Understanding Relative Humidity and Your AC

Humidity – the amount of moisture in the air – is of tremendous importance for your comfort and for your health. It also impacts the energy costs of operating your AC system, the biggest energy hog in your home. When you reduce the humidity in your home, you also reduce the risk of mold and mildew growth. When humidity is low, you also feel cooler in summer and warmer in winter.

Humidity is a complicated topic.  There is always some moisture in the air. Relative humidity is the amount of moisture relative to the amount of moisture the air can hold. If the relative humidity is 50%, then it is half “full” of water. If the relative humidity is 100%, it cannot “hold” more water. When rain clouds form, they are at 100 % humidity, but the ground-level humidity could be much less.  If the air around you is at 100% humidity, it is holding all the water it can. It does not mean it is raining, just that the air is saturated with water!

When relative humidity is low, we feel cooler because sweat evaporates easily. People feel most comfortable when the relative humidity is around 50%. Your AC system is designed to de-humidify the air, so it is important that it does this properly or you will not feel comfortable even if the temperature is cool. You will also find yourself sneezing and coughing, because humidity promotes the growth of allergens. If humidity is too low, you will have a dry throat and be trouble by static electricity as well as dry, itching skin.

As air cools, it become less able to hold water. At a certain temperature, it will condense into water (the dew point) or ice (the frost point). The dew point varies depending on the relative humidity. Currently, (October), the dew point in South Florida is 65 degrees… meaning condensation will form at this temperature. In Maine, on the other hand, the dew point is now 40 degrees.

Normally, during hot weather, condensation will form on the outside of your windows if you run the AC very cold. This is because hot air can hold more water than colder air. When the air touches your cold windows, it condenses. Indoor humidity that is too low is more common during winter, because cooler temperatures and heating cycles lower moisture in the air more rapidly. In the summer, relative humidity that is too high is a more common issue.

Condensation on the inside of your windows is a sign that something is imbalanced in your AC system. Your AC system includes your entire home, so if you have leaky windows that will affect the relative humidity inside your home and how hard your AC has to work to remove moisture. You buy humidity gauges (hygrometers) for around $15 apiece to measure the amount of relative humidity in the air. Buy several, leave them in place, check the relative humidity, and then swap the positions to check the accuracy of your readings.  If the temperature is at 76 degrees, the relative humidity should be around 50%.  In the winter, it should be no lower than 30%.

There is a recipe for appetizing restaurant lighting, and sometimes it can make or break a restaurant. LED bulbs, which come in a variety of shapes and colors, are an effective way to modulate mood. They are available in large sizes to create a big impact in focal features. Some are waterproof, so you can use them in waterfalls, water walls, and fountains to create the perfect splash. If you have an Italian restaurant, consider using red and green LED lights to make a statement.

Open show kitchens are popular in restaurants, but offer a unique lighting challenge. The kitchen must be a bright, clear-light work environment, which is fine with CFLs, but the food must be delicious looking as it is made and waits under heat lamps to be served, which pose a problem with CFLs. We offer energy-efficient light bulbs in a variety of colors to make your food look as good as it tastes. These include a combination of kitchen and over-the-table lighting to set the right mood in your restaurant. Did you know that people have a bigger appetite when the light is dim? It’s true. So even if you have a bright show kitchen, keep over the table lighting subdued. And put your grill front and center of your show kitchen. Guests like the drama and the orange-red of the flames as your chefs work helps take the chill off bluish CFL bulbs. We offer halogen lights that are ideal for kitchens and cast a clean, bright light with savings of up to 80% on energy costs.

Restaurants with big windows are fabulous during the daytime, when natural lighting (the ideal type of lighting made by Mother Nature herself) floods the space and food prep areas. Many restaurants are not so lucky, particularly those located in the interiors of shopping malls. To mimic the warm of natural sunlight, install large overhead fixtures with alabaster-colored shades and combine with wall scone floods and strategic LED lights. Newer restaurant lighting fixtures include honeycomb modules and chandeliers that use gorgeous LED modules with diffusers. Available in a range of colors. LED modules can create dramatic effects and are useful in restaurant seating areas. GE makes super-mini bulbs for low-watt fixtures that provide richness and accuracy of color. These bulbs retrofit with existing systems and can burn up to 15,000 hours.

Architectural LED power grids are a fast and simple way to install energy-efficient, bright LEDs in a variety of colors. These illuminated grids are up to 64% more efficient than fluorescent, have no lead, mercury, or glass and offer a 50,000 hour lifetime.The interlocking grids can be quickly constructed into backlighting such as behind a cocktail bar or on ceilings for an overall illumination… and they come in a wide variety of colors.

How To Light Hotel Rooms… To Brighten Guest Satisfaction

Hotels know the cost savings provided by replacing inefficient incandescent lighting with compact-fluorescent bulbs. But guest complaints are common because CFLs can have an unpleasant light quality. They also have a short lag before they reach full brightness, which guests dislike when walking into an unfamiliar space, including a hotel room. To keep guests happy requires a little extra care when choosing CFLs and CFL fixtures, but it can mean saving money with risking guest satisfaction.

Bathrooms and Entries: Always choose a CFL that warms up to full brightness in 30 seconds or less. Some CFL bulbs take longer than others to warm up, but there are newer brands that have instant-on technology. This is especially important for the entry light when a guest first flicks on the light when entering the hotel room, and in hotel bathrooms were light is a safety issue.

Size and Shape: Big, bulky spiral CFLs look cheap in an upscale hotel environment. Choose the smaller, compact size CFL bulbs for hotel room fixtures and lamps. If a bulb is readily visible, such as in a bedside lamp, there are CFL bulbs designed to resemble incandescent bulbs that give a much better impression. You can also get CFLs to fit and look good in chandeliers, ceiling fans, and wall-mounted swing lamps. There is no reason to make guests think “cheap!” every time they switch on a light, when we offer energy-saving bulbs for every possible need.

Dimmable and 3-Way Fixtures: Guests usually want and expect these fixtures in their hotel room. For maximum guest comfort, include a dimmable general purpose light, such as a ceiling light, and at least one 3-way table lamp near a reading chair or bedside. Only CFLs that are specifically designated as dimmable will work in a dimmable light fixture. Other CFLs will flicker and burn out if used with a dimmer switch. Likewise, 3-way CFLs are required for 3-way fixtures. Standard CFLs will not turn on until the third click of the lamp switch, which is an annoying guest experience and makes them think maintenance is not doing a good job of keeping the room fresh and in good working order.

Color Temperature: The color that CFLs emit can be unpleasant, even glaring. Choose bulbs in the 2700-3000K color temperature range, especially in bathrooms and near hotel room mirrors. The light color is similar to incandescent bulbs and will not make your guests look washed out and unhealthy when they look in the mirror as they brush their teeth.

Colored Lampshades: While not strictly part of your bulb choice, the lampshade has a big influence on light color. Trying using lampshades in pink-beige tones for a warmer, more flattering tone. Your guests won’t know why, but the illumination will be more pleasant and cast a more hospitable glow.

LEDs – LED bulbs come in the same sizes and shapes as incandescent bulbs, can last over 22 years if burned 3 hours a day, and offer a multi-directional light output with clean, bright 3,000K color. With no mercury and great energy savings of 77% compared to incandescent, LED bulbs are the perfect one-to-one replacement bulb for just about any hotel room fixture.

LED Strip lights are another way to add light and a design to a hotel guest room. By adding these strip lights to the top of a headboard you add extra lighting and ambience not to mention they are easy to hide.

Hurricane Season… Are you prepared?

Hurricane Season is here the Eastern Pacific season began May 15 while Central Pacific began June 1. The Atlantic hurricane season also began June 1 and just like the pacific ends in November 30.

During the season it’s always a good idea to begin your preparations early, because even though during a hurricane watch or warning you have time to track and prepare. We all wait till the last minute since we are not really sure if the hurricane, will actually hit our area or if it will make a last minute track change. And then we spend hours in line at the stores getting our last minute supplies. Only to figure out the store has run out of some of the supplies. So that is why preparing early is important it saves you time and money.

I have been living in Florida my whole life and, I understand first hand that we as consumers are weary of preparing early. I am one of those people who have waited for the last minute, because the times I have prepared early nothing happens thankfully. However I have also learned that when I don’t prepare things happen and then I have nothing. So this year I decided that I would prepare early and if, nothing happen which I would much rather, I could use these supplies year round.

The truth is that hurricane supplies don’t need to be purchased just for hurricanes. The supplies are very versatile and can be used in just about every situation. Like a couple of months ago a flashlight would have been handy when I lost power in my house. The power wasn’t caused by any kind of disaster just old hardware. I spent two nights with no power and of course no flashlight. Cause who needs one right?

So when deciding to purchase your supplies don’t think of it as just hurricane supplies think of them as just in case supplies.

  • Here is a small list of supplies.
  • Flashlights & extra bulbs
  • Battery operated radio
  • Battery operated lanterns
  • Batteries (different sizes)
  • First Aid Kit
  • Rain Gear
  • Plastic bags
  • Can openers
  • Water
  • Generator (if affordable)
  • Extra medicines
  • Gas
  • Cash

We have a wide selection of hurricane or just in case supplies, visit us at www.adlsupply.com/hurricane-supplies/
