Kennel Ventilation – Supply and Exhaust
Properly designed ventilation can reduce or eliminate odors, reduce bacteria build-up, and help keep dogs smelling fresh and clean. Your pets will be happier and you’ll spend less time drying and deodorizing floors. If you have trouble understanding the information in this article, email us at Sun Hill Pet Supply on the web.
Regardless of the size of your facility, ventilation will play an important role in visitors’ first impression of the kennel. Simply put, ventilation is controlled, air movement is directed.
- air exchange: Change all the air in the room four to six times an hour. Measure the room volume in cubic feet, multiply the result by four, five, or six, then divide by sixty to find the air volume, cfm (cubic feet per minute).
- Exhaust pick-up point: Most dog house odors are generated by dogs, so keep your exhaust pick up point less than 30 inches to ensure odors are pulled down, away from your nose. However, not less than twelve inches from the floor to prevent cleaning water from entering the ventilation system.
- How many exhaust pick up points: Multiple points throughout the room ensure air movement has a chance to circulate properly. Remember we’re not talking about air ducts going back to your heating system, we’re talking about exhaust vents to remove air from the room.
- Air supply: Install your air supply vents, high up in the room. This allows air to flow down over the exhaust pick up points, which pulls the odor down and away from your nose. Remember, the supply air must be filtered and tempered, (hot or cold), the outside air must not be raw. Your HVAC contractor can install a unit that supplies enough fresh air to the ventilation system to meet supply requirements.
- Position of air supply and exhaust vents: Place the supply vents in the form of pipes leading into or under the walls at the mesh passages and behind the exhaust pick up points. If the heating source is a “hot air” system, one-third of the hot air should be brought in through the floor and two-thirds through the ventilation ducts.
- Type and design of exhaust fan: You want to use blower with centrifugal wheel as air mover. Fans and blowers that use blades like window fans will not be able to overcome the static pressure created by the ductwork required for multiple pickup points.
- Take the shape of the blower: Multiply the cfm you calculated in step #1 by 1.5 to create a safety factor to insure your adequate air, then select the exhaust blower to move at ½” or more cfm of static pressure. Static pressure is resistance. Air flow, usually through a duct system is created.
- Duct sizing: A higher air velocity in the system will ensure better air flow so the size of the ducts will increase to around 2000 fpm (feet per minute) air velocity. The easiest way to size is to determine the size of duct needed to handle the total air flow, then, install that size as the primary duct throughout the building. Determine the number of drops you want and divide the area of the primary duct by the number of drops. Each droplet is then sized for that area. Use this formula to determine the primary duct size: (cfm / 1500fpm) x 144 = duct area in square inches
Formula Info: · http://www.Grainger.com is a great source for blowers.
· Area of a circle: Radius squared times 3.14 ( [r x r] x 3.14) Example of Area of 3″ Round Duct: (1.5 x 1.5) x 3.14 = 7.065 square inches
· Convert square inches to square feet: Divide square inches by 144. From the example above, 7.065 square inches divided by 144 = .049 square feet.
1. A kennel room is 20 ft x 15 ft with a ceiling height of 10 ft: 20 x 20 x 10 = 4000 cubic feet
2. Five (5) air changes per hour = 4000 x 5 = 20,000 cubic feet
3. Determine cfm (cubic feet per minute) 20,000 / 60 = 333 cfm
4. Safety Factor Air Flow: 1.5 x 333 = 500 cfm
5. From Grainger’s: http://www.grainger.com/Grainger/items/2C946 This blower moves 537 cfm ½” constant pressure, and is only $165.38 and can be plugged into most outlets.
6. Primary duct size in square inches: (500cfm / 2000 fpm) x 144 = 36 square inches of duct. You can use 6′ x 6″ square duct or 7″ diameter round duct.
