Today huge amounts of money are invested in top of the line heat pumps, refrigeration and air conditioning systems, to save energy. But is this enough?
Sadly, it isn’t, and we repeatedly measure new (and old) equipment where 20‑30% energy is wasted. That is why we always recommend that ClimaCheck is installed from the start and used for the commissioning of your cooling system or heat pump, to ensure that it is optimised for your specific system, load and climate which is not the same as any other project. Thereafter, a structure for predictive maintenance should be established.
The energy graph shown below is a top of the line installation of two chillers and two heat pumps that is supplying a new data center with cooling. The heat is delivered to a local district heating network.
Yellow line – Outdoor temperature
Red bars – Energy consumption per 24 hours
Blue line – Energy consumption based on energy signature before optimisation (=predicted consumption)
Red line – Energy consumption based on energy signature after optimisation
Result – Savings of 2400 kWh/day (26% less energy consumption)
During the verification phase (see picture) another calibration was done and even more energy savings was possible. Today many companies focus is on state-of-the-art equipment and green energy which is good. But the possibility to save almost 30% energy is usually overlooked, many times due to challenges in the communication and lack in good way show the performance of the cooling systems and heat pumps.

Tougher times requires effective actions!
Based on thousands of analysed systems, we know that it is possible to save 10-30% in most air Conditioning, refrigeration, and heat pump (HVACR) system. Making it one of the lowest hanging fruits for energy savings in many buildings.
World Refrigeration Day 2022 – 26th June
ClimaCheck have optimised thousands of systems during the years, and it is from all these systems we know that it usually is possible to save 10-30%, by using information form performance analysis to optimise the system.
ClimaCheck wish you an amasing midsummer!
On Friday it is midsummer in Sweden and our office will be closed. We will ...
