Heat pump calculators

Open source tools to help with heat pump design and understanding.

Heat exchanger 1

Calculate heat output and COP for a system with a counterflow plate heat exchanger between the heat pump and the radiator system. Fixed flow temperature version.

Heat exchanger 2

Calculate heat output and COP for a system with a counterflow plate heat exchanger between the heat pump and the radiator system. Improved fixed heat output version.

Low loss header

Calculate heat output and COP for a system with a low loss header between the heat pump and the radiator system. Fixed heat output.

SCOP calculator

Calculate heat pump SCOP based on design flow temperature.

Dynamic heat pump simulator

Explore continuous vs intermittent heating, temperature set-backs and schedules.

tools's Issues

Hi, I have a student who is hoping to use your code as part of his masters project investigations. It could be very helpful for him. He has calculated heat losses for his buildings of interest but we are struggling to match these to the format you use in the dynamic simulator. We have overall heat losses for the building in W or U values for various surfaces in W/m2.K . It doesn't seem possible to find temperature dependant U values but your code is asking for heat losses in W/K at different temperatures. We are struggling to square this with the data that we have. Can you point us to documentation or help us solve the problem.
Many thanks
