Outdoor design temperature. If you're performing a heat-loss calculation to size heating equipment, you need to perform the calculation for the worst-case condition: namely, the coldest night of the year. (Because the coldest condition usually occurs at night, a heat-loss calculation does not consider solar gain through windows.)

Vertical Conveyor Ovens are designed to minimize use of factory floor space. They utilize vertically moving trays and are ideal for heating or curing parts within a work cell. Heated parts are periodically removed from a tray and the tray filled with cold parts to pass through the oven. Trays can be indexed or move continuously.
Recall that the formula for daily heat loss is: Heat Loss (BTUs h) = Area (ft2) × Temperature Difference (oF) Rvalue(ft2 oF h BTUs) × 24 h day. Thus, theoretically, we would need to perform this calculation for every day of the 365-day calendar year. For example, if the average outside temperature were to be 35°F, 32°F, 28°F, and so on for ...
The formula for calculating heat loss is: Heat Loss = U-value x Area x Temperature Difference.
