When multiple demandsare to be made upon the stored heat, the user enters thehighest minimum temperature demanded.is the highest temperature that the cooling fluid canachieve and still provide cooling at the COOL-SUPPLY-RATE.is the difference between the maximum operating temperatureof the hot water storage tank and HTANK-BASE-T. The maximumoperating temperature is the highest temperature that can beachieved while storing energy at the HEAT-STORE-RATE (seeFig. V.2).For example, a boiler is capable of delivering energy at theHEAT-STORE-RATE to a hot water storage tank at 175°F (maximumoperating temperature). If water withdrawn from this tankfor space heating must be delivered at a minimum of 140°F(i.e., HTANK-BASE-T), the user specifiesHTANK-T-RANGE ; 35.0is the difference between CTANK-BASE-T and the minimumoperating temperature of the cold water storage tank. Theminimum operating temperature is the lowest temperature thatcan be achieved while cooling the tank at theCOOL-STORE-RATE (see Fig. V.3).V.74 (Revised 5/81)
