EXPERIENCE OF A SEA WATER BASED HEAT PUMP IN HARSTAD, NORWAY.

Author(s) : EGGEN G.

Summary

AN R22 HEAT PUMP PREHEATS DOMESTIC WATER AND ALSO SUPPLIES HOT WATER FOR ROOM HEATING. THE RETURN WATER PREHEATS VENTILATING AIR. WATER TO AIR HEAT EXCHANGERS WERE SIZED FOR A MAXIMUM WATER TEMPERATURE OF 318 K (45 DEG C) IN 261 K (-12 DEG C) AMBIENT. A COMPUTER SIMULATION WAS DEVISED AND AN OVERALL COP OF 3.2 WAS PREDICTED. THE INSTALLATION PERFORMED SATISFACTORILY AT SEA WATER TEMPERATURES OF 275 K (2 DEG C), AND THE AUSTENITIC STAINLESS STEEL HEAT EXCHANGERS SHOWED NO SIGNS OF CRACKING. EXTENSIVE MEASUREMENTS WHICH WERE MADE WHILST THE PLANT WAS NOT RUNNING AT FULL CAPACITY GAVE AN OVERALL COP OF 3.0. G.R.S.
