Liquid Based Active Solar Heating

Liquid Based Active Solar Heating

solor heating in MOAmerican Services heating installation service near Fairview Heights knows that solar liquid collectors are a viable option for central heating systems.  These are the same systems used in solar water heating.  Flat plate collectors are the most prevalent type available, but another version is the evacuated tube and concentrating collectors.  These are heat transfer fluid heating systems which use water, antifreeze, or other types of liquid which can absorb solar heat.

The controller operates a circulating pump to move the liquid through the collector.  As the fluid moves quickly through the system.  “Heating a smaller volume of liquid to a higher temperature increases heat loss from the collector and decreases the efficiency of the system. The liquid flows to either a storage tank or a heat exchanger for immediate use. Other system components include piping, pumps, valves, an expansion tank, a heat exchanger, a storage tank, and controls,” says Energy.gov.

In distributing heat for liquid systems, there are many options such as radiant floor, hot water baseboards, or even radiators, as well as forced air heat.  One of the best distribution methods is radiant floor heating for liquid solar systems because it works very well even at low environmental temperatures. Standard water heaters can be used as a back-up supply of heat.  Radiant slab systems finished with tile can take longer to heat than other distribution systems, but once they are heated up, they work very well to provide consistent heat.  The downside is that carpeting and rugs will lower the effectiveness.

“Hot-water baseboards and radiators require water between 160° and 180°F (71° and 82°C) to effectively heat a room. Generally, flat-plate liquid collectors heat the transfer and distribution fluids to between 90° and 120°F (32° and 49°C).”

Heat Pump Are Viable Options for Commercial Heating

Heat Pump Are Viable Options for Commercial Heating

industrial heating service in MOIn most cases heat pumps are used to heat and cool spaces.  However, in other instances they can be used to heat up water as well. Heat pumps can just heat the water or can be used to heat and cool spaces in tandem. Heat pumps use electricity to displace heat, rather than generating heat directly. For this reason, they can often be a good, efficient option for temperature control and for water heating.

A stand-alone heat pump water heater extracts warmth from the surrounding air and displaces it at a higher temperature into a reservoir where the water is then heated. Heat pump water heaters require setup in spaces that stay in the 40 to 90 degree Fahrenheit range. Furthermore, at least 1,000 cubic feet of air space is required for the pump to work properly. Beyond that, heat pumps will not function well in cold spaces, as they tend to cool when they operate already. Installing a combination heating, cooling and water heating system would mean pulling heat indoors from the outside in the winter and from the indoor air in the summer. That being said, any air-source heat pump system works better in a warmer climate.

Geothermal heat pumps pull up heat from the ground in the winter and from air inside during summer months, for heating and cooling. In order to heat water, a desuperheater can be used along with the geothermal heat pump. This device is a small heat exchanger that pulls superheated gases from the heat pump compressor to heat water. The water then gets stored in a water heater storage tank for usage on demand.

Industrial Heating for Apartment Complexes

Industrial Heating for Apartment Complexes

heating service for schools in MOAmerican Services heating service near Sunset Hills knows that heating an apartment complex can be an expensive and daunting task.  Depending on the location and climate, a heat pump might be a viable option.

A heat pump can be used as a part of an HVAC solution, which can save users money and lessen their potential environmental impact.  A heat pump serves as a transfer device that takes heat energy from a source and transfers it to a heat sink.  One way to think about it is looking at a computer that uses a fan to distribute air and a heat sink, which is a corrugated piece of metal, that absorbs the heat to keep the inside of the computer cool.  The principle behind a heat pump is similar except that the heat can be utilized to keep occupants warm.

Heat pumps come in a wide range of configurations.  The heat pumps can gather heat from air/water, rock, surface soil, or standing bodies of water.  Some heat pumps can also capture excess heat waste, like heat that comes out of exhaust vents or heat produced by a machine, such as a dryer.  This recapturing of waste heat is something that can be done easily and has the potential to save users hundreds or even thousands of dollars.

Heat pumps have been popular in Europe for some time and are gaining popularity state side.  Geothermal heat pumps offer the best of both worlds because they can maintain a constant temperature in a building no matter the temperature outside.  Air/water heat pumps are dependent on warm air to keep a consistent ambient temperature so they might not be applicable to all climates.

Heat pumps can be an option to help reduce costs and limit the CO2 that is pushed out into the environment.  So if you  are looking for an environmentally friendly solution that is also cost effective, then a heat pump could be just the option you need.

Industrial Rotary Screw Air Cooled Chillers

Industrial Rotary Screw Air Cooled Chillers

Industrial cooling chillers in MOIndustrial cooling chillers are a necessity to ensure productivity in the workplace.  Industrial rotary screw air cooled chillers incorporate new technology to ensure the same high reliability of previous chillers but allows for lower sound levels, increased efficiency, and a reduced footprint.  Specifically, advances in compressor design and performance make rotary screw air cooled chillers a viable option when seeking replacement of old equipment or when building a new facility.

The screw compressors were initially designed to replace design flaws that are found in reciprocating compressors.  One company leading the pack with the design of rotary screw air cooled chillers is Trane.  Trane has designed a helical rotary compressor and research has demonstrated a 99% reliability rating for the compressor during a one year period.  It is important to know that screw type chillers are produced by many companies and when seeking information, ensure that the company is reputable and will stand by their product.  It is also worth asking for contact information for other clients that have had similar systems installed to ensure the equipment has operated as expected.

With the use of helical rotary compressors there is no longer a need for a lot of extra moving parts.  A reciprocating compressor can have more than 15 times the number of critical parts as a rotary screw compressor.  Any time you have a mechanical piece of equipment, any part that moves has the potential to need replacement.  One of the great benefits of the helical rotary system is the reduction in parts that will potentially break.  Additionally, helical systems will typically have more durable parts compared to the reciprocating counterpart.

Basics of Air Duct Free HVAC Systems

Basics of Air Duct Free HVAC Systems

HVAC air duct systemAmerican Services commercial HVAC service in MO knows that Air duct free systems are a smart way to add air conditioning to multiple rooms without having to perform invasive installations of conventional duct systems. The systems will cost around $1,000 to $2,000 per unit and do an excellent job of cooling. In addition, the sound level is better than a conventional window air conditioning unit.

Air duct free systems, also known as ductless split HVAC systems are a matched combination of an outdoor condensing unit and an indoor fan coil unit by refrigerant tubing and wires. These systems are compact and take up very little space in the room. Additionally, they do not obstruct windows. New designs of ductless split HVAC systems are aesthetically designed to blend with room decor and new technologies with these systems ensure low sound levels.

HVAC air duct free systems are relatively inexpensive compared to modifying existing structure to run conventional air ducting. Specifically, the use of ductless systems are excellent for add-ons to current space or if you have a special space that requires varying environmental controls from the rest of the location. Additionally, if your current system is not able to handle modifications or additions, ductless systems are a viable option.

These type of HVAC systems are now being incorporated into many historical renovations where preserving the look of the original aesthetics in the structure. Requirements set on historical properties typically will not allow structure modifications even though they may have no cooling systems.

When assessing your location, look into a ductless HVAC system as an alternative to conventional methods.

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.

Natural Energy Heating Systems

Natural Energy Heating Systems

heating repair in St. LouisAmerican Services Cooling and Heating installation in Overland knows that the utilization of sustainable resources for the installation of commercial heating systems is a viable option today.

Some energy sources that power these systems are solar, and  geothermal power. HVAC options like these systems are not only eco-friendly, but in the long run will prove more energy cost efficient than the traditional oil and gas option. Some industry experts agree that initial installation costs can be an expensive investment and generally reserved for larger businesses.

Commercial heating alternatives

Gas or oil water systems:
This system is similar to steam heating in concept, there is a water heating method, usually a boiler, then  pushed through radiators throughout the property. This system is somewhat inefficient because you must clear the air in the system when  the heat is engaged causing delays in heating ,and creating unnecessary energy costs.

Heat Pump alternatives:
Another efficient alternative method of heating a commercial building is the implementation of the heat pump. The technology is similar to how a refrigerator works. The process essentially extracts heat from cold air.  Consider how warm the coils on the back of a refrigerator gets, add a refrigerant, and subsequently pump the heat that was generated throughout the commercial property.  This is an
extremely efficient system as it requires no fuel source to function.

Some commercial heating selection tips:
HVAC professionals suggest don’t just add up the installation costs to determine if your system is truly worth a sizable investment but suggests calculating the first several years of ownership of your new commercial heating system to better establish its “cost” versus energy savings.

You can also offset these costs using high efficiency systems. These superior systems are rated with high annual fuel utilization efficiency (AFUE) ratings and possess an Energy Star seal of approval and most generally are elgible for rebates. Finally you must consider the climate, A mild climate requires a different system than one with extreme temperatures during the winter and summer months.
