Evaluation of Water to Water Heat Pump Model in Energy Plus Using Measurement Data
The purpose of this work is to find a protocol and a model that describes the behavior of a geothermal heat pump in an actual environment in order to determine the actual power consumption and capacity of the device. This paper focuses on the use of field measured data to derive the performance of the heat pump. The equation fit model is used as it does not demand very detailed input. The model employs the condenser and evaporator inlet temperatures as input data. The heat pump provides heating and cooling for the living and working area of the zero energy lab which is 1200 sq ft building and designed to intimate a small residence., and both cooling and heating were investigated. A model was generated for each case. Long operation periods were sought for model generating so two experiments were set in different seasons to collect the data for each mode and each experiment lasted for 10 days. Model results showed an error range of ±10% for the unit capacity and power consumption.
