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.

Elaborating Further on Heat Pumps and Central AC

Elaborating Further on Heat Pumps and Central AC

defineMoving onto the second phase of description we are planning on behalf of your St Louis Heating and Cooling installation near Fenton MO, we still have much to explain about your cooling system in your home.  Your air conditioner, to be precise, and though we told you the basics when it comes to the system and how it uses energy to remove actual heat from your space, unfortunately, it isn’t quite that simple.  The process gets quite a bit more complicated with all the controls and valves involved, its effect it rather amazing.  “An air conditioner takes heat from a cooler place and dumps it in a warmer place, seemingly working against the laws of physics. What drives the process, of course, is electricity — quite a lot of it, in fact.”

Our first type of cooling system to discuss, namely because it is the most common, are the central air conditioners and heat pumps designed to cool the entire house. “In each system, a large compressor unit located outside drives the process; an indoor coil filled with refrigerant cools air that is then distributed throughout the house via ducts.”  Heat pumps are then like central air conditioners with the exception of the cycle direction variations.   “Heat pumps are like central air conditioners, except that the cycle can be reversed and used for heating during the winter months.”  We will go into more details on behalf of your St Louis Heating and Cooling sales near Fenton, in regards to heat pumps below.

With a central air conditioner, the same duct system is used with a furnace for forced warm-air heating. In fact, the central air conditioner typically uses the furnace fan to distribute air to the ducts, so there is an overlap and therefore efficiency existent in the system by its simple nature.  Central air conditioners and air source heat pumps in their cooling mode of operation are rated according to their efficiency in the seasons.  We will break down these details in the next couple posts here, on behalf of your Heating sales in St Louis near Fenton MO.

Styles of Electric Cooktops

Styles of Electric Cooktops

electric topWhen buying your next range, stove, oven, cooktop, whichever cooking device you need, you will need to know before your purchase, just which power source you have available to you and also which one you will need and want for your kitchen also.  “The heat output from electric cooktops is measured in watts. Output varies from stove to stove and burner to burner, but the output generally falls somewhere between 1,200 watts for low heat on a small burner and 3,800 BTUs for high heat on a large burner, though we’ve seen outliers on both ends of the spectrum. There are different types of electric cooktops from which you can select.”  Assuming you will go with an electric version of these appliances, we set out to talk about the different choices within, on behalf of your St Louis Cooling and Oven Sales near Chesterfield MO.

“Smoothtop (glass-ceramic cooktop): These cooktops are made of smooth glass-ceramic with heating units under the surface. A built-in sensor lets you know when a burner is still hot. This is important with smooth electric cooking surfaces because the burner doesn’t always turn red if the heat is low.”  These styles can be easily scratched and it is not always a great idea to use some cookware on top, especially super heavy things like cast iron just because of the ease with which you can crack your top.

Electric coil: These burners convert the electricity that runs into the coil into heat. These cooktops contain thermostat sensors that notify y ou when a burner is on, but not necessarily whether it is still hot. Electric coil stoves are notorious for uneven cooking because of uneven distribution of the coil. In short, it is hard to keep the coil perfectly level, which can make all of the food in the pan slide to one side. In addition, electric coil stoves are slow to heat and slow to cool. The advantage, according to your St Louis Cooling service near Chesterfield, however, is definitely the lower price associated with these particular models.

Heating Options in Your Space

Heating Options in Your Space

furnaceIn our research on behalf of your St Louis Industrial Heating near Bridgeton, we have found that there are indeed more than one ways to skin a cat, I mean, heat your space.  Beginning with central heat, we plan to take you through the variety of ways both here and in posts to follow.  Central heating in St Louis involves a furnace.  “The majority of North American households depend on a central furnace to provide heat. A furnace works by blowing heated air through ducts that deliver the warm air to rooms throughout the house via air registers or grills. This type of heating system is called a ducted warm-air or forced warm-air distribution system. It can be powered by electricity, natural gas, or fuel oil.”

Looking inside the gas or oil fueled furnace, we see a sight of fuel being mixed and burned. The flames then heat a metal heat exchanger where the heat is transferred to the surrounding air in an effort to heat the space effectively.  According to your St Louis Heating installation near Bridgeton, the air is then pushed through the heat exchanger by the “air handler’s” furnace fan and then forced into the ductwork which is located downstream of the heat exchanger.

According to experts on HVAC news, “At the furnace, combustion products are vented out of the building through a flue pipe. Older ‘atmospheric’ furnaces vented directly to the atmosphere, and wasted about 30% of the fuel energy just to keep the exhaust hot enough to safely rise through the chimney. Current minimum-efficiency furnaces reduce this waste substantially by using an “inducer” fan to pull the exhaust gases through the heat exchanger and induce draft in the chimney.  If you are looking for service or installation on your heating and cooling systems in St Louis, call your Bridgeton Heating Sales today.

Geothermal Heating

Geothermal Heating

geothermalHeating and cooling in St Louis near Kirkwood is the subject on which we are focused today and we and we want to look in depth at geothermal heat.  “Heat from the earth can be used as an energy source in many ways, from large and complex power stations to small and relatively simple pumping systems. This heat energy, known as geothermal energy, can be found almost anywhere—as far away as remote deep wells in Indonesia and as close as the dirt in our backyards.”

There are many different regions who already utilize geothermal as a means to heat, according to your St Louis Heating and Cooling near Kirkwood MO.  “Many regions of the world are already tapping geothermal energy as an affordable and sustainable solution to reducing dependence on fossil fuels, and the global warming and public health risks that result from their use.”  As of the year 2013, there were reported more than 11,700 megawatts (MW) of large, utility-scale geothermal capacity operating on a global scale.  In addition to the above, according to your St Louis Heating and Cooling near Kirkwood, there were plans for another 11,700 MW just around the corner.

Also discovered in our online research is the fact that these geothermal facilities produced approximately 68 billion kilowatt-hours of electricity, enough to meet the annual needs of more than 6 million typical U.S. households. “Geothermal plants account for more than 25 percent of the electricity produced in both Iceland and El Salvador.”  Looking into the United States, in our research on behalf of your St Louis Heating Service near Kirkwood, we see that we are using more than 3,300 megawatts in eight states.  This makes our country the global leader in installed geothermal capacity.  Eighty percent of the above is installed in the state of California.  Here, there exists more than 40 geothermal plants.

HVAC Roof Standards for Energy Savings

HVAC Roof Standards for Energy Savings

rooftop HVACWriting on behalf of your St Louis HVAC Maintenance near Chesterfield, we have uncovered some very fresh and equally as interesting news to pass your way today.  “The HVACR industry has less than one year to prepare for what the government has deemed the ‘largest energy-saving standard in history’ as the U.S. Department of Energy (DOE’s) energy conservation standards for commercial air conditioners and heat pumps and commercial warm-air furnaces, otherwise known as rooftop units (RTUs), are scheduled to take effect Jan. 1, 2018.”

When it comes to HVAC installation near Chesterfield, apparently all installers as well as sales and commercial repair companies will have to know these standards and keep them in their back pocket, so to speak, at all times.  The rooftop air conditioner standards, such as the ones on low-rise buildings, as in hospitals, schools, and big box department stores will take place in two phases, increasing minimum efficiency by about 10 percent as of Jan. 1, 2018, and by 25-30 percent as of Jan. 1, 2023. Also effective in 2023 will be the standards for new warm-air furnaces that are typically installed in conjunction with commercial air conditioners.

In our HVAC installation in St Louis near Chesterfield research project, we found that there are estimates based upon other estimates, such as the DOE saying that the new rooftop air conditioner standard will save 1.7 trillion kWh over 30 years of sales.  This is actually estimated (once again) on the amount of coal burned in the US to generate electricity for the entire country for one full year.  This is supposed to go beyond any other standard set in place by our government, or any other government for that matter.  We will pay attention to how this plays out, but for now, we simply wanted to relay the information to you, the commercial HVAC consumer.

Maintaining Your Cooling System Part II

Maintaining Your Cooling System Part II

Technician Recording Machine TemperatureIn the previous post, http://www.americanservicesblog.com/cooling/routine-maintenance-for-your-cooling-system/, we discussed the importance of keeping your new and used cooling systems in check through the employment of routing checkups and service, preferably by professionals like those who work for American Services in Bridgeton near Ladue MO.  Some of the exact things that you should ask a cooling maintenance company to handle during your service call are as follows:

“Check thermostat settings to ensure the cooling and heating system keeps you comfortable when you are home and saves energy while you are away.  Tighten all electrical connections and measure voltage and current on motors. Faulty electrical connections can cause unsafe operation of your system and reduce the life of major components.  Lubricate all moving parts. Parts that lack lubrication cause friction in motors and increases the amount of electricity you use.”

Also important for your cooling system routine maintenance near Ladue MO are the following:  overall inspection of the condensate drain in the central cooling air conditioner, furnace or heat pump (while in the cooling mode).  If this is overlooked during routine cooling maintenance, it can lead to plugged drain which can and will cause water damage all throughout your home of business.  Indoor humidity levels can also be affected as a result.  When your cooling system is routinely maintained, you will want the cooling service experts near Ladue MO to also check the controls of the system to ensure proper and safe operation.  They will need to make sure the HVAC system also starts properly, operates and shuts off accordingly as well.

Routine Maintenance for Your Cooling System

Routine Maintenance for Your Cooling System

Front View Of A Man Assembling The Word MaintenanceWhen it comes to your cooling system at home or at work, it is highly recommended that you do what it takes to provide the routine maintenance recommended.  Nothing works to its fullest ability forever, especially systems that are in need of cleaning and checking on a routine basis.  When it comes to your heating and cooling systems in business, commercial and home environments, you will want to consult the owner’s manual for routing requirements.  We will talk about some of those here, on behalf of your Cooling Service and Sales near Wentzville MO.

With routine checks, your cooling system will be less likely to have future problems with unwanted costs attached to them.  Also, routine cooling service will allow your industrial or home HVAC system near Wentzville to always work at its peak performance level.  A little more advice that is specifically from experts who know is as follows, “Contractors get busy once summer and winter come, so it’s best to check the cooling system in the spring and the heating system in the fall. To remember, you might plan the check-ups around the time changes in the spring and fall.”

Here are some things to expect during a routine heating and cooling system check-up near Wentzville MO:  a check of the thermostat’s ability to cool or heat when you are home to a level of comfort, but save you money when you are not home.  All electrical connections should be tightened and voltage and current should be measured on the HVAC motors.  Any type of system with moving parts, HVAC included, should have all the moving parts lubricated.  When things are insufficiently lubricated they cause friction to take place in the motor which will increase the amount of electricity needed to get the job done, thereby making a less efficient system.  Stay tuned for further information regarding your home or office heating and cooling system near Wentzville MO.

Effective and Efficient Cooling

Effective and Efficient Cooling

kitchenTrying to keep your environment cool in the summer can be a challenge, sometimes harder than other times depending on where you live and how you approach the cooling process.  On behalf of your American Services in St Louis near Wentzville MO, we are discussing some ins and outs of cooling.  You have many different options to succeed in cooling your home.  From ventilation in the form of fans and open air, to electricity driven strong AC units, and many things in between, cooling isn’t hard, but it can be inefficient and expensive if you don’t you’re your cards right.  Not just expensive is the cooling process at times, but the service calls surrounding the less than best choices sometimes made by those doing the cooling, as service centers such as American Services of St Louis know all too well.

Things you can avoid to make the cooling of your home the most efficient are listed here:  don’t cook unless you have to and when you do, avoid your oven and lean towards your outdoor grill or microwave, both of which produce little or no heat inside to mess with the cooling process of your home in St Louis.  Go out to eat, or order in.

Believe it or not, even bathing, washing laundry and other everyday activities can be responsible for putting a damper on the cooling of your home as well.  Use a fan to remove the heat and humidity from your bathroom and therefore home, says a representative from the office of American Services in St Louis near Wentzville MO.  If using an electric dryer, or gas dryer, make certain that it is safely and effectively vented to the outside to expel the added heat that it generates.  In conclusion, remember that it doesn’t matter as much how you cool your home, but how you avoid adding heat when doing so in terms of what is most effective and therefore most efficient.

Food Warming & Holding Restaurant Equipment Guide

Food Warming & Holding Restaurant Equipment Guide

Today, the team at American Services wants to inform you regarding the many options you have when looking to add food warming and/or hold equipment to your restaurant.  All of these options give you choices regarding cost, functionality, and customer convenience while providing a safe environment for the food you serve. Let’s get started!

Food Bars vs. Hot Food Tables

When considering the addition of a food bar versus a hot food table, there are a number of things to look at.  Hot food tables provide a functional stainless steel appearance, the ability to keep food hot longer thanks to being electrically powered, an adjustable thermostat that helps maintain an optimal temperature, and options that allow for greater customer service such as end tables, cutting boards, and added work space features.  Food bars offer conveniences like sneeze guards or sun canopies, can be used anywhere since they do not require electricity, can be used on any table top, have the option to be used hot or cold, and provide extra storage within the portable base.

Drawer Warmers vs. Countertop Food Warmers

Drawer warmers are used for holding food in a kitchen since they are not meant to be a display unit.  These units are smaller in size, can be used to hold a variety of different food items, and offer varied temperature control for multiple drawers. Countertop food warmers on the other hand are made to serve customers hot food items in a self-serve environment.  These units can be ordered with a specific holding purpose in mind or can be used in an all-purpose way.

Finally, if you are looking to keep food warm for a short period of time, an overhead warming unit will work best.  When this is the situation, you will be choosing from a heat lamp or heat strip.  Heat lamps work well when you need to heat individual pans of food since they direct heat to one specific location.  Heat strips are used to cover more length of space with even heat and can be used in sized ranging from 18 inches to 12 feet.

As you can see, there are a number of options out there when it comes to food warming and holing.  Ask the Kirkwood area restaurant equipment experts at American Services to help you evaluate your needs in this area of your commercial kitchen today!
