New gas for car & home airconditioner

New gas for car & home airconditioner

An advice from all members. Would you give a try to what kind of car air conditioners refrigerant, he called NS-12 (fictitious name) which claims 20% -30% less power consumption, while improving efficiency by cooling the same percentage. The gas is equally appropriate and direct replacement for R12 and R134a systems.

Also an alternate for the substitution of refrigerant R-22 air conditioners to keep in house. This will carry the same benefits. Less energy needed better cooling efficiency. This may help to reduce electricity costs and better performance in summer AC peak to reach.

Note this is not a magic newest ultra gas or new invention. This is simply "oil" refrigerant in use for over 100 years, but was only allowed in industrial systems. However, recent law changes in Europe and Australia call reduction in global warming and ozone loss has allowed their use in household appliances. I have more detailed information for the technically inclined as they are interested.

As usual, there will be a number of advantages and disadvantages.

In the first place Disadvantages:

1. The gas is flammable at room temperature and pressure. By comparison, R134a is flammable under pressure with air / oxygen.

2. It requires a professional and personal safety equipment to operate in compliance with flammable nature of the substance. An open space is recommended.

3. May void the warranty for new vehicles.

Benefits Now

1. Consumes less power, while maintaining more cooling efficiency than R12 and R134a.

2. Does not decompose into toxic substances. For example, R134a in contact with hot engine easily decompose to extremely deadly hydrofluoric acid gas.

3. 30% cheaper than R12 and R134a.

4. Less power drain on the engine will reduce the loss of the pick-up especially in CNG cars.

5. High efficiency AC will improve performance on small cars such as the domestic Mehran, Adam, Alto, etc etc..

6. If a hydro-carbon, the "smooth" in nature. Reduced compressor internal friction which helps to prolong the life, noise and energy loss in the form of heat by friction is suppressed.

7. Does not react with water under heat and pressure to hydrofluoric acid acids that your air conditioning and internal corrosion can cause leaks in shape.

I am conducting this survey on someone else's name. Your opinion is wanted in relation to:

1. Use in your car?
2. Use your home AC?

There is a very good reason that HC refrigerants only be used in industrial applications. Allow me the opportunity to ensure the safety of HC refrigerants to clarify. Let's say you fill your car A / C up with propane instead of HFC134a and you get in a frontal collision. With HFC134a, the gas would simply evaporate into the atmosphere. HC refrigerant is a real chance of blowing up or burning feeling in your car. Worse, what would happen if the HC refrigerant leaks in the cabin while you smoke.

HC refrigerants are not used because they are not safe, R12 has been replaced because one CFCs and damage to the ozone layer. R134a is banned in Europe in all light vehicles in 2017, because the potential for global warming. Manufacturers are working on a new alternative, but do not expect miracles.

Here's what the EPA has to say about HC refrigerants.

A warning to consumers on Hydrocarbon Refrigerants
Common Sense to protect the environment without compromising security

(Lansdale, PA) 2005-04-25-vehicle manufacturers, suppliers of automotive components, the U.S. Environmental Protection Agency (EPA) and other organizations warn owners of cars and trucks on the use of flammable hydrocarbon refrigerants, which are traded to Avoid the Internet, at flea markets and swap markets, and in some supermarkets, but are not approved for this use. In the United States, it is illegal to
use of hydrocarbon refrigerants for CFC-12 used in cars manufactured before 1994 to replace. Hydrocarbon refrigerants used in newer vehicles designed for refrigerant HFC-
134a void the unit warranty and service technicians in jeopardy. Leaking air conditioning systems charged with hydrocarbons serious risks of fire or explosion under the hood or in the passenger compartment.

No offense but I do not understand what is the opportunity you have and what point you are trying to made in addition to the usual copy-paste information from the Internet. Have read and understand a thread before posting replies. I have all these risks, advantages and disadvantages in my post clearly. Your response is at best a partial detail of what is already posted. The flammability test is performed only at room temperature, pressure and oxygen concentrations as clearly stated above. All flammable refrigerants are to some degree under pressure with air / oxygen. Of course if one has to die from the cold poison, look no further than HFC gases. R134a AC leaking from your car will hydrofluoric acid gas back on contact with hot engine and can easily kill anyone who inhales example, the AC technician worked. Take a lesson in refrigeration and basic chemical principles to understand. Like many of copy-paste information is available on the internet to deceive people.

All refrigerants can kill people, either in the form of poisoning or explosions. For someone who is afraid this is just great, not against the air and the gas discharge Use your car's AC. Ammonia is used in commercial coolers, which again is extremely toxic. If safety is your concern, then a low pressure and small quantity requirements of HC makes them extremely secure than HFCs and HCFCs. An HC system load is less likely to explode and murder people versus HFC-based system. Note that AC is an exploding a bomb but independent of refrigerant used and HC-based system is less likely to explode due to their low pressure and cryogenic nature.

We had an internal split air conditioner charge of R290. These are not your typical LG, SG, Samsung, waves or Dawlence kind of toy units. This unit was a heavy Trane / American Standard brand and capacity of 2.5tons it was really brave.

I ran my car A / C charge R290 for a full year without any problems until I sold it. Yes, I have knowledge of the user that AC is filled with high-performance gas is highly flammable.

Regarding EPO, we all know how bureaucratic they are. People driving with CNG and LPG cylinders in their cars. In comparing the safety, your air conditioner have a very small size of the so-called "flammable" gas. LPG and CNG is continuously burned in the engine to create flames. Your air conditioning refrigerant is flammable even when pressure in a closed system in absence of air / oxygen.

I grew up playing with refrigeration and cooling system so please no comments monkey pasting information. I know what I'm talking about and take care to inform potential consumers.

All I want to know opinions from interested people willing to try one such product in your auto / air binnenlandse nadelen mits de veiligheid of all your concerns were met wetenschappelijke contested evidence. Any questions, post here.

Thank you!
