Types of Fire Pumps. A fire pump is a specialized water pump that provides constant, high pressure for a water system used to extinguish fires. The fire pump intake can be connected to an underground water pipe or a static source, such as a water tank or reservoir. Fire pumps may be powered by an electric or diesel motor.
ASHRAE 90.1 (Energy Standard for Buildings Except Low-Rise Residential Buildings) is a US standard that provides minimum requirements for energy efficient designs for buildings except for low-rise residential buildings. The original standard, ASHRAE 90, was published in 1975.
The MERV rating system was initially created by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (or ASHRAE for short) in 1987. However, this evaluation system was based on older methods that date back to 1968, when ASHRAE issued Standard 52, the first formal testing standard for filters.
