HVAC Noises

HVAC Noises

noisesNoises can be defined in a multitude of different ways despite the source of the noise.  In general, we can categorize any noise as expected or unexpected.  In the HVAC world, according to your St Louis MO HVAC install and repair, we can break these noises down into a lot of different areas and not all of it is unusual or of concern.  “No matter the age or price of your HVAC unit, it’s going to make noise.” That’s right, you may have become immune to the low hum that your HVAC unit emits, but it is important to note anytime there are new, unsettling noises and sounds happening.

Of course, not all noises suggest that you’re staring down an impending road of disaster, however most St Louis HVAC systems near O’Fallon MO, make noises that signal it’s time for maintenance or repair. Below are some examples of those sounds and potential causes, as well as a few tips for eliminating said noises, according to your St Louis HVAC sales near O’Fallon.

Thumping, clanking or banging:  “Other than the cheerful, big-eyed rabbit in Bambi, thumping is usually an unpleasant and ominous sound. So, if you’re hearing banging, clanking or thumping, that may be a sign of trouble brewing.  If any of these bothersome sounds are coming directly from your HVAC system, this could mean there’s an issue with your HVAC’s blower assembly. We suggest turning off your HVAC system before the issue worsens, and then calling a technician to inspect the problem.”  Popping:  Popping sounds when you turn your system on and off you can breathe a sigh of relief. The popping sound is due to your metal ductwork expanding and isn’t a problem whatsoever, according to your St Louis HVAC repair near O’Fallon MO., For elimination of the sound, insulation such as foam or rubber can help limit the noise. Other sounds will be covered in posts to follow on behalf of your St Louis HVAC installation and repair.

The Smaller Restaurant Equipment Needs

professional griddleAs a rebound from a previous writing regarding St Louis Restaurant Equipment near Overland MO, we want to talk about a few other pieces of restaurant equipment that we find rather important to the operation of your new commercial kitchen near Overland MO.  “When it comes to serving beverages, ice machines are just as crucial as soda fountains. Ice machines create ice and then dispense it into an ice bin or soda fountain. While ice is necessary for serving soda and iced water, you can also use ice machines to create blended drinks like smoothies, margaritas, and alcoholic slushies.”

Another interesting, yet less discussed piece of restaurant equipment in St Louis near Overland MO is the salamander broiler.  These pieces are valuable types of equipment for pizzerias, sandwich shops, and bakeries as they allow you to finish off your dishes before serving them to your customers. “Salamanders brown the top of your dishes and melt cheese on top of your casseroles and sandwiches to entice your customers. Some of these products also attach to your range or directly to your walls, so they don’t take up valuable countertop space.”

Let’s not overlook griddles as added elements to your commercial kitchen and part of our focus on behalf of your St Louis Restaurant Equipment near Overland.  Griddles are totally ideal pieces of equipment in cooking so many different types of food.  Burgers, breakfast foods, and grilled sandwiches are all top picks for a commercial kitchen griddle.

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.”

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.

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.

History of Refrigeration

History of Refrigeration

refrigerationThe history of refrigeration is one topic we have been meaning to explore for a while now, and so, on behalf of your St Louis Refrigeration Repair and Sales near O’Fallon MO, we will start discussing that very subject today.  There have been many changes in the way refrigeration works over time.  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. “Some people had the advantage of an icehouse to cool their food to preserve it, which was the earliest form of a refrigerator.”  According to our efforts in research on behalf of St Louis Refrigeration sales near O’Fallon, we know that GE came up with the first refrigeration that not all people could necessarily take advantage of due to cost.

“After General Electric produced the first electric refrigerator in 1911, the wealthiest Americans could afford the luxury of having this new invention in their homes. Other people used an icebox to preserve their food.” An ice box was a costly alternative, according to Refrigeration sales and service in St Louis, because so much water had to be used and frozen. After freezing it, the ice had to be cut, stored and finally, delivered.  In the 1930’s is when Freon was first put to use inside refrigeration.

Progressing down the timeline on behalf of your Refrigeration sales in St Louis near O’Fallon, we find that after WWII, refrigerators were produced in mass quantities, making them affordable and widely available in the US. They popped up with new features like automatic defrosting and icemakers. “Combination refrigerator and freezer units were immensely popular. Throughout the 1970s, 1980s and into the 1990s, environmental concerns over the use of Freon were debated and studied. Because of its estimated effect on the environment, the government put tight restrictions on the use of Freon in refrigeration equipment.”
