Summary

SOME VITAL CONDITIONS REGARDING AIR/WATER HEAT PUMPS ARE ANALYZED BY USE OF COMPUTER SIMULATIONS OF A MIDDLE SIZED HEAT PUMP SYSTEM. HEAT PUMPS, AND SPECIALLY AIR SOURCE UNITS, SHOULD ALWAYS BE USED IN COMBINATION WITH CONVENTIONAL HEATING EQUIPMENT FOR PEAK LOAD SUPPLY (BIVALENT SYSTEMS). ANALYSIS OF THE EVAPORATOR SHOWS THAT IT SHOULD BE DESIGNED FOR 120 TO 130 W/M2 SPECIFIC LOAD AND 2-2.2 M/S INLET AIR VELOCITY, WHICH IS WELL BELOW COMMON PRACTICE IN DESIGNING STANDARD AIR COOLERS. THE CONDENSER LOGARITMIC MEAN TEMPERATURE DIFFERENCE SHOULD BE CHOSEN ABOUT 4 K (4 DEG C), WHILE THE CORRESPONDING IS CALCULATED TO ABOUT 8.5 K (8.5 DEG C).
