- •
The work focuses on the variable flow in ground source heat pump systems.
- •
The constant and variable speed circulation pumps in the ground loop are compared.
- •
The constant temperature difference control across the heat pump is studied.
- •
The variable flow affects the energy performance of the heat pump.
- •
The constant temperature difference control offers an attractive energy saving.
