The purpose of this fact sheet is to provide an update on ASHRAE standards for refrigerants and to introduce the new refrigerants that have been awarded an "R" number over the last few years and introduced into the international market. This process is important in maintaining acceptable indoor air quality (IAQ) while maintaining low energy costs and reducing overall energy consumption. Carbon Dioxide Refrigeration SystemsCarbon dioxide (R-744) is one of the naturally occurring compounds collectively known as natural refrigerants. It is nonflammable and nontoxic, with no known carcinogenic, mutagenic, or other toxic effects, and no dangerous products of combustion. In-space heaters may be either permanently installed or portable and may transfer heat by a combination of radiation, natural convection, and forced convection. Coil defrost equipment is added for low-temperature operations when coil frosting might impede performance. In-Room Terminal SystemsVery early in the design process, the HVAC design engineer must analyze and ultimately select appropriate systems. Chapter 50. I believe this should be required training for anyone involved in HVAC and/or energy efficiency, because this class pulls so many of these concepts together. Maintaining the proper temperature and humidity levels in a data center is a critical task for any organization with an on-premises IT environment.

The primary products in the water refrigerant category are large commercial chillers, which use lithium bromide (LiBr) as absorbent. Air turbulence defeats the capability of hoods to contain and exhaust contaminated air. It has no adverse local environmental effects. In addition, steam is commonly used in heat exchangers (shell-and-tube, plate, or coil types) to heat domestic hot water and supply heat for industrial and commercial processes such as in laundries and kitchens. Motors, Motor Controls, and Variable-Frequency DrivesMany types of alternating-current (AC) motors are available; direct-current (DC) motors are also used, but to a more limited degree. Chapter 1. Im a true believer that ASHRAE has helped me in my pursuit of excellence through their certification program. Cameron R. Labunski, P.E. Boiler designs provide for connections to a piping system, which delivers heated fluid to the point of use and returns the cooled fluid to the boiler. The rapid pressure rise that occurs as the temperature rises above 450F (230C) increases cost because components rated for higher pressures are required.
