Aplication

A long-term non-ozone depleting replacement for R-502 and R-22 in low- and medium-temperature commerical refrigeration systems.R404A is made up of the components HFC125,HFC143a and HFC134a.The stability of R404A can be characterized based on the stability of its refrigerant components,in this case,by the known stability of R134a.

Retrofit:
R404A can be used to retrofit many existing R502 systems. The physical and thermodynamic properties of the blend cause it to behave much like R502 when used as a retrofit but it is not intended to be a direct “dropin” for R502 systems. Due to higher operating pressures associated with the use of R404A as opposed to R502, OEM product specific retrofit recommendations should be consulted for any and all pressure relief modifications and/or requirements.

Q: Why is dry ice not organic?: Inorganic compounds are pure metals that do not contain carbon and a collection of simple carbon compounds such as carbon monoxide, carbon dioxide, carbonates, carbonates and carbides.

Q: Hydrocarbons and hydrocarbon derivatives are not all non-electrolytes: Hydrocarbons are, derivatives are not necessarily, such as organic acids (formic acid, acetic acid, etc.)

Q: Artemisinin is not a derivative of hydrocarbons: A hydrocarbon is an organic compound (called a hydrocarbon) composed of two elements, carbon and hydrogen, and a hydrocarbon. Can be simply divided into open chain hydrocarbons, alicyclic hydrocarbons and aromatic hydrocarbons, all hydrocarbons are hydrophobic, that all the hydrocarbons are not soluble in water.

Q: Cracked: It is almost impossible for this problem to look at your reaction conditions. Generally speaking, the alkane reaction is mainly difficult to decompose directly into ions

Q: Is steel not organic synthetic material?: Organic compounds that are organic compounds. Carbon compounds (carbon monoxide, carbon dioxide, carbonic acid, carbonates, metal carbides, cyanide excluded) or hydrocarbons and their derivatives in general. Most of the combustion can produce carbon dioxide and water.

Q: Is the heterocyclic compound not a derivative of cyclic hydrocarbons? why?: The heterocyclic compound is an organic compound containing a heterocyclic structure in its molecule. The atoms that make up the ring contain at least one heteroatom in addition to carbon atoms. The heteroatoms include oxygen, sulfur, nitrogen and the like. Theoretically, the heterocyclic compound can be regarded as a derivative of benzene, that is, one or more CH in the benzene ring is replaced by a heteroatom. The heterocyclic compound may be in parallel with the benzene ring to form a fused ring heterocyclic compound.

Q: Other corals are because the color of the corals show colorful, why only the red coral is the exception of it? did not find the reasons for the big god to explain: Organic compounds, the general purpose of carbon compounds (carbon monoxide, carbon dioxide, carbonic acid, carbonate, metal carbide, cyanide excluded) or hydrocarbons and their derivatives.

Q: Why not ah?: A series of compounds in which a hydrogen atom in a hydrocarbon molecule is replaced by another atom or radical is called a derivative of a hydrocarbon

Q: What is organic?: Simply refers to the organic ingredients containing organic ingredients. The real organic cosmetics are organic plants as the main raw material, do not add artificial spices, artificial colors, oil-free ingredients, the added preservatives and surfactants must be strictly limited, and the manufacturing process to comply with the relevant provisions, can not use animals Experiments and the use of radiation sterilization products. In general, the certification of organic skin care products must meet the following conditions: First, the organic environment, the closest growth of natural growth, production base (ie, the environment) are not damaged, water (irrigation water), soil (soil ), Gas (air) is not contaminated. Second, organic cultivation, no artificial fertilizer irrigation or artificial feed, without antibiotics, chemical insecticide, without genetic variants. Third, the organic processing and production projects, including the harvest after washing, finishing, packaging, processing, transportation, storage, sales and other sectors) did not subject to secondary pollution.
