The System

Small Duct High Velocity (SDHV) Heating & Cooling
· SpacePak delivers uniform, year-round comfort, with fewer of the unwanted challenges common to other central heating and air-conditioning systems. Making sure there are:
· No Major Renovations · No Loss of Usable Floor Space · No High Energy Bills · No Unsightly Components
· Simply quiet, cost-effective comfort for virtually any home or building, regardless of the structure’s design, age, size, or construction type.
· SpacePak is an air distribution system which uses a principle known as aspiration – as the air stream enters the room, it creates a gentle mixing of air in the room to provide thorough, comfortable draft-free air circulation.
· SpacePak eliminates stratification with a minimum floor-to-ceiling temperature difference.

68

RETURN

Locate and Roughing in the Return
· Central Location (Hallway/Foyer) · All Equipment Can Fit through the
Return Hole Cut Including the Air Handler · Be Sure to Have More than Enough Return Air for the System · Do Not “Skimp” On Return. You cannot have too much.
69

RETURN
Return Basics
· Air Mixing vs. Air Change · Less Return Air Volume · Cooling And Heating By Temperature,
Not Volume · One Central Return Is Sufficient · Multiple Returns Are Okay · Smaller Return Air Duct Than
Conventional · You can never have too much return
air!!!!
70

RETURN
Return Basics
· Size Return in each location for less than 500 FPM (similar to conventional) · Size Return in each location for a total -.25″ static or less including the filter · Install at least One 90-degree elbow (this will aid in the abatement of unwanted noise) · Return Box must be lined with sound attenuation material (also for noise abatement) · Size transfer grills for the CFM and Free Area (use standard duct sizing chart)
Note: If return creates to much “suction” over -.5″wc this suggests the lack of return air and creates the potential to cause issues with proper condensate draining resulting in faults or water damage.

RETROFIT
RETROFIT CONCIDERATIONS!
· Just because a 2-, 3- or 5-ton unit was installed DOES NOT mean the same unit can go back in without looking at the existing system, its layout and available CFM’s
· IT IS STILL GOOD TO DO A LOAD CALCULATION. Many times, if a system has been installed for many years there may have been considerable efficiency improvements to the home. Ex.(the house may no longer require 5 tons of cooling due to window, roof and insulation upgrades)
· Count the total existing supply terminations · If the blower in the existing system runs (even if the condenser does not) turn it on and take CFM readings at ALL outlets. Confirm
total available CFMs are equal or greater than the amount required for the new system. (220-250 CFM PER TON) · Verify, when possible, the main trunk “inside” diameter and overall length · If the evaluation of the existing system reveals anything that may lead to the new system not operating properly without
improvements, please note the specifics on your installation proposal.

· 6-7 outlets minimum per Ton on an AC-only · In cooling only above 5000′ use 8 outlets per ton and above 6500′ use 9 outlets per ton · 7-8 outlets minimum per Ton on a Heat Pump System (due to higher coil pressures) · 2,000 BTUs per outlet (fully rated) in Cooling at 37 cfm · 3,000 BTUs per outlet (fully rated) in Heating at 37 cfm · Outlet placement in a room · Room-by-room load Calculations to ensure the number of outlets in a room · Best length of a duct run (includes sound attenuator) · Maximum length of a duct run (9′ to 15′ this length includes the 3′ sound attenuator) · If the termination “hole” is closer to the trunk than 9 feet you can also loosely coil the supply (not tight)
113

SUPPLY TUBING
Best Length of Duct Run
· Best length to balance the outlets run: 9 to 15 feet (with attenuator) · Shorter than 9 feet work with duct orifice balancers · Longer runs work if more runs are added to make up for the CFM lost · 10% rule (after 15′ of supply run you lose 10% for every additional 5′) Loss of CFM and BTU’s · CFMs directly affect the amount of Btu’s delivered
114

DON’T DO THESE · Place in traffic patterns (room ceiling & floor corners, and behind door swings are ideal) · where it will blow on someone (air can travel 15+ Feet) · where it will blow on something that will move (example; curtains) · Never block an outlet (reduction of airflow can reduce system performance) · Have at least 6 inches from the center of an outlet to a wall
· If an outlet is mounted in the floor, a ¼” screen can be used to prevent the introduction of foreign objects into the system.
· Ceiling, sidewall, or floor are all ok! Aspiration will work anywhere!!!

layout with at centrally

located return, this system

would need no “extra

balancing” based on our load

÷

calculations and duct design

chosen.

Note: Since this is a heating and cooling system resulting in being slightly oversized for one setting you can use the variable speed blower to ensure the air flow match and btu delivery without the concern of unwanted N noise.

4” Hole Saw
When installing in a standard sheetrock ceiling be sure to use a 4″ hole saw other ceiling and floor material may require a slightly different installation processes.
138

OUTLETS
Installation of termination plate and mounting clips
· The sound attenuator is usually attached to the termination plate at this time · Altering the clips or hole size may be required in some applications for proper fastening as different installations may
require adjustments – this is all considered ok as long as you are not restricting air flow (should not have any effect on system performance)

Showing a common supply wall and common return air

If we were standing in this picture, all windows would be at our back.

APPLICATION
Hallway Installation
· Notice the best place for outlet termination is in the center of the hall
· Rough-in plates were used in this installation to ensure proper locations of the supply terminations
144

Showing horizontal wall terminations
145

This installation shows ceiling terminations. 9 – 10 runs per ton were used in this installation to ensure that air noise would not be an issue due to the lack of natural sound deadening material (full carpets, low ceilings, etc.).
146

This install used exterior wall terminations, the main trunk was actually rectangle and located in the floor. The supplies were run up the outside walls between the windows and out creating a thermal curtain. This rooms cooling load was 42kbtu.
147

This install shows the use of no

termination plates, the cabinet

maker made holes and the

contractor attached to the back

of the top plate. Notice the slight

angle to the top plate this will

allow the air to travel under the

timbers and across the room.

APPLICATION
Spot Conditioning
Great for · areas where it would be financially
exhausting to condition the entire space · kitchen prep lines · Assembly lines
· Gives a great commercial look · You can run fewer outlets per ton due
to the loss of restriction applied by the normally installed supply tubing · Generally, 4-5 outlets per ton will work here
149

ZONING
Zoning Basics
· When zoning with SpacePak a staged or fully inverter condenser MUST be used. · In a multi zone system the smallest zone must be of the same size or larger output
then the lowest turned down capacity of the compressor being used (ex: if the inverter condenser turns down to 12kbtu then the smallest zone on the system must be capable of handling that capacity 1-Ton) · When using multiple zones, the controls on the J-Series air handler will allow you to match the air flow to the specific needs of the system. · During zoned system installation and layout be sure to follow all duct design rules. · DO NOT UNDER ANY CIRCUMSTANCES USE AN AIR BYPASS OF AN CONFIGURATION IN ANY SPACEPAK SYSTEM!
