Chapter 1
Heating, Ventilating, Air Conditioning and Building Systems Fundamentals.
This chapter will review the basics of heating, ventilating and air conditioning (HVAC) and buildings as related to energy engineering.
DEGREE DAYS
Degree days are the summation of the product of the difference in temperature (T) between the average outdoor and hypothetical average indoor temperatures (65F), and the number of days (t) the outdoor temperature is below 65F. Therefore:
Degree days divided by the total number of days on which degree days were accumulated will yield an average T for the season, based on an assumed indoor temperature of 65F. To find the average outdoor temperature of the season, this figure must be subtracted from 65F.
Example Problem 1-1
If there are 6,750 degree days recorded over a heating season of 270 days, what is the mean outdoor temperature for that season?
Answer
The average outdoor temperature can now be found, since
