressor-pump. The pump functions for the dual purposes of circulating the heat transfer fluid and as a vapor compressor for space cooling or the pumping of heat from the outside environment into the system to supplement the heat supplied by the collector.
