Natural Refrigerants

Natural Refrigerants

naturalNatural refrigerants are an unexplored subject in the cooling world. According to our recent research on behalf of your St Louis Cooling sales near O’Fallon, we have many reasons to further explore their impact on the environment and energy efficiency, as well as ozone damage, etc, based on compressor choices and options available in the cooling industry.

“While natural refrigerants are already a reality in commercial refrigeration, the home appliance industry has lagged behind in adoption.”  We have already explored oil free compressors, now the natural ones are up next for discussion. The United States has lagged behind Asia, Europe and Latin America in providing consumers with natural refrigerant options, according to our research on behalf of your St Louis Cooling Sales and Service near O’Fallon MO. “This is starting to change as end users, particularly in states with strict energy regulations and high levels of environmental awareness, are starting to demand natural refrigeration solutions.”

How does the EPA play a role here in the United States? “There is also increasing pressure from the Environmental Protection Agency (EPA) and the Department of Energy (DOE) on manufacturers to find refrigeration solutions that do not depend on fluorinated gases (F-gases).” Another encountered source, The Association of Home Appliance Manufacturers (AHAM), recently published an open letter announcing intentions to phase out the R134a refrigerant by 2024 while the EPA announced that a ban on this refrigerant could happen as early as 2021. R290 will be the natural refrigerant used in cooling with many compressors in St Louis MO near O’Fallon and it has zero ozone depletion potential so has much gain.

Different Style Ice Machine Compressors

Different Style Ice Machine Compressors

compressorOur complete, in-depth look at commercial ice machines on behalf of your heating and cooling experts in St Louis who also sell, service and install commercial refrigeration of all varieties is rounding the corner today into the topic of compressor types.  In previous posts on this subject near Wentzville MO, we discussed both ice machine configurations as well as ice types.  Those are definitely the first two categories to consider before purchasing your next ice machine from your St Louis MO Heating and Cooling Installation.  The compressor type is another factor about which to be educated.

“Once you’ve decided what type of machine and ice you want, the next important consideration to make is whether you want an air-cooled, water-cooled, or remote compressor.”  Air Cooled ice machines are the most cost effective typically.  They don’t involve any extra water costs.  Many are also considered Energy Star Compliant as a result of the above fact.  Keep the following in mind, however, before purchasing this style compressor in your next commercial ice machine near Wentzville MO, “Air cooled condensers do need at least 6″ of clearance around air intake and discharge areas…”

A water cooled ice machine is a better choice than an air cooled model only if the following is true (according to our research done on behalf of your St Louis Heating Repair near Wentzville MO).  The ice machine would be installed where ambient air temperatures are greater than 80 degrees Fahrenheit, the ice machine would be installed around contaminated air, like grease filled air or the ice machine would be installed in an area of poor circulation.  Water consumption will be higher, driving up the cost of operating your commercial ice machine.  However, when the above condition, or conditions are true regarding the air involved, then you may need to consider the water cooled machine as being necessary.

Types of Ice in Your Ice Machines

Types of Ice in Your Ice Machines

frozen drinksWe represent a heating and cooling service company near Sunset Hills in our informative writing excerpts.  We, today, continue a piece surrounding the commercial ice machines available for sale today.  In the event you are shopping for one to complete your list of required restaurant equipment needs in St Louis, we want to help you make sound and educated purchases.  Previously, we covered the variety of ice machine configurations.  Most commercial settings will require a modular ice machine, though health care and small bar settings might use either counter top or undercounter configurations for their ice machine needs.

You will want to understand, also, according to your commercial heating and cooling near Sunset Hills MO, the types of ice available to you.  There is cubed ice, for starters.  This is the most common and melts slowest so therefore, can result in less ice consumed.  This can be made by your ice machine in three different possible sizes of full, regular or half.  Then, there is nugget ice.  Softer and easier to chew, but still slow to melt, this style ice is used most oftentimes in the healthcare setting, according to your Heating and Cooling Installation Company in St Louis near Sunset Hills.  The third common ice style is called flake ice.  These cool quickly and can be molded into any shape.  This can be great for seafood and meat displays, deli cases and salad bars.  Also used for snow cones and to make mixed drinks that are blended, so bars may like this style ice machine as well.

We will continue this lengthy, yet informative series on commercial ice machines on behalf of your St Louis Heating Service near Sunset Hills and begin the next series of posts on types of compressors to educate yourself on prior to purchasing your next commercial ice machine in St Louis MO.

Warehouse Refrigeration Standards

Warehouse Refrigeration Standards

American Services HVAC services in St. Louis knows that refrigeration in warehouse setting pose a number of challenges. Aside from the technical aspects of HVAC Refrigeration system design for warehouses, there are many standards which regulate the scope and applications of warehouse refrigeration systems. Understanding these standards are pivotal in maintaining productivity.

The intent of warehouse HVAC Refrigeration standards is to regulate storage space rather than quick chilling space or process equipment. It is important to recognize that there is often a variety for space types and equipment connected to a particular suction group in a refrigerated warehouse. This makes it difficult to identify compressor plant equipment that serve the storage space only. For the purpose of the standards, the compressor plant requirements apply when 80 percent or more of the design load connected to the suction group is to serve storage space, where a suction group is referred to one or more compressors that are connected to one or more refrigeration loads, that operate at a common suction pressure.

These standards apply to both coolers and freezers. Coolers are defined as refrigerated spaces cooled between 32 and 55 degrees where Freezers are defined as a refrigerated space cooled below 32 degrees. The Building Energy Efficiency Standards do not apply to walk-in refrigerators or freezers they are covered by the Appliance Efficiency Regulations. A walk-in refrigerator or freezer is defined as a refrigerated space of less than 3,000 square feet. The Standards are solely intended for storage space.

With a basic knowledge of your facility and the requirements for each set of standards, you are more capable of ensuring your operation meets the requirements set forth.

The Nuts and Bolts of Industrial Cooling Chillers

The Nuts and Bolts of Industrial Cooling Chillers


industrial chillers in MOAmerican Services industrial cooling equipment repair in Saint Louis knows that whether you are in the plastics, metal working, chemical processing or other industry you may currently utilize or might be seeking to integrate industrial cooling chillers into your operation. 

Perhaps you are an expert or just wanting to get some basic information on chillers.  Either way, new technology with chillers is quite exciting and can assist in increasing production of your industry.

Chillers for industrial applications will typically be centralized, where one chiller may serve multiple cooling needs.  Some industries do require the chillers to be decentralized, giving each application its own cooling capability.  However, it is not uncommon to see a combination of systems.

The key component in industrial cooling chillers is the vapor compression chiller technology.  There are four basic types of compressors used in vapor compression chillers; reciprocating compression, scroll compression, screw-driven compression, and centrifugal compression.  Depending on your application, these compressors can be powered by electric motors, steam, or gas turbines.

Most industrial chillers are closed-loop systems.  These type of systems will circulate coolant or clean water with additives at a constant temperature and pressure all within pipes and sealed tanks.  The water flows from the chiller to the application and then back to the chiller.  Some industries will utilize open-loop systems.  In this type of system, there is an open tank where the liquid is constantly circulating.  Liquid is pulled from the tank and pumped through the system.  A thermostat adjusts the temperature of the liquid cycling process to ensure the tank temperature is set properly.

When selecting a system it is essential to consult with a professional that can properly assess your application and make recommendations based upon your operation.
