Heating, Ventilation & Air Conditioning (HVAC)
HVAC Simulation is at the core of what we do here at our Singapore offices in BroadTech Engineering.
We are one of the industry’s leading CFD company in CFD consulting, HVAC concept planning, design and optimizing of HVAC design and development projects in Singapore.
Our Fluid dynamics simulation capabilities at BroadTech Engineering helps engineering companies to optimize HVAC designs and meet the ongoing challenge of developing simulation models that are energy efficient, sustainable and compliant with standards.
Meeting Green Building Design Goals with HVAC CFD Simulation
CFD (Computational Fluid dynamics) Engineering Simulation is accelerating technological innovation in building HVAC designs
With the ever-rising demands for green building consultants for sustainable architecture in recent the years, HVAC design engineers are developing more complex and diversified designs to reduce loads, maximise energy efficiency and tap renewable energy resources.
Computational Fluid analysis software simulations have proven to be an extremely powerful and effective engineering design tool, offering adaptable application in technically complex and demanding architectural environment HVAC projects.
At BroadTech Engineering, these CFD simulations and CFD analysis are heavily utilized by companies as a performance optimization and design validation tool at an early design development phase.
This is because CFD engineering simulation assists the implementation of innovative designs and energy-saving measures designed to decrease the overall building’s energy costs while maintaining or improving occupant thermal comfort in a building indoor environment.
Types of HVAC System we can Analyze
Our CFD simulation is able to analyze a number of complementary building HVAC system
Features & Benefits of HVAC CFD Simulation Analysis
Through HVAC CFD simulation, we are able to accurately reveal find out the impact of specific Air flow velocity and direction angle on the thermal temperature distributions were generated.
Benefits of HAVC simulation includes:
1. Accurate Full-Scale Simulation
With Engineering simulation, we are able to accurately simulate and optimize full-scale, three-dimensional virtual model of complex building indoor geometry design
For greater accuracy during the meshing of the 3D model, local mesh refinements can be added to areas that are of higher importance, such as areas near the air outlets and zones which are occupied by people
2. Enhance Energy Efficiency
Using the HVAC simulation result data from the initial fluid dynamics analysis, our consultants are able to visualize the airflow behavior inside the high-ceilinged hall and propose recommendations to improve airflow delivery.
Having an optimize air distribution of HVAC system to Reduce the energy consumption to a minimum and maximize energy savings
3. Ensure Occupant Indoor Thermal Comfort
Steady-state fluid dynamics simulations can be used to engineer and create an even temperature distribution across the entire indoor space. This helps to ensure that the thermal comfort of occupants in building indoor environment while being compliant with environmental requirements associated with Green building designs.
4. Optimize Air Delivery Distribution
HVAC simulation is able to analyze the flow performance of the existing and proposed HVAC air distribution system.
Base on simulation results obtain, we are able to Optimize optimal distribution of air supply outlets, air diffusers, ceiling flow bars throughout the different parts of buildings needed to ensure proper air delivery in large or High ceiling indoor spaces.
Having an even distribution of air helps to improve the temperature distribution at various levels of the building indoor space. This is achieved through the Fine-tuning of Parameters in the air distribution system such as Speed of airflow supply and angle of a direction of the air supply inlet.
5. Preservation of Air Thermal Stratification
We are able to engineer design solutions that avoid the disturbance of hot air thermal stratification region which is a key important energy-saving measure.
Because of this, Caution has to be taken when determining the placement and direction of Air supply inlets, such as flow bar diffusers to ensure that it does not induce significant disturbances to the hot stratified air layer
6. Optimize Air Return
Air Returns and Exhaust fan can be strategically installed in elevated areas of the indoor space to capture the rising movement of buoyant hot air from the occupied zones.
This air exhaust fan can also assist in the removal of any air contaminants or pollutants.
We Help Our Clients Gain Valuable Insights to Optimize and Improve Product Performance, Reliability, and Efficiency.
1. Improve Energy Efficiency of HVAC Systems
2. Ensure Occupant Thermal Comfort
3. Compliance with BCA GreenMark
Applications of HVAC Simulation
1. Identification of areas with high temperatures (around 25 ~ 31 degrees C).
This could imply an insufficient supply air flow to these zones or perhaps due to high heat loads from the equipment or high human traffic.
Base on this the air supply direction can be adjusted and velocity of air flow rate can be increased to improve air delivery distribution and lower the core volume temperature the accordingly.
Spot cooling can be used to neutralize out the high thermal heat emitted from a heat source, such as a group of occupants or server/ equipment so that disturbances would not be created at the upper hot stratified air layer.
2. Identification of Areas which are Overcooled
Base on this, the supply air flow velocity delivered to that zone could be reduced.
Predefined angles of direction in which the air is channeled can be adjusted accordingly
Examples of Building Environment which would benefit from an HVAC simulation
Such assembly hall usually consists of many levels and areas, such as the performance stage, catwalk, Audience seating area (which are typically divided into the first -floor level, Basement level, ground, Mezzanine-level and VIP private area) which are all interconnected by one central air continuum.
Implementing an HVAC CFD simulation analysis helps to ensure that the total airflow supplied by the hybrid cooling system cools the occupied zones but only temper the upper regions where maintenance catwalks are located.
Fluid flow simulations have become an instrumental tool in supporting our client’s HVAC design process through accurate simulation of thermal comfort conditions, fast design validation, and optimization, and reduce energy consumption for building HVAC systems.
The proven breadth and depth of advanced fluid dynamics modeling capabilities from BroadTech Engineering have enabled us to tackle a wide range of complex problems ranging from HVAC and smoke simulations, Air dispersion modeling, Air Quality Modelling and Fire Dynamics Simulation.
