Designing air conditioning projects for buildings is generally an assiduous job, adding calculations for checking compliance with regulations makes it even more complicated and it is due to these considerations that LG has invested to ease designer’s tasks.
European Standard EN 378 limits the gas concentration (kg/m³) for buildings that receive people (for work, health, schools and hospitality). The regulation became effective from 01 Oct 2000 – and is directly applicable in law in all EC countries. It states that all precautionary measures practicable shall be taken to prevent and minimise leakages of refrigerants from refrigeration and air-conditioning systems.
After a detailed conception of an air conditioning project for a building is completed, the designer’s job is not yet done; further calculations need to be conducted in order to establish conformity to several European laws.
LATSCAD calculates and checks compliance for EN378
The more complicated the project, the harder it gets to wrap-it-up. Imagining a multi-storey building, after calculating loads / selecting air conditioning solution / designing systems, still conducting EN378 calculation for each system is needed. LATSCAD has recently integrated a function that calculates and checks compliance for EN378 automatically at system check simulation.
With this function, designing time has significantly been reduced – for example the above case study, a hotel building of 7 floors with a 875 m² and 8 variable refrigerant systems has been designed in 6 hours, out of which 36 seconds represented the simulation time. After simulation, a designer easily observes which system is not EN378 conform by the red signalled numbers and unchecked mark.
The provided comfort by confidence
LG Electronics Air Conditioning and Energy Solutions Division is driven to provide a total package to its partners, amongst which designers represent a key entity. For designers, LG’s commitment is extended into providing EN378 conformity simulations dedicated to its systems regardless of application. Considering LATSCAD’s evolution, in only 2 years designing LG air conditioning systems has become easier and more accurate than ever securing: precise system design, AUTOCAD view, summarizing excel report and conformity simulations.
