Refrigerant. A refrigerant is a working fluid used in the refrigeration cycle of air conditioning systems and heat pumps where in most cases they undergo a repeated phase transition from a liquid to a gas and back again. Refrigerants are heavily regulated because of their toxicity and flammability and the contribution of CFC and HCFC ...
According to ASHRAE standard 34, the R-number of a chemical refrigerant is assigned systematically according to its molecular structure and has between two and four digits. If there are carbon -carbon multiple bonds , there are four digits in all: the number of these bonds is the first digit and the number of carbon atoms minus one (C-1) is next.
Difluoromethane, also called difluoromethylene, HFC-32 Methylene Fluoride or R-32, is an organic compound of the dihalogenoalkane variety. It has the formula of CH 2 F 2. It is a colorless gas in the ambient atmosphere and is slightly soluble in water, with a high thermal stability. [2] [failed verification] Due to the low melting and boiling ...
Vapour-compression refrigeration or vapor-compression refrigeration system ( VCRS ), [ 1] in which the refrigerant undergoes phase changes, is one of the many refrigeration cycles and is the most widely used method for air conditioning of buildings and automobiles. It is also used in domestic and commercial refrigerators, large-scale warehouses ...
Variable refrigerant flow systems when compared with central plant cooling from an air handler, eliminate the need for large cool air ducts, air handlers, and chillers; instead cool refrigerant is transported through much smaller pipes to the indoor units in the spaces to be conditioned, thus allowing for less space above dropped ceilings and a ...
Brine (or briny water) is water with a high-concentration solution of salt (typically sodium chloride or calcium chloride).In diverse contexts, brine may refer to the salt solutions ranging from about 3.5% (a typical concentration of seawater, on the lower end of that of solutions used for brining foods) up to about 26% (a typical saturated solution, depending on temperature).
Natural refrigerants are one of the potential options for replacement of HFCs, and are growing in usage and popularity as a result. The natural refrigerant industry is expected to have a compounded annual growth rate of 8.5% over the next 4 years, [ 10] and is expected to become a US$2.88 billion industry by 2027. [ 2]
Media: Bagoong. Bagoóng ( Tagalog pronunciation: [bɐɡuˈʔoŋ]; buh-goo-ONG) is a Philippine condiment partially or completely made of either fermented fish ( bagoóng isdâ) or krill or shrimp paste ( bagoóng alamáng) with salt. [1] The fermentation process also produces fish sauce known as patís. [2]
