www.hi-velocity.comHi-Velocity System DesignThe higher water temperature will increase system efficiencies,and the water tempering valve will reduce the risk of scalding.Since some areas have specific regulations regarding combosystems, please check your local building code for details onwater tank temperatures, tempering valves, and pump timers.The following section is basic information needed for thedesigner. If not done already, this section should be readthoroughly before beginning installation.Due to the lower air temperatures, when running the ductworkin an unconditioned space, the main plenum must be insulatedand vapour barriered. Extra insulation should also be used inorder to maintain a reasonable leaving air temperature at thevents.IMPORTANT: A minimum of 4 (four) HEoutlets or 8 (eight) 2” outlets per ton isrequired for all Hi-Velocity HE-Z fan coils.Any combination of 2” and/or HE outletscan be used to meet this minimum.Combination Hi-Velocity and RadiantLocationThe multi-positional fan coil can be installed in many differentconfigurations. The fan coil can be located in a Vertical, Horizontal,or Counter-Flow position.Heat Loss/GainTo size a Hi-Velocity System for a residence/commercialspace, it is necessary to have an accurate heat loss/gain donefor the structure. This will ensure the proper equipment is usedfor cooling and heating.A heat loss/gain is done for each room, which will give a totalBTUH load for the structure.NookKitchenBathBed #1Bed #2Dining Rm.FoyerFamily Rm.Master BedM.Bath/WICTotalsBTUH ,78645,757One of the benefits of using a hydronic system is the versatilitythat you have when designing the heating system. Radiant floorheating is an excellent system, but it does have limitations. Youcannot have cooling, air filtration, and humidification with astraight radiant heating system. Similarly, sometimes a forced airsystem is not the only option available for a house, especially ifit has a lot of ceramic tile or concrete floor areas.In the sample house included, radiant floor heating may beunable to meet the requirements to heat the nook. With theHi-Velocity System, we can heat this room, but would have anexcessive number of outlets in a small area.Fig. DES-01 - NookExampleRoom: NookHeat loss: 8,326 BTUHNumber of Vents: 4Table DES-01 - Example Data for Fig. DES-02Room NameModule DESHi-Velocity System Design (2/10)BTUH 9328,579The design factors used to achieve this heat loss/gain areshown on Fig. DES-02.It is in rooms such as this that a hybrid system of both radiantheating and the Hi-Velocity System would be the optimumsystem to provide comfort conditioning. This will provide thehome owner with good indoor air quality, and warm floorcomfort (not as effective if carpet is laid down).A common approach to a hybrid system is to heat thebasement with radiant tubing. The main floor and 2nd floorif applicable would be heated with the Hi-Velocity System. Afew outlets can also be placed in the basement to provide aircirculation, and supplementary heating if required.Low Water Temperature SystemsWhen running Hi-Velocity Systems from a low watertemperature system (e.g. A hot water tank), care must be takenwhen designing and installing the system. Due to the lowerwater temperature there will be less BTUH’s and therefore alower supply air temperature, it is imperative that the watertemperature is known at the design stage. If possible the highesttemperature setting should be used, and a water temperingvalve installed for the domestic use.-2- 1995-2020 Energy Saving Products Ltd.
www.hi-velocity.comUnit SelectionA room (Nook) that has a heat loss of 8,326 BTUH and a heatgain of 5,233 BTUH will need 4 vents.With the total load known for the structure, it is now possibleto select the proper Hi-Velocity unit (Specifications - Pg. 9).Table DES-02 – Selected Fan CoilSelected fan coil:Entering Water TempHouse Heat Loss:House Heat Gain:Minimum Outlets:Maximum OutletsSelected CondenserExample:4 x 3,146 BTUH 12,584 BTUH(12,584 8,326 Heating requirements satisfied)HE-Z-70 H180 F45,757 BTUH28,579 BTUHHE 102” 20HE 162” 322.5 ton4 x 1,154 BTUH 4,616 BTUH(4,616 5,233 Cooling requirements not satisfied)The heating checks out but the cooling doesn’t in thisexample.

This is usually caused by a large appliance load or anexcessive amount of windows. If this happens you will have to usethe greater number of outlets to provide both heating and coolingfor the room. The vents have dampers and can be adjusted forindividual room comfort. In cooling mode the outlets must be inthe fully open position or there will be a loss in performance andthe efficiency of the system.2111121231-3- 1995-2020 Energy Saving Products Ltd.

Module DESHi-Velocity System Design (5/10)www.hi-velocity.comDrawing the PlenumSystem LayoutFor this layout we have chosen to use a Main Plenum with a56/44 bullhead tee split. On one side 14 vents will used, while 11will be used on the other. This is allowable as we can use a BullHead Tee up to a 60/40 split. If the split is greater than 60/40,a Branch Tee should be used instead of the Bullhead Tee. SeeModule DUC - Installing Plenum and Branch Duct for InstallationInstructions.With the total vents known, the layout of the Hi-VelocitySystem can now be done. Start with individual vent placements (ifyou have not already read the section on Vents in System Design,please do so before starting). Then place the main plenum so theflex runs will be the shortest length possible. With the plenumplaced, the flex runs can be drawn connecting the vent outlet tothe main plenum.With a 56/44 split we will be able to reach all vents usingstandard 10’ and 15’ flex runs. If you have to extend the flex runslonger than 10’, reference Table DES-05 for adjustment factors.Drawing Vent PlacementTo demonstrate a vent layout, we’ll place 4 two inch vents toproperly condition the Nook (Fig. DES-03). From Table DES-03we calculated that the Nook has a Heat loss/gain of 8,326/5,233,which will require 4 two inch vents to satisfy heating and coolingrequirements.Table DES-05: De-rating ValuesHE-Z SeriesTubing LengthAdjustment FactorFig. DES-03 - Placing Vents: Nook10’0%15’10%20’20%25’35%The main plenum we choose to use is 8”, it is not requiredto use 8” for the whole run. If space or cost is a concern, themain plenum can be reduced down to a smaller size. If reducingthe plenum, reference Table DES-06 for allowable length andmaximum number of vents for the size chosen. Never reduce ata bullhead tee, always reduce after the bullhead tee or you canlose approximately 20% of your airflow.4 Vents distributedevenly throughoutthe space.Table DES-06 – Duct Reduction# of 2”(51mm)Vents4612183050DuctSize4” (102mm)5” (127mm)6” (152mm)7” (178mm)8” (203mm)10” (254mm)With this room 3 two inch vents would have satisfied theheating requirements, but would not satisfy the coolingrequirements. For the nook we need 4 two inch vents for cooling,so 4 two inch vents must be placed in the nook.

In coolingmode the outlets must be in the fully open position.# of 9m)50’(15.24m)60’(18.29m)70’ (21.33m)100’ (30.48m)Drawing the Flex RunsOnce the vents and plenum have been drawn in, the two maynow be connected with the flexible branch duct. The minimumflex run is 10’ (3.05m) and the maximum is 25’ (7.62m)The outlets should be located where it is considered to be a“low traffic area”. Typical areas are in the corner of a room, orto the side of a window or door. When the vents are properlylocated, the home owner can expect to have a nearly draft freehome.Once all the vents have been placed in each room, the mainplenum can now be drawn. Figs.

Module DESHi-Velocity System Design (7/10)www.hi-velocity.comPSB Zoning Design (HE-Z Series Only)Please note: The HE-B Series Fan Coils can be used for zoning but may require the use of by-pass dampers or dump zones.PSB ZoningThe Branch Take Offs easily form to ducts in the 6” to 10” range;extra care must be taken with smaller sized ducts to ensure aproper air seal. For tee reductions, keep the tee to the full ductsize, reducing only after the tee. Keep the length of the smallerduct sizes to a minimum, since the duct loss is much higher. Ifa hole saw will be used to drill the branch take-off holes, metalducts are recommended to be 28 gauge steel.The PSB Board is compatible with most Forced Air ZoningPackages. Zoning control panels with a Recirculation FanOption are strongly recommended, so as to utilize continuousair circulation for optimal Indoor Air Quality (IAQ) and EnergyEfficiency. Independent testing has shown that utilizing therecirculation fan with the Hi-Velocity Systems VFD motor reducestotal energy usage. This is due to less on/off cycling of AC andHeating equipment by constant de-stratification of the air.Whichever method of zoning layout is utilized, it continuesto be important for Indoor Air Quality that a certain amount ofair is by-passed through each zone. This air recirculation is alsoimportant for Energy Efficiency, and even though the zone maynot be calling for it, the recirc air will aid in overall living comfort.Quick acting, spring shut dampers are not to be used with thePSB Board. Instead, it is suggested to use a slow acting electronicdamper, which gives the PSB controller adequate time to adjustto variations in duct pressure.Perimeter Loop (Fig. DES-06)When designing the perimeter loop, first determine the systemload and individual zones. Locate the fan coil and vent outlets asper Page 5. Design the Perimeter Loop with the proper diameter8” or 10” duct, as determined by the fan coil unit. Use appropriateplenum duct size around the perimeter of the structure.Layout DesignThere are three basic layout styles to be used with the PSBController: the Perimeter Loop/Branch (Fig. DES-06), the MainPlenum Branch (Fig. DES-07), and the Open Duct standard design(Fig. DES-08).When sizing the branch zone plenum off the Perimeter Loop,use the Zoning Duct Reduction Guide. (Table DES-06). Total theoutlets for each individual zone to determine the zone plenumduct diameter. Locate the tee servicing this zone to minimize thezone plenum duct, and run the plenum where it’ll be possible tokeep the AFD duct to 10’ and 15’ lengths. There is no minimumlength on the Zone Main Plenum run. For maximum lengthallowed refer to the Zoning Duct Reduction Guide (Table DES-06).The Perimeter Loop layout is as the term implies. A perimeterloop of plenum duct is installed in the structure, from therebranch tees are installed for each zone dependant on the zonesize, and a zone damper is installed for each take-off/zone.Main Plenum Branch (Fig. DES-07)The Main Plenum also requires that a comprehensive systemload is completed, zones determined, fancoil and outlets locatedas per this design manual. The Plenum duct is then located todirect the air to the loads at each zone, and elbow and tees canbe located where required, as per this design manual.The Main Plenum Branch method is similar to a PerimeterLoop, in that you direct the main plenum to the area loads,with branch tees directing each zone to the outlets, once againinstalling zone dampers.The zone duct diameter is determined from the duct reductionguide and an appropriate balanced tee installed. Locate the teeservicing this zone to minimize the zone plenum duct, and runthe plenum where it’ll be possible to keep the AFD duct to 10’and 15’ lengths. There is no minimum length on the Zone MainPlenum run. For maximum length allowed refer to the ZoningDuct Reduction Guide.The Open Duct layout is the same concept that is used onPage 6. This method utilizes the branch split and bullhead teesplanning of air flow, with each zone being individually controlled.Each basic layout has it’s typical applications. For example, thePerimeter Loop and Main Branch Layouts are best served doingmulti-zones of 4 or more, with the Open Duct best servicing 2 4 zones. Perimeter Loop works well in a single level application,while the Main branch is better suited for multi-level applications.Open Duct System (Fig. DES-08)The Open Branch layout utilizes this layout on Page 6 in itsentirety, from load calculation to duct location. This methodis best suited when 2 - 4 zones are utilized, by following thedesign manual and duct reduction guide if necessary. You willeither branch or bullhead the tees to 1 or 2 zones, and continuethe plenum to the furthest run, installing zone dampers whererequired.In some installations, it is necessary to reduce the size of themain plenum. Caution must be used when reducing plenum size,since smaller ducts can handle less number of outlets. Also keepin mind that once reduced, the main plenum cannot be increasedagain.-7- 1995-2020 Energy Saving Products Ltd.

VPL Lab ah-Velocity Bats 1 Rev 9/18/14 Name School _ Date Velocity: A Bat's Eye View of Velocity PURPOSE There are a number of useful ways of modeling (representing) motion. . (initial velocity) tool and Go button to launch the cart at a known positive or negative velocity. 4. Change the color of the lines drawn on the graph.
Velocity histogram: Histogram of the velocities of the objects. Range interval: Size of the interval for the Velocity histogram. Show Info shows the maximum and minimum velocity. With this two values the velocity range can be computed. (Max Velocity - Min Velocity). The entered value must be divisible by the velocity range without remainder. 12
an object moving with a velocity of 10 ms 1 and an object moving with a velocity of 10 ms 1 both have a speed of 10 ms 1 . As with speed, for objects moving at non-constant velocity you can consider the average velocity. posit ive 10 m 40 m 10m 10m 10m For an object moving at constant velocity: veloci ty change in displacemen t ti me ta ke n .
Velocity of Adjacent Links - Angular Velocity 4/5 Angular velocity of frame {i 1} measured (differentiate) in frame {i} and represented (expressed) in frame {i 1} Assuming that a joint has only 1 DOF. The joint configuration can be either revolute joint (angular velocity) or prismatic joint (Linear velocity).
The interval velocity function consists of a series of blocks, with each block having a constant velocity, giving the Dix Equation Method several interferences: For each single point in the RMS velocity function, there must be two points in the interval velocity function to constrain the function to a uniform velocity over an
