EXTRA EXTRA1 - HEAT EXCHANGERS TECHNICAL DATA Data have been calculated on following basis: 1) Primary circuit at T1 and proper energy source; 2) Production of DHW in continue way from 10 °C at t2; 3) DHW that can be taken in the first 10’ and in the first hour from storage at 60°C, input 10°C and output 45°C; 4) Sanitary water according to UNI CTI 8065. DHW produced in the first 10 minutes in lt/10’ input 10 °C output 45 °C, storage at t2 and primary at T1 Model DHW produced in the first hour in lt/60’ input 10 °C output 45 °C, storage at t2 and primary at T1 T1/t2 55/50 247 241 371 362 616 604 998 980 1273 1252 1855 1825 2546 2507 2988 2936 3748 3685 4842 4756 6362 6252 200 300 500 800 1000 1500 2000 2500 3000 4000 5000 65/60 319 308 480 464 791 770 1280 1249 1640 1601 2394 2338 3285 3212 3856 3760 4827 4710 6232 6070 8166 7963 Flow rate T1/t2 70/60 328 314 494 474 810 784 1310 1271 1683 1635 2462 2392 3377 3285 3965 3845 4955 4809 6396 6196 8363 8109 80/60 347 329 524 496 851 814 1373 1318 1776 1707 2605 2504 3571 3439 4196 4023 5226 5015 6740 6452 8775 8409 55/50 360 330 545 501 849 792 1359 1275 1788 1687 2651 2506 3622 3435 4296 4047 5307 5004 6892 6477 8891 8363 65/60 498 446 755 678 1162 1061 1855 1705 2469 2283 3675 3407 5019 4670 5951 5491 7314 6752 9475 8699 12137 11161 70/60 542 478 823 729 1254 1129 1998 1812 2678 2446 4000 3664 5459 5021 6475 5899 7928 7226 10263 9301 13081 11860 Chart for surfaces of: 4 m2 / 5 m2 / 6 m2 Exchanger pressure loss [m3/h] [mm.H2O] [mbar] 2 1 3 1,5 4 2 6 3 10 5 15 7,5 20 10 20 10 20 10 20 10 20 10 80/60 635 547 968 834 1450 1273 2301 2037 3123 2790 4689 4204 6391 5761 7586 6755 9230 8215 11913 10533 15058 13303 309 84,74 372 101,02 419 113,381 718 189,22 1380 358,5 2295 589,6 2996 766,42 2436 624 2836 723 3896 989 4707 1192 30,3 8,3 36,5 9,9 41,1 11,1 70,4 18,6 135,3 35,2 225,1 57,8 293,8 75,2 238,9 61,2 278,1 70,9 382,1 97,0 461,6 116,9 Chart for surfaces of: 8 m2 / 10 m2 Flow Rate [lt/min] Flow Rate [lt/min] 0 50 100 150 200 250 0 300 350 50 100 150 200 250 300 350 5000 400 400 10 m2 5000 450 4500 450 4000 400 3500 350 3000 300 2500 250 2000 200 1500 150 1000 100 50 500 50 300 6 m2 250 2500 5 m2 2000 200 1500 150 1000 500 0 0 0 0 5 10 15 20 [mm H 2O] 350 100 4 m2 3000 3500 [mbar] [mm H 2O] 4000 400 8m 2 0 0 25 5 3 15 3 Flow Rate [m /h] Model 10 Flow Rate [m /h] Storage volume: Standard heat exchanger Storage volume: Heat exchanger for 100% heated volume Advantage in storaged volume Advantage in percentage [liters] [liters] [liters] [%] 1500 1224 1440 216 2000 1684 1980 297 15% 15% 18% 17% 17% 17% 2500 1905 2314 409 3000 2438 2921 483 4000 3113 3765 652 5000 4116 4985 869 19 20 25 [mbar] 4500
