39 Relax: We will show you a short cut Step 1: Calculate the Total Equivalent Length (TEL) Step 2: Calculate the Available Static Pressure Step 3: Calculate the Friction Rate Step 4: Determine how much air each duct section is carrying Step 5: Size the ducts 40

40 Comparison of Equivalent Lengths (ELs) EL=10 ft. EL=20 ft. EL=120 ft. 50 ft. has an EL of 50 ft. 50 ft. of 15% compressed flex has an EL of 100 ft EL in Feet 41

41 It s the Fittings that Matter The Most Most of the friction loss occurs at elbows, Ys, and other fittings. 42

42 Equivalent Length (EL) ACCA s Manual D assigns an EL to every type of fitting used in a duct system. If a fitting has an EL of 35, it has the same resistance as 35 feet of straight pipe. 43

43

44 From EL to Total Equivalent Length T.E.L. Total Equivalent Length (T.E.L.) is: the sum of all the individual ELs of the fittings and the length of the ducts along the air s longest path from the return grille through the supply grille. As a rule, you need to keep your T.E.L below 300. It is not: The sum of ALL the fittings in the duct system. Not necessarily the longest path in terms of distance, but the longest path in terms of restriction. 45

57 The Kinked Hose Syndrome

58 hy Do We Hang Ducts in Attics? 59

59 Duct Design Rules 1. Don t do stupid stuff 2. Pick a unit that can deliver required CFM at expected pressure 3. No 90 degree turns 4. Stretch the flex 5. Don t squish the flex 6. Use large return grilles and return ducts 7. MEASURE AIR FLOW 8. If you are counting: keep TEL below 300 feet 9. If using a Ductulator, use a.06 or.08 friction rate for design purposes. 60

60 DUCTED MINI-SPLIT DESIGN The School of Hard Knocks A 18K DHP was installed first Then, we added a 9K mini-ducted variable refrigerant heat pump. What could go wrong? 61

61 DHP System Design Use an appropriate number of indoor heads o In most homes, one head per floor is enough An optimal system often consists of: o 1 DHP in the main living area, +1 smaller unit in the master suite o 1 DHP in the main living area, +1 ducted minisplit serving bedrooms o 1 DHP in the main living area, plus small electric resistance heaters in the bedrooms o If using ER heaters, use smaller units (750w), control with digital wall T-stats 62

62 DHP System Design Orient heads to take advantage of throw and mixing o Place in largest, most open areas o Orient to blow down central hallways In rooms with high ceilings, place DHP < 8 off the floor to minimize stratification effects Don t set units set in Auto mode, leave in heating or cooling Set fan speed to auto fan, if lower capacity and efficiency will drop. 63

63 Avoid Control System Mistakes

64 Thermostats/Controllers: Not DUCTED MINI-SPLIT DESIGN What You re Comfortable With 65

65 DUCTED MINI-SPLIT DESIGN The School of Hard Knocks Perfect airflow flow in each room What could go wrong? 66

66 FUNCTION DUCTED MINI-SPLIT 42 and DESIGN Other Settings jjj Setting the unit to sense temperature at the T-stat: Function 42 has to be set to 01 and the t-stat icon has to appear on the screen High Insulation setting needs to be activated 67

67 Where Fans and Controls Collide 68

68 Controller pitfalls explained 1. If using a wall-mounted controller, make sure it senses temperature at controller and not at air handler 2. If there is an option for efficient home, ensure it is selected. Set to High Insulation 3. Always set to high insulation setting 4. Read the manual 69

69 Commissioning 1. Put system in high heat or high cool mode if available 2. Measure external static pressure 3. Measure delivery at each register (if you have a flow hood) 4. Measure temperature gains 5. Conduct a duct leakage test if applicable 6. Check refrigerant charge against published values. 70

70 Summary Why would a controller sensing temperature at the air handler affect efficiency? How can you check where the temperature sensor is on most controller models? 71
