Choosing an Industrial Cooling System

Choosing an Industrial Cooling System

industrial cooling in MOWhen it comes to industrial cooling in Saint Louis, American Services knows business owners do have some options.  The type of system you choose depends on the size of the area your are trying to cool, the interior building configuration, the location and other specifics that may be pertinent to your specific space.  

Probably one of the most common systems is referred to as a “split system.”  This sort of implementation is what you would typically find in a residential or small business facility.  The split system has an indoor air handling unit and a condensing unit on the outside.  This type of system has the highest energy rating, but may not work for all implementations.  The split system is also only used for cooling, so an additional heating system solution would be required.  A packaged system is similar to the split system in function, but of course all of the components are contained in one unit, as the name implies.

Another option is a chilled water system, which utilizes coils with liquid kept at a cold temperature.  This cooling of the water takes a separate cooling plant, which adds complexity and potential costs, but can work in some scenarios.  Once again, depending on the space, separate window air conditioning units can be used in certain applications.  Keep in mind that all these options require a separate heating solution 

So what is the best system to use?  The question once again depends on the space you are trying to cool.  Split systems remain a popular choice and can be supplemented with fans, individual units, smart controls and other add ons that can be adapted to the situation.  All of the aforementioned systems have their pros and cons so it is best to call in a professional who can analyze your individual space and the occupants to determine what is best.  Make sure you ask for the energy rating on the systems, warranties and any cost saving measures that can be implemented now or in the future.  That way you can start off with the right system and one that will be there for as long as you need it.

 

Radiant Cooling for Office Buildings

Radiant Cooling for Office Buildings

radiant cooling service in MOAmerican Services heating and cooling service in Saint Louis knows that most radiant cooling systems are based on aluminum panels that are extended from the ceiling through which cooled water is circulated.

In order for this system to effectively cool the office area, panels must be kept at a temperature near the dew point within the office building and the interior space must be dehumidified.  Condensation will occur in humid climates where radiant cooling systems are utilized, even when there are brief periods of exposure to the outside air within the office space. An auxiliary air conditioner may be needed to keep the humidity level low enough.

Where the climate is arid, such as in the southwest, these radiant cooling systems are advantageous particularly in the ceilings of adobe buildings where the inside air can be maintained at a steady cool temperature.

Offices built on concrete slabs are also considered some of the best candidates for radiant cooling, using the same principal as ceiling systems with chilled water systems in the floor, as well as radiant heating systems.  This option is a great choice particularly with office spaces that have existing radiant floor systems.  Humidity continues to be a concern with radiant floor cooling systems, particularly on floors that have carpet coverings instead of the preferred choice for radiant cooling systems-which is ceramic tile.  Condensation is common in areas with heavy carpet, which also limits the temperature at which the floor can be lowered to.

These systems can be very cost effective even when utilized with auxiliary cooling systems which can be used at off peak hours, reducing overall electricity demand for the business.

Industrial Portable Cooling Systems

Industrial Portable Cooling Systems

industrial cooling systems in MOAmerican Services HVAC heating and  cooling installation  in St. Louis knows that with energy costs continuing to rise, now is the perfect time to start looking for alternative cooling methods to cool your plant this summer. Instead of relying solely industrial air conditioning systems which need to run constantly, you will find other types of cost effective solutions available, which can actually help lower your overall energy costs.

One option you can explore is installing industrial high pressure water systems, which use water vapor to providing a cooling effect. Some models can even lower surrounding air temperatures by as much as twenty degrees without the use of any other type of cooling.

The costs to operate different types of alternative industrial air conditioners can be lower than one might expect.  For instance, one option is a 24-inch fan has an operational cost of $0.055 per hour with a CFM of 6,920 and a 100 foot throw. There are certainly other energy efficient cooling products available as well, or you can have a custom system just for your facility.

Protect your employees, processes and equipment from their hottest environments with portable air conditioner solutions. Portable AC units help reduce the risk of heat exhaustion and increase your employee morale, leading to improved manufacturing quality and productivity. Spot cooling units prevent product defects by eliminating warping and condensation due to excess heat and humidity. Portable cooling units are known to reduce processing time by up to 94% for most heat related production processes.

According to one expert in the industry, “We have a very hot warehouse in the summertime and have a number of applications for the portable air conditioner system that has proven successful for us for the last two years and we are looking to add several more units to our warehouse facility.”

Industrial Cooling Systems

Industrial Cooling Systems

industrial cooling systems repair MOCooling systems such as industrial chillers designed for large commercial buildings must depend on either air flow, or a liquid like water as a distribution medium.

The cooled air is then circulated throughout the building through air ducts.  When water is utilized in industrial equipment for cooling, the chilled water is distributed through pipes. These are the very most common types of commercial air conditioning systems for large commercial buildings because it’s more economical.  Water has a higher heat capacity and the pipes take up far less space than the huge air ducts.  Chilled water is much more flexible to be utilized for zone control as well.

Chilled water will cool the air in the work space by being used by a distribution medium.  Industrial chillers work through air handling units or fan coils.  Usually air handlers are found in large commercial buildings, hospitals, and other oversized spaces.  In smaller commercial spaces such as small hotels, fan coil units are usually found. These units are usually controlled by thermostats.

In water chilling systems cooling towers and chillers comprise the commercial cooling system. Chilled water distribution systems utilize the same piping system as hot water systems use.  These systems could also supply heat.

There are 2 pipe and 4 pipe systems in chilled water air handlers and fan coils used to cool.  In a 2 pipe system there is only one water loop and one return pipe for each handler.  The commercial building can be in what’s called “switch over dates” when the chiller is shut down and the industrial boiler is started up.  The disadvantage to the 2 pipe system is that if the weather suddenly becomes unseasonable, it is not very likely that the cooling system can be suddenly switched back on.

A 4 pipe system on the other hand, uses 2 different water loops, one for heat and one for cooling.  This allows for simultaneous heating and cooling in separate parts of the building.  Consequently, a switch over is not necessary.  Of course 4 pipe systems are a bit more costly due to more expensive coils, controls and the extra water loop.

Types of Commercial Heating Options

Types of Commercial Heating Options

commercial heating repair in MOAmerican Services heating systems installation in Missouri knows that installation of commercial heating systems using sustainable resources are a viable option that should be considered. These systems employ energy sources such as solar and geothermal power, leaving no footprint on our environment.

Heating, ventilating, and air-conditioning (HVAC) these systems are not only good for the environment, but over time they will perform more efficiently, generating energy cost savings and decreasing the carbon footprint that “traditional”options such as oil and gas leave behind.  Because of the relatively high initial installation costs, this type of commercial heating system is often reserved for the larger facilities.  Fortunately these costs are becoming more affordable as tax breaks and government incentive programs become more prevalent.

Oil or Gas Steam Heating Methods

Choosing an oil or petroleum steam powered commercial HVAC system, while definitely not the most efficient, is one of the oldest methods of commercial heating installations. The oil or gas is used to boil, manufacture and subsequently pass steam through the pipes-generally considered one of the least efficient processes, and at the same time, most harmful to the environment. Steam heating methods take longer than most systems to circulate heat because of the delay between the boiler being fired up, and the heat finally circulating thru a network of pipes, ending up in the radiator unit.

Gas or Oil Water Systems

An additional method for heating commercial property is using a water-driven HVAC system. Similar to steam heating in overall concept, the water heating method uses a boiler to heat water, which is then subsequently passed through a pipe network to radiators positioned throughout the facility. These water heating systems are some of the least productive heating methods and also less than ideal from an efficiency perspective. One reason for this is that you have to clear the air in the system each time the heat is engaged, causing delays in heating which results in inefficiencies.

Heat Pump Alternatives

Implementing a heat pump commercial heating alternative is the most favorable commercial heating option and is an efficient means of heating a building. This process is similar to the technology used in refrigerators, essentially extracting heat from cold. Because these types of systems do not require a fuel source (gas or oil) to function, they are very cost effective systems.

Radiator Heating Systems

Radiator Heating Systems

heating installation in MOAmerican Services commercial heating service near Webster Groves knows that there are two commonly used types of radiator systems for heating commercial installations; steam systems and hot water systems, or possibly a combination of the two.  The type used in your workplace may vary based on needs, structure size and materials available when the structure was built. Construction methods and practices varied greatly over the years. Regional building differences may also play a role in what type of system you have.

Steam

Steam radiator systems use a boiler to boil water to create steam, which in turn moves through a series of piping without the need for pumps.  One of the problems with this systems is you must wait for the steam to warm back up after shutting down.  This is considered an inefficient method.  Steam generally moves around the heating system at pressures of around 1 lb. per square foot, allowing radiator temperatures to reach up to 215 degrees F.

Water

Hot water heating systems heat water in a boiler before pumping the water around the system to heat radiators within a building. Hot water heating systems are commonly used in newer built commercial installations and residential applications and the water temperature in the system is usually limited to 180 degrees.

Formula

If you’re interested in calculating the temperature of each radiator within a heating system, the equivalent direct radiation is multiplied by the amount of heat produced by a boiler per hour. The EDR is the square footage of the radiators within a home, while the heat produced by a boiler is measured in British thermal units. Steam boilers produce around 240 BTUs and hot water boilers produce about 170 BTU’s.

Electrical HVAC Power Consumption

Electrical HVAC Power Consumption

HVAC Services in MissouriAs computer technology has evolved, so has the density of the power and the associated heat gain related with new computer equipment. Computer server racks that once were nearly empty now are filled and they put a great deal of strain on facilities’ cooling systems.

Tracking electrical power consumption can help technicians anticipate when it is time to introduce cooling to a particular space.  Many times the backup cooling unit becomes the added capacity, and professional technicians add temporary cooling to ensure redundant cooling until the installation of a permanent solution.

This situation is commonly encountered and manifests itself when the base building HVAC system is used to cool space that has been dedicated to the placement of computer equipment. Most generally the space was originally a small data room, but with the growth of technology has become a large server and data storage farm.

As a result mechanical systems struggle to keep up and maintain efficient operations 24/7.  At this point managers might arrange for the installation of a ‘temporary portable air conditioning’ that will reject heat generated by the servers into the buildings return air duct. This will give facilities maintenance an opportunity to design and implement a more permanent cooling solution.

Whenever facilities managers can integrate server expansion with increased cooling capacity, the ideal solution is in-rack or above-rack cooling.

In-rack systems use a hot-aisle/cold-aisle strategy, this is where cool air is introduced to the front side of the servers, and server fans reject heat to the rear, where is it is then cooled by the  in-rack system.

These systems can reduce cooling demands by up to 60 percent by utilizing a greater air temperature differential than a traditional mixed cooling solution.

Cooling systems might involve refrigerant or chilled water.  Refrigerant can be routed overhead, and chilled water systems are best served from below a raised floor. Each option requires extensive careful planning and consideration to achieve efficiently and affordability.

– Commercial heating selection tips
Many HVAC professionals suggest calculating the expense for the first several years of ownership of your new commercial heating system, not just the installation cost, to help determine those that are truly most cost effective. You can reduce these costs by using high efficiency systems. The systems have high annual fuel utilization efficiency ratings(AFUE) and an Energy Star Seal of Approval, Rebates are frequently attached to these systems from government issuing agencies. Heating systems may vary, a temperate climate may warrant a different system than one with extreme temperatures during the winter and summer months.

Commercial Cooling Solutions for Work Spaces

Commercial Cooling Solutions for Work Spaces

cooling service in MOAmerican Services Commercial Cooling Installation in Overland knows that if your work space is full of heat generating electrical components and electronic devices, then you will need some heat removal systems. The comfort and wellbeing of your employees and safe operation of your equipment will depend on this. Conditioned air and proper ventilation are essential steps in creating a safe air conditioned environment that removes heat and circulates fresh air.

Some examples of these commercial buildings might be Schools, IT firms or manufacturing plants.

There are two types of commercial and industrial air conditioning. Modern cooling system technology uses ductless or split air conditioning. This allows the cooling unit and condenser to be located in a different location most generally on the rooftop. The cooling is thermostat controlled. Ducted cooling systems are inefficient and no longer installed in commercial applications.

Air cooling, water cooling, glycol cooling, and chilled water cooling are just a few of the cooling technologies still available today
Air cooled systems: widely used for its convenient ductless setup. The condensing unit is usually located outside, this helps with the exchange of the fresh air and removing of hot air. Because the cooling pipes are limited in length consideration must be made between workspace and the roof.
Glycol Cooling systems: though a very sophisticated cooling system
which produces temperatures below 50 degrees Fahrenheit. The coolant used in this system is Glycol it can be implemented over long distances and provide cooling to many workspaces with one condenser. This system requires more maintenance and constant monitoring of quality and quantity of the coolant Glycol.

Water cool systems: a cooling tower is used cool water which gets pushed back to the heat exchanger in the work environment. Benefits are multiple workstations can be cooled with just one single cooling tower. The cost of maintenance of cooling tower and quality of water may not be the best economic fit for your building.

Chilled water systems have a greater heat removing capacity. Cools larger areas with a greater efficiency and it only requires one
chiller plant. Possible setbacks can be installation charges; these are “extremely expensive” systems. Another concern should be the removal of most the moisture in the air (employee health problems). Careful consideration of your current building and its infrastructure a combination of one or more of these systems can be used to provide your air conditioning cooling systems.
