CHALLENGE

Too much electricity is wasted by refrigeration and air conditioning systems.

Did you know that 15–20 percent of the global electricity consumption is used for refrigeration and air conditioning? In hot climate zones it can be as much as 50 percent. Often one third of the electricity is wasted due to inefficient operation. Refrigeration processes are used throughout society for cooling foods and processes, air conditioning, heat pumps and dehumidifiers. For the supermarket owner or the building operator, the electricity cost for cooling is often a hidden cost within the entire energy bill, but often represents 40–60 percent. The majority of cooling systems are not working as efficiently as they should, with higher energy costs, increased risk for down time or failure, and in the end, increased carbon dioxide emissions as a result. Generally, there is a huge misconception that if a system is cooling effectively it must be efficient!

To reduce energy consumption, a clear picture of how the system is working is a must. Good analytical tools and methods are the basis for optimising the efficiency and minimising downtime. It has previously been difficult to cost effectively measure the performance of refrigeration systems in operation. Not anymore!

PIONEERS IN ENERGY OPTIMISATION

ClimaCheck was founded on a strong belief that the energy consumption in the world has to be significantly reduced to minimise the environ­mental impact it has on the world. ClimaCheck is an award winning company helping customers to increase efficiency, reliability and lifetime of refrigeration, air conditioning and heat pump systems.

Global brands such as Carrier, Johnson Controls, Emerson, IKEA, Sobeys, Bureau Veri­tas, Schneider Electric and Tesco have decrea­sed their energy consumption with ClimaCheck. Many leading service and maintenance con­tractors, and consultants have enrolled in the ClimaCheck Partner Program and together we are changing the way the performance of coo­ling and heat pump systems is measured, analy­sed and optimised.

The ClimaCheck Performance Analyser allows you as a property owner, contractor, consultant or manufacturer to scientifically analyse and evaluate practically every type of cooling or heat pump system. ClimaCheck documents baseline performance and provides precise information on all potential areas for improvement and savings.

CLIMACHECK ONSITE

For quick system measurements and adjustments during Service or Performance Inspections, use our ClimaCheck Portable Field Case version. Connect sensors in less than 30 minutes and you will have a complete analysis on how well heat pumps, refrigeration or air conditioning systems are running.

CLIMACHECK ONLINE

A ClimaCheck Fixed Installation provides continuous monitoring of energy consumption, compressor and system performance. The system automatically sends an alert (email or SMS) if performance deteriorates, and you can at any time log in online to the cloud based portal from any computer or mobile device. You will have access to real time information via a System Efficiency Index (SEI) Dashboard, including Energy Signatures and Reports. Compressor and heat exchanger performance, as well as potential refrigerant leaks and the equipment energy profile, are monitored 24/7.

REDUCING ENERGY CONSUMPTION AND ENVIRONMENTAL IMPACT

ClimaCheck documents baseline performan­ce and provides information on potential sys­tem weaknesses. You can directly compare the cost of energy optimisation against calculated savings once the performance base line is do­cumented. On project completion you have a re­cord of improvements, ensuring your investment is paying back. Studies and practical experience shows that ClimaCheck can reduce energy consumption by as much as one third. Where a fifth of world energy consumption is used for cooling, these energy reductions directly reduce global carbon dioxide emissions.

The ClimaCheck Performance Analyser is used to document all types of vapour compression systems such as refri­geration, air conditioning and heat pump systems:

• Product and System Development – leading manufacturers use ClimaCheck solutions for development and product quality control. ClimaCheck supplies test rig analysing systems to manufacturers.
• Commissioning/Recommissioning/Warranty Inspections – after installation of new equipment or at the end of the warranty period, ClimaCheck confirms if the plant is running at the rated capacity and energy efficiency.
• Performance Inspections – EU Directives require performance inspections of all air conditioning units over 12 kW. ClimaCheck provides accurate and unbiased performance validation more cost effective than any other system.
• Energy Optimisation – ClimaCheck provides high quality decision support prior to energy efficiency measures in cooling systems and heat pumps. Internet access allows experts to study and diagnose operation effectively from anywhere in the world.
• Troubleshooting – ClimaCheck makes troubleshooting and fault correction a much simpler process, minimising engineers’ time and energy costs, whilst extending plant life.
• Preventive Service & Maintenance – ClimaCheck is used for temporary or continuous monitoring of cooling and heating systems. Predefined performance reports and alarm levels ensure the equipment is working efficiently. In the EU, the number of annual leak detection visits are reduced by 50 percent when ClimaCheck is used as an indirect leak detection system.

More accurate and reliable performance measurement

The method is scientifically based on the thermodynamic evaluation of measured data. The ClimaCheck solution is connected to ten measuring points for a basic circuit – data are collected and used for calculations and analysis. The ClimaCheck method provides unique information and results that no other system can, including:

• Cooling and Heating Capacity (kW).
• Coefficient of Performance COP/ EER.
• Compressor Isentropic Efficiency.
• Condenser Efficiency.
• Evaporator Efficiency.
• Electrical Power Input.
• Air/Water Flow Rates.
• Superheat/Sub-cooling values.
• Indication of excess or inadequate refrigerant charge.

Benchmark, validate and optimise

You have a scientific tool with which to document the performance of cooling processes that is independent of input from the manufacturer, supplier or service provider of the equipment and is therefore completely unbiased. Thus, the performance can not only be measured, but also validated and benchmarked against design and manufacturer’s data. The

ClimaCheck solution provides objective documentation for the total performance of the equipment and also shows the detailed functionality of each component. This provides you with a sound basis for adjusting and optimising the equipment for reduced energy consumption and increased operational reliability. System efficiency can be monitored 24/7 and energy reports distributed via e-mail at desired intervals.
