.Buildings.Fluid.Chillers.Examples.ElectricEIR_HeatRecovery .Buildings.Fluid.Chillers.Examples.ElectricEIR_HeatRecoveryExample that simulates a heat recovery chiller operating in heating mode, i.e., tracking a hot water supply temperature setpoint. The chiller efficiency is computed based on the condenser entering and evaporator leaving fluid temperature. A bicubic polynomial is used to compute the chiller part load performance.
