HVAC & THERMAL COMFORT
Meeting ASHRAE and ISO Standards for Thermal Comfort Compliance in Building Design with ANSYS-CFX and IES: Flowpak’s Solutions
ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers) and ISO (International Organization for Standardization) have thermal comfort standards in buildings. These standards provide guidelines for the indoor temperature, relative humidity, and air movement that should be maintained in order to ensure that occupants are comfortable.
At Flowpak, we use advanced numerical simulation tools such as ANSYS-CFX and IES (Integrated Environmental Solutions) to assist architects, designers, and contractors in Qatar and abroad in achieving the thermal comfort requirements set by these standards.
By utilising these tools, we can analyse and optimise the HVAC systems in a building to ensure that they are meeting the thermal comfort requirements set by ASHRAE and ISO. We can evaluate the effectiveness of different design options and identify potential issues before the building is constructed, which allows for more efficient and cost-effective solutions.
Flowpak’s CFD Analysis Solutions for Optimizing HVAC Systems at the Children’s Mall in Katara Cultural Center
The Children’s Mall in Katara Qatar is a unique and contemporary shopping centre designed for children.
The mall offers children a wide range of products and services and features play areas and interactive exhibits.
The mall was built within the Katara Cultural Center.
The mall’s design, which is inspired by a Gift box, was challenging to integrate with an efficient VAC system.
To overcome this challenge, the mall’s developer, blue Qatar, hired Flowpak to perform CFD analysis to assess the thermal comfort in the building and ensure the VAC system’s ability to maintain the required temperature of 24 degrees Celsius.
Flowpak’s CFD Analysis Solutions for Optimal Conditions during Handball, Badminton, and Ice Rink Events at Ali Bin Hamad Al-Attiya Arena
The Ali Bin Hamad Al-Attiya Arena is a multi-purpose indoor facility located in Al-Daayen, Qatar. Constructed in 2012, it boasts a capacity of 6,000 individuals and was purpose-built to host the Handball World Cup in 2015.
The arena primarily serves as a venue for handball, badminton and Ice Rink events.
In order to ensure optimal playing conditions for badminton, the maximum air velocity within the arena should not exceed 4.8 m/s (10.8 mph) to prevent disturbance of the shuttlecock.
This is considered the standard wind speed limit for badminton matches.
To validate this, James and Cubit Consultant have commissioned Flowpak to conduct a CFD simulation of the arena’s thermal comfort and verify that the VAC system does not generate velocities above 4.8 m/s at the badminton playing area, in addition to checking the temperature profile above the ice rink to maintain the consistency of the ice.
Flowpak experts performed CFD simulations for different scenarios to select the optimum VAC system that can perform under different scenarios and thermal loads for different events.
Seeroo fi al Ardh Pavilion: A Fusion of Creativity and Efficiency with FlowPak’s CFD Analysis for HVAC System Design
The Seeroo fi al ardh pavilion in Qatar Foundation is the final artwork of Maqbool Fida Husain; it is a 46m diameter circular carousel with a total building height of 12m; it has a glazed façade consisting mainly of 6 single sliding curved glazed modules.
The building envelope was designed to provide visitors with a unique and immersive experience while being energy-efficient.
The installation represents humanity’s progress on land, in the air, and sea and their inclination to utilize the surrounding resources to achieve their goals.
STRABAG / ZÜBLIN INTERNATIONAL selected Flowpak to perform CFD simulation via ANSYS-CFX to select the best optimum VAC system for the building’s HVAC system to provide thermal comfort for the visitors.
