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.

Induction Benefits in Your Restaurant

Induction Benefits in Your Restaurant

inductionIn the previous post here, on behalf of your Restaurant Equipment sales in St Louis, we covered the different ways in which you can cook in your commercial kitchen near Ladue.  One of the best methods of cooking when it comes to burner types is with an induction burner. Now, we want to talk about why this is the case.

Induction is more efficient.  “Because as much as 90 percent of energy used is turned into heat that cooks food, compared to less than 40 percent of gas and the 74 percent efficiency of traditional electric equipment, a commercial induction range is the most energy-efficient cooking equipment you can buy.”

Also true, and discovered in our research on behalf of your St Louis Commercial Restaurant Equipment sales near Ladue is the fact that induction cooking keeps your kitchen cool. “Because induction cookers generate heat only in the pan you’re cooking in, less ambient heat escapes into the air. Translation: your kitchen stays cooler than it would if you were using any other source of heat to cook with.”  Because of this fact about the heat distribution, induction cooking becomes safer to use as well, since the surface of the range stays relatively cool.  This is true even when it’s just been used to bring a stock pot to a boil.  Therefore, including induction cooling methods into your restaurant equipment in St Louis near Ladue, you will actually be keeping your kitchen staff safe from burns.

Also true of St Louis Restaurant Equipment near Ladue that includes induction capabilities is the following, “It offers quick response. Electronic controls let users make instant changes to pan heat levels. That precision control makes a commercial induction cooktop suitable for applications that require close control over temperatures like melting chocolate.”

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.

Induction Burners in Restaurant Equipment

Induction Burners in Restaurant Equipment

inductionWhen looking at restaurant equipment needs and sales in St Louis near St Charles, we know that there are many out there that will not be in the loop regarding different burner types and which one or ones might work best in a restaurant environment.  On behalf of your Restaurant Equipment Sales in St Louis near St Charles, we will begin with an in-depth description of induction.

“Induction cooking has been popular in European restaurant kitchens for decades, but slow to catch on in the states. Although this method does require a different way of thinking, chefs who make the leap appreciate the technology’s speed, efficiency, and safety.” How does it work when you choose induction burners for your restaurant’s commercial kitchen?

There is definite science behind the induction cooking method and it comes down to electromagnetism, which is the same type of energy that accounts for everything from visible light to microwaves and radio waves. In a commercial induction range, for example, electricity flowing through a dense copper coil inside creates a magnetic field just above the cooktop’s surface. When that field comes in contact with an induction-ready pan, which by the way is a necessity when using induction as part of your St Louis Restaurant Equipment, electrons in the pan’s metal begin to move around rapidly. The resulting friction creates the heat you cook with.  There are definite reasons why one would pursue induction burners, according to the research we have done on behalf of your St Louis Restaurant Equipment Installation near St Charles.  It’s highly energy-efficient to use induction. “Because as much as 90 percent of energy used is turned into heat that cooks food, compared to the less than 40 percent of gas and the 74 percent efficiency of traditional electric equipment, a commercial induction range is the most energy-efficient cooking equipment you can buy.”  We will go into more depth in our next post here on behalf of your Restaurant Equipment Sales and Service near St Charles MO.

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.

 

Lightening and Your Heating and Cooling

Lightening and Your Heating and Cooling

lighteningFrom your Heating and Cooling Sales in St Louis near Ballwin MO, we bring you some of the less popular subject content along with the other more exciting discussions.  Today, it is the former of the two, as we discuss disasters in the HVAC world.  “Even though, you may be keenly concerned about your uprooted trees, windows, and roofing system, after you have experienced a natural disaster, your HVAC system could also be in jeopardy. Once the natural disaster passes and your electricity is restored, it is crucial that you become familiar with the ways that a storm or hurricane could damage or destroy your HVAC system.”  We will go through specific disasters now and how they affect your system.

Lightening is the first thing we stumbled upon in our recent research on behalf of your St Louis Heating and Cooling Repair near Ballwin MO.  And the truth is, when lightening does strike, it can adversely affect your air conditioning or cooling system since this relies on electricity in the home to function properly. “When the electricity is disrupted, it could cause issues to your air conditioning system. The additional power resulting from a lightning strike could flood the circuit breaker in your home.” It could even damage electronics and appliances. There is something you could do, however, preventatively.  It is highly recommended that you install a surge protector prior to any natural disaster. This can absorb most of the electricity before it can damage anything in your home, along with your heating and cooling system in St Louis. A surge protector is also important in saving your HVAC equipment.

We will continue this conversation in the next post as we cover the ins and outs of hail and how that, along with other natural disasters can and will take its toll on your HVAC system in ways that your St Louis heating and cooling maintenance can predict and handle.

 


 

Natural Disasters in Heating and Cooling

Natural Disasters in Heating and Cooling

lighteningLooking even closer and into more detail at what happens when natural disaster strikes and your HVAC is involved, we come across information from our most recent research on behalf of your St Louis Heating Installation near Wentzville MO that we wish to share.  “When a tornado strikes, it comes with high winds, but also lightening. Hail, on the other hand, could follow a tornado or severe storm. It comes with heavy pelts that could subsequently damage your HVAC system.”  It is recommended in order to protect the fragile parts of the condenser coil, that one installs a hail cover over the air conditioning unit. Although it may not deflect everything since small debris can go through the guard, lodging in the equipment, it is better than nothing in terms of level of protection.  If something does lodge in the equipment, however, we found through our recent research, that you ought not attempt to use your AC until you have consulted an expert.

Water damage is another big deal when it comes to the aftermath of natural disaster.  In our recent studies on the subject on behalf of your St Louis Heating service near Wentzville, we also found that many people are affected by this as well.  “A storm or hurricane comes with lightening and heavy rains, causing water damage. In fact, when the storm hits an area, its slow movement could cause a significant amount of water to accumulate in your yard and around your HVAC system. Debris and grass could wash into the HVAC unit as water rises.”

In light of all possible disaster damage, it is recommended that before you experience severe weather, it would be an excellent idea to contact an HVAC contractor to inspect your outside HVAC unit. The HVAC professional would make sure that the unit is elevated to a height to keep out as much standing water as possible. Call your local Heating installation in St Louis near Wentzville for more information today.

Ice and Thermal Driven AC Technology

Ice and Thermal Driven AC Technology

iceThermally-driven air conditioning is the next new technology that we wish to discuss further on behalf of your St Louis Refrigeration Sales near South County MO.  “Chromasun, based out of North Sydney, as in Australia, makes a thermally-driven chiller that provides a low-cost alternative to conventional air-conditioning units, which are electrically driven.”

That seems like a lot to wrap your head around, but essentially these chillers make use of solar energy that, when running short, can be supplemented by natural gas and that lends itself to a greener route and also adds significant value to our discussion about renewable energy in the St Louis Refrigeration Sales world. The company mentioned above makes it own solar panels that generate a high enough temperature to drive a double-effect chiller, which it describes as its most effective system. According to our most recent research on the subject on behalf of your St Louis Refrigeration Service near South County, the company’s double-chiller system is said to provide more cooling than comparative photovoltaic systems, and eliminates electricity costs.

Another cool concept is the ice powered air conditioner. “Ice Energy, based out of Glendale, Calif., uses an ice-powered air-conditioning unit called the Ice Bear to cool buildings and in most cases, reduce a building’s total net energy consumption.”  Keeping up as best we can on the latest technology, your St Louis Refrigeration Maintenance and Sales near South County found the following information worth sharing for green HVAC and Refrigeration evidence in our neck of the woods.   “In a very abbreviated description, the Ice Bear works by freezing 450 gallons of water in a tank overnight and making that available for cooling the next day. When the Ice Bear is switched from its Ice Charging to Ice Cooling mode, it provides cooling for up to six hours. After its ice has melted, the job of cooling reverts back to the building’s conventional commercial A/C unit, which is why the Ice Bear works in conjunction with a conventional unit. The company describes the product as the first effectively loss-less energy solution.”

On-Command Hot Water Recirculator

On-Command Hot Water Recirculator

water recirculatorThe world has been leaning green for the past several years now and HVAC is no exception.  “As recently as December 2013, President Obama said that the U.S. federal government must double its reliance on renewable energy by 2020, meaning that 20 percent of its energy supplies will need to come from renewable sources. The reliance on green energy has several benefits, including the ability to decrease the ‘environmental footprint’ on the plant, according to the U.S. EPA as well as to alleviate energy security issues while spurring economic growth within the U.S.”

We set out, on behalf of your St Louis HVAC sales and installation near Kirkwood, to deliver more info on just what that means from an HVAC perspective.  We know that the green trend means plenty of changes to the HVAC industry, but just exactly what, we were not sure. “Companies in the U.S. and worldwide are involved in research to create more energy-efficient traditional systems as well as new types of systems that run off alternative energies, such as geothermal or solar.”  We found a lot of information when researching for your St Louis HVAC sales near Kirkwood, but also realized that even more improved technologies can be expected in the future as companies work toward changing this country’s reliance on fossil fuels, which in the U.S. stands at 82 percent. “Only about 9 percent of the country’s energy supplies currently make use of renewable sources, which leaves plenty of room for change in HVAC systems.”

The on-command hot water recirculator is the one product we will describe today, in the HVAC green movement.  “This product, produced by Taco, Inc., out of Cranston, Rhode Island, saves money, energy and water while delivering hot water in a timely manner.” It involves installation of the “On Command” pump that attaches to the hot and cold water lines under a kitchen or bath fixture in a home, according to our HVAC research. “When activated, it allows the cool water being drained to circulate back to the water heater through the cold water line, allowing hot water to be delivered at any time 24 hours a day.”  The energy conservation is obvious here and kicks off our series in the St Louis HVAC installation near Kirkwood on HVAC renewable energy and green movements.

Slicers and Other Small Restaurant Equipment

Slicers and Other Small Restaurant Equipment

slicerPrep tables, counters, and cutting surfaces are essential to any commercial kitchen and come in various sizes.  Today we will be looking at the different smaller components in your commercial kitchen as we bring you our newfound information on behalf of your St Louis Heating and Cooling Service near Maryland Heights MO.  We are attempting to answer some of the questions surrounding how to find what your commercial kitchen needs in the way of HVAC as well as restaurant equipment.

For starters, it is recommended that you choose preparation surfaces made of stainless steel. Stainless steel is sturdy against corrosion, resists attack from food and meat juices, and can withstand the harsh cleaning products used in commercial kitchens.  From your St Louis Heating Installation near Maryland Heights, we are passing along our recent discoveries.  When it comes to surfaces that you use for cutting, it is advised by all that we read on behalf of your Heating Repair in St Louis near Maryland Heights, that you choose either plastic or wooden cutting boards. “Plastic boards are easier to sanitize but can develop deep grooves that can hide bacteria. Wooden boards are generally tougher than plastic ones and don’t develop grooves as easily.”

Slicers are often tasked with cutting meat, cheese, or other foods with speed and precision and are another common purchase for those stocking their restaurants with equipment in St Louis MO. “If you need to purchase a slicer, consider how often you’ll need to use it. If your slicing is low volume or infrequent, a manual food slicer is a better, less expensive option. However, for larger amounts of food or foods that need to be cut to specific proportions, choose an electric slicer instead. Electric slicers are automatic, which can save you time and labor. Moreover, most electric slicers allow you to turn off the automatic function and operate the machine manually.”
