Thermally Driven AC

Thermally Driven AC

thermally drivenWe like to discuss all that is new and pertinent in the area of HVAC on behalf of St Louis American Services company who deals in HVAC sales and service near Edwardsville IL.  Some of the newest designs in the industry were covered last month. Today, we pursue more information to pass along to you.  “Another design that’s recently been implemented is thermally driven air conditioning. An Australian company named Chromasun has produced a low-cost alternative to traditional A/C units.”  This is yet to be a popular, widespread idea in technology, but interesting enough to include here, nonetheless.

Since it is not well known as of yet, it is also not available in the United States at this point.  The reviews and information we read online, however, on behalf of your St Louis HVAC installation, says it should not be long before this is not the case.  “It isn’t a widespread technology yet, and it will likely be several years before this kind of design becomes widely available in the United States. However, thermally driven air conditioning is a system that uses solar energy and is supplemented by natural gas, making it a highly efficient and effective system.”

With a double chiller such as the one is has, this particular design provides more cooling capabilities than any other system out there today.  “In fact, the double-chiller design provides more cooling capabilities than any other system so far, and it eliminates electricity costs altogether.”  This is one innovation in St Louis HVAC near Edwardsville that we recommend you keep your eyes on and plan to see more of in the near future.  In our upcoming posts, we will continue to discuss interesting options in HVAC similar to this thermally driven one.

Heating and Carbon Dioxide Reduction

Heating and Carbon Dioxide Reduction

co2When it comes to heating and cooling in St Louis near Bridgeton, we are working in an ongoing fashion to deliver you the latest information in technology and heating and cooling movements.  Today, we discuss and deliver information regarding the latest in green technology, both to show our appreciation for the energy efficiency, life sustaining movements from the earth’s perspective, and also in the name of keeping you all informed of the latest and greatest technology in the St Louis Heating and Cooling industry.

“Santa Clara University is not only a pantheon of learning in the heart of California’s Silicon Valley, but it’s also a temple of green technology. In April 2011, the university installed 60 rooftop solar collectors to heat and cool its student center. Engineers designed the large-scale array to run the building’s hot water and air conditioning units.”  The heating and cooling method is very efficient and one way that they began down the green HVAC road.  “The system is very efficient. The solar collectors grab the sun’s rays and concentrate their captured energy, heating the building’s water to 200 degrees. University officials expect the system to reduce the building’s natural gas consumption by 70 percent each year and eliminate 34 tons of carbon dioxide from the atmosphere.”

The latter is an interesting bit of information found and reported on behalf of your Heating St Louis Installation and Sales and is worth pointing out as something many don’t see in the solar benefits model.  Solar energy is definitely harnessed for little or no expense after the initial startup, but do people understand the benefits such as drastic reduction in CO2?  Its time we start to see things for what they actually are in the world of efficient energy.

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.

Alternative Heating Sources

Alternative Heating Sources

solor heating in MOAmerican Services Heating and Cooling installation service in Missouri knows that there are many options when it comes to commercial heating systems.

One such option is for heat transfer fluids.  If you are considering solar heating heat transfer systems, be sure to consult the local authority in your area to find out what exactly is required for your geographic area.

Water is one type of substance that is effective as a heat transfer fluid, particularly with its low viscosity property which makes it easy to pump. Drawbacks are its low boiling point and high freezing point, and the fact that water can be corrosive and cause mineral deposits.

Glycol and water mixtures are made up of a 50/50 or 60/40 glycol-to-water ratio. Ethylene and propylene glycol make up the properties of antifreeze.

Hydrocarbon oils have a higher viscosity and lower specific heat than water meaning they need more energy for circulation.  With a low freezing point, these types of oils tend to be relatively less expensive than some others.     The basic categories of hydrocarbon oils are synthetic hydrocarbons, paraffin hydrocarbons, and aromatic refined mineral oils. Synthetic hydrocarbons are relatively nontoxic and require little maintenance. Paraffin hydrocarbons have a wider temperature range between freezing and boiling points than water, but they are toxic and require a double-walled, closed-loop heat exchanger. Aromatic oils are the least viscous of the hydrocarbon oils.

Refrigerants are commonly used in refrigerators, air conditioners, and heat pumps as the primary heat transfer fluid. They generally have a low boiling point and a high heat capacity which enables a small amount of the refrigerant to transfer a large amount of heat very efficiently.

If you currently own a refrigerant-charged solar system that requires maintenance, contact us today at American Services and we will sent out a qualified technician.

Active solar heating uses solar energy to heat transfer fluid or air, which then transfers the solar heat to an interior  storage system for later use. Solar heating systems can be implemented as a supplement to other heating systems such as radiant heating, boilers, heat pumps, or forced-air heating systems.

Active solar heating systems are actually most cost-effective in cold climates that have good solar resources.  Liquid and air systems are good choices for forced air supplemental heating. Note that commercial systems usually come with warranties of 10 years or more and usually last much longer.

Install Renewable Energy Systems

Install Renewable Energy Systems

cement slab floor method in MOAmerican Services heating and cooling instillation and repair near Chesterfield knows that the heat of summer arrives, many commercial businesses start looking for ways to save money on cooling expenses.

One cost effective way to cool industrial buildings is to consider passive solar design to cool your business.   Passive solar systems can really help lower cooling costs when they are designed correctly with overhangs using reflective coatings on windows, exterior walls, and roofs.  Consider placing thermal mass, like concrete slab floors or heat absorbing walls, close to windows for another passive cooling method that can really save on cooling costs.

Solar arrays and wind turbine systems are a couple of examples of renewable energy cost effective systems.  Thinking about installing a renewable energy system at your building, like solar arrays or a wind turbine? Increasing the energy efficiency of your commercial building is a great plan if you are preparing for commercial renewable energy systems.

According to, “efficiency upgrades can shrink the energy load of your building by as much as 35 percent, which will allow you to maximize the proportion of clean power generated on-site at the least cost. In other words, energy efficiency gives you the most bang for your renewable energy buck.”

The Environmental Protection Agency offers the following resource sites to help businesses learn more about renewable energy products at; “EPA’s Green Power Partnership”, or “EPA Guide to Clean Energy Financing Programs”, or “Power Purchase Agreements.”

If you consider the Power Purchase Agreement program, there are actually no upfront costs because according to, “the end-user, don’t own the solar panels. Instead you buy solar power as a service much like you already do for grid-based energy from a utility. At the end of the month, you pay only for the solar energy produced on-site and purchase the remaining energy you need from your utility. A solar energy services firm assumes all performance and economic risks because it owns and maintains the equipment on your site.”

Industrial Heating Retirement Communities

Industrial Heating Retirement Communities

retirement industry heating service in MOAmerican Services serves many industries for heating maintenance and repair in MO such as the retirement industry.  One of the most expensive costs for a retirement community is the heating of water.  Residents, kitchen staff, normal staff and visitors can use large quantities of heated water on any given day and for management staff that means money is literally going down the drain. 

One option for retirement communities looking to save on water heating expenses is to install a solar heating system.  This solution may not work for every geographic location, but even in colder areas there are systems that can be weather-proofed and installed.  For regions that have sun almost all year around, solar heating can be the perfect solution and a cost effective way to maintain hot water supplies 

The concept of solar water heaters is fairly simple.  A photovoltaic cell or a series of them is placed on a roof or high area in order to collect the necessary solar energy.  The panel heats the fluid that is either pumped actively or is passively driven through the system through a convection process.  These two methods are the basic systems; active and passive, and both have there advantages and disadvantages.

The water is stored in a tank that can then send the water throughout any area of the building as it’s needed.  Passive systems require the least amount of equipment and are the easiest to set up, while active systems require an electrical pump in order to move the water through the system.  The choice will often depend on the climate and the building size and configuration.

Solar energy can be a very cost effective solution and offers an endless and consistent supply of energy.  While the expense up front can be daunting, the eventual return on your investment is often worth the initial outlay.  The best way to figure out if this system will work for you is to call a well regarded installation company and an engineer that is familiar with this type of installation.  Not only will you be saving money, but Mother Nature might just smile down on you a  little as well.
