Air Conditioning In Humid Weather

Feb 6

How high humidity affects us

Our bodies sweat to regulate our temperature. When we sweat, the body releases water and salt, and when this water evaporates, it takes some of the body heat with it.
That is why a breeze cools you down. It is not the air temperature but the evaporation process that happens on your skin.
When relative humidity is high, sweat evaporates slowly because the air is already saturated with moisture and cannot absorb any more. So the sweat does not evaporate as quickly and just sits on your skin with nowhere to go.

That’s why you feel so hot on humid days, even if the temperature is under 30 degrees.
Your body has a more challenging time regulating its temperature, making it more susceptible to heatstroke. So take extra precautions when you go outside in the heat and humidity.

Many of us stay indoors on sweltering days, but sometimes there’s no escaping the humidity, even in your air-conditioned home.

What is the appropriate humidity level for an indoor environment?

Indoor humidity levels should be between 30 and 60 per cent. You can determine if the humidity in your home is too high by:

  • Testing the humidity in your home with a hygrometer, available at most home improvement stores.
  • Check your windows for condensation and your walls and ceilings for moisture or mould.

Indoor humidity can become too high when outdoor humidity is high and outdoor air enters the home, such as through open windows or poor seals on windows and doors.
Indoor humidity can also be affected by activities that increase humidity, such as cooking, showering, or hanging laundry to dry.

Does the air conditioner control the humidity?

The thermostat controls your air conditioner, which measures temperature, not humidity. The thermostat tells the air conditioner to switch on when the temperature climbs above a specific point.

 

While the air conditioner is working, some moisture is removed from the air.
However, air conditioners are not explicitly designed to control humidity, so they can’t always handle the amount of water vapour in the air.

If you lower the temperature on the thermostat, your air conditioner won’t do a better job of removing moisture from the air.

What happens to my air conditioner if it’s too humid in the home?

If your home is too humid, your air conditioner will have to work overtime to keep you comfortable.
You’ll probably be tempted to turn the thermostat down further than you usually would to get relief from the oppressive humidity.
But an overworked air conditioner operates less efficiently and requires more frequent maintenance.
As a result, the unit’s life shortens, and energy bills increase.
