What type of refrigerant for 2002 Subaru Outback?
Ozone friendly refrigerant HFC134a.....
What type of refrigerant for a 1997 Subaru Outback?
According to my repair manual the refrigerant is HFC134a.
Does the type of gas in an airsoft m4 affect the fps?
If you are talking about a gas blowback m4, then yes. Green Gas, Top Gas, and propane are all pretty much the same thing and will give you about the same fps. HFC134a (or you can use duster gas) is a much weaker gas, which might not even work in your gun because it might not have enough power to cycle the bolt. If it does work, HFC134a will give much lower fps.
What kind of freon is used in a refrigerator?
It's only Freon if it was manufactured by DuPont and sold under the name Freon - it's a trademark of theirs. Pure ammonia is still used in some industrial refrigerators. From the mid-1930s to the mid-1990s, R12 (CFC12) was used. Afterwards, R134a (HFC134a) was used in home refrigerators. Some newer units now use R600.
What is the advantange of hfc134a than other gas?
Its not a gas, perse (it is a vapor, but only until it gets to the condenser) Its the refridgerant we use in our cars Hydrofluorocarbon (HFC, R-134a) is not as harmful to the environment as the Clorofluorocarbon (CFC, R-12) we used to use--it has been banned in the EU past 2012 so there is going to be a new refridgerant coming out that is going to take R-134a off the market, just as with R-12
What are the advantages and disadvantages of using HFO-1234yf refrigerant in automobiles?
advantages: - Will help to reduce emissions of high Global Warming Potential Hydrofluorocarbon 134a refrigerant currently used in Mobile Air Conditioning Systems (MACS), due to the short atmospheric lifetime and extremely rapid breakdown of the gas in the environment; - (for DuPont and Honeywell shareholders) May yield windfall profits if policymakers are duped into believing that R-1234yf is a better solution than hydrocarbon refrigerants; - Should build greater acceptance of flammable refrigerants in MACS, and enable environmentally benign, highly effective, safe and cheaper natural hydrocarbon refrigerants to compete on a more level playing field. disadvantages: - Will be extremely expensive; -Is very complicated and energy intensive to produce, and is highly likely to be only produced by DuPont and Honeywell, who have made it very clear they expect to make substantial profits from the introduction of this gas; - Has unknown environmental impacts from degradation by-products, including Trifluoroacetic Acid (TFA), likely to include increasing toxicity in inland lakes, and a possible contribution to oceanic acidity levels; - When burnt, or exposed to heat, degrades into extremely toxic by-products of thermal decomposition, including hydrogen fluoride, lethal to humans at concentrations as small as 30ppm, and carbonyl halides, or phosgene, popularly known as nerve gas; - Is highly likely to result in severe injury and fatalities of vehicle occupants and emergency service workers from engine bay fires, and from anyone exposed to fumes from such fires that may occur in enclosed spaces such as underground carparks or tunnels; - When burnt, may also lead to the production of the very high GWP and extremely long lived greenhouse gas CF4; - Is providing a significant distraction from the availability of hydrocarbon refrigerants, by far the most suitable solution to the problem of high emissions of HFC134a.
How do you make dual magazines on a airsoft gun?
What to doHow to use a gas gun: Remove the magazine from the pistol by pushing on the magazine release. With the magazine removed: Fill the magazine, with the magazine below the gas canister As illustrated:Make sure the can is ALSO upside down. Make sure they are both perfectly in line and completely vertical. Do not tilt sideways at all or angle the green gas canister and the gun magazine. Make sure the nozzles get a firm seal, and proceed to fill the "Liquid" into the mag by pressing firmly down with the airsoft gas canister. Filling time depends on the mag capacity. A normal handgun mag is generally about 3 seconds. A 50-round mag is usually about 5-6 seconds. This will insure you get a full charge of gas, for the amount of BBs.After loading the green gas into the magazine, load the BB's. Simply pull down on the magazine follower and insert BB's as illustrated below Next, simply reinsert the magazine into the gun. After the gas has been loaded, magazine has been loaded with BBs, simply cock the gun as shown below and you're set to go:What NOT TO DO when filling the mag:If you fill the mag, and gas begins to spill, STOP. Let the magazine warm up at room temperature before attempting again. This is usually about 5-6 minutes. If you are able to form a tight seal and fill correctly, allow the magazine to warm to room temperature. Tapping the big metal button on the top, rear side of the mag will discharge the GAS from the gun magazine. Do NOT do this! It will prematurely wear out the seals and also cause the O-rings to freeze, damaging them permanently. Instead, fire the gun until out of gas. This is the safe way to discharge a gas-gun.Fire the gun in WARM weather. Using during the cold seasons are not advised. They will not cycle completely, fire well, and will use more gas than normal. Rapid-firing of the gas-gun will also cause the gun to freeze up, resulting in damage to the magazine or gun. These problems are not as prone during the hotter seasons or warmer weather.Use HIGH grade BBs for your guns. Lower quality BBs will tend to jam in the magazine well, preventing proper firing. Marui, Excel, Airsoft Elite, or AirSplat BBs are are highly recommended. These are all models which we carry, Airsoft BB. Using .12 is not advised for higher end airsoft guns, such as electric or gas will VOID THE WARRANTY and may cause permanent damage.Gas-gun care: Be sure to keep your slide and all moving parts lubricated with SILICONE oil which can be purchased on our website or at your local hardware store. Do not use anything else, such as petroleum based lubricants. ONLY 100% pure silicone oil is required. Other lubricants are not safe for use on plastic and rubber parts.Do not use Hoppes #9, WD-40, and other petroleum based lubricants will damage the guns permanently.Be sure to also spray silicone oil into the top nozzle of the magazine well every 5-6 magazines uses. This is done, by pressing the top release valve on the the mag while putting a quick spray of silicone into the top rubber exhaust valve. This will keep the seals and O-Rings properly lubed for a lifetime of use. For more details illustrations on how to maintain your gun, please refer to our Maintenance Guide.Recommended gases for gas airsoft guns:KWC: use HFC 22 or Green Gas only for these guns. Use with Red Gas will void the warrantyKSC/KWA: use HFC134a gas unless equipped with a metal slide. If equipped with metal slide upgrade use HFC 22 or Green Gas. Use with Red Gas will void warranty.Western Arms: HFC 134a gas is recommended. Use with any other gases (such as HFC22 or Green Gas) with void warranty.KJW, Y&P, STTI, HFC, other Taiwanese guns: HFC22 or Green Gas is recommended. Using HFC134a is not powerful enough. Use with Red Gas will void warranty.Maruzen, Marui: HFC 134a gas is recommended
