UVC-basedĪir curtains use UVC light to kill airborne viruses before recirculating clean air back into an area.Īir curtains deter flying pests from entering workplaces. In busy warehouses, air curtains are an ideal replacement for grimy, dirty strip curtains that impair visibility, which can be particularly dangerous in forklift zones. The downward stream of air helps keep the floor free of slipping Perhaps one of the most important and overlooked benefits of an air curtain is its ability to improve the level of safety on doors where it operates. That can easily and negatively affect productivity, well-being, Whether a large dock door or a customer front door, the infiltration of unconditioned outside air can make life miserable for those close to the door. Try our Cost Savings Calculator to see how much you could save Increased Comfort for Customers and Employees Ultimately, this can lead to considerable cost savings. The HVAC system will not have to work as hard. Air curtains prevent the inside air from escaping and the outside air from entering. WhileĪn open door may signal a booming business, it also lets the inside/conditioned air leak out and the outside air seep in. Air curtains help prevent this while lessening the strain on the unit's cooling refrigeration.įrom Alaska to Florida, air curtains effectively separate environments and complement your building's primary HVAC system, helping drive down costs by lessening the need for the system to constantly be running. In Cold Storage applications, the mixing of refrigerated air with ambient air can create safety hazards such as Rooms, air curtains create an invisible barrier to prevent the mixing of one environment with another. Whether you're blocking frigid winter winds from entering through a customer entrance door or separating two interior Why Use an Air Curtain? Temperature + Environmental SeparationĪ core function of an air curtain is its ability to separate temperatures/separate environments. The Physics Behind Air Curtains EffectivenessĬomputational Fluid Dynamics (CFD) is one of the branches of fluid mechanics that uses numerical methods and algorithms, rather than model experiments, to solve and analyze problems that involve fluid flows.Ĭomputers are used to perform the millions of calculations required to simulate the interaction of liquids and gases with surfaces defined by boundary conditions. This air should already be free of insects because they will not fit through the intake screen. In this situation, it doesn't matter if some of the outside air is blown inside after it splits at the floor. Mounted on the outside of the doorway as long as the discharge is adjusted so the air is blowing back toward the outside. If the unit is to be used for insect control, the air curtain can be If the unit is on the other side of the opening, some of the cold air that needs to be kept out would be blown inside, defeating the purpose. Is leaked to the outside and some is blown back inside. Is used for climate control, it should be placed on the opposite side of the doorway from that of the air that is to be kept out.įor example, if it is winter and you are trying to keep cold outside air from entering a building, the air curtain would be placed on the inside so that it is blowing warm air. When the discharged air reaches the floor it splits, forcing some air outward and some inward. Usually the ideal discharge angle for maximum wind-stopping capability is around fifteen degrees.
