Refrigerant Phase Out


refrigerant phase out
    refrigerant
  • Causing cooling or refrigeration
  • any substance used to provide cooling (as in a refrigerator)
  • causing cooling or freezing; "a refrigerant substance such as ice or solid carbon dioxide"
  • (refrigeration) the process of cooling or freezing (e.g., food) for preservative purposes
    phase out
  • the act or instance of a planned discontinuation
  • An act of discontinuing a process, project, or service in phases
  • terminate gradually
  • the gradual reduction of a government regulation or trade barrier (chapter 17)
refrigerant phase out - Vapor Compression
Vapor Compression Heat Pumps with Refrigerant Mixtures
Vapor Compression Heat Pumps with Refrigerant Mixtures
Amidst tightening requirements for eliminating CFC’s, HCFC’s, halons, and HFC’s from use in air conditioning and heat pumps, the search began for replacements that are environmentally benign, non-flammable, and similar to the banned refrigerants in system-level behavior. Refrigerant mixtures are increasingly used as working fluids because they demonstrate desirable thermodynamic, feasibility, and safety characteristics.
Vapor Compression Heat Pumps with Refrigerant Mixtures provides the first comprehensive, single-source treatment of working fluid mixtures and their applications in vapor compression systems. The authors explain in detail the thermodynamics of refrigerant mixtures, which is vastly more complex than that of individual refrigerants, as well as the fundamentals of various refrigeration cycles and methods for improving their efficiency. They also include important discussions on heat transfer and pressure drop correlations, experimental performance measurements and examples of using refrigerants and their mixtures, and critical operational issues such as control issues, refrigerant mixing, and mass fraction shifts.
Assembling reviews of the scattered literature on the subject and reflecting two decades of research by the authors, Vapor Compression Heat Pumps with Refrigerant Mixtures prepares you to design and implement systems that take the best advantage of fluid mixtures, confronting the challenges and grasping the opportunities that they present.

Mitsubishi GTO
Mitsubishi GTO
The Mitsubishi GTO is a sports car built by Japanese automaker Mitsubishi Motors between 1990 and 2001, although in most export markets it was rebadged as a Mitsubishi 3000GT. It was also sold by Chrysler in North America as a Dodge Stealth captive import from the 1991 to 1996 model years with only minor detail/appearance differences. It took its name from the Galant GTO, a two-door hardtop coupe sold by the company in the early 1970s. Following the successful showing of the Mitsubishi HSR concept car at the 1989 Tokyo Motor Show,[1] Mitsubishi developed the new GTO as a technically advanced sports coupe to compete with the Honda NSX, Mazda RX-7, Nissan 300ZX, Skyline GT-R, and the Toyota Supra. They resurrected the GTO name, and the car went on to serve as Mitsubishi’s flagship for the remainder of the decade. However, despite the cachet of the badge at home, it was known as the Mitsubishi 3000GT outside Japan; the company was concerned that connoisseurs would object to the evocative nameplate from the highly regarded Ferrari 250 GTO and Pontiac GTO being used on a Japanese vehicle. However, regardless of its badge or eventual target market, every car was built on the same production line at Mitsubishi's plant in Nagoya, Japan. The first generation incorporated many of Mitsubishi's contemporary performance-enhancing technologies, such as full time four-wheel drive, four-wheel steering, active aerodynamics featuring automatically-adjusting front and rear spoilers, sport/tour exhaust modes and electronically controlled suspension (ECS). Visually, the cars featured pop-up headlights and noticeable "caps" on the bonnet to accommodate the ECS controllers at the top of the strut turrets. Second generation models are identified by a revised front bumper to accommodate projector beam headlights and small, round projector fog lights. The caps on the bonnet were replaced with integrated blisters and the side air vents and rear bumpers were modified. The interior was redesigned with dual air bags, a new audio system and revised air conditioning refrigerant. The engines in all models received a slight boost in torque from 416 Nm to 427 Nm). To complement this, the VR-4 now included a six-speed Getrag manual transmission. Bigger wheel/tire combinations were provided beginning in 1995. The base and SL model received 16" wheels in silver or chrome with 225/55 tyres, while the VR4 now had 18" chrome wheels with 245/40 tires (the Spyder had the standard 17" with higher profile tires from 1994 to handle the additional 180 kg. As the price of the cars increased, many of the gadgets on the car were discontinued. The tunable exhaust was phased out after model year 1994, the ECS disappeared after the 1995 model year and the active aerodynamics in 1996. Finally, Chrysler ceased sales of the Dodge Stealth captive import and for the remainder of its life only Mitsubishi-badged versions were available. The SOHC 12v engine, previously only available in the base model Stealth, was added to the Mitsubishi range after the Dodge version was discontinued. A planned facelift for 1997 being abandoned in favour of minor cosmetic adjustments, including a new front bumper. In 1999 the car received a partial exterior facelift, including new front bumper, headlamps, indicators and a large spoiler for the 1999 VR-4 to distinguish it from previous models. Production finally ceased in 2000, with the last two cars sold the following year.

Mr. DOB on Refrigeration Cycle Air conditioners and refrigerators utilize the refrigerant cycle to operate. A liquid, freon, circulates within a closed loop, and is forced to evaporate and condense. Unfortunately, freon, along with other chlorofluorocarbon [CFC], have been discovered to cause ozone depletion if they are exposed to the air. Since the 1990's, freon has been phased out and substituted with hydrochlorofluorocarbons (HCFCs), where the ozone depleting effects are 10% of CFCs. It is extremely important to dispose of all old appliances which have refrigerants properly. Check with your local recycling centers.

The BiblioGov Project is an effort to expand awareness of the public documents and records of the U.S. Government via print publications. In broadening the public understanding of government and its work, an enlightened democracy can grow and prosper. Ranging from historic Congressional Bills to the most recent Budget of the United States Government, the BiblioGov Project spans a wealth of government information. These works are now made available through an environmentally friendly, print-on-demand basis, using only what is necessary to meet the required demands of an interested public. We invite you to learn of the records of the U.S. Government, heightening the knowledge and debate that can lead from such publications.
