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.

HVAC Basics Near O’Fallon MO

basicsOk, so, we write on behalf of your HVAC specialists at American Services in Earth City MO and that means that we are here to cover hot topics of interest that surround this and other pertinent subjects.  Today, in sharing information regarding HVAC install near O Fallon, we have decided to step back and examine some of the basics that many beginners to home and commercial heating and cooling may be unaware.

It can, after all, be a bit complicated.  On behalf of American Services HVAC service and sales, we want to make it seem simple.  Let us begin with types of systems, shall we?  “Central Heating and Cooling Systems produce warm or cool air in one central area and distribute it throughout your home. There are many types of systems that work as central systems, from Traditional Split Systems (having both indoor and outdoor components) to Packaged Product Systems (having one combined outdoor component for heating and cooling). Packaged products include dual fuel systems and all electric packaged options.”  This research was done online with several HVAC experts used to site information and sources.

Products that involve the above mentioned central systems are sold by American Service HVAC sales professionals and are as follows:  heat pumps, air conditioners, gas and oil furnaces, fan coils, evaporator coils, and controls and thermostats.  If you are trying to heat or cool specific rooms alone, then ductless systems are also viable options as they will take the ductwork out and are flexible systems that operate very quietly and can be installed almost anywhere.  There are further options and much more information to share coming up in the following posts on behalf of your HVAC specialists at American Services near O’Fallon MO.

 

Energy Star Ratings and Your Commercial Refrigeration Equipment

Energy Star Ratings and Your Commercial Refrigeration Equipment

Ecofriendly On ChalkboardIt’s no surprise that your Overland area commercial refrigeration units such as ice machines and freezers have very high energy costs.  For this reason alone, many users will look for a unit with an Energy Star rating as they replace old, out dated equipment.  Choosing Energy Star rated units will not only save you money, but these units also help the environment thanks to factors like water savings.  Here are few examples of how an energy star ice machine and refrigeration unit can save you money!

A typical Energy Star rated ice machine is 15 percent more energy efficient and saves about 10 percent in water.  This equates to about $130 in electricity and $18 in water savings on a yearly basis.  Other ways to help with your ice machine efficiency include shifting your ice production to the nighttime off-peak houses, purchasing a larger and more efficient machine, and avoiding water-cooled machines (water-cooled ice machines do not qualify for Energy Star ratings.)

A typical Energy Star qualified commercial reach-in style refrigerator or freezer can save you about 30% in energy.  This equates to about $55 per year in electricity savings for every solid door refrigerator, $70 per year in electricity savings for every glass door refrigerator, $175 per year in electricity savings for every solid door freezer, and $325 per year in electricity savings for every glass door freezer.  Other ways to save energy when using reach-in refrigerator units include turning off the door heaters, cleaning the coils, setting the defrost timers, and replacing worn gaskets.

As you can see, choosing to replace your old ice machines and refrigeration units with those that carry the Energy Star distinction can save you significant money on future energy bills.  To get more information on how Energy Star units can save your business money, contact the team at American Services for full details today!

 

 

11 Common HVAC Issues – Part 2

11 Common HVAC Issues – Part 2

Two AC techniciansWelcome back to our two part series on 11 of the most common HVAC issues.  Today, the American Services heating and cooling team near Fairview Heights will give you the final six issues of this series.  Let’s get started!

  • Thermostat – Everything starts with a good, working thermostat.  This is because this little device tells your system what to do and when.  Before calling in for service be sure your thermostat is on and in working order.
  • Drain Lines – The major issue with drain lines happens when they become filled with dirt or algae.  This will cause water to leak and can lead to water damage.  Regular maintenance can help you avoid this issue completely.
  • Refrigerant Leak – Refrigerant leaks happen.  Many times your technician can recharge your unit with new coolant and you are up and running.  If the leak happens to be in the condenser or evaporator, you will need to have a larger repair.
  • Compressor – Your compressor’s health is directly related to your unit being properly charged with the right amount of refrigeration.  Not enough will lead to overheating and too little will cause liquid slugging.  Make sure your unit’s charge is being checked during regular maintenance.
  • Condensor Coil – Since your condenser coils are exposed to the outdoor elements it is necessary to clean them often to avoid dirt and grime build-up.
  • Evaporator Coil – To avoid your evaporator coil from cracking, consult your owner’s manual for a suggested cleaning schedule.

As you can see, there are a number of issues that can cause problems with your HVAC unit, but many can be avoided with regular maintenance and a little care.  In fact, regular maintenance and care can save you time, money, and a lot of down time.  Make sure your commercial HVAC equipment is up to par by contacting the American Services team now!

Ice Machine Maintenance Tips

Ice Machine Maintenance Tips

IceKeeping your ice machine in good shape is imperative to your production of clean, fresh ice for your customers.  Don’t make the mistake that so many ice machine owners do by not taking some time to maintain your machine.  Here are a few tips to help you get started when looking to keep your ice machine properly maintained.

  • Keep your ice cooler clean by simply cleaning all of the components according to your manufacturer specifications.  This can usually be done every other week and will keep your ice cubes uniform in size and smelling fresh.
  • While doing your routine cleaning, watch for brown slime.  This icky substance grows when your machine comes in contact with certain types of yeast.  You will need to remove any evidence of this pest via your manufacturer’s cleaning recommendations.
  • Think about the location of your ice machine and how the temperature could be affecting how efficiently it runs.  It isn’t always possible to move an ice machine, but if you are able to keep it in a cooler location it will run less often and use less energy.
  • As a part of your cleaning ritual, be sure to take a look at the condition of your condenser coils.  Your machine’s condenser coils greatly determine the temperature of your unit and will cause slow production if dirty.
  • Do a visual inspection of your ice machine and listen for any strange noises.  A simple weekly check can help you identify issues early and this will help you save money if a repair is needed.

Common Cooling Equipment Failures

Common Cooling Equipment Failures

Heating Air Conditioning TechnicianAccording to Energy.gov, there are some common areas that commonly cause air conditioning units to fail.  These five areas include refrigerant leaks, inadequate maintenance, electric control failure, sensor problems, and drainage issues.  Today, we will explore all of these areas and give tips on how to handle them.

Refrigerant Leaks – Refrigerant leaks can not be repaired by the consumer and require proper handling, as refrigerant is a chemical that is harmful to the environment.  If you are experiencing performance issues and suspect a refrigerant leak, call a professional to fix the problem and charge the system properly.

Inadequate Maintenance – It is vital to perform the proper maintenance on your air conditioning equipment.  Failing to change your filters and having dirty coils will cause your compressor and fans to prematurely need attention.

Electric Control Failure – If your unit is oversized, you may experience a number of on/off cycles that is higher than normal.  This can cause corrosion of wires and terminals and thus bad electrical connections and contacts.  Have your service professional check for this issue during routine maintenance stops.

Sensor Problems – If your unit begins cycling constantly or erratically, you may have a bad sensor.  This can happen if it is knocked out of place.  Call your HVAC tech to have it re-positioned.

Drainage Problems – In humid conditions, your unit will need to drain properly and in order to do so, will need a clear condensate drain.  This is something you can check and rectify on your own.

Don’t delay giving attention to any of these common issues!  Contact the Sunset Hills area industrial cooling equipment experts at American Services to schedule an appointment today!
