R22 refrigerant msds pdf

Rea cannot be seen as a full replacement. A disadvantage, however, is the lower volumetric refrigerating capacity. Ra Isobutane will be an interesting alternative if safety regulations allow the use of hydrocarbons safety group A3.

The volumetric refrigerating capacity is almost identical to R At identical refrigerating capacities, the mass flow differs only slightly.

However, like Ryf, Rze E shows low flammability and is therefore classified into the new safety group A2L. The corresponding safety regulations must be observed. As no sufficient operating experience is available so far, the suitability of this refrigerant for long-term use cannot be assessed yet. However, only purpose-built compressors and system components can be used here. Another advantage is their very low GWP and the classification in safety group A1 non-flammable, non-toxic.

A detailed evaluation of these refrigerants is not yet possible with respect to the chemical stability of the refrigerants and of the lubricants at the very high operating temperatures and the long service life required for industrial systems.

In addition to the potentially suitable substances listed in the table above, a series of other fluids are possible, depending on the temperature level of the heat source and heat sink. Solvay offers further refrigerants for ORC applications, containing the base component Rmfc.

In ORC systems zeotropic behavior may be advantageous. This leads to improved heat transmission due to the higher driving average temperature difference. Screw and scroll compressors can be adapted by construction as an expander for ORC systems. BITZER has been involved in various projects for several years and has already been able to gain important insights with this technology, which have been implemented in the design of screw expanders and their application.

An individual expander design is available upon request. Further information is available upon request. For RA, a substantially higher discharge gas temperature than for R13B1 is to be considered, which restricts the application range even in 2-stage compression systems to a greater extent.

Meanwhile, production has ceased. However, for historical reasons the refrigerant will continue to be included in this Report. It is a mixture of R and R with a small proportion of R Due to the properties of the two main components, density and mass flow are relatively high, and discharge gas temperature is very low. Liquid subcooling is of particular advantage.

Both of the mentioned refrigerants have fairly high pressure levels and are therefore limited to In addition to this, the steep fall of pressure limits the application at very low temperatures and may require a change to a cascade system with e. It is therefore imperative to develop alternative solutions for which, however, no overall recommendation is possible. Two-stage compressors may be operated e. At evaporating temperatures of down to R ethane is also suitable if the safety regulations allow a flammable substance safety group A3.

Due to the partly steeper pressure curve of the alternative refrigerants and the higher discharge gas temperature of R23 compared to R13, differences in performance and application ranges for the compressors must be considered. Heat exchangers and controls have to be adapted individually. R is also well soluble with conventional oils, but an adaptation to the temperature will be necessary.

Hence, the exemption described in the previous chapter in the EU F-Gas Regulation applies in particular. Even relatively small quantities are therefore very much at the expense of the available quotas.

In many cases, however, the use of A3 refrigerants is not possible or would involve unjustifiable expenses and high costs in the relevant special applications. Specific Heat of Liquid 0.
