Liquid to Vapor Propane Evaporators
These evaporators serve a large complex where natural gas is unavailable. The complex needed fuel for boilers for heating and domestic hot water so these evaporators were installed too along with two very large LP tanks to handle the heating needs of the complex. As liquid propane (LP) has a specific weight of .504 (where water is 1) and propane vapor has a specific gravity of 1.5 (where the air is 1) making propane vapor 1.5 times heavier than air. (more…)

Air Conditioning and Heating HVAC Heat Energy Values - Heat is energy and when we produce heat we need to use energy in its production. There are natural methods for producing heat without burning or using fuels but these methods are not practical or available to the general populace for residential, commercial, and industrial use.
The production of heat, whether for residential, commercial, or industrial uses, uses energy, and energy costs money. It is thereby necessary to have reliable and proven methods of measuring the amount of heat produced using a specific quantity of energy. Employing these reliable and proven methods we can also use the data to determine the best methods of producing heat for homes, businesses, and industry. (more…)
