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.

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%.

Beating the Heat With Proper Maintenance

Beating the Heat With Proper Maintenance

bright sunWhen summer is upon us, most people get excited and look forward to enjoying the summer sun and beating the heat in a cool, air-conditioned building.  The downside to this pleasure, according to all that we read on behalf of your Heating and Cooling in St Louis near University City, are the summer energy bills.  Most of us all know that the dog days of summer can mean high energy consumption at an unfortunately high price.

In fact, on behalf of your St Louis Heating and Cooling Sales near University City MO, we found a few stats to fill in the gap here and help illuminate the point.  “According to the U.S. Energy Information Administration, space cooling will consume an estimated 1.28 quadrillion British thermal units across the United States in 2017—that’s equivalent to almost 39 million homes’ electricity use in a year. And that energy use adds up.”

We also found, when reading various articles on behalf of your St Louis Heating and Cooling installation near University City, that in residential buildings, space cooling alone makes up 9% of a home’s total energy consumption.  There are also things that can lessen efficiency quite drastically.  “Additionally, typical air conditioning units use fluorocarbon refrigerants as a coolant, which, if leaked, can lessen the efficiency of an AC system and negatively impact the environment.” If you properly maintain your AC unit by contacting professionals, such as your St Louis Heating and Cooling Repair near University City, you will at least improve the chances of having a very efficient system.

 

Cooling in Details

Cooling in Details

coolingExamining, for the last time this month, the heating and cooling system that you have at home or at work, we know that the evaporator plays a large role in the St Louis Cooling near Ladue.  The evaporator coil actually works similarly to a car’s radiator to produce cool air, which is then circulated through the ductwork.

Next, we come upon the condensing unit of your cooling system in St Louis near Ladue. We know from a recent article we skimmed on HVAC, that the following is true, “The condensing unit is connected to the evaporator coil. This unit is installed by HVAC contractors on the outside of your home and filled with refrigerant gas. When the refrigerant has been cooled to a liquid by heat exchange with the exterior air, the condensing unit pumps the liquid to the evaporator coil to be evaporated into a gas once more.”

Let us not overlook the refrigerant lines in a cooling system in St Louis near Ladue MO.  These specific refrigerant lines carry a refrigerant substance to the condensing unit which has been vaporized in the form of a gas.  It then gets returned in liquid form back to the evaporator coils. These “lines” are actually narrow tubes manufactured from a durable heat- and cold-resistant metal such as copper or aluminum.  Finally, we have to glance at ductwork and vents.  The ductwork is in reference to the system of ducts whose job is to transport air warmed or cooled by the system to the various areas of your home. Ducts are commonly made of lightweight aluminum.  According to your St Louis Cooling Repair near Ladue, they may also be manufactured from steel, flexible plastic, polyurethane, fiberglass, or fabric.

 

Different Components of Your Cooling System

Different Components of Your Cooling System

heat exchangerFrom the world of heating and cooling in St Louis near Wentzville, there exist many different components, all of which are designed to serve a purpose and many of which fly under the radar of our complete understanding.  We set out to change that, one element at a time and we are now looking at the refrigerant lines in your St Louis cooling near Wentzville MO. “The refrigerant lines carry a refrigerant substance to the condensing unit vaporized in the form of a gas, and return it to the evaporator coil in liquid form. These ‘lines’ are actually narrow tubes manufactured from a durable heat- and cold-resistant metal such as copper or aluminum.”

Now we arrive at the ductwork. In an HVAC system in St Louis, the ductwork refers to the system of ducts that transports air warmed or cooled by the system to the various areas of your home. These ducts are commonly made of lightweight aluminum. However, they may also be manufactured from steel, flexible plastic, polyurethane, fiberglass, or fabric.  Then we see the vents in your heating and cooling system in St Louis MO.  These are typically rectangular outlets where heat or cool air is transferred from the duct system to the actual rooms and spaces to be heated and cooled.

Elaborating more completely on the vents, we see that the metal is “Made of high- and low-temperature safe metal, similar to the lines we discussed earlier within the HVAC system.  The vents are located on or near the ceiling and are usually fronted with angled slats (“vents”). “These vents direct the treated air downward to where people are using the room. Often they may be manually controlled or even closed, to control the amount of heating or cooling and the area of the room to which it will be directed.”

 

The Scoop on Cooling Efficiency

The Scoop on Cooling Efficiency

energy efficiencyLooking even closer at heating and cooling dynamics in our recent research on behalf of your St Louis Cooling installation near Kirkwood MO, we stumbled upon rather interesting information surrounding the air conditioning and heat pump cycles.  “Air conditioners and heat pumps use the refrigerant cycle to transfer heat between an inside unit and an outside unit.”  The only way in which heat pumps differ from air conditioners is the fact that they can reverse by way of a special valve that does not exist for the AC, but does for the heat pump.

Both must operate within specified parameters that dictate a certain maximum level of energy consumption and new efficiency standards for central air conditioners took effect in 2015.  As was true with furnaces, the newer standards differed by region, having greater stringency in the South and Southwest than in the North. According to our recent research on behalf of your St Louis Cooling Repair near Kirkwood, new central air conditioners sold for installation in the South and Southwest must meet a minimum 14 SEER; for units installed in the North, the 13 SEER minimum remains unchanged. Air-source heat pumps must meet the 14 SEER minimum regardless of where they are installed. In addition, central air conditioners installed in the hot, dry Southwest must meet a minimum 12.2 EER (or 11.7 EER for larger models).  These are all numbers found online in our recent research and collected from reliable internet HVAC sources.

It is true that the cooling performance of ground source heat pumps is measured differently.  “In contrast, cooling performance of ground source heat pumps is measured by the steady state EER instead of a seasonal measure. The ENERGY STAR program’s minimum requirements for ground-source heat pumps are 21.1 EER for open-loop systems, 17.1 EER for closed-loop systems, and 16 EER for direct expansion (DX) units.”  We will pick up here later and dive deeper on your St Louis Heating sales and install’s behalf with room air conditioners.  Stay tuned to learn more about BTUs and how to decide just what your room or rooms need in order to keep cool in the hotter months.

What Kinds of Food are You Cooling?

What Kinds of Food are You Cooling?

http://www.americanservicesstlouis.com/products-and-services/refrigeration.htmlLooking closer at the cold well units in the refrigeration category of sales and service, on behalf of the St Louis Heating and Cooling repair near St Peters MO, we find the drop-in style coolers in the refrigeration category justify more discussion than we have done thus far.  There are iced units at your Heating and Cooling sales in St Louis which cool the wells by maintaining ice inside the unit itself.  There exist refrigerated unis as well.  “Inside the walls of a cold wall unit, there are tubes of refrigerant that cool the well from the inside. These are very efficient for cooling dense products, but might be too intense for more delicate foods like fresh produce.”

If you are cooling more delicate foods and produces like grocery stores will need for keeping produce cold, then you may wish to look at a forced-air systems circulate cold air over products to keep them cool.  These, according to our St Louis Heating and Cooling research recently done, operate more like a traditional refrigerator. These are best for more delicate items like fresh produce, but may have trouble keeping dense products like dressings and cheeses cool, so you can see that much of your decision on style is based on the products for which you need the cooling unit to begin with.

In terms of access of your cooling refrigerator, keep in mind that most are designed to hold food pans. “They sit flush with the counter and are accessed from the top. Others are enclosed in glass, similar to countertop refrigerators. This type of drop-in chiller is great for merchandising refrigerated foods like desserts in the bottom well, and can hold dry goods on the shelves above.”  There are also, according to our research on behalf of your St Louis Heating and Cooling near St Peters MO, pass-thru models which allow customers to reach in and serve themselves.  These will have rear access units as well, when kitchen staff are the only ones with access.  This allows for quality and inventory control.

 

Reducing Greenhouse Emissions in Cooling Changes

Reducing Greenhouse Emissions in Cooling Changes

climate changeWe can talk more, if you will, about the movement in the St Louis heating and cooling sales world, about GWP.  “GWP is a basic measure of a compound’s potential to trap heat in the atmosphere, also known as the greenhouse effect, when compared to carbon dioxide. R-410A, a widely used HFC refrigerant, has a GWP that is 2,088 greater than carbon dioxide. R-407C, another popular HFC, has a GWP of 1,774.”  In order to accommodate the atmosphere and do less damage to our ozone, it is important to find chemicals that do the least amount of destruction. According to our St Louis Heating and Cooling near Fenton, and the research and writing we do on their behalf, it is possible to continue to find refrigerants that cool with less and less damage to our atmosphere.

In global news on this subject, from your heating and cooling company in St Louis we found the following:  Later this year policy makers from 197 nations will be meeting in Dubai to finalize an agreement on how to phase down the use of HFCs in developed and developing countries and promote the use of low-GWP alternatives.

A little more than two years ago there was a release in the White House of the President’s Climate Action Plan, which is also very pertinent to this discussion.  In it was a regulatory blueprint for the production of cleaner energy, a more efficient transportation system, the promotion of energy efficient appliances and buildings, and the reduction of non-emissive greenhouse gases. The broad scope, or goal of this plan was to reduce (and still is) to reduce the greenhouse gas emissions, bringing them down to 17% less than they were in 2005, all by the year 2020.  Stay tuned for further details on how the St Louis Heating and Cooling industry near Fenton can play a role in helping this cause.

The Chemistry of Cooling

The Chemistry of Cooling

hot coldWhen looking at the cooling components of an HVAC system, we spent the last two posts diving into the actual breakdown of parts and what they do in their functioning to contribute to the cooling cause, on behalf of your St Louis Cooling Sales and Service near Hazelwood MO.  We covered the evaporator and the fan and coils therein, we also talked about the condenser and the fan it has to distribute cooling air into your space.  There is more to it and we will wrap up the other parts and functions here in the next two paragraphs on behalf of your St Louis Cooling Maintenance near Hazelwood MO.

All processes must have a starting point.  Here is how the cooling of your space will begin, “In between the evaporator and the condenser, is an expansion valve. The expansion valve has a crucial but simple job. It simply regulates the flow of the compressed refrigerant to the evaporator, for the cooling process to begin.”

Liquid changes over to gas.  Not sure if you realized there was chemistry involved in the process of heating and cooling your home, but where there is temperature change, there is typically chemistry and in this case, it comes in the form of phase change.  “Once the refrigerant is in the evaporator, the liquid changes states of matter. It changes into a gas. That’s where the next part of the cycle comes into play. The compressor is a pump that does just that. It compresses the refrigerant back into a liquid to start the process all over again.”  And, there you have it. That is the second part in a series regarding cooling your commercial, business and personal space and how it happens from start to finish, on behalf of your St Louis Cooling Installation near Hazelwood MO.

Cooling Components

Cooling Components

cooling componentsWhen it comes to cooling your space, there is some basic knowledge that will prove helpful to you in the quest of efficiency and weighing of all the options.  We set out, on behalf of your St Louis Heating and Cooling service near Bridgeton in order to answer some of the most common questions with mostly knowledge gap filling.

Let’s start with Air Conditioning and the cooling of your commercial, business or personal space.  This is best understood by looking first at the individual components involved in the cooling process to begin with.  There are four main components in any air conditioning unit. Each plays a significant role in cooling and maintaining the temperature in your home or office space.

The first component in your cooling system from St Louis is the evaporator.  The evaporator is fed liquid refrigerant.  The evaporator and the refrigeration coils, or cooling coils are synonymous.  The refrigerant is the liquid substance that is found in the evaporator and is typically the key ingredient for cooling the unit.  The evaporator has coils and also a fan for cooling your space.  This distributes the cool air away from the evaporator and out into the space.  The condenser is next in the cooling process according to our research done on behalf of your St Louis Cooling Repair near Bridgeton MO.  “The condenser is also referred to as the hot coils. The condenser is in charge of facilitating the heat transfer, from inside the home to the outside. There is a fan associated with this part also, similar to the evaporator’s job.”  We will move on to more parts in the next post here regarding cooling your space in St Louis.
