Engineers are more interested in the product’s reliability, quality, dimensional details, materials supply, or manufacturing processes. In a typical product development process, engineers and product designers work together, but they often have different goals for their projects. HVAC Systems 5 Tips for HVAC System Design 1. The alternative solutions that can help to reduce noise pollution are silent ventilation equipment, silencers and insulation materials for HVAC protection, or implementing a noise optimization analysis. The most common sources of noise pollution in the work environment are related to fans, variable air volume systems, grilles and diffusers, chillers, compressors, pumps, standby generators, boilers, and cooling towers. Noise reduction is another important factor in creating a pleasant living and working environment. The study of aerodynamic or thermodynamic forces is very useful in identifying the optimal equipment position for a specific location. HVAC product designers can drastically enhance the characteristics of equipment by analyzing simulation charts for factors like temperature, pressure, and velocity distribution. HVAC Simulation Saving Time and Money with Simulationīy implementing simulation activities, the HVAC system design process is radically simplified:ĭesign > Simulation (CAE) > Design Changesįor HVAC systems, designers and engineers will typically perform fluid dynamics ( CFD) and thermal simulations to improve the air conditioning circulation and comfort factors for different indoor or outdoor scenarios. The process of prototyping and testing can take weeks, and sometimes HVAC designers or architects don’t have this time available in the design schedule. The unpredictable costs associated with the supply and the need for testing laboratory activities also need to be considered from the outset. Otherwise, the testing process can involve hundreds of prototype changes and iterations, leading to unpredictable scheduling and costs that are impossible to predict.
There are several critical issues that arise in relation to the quality, time, and costs related to the prototyping cycle.įinding an acceptable solution in a reasonable time-and with reasonable costs-can only be achieved by working with very experienced HVAC system design teams. HVAC Design Challenges in HVAC System Design ProcessesĪ classic HVAC system design process is based on four elementary steps:ĭesign > Physical Prototyping > Testing > Design Change Cloud Heating, Ventilation, and Air Conditioning (HVAC)Įngineering simulation is being increasingly adopted in the design process as a strategy to address these challenges and to ensure the energy efficiency and optimal performance of HVAC equipment.
