The Refrigeration System in Your Walk-In Freezer

The Refrigeration System in Your Walk-In Freezer

freezerWhen we are looking at walk-in freezers for your commercial restaurant equipment list, we need to focus, also, on the most advanced portion of the animal, the refrigeration system itself.  “The most complex part of the unit is the refrigeration system. To bring it down to basics, you’ll want to know how much power the system will need in order to operate, where that power will be coming from, and how much clearance and ventilation the system will need. All of these are things that could affect the configuration that you choose.”

The size you decide upon will have something to do with what the Commercial Refrigeration in St Louis near Maryland Heights requires.  “Smaller walk-in coolers typically require a 1/2 hp compressor to hold temperatures at or below 41 degrees Fahrenheit. Walk-in freezers often need a larger compressor—around 1 hp—to maintain those colder temperatures.”  Size and efficiency are a toss up and balancing act as they are in so many other industries as well.  So, it is safe to assume that the larger the walk-in freezer, the more powerful the refrigeration system will need to be.  This will discourage you from buying a freezer that is more space than you really need since you will give up not only physical real estate for it, but also more money, a larger refrigeration system and a higher cost to operate.

While shopping around, also keep in mind that your space may limit your options when it comes to the location of the refrigeration system, as it is not only the space of the freezer you need to consider, but that the refrigeration system increases in size as well. If you have a very low ceiling, or can’t install the proper ventilation, you may need to go with a side-mounted or remote configuration.  Don’t forget that the ventilation takes up room too.  Either way, if you call on experts, such as your St Louis Refrigeration Installation near Maryland Heights, what seems a bit overwhelming in terms of content and vastness of information, can be cleared up in a jiffy.

Proper Ventilation Helps Ensure High Air Quality for HVAC Systems

Proper Ventilation Helps Ensure High Air Quality for HVAC Systems

commercial HVAC in MOWhether you are in the process of designing and building, retrofitting, upgrading, or adding to an existing facility, there is a wide range of solutions to meet your unique challenge. It is important to seek out the best available technology to preserve resources, slash heating and ventilation costs, and shrink your environmental footprint. For help with commercial HVAC installation near Chesterfield contact American Services for help.

For your next ventilation project, start with the premise that almost every building or enclosure requires some type of ventilation to prevent the buildup of harmful gases and contaminants. Fresh air is needed to replace stale air. New air is needed to replace exhausted air. At the same time, depending on the climate and season, tempered air is needed to satisfy your ventilation requirements. Design strategy to optimize indoor air quality (IAQ) by delivering cost effective, environmentally sensitive, reliable, and durable customer-driven solutions.

Proper ventilation requires also that there be a movement or circulation of the air within the space and that the temperature and humidity be maintained within a range that allows adequate evaporation of perspiration from the skin. It might be the case that the discomfort, headache, and lethargy commonly associated with poor ventilation were caused entirely by the increase in the amount of carbon dioxide and the decrease in the oxygen content of the air.

A simple roof ventilator is essentially an opening in the roof with a cover to keep out rain and to prevent winds from interfering with its functioning. Natural convection is an appreciable aid to ventilation in a large building only if it contains sources of large amounts of heat. A further useful adjunct is a fan in the roof ventilator. The addition of distribution ducts to the fan and a system for forcing air into the building provides greater efficiency.

Ventilation & Customizable Preventative Cooling Maintenance

Ventilation & Customizable Preventative Cooling Maintenance

commercial cooling service in MOAmerican Services offers customizable preventative cooling maintenance in St. Louis County for many types of commercial establishments including; restaurants, hospitals, school, supermarkets, commercial offices, warehouse spaces, and more.

What many business owners may not be aware of is that fact that proper ventilation is the least expensive and most energy efficient methods of cooling buildings.  The way that proper ventilation works is that it prevents heat build-up in your office or commercial building.  Natural ventilation including spot ventilation, ceiling fans, or window fans may be the only method of cooling necessary, depending on your geographic location.  For some areas that cool off sufficiently at night, simply providing ventilation to open your commercial space up and allow the outside cooled air in, can keep the area sufficiently cool when the temperature rises during the day.

Even in very hot climates, “interior ventilation is ineffective in hot, humid climates where temperature swings between day and night are small. In these climates, natural ventilation of your attic (often required by building codes) will help to reduce your use of air conditioning, and attic fans may also prove beneficial,” says

There are 3 principals of ventilation for cooling that should be given attention when using this cost efficient method of cooling, including; keeping heat outside, using spot ventilation, and avoiding heat generating activities indoors when possible.

Landscaping the building to provide a lot of shade is another way of passively keeping commercial spaces cool without the need to reach in your pocket to pay huge energy bills.  Using light colored materials for the roof will also help to reduce heat in your building by reflecting it.  And last but not least, proper insulation will keep heat out during the day and trap the cool air from cool nights inside.

Optimizing your HVAC System at School

Optimizing your HVAC System at School


HVAC system in MOAmerican Services HVAC installation near Fenton knows that the heating and cooling of a school can keep operating costs high, so it’s important to not only choose the right HVAC system, but to make sure it is being used properly.  If you’re looking to drive heating and cooling costs down, then there are some steps you can take to make sure your HVAC system is operating efficiently.

One thing to always keep in mind is to use natural ventilation to help control costs and also to inject fresh air into the building.  This is actually covered in a government stan              dard for public buildings called, ASHRAE Standard 62.1-2010, which speaks to proper ventilation for indoor air quality.  While this is a government mandate, it also can be utilized to cut down on costs.  Natural ventilation can be used to control the ambient temperature in the building and also cut down on costs by cooling the space naturally.  Of course caution must be taken to insure that outdoor pollutants are properly filtered and humidity is controlled.  Otherwise contamination of the indoor air and mold from the humidity can begin to develop.  An HVAC system with vent filtration and humidity controls will help to reduce or even eliminate any issues.

One possibility for brining in natural air actually serves a two fold purpose, skylights.  Vented skylights with automated controls can be an expensive after construction addition, but during a build they can certainly be more cost effective.  Skylights, especially in a school offer the benefit of natural light, which not only brightens up the space, but can also help to control energy costs.  Adding vented skylights allows users to add natural light and outside air depending on outside air and weather conditions.

Putting  natural air into a closed environment can benefit occupants and help to reduce costs.  In this tough economy that just might be the solution schools need.

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.
