In this case, it may be necessary to add or increase the size of the mixing tank in the return line. If a chiller is attached to an on/off load such as a process load, it may be difficult for the controller to respond quickly enough to the very rapid change in return solution temperature if the system has only the minimum water volume recommended. To reduce heat loss and prevent condensation, insulation should be applied. The selected chiller can operate at these temperatures, but has a minimum flow rate of 106 gpm (6.6 l/s). Supply air movement may draw debris into the condenser coil, blocking spaces between coil fins and causing coil starvation. This location allows the building to act as a buffer to slow the rate of change of the system water temperature. Mfg. Therefore, as a guideline, ensure the volume of water in the chilled water loop equals or exceeds two times the evaporator flow rate. If the cooling load is less than 50 percent of the system capacity, Chiller 1 would be able to satisfy the entire call for cooling. The dual mode control functionality is integrated right into the chiller. Get in-depth information on Trane RTAF200 Chillers including detailed technical specifications.
