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.

Variable Speed Compressors

Variable Speed Compressors

compressorThere is a definite global need and initiative to conserve energy.  This, combined with mitigating climate impacts is and has been putting pressure on manufacturers to design new ways to continue energy efficiency measures and reduce damage to the ozone layer all at the same time.  According to the research done on behalf of your St Louis Refrigeration Sales and Service, “This pressure is driving an uber-trend of sustainability in the refrigeration industry and has led to some truly innovative solutions and breakthrough technologies, especially in the design and production of compressors.”

Variable speed compressors are just one example of the above.  They tend to be extremely flexible and provide tremendous energy efficiency. Your St Louis Refrigeration Sales and Repair know that they are designed to adapt the cooling capacity according to the refrigeration need and are capable of working in any energy grid worldwide, regardless of the voltage and/or frequency being used. Thanks to the development of an intelligent electronic inverter, variable speed compressors are possible.  They have sensors that identify the temperature inside the cabinet and send signals to the compressor to change its speed to reach the target temperature much faster. Because a variable speed compressor cools according to need, it consumes 40% less energy than a conventional compressor, thereby accomplishing the combined goal of energy efficient and highly functional in refrigeration.

Looking at these compressors from a global view, it is apparent that variable speed compressor usage is trending globally and is already well established in many developed countries that are more focused on energy efficiency than others. “For example, approximately 90% of compressors currently in use in Japan are variable speed. In 2011 there were six million variable speed compressors in use around the world; by 2018 it is estimated that number will be 23 million. This is good news for the environment and for consumers.”

 

Thermostat Determination With HVAC

Thermostat Determination With HVAC

thermostatHere, on behalf of your St Louis HVAC sales and service near Ballwin MO, we discussed the possibility of handling your own thermostat installation, assuming you may need one.  You’re your HVAC causes issues, it is important to be able to diagnose the problem to the best of your ability, then seek professional help when you come to the end of your rope.  Say you determine that it is indeed a thermostat you need for your St Louis HVAC system near St Peters.  What type of thermostat do I need?  This is a question best answered by researching.  In doing so, on behalf of your HVAC sales in St Louis MO, we found that the first step is to survey your heating and cooling systems to see what type you have (heat pump, boiler, furnace, electric baseboard).  “If you have a boiler you need to count the number of wires in the old thermostat. If you have three wires it requires a special unit.”

According to the expert articles we read from online on behalf of your St Louis HVAC sales near Ballwin MO, we know that another thing is to check the number of stages you have of heating and cooling. “This can best be done by looking inside the old thermostat. If you have more than one stage of cooling there will be y1 and y2 terminals with wires on them. If you have a two stage furnace, there will be w1 and w2 terminals with wires on them.”

You must also find out what the source of power is that is available to the unit. This can be accomplished by looking at the existing control and looking for the following, according to our research on behalf of your HVAC sales near Ballwin. “If you are replacing a digital unit, look for a C terminal. If there is not a C terminal or there is no wire attached to it, you will need a battery operated replacement unit. If there is a C terminal with a wire attached to it, You can use a system or battery powered unit. If you are replacing a mechanical thermostat, it is best to get a battery powered replacement.”

Makeup Air and Commercial Kitchens

Makeup Air and Commercial Kitchens

ventilationIn our previous post on behalf of your St Louis Restaurant Equipment Installation near University City MO, we discussed some of the options for ventilation that you may or may not want to include on your restaurant equipment list for your upcoming commercial kitchen needs.  How is it that you ought to decide upon which style and function you need in the way of ventilation?  Originally, we talked about how it is based upon your cooking style, and although this is definitely true, there are other factors that weigh in besides cooking style and mechanical needs and space of ductwork.

Self-circulating hoods and grease extractors are two things to become familiar with, according to our St Louis Restaurant Equipment Maintenance near University City MO.  “Venting to the outside can be difficult, especially if your commercial kitchen is in an older, large building, but it is necessary. Self-circulating solutions aren’t generally safe for commercial kitchens and most states won’t allow it.”  You will want to make sure you consult an engineer if this is a problem for you.

Don’t forget to consider your commercial kitchen’s layout requirements before deciding upon the best vent for your restaurant equipment needs as well.  To maximize on the abilities of your exhaust hoods you will want to keep these things in mind:  Cooking equipment is always best placed far back against a wall in your kitchen. Wall-mounted hoods traditionally work better than overhead options, according to the experts.  If you place exhaust hoods directly over cooking appliances, this will help the effectiveness of the ventilation.  Also, mounting them low will keep them very accessible also optimizing them performance.  Last, but not least, when considering ventilation options for your commercial kitchen in St Louis, research makeup air and why this is well worth the investment when supplying your commercial kitchen with all of its St Louis Restaurant Equipment near University City MO.

Oil Free Compressors Advantage

Oil Free Compressors Advantage

advantageThere exist a variety of subjects with cooling at the center.  Besides HVAC, Refrigeration is the next biggest related category and within that, we have much to research and discuss regarding compressors, more specifically still, the efficiency and ability of one compressor to the next in the St Louis Cooling Sales and Service near St Peters MO.  Oil free compressors are today’s focus.

Labeled as a breakthrough technology, oil free compressors are truly capable of revolutionizing residential refrigeration for the household market. According to facts gathered on behalf of your St Louis Cooling Repair near St Peters, “This technology, which has been available for households since 2014, expands the possibilities of appliance and kitchen design. Because it does not use oil, it is smaller and provides the manufacturer with more freedom in terms of where within the unit the compressor is installed.” This flexibility is a big factor in cooling since it not only provides appliance designers flexibility in how the equipment is configured but can also help save valuable real estate in the home kitchen where things already tend to be tight for many.

Cooing experts report that the home sector’s first oil-free compressor uses no oil due to a special surface coating and a single bearing lubricated by the refrigerant gas itself. Running on a wider range of capacity modulations instead of switching on and off, it is able to result in minimum temperature variation and better food preservation, according to all we read on behalf of your St Louis Cooling Sales near St Peters MO.  Described by professionals in the industry as compact, flexible, quiet, energy efficient and over 90% recyclable, the oil-free compressor is poised to transform home refrigeration without a doubt.

Refrigeration Continues to Gain Interest

Refrigeration Continues to Gain Interest

InterestRefrigeration has many facets of interest in the real world as the global appetite for refrigeration is growing at an unprecedented rate according to experts.  On behalf of your St Louis Refrigeration sales near Overland, we bring you some of the details to back up the facts. Not only is there increasing demand for commercial refrigeration for food storage and transportation, but the domestic refrigeration market is also booming according to the sales of area refrigeration retailers in and around St Louis MO. “In mature, saturated regions like North America, home refrigerator and freezer sales are primarily driven by replacement. In emerging markets such as the Middle East, Latin America and China, the growth is spurred by a new, more affluent middle class demanding modern appliances and improved food quality and variety.” To back this up is the fact that in India, for example, purchase of home refrigerators grew by double digits last year alone.

The rapidity with which the market continues to grow has consequences, according to much that we read on behalf of your St Louis Refrigeration Repair near Overland.  “This rapid and continued growth has serious economic and environmental consequences. With the increase of refrigeration units in use comes the corresponding increase in energy consumption and environmental impact.” We can do the math by counting the approximate 1.4 billion domestic refrigerators and freezers in use worldwide, each with an annual average consumption of 450 kWh.

If we look at this from a different angle, on behalf of your St Louis Refrigeration Maintenance near Overland MO, home refrigeration units consume 649 TWh annually all together, which is equal to the entire energy consumption of the American Midwest, including Illinois, Indiana, Michigan, Ohio and Wisconsin, for one year. And, these numbers are expected to climb, as the global appetite for refrigeration continues to increase.

HVAC Thermostat Diagnosis

HVAC Thermostat Diagnosis

thermostatIn the world of HVAC, there are many things that you may run across that require the consultation and even employment of a professional, like those available at your St Louis HVAC installation near St Peters MO.  However, sometimes, the repair may be manageable by you.  When it comes to replacing a thermostat, you may be surprised how simple this is.

We will only look at installing digital units here because there is really no benefit to installing a mechanical unit and we want to emphasize that only you can decide if this sort of maintenance is something that you can handle.  Don’t feel badly about the use of a professional when needed.  If you are having problems with your furnace or air conditioner, you can and should begin by checking the thermostat for proper operation.  Make sure you begin by shutting the power off to the furnace and/or ac unit and switch the fan from auto to on mode, according to your St Louis HVAC repair near St Peters.  At this point, if you are having furnace problems, you can disconnect the r and w terminals at the thermostat. Twist the two wires together and then turn the power back on. If the furnace comes on, the thermostat is bad and you should continue with thermostat replacement. If the furnace does not come on, the problem is not the thermostat and you would be wise to seek a professional HVAC repair company for further assistance.

If you are having ac problems, disconnect the wires from the r and y terminals and twist them together. Turn the power back on to the furnace and/or ac unit. If the system runs the thermostat is bad and should be replaced. If the ac still does not run, the problem is not the thermostat.  If you stay tuned to this blog, we will cover next, some of the questions surrounding the type of thermostat you may need when your HVAC system goes out.

Ventilation in Your Commercial Kitchen

Ventilation in Your Commercial Kitchen

ventilationAt the onset of your new restaurant opening and just before you put into use all that you have learned about how to effectively run a business, you really ought to take some time to research your commercial kitchen and it’s ventilation needs before you check the box for done.  While you should always check with official national and local fire codes, we’ve compiled a few answers for frequently asked questions to help you understand what to pay attention to when it comes to your kitchen ventilation, all of which we gathered from online research done on behalf of your Restaurant Equipment sales in St Louis near Overland MO.

You will need the right exhaust hood despite your choice in restaurant equipment. This decision has a few factors to weigh in while pondering.  A, which type of exhaust you will need based on what you will be cooking.  Also, there are two basic types.  One is for the style cooking that is heavy on grease and smoke such as grilling, broiling or frying.  Type 2 is for the heat and moisture that results in baking or steaming.  Obviously, depending upon your Restaurant Equipment in St Louis MO and the style of cooking you most often do, the hood option will vary.

Another requirement for consideration when looking at ventilation of your St Louis Restaurant Equipment near Overland MO, is the actual physical size and mounting height that should be determined based on the capture zone required.
Ventilation design and how your ducts run to the outside have a big impact on your needs as well. Ducts with longer runs that aren’t straight may require a higher exhaust rate since the air is traveling a greater distance.  When setting out to decide on ventilation for your Restaurant Equipment in St Louis, be sure to consult a professional.

Alternate Cooling Dynamics

Alternate Cooling Dynamics

alternativeDid you know that when it comes to cooling a space, there exist many different means to an end?  “Dais Analytics in Florida, in partnership with Oak Ridge National Laboratory (ORNL), is developing a new membrane-based rooftop air conditioner, which would use water as a refrigerant instead of conventional chemicals.”  We are always seeking, according to the research recently done on behalf of your St Louis Cooling Sales near O’Fallon, ways in which to function sans chemicals. Not only is this technology perfect for sweltering, humid summer nights, but it could also save 30%-50% in electrical consumption compared to today’s roof top units, not to mention work to cut out the chemicals that we are always doing our best to avoid.

“United Technologies Research Center in Connecticut is exploring electrocaloric, solid-state technology to develop a heat pump that will keep a space cool without using any chemical refrigerants. This technology is ideal for residential and small commercial buildings.” It’s small and quiet, and could result in 25% system efficiency improvement, along with possessing fewer mechanical parts.  It is much improved in the Cooling Maintenance in St Louis near O’Fallon with the likelihood of increased reliability that results in a total reduction of your chances of losing A/C in the midst of a heat wave!

One of the other goals in this movement and wave of technology is based, according to our research done on behalf of your St Louis Cooling Sales and Service near O’Fallon is to develop an energy storage system that integrates with HVAC units to reduce the overall energy requirements of A/C systems by utilizing waste-heat that would otherwise be lost in traditional systems. Integrating ground-level diverse energy storage with HVAC could reach overall energy storage efficiency of 70% and improve HVAC performance by 35%.

Green Alternative Heating

Green Alternative Heating

greenWe spent the previous post discussing the measures that one randomly selected University was taking in the way of energy efficiency with green technology.  “Green heating and cooling systems fall under two distinct categories: passive and active.” Passive systems work by maximizing nature’s ability to heat and cool without furnaces or air conditioners [source: Green Technology]. “Among other things, passive technology includes constructing homes with white or light-colored roofs that reflect the sun’s energy instead of absorbing it.” As a result, the amount of energy it takes to cool a house is less. Passive designs also use windows that can keep the heat out and cool air in.  They remind me of staying safe from a sunburn by sitting in the shade as opposed to the chemical (active ways) of sunscreen.

According to our recent research on behalf of your St Louis Heating and Cooling near O’Fallon MO, active designs use a variety of mechanical heating and cooling systems. These systems tend to run on solar power, geothermal power or other sources of green energy.  It’s a gradual one, but the increase in green-energy use, according to your St. Louis Heating Sales near O’Fallon MO, in recent years is slowly having an impact.

“For one thing, Americans saved more than $19 billion in 2008 by using various green heating and cooling systems [source: U.S. Department of Energy].”  The cost is high, though, according to your St Louis Heating installation near O’Fallon. “But these green systems are not cheap — some solar collectors cost between $30 and $80 per square foot for installation.”  There are incentive programs offered now and then by the government, but not consistent enough to really go into details here.  The next several posts will cover all of the other green heating and cooling methods we uncovered.
