Tests conducted within the field of Climate Engineering encompass the set of measurements necessary to establish combustion and energy consumption evaluations, in the aim of determining the overall performance of various types of systems (heat pumps, heating devices). These resources are also deployed in testing the safety of using an array of product types, like smoke exhaust ducts, ethanol combustion chambers and charcoal-fired barbecues.
Proposed services
Among the services we make available in this field, please note the following :
- Analysis of combustion products (CO, CO2, O2, dusts, etc.),
- Measurement of thermal comfort in a climate-controlled chamber,
- Measurement of temperatures (gases, surfaces, radiated temperatures, etc.),
- Measurement of fuel consumption,
- Establishment of a thermal assessment, thermal efficiency or heat pump coefficient of performance,
- Performance tests on carbon monoxide detectors (DAACO),
- Performance tests on oil-filled radiators, independent heating, ethanol combustion chambers,
- Performance tests on metal smoke exhaust ducts,
- Performance tests on charcoal-fired barbecues.
