More Heating and Cooling Options and Details

propaneIn our research on behalf of your heating and cooling experts in St Louis near South County, we have been looking at heating and cooling solutions from multiple angles.  Covering the two types of furnaces, atmospheric and condensing is what we just finished doing.  Now, we consider that the best gas furnaces and boilers today have efficiency over 90%.

When it comes to efficiency, there is a difference between them.  “The efficiency of a fossil-fuel furnace or boiler is a measure of the amount of useful heat produced per unit of input energy (fuel). Combustion efficiency is the simplest measure; it is just the system’s efficiency while it is running. Combustion efficiency is like the miles per gallon your car gets cruising along at 55 miles per hour on the highway.”  When it comes to regulations, the minimum AFUE, or annual fuel utilization efficiency, estimates seasonal efficiency, averaging peak and part-load situations. “AFUE accounts for start-up, cool-down, and other operating losses that occur in real operating conditions, and includes an estimate of electricity used by the air handler, inducer fan, and controls. AFUE is like your car mileage between fill-ups, including both highway driving and stop-and-go traffic. The higher the AFUE, the more efficient the furnace or boiler.”

Boilers are an interesting subject and product.  They are special purpose water heaters.  According to our St Louis Cooling repair near South County, it is true that while furnaces carry heat in warm air, boiler systems distribute the heat in hot water, which gives up heat as it passes through radiators or other devices in rooms throughout the house.  Then, when the cooler water is set, it runs, returning to the boiler to be reheated.  Hydronic systems are systems that run on hot water.  Residential boilers are usually natural gas or heating oil for fuel.

Focus On – Cooling Towers

Focus On – Cooling Towers

St Louis Commercial Cooling ServiceHave you ever wondered what a cooling tower is how it can work for providing air conditioning to your commercial property?  If so, today’s focus on cooling towers is perfect for you!  Let’s get started with a quick overview regarding the actual function of this type of unit.

According to www.HowStuffWorks.com, a cooling tower works like this, “The tower creates a stream of cold water that runs through a heat exchanger, cooling the hot condenser coils. The tower blows air through a stream of water causing some of it to evaporate, and the evaporation cools the water stream.”  It is noted that a disadvantage associated with this type of system is that water has to regularly be added to make up for evaporated liquid loss and that the efficiency of this type of unit relies heavily upon the relative humidity of the air, along with the barometric pressure.  Just a few things to think about!

The team at American Services wants you to completely understand your cooling options.  Please feel free to contact our Florissant area commercial cooling sales department to get all the details regarding the cooling tower-based systems we have to offer.  Our team can additionally help you with a full range of HVACR needs.  Our list of services includes: HVAC services like rooftop packaged units, split systems, boilers and chillers; Refrigeration units like walk-ins and reach-ins; Industrial Equipment like chillers, exhausts, and make-up air; Cooking Equipment like grills, ovens, fryers, and steamers; plus Beverage Equipment like coffee, cappuccino, soda, and frozen beverages.

Alternative Heating Sources

Alternative Heating Sources

solor heating in MOAmerican Services Heating and Cooling installation service in Missouri knows that there are many options when it comes to commercial heating systems.

One such option is for heat transfer fluids.  If you are considering solar heating heat transfer systems, be sure to consult the local authority in your area to find out what exactly is required for your geographic area.

Water is one type of substance that is effective as a heat transfer fluid, particularly with its low viscosity property which makes it easy to pump. Drawbacks are its low boiling point and high freezing point, and the fact that water can be corrosive and cause mineral deposits.

Glycol and water mixtures are made up of a 50/50 or 60/40 glycol-to-water ratio. Ethylene and propylene glycol make up the properties of antifreeze.

Hydrocarbon oils have a higher viscosity and lower specific heat than water meaning they need more energy for circulation.  With a low freezing point, these types of oils tend to be relatively less expensive than some others.     The basic categories of hydrocarbon oils are synthetic hydrocarbons, paraffin hydrocarbons, and aromatic refined mineral oils. Synthetic hydrocarbons are relatively nontoxic and require little maintenance. Paraffin hydrocarbons have a wider temperature range between freezing and boiling points than water, but they are toxic and require a double-walled, closed-loop heat exchanger. Aromatic oils are the least viscous of the hydrocarbon oils.

Refrigerants are commonly used in refrigerators, air conditioners, and heat pumps as the primary heat transfer fluid. They generally have a low boiling point and a high heat capacity which enables a small amount of the refrigerant to transfer a large amount of heat very efficiently.

If you currently own a refrigerant-charged solar system that requires maintenance, contact us today at American Services and we will sent out a qualified technician.

Active solar heating uses solar energy to heat transfer fluid or air, which then transfers the solar heat to an interior  storage system for later use. Solar heating systems can be implemented as a supplement to other heating systems such as radiant heating, boilers, heat pumps, or forced-air heating systems.

Active solar heating systems are actually most cost-effective in cold climates that have good solar resources.  Liquid and air systems are good choices for forced air supplemental heating. Note that commercial systems usually come with warranties of 10 years or more and usually last much longer.

HVAC History

HVAC History

antique stove for HVAC in MOAmerican Services HVAC repair and installation in St. Louis knows that in the 1700s and 1800s heating stoves made of brick were most commonly used. Additionally, the first mercury thermometer was invented, making temperature reading easy and accurate.  Benjamin Franklin invented the very first stove known as the first steam heating system during this time period. In England, direct fired heat exchange technology, using a stove with a furnace, was being used to warm up large factories.

In this 200 year span, Joseph black forged ahead with relevant discoveries on the topic of latent heat and James Watt was to forever be included in the history books by inventing the steam engine. Carnot initiated thermodynamics and the first and second laws of thermodynamics were made. James Joule discovered and published that work produces heat. For the first time heat was treated as a form of energy. Also, the first warm furnace was developed and boilers with higher capacity were used. Laws of gases were discovered and widely put to use.

The 20th century was a bustling time period for the advancement of HVAC technology. This era saw numerous inventions and rapid evolution of the HVAC systems. Furnace system with centrifugal fans, high pressure steam heating systems, massive fan systems and high speed centrifugal fans and axial flow fans with small electric motors were in extremely high usage.  Industrial air conditioning systems were devised by Sturtevant and Buffalo Forge designed a system to remove dust particles from air streams.

A cooling system was devised that could lower temperature to 10 degree Fahrenheit and a forced air system using a fan was made. The first centrifugal refrigeration machine was made for air conditioning large spaces, while hydronic circulatory pumps and radiators started to be used in the air conditioning systems for circulating water in the system. Furthermore, the first refrigeration with a compressor was made. In the 1900s the first residential air conditioning was made, panels for heating floors and ceilings were manufactured and the use of solar power as a power source was made.

Forms of Radiant Heating Available

Forms of Radiant Heating Available

heating repair in MOAmerican Services heating and cooling repair in St. Louis knows that as it is stated on the website energy.gov, “Radiant heating has a number of advantages.” It is more efficient than baseboard heating and usually more efficient than forced-air heating because it eliminates duct losses. People with allergies often prefer radiant heat because it does not distribute allergens like forced air systems can. Hydronic (liquid-based) systems use little electricity, a benefit for buildings off the power grid or in areas with high electricity prices. Hydronic systems can use a wide variety of energy sources to heat the liquid, including standard gas- or oil-fired boilers, wood-fired boilers, solar water heaters, or a combination of these sources.”

One type is air-heated radiant floors. Since air can’t hold large amounts of heat, air-heated floors are not cost-effective in residential construction. Sometimes they can be combined with solar air heating systems. However in these situations, heat is only produced in the daytime. It is inefficient to attempt to heat a home with a conventional furnace by pumping air through the floors at night, even with the benefits of using solar heat during the day.

Hydronic systems can use a wide variety of energy sources to heat the liquid, including standard gas- or oil-fired boilers, wood-fired boilers, solar water heaters, or a combination of these sources.” . Electric radiant floors can also be used for home additions if it would be difficult to use the existing heating system in the new space,

Hydronic, or liquid-based, systems are the most widely used and cost-effective radiant heating systems for in cooler climates. Hydronic radiant floor systems pump heated water from a boiler through tubing laid underneath the floor. Hydronic radiant heat is certainly a topic that can be an efficient energy option for builders to use in a variety of different construction scenarios.

Alternate Heating Sources for Commercial Greenhouses

Alternate Heating Sources for Commercial Greenhouses

industrial heating system in MOAmerican Services industrial heating equipment repair in St. Louis knows that the type of fuel that is best for commercial greenhouse heating depends on many factors such as; price, convenience and availability.

Some fuel sources put out a higher heating value than others.   A good method for comparing the cost of fuel is by utilizing the million Btu basis. In other words what is the cost of one million Btu’s of heat? By definition, one Btu equals the amount of energy required to raise a pound of water 1ºF. It takes 8.3 Btu’s to raise 1 gallon of water 1ºF.

Gas Vapor Fuels

Natural gas is one of the most economical and clean fuel sources available today, although it is not always available to industrial greenhouse owners in all geographic areas of the country.  Natural gas requires no on-site expensive storage equipment as it is piped directly from transmission lines. Natural gas burns cleanly, requires little equipment maintenance, and may be used in central boilers or remote unit heaters. Some suppliers include an “interruptible clause” which allows them to interrupt the supply in time of extreme need, usually during cold spells when fuel is needed to heat homes. Locating and securing a backup fuel supply and equipment to burn it is essential under these conditions.

For larger volume users, it is best to buy “direct purchase” from one of the large suppliers. Adding the transmission cost through the pipelines will give you a total fuel cost.

Propane (Liquefied Petroleum Gas) is a clean, gaseous fuel similar to natural gas. It is derived from a byproduct of oil refinery manufacturing or by stripping natural gas. It is liquefied by a moderate pressure process at normal temperatures. Even though propane is more expensive than natural gas it can be readily obtained where natural gas in not available. Maintenance is minimal, but a storage tank, preheater, and pumping network costs must be considered.

Propane is best purchased by the transport load which requires a 30,000 gallon tank.

Fuel Oil #2 #4  #6

No. 2 oil is usually comparably priced with natural gas but may be more expensive in some locations especially where it has to be transported a long distance from the supply point. It is a relatively clean fuel that demands slightly more burner maintenance than gas. Oil requires on-site infrastructure; above ground storage tanks that must have a containment in event of a leak or spill. Oil stored in outdoor, above-ground tanks may become difficult to pump in environments where temperatures can hover near 0ºF. Insulated tanks or additives to the fuel protect against this hazard.

No. 4 and 6 oils possess a higher heating value than No. 2 but because of low sulfur emission restrictions, they are usually similar in price. These oils require a preheating and greater attention to equipment operation. They are subject to the same storage and temperature limitations as No. 2 oil

Advanced HVAC Capabilities for Commercial Buildings

Advanced HVAC Capabilities for Commercial Buildings

HVAC repair in MOWhile reduced energy savings is the most popular reason for using new HVAC technology, many technology systems today offer capabilities that are difficult or almost impossible to interact with other systems.

Take for example, the capabilities of the new generation of digital boiler control systems, it not only provides more efficient operation. but the control systems offer remote monitoring capabilities. What this means, is that operators can monitor and modify the operation of boilers from practically anywhere in the building.

Safety is an area that is expanding rapidly in the HVAC industry. Safety is enhanced through a constant monitoring of a wide range of operating parameters; even system reliability is enhanced- this mechanical technology was unheard of 10 years ago.

This new safety enhancement in system operations takes place in all modern HVAC system
technologies on the market today. This aids the facility executive and his maintenance staff in assessing the status of his commercial building, and needs of any occupants.  This improves overall system reliability.

Despite all the benefits and capabilities of new technology associated with HVAC systems, to be effective they must be compatible with existing facility “needs and infrastructure.” Even the most technologically advanced system will not be of much benefit if it cannot be used effectively with your commercial building.

Tips for considering investing in HVAC technology:

1. Consult a certified HVAC installer such as American Services HVAC installation service in St. Louis. This is a good place to start getting a detailed examination of your facility.

2. Identify the needs of your building.

3. Select the appropriate HVAC system for your application

If it’s a goal to reduce energy costs, it is recommended by professionals to identify systems and components that will provide the greatest impact. You can’t always upgrade all components. Layout an implementation phased plan and start with the high priority components, and high pay back value items.
