Arctic Circle and Formpave develop heat storage solution

Arctic Circle and Formpave have teamed up to develop a way of storing waste heat underneath car parks.

Waste heat is stored under the car park.

Reclaiming heat from refrigeration is nothing new, but there are two main draw backs to conventional heat reclaim:

  1. In order to get the quantity and grade of heat required, it is often necessary to operate refrigeration systems less efficiently than their normal operation without heat reclaim.
  2. The demand for the heat is usually at its highest when the heat is available from refrigeration system is at its least (and vice versa).

The Arctic Circle integrated GSHP refrigeration system, combined with the Formpave Aquaflow system, addresses both of these issues. By storing the heat under the car park via a ground loop, the two main drawbacks have been turned into two major benefits:

  1. The Aquaflow system enhances the overall efficiency of the refrigeration system.
  2. The heat is available when it is required, and it qualifies for non-domestic RHI payments at 9.09 pence per kW.

According to Nick Franzen of Arctic Circle and Marc Youle-Grayling of Formpave, the carbon reductions, energy savings and the lifetime benefits of the system far outweigh the relative uplift in capital cost.
