Phase I refrigerant concentrations (i.e., 10%, 50%, 95%), refrigerant concentrations of 20, 35, 65, 80 and 90% were tested for miscibility. It is compatible with mineral oil and compared to mineral oil, it has improved refrigerant miscibility at low-temperature conditions which is why it was and is often used with HCFC refrigerants in commercial refrigeration. i'm looking for answers to an assignment thats due in real soon. Get help determining the appropriate refrigeration oil lubricant required for your system. Service Application Manual SAM Chapter 620-107 Section 1A SELECTION OF REFRIGERATION OILS FOR R32 3.1 Points in Selecting Refrigeration Oils for R32 There are three points to be considered when selecting refrigeration oils for R32: the first is the miscibility with R32 refrigerant, the second is to keep of the viscosity when R32 refrigerant is dissolved, and the third is the stability of The oil comes in direct contact with hot motor windings are sealed units. Because it is mixed with the refrigerant refrigerant and oil must have certain properties. The basis for selecting the lubricant-refrigerant combinations that were tested in Phase II is that the combination must have demonstrated single-phase miscibility in at least one of the three test Other oils may or may not react in a similar manner. Compatibility of lubricants with refrigerant fluids; ... including any related processing for purposes of providing me this information. Alternate Refrigerant Blends and Material Compatibility with Rubber Materials in Mobile Air Conditioning This test program is a part of on-going research by Santech ... Only one Mineral Oil, one Polyalkylene Glycol Oil, and one Polyol Ester Oil was selected for the test. If refrigerant oil did the same thing—that is, if it remained in the compressor crankcase—it would eliminate many oil-related problems in refrigeration systems. Start with this helpful technical topic, as well as our refrigeration oil selection guide. Oil in the refrigeration system is cooled at low temperatures. MATERIALS COMPATIBILITY AND LUBRICANTS RESEARCH ON CFC-REFRIGERANT SUBSTITUTES Quarterly MCLR Program Technical Progress Report 1 April 1993 - 30 June 1993 David S. Godwin Glenn C. Hourahan Steven R. Szymurski Air-conditioning and Refrigeration Technology Institute, Inc. 4301 North Fairfax Drive, Suite 425 Arlington, Virginia 22203 July 1993 I am a first year apprentice refrigeration mechanic from sydney australia. Nonflammable and with low toxicity, the direct replacement Freon Hot Shot™ 2 provides other benefits, including: Compatibility with mineral, alkylbenzene, and POE oils 3. Therefore, it is important that the oil and the refrigerant are miscible with each other so that oil following the refrigerant out in the system is returned to the compressor and not accumulated in the system. HFC refrigerants … National Number; Bitzer B100: Mineral Oil: 500 SUS / 100 ISO: NL 500: Bitzer 5.2: Alkylbenzene: 150 SUS / 32 ISO: NL AKB 150: Bitzer BSE 32: Polyolester: 32 ISO / 150 SUS Mueller Refrigeration Product Compatibility with Refrigerants and Refrigeration Oils The following refrigerants and oils were tested on all of Mueller's current product components: Refrigerant Refrigerant Oil Compatibility R-11 Mineral Alkylbenzene Yes R-12 Mineral Alkylbenzene Yes R-22 Mineral Polyol Ester (POE) Yes R-113 Mineral the oil in the refrigeration system is a contaminant that lowers the efficiency of the refrigeration system. Retrofitted systems that use Freon Hot Shot™ 2 refrigerant don't require a costly, time-consuming oil change because the refrigerant is compatible with all compressor oils. 3. Alkylbenzene (AB) – a synthetic oil suitable for refrigeration systems using CFC or HCFC refrigerants. Thus, it must be able to withstand temperature extremes and harmlessness for refrigerants and equipment.
