EXTRA EXTRA2 - 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. Model DHW produced in the first 10 minutes in lt/10’ input 10 °C output 45 °C, storage at t2 and primary at T1 DHW produced in the first hour in lt/60’ input 10 °C output 45 °C, storage at t2 and primary at T1 T1/t2 200 300 500 800 1000 1500 2000 2500 3000 4000 5000 Model 55/50 140 133 215 206 418 400 689 668 816 794 1149 1119 1595 1556 1652 1600 2303 2240 2972 2886 3882 3772 65/60 184 174 284 268 555 524 910 871 1066 1025 1512 1456 2095 2023 2186 2091 3021 2904 3894 3735 5066 4863 T1/t2 70/60 194 180 298 279 585 546 954 905 1107 1057 1579 1509 2187 2096 2296 2176 3149 3003 4059 3858 5263 5008 80/60 213 194 328 301 648 593 1046 977 1195 1124 1723 1622 2382 2250 2527 2354 3420 3209 4403 4115 5674 5309 DHW produced in the first 10 minutes in lt/10’ input 10 °C output 45 °C, storage at t2 and primary at T1 55/50 253 223 389 345 781 697 1207 1105 1312 1203 1947 1801 2672 2485 2963 2714 3865 3561 5026 4610 6414 5886 65/60 364 312 560 483 1132 982 1741 1555 1859 1664 2795 2526 3831 3483 4285 3825 5511 4949 7141 6374 9040 8064 70/60 408 344 628 534 1275 1088 1950 1719 2058 1816 3118 2783 4273 3834 4809 4233 6124 5423 7930 6967 9987 8764 80/60 502 412 773 639 1577 1314 2395 2063 2480 2136 3810 3324 5209 4573 5921 5089 7426 6411 9583 8198 11959 10208 DHW produced in the first hour in lt/60’ input 10 °C output 45 °C, storage at t2 and primary at T1 T1/t2 T1/t2 55/50 200 300 500 800 1000 1500 2000 2500 3000 4000 5000 65/60 70/60 80/60 55/50 65/60 70/60 80/60 247 241 371 362 649 632 1039 1018 1347 1316 1855 1825 2546 2507 2927 2888 3748 3685 4842 4756 6362 6252 319 308 480 464 844 813 1347 1308 1759 1703 2394 2338 3285 3212 3761 3688 4827 4710 6232 6070 8166 7963 328 314 494 474 874 836 1391 1342 1826 1756 2462 2392 3377 3285 3852 3761 4955 4809 6396 6196 8363 8109 347 329 524 496 937 882 1483 1414 1970 1869 2605 2504 3571 3439 4046 3915 5226 5015 6740 6452 8775 8409 360 330 545 501 1011 927 1555 1453 2143 1998 2651 2506 3622 3435 4003 3815 5307 5004 6892 6477 8891 8363 498 446 755 678 1420 1270 2177 1990 3041 2773 3675 3407 5019 4670 5495 5146 7314 6752 9475 8699 12137 11161 542 478 823 729 1563 1378 2386 2154 3365 3029 4000 3664 5459 5021 5935 5497 7928 7226 10263 9301 13081 11860 635 547 968 834 1866 1602 2831 2498 4056 3569 4689 4204 6391 5761 6867 6236 9230 8215 11913 10533 15058 13303 29 Flow rate Exchanger pressure loss [m3/h] [mm.H2O] [mbar] 2 1 3 1,5 6 3 10 5 10 5 15 7,5 20 10 20 10 20 10 20 10 20 10 294,35 80,5 355,7 95,97 682 179 1311 341 1311 341 2181 560 2846 728 2314 592 2745 700 3701 939 4472 1132 28,9 7,9 34,9 9,4 66,9 17,6 128,6 33,4 128,6 33,4 213,9 54,9 279,1 71,4 226,9 58,1 269,2 68,6 362,9 92,1 438,6 111,0 Flow rate Exchanger pressure loss [m3/h] [mm.H2O] [mbar] 2 1 3 1,5 6 3 10 5 15 7,5 15 7,5 20 10 20 10 20 10 20 10 20 10 309 84,74 372 101,02 718 189,22 1380 358,5 2295 589,6 2295 589,6 2996 766,42 2436 624 2836 723 3896 989 4707 1192 30,3 8,3 36,5 9,9 70,4 18,6 135,3 35,2 225,1 57,8 225,1 57,8 293,8 75,2 238,9 61,2 278,1 70,9 382,1 97,0 461,6 116,9
