Answers |

 |
As a rule of thumb, 30 air changes-per hour are needed. |
Is there natural shading?
|
|
Adjust air change requirements. |
| Is there tinted glass or blinds? |
|
Adjust air change requirements. |
Is there a southern or northern
exposure? |
|
Adjust air change requirements. |
Is the solarium open to the rest of the
house?
|
|
Consider the air change requirements based on the larger area. |
Fan size calculation:
Width x Length x Height x Air change requirements / 60 (minutes)
= cubic feet per minute (CFM)
Example:
Solarium size: 8x14x8 = 896 Cubic feet x 30 (airchanges)
= 26,880 (Airchange
requirements per hour) / 60 (minutes) = 448 CFM
A 9" Vent-Axia fan would handle it (467 CFM capacity). But
a 12" fan would be more appropriate as it can move 647 CFM
on low speed and is quieter.
Location of fan:
Can the heat build up be utilized in between seasons (Fall & Spring ) ? YES
|
 | 1) Close all windows
2) Open door to house
3) Bring fresh air in on low speed
The fan will create a positive pressure forcing the air into the house. |
Each fan should be accompanied by a 3-speed reversible switch (controller) and a line voltage,
reverse acting thermostat (automatic operation).
The fan is excellent for Hot-tub areas or indoor swimming pools (use a dehumidistat). Always advise how many meters of 5-connector cable are required (needed between controller and fan).
