Efficient refrigeration

Tackle one of the most underestimated sources.

Refrigeration — fermentation control, cold stabilisation and storage — is one of the biggest and most underestimated sources, especially in warm climates. Cooling efficiency has two fronts: the energy consumed and refrigerant-gas leaks.

Right-sizing, insulating tanks and rooms, maintaining equipment and choosing low-warming-potential refrigerants reduces both. It is often a cellar’s single biggest efficiency opportunity.

Energy

Since cooling is a large share of cellar energy, making it efficient reduces total consumption.

How it works

Reducing cooling load and losses — through insulation, maintenance and good refrigerants — cuts energy and avoids direct leak emissions.

How to implement

  1. 1Insulate tanks and cold rooms.
  2. 2Right-size and maintain the cooling equipment.
  3. 3Monitor and repair refrigerant leaks.
  4. 4Log consumption and leaks for the footprint.

Frequently asked

Do refrigerant leaks matter much?

Yes — many refrigerants have a warming potential hundreds to thousands of times that of CO₂, so small leaks weigh heavily.

How to reduce the cooling load?

Insulation, managing cellar ambient temperature, night-cooling recovery and good maintenance reduce the energy needed.
