EVALUATION OF A GROUND COUPLED AIR-TO-AIR (CRAWL SPACE) HEAT PUMP.

Author(s) : SMITH L. O., REID R. L.

Summary

A CONVENTIONAL PRODUCTION MODEL SPLIT-UNIT AIR-TO-AIR HEAT PUMP WAS INSTALLED IN AN UNCONVENTIONAL MANNER. THE OUTDOOR PACKAGE OF THE HEAT PUMP WAS INSTALLED ON THE WEST END OF THE BUILDING SO AS TO ALLOW THE HEAT PUMP TO DRAW AMBIENT AIR THROUGH THE CRAWL SPACE THAT ENTERED OPENINGS IN THE EAST END OF THE CRAWL SPACE. AFTER PASSING OVER THE OUTDOOR HEAT EXCHANGER, THE AIR WAS THEN EXHAUSTED BACK TO AMBIENT. A SECOND INSTALLATION WAS INVESTIGATED ANALYTICALLY FOR A SEALED CRAWL SPACE WHERE THE < OUTDOOR > PACKAGE WOULD BE PHYSICALLY INSTALLED IN THE CRAWL SPACE AND WOULD RECIRCULATE THE CRAWL SPACE AIR. THE SINGLE-PASS INSTALLATION WOULD GIVE A NET SAVING OF 22.5% ON A FIVE-MONTH HEATING BILL AND THE RECIRCULATING INSTALLATION SHOWED A PREDICTED 31.5% NET SAVING FOR A FIVE-MONTH HEATING BILL.
