Ice buildup at entrances during winter is a common problem, causing significant inconvenience. Air curtains are one effective solution. This article will detail air curtains, covering their principles, advantages, usage precautions, and selection criteria.
An air curtain uses an electric heater to warm air, then a high-speed fan creates a barrier of warm air, blocking drafts and cold air, preventing it from entering through the doorway. The basic principle is to indirectly prevent cold air entry by circulating a warm air barrier, thus providing a warm and comfortable environment.
Air curtains offer several advantages over traditional heating systems. First, they are an invisible physical barrier, not taking up doorway space and are easy to install. Second, air curtains have a long lifespan and relatively low maintenance costs. They also reduce the temperature difference between indoors and outdoors, minimizing cold air infiltration. Importantly, air curtains save energy, provide a comfortable indoor environment, and reduce the burden on heating systems.
However, using air curtains requires attention to several points. First, continuous power is needed, so a stable power supply is essential. Second, air curtains produce noise during operation; choose a model with an appropriate noise level for your environment. Regular cleaning and maintenance are also necessary to ensure proper operation and extend lifespan. The appropriate model and airflow speed should be selected based on the indoor-outdoor temperature difference and airflow at the doorway.
When choosing an air curtain, consider key factors. First, consider the doorway's dimensions to determine the required specifications and size. Second, select a model suitable for the environment, such as commercial or residential use. Also, consider the power and energy consumption, choosing an energy-efficient model that meets your needs.
