Geothermal Heating & Cooling Systems – How do they work?

Geothermal Heating & Cooling Systems – How do they work?

Clean Energy Concept Education as a Art AbstractGeothermal heating and cooling systems use the heat that is naturally created by the Earth to stabilize temperature.  These systems are highly efficient, have very little cost associated with daily use, and are a green form of energy.  Today, the team at American Services wants to give you a quick review of how these systems work. Let’s get started!

Under ground, the temperature of water holds at a steady, more comfortable temperature that averages between 42 and 80 degrees Fahrenheit depending on what part of the country you are in.  This temperature holds unchanged all year long despite the season or air temperature above ground.  Geothermal systems tap into that constant temperature via either a closed or open loop system and heat pumps. With a close loop system, a set of underground pipes are laid and filled with refrigerant.  The refrigerant then runs through the pipes (thanks to the use of a heat pump) and absorbs heat from the water underground.  In the winter, the system absorbs heat that is used to warm the air and in the summer the system absorbs the cold that is used to cool the air.  With an open loop system, the same process happens but instead of refrigerant pond or well water is used to transfer the hot or cold.

Geothermal systems are friendly to the environment because they use a naturally occurring source to regulate temperature.  These systems are more costly to install, yet the monthly energy use is much lower and results in more affordable energy bills.

Fryer Maintenance – How to Clean Your Commercial Deep Fryer!

Fryer Maintenance – How to Clean Your Commercial Deep Fryer!

Deep FryerRestaurant owners that utilize the use of a deep fryer, need to remember that their commercial deep fryer unit has a set of important maintenance specifications that need to be continually recognized.  Today, the team at American Services is going to inform you on how to perform the cleaning of a commercial deep fryer.  Let’s get started!

  1.  First, you must turn off and unplug your deep fryer unit.  The unit needs to cool to a temperature below 150 degrees Fahrenheit before you can begin to clean it.
  2. Use tools like paper towels, a scraper, and some soapy water to get the outside of the fryer clean.
  3. Make sure to remove the fryer baskets and run them through your dishwasher for a thorough clean.
  4. Place a container large enough to catch all of the oil from the inside of your fryer under the fryer drain.  Keep your any local regulations in mind when disposing of the oil you have removed.
  5. Use a five-gallon bucket to make a cleaning solution of water and grease-cutting dish soap.  If your fryer is especially dirty, be sure to add your favorite commercial de-greaser to the solution you have made.
  6. Using an abrasive scrubbing pad and a spatula, scrub the inside of the unit with the cleaning solution you have made.
  7. Once you are finished scrubbing, rinse the unit with a water and vinegar mix.  This will remove the soap residue.  It’s important to make your solution from more vinegar than water and to have your drain open while cleaning.  Make sure the liquid can drain into a container or a floor drain to avoid a huge mess.
  8. Now you are ready to close your drain, dry the inside of the fryer, fill it back up with oil, and continue serving your customers!

10 Tips for Safely Heating Foods in your Commercial Kitchen

heating equipment for commercial kitchens in MOAmerican Services heating and cooking equipment installation near Overland knows that for restaurant owners, keeping food hot is a must to maintain the flavor and safety is a number one priority.

The following guidelines will help restaurant owners ensure that they follow safety guidelines to ensure proper heating of prepared foods;

  • Stir foods and keep them covered to help evenly distribute the heat
  • Check temperature at least twice with a meat thermometer
  • Make sure food temperatures remain above 140 degrees Fahrenheit to keep bacteria at bay
  • Any food that has been kept at a temperature below 140 for two hours or more should be tossed
  • Only prepare the amount of food needed to ensure left overs don’t go bad

Commercial Good Heating Equipment

There are several types of heating equipment for commercial kitchens that have been designed to keep hot food hot.  Tips for safe heating of hot foods include;

  • It’s important to preheat any heating equipment before utilizing it for holding hot foods.  Placing hot foods in a cold heating receptacle could cause food to reach unsafe temperatures which could put the safety level of cooked foods at risk.
  • Keep in mind that different types of food require specific equipment in order to maintain the right temperature
  • Remember to stir food and keep it covered in order to evenly distribute and maintain proper heat levels.
  • Consider installing drawer warmers, overhead warmers, or merchandise cabinets in a self-serve food bar, while buffet style facilities may prefer to use chafing dishes and countertop warmers.
  • Delicatessen style food service businesses may want to consider using round warmers in the front of the restaurant and holding cabinets in the kitchen.

Supplemental Industrial Cooling Choices

Supplemental Industrial Cooling Choices

cooling HVAC in MOWhen it comes time to deciding how to cool down a large space, there are several options to consider.  Gone are the days when you just bought the largest HVAC system you could find and hoped that it did the job, now you have everything from misting fans to portable cooling units that can be focused on your high heat areas. 

One possible solution is to install an evaporative cooling system.  The principle behind this is that a large high velocity fan is installed and uses evaporated water to cool the air down, by as much as 15 degrees Fahrenheit.  This process is far cheaper than using a HVAC system by itself, which uses a large amount of energy and coolant to cool the air as it comes out of the ducts.  Now of course the evaporative cooling system won’t necessarily replace HVAC in some climates, but it can be a nice supplemental system to reduce operating costs.  In addition, for climates where the air is dry, you get the added benefit of adding humidity to the air, which is good for the workers overall.  These systems are also fairly simple to install and can be reconfigured as the demand arises.

Another option to help mitigate cooling costs is to install industrial ceiling fans.  Much like the fans you would install at home, only sized for larger environments.  These fans have massive blades that are specifically engineered to move great quantities of air, in order to improve circulation in a building.  The fans are also designed to run at low speed, which means they can still push large volumes of air, but use a small amount of energy and minimal force that translates to less wear and tear on the motor.  The fans can also be used in both summertime and wintertime by effectively moving either cool or heated air and saving both heating and cooling costs.

A final possibility for cooling a large warehouse of factory environment is to utilize portable systems.  This can be anything from a portable AC unit to cool down an office to a fan that is used in specific heat generating areas.  Manufacturers do make portable evaporative cooling fans that come in a variety of sizes and powers to adapt to almost any environment.  And of course as the needs change in the environment these fans can be wheeled around to where they are needed most.

Supplemental cooling systems are a great way to minimize costs and help insure that your employees are working in a comfortable environment.  Not only they will work well for your bottom line, but should increase production as well.  With that in mind, supplemental cooling systems provide a great investment, and a nice return on your money.

Installation of Restaurant Equipment – Ice Machines

Installation of Restaurant Equipment – Ice Machines

ice machines in MOAmerican Services knows that ice machines are a necessity for customer satisfaction and productivity in your operation. Purchasing a new ice machine can be an exciting experience and a relief to know that your operation can continue providing a service to your customers. Although restaurant equipment is expensive you can save a little money by installing your new ice machine yourself. There are just a few basics to understand to ensure your ice machine will function properly once installed.

The most important decision will be the location of your commercial ice machine, which should be free of airborne and other contaminants. For safety and sanitary reasons, you do not want foreign matter to transfer to the ice. The air temperature must also be considered. Air temperature between 35 degrees Fahrenheit and 110 degrees Fahrenheit will ensure your system runs efficiently without overheating, or freezing up. Additionally, you do not want the location of your ice machine to be hear heat-generating equipment or in direct sunlight. Specifically, do not place it next to ovens, steamers, grills, or steam tables. This will cause your system to overwork itself in an attempt to keep the ice cold inside of the machine. An overworked machine will reduce the life of the components and increase the number of repairs required throughout the year. Additionally, the location you choose must not obstruct air flow through or around the ice machine. Air cooled equipment will require larger clearance measurements around the system where as water cooled ice machines will allow the machine to fit within a more confined space. Additionally, always check the electrical requirements to ensure your location can accommodate the ice machine.

How Geothermal Heating Systems Work

How Geothermal Heating Systems  Work

commercial heating services in MissouriAmerican Services Heating systems installation in Wentzville knows that geothermal heating systems work in a very unique way to “naturally” provide a heat source to commercial buildings or other environments. The earth stores heat within it. In fact, it maintains that heat at about 50 to 70 degrees Fahrenheit. This is a stable figure, meaning it is completely renewable when it is tapped into, and it is a natural source, there are no chemicals or side effects from using this type of heat source. Yet it is powerful and plentiful enough to heat an entire building without furnaces or boilers.

In order to utilize the geothermal heat that is underground, scientists have found that they can literally pump it out with the use of a geothermal heating system. A heat pump is used.

It is a  mechanical device that transfers the heat from one place to the next. In this scenario it’s as simple as pulling up the heat from the Earth’s soil and then transferring it directly into the building installation. The heat is transferred by using a network of tubes throughout the building connecting to the heat source. These tubes are called closed loops and are filled with a liquid such as a refrigerant, water,  or occasionally antifreeze. The liquid that is within these tubes will travel into the ground, absorb the earth’s natural heat source and then it is recirculated through the system back into the building. The heat is then released from the liquid element and is transferred into the building. In this continuous circuit the liquid element then travels back down to the earth’s heat source and the process just keeps repeating itself. This loop system allows for geothermal heating systems to provide a constant flow of heat to the buildings.

Heat That Cools

Not only can geothermal heating systems provide heat to a building, but it can actually cool the area off as well. The system is quite the same in that the same loop is used, only this time it is in reverse. The valves within the system allow it to be switched to cool instead of to heat. Now the heat from the building is absorbed through the tubes containing the very same liquid elements and cycled out of the building. During the summer months this allows for an additional benefit because the earth does not need to be heated and there is still a large amount of heat in the liquid, Energy can be tapped into in order to have it heat the water for the building. This eliminates the need for a hot water tank or heater operations which saves significant energy efficiency and utility costs.

Commercial Cooling Solutions for Work Spaces

Commercial Cooling Solutions for Work Spaces

cooling service in MOAmerican Services Commercial Cooling Installation in Overland knows that if your work space is full of heat generating electrical components and electronic devices, then you will need some heat removal systems. The comfort and wellbeing of your employees and safe operation of your equipment will depend on this. Conditioned air and proper ventilation are essential steps in creating a safe air conditioned environment that removes heat and circulates fresh air.

Some examples of these commercial buildings might be Schools, IT firms or manufacturing plants.

There are two types of commercial and industrial air conditioning. Modern cooling system technology uses ductless or split air conditioning. This allows the cooling unit and condenser to be located in a different location most generally on the rooftop. The cooling is thermostat controlled. Ducted cooling systems are inefficient and no longer installed in commercial applications.

Air cooling, water cooling, glycol cooling, and chilled water cooling are just a few of the cooling technologies still available today
Air cooled systems: widely used for its convenient ductless setup. The condensing unit is usually located outside, this helps with the exchange of the fresh air and removing of hot air. Because the cooling pipes are limited in length consideration must be made between workspace and the roof.
Glycol Cooling systems: though a very sophisticated cooling system
which produces temperatures below 50 degrees Fahrenheit. The coolant used in this system is Glycol it can be implemented over long distances and provide cooling to many workspaces with one condenser. This system requires more maintenance and constant monitoring of quality and quantity of the coolant Glycol.

Water cool systems: a cooling tower is used cool water which gets pushed back to the heat exchanger in the work environment. Benefits are multiple workstations can be cooled with just one single cooling tower. The cost of maintenance of cooling tower and quality of water may not be the best economic fit for your building.

Chilled water systems have a greater heat removing capacity. Cools larger areas with a greater efficiency and it only requires one
chiller plant. Possible setbacks can be installation charges; these are “extremely expensive” systems. Another concern should be the removal of most the moisture in the air (employee health problems). Careful consideration of your current building and its infrastructure a combination of one or more of these systems can be used to provide your air conditioning cooling systems.


Refrigeration Safety Principals

Refrigeration Safety Principals

refrigeration installation in Jefferson CountyAmerican Services refrigeration repair service in MO,  as well as technicians  working  daily with refrigerant systems, know full well the potential hazards the refrigerants pose while installing, maintaining, and servicing the systems.  All of these operations, when  mishandled can lead to serious injury. Today’s classification system which includes toxicity rating, based on exposure of the individual during his working life without incurring ill effects.  Refrigerants in the A  class have no toxicity at concentrations at or below 400 ppm. The 1 represents flammability characteristics with the parameters being tested in there at 14.7, and 65, degrees Fahrenheit. Not all refrigerants in use today carry the safety classifications mentioned above.  This is a safety factor a technician should keep in mind when operating, with refrigerants outside the a 1 rating. Even below 20 degrees below 0, evaporation can happen, safety hazards, can still occur if abused, or handled roughly. Make sure all gaskets belonging to refrigerant hoses and other related equipment are maintained in good working order. If not split hoses can occur causing liquid refrigerant spray out, possibly resulting in severe frostbite. Technicians also need to use extreme caution with the schrader valve. Purchasing hoses with low lost fittings or adapters can reduce this hazard. Overall refrigerants are considered in the non toxic classification, however when operating in an enclosed area be careful not to inhale vapors or use a safety mask. Some symptoms of inhaling vapors include; dizziness, unconsciousness, nausea, irregular heartbeat, and even death which could occur if inhaled long enough. When refrigerants are exposed to heat and high temperatures, decomposed toxic and irritating byproducts are formed. Some of these toxic byproducts are hydrogen chloride hydrogen fluoride for c f c and h.  F c, and CFC, HCFC, HFC.

These vapors are acidic and extremely dangerous, all people should  evacuate the area and ventilate as soon as possible if vapors are released. Removal of any remaining refrigerant, prior to soldering or brazing will prevent this problem.

Another hazard is unsafe handling of cylinders.  Here are some safety handling features; never store cylinders above 130 degrees Fahrenheit, never use the torch on a refrigerant cylinder, never use a cylinder that is rusty or shows a bulge, relief valves should not be tampered with and recovery tanks tested every 5 years. Do not fill cylinders more than 80 percent capacity.

Following these safety steps will reduce injuries caused by refrigerant operation.
