Delivering comfort in a large venue is a staggering part its energy expense. As an HVAC innovator, Withair® brings advanced technologies to the challenge like renewable heat pump technology, next generation inverter compressors, variable-speed drives, building automation systems and IoT sophistication to help monitor, control and manage the function and performance of your HVAC investment. These solutions also boast compact envelopes to reduce installation space. Quiet operation helps keep noise inside where it belongs and helps you meet stringent suburban noise requirements.
A great spectator experience starts with a great venue...and that venue must be comfortable. That comfort, however, should be delivered so effectively, so subtly and so efficiently as to go unnoticed. That’s where Withair® can help. We understand that the patron or fan’s focus should be on the artistry or the competition—or when in the gym, on the next rep or goal. While controlling comfort in sports and entertainment venues is a challenge, on the scale of the facilities themselves, our rich experience and innovation is equal to the task.
Meet Unique Requirements
For sports and entertainment venues, large quantities of ventilation typically are required to meet occupancy demands. In addition, there are significant latent loads from the occupants. These factors normally require air handling systems to be designed with both humidification and dehumidification. In addition, the systems are often used intermittently and are required to bring the house to setpoints quickly after the arena fills up and lights are turned on. Because of the large ventilation loads, there is significant opportunity to save energy through air side heat recovery from exhaust air streams. This is typically done through run-around coils, air heat exchangers, and heat pipes.
Some sports arenas save energy by using green HVAC technologies. they employs a geothermal HVAC system to get cooling, heating and recover waste heat. The heat is stored in 200-foot-deep wells and retrieved during the winter to keep fans toasty.
The Stadium requires a large cooling power, huge structures rely on centralized air conditioning systems. Usually, several units are placed in one location, known as the central cooling station.
To spare fans from the noise this equipment makes, central cooling stations are usually placed in the basement or on the roof of stadiums. Each floor of the stadium holds several air handling units, which distribute the cooled air through ducts. Rather than pump the same temperature and amount of air throughout the entire building, each area is zoned for its specific needs.
The large size and varied uses and occupancies of sports arenas make for unique air distribution challenges.
Significant swings in outside air requirements to combat quickly rising carbon dioxide levels requires a demand-control ventilation system. Many arenas overcome this challenge with a dedicated outdoor-air system (DOAS). These systems work independently of the cooling and heating units to channel fresh outside air into the building. Not only can a DOAS reduce the amount of fan energy needed, but it can also improve indoor air quality and serve as a dehumidifier. Dehumidification is essential to maintaining ice rinks.
What type of refrigeration system does it take to freeze the 12,000 to 15,000 gallons of water needed to make a professional ice rink? A complex network of chillers and steel pipes embedded in concrete or refrigerant-cooled brinewater underneath the ice to keep it frozen. Ice temperature controls are used to meet the needs of the various sports. Withair® have widely product lines to meet these requirements.
