- *********** HEATING ***********
-
- The heating outside design temperature is 10 degrees fahrenheit.
- The heating inside design temperature is 72 degrees fahrenheit.
- The heating temperature differential is 62 degrees fahrenheit.
-
- The heat loss for this building is 79,616 BTU's.
-
- The heating unit must handle 904 CFM's for proper heating.
-
- Any heating unit must be rated as close as possible to the heat loss
- calculated in this study, but not less than that amount.
-
- The above CFM allows an 80 degrees rise in inlet to outlet air temperature.
-
-
- *********** COOLING ***********
-
- The cooling outside design temperature is 95 degrees fahrenheit.
- The cooling inside design temperature is 72 degrees fahrenheit.
- The cooling temperature differential is 23 degrees fahrenheit.
-
- The heat gain for this building is 43,101 BTU's.
-
- This translates into 3.6 tons of cooling.
-
- The preferred cooling CFM is 1,293 CFM's for proper cooling.
-
- For high humidity areas use 1,077 CFM's
- For normal humidity areas use 1,293 CFM's
- For low humidity areas use 1,508 CFM's
-
- Any cooling unit must be rated as close as possible to the heat gain
- calculated in this study, but not less than that amount.
-
- ****************************************************************************
- The writers of the software that was used in generating the above in-
- formation assumes no responsibilities for any losses that may be
- incurred by the use of the above information.
