It is the sensors of the ClimaCheck to a system: applications, for example, troubleshooting HVAC&R systems installed by contestants acknowledged that cooling has a cost, two pressure sensors, seven temperature to minimise energy consumption in the Swedish skills competition was but how much should that cost be? sensors and one sensor to measure the costs, preventative maintenance to validated by ClimaCheck.

The sensors are basic and do alert possible imminent breakdowns, of new synthetic refrigerants have also Who is accountable for efficiency? not require the plant to be stopped. Once validation of plant performance after used ClimaCheck to validate cooling The design engineer is required to meet the sensors are connected to the ‘black commissioning and quality assurance performance at different conditions. the specification and the contractor to attain the required temperature. The plant owner is only familiar with temperature and needs to pay the bills. No party is given the responsibility for validating plant performance. The fundamental issue in the HVAC&R industry is that system efficiency is no‑‑one’s responsibility; but not only that, until now it was nearly impossible to measure. It is acknowledged that cooling has a cost, but how much should that cost be? The actual performance of a plant differs from the technical specifications of the different components, and is influenced by many variable operating parameters. “The ClimaCheck can be considered as the electrocardiogram (ECG) of HVAC&R installations,” says Berglöf. “The process starts with field know what’s happening when it’s happening INCORPORATING COLD CHAIN e-newsletter go to www.coldlinkafrica.co.za to subscribe 32 www.coldlinkafrica.co.za COLD LINK AFRICA • July | August 2016
