bulldog exhaust systems

Properly designed ventilation can reduce or eliminate odors, reduces the accumulation of bacteria and help maintain the fresh smell and clean the kennel. Your pet will be youÂ'll happy and spend less time trying to dry the soil and remove odors. If difficulty understanding the information contained in this article, please, please contact us on the Web of Sun Hill Pet Supplies.

Whatever the size of the installation, ventilation plays a key role in the first Kennel impression visitors. In short, the ventilation is controlled, directed airflow.

Design Basics:

1. Air exchange: changing all the air in rooms of four to six times per hour. Calculate the volume of space in cubic meters, multiply the result by four, five or six years, then divide by sixty to find the volume of air in CFM (cubic feet per minute).
2. Escape from collection points: most of the smells of the kennel will create the same level as dogs, if the position of his escape have points of less than 30 inches for ensure odors are pulled down, away from his nose. However, no less than twelve inches from the ground to prevent the wash water from entering the ventilation system.
3. Exhaust How to collect points: several points throughout the room to ensure the flow of air has a chance to circulate properly. Recalls not speak of the return air system of heating, air vents weÂ're speaks to remove air from the room.
4. Air Supply: Install your air vents high in the room. This allows air to flow down to select the points of escape, thus pulling down and odors away from your nose. Remember that the air supply must be filtered and tempered (heated or cooled), not thought out of air. Your HVAC contractor can install a unit that provides enough clean air the ventilation system to meet supply needs.
5. Position of supply and exhaust air: air vents feeding station in the corridors and escape routes have points on the walls and pipes from the walls. If the heat source is a  "Aira hot "system, with one third of the hot air entering the floor and introduced the two-thirds through the vents in the hallways.
6. Type and design of the exhaust fan: YouÂ'll want to use a blower with a wheel as the engine of air. Fans and blowers that use of a leaf similar to that of a window fan wonÂ't be able to overcome the static pressure created by ducts need for multiple points
7. Size Fan: Create a safety factor to multiply the CFM they have calculated in step # 1, 1.5 to keep moving enough air, then select the exhaust fan to move the amount of CFM to  ½ "static pressure or greater. The static pressure is the resistance to airflow, usually created by the duct system.
8. The size of the duct high velocity air in the system will ensure good circulation air if the air ducts of about 2000 feet per minute (fpm) air velocity. The simplest method Sizing is to determine the size of the pipe needed to address the total air flow, while the size of the facility that the main channel, the entire building. Determine how many drops as you want and split channel Primary region by the number of drops. Each drop is then the size of the area. Use this formula to determine the size of the main conduits: (PCM / 1500fpm) x 144 = duct area in square inches

Form: a http://www.Grainger.com · Is a great source for fans.

· Area with a radius of a circle squared times 3.14 ([RXR] x 3.14) Example 3A region "pipes round: (1.5 x 1.5) x 3.14 = 7.065 square inches

 · square feet convert square inches: divide by 144 square inches. In the example Previous 7.065 square inches divided by 144 =, 049 square feet.

Example:

1. Breeding room is 20 feet x 15 feet with a roof 10 feet tall, 20 x 20 x 10 = 4,000 cubic feet

2. Five (5) air changes per hour = 4000 x 5 = 20,000 cubic feet

3. Determine CFM (cubic feet per minute) 20000 / 60 = 333 CFM

4. Safety factor of air flow: 1. 5 x 333 = 500 CFM

5. Grainger: http://www.grainger.com/Grainger/items/2C946 This fan moves 537 CFM at a static pressure ½ ", and is only $ 165.38 and can be plugged into most outlets.

6. Channel main square inch (500cfm / 2000 ft / min) x 144 = 36 inches square duct. You could use 6Â'x 6A "square duct, or 7 a" diameter round duct.
