Lowering Humidity Levels in the Workplace

Summer is still here and with it comes heat and humidity. The dangers of heat exposure are already well known and, although humidity may not present the same risks for your employees, it can still make for a very uncomfortable workplace.

And if you or your employees are not comfortable, productivity levels will go down. UK laws already suggest a minimum temperature in the workplace and, even though there no set requirements when it comes to humidity, most people understand that its levels need to be managed for a stress-free workplace, be it in a warehouse or an office.

What is Humidity?

When water heats up and evaporates to the surrounding environment, the subsequent water in the air will make it humid. Relative humidity is a term that refers to the ratio between the levels of water in the air and the maximum amount of water the air can hold at the current temperature.

Benefits of Reducing Humidity

Anything between 40% and 70% when it comes to relative humidity will not impact your employees’ thermal comfort. However, values outside of these can. It’s imperative to have measures in place that can decrease humidity in the workplace, then, which often take the form of air conditioning systems that can provide relief against excess moisture in the air.

The benefits that come from this decrease are invaluable. High levels of humidity, such as more than 80%, mean a lot of water vapour in the air, which in turn means that sweat cannot properly evaporate – and sweating is the mechanism by which bodies regulate temperature and reduce heat.

Why Your AC Helps

Air conditioning units are effective at controlling the levels of humidity in the air if they’re the right size for your workplace. Small air conditioners are more adequate for small spaces, as they can perform work to a more satisfactory level – otherwise the AC will have to strain itself, which can lead to overheating and malfunctioning.

The air conditioner in your workplace works by removing the water vapour in the air and replacing it with cool air – more specifically, when moisture comes in contact with the cold evaporator coil of the AC unit, it becomes condensed, making the space less humid. The moisture that gathered inside the system is sent outside, away from your workplace.

People feel uncomfortable when the levels of humidity rise, because we tend to cool off by sweating, which is made more difficult by the excess water vapour in the air. By using your air conditioning system to reduce this humidity, you can increase the comfort and well-being of your employees – as well as your own.

At Heritage Heating and Cooling we strive to provide you with the best AC units in the market, manufactured with the latest technology, so that your workplace can benefit from comfortable humidity levels!
