Passive Cooling

Passive Cooling

passiveOn behalf of your St Louis Cooling Repair near South County MO, we are on a regular search for new information and research to pass along to you, in regards to green energy and cost effective, environmentally friendly ways to handle the heating and cooling of your home or business.

Along those lines, did you know that the sun is the ultimate provider of green energy?  A couple things that make it so are the constant and renewable nature of Solar power, the fact that it is not about to run out anytime soon.  There are, according to our research on behalf of your St Louis Cooling Installation near South County, ways in which you can benefit and enjoy the power of solar energy without the effects of direct sunlight.  “Passive solar energy is simple, has little to no moving parts and requires minimal upkeep. Passive solar-energy systems are designed to use natural principals of heat transfer instead of machines such as furnaces and air conditioners [source: Passive Solar Resources].”

It turns out, according to all that we read for your St Louis Cooling Sales and Service near South County, passive solar technology uses the building’s walls, windows and floors to collect, store and release the sun’s energy. “However, passive solar homes still need mechanical equipment, such as a forced-air system or radiant flooring to keep the temperatures cool in the summer and warm in the winter [source: Arizona Solar Center].” Direct gain systems are supposed to be the easiest of them all in terms of installation of cooling capable solar panels in St Louis MO.  In such systems, sunlight passes through windows where the light is converted into thermal energy. The walls and floors directly absorb and store the heat energy. As long as the room temperature is high, the interior of the homes will hold on to the heat. “When the temperature drops at night, the stored heat radiates through the living space.”

Ice and Thermal Driven AC Technology

Ice and Thermal Driven AC Technology

iceThermally-driven air conditioning is the next new technology that we wish to discuss further on behalf of your St Louis Refrigeration Sales near South County MO.  “Chromasun, based out of North Sydney, as in Australia, makes a thermally-driven chiller that provides a low-cost alternative to conventional air-conditioning units, which are electrically driven.”

That seems like a lot to wrap your head around, but essentially these chillers make use of solar energy that, when running short, can be supplemented by natural gas and that lends itself to a greener route and also adds significant value to our discussion about renewable energy in the St Louis Refrigeration Sales world. The company mentioned above makes it own solar panels that generate a high enough temperature to drive a double-effect chiller, which it describes as its most effective system. According to our most recent research on the subject on behalf of your St Louis Refrigeration Service near South County, the company’s double-chiller system is said to provide more cooling than comparative photovoltaic systems, and eliminates electricity costs.

Another cool concept is the ice powered air conditioner. “Ice Energy, based out of Glendale, Calif., uses an ice-powered air-conditioning unit called the Ice Bear to cool buildings and in most cases, reduce a building’s total net energy consumption.”  Keeping up as best we can on the latest technology, your St Louis Refrigeration Maintenance and Sales near South County found the following information worth sharing for green HVAC and Refrigeration evidence in our neck of the woods.   “In a very abbreviated description, the Ice Bear works by freezing 450 gallons of water in a tank overnight and making that available for cooling the next day. When the Ice Bear is switched from its Ice Charging to Ice Cooling mode, it provides cooling for up to six hours. After its ice has melted, the job of cooling reverts back to the building’s conventional commercial A/C unit, which is why the Ice Bear works in conjunction with a conventional unit. The company describes the product as the first effectively loss-less energy solution.”

Using Solar Power in your overall Energy Plan

Using Solar Power in your overall Energy Plan

solor heating in MOAmerican Services HVAC heating and cooling in St. Louis knows that one of the most economical and environmentally ways to heat a building is to use solar power.  And since this green technology has advanced exponentially over the years it has become even more effective and costs less than ever before.

One of the easiest applications for solar power is to use it for the heating of all water in a commercial facility.  Hot water usage can come from showers, bathrooms or even cleaning and manufacturing.  The old fashioned way to heat water has always been by using a water heater that is either powered by propane, natural gas or some other fossil fuel.  The problem with all of these fuels is that there isn’t an endless supply of any of them and therefore the cost to a business can be daunting.  Additionally as fossil fuels become more and more rare and the techniques used to mine them become more expensive the cost is going to continue to rise.  The advantage of using solar power is that it’s a fixed cost with a onetime initial expense and then just maintenance from that point on.

The process to get this all started for a commercial application is fairly simple.  Evacuated tube collectors or a similarly designed solar panel is placed on the roof or high point near the building.  This tube design is particularly important because the solar panels are always facing the sun no matter what angle the sun is at or the time of day.  In addition the simplistic design is solid and offers years of practical use.  The energy is then captured in a solar collector and through a series of tubes and a central controller; the heat is pushed throughout the facility.  This design can be used in a variety of geographic areas and can be just as effective in the winter as it is during those dog days of summer when the sun is always around.

Using a solar panel system to heat water for a commercial building is not only smart business but is good for the earth as well.  Solar energy has been around for years, and continues to supply companies around the world with simple, fast and cheap energy.  If you’re looking to cut costs out of your business and need a simple and time tested solution then solar power might be just what you need.

Advantages of High Density Cooling Towers

Advantages of High Density Cooling Towers

Industrial cooling in MOAmerican Services commercial heating and cooling installation in  St. Louis, knows that there are advantages to the use of high density polyethylene based plastic cooling towers for commercial cooling.

Not only are polyethylene based plastic cooling towers becoming more popular in the U.S., but are growing in popularity in the Middle East as well. Cooling towers manufactured in the U.S. have been integrated into an advanced, solar-powered cooling project taking place in Abu Dhabi.

The Abu Dhabi project is a pilot program which was implemented in order to offer rooftop air conditioning to some of the city’s commercial buildings via concentrated solar panels that will provide clean renewable solar energy to the building during peak demand hours.

“Essentially, the project is using solar power to produce cold water that is used to provide air conditioning,” explained Mohammad Alkarmi, CEO of Limitless International Corp., Raleigh, N.C., the exporting organization that sold the plastic cooling towers to the project’s management. Limitless International is the authorized agent for Delta Cooling Towers in the Middle East

The benefits of the system include significant energy cost savings, but also peak shaving from the rooftop solar cooling technology, which will result in better grid efficiency and reduced emissions.

“We believe that this unique cooling tower technology is the ideal solution for cooling applications in the Middle Eastern countries, where very high temperatures accompanied by high humidity — especially in the gulf region — would prevent most metal cooling towers from lasting very long because they would rust and corrode easily,” Alkarmi said.

The solar powered air conditioning project was a demonstration of the option to use the sun’s energy to provide cooling even in the heat of the desert. “Essentially, they are simply using the hot water that is coming from the solar panels to get cold water from the chiller,” Alkarmi stated.

The cooling towers play a vital role in the overall cooling system performance, and the reliability of the tower reliability was an important consideration when selecting the design.


“The HDPE plastic cooling tower will never rust or corrode, as opposed to either stainless steel or galvanized metal clad models, which will eventually rust and corrode,” Alkarmi said. “The Delta HDPE design does not require any coating or galvanizing or other exterior protection. It simply will never rust or corrode, and will last well over 20 years.”


The warranty coverage period was increased from 15 to 20 years because of the products history of long term performance.
