The heat exchanger was then tested using non-LDRD project funds. The heat exchanger test stand was constructed and demonstrated. A description follows. The test stand is shown in Figure 1. The mass flow controller sets the nitrogen flow entering the cold side of the exchanger.
Chilled water is provided from a building supply.
Heat Exchanger Test Stand. On the left is the computer used for data logging. Transmitting gauges provide differential and inlet pressures on both sides of the exchanger. The silver cylinder to the right is a 0-1000 slpm mass flow controller connected to the house nitrogen supply. Tees at each connection allow for pressure taps and thermo-couples to monitor temperature, pressure, and pressure drop on each side of the exchanger.
