WSHP System Control and Optimization Part 4: Why Waterside Economizing Might Not Improve Efficiency

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.

Introduction to Water Source Heat Pump Systems Part 3: Basic Operation

WSHPs operate similarly to traditional air source heat pumps (ASHPs) in that they transfer heat rather than creating it from a combustible fuel. Both incorporate a refrigeration cycle to facilitate heat transfer and both include a valve to reverse the cycle, depending on whether the unit is in heating or cooling mode. The primary distinction between WSHPs and ASHPs is….
