A wider design ΔT (temperature difference) in a small chilled-water system can reduce flow rates, which in turn decreases pump energy consumption. This can lead to significant energy savings and lower operating costs. Additionally, a wider design ΔT can also reduce the required chiller capacity, resulting in lower first costs and smaller equipment sizes. However, it’s essential to carefully evaluate the trade-offs between flow rates, pressure drops, and heat exchanger performance when designing for a wider ΔT.
