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: What are the gaseous states of the oxygen-containing derivatives of the hydrocarbons under the standard conditions?: Halide only fluoride in normal temperature and pressure may be gaseous;

Q: What is the hydrocarbon thing: Hydrocarbons can be divided into: open chain hydrocarbons (carbon atoms in hydrocarbon molecules in open chain) - saturated hydrocarbons - alkanes - unsaturated hydrocarbons - olefins and polyolefins (carbon - carbon double bonds, unstable) - alkynes and (Cyclopentane) - cycloalkene - cycloalkyne aromatic hydrocarbon - monocyclic aromatic hydrocarbon (benzene and its homologues) - fused ring aromatic hydrocarbons (Polycyclic aromatic hydrocarbons and their homologues) - polycyclic aromatic hydrocarbons (naphthalene, anthracene and other condensed ring aromatic hydrocarbons and their homologues) all hydrocarbons are hydrophobic, that all the hydrocarbons are not soluble in water and coal The main ingredients are hydrocarbons

Q: What is the difference between crude oil and asphalt?: Financial institutions, financial management, cash exchange, the exchange of foreign exchange private schools

Q: What is "organic" and "inorganic" in chemistry?: The definition of organic matter usually refers to carbon-containing compounds, or hydrocarbons and their derivatives are collectively referred to as organic compounds.

Q: Does Organic Chemistry Study the Performance of Hydrocarbons and Their Derivatives?: Also study the structure and transformation

Q: What is the difference between hot and cold asphalt?: According to the time analysis, municipal companies should use the cold asphalt cold material, is the winter road maintenance of commonly used materials. In the long winter, the asphalt pavement works because of the temperature (less than 5 degrees is strictly prohibited construction), is very little construction, even if the construction, the quality is higher than the temperature when the construction is worse (asphalt mixture cold fast, easily lead to compaction The lack of pressure on the pressure, and prone to cohesive, poor water quality problems such as water), because no demand or demand is small, this time the major asphalt mixing field have a holiday home to the New Year. But the road will be the same as the winter disease, pit and other small diseases are not treated in time, easy to evolve into a large disease, there may be dangerous roadbed, running up the driver also curse, out of the accident maintenance department also bear responsibility, so the winter road Also need to maintain. At this time asphalt cold feed came into being, asphalt cold feed is used aggregate (graded gravel) plus dehydration asphalt plus diesel and additives mixed with the construction of the temperature requirements, the pits filled with pavement , Such as diesel fuel has finished bitter gluing together, but the construction quality is not good, no hot mix asphalt dense. So the winter is approaching, the road maintenance department will need to mix a few tons of asphalt cold feed sealed (to participate in 25kg rice), there are pits to pull a few bags to fill, and so on these problems when the pit and digging with the heat Mixed with asphalt material repair. In summary, the asphalt cold feed is a special winter pavement pit repair using the material, the construction process and hot mix asphalt material is roughly the same, but the construction quality is relatively poor, is a special time emergency measures, very useful materials.

Q: Organic chemistry studies the performance of hydrocarbons and their derivatives, either right or wrong: Correct

Q: Are hydrocarbons all organic?: A series of organic compounds, also known as "hydrocarbons." Many types, according to the structure and nature,

Q: Such as the title, the personal feeling of chemical transliteration of Chinese transliteration can be done so easy to write, weird name in addition to keep the high point, no good, but rather affect the people's understanding of medicine and memory, contrary to the text to facilitate the exchange of memory Original intention: China's chemical name may be the best of both Latin and English

Q: Why does the hydrocarbon derivative make the bromine water fade and the hydrocarbon can not: As long as carbon and carbon double bonds and three hydrocarbons can be hydrocarbons
