ADVANCED HEAT PUMP TECHNIQUES.

Author(s) : JACOBSEN C.

Summary

FOR WATER-WATER HEAT PUMPS, SEVERAL HEAT SOURCES CAN BE USED EVEN IF WATER IS CORROSIVE, WITH IMPURITIES, POLLUTED OR COLD. SHELL AND TUBE EXCHANGERS WERE USED AS EVAPORATORS, BUT PLATE-TYPE EXCHANGERS APPEARED EFFICIENT AND ECONOMIC. THE AUTHOR SHOWS THE BUILDING REQUIREMENTS OF SOME PLANT AND THE STALFAPLATE DIRECT EXPANSION PLATE-TYPE HEAT EXCHANGER. THIS IS BEING TESTED WITH HEAT SOURCES OF 100 TO 4 MW, OPERATING WITH SEA WATER. IT HAS A GOOD RESISTANCE TO CORROSION. THE USERS REQUIRE INCREASINGLY HIGH TEMPERATURES. 353 K (80 DEG C) IS THE STANDARD TEMPERATURE OF R12 PLANT. R114 MACHINES WORK AT ABOUT 373 K (100 DEG C).
