Heat transfer fluids for heat pumps

Heat pump is an innovative thermal equipment that becomes used wider and wider. The heat transfer fluid circulates in probes, which are placed either in the soil or in a natural body of water.

Probes of a heat pump are made of plastic. However, the circuit also includes a metal heat exchanger.

When selecting a heat transfer fluid, you need to address two fundamental issues:

  • What should be the basis of heat transfer fluids (propylene glycol or ethylene glycol);
  • Whether corrosion inhibitors to protect the metal are needed.

In our view, if we consider the probability of leakage of the heat transfer fluid into the environment, the first question is answered in favour of propylene glycol.

When addressing the second question, consider the type of metal of the heat exchanger, as well as servicing (repairs) in the future.
