SUMMARY This article covers the basics of head pressure controls in chiller systems. RESOLUTION Attached article summary: Condenser capacities are based, in part, on TD (temper-ature difference) between the ambient and the refriger-ant condensing temperature. As the ambient falls, and the TD increases, the condenser capacity will increase.For example, a condenser rated at 150,000 Btu/h […]
