Engineers seeking to meet the waterside economizing requirement of ASHRAE 90.1 - 2013 do not necessarily have to specify multi-zone commercial water source heap pumps with integral economizers. In fact, doing so may undermine efficiency.
Read MoreApproach temperature and an AHRI 400 rating are probably the two most critical factors when it comes to selecting a plate and frame heat exchanger for maximum efficiency and guaranteed performance. Do yourself and your client a favor and…
Read MoreWaterside economizing typically involves the transfer of BTUs from an open loop cooling tower system to a closed loop chilled water system. Since these two hydronic systems must remain separate so we do not foul the chilled water systems, a heat exchanger is required to prevent mixing of the fluids, but what type of heat exchanger should you choose?
Read MoreIn our last blog we discussed heat exchanger piping on the cooling tower/condenser water side of a system with integrated waterside economizing to meet ASHRAE 90.1. Today, we’re going to tackle the chilled water…
Read MoreWaterside economizing relies on cold water from the cooling tower (aka condenser water) to absorb some or all of the heat from inside the building. In typical waterside economizing applications, plate & frame heat exchangers are used to…
