Overall HVAC System
The figure below illustrates the schematic HVAC system which provides for heating and cooling of the Intelligent Workplace on the fourth floor of Margaret Morrison Carnegie Hall (MMCH). The hot water is supplied from the campus steam network into the second basement of MMCH. The campus supplied steam is converted into hot water in the second basement by the heat exchanger which is then pumped onto the 4th floor mechanical room. The hot water in the 2nd basement is 180 F and the supply water in the 4th floor is 178 F.
The hot water is pumped from the 2nd basement to the 4th floor mechanical room by the hot water supply pump located in the 2nd basement. There are two hot water supply pumps in order to alternate the usage of the pumps in situations of breakdown or overload of one of the pumps.
The chilled water is supplied from the campus chilled water network which is pumped onto the 4th floor. The temperature of the supply water is approximately between 40 F – 42 F.
