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.

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.

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%.

From Salt to Freon in Refrigeration

From Salt to Freon in Refrigeration

refrigerationWhen it comes to refrigeration, there is vast history in its making and it, like many other modern day technologies, hasn’t been around forever, nor has it always provided the same level of efficiency and function.  As we learned previously, salt was an ancient form of meat preservation and actually worked.  “Salting food was a common preservation method before the invention of refrigerators.” Bacteria cannot survive in salt, so rubbing dry salt on food or covering it in a salt solution called brine can help keep meat and other foods from spoiling. The actual earliest form of refrigeration was seen by the few people who had the advantage of an icehouse to cool their food to preserve it.

In the early 30’s, Freon came to be.  According to our research on behalf of your St Louis Refrigeration Repair near Clayton MO, the biggest concerns surrounding Freon were environmental.  There was definitely proof that it was not the best thing for our environment and so scientists worked to modify and help minimize the potential damaging effects.  As a result, mandates and chemical make-up of Freon has evolved over the years.

Today, just about all American households and businesses have a refrigerator. It saves a ton of time in preserving foods, making it much more practical and convenient for our modern day, demanding lifestyles.  The food being preserved, according to your St Louis Refrigeration Maintenance near Clayton, is allowed to remain safe and edible for much longer periods of time as well.  “Because of the number of refrigerators used in homes, businesses, and transporting food and supplies, there is a significant need for trained professionals who can repair and maintain this equipment. HVAC technicians are well-versed in refrigeration technologies as it cools and dehumidifies. When these systems are in need of repair, they require knowledge in the theory behind the systems and knowledge in how the equipment runs to be able to fix it.”

 

Bottoming Cycles and Recycling in HVAC

Bottoming Cycles and Recycling in HVAC

HVACAs a follow-up to our previous posts regarding St Louis HVAC service near Overland and some of the heat recycling methods out there, we are going into more detail about bottoming cycles.  “Bottoming cycles are mostly used in industrial facilities in the chemical, paper, and primary metals sectors, as these industries often have high-temperature waste streams that are favorable for waste heat recovery. As much as 20-50 percent of the energy consumed in some industrial processes is ultimately lost through waste heat contained in streams of hot exhaust gas and liquids and through heat conduction, convection, and radiation from hot equipment surfaces and heated product streams.”

The goal, so to speak, is a simple one that applies to only some processes as others may not be safe enough when it comes to the waste they produce.   The overall energy efficiency of some industrial processes can be improved by capturing and reusing the waste heat, however, in situations where it makes sense from a safety and function point of view.  In our recent research on behalf of your St Louis HVAC installation near Overland MO, we discovered many facts surrounding the process to share here and in posts to follow.

“In some cases, such as industrial furnaces, efficiency improvements resulting from waste heat recovery can improve energy efficiency 10-50 percent. A study by the U.S. Department of Energy’s (DOE) Energy Efficiency and Renewable Energy office (EERE) identified research, development, and demonstration efforts to expand waste heat recovery practices in the U.S. industrial sector.”  In the aforementioned study, the waste streams analyzed showed that roughly 60 percent of unrecovered waste heat is low quality (i.e., temperatures below 450°F).  We will explore more regarding what this means as we further our research into heat recycling and HVAC in St Louis.

Bottoming Cycles in HVAC

Bottoming Cycles in HVAC

recycled HVACWe are moving along the HVAC train and looking for new and exciting information to share with you from your HVAC installation and service in St Louis near Chesterfield MO.  We found some interesting info on CHP or Combined heat and power systems and thought we ought to pass it alone.

“Combined heat and power (CHP) systems are being used by a wide range of applications to reduce the overall energy intensity of industrial systems. There are two types of CHP, depending on whether the system produces power first, then heat, or heat first, then power.”  According to your HVAC sales in St Louis, the topping cycles involve hot exhaust of an electricity generator.  Something like a natural gas turbine or reciprocating engine, is used to provide process heat, hot water, or space heating for the site. “According to preliminary 2015 data, topping cycles are used by 89 percent of total CHP capacity.” In bottoming cycles, also referred to as waste heat to power, wasted heat from a furnace or other high-temperature industrial processes is recovered and used for power production, which is also found to be noteworthy in our recent research as this is a form of energy recycling.

According to our HVAC sales St Louis near Chesterfield and the research recently done online, the bottoming cycles typically use waste heat boilers or steam turbine systems. “Ongoing research, development, and deployment efforts are focused on these systems as a way to reduce wasted heat and increase industrial energy efficiency.”  From an HVAC perspective, bottoming cycles are most times being applied in industrial facilities in chemical, paper, and primary metals sectors since these particular places often have high temp waste streams that are best dealt with using waste heat recovery.  All of this and more can be discussed as it applies to St Louis HVAC near Chesterfield and we will attempt to elaborate in future posts on this very subject.

Overheating Deaths

Overheating Deaths

fanLooking further into the effects of natural disasters on HVAC systems on behalf of your St Louis Heating and Cooling Repair near Clayton MO, we found some interesting information regarding the Great East Japan Earthquake and the tsunami that resulted in March of 2011.  “The aftermath of the Great East Japan Earthquake and resulting tsunami of 11 March 2011 provided researchers an unexpected opportunity to explore the relationship between air conditioning and risk of heat-related death.” According to our research on behalf of St Louis Heating Sales near Clayton, there have been many prior studies that reported associations between access to and/or use of air conditioning and lower mortality risk. However, the new results, published in Environmental Health Perspectives online, suggest that reducing the use of AC during summer heat may not necessarily have adverse consequences for human health, depending on the age and existing health of the people being considered.

The following was reported, “The 2011 earthquake and tsunami severely damaged the Fukushima Daiichi Nuclear Power Plant and caused severe electrical shortages in the Tokyo metropolitan area. To conserve energy, the government strongly encouraged residents served by Tokyo Electric Power Company and Tohoku Electric Power Company to reduce electricity consumption by 15% from July to September of 2011.

The urgency was heightened to reduce energy consumptions although campaigns promoting energy conservation have long been a summertime fixture in Japan.   Many residents of Japan working to reduce cooling bills and energy consumption swapped AC for fans.  The end results were not troubling to their health.  Interestingly enough, heat related deaths actually decreased during this time.
