If you don't know, it's annoying. Do you know the flow rate of the brine loop? And just to check, its temperature entering and leaving the heat pump at the moment?
Characteristics of the brine circuit
- flow rate: between 800 and 1.500 l / h (all the water stored in the soil is then used a little more than once per hour) and therefore 13 to 25 l / minute
Is the flow variable? You have an idea at the moment, the control panel gives the value (it should be maximum).
And heat pump inlet and outlet temperatures on the brine side at this time?
I put here the different parameters:
Regarding my CAP, I get the following COPs (last readings on the CAP on-board computer),
about:
- 7,2 (16 kWh) (21 ° glycol water)
- 6,8 (15 kWh) (… 19 °)
- 6,3 (14 kWh) (… 17 °)
- 5,9 (13 kWh) (… 15 ° or 14 °)
- 5,4 (12 kWh) (… 13 °)
- 5 (11 kWh) (… 12 ° or 11 °)
- 4.5 (9 kWh) (… 11 °, 10 ° or 9 °)
- 4 (9 kWh) (… 7 °)
- 3,7 (8 kWh) (… 5, 4 ° or 3 °)
- 3,2 (7 kWh) (… 2 °, 1 ° or -0 °)
Characteristics of the brine circuit
- flow rate (not variable): between 800 and 1.500 l / h (all the water stored in the soil is then used a little more than once per hour) and therefore 13 to 25 l / minute
- pressure: from 1 to 1,5 bar
- pipe diameter: inside: 2,5cm / outside: 3cm
Current temperatures:
* heat pump outlet: 45 °
* brine entry: 0 °
Thank you for your help !
