The Heat is ON!

Posted by Melodie Elliott on Wed, Jun 15, 2016 @ 01:12 PM

The official start to summer is on Monday, June 20th, but a good portion of the country is going to experience a huge heat wave BEFORE then. According to AccuWeather reports and Senior Meteorologist Ken Clark, the forecast for this week includes historic heat.

Full report here: http://bit.ly/25TH2zp

"Heat will build to dangerous and record-challenging levels in much of the southwestern United States toward this weekend and into early next week.

Temperatures will climb well past 100 F in parts of California, Nevada, Utah, Colorado, Kansas, Texas, Oklahoma, New Mexico and Arizona with the worst days of heat likely from Saturday to Tuesday.

However, the heat will not stop there.

'A truly historic heat wave is likely to bring intense and all-time record challenging heat to a large part of the Southwest this weekend into next week,' says Clark."

As we talk about regularly, the danger of heat stress and illness is real AND it CAN be prevented with precautions. Remember to protect yourself from sun and hot weather while you’re outdoors. Normally, the body cools itself by sweating, but when the weather is particularly hot and humid, you may not sweat enough to keep yourself cool. When one’s body temperature increases too much, heat-related illnesses can occur.

Here are a few tips  to keep yourself and your loved ones safe this summer:

* Choose your outdoor time wisely. Whenever possible, avoid spending time outside during the hottest parts of the day, typically noon to 5 p.m. Choose outdoor activities that you can enjoy in the early morning or evening, such as grilling or going for a walk. 

* Keep everyone hydrated. When the weather is hot, it’s more important than ever to ensure everyone in the family – from children and pets to parents and grandparents – gets enough water. While outdoors, be sure to have ample bottled water on hand and don’t forget to keep your pet’s bowl filled— especially outdoors.

* Leverage cooling technology to make outdoor spaces more comfortable. Sometimes, you have to be outside during hotter times of day. Keeping cool is key. Portable evaporative coolers like the Portacool Cyclone 1000, use the natural process of evaporation to make outdoor spaces more comfortable during hot weather. As discussed last week, these evaporative coolers move water over evaporative cooling media to produce chilled air that provides a noticeable difference. This can make outdoor spaces such as the patio, deck or garage more bearable in the heat. 

* Seek shade. If your patio or deck isn’t covered, use movable umbrellas or awnings to create plenty of shade. Going to a ballgame or the beach? Take an umbrella to shield you from the sun, or wear a wide-brimmed hat to keep the sun off your face.

* Choose weather-smart attire. When the weather’s very hot and the sun is bright, choose loose-fitting clothing made from lightweight materials and opt for lighter colors. This type of clothing will be more comfortable when you sweat, and lighter colors reflect heat more efficiently. If you’ll be working outdoors for any length of time, consider long-sleeved shirts and long pants in moisture-wicking materials to help shield your skin from sun exposure.

* Don’t overdo it with exercise. While vigorous exercise has many benefits, engaging in strenuous activity in extreme heat can do far more harm than good. If you enjoy an outdoor run or have yardwork to do, try to reserve it for the coolest times of day—early morning and evening. Consider taking your exercise routine indoors to a gym or your own living room when temperatures are very hot.

A Refresher Course: What is Evaporative Cooling?

Posted by Melodie Elliott on Thu, May 26, 2016 @ 03:55 PM

Ah, the sultry days of summer are just around the corner. Depending on where you live, the mercury may already be rising. It is helpful to know your cooling options. Today, many people are familiar with traditional cooling methods ranging from air-conditioning (AC) to fans. AC works in closed spaces where the recirculated cool air can be maximized with use of refrigerant and a compressor. Fans – both oscillating and ceiling options - generate air but it is not chilled in any capacity.   

What about evaporative cooling? What is it exactly? Evaporative cooling is, quite simply, cooling with water.  A few relatable examples of evaporative cooling at work is the cooling sensation felt when climbing out of a swimming pool, perspiration as a form of natural cooling to the body or feeling the cool breeze blowing across a lake. By evaporating water, the temperature of the air in contact with the liquid water will lower as an endothermic reaction takes place.  During this reaction, the liquid water changes to a gas and the temperature of the air lowers. 

A portable evaporative cooler essentially works off this principle by acting as a cooling fan that uses water, a pump and a wetted surface to create the naturally occurring process of evaporation to cool warm air and drop temperatures.  By pulling air across water, the temperature of the air will lower.  A control system within the evaporative cooler operates the pump to assist in creating this effect and the fan distributes the cool air.

One unique aspect of the evaporative cooler is that it actually works best with a supply of outside ambient air to deliver a temperature reduction and cooling effects.  While evaporative coolers achieve significant temperature drops in more arid climates and drier spaces, they provide relief from the heat in any climate.  For example, in regions where relative humidity reaches 70% at midday with temperatures over 90 degrees Fahrenheit, evaporative coolers have been shown to offer noteworthy relief. Given that relative humidity is lowest in the afternoon when the temperature is at its highest, an effective evaporative cooling scenario is achievable.

Example: Evaporative coolers have been proven to deliver a temperature reduction from 8 to 10 degrees in the morning in the highest humidity regions (Miami, New Orleans, or Boston), and  up to 12 to 15 degrees later in the day when the  relative humidity goes down as the temperature goes up.

The technology at the center of an evaporative cooling system is the evaporative media (e.g. the surface) that collects water. Air passes through the media and is cooled as the water evaporates. The evaporative media is specially treated to prevent deterioration and ensure a long service life.  A special water distribution system spreads water over the surface of the media within the cooling unit to ensure a uniform water supply.  This keeps the entire air to contact surface thoroughly wet. A control system operates the water pump and distributes the cool air.  What difference does this evaporative media make? We’ll take a deeper look at that in next week’s post. Stay tuned.
