  • Effect of Insulations on Cop in Vapor Compression Refrigeration System

Dr N V V S Sudheer Associate Professor, R V R & J C College of Engineering, Guntur India ABSTRACT In this project, experimentation is done on Vapour Compression Refrigeration System [VCRS] as the COP is high for this system and it is the present trend of the HVAC in the domestic industry. This study presents investigation of best suited refrigerant and insulation combination for gas pipeline and liquid pipeline of a split air conditioning system. Analysis are performed for R22-Chlorodiflouromethane, a HydroChloroFlouro Carbon refrigerant, which has been using in the present world that cause both global warming and ozone layer depletion and R410a, mixture of di- flouromethane and pentaflouroethane, a Hydroflouro carbon refrigerant, which is future of HVAC which reduces the effect of ozone layer depletion [ODP] and Global Warming Potential [GWP].For these two refrigerants, we had found out the best insulation suitable as insulation also affects the COP of air conditioner, which has been observed from the literature. Minimizing the temperature of refrigerant in suction line helps condensing unit work more effectively intern the system performance increases. This reduces the overall power required for working of air conditioner, thereby reducing the maintenance cost of system.

CHEMICAL PRODUCT AND COMPANY IDENTIFICATION PRODUCT NAME: R-22 OTHER NAME: Chlorodifluoromethane USE: Refrigerant Gas DISTRIBUTOR: National Refrigerants, Inc. 661 Kenyon Avenue Bridgeton, New Jersey 08302 FOR MORE INFORMATION CALL: IN CASE OF EMERGENCY CALL: (Monday-Friday, 8:00am-5:00pm) CHEMTREC: 1-800-424-9300 1-800-262-0012 2. HAZARDS IDENTIFICATION CLASSIFICATION: Gases under pressure, Liquefied Gas SIGNAL WORD: WARNING HAZARD STATEMENT: Contains gas under pressure, may explode if heated SYMBOL: Gas Cylinder PRECAUTIONARY STATEMENT: STORAGE: Protect from sunlight, store in a well ventilated place EMERGENCY OVERVIEW: Colorless, volatile liquid with ethereal and faint sweetish odor. Non-flammable material. Overexposure may cause dizziness and loss of concentration. At higher levels, CNS depression and cardiac arrhythmia may result from exposure. Vapors displace air and can cause asphyxiation in confined spaces. At higher temperatures, (>250C), decomposition products may include Hydrochloric Acid (HCI), Hydrofluoric Acid (HF) and carbonyl halides. POTENTIAL HEALTH HAZARDS SKIN: Irritation would result from a defatting action on tissue. Liquid contact could cause frostbite. EYES: Liquid contact can cause severe irritation and frostbite. Mist may irritate. INHALATION: R-22 is low in acute toxicity in animals. When oxygen levels in air are reduced to 12-14% by displacement, symptoms of asphyxiation, loss of coordination, increased pulse rate and deeper respiration will occur. At high levels, cardiac arrhythmia may occur. INGESTION: Ingestion is unlikely because of the low boiling point of the material. Should it occur, discomfort in the gastrointestinal tract from rapid evaporation of the material and consequent evolution of gas would result.

  • 181 Chloroform 4. Production, Import/Export, Use, And
    CHLOROFORM 181 4. PRODUCTION, IMPORT/EXPORT, USE, AND DISPOSAL Chloroform is used primarily in the production of chlorodifluoromethane (hydrochlorofluorocarbon-22 or HCFC-22) used as a refrigerant for home air conditioners or large supermarket freezers and in the production of fluoropolymers (CMR 1995). Chloroform has also been used as a solvent, a heat transfer medium in fire extinguishers, an intermediate in the preparation of dyes and pesticides, and other applications highlighted below. Its use as an anesthetic has been largely discontinued. It has limited medical uses in some dental procedures and in the administration of drugs for the treatment of some diseases. 4.1 PRODUCTION The chlorination of methane and the chlorination of methyl chloride produced by the reaction of methanol and hydrogen chloride are the two common methods for commercial chloroform production (Ahlstrom and Steele 1979; Deshon 1979). The Vulcan Materials Co., Wichita, Kansas, was documented as still using the methanol production process during the late 1980s with all other facilities in the United States at that time using the methyl chloride chlorination process (SRI 1990). One U.S. manufacturer began chloroform production in 1903, but significant commercial production was not reported until 1922 (IARC 1979). Since the early 1980s, chloroform production increased by 20-25%, due primarily to a higher demand for HCFC-22, the major chemical produced from chloroform. The Montreal Protocol established goals for phasing out the use of a variety of ozonedepleting chemicals, including most chlorofluorocarbons (CFCs). HCFC-22 was one of the few fluorocarbons not restricted by the international agreement. Chloroform is used in the manufacture of HCFC-22, and an increase in the production of this refrigerant has led to a modest increase in the demand for chloroform (CMR 1989).
