ABSTRACT:
A heat transfer system combining a solar collector and a vapor jet compressor pump. The solar collector provides two streams of heated vapor, one at a relatively high temperature and one at a relatively low temperature. The high temperature vapor provides the motive vapor for the vapor jet compressor pump. The vapor jet compressor pump entrains the lower temperature vapor and acts as a heat pump effectively pumping its temperature to a higher temperature useful for space heating. The solar energy supply may be supplemented by an auxiliary convention energy source and the vapor jet compressor pump may be supplemented by a self-energized circulation pump.
