Appropriate Use of Ventilation and Air Purification to Reduce the Risk of COVID-19   The U.S. Centers for Disease Control website recently published an article warning of possible COVID-19 transmission via an air conditioning system operating in a Guangzhou, China restaurant. Epidemiologists researching this event describe an outbreak infecting dozens of restaurant patrons may have been prompted by AC ventilation. Although patrons were practicing social distancing by sitting at tables spread widely apart, the novel coronavirus still managed to sicken nearly all diners on a night the restaurant used air conditioning to cool the dining area. Authors of the article highly recommend...

What are Cooling Fans?  Almost everyone thinks of running a fan as a method for cooling down. However, not all fans can always do this job. In fact, basic fans are only able to bring about a feeling of coolness up to a certain temperature level, and they don't actually cool a room. To be able to truly cool an area, rather than just cool down the outside of people's bodies, it generally takes using an upgraded type of fan-based cooling. Large Fans for Cooling People These are basic fans, but they are industrially-sized and meant to move the air...

A number of factors weigh in the balance for successful cooling in the greenhouse, including sensitive plant species, humidity levels, and workplace safety for employees and visitors alike. To find out how many fans you need in your greenhouse, a few simple fan calculator tips are all that's needed. We'll show you how to do them below. How to Calculate CFM for Greenhouses The cooling rate for most industrial fans are  based on the CFM, or cubic feet per minute,  that measures how much air the fan pushes through in a measured time. Calculating CFM’s depend on the airspace in your greenhouse, so multiply the width...

If you are designing a commercial kitchen, the kitchen's ventilation system is important. This includes things like the exhaust fan, vent hood and air supply fans.
