Description optional.One of the hottest discussions pardon the pun within the air conditioning and heating industry is the difference between two refrigerants — R and RA. Newer air conditioning models are designed to be used with RA for reliable and more efficient operation. Because RA can absorb and release more heat than R, your air conditioning compressor can run cooler, reducing the risk of compressor burnout due to overheating.

RA also functions at a higher pressure than R, so new compressors are built to withstand greater stresses, reducing the chance for cracking. If you were to put RA refrigerant into a system designed for R, the pressure would be too much and the unit would break.

All air conditioners use an oil to keep the compressor lubricated during operation. R air conditioners use mineral oil and RA systems use synthetic oil. The synthetic oil is generally more soluble with RA than mineral oil is with R This means the RA system operates more efficiently reducing wear and tear on the compressor.

Instead, a technician is required to come out to your home and install the R refrigerant. Like night and day! It is definitely a different operation as far as cooling.

Wish I had know about the AC77, which was never once mentioned by any of the many companies I spoke to about bidding the job. Like every other single thing is these current a-skewed days…. Your generation is too ignorant to realize how ignorant they are. The environment will be much better off when old farts like you disappear. I personally know of people in Arizona who have Puron systems and they need it serviced twice each year due to its high head pressure.

AC77 has nearly the same properties as R22 with the exception of non-depletion of the ozone layer. My house in MN has a heat. It uses r which is a prone. Oh no! I am so sorry to hear that about your R22 system dying.

Your email address will not be published. Notify me of follow-up comments via e-mail. There are two main categories of pressure controls - high pressure and low pressure.

These controls may be individual or combined into one control and are designed to protect the compressor. Skip to content. Quick and easy search: Search. Filter Audience Homeowners. Facility Managers.General household dehumidifiers and industrial refrigerated dehumidifiers need refrigerant to assist in operation.

Household dehumidifiers generally use refrigerant model: Ra, and industrial dehumidifiers generally use refrigerant model: R Performance and advantages and disadvantages. It has good comprehensive performance, making it a A very effective and safe alternative to R12 dichlorodifluoromethanewhich can be applied to most areas where R12 refrigerant is used.

Advantages: The refrigerant Ra is non-flammable, non-explosive, non-toxic, non-irritating, non-corrosive, and will not cause damage to the ozone layer. Not combustible in the air. Widely used in: refrigerator s, freezers, water dispensers, automobile air conditioners, central air conditioners, dehumidifiers, cold storage, commercial refrigeration, ice water machines, ice cream machines, refrigeration condensing units and other refrigeration equipment.

Disadvantages: However, because of its relatively high water solubility, it is not good for the refrigeration system. Even if there is a small amount of water, under the action of lubricating oil, it will produce acid, carbon dioxide or carbon monoxide, which will corrode the metal, or produce ' 'Copper plating' function, so Ra requires higher drying and cleaning of the system.

The properties and advantages of R22 R22 is a medium temperature refrigerant, its standard boiling point is Burning, non-explosive, non-corrosive. Disadvantages: R22 has strong penetrating ability, and leakage is difficult to find. Gases that have a destructive effect on the high-altitude ozone layer and the greenhouse effect.

We can provide small can,disposable cylinder, refillable cylinder,Ton cylinder and ISO tank.It is very difficult to choose a suitable refrigerant substitute. Many factors must be considered and a comprehensive evaluation must be carried out.

It should not only meet the requirements of ozone depleting potential value ODP and global warming potential value GWPbut also consider the thermal performance, toxicity, flammability, compatibility, investment and operating costs. The global warming potential GWP of Ra and R22 are and respectively, which belong to greenhouse gases.

The specific volume of Ra is 1. Ra has strong water absorption, which is 20 times higher than R Therefore, the dryer in the unit system is required to avoid ice blockage. Ra has stronger swelling effect on rubber than R22, and refrigerant leakage rate is higher in actual operation. In addition, the copper additive must be used in the copper plating process.

Ra system needs special compressor and special grease lubricating oil. Because of its high water absorption, high foaming and high diffusion, the stability of the system performance of the grease is inferior to that of the mineral oil used in R22 system.

The price of Ra and other HFCS refrigerant and its special lipid oil is higher than that of R22, so the operation and maintenance cost of the equipment is higher.

Comparing Refrigerants Side-by-Side

Although other HFCS refrigerants, such as RA, ra and RC, are better than Ra in efficiency, they also have some disadvantages, such as too high working pressure, high requirements on the adaptation and pressure resistance of pipeline components, the need to improve the design of heat exchanger and unit, and the investment, operation and maintenance cost, etc.

To sum up, ideal refrigerants do not exist in the short term. Compared with Ra environmental protection refrigerants, R22 refrigerants still have the advantages of high lsi20320ie firmware, stability and low cost in China. R22 refrigerants can still be consumed until before the ideal refrigerants are produced. Shanghai Branch: Address: No. Nanjing Branch Address: No. Toggle navigation.

High latent heat of vaporization is desirable in a refrigerant. It results in a high refrigerating effect and a low rate of refrigerant in circulation.

High suction gas density at the compressor suction means low sized compressor and a lesser-powered compressor motor. After the refrigerant passes through the evaporator, the refrigerant gas expansion is not very high, ie. Fluid to Gas expansion is low. This property of refrigerant provided a low compression ratio for the compressor, the higher mass flow rate of the refrigerant leading to a low rate of circulation within the system. Refrigerant must not be poisonous or lethal to air-conditioning, human health, and foodstuff.

When coming in contact with metal parts like piping and compressor must not cause any sort of electrochemical corrosion. Must be compatible with non-metallic parts such as nitrile rubber tubes, O-rings used for sealing purpose. As the refrigerant gets compressed under high pressure and temperature inside the compressor, it must not cause any explosion or catch fire within the system and continue its non-flammable properties. The presence of moisture in the system may cause the formation of highly corrosive compounds usual acids which may react with compressor lubricating oil and with other materials in the system including metals.

Moisture may cause the failure of compressor valves in case of hermetic compressor often causes breakdown of the motor winding insulation resulting in short-circuiting or grounding of the motor. The presence of moisture in lubricating oil may deteriorate properties of lubricating oil and formation of metallic or other sludge which may lead to clogging or chocking of valves, filters, and other oil passages. Moisture can enter into the system while charging of refrigerant, while repair ie.

When moisture is present in the form of water it may lead to icing within the evaporator coil and choking of the thermostatic expansion valve. Avoid moisture formation by connecting a filter drier which absorbs moisture from the refrigerant. It is the temperature above which the vapour refrigerant remains in the vapour state and cannot be liquefied back into its liquid state even after passing through the condenser or any cooling medium at any given pressure.

This happens only when the refrigerant temperature reaches beyond its critical temperature, ie. To be able to condense high-temperature vapour refrigerant into a liquid refrigerant by passing outside hot air in summer via a fan over condenser coils, the refrigerant must have high latent heat of vaporization.

R134a refrigerant is suitable for

The refrigerant used must be compatible and miscible means refrigerant can be easily separated with the compressor oil as there are greater chances of intermixing inside the compressor, wherein such condition following problems can occur:.It is now being used as a replacement for R CFC refrigerant in the area of centrifugal, rotary screw, scroll and reciprocating compresssors.

It is safe for normal handling as it is non-toxic, non-flammable and non-corrosive. Currently it is also being widely used in the air conditioning system in newer automotive vehicles.

The manufacturing industry use it in plastic foam blowing. Pharmaceuticals industry use it as a propellant. It exists in gas form when expose to the environment as the boiling temperature is Design changes to the condenser and evaporator need to be done to use this refrigerant. No Properties Ra 1 Boiling Point Detection of Leaks. When you suspect a leak of Ra in your air conditioning system, detection can be done by using one of the following 5 methods.
