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.
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.
To measure is to know
