The refrigeration process is continually analysed with ClimaCheck Software within your PC or via the ClimaCheck Web Server. The ClimaCheck Internal Method accurately calculates refrigeration system performance using temperature, pressure and power measurements and was first patented in 1986.
ClimaCheck PA-PRO in the Field...
Mike Creamer, founder of Business Edge Ltd, has been using ClimaCheck for some years now. Mike is well-known throughout the AC&R Industry for his technical ability and has written over 140 Technical Articles, including the MasterClass-Air Conditioning Technology Series, that stills runs today within the ACR News Journal after 13 years! (Note-You can find the Series here on our Website in the MasterClass documents)
The consultancy team's services are frequently required to resolve site and equipment related defects and, as a result of our experience in manufacturing, design, electronic control systems, refrigerants, software engineering and so on, we are able to detect and rectify problems on almost any type of system.
Whilst Mike and his team might be accomplished AC&R Doctors, a Doctor requires the best tools available for his work.
ClimaCheck Software and ClimaCheck Performance Analyser Pro
The ClimaCheck portable or fixed installation Logger and Software allows you to document system performance via the Internal Method for virtually every type of compressor-driven cooling, air conditioning, refrigeration and heat pump system. ClimaCheck is often used over the entire life of the A/C or refrigeration system. For example:
• By the manufacturer during the initial Product and System R&D Phase
• Initial Site Commissioning
• Regular Site Inspections via Service & Maintenance Visits
• Trouble-Shooting / Fault-Finding
• Mandatory Performance Inspections & Energy Optimisation
EU-Regulation requires that all air-conditioning systems above 12 kW are “Performance Inspected”. Documented measurement using ClimaCheck provides a sound, consistent and accurate basis for these inspections, whilst also allowing fault and loss of refrigerant detection and plant optimisation, including:
• Expansion Valve adjustments
• Refrigerant charge checking and correction
• Calculation and adjustment of air and water flow rates, temperatures, pressures and more
This technique has been verified by manufacturers, universities, testing institutes and Refrigeration Technicians & Engineers across many thousands of field trials and installed application measurements. During 2006, the Royal Institute of Technology in Stockholm conducted an extensive Survey of 164 Performance Inspections using the ClimaCheck Performance Analyser as the basis for deriving accurate and consistent refrigeration system performance data.
Where necessary, ClimaCheck enables our technicians to see literally every key and relevant parameter during system start-up, running and shut-down cycles. This enables us to view the precise behaviour of the system and its control behaviour. We are then able to diagnose system defects, which we then immediately set about rectifying.
We can adjust refrigerant charge, expansion valve superheat, control parameters of Electronic Expansion Valves, Head Pressure-Low Ambient Control settings, control deadbands and more.
Mike states "ClimaCheck enables me to "see" what's happening throughout the A/C or Refrigeration System. If you can see it, you can fix it!
Moreover, since ClimaCheck shows every parameter in graphical, tabular and system schematic formats, it is an ideal on-the-job training tool for the young developing AC&R Engineer. I believe this technology will transform the lives of our future Engineers, making their work far more valued, effective and enjoyable. Moreover, they will do a better job more rapidly than before whilst issuing the End-User with a meaningful and accurate Report.
Most importantly, they will be able to optimise plant efficiency, increase its reliability, reduce energy costs for the End User and reduce CO2 emmissions in one profitable move!"
ClimaCheck can establish the performance of any type of air conditioning or refrigeration system, including Cooling (or Heat Pump) Capacity, Power Input, COP, Compressor Isentropic Efficiency, Superheat, Sub-Cooling, Refrigerant Charge Status and so on, without the need to establish airflow / water flow rates, air / water entering / leaving conditions!
Indeed, since ClimaCheck can record the entering and leaving water temperatures at both an evaporator and condenser, the cooling capacity and total heat rejection values can then be used to calculate the water / air flow rates!.
ClimaCheck is available as a Portable Performance Analyser
or as a Permanently Installed Performance Analyser.
Portable Performance Analyser - can be connected to most systems within 20 30 minutes and the results displayed in Tabular Worksheet, Graphical or System Schematic Formats. Results can be read at 1sec, 5sec, 30sec or 60sec intervals.
Permanently Installed Performance Analyser - a DIN-Rail Mounted Module, including Power Meter and Current Transformers, thus enabling the Plant to be consulted locally via a Notebook PC or via a direct Broadband Connection for local / remote communications. In addition, the ClimaCheck system can be supplied with a MODEM, SIM Card and Telephone Account to enable remote communications to be managed on a wireless basis. Finally, ClimaCheck can be programmed to issue specific text warning messages to a mobile phone. One major supermarket has started using this ClimaCheck format to monitor all their new CO2 and CO2/R134a Refrigeration Pack Installations, each of different configuration, for comparison purposes.
The product has been evaluated and Certified by the Swedish Institute of Technology and was also a Highly Commended Product at the Industry Cooling Awards under the Field Service Innovation Category. ClimaCheck also won the Refrigeration Product of the Year Category at the ACR News Awards in February 2009.
Business Edge have used ClimaCheck for over 3 years now on a number of special projects, which have centred around trouble-shooting, arbitration, legal cases, etc., and have also used succesfully it for Servicing & Commissioning Visits on DX, VRV and Water Chiller installations up to 1500kW Capacity.
ClimaCheck Systems have been purchased by Tesco (for CO2 Trans-Critical Systems Development), Eaton Williams (1 for Service Dept + 1 for Product R&D), Excalibur (Chiller Energy Analysis), Elyo Services (Service & Maintenance Division), Powrmatic (Heat Pump Development) and many others.

New “coil” power meter
ClimaCheck launches Power meter with Rogowski coils that offer a unique flexibility as the coils can be mounted where access with a conventional current clamp may be impossible.
New Low pressure sensors
ClimaCheck introduce a low pressure sensor with a range adapted to R-123 and other low pressure applications. The range of these sensors are -0.7 to 5 Bar(g). Obviously this sensor has the ClimaCheck special design with a very reliable Teflon O-ring instead of rubber seals or copper washers (which are challenging to mount without risk of leakage).
ClimaCheck's unique performance analysis method has now been further enhanced with sub efficiencies deviation analysis.
System Efficiency Index
Sub efficiencies highlight deviations from ideal performance of each component in the system and can trigger alarms long before any decrease of performance can be noted by the user.
