Calculation Basis |

The water-ground pump flow rate is measured by the following formula:
The water-ground pump flow rate in kilograms is measured as follows.
c: The specific calorific power is:
As the probes generally operate on glycol/water mixture and glycol decreases the calorific power, we calculate based on a simplified method with the following value:
The heat quantity (required collection power) and the temperature difference are known; we need the circulated water-ground quantity. Therefore, we transform the formula as follows:
Computation example: Collection power 8 KW = 8000 W, considered temperature difference = 3,4 K
m = 2353 kg is the water-ground quantity, circulated/hour = volumetric flow rate = 2353 L/h |
