DETERMINING GROUND LOOP RESISTANCE WITH GROUND SOURCE HEAT PUMP MONITORING DATA

摘要

In some embodiments, a method operates a heat pump that uses a ground loop to perform heating or cooling in a site. During the operating of the heat pump over a time period: the method measures a first series of measurements of a ground loop water flow rate by the heat pump; a second series of measurements of a ground loop fluid temperature for the heat pump; and measures a third series of measurements of a local soil or deep earth temperature. The first measurement, the second measurement, and the third measurement are outputted where a ground loop thermal resistance value is calculated for the heat pump based on the first measurement, the second measurement, and the third measurement.
