American 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.
