Distribution and Warehousing
With very high ceilings and vast storage areas that are ever changing due to stock and materials movement, distribution and warehouse centers face ongoing temperature control battles during the summer months (with or without air conditioning).
The colder months provide yet another challenge: how to achieve even heat distribution throughout all levels of the structure.
And during any season, adequate ventilation is yet another often troubling issue.
Airvolution™ HVLS warehouse fans from MacroAir Technologies can solve all these problems, efficiently and cost-effectively.
Summer
When it’s hot in facilities without A/C, the slowly moving air created by Airvolution warehouse fans breaks up the moisture-saturated boundary layer surrounding the body, accelerating evaporation to produce a cooling effect of as much as 8 degrees. When used in conjunction with air conditioning or evaporative cooling systems, Airvolution warehouse fans can efficiently circulate cooled air throughout the structure and have an increased cooling effect.
Winter
During the cold months the basic problem is temperature stratification. As heated air rises, it gets caught at the ceiling. This hot air can typically yield well in excess of a 15° F differential from that found on the floor. Airvolution warehouse fans run in reverse (a standard feature from MacroAir) circulates this trapped heat, continually forcing it down throughout the facility, providing even distribution of heat from floor to ceiling–especially important when employees are working at different levels. Our studies found that Airvolution warehouse fans can reduce the difference in these temperatures to within 1-3 degrees. In a situation where the difference was 15 degrees (without a fan), the rise in temperature (with a warehouse fan) on the floor would be 5-7 degrees. Furthermore, because the warehouse fans would be running in reverse for the winter, there’s never a chilling breeze, air movement is almost imperceptible. The warm air moves slowly off the walls toward the center of the hanging warehouse fan.
Ventilation
Airvolution warehouse fans also provide superior ventilation capabilities. They continuously mix incoming fresh air with stale air, thus minimizing the total amount of ventilation required to achieve adequate air quality. No other warehouse fan, system, or ventilation technology does this better.
Cold room
Heat in cold rooms whether the temperature is low or medium, stratifies just as it does in open un-conditioned areas. MacroAir warehouse fans can circulate the cooled air and balance the temperatures from floor to ceiling. In regions of the country where average energy rates are calculated and applied to the next period based on peak demand hours the cost savings can be significant.
Here are just a few of the benefits you can expect when you install HVLS fans in your warehouse:
- When used as a stand-alone system for heat relief, they can yield an effective cooling of up to 8° F, within the warehouse fan’s coverage area (up to 20,000 square feet for a 24 foot fan).
- When used in conjunction with an air conditioning system, the slow and steady air flow can reduce or eliminate the need for costly duct work and increase the efficiency of the system with increased circulation.
- Effective for shipping docks, and other areas with opening doors and bays. The horizontal floor jet continues outward into these openings providing extended relief.
- During heating seasons, Airvolution technology de-stratifies uneven temperatures that occur at each level throughout the facility – forcing unused heated air from the ceiling down to floor where it can have a positive effect on employees. This heat differential can be in excess of 15° F from ceiling to floor, enabling significant cost savings when thermostat levels are reduced.
- One Airvolution HVLS fan consumes about the same electricity as one high-speed alley fan while moving over 12 times the amount the air.
- One Airvolution warehouse fan costs about a nickel an hour to operate.
- Better ventilation reduces spoilage due to pent-up moisture pockets, humidity and heat.
- Peak hour cold room de stratification, can reduce the energy rate for the whole month.
- Quiet and non-disruptive operation.
