3. About ClimaCheck
ClimaCheck is performance and efficiency monitoring platform for cooling systems.
Invented in 1986 in Sweden it uses a scientific process to identify energy inefficiencies and issues affecting reliability and maintenance costs.
The technology was developed and refined and due to growing international demand, the company ClimaCheck was formed in 2004 to service markets worldwide.
The process is totally non-invasive and uses raw temperature, pressure and energy data from any vapour compression system (cooling or heat pump) to measure the performance and efficiency.
At its core, ClimaCheck provides plant owners and their operators high level key performance indicators and accountability for efficiency and reliability.
Thousands of customers around the world trust ClimaCheck - from a mission-critical data centres in North America to a cooling system for a hotel in China of 300MW.

8. The law of the conservation of energy:
How does it work?
The law of the conservation of energy:
“Energy cannot be destroyed”
The law of the conservation of energy: “EnergyThe law of conservation of energy, a fundamental concept of physics, states that the total amount of energy remains constant in an isolated system. It implies that energy can neither be created nor destroyed, but can be change from one form to another”.

ClimaCheck onsite - field measurements minutes to connect
ClimaCheck online – continuous monitoring
- Early warning – energy reporting
All starts with measuring - To measure is to know!
The ClimaCheck performance analyser logger is connected to equipment for measuring all relevant parameters.
Collected data is then analysed either with a PC software for field measurements or via online with server for fixed monitoring.
Information presented is very easy to survey and provides the keys for optimising the performance.
The result is significant savings in time, in equipment and in energy.
The Monitoring system is fixed for online analyses of equipment installed at end users – the equipment owners.
Commissioning engineers, consultants and service contractors use the portable field measurement system in their work. Usually, the ClimaCheck software is installed in a PC for direct analyses of equipment.
