can i use r22 evaporator coil to r410a

by Oda Zemlak Published 3 years ago Updated 2 years ago

Almost all new evaporator coils can be used with either an R-22 system or an R-410a system. They cannot, however, have been used with both types of gas: once you have released gas into the evaporator coil it becomes dedicated to that type of gas and cannot later be used with a different type of gas.

Can I use an R22 coil with R410A?

But remember, R-22 coils are typically tested to 300-400 PSI, which is a much higher pressure than R-410a will ever run on the low side. You should never use an R-22 evaporator coil with an R-410a outdoor unit if the outdoor unit is a HEAT PUMP. You should never reuse an R-22 evaporator coil if tin and antimony were used in the brazing process.

Can I replace R22 condenser unit with R410?

Asking as home warranty company tech wants to replace R22 complete condenser unit (locked compressor) with a R410 unit. I’ve heard R410 runs at much higher pressure than R22. Maybe to higher for R22 rated evaporator.

Does R410 run at higher pressure than R22?

What is the PSI of an R22 coil?

An R-22 evaporator coil operating in A/C mode, will run at approximately 70 PSI. An R-410a coil, conversely, at the same conditions will run at 130 PSI. Almost double the pressure.

Can I use a R-22 evaporator coil to R-410A?

You should never use an R-22 evaporator coil with an R-410a outdoor unit if the outdoor unit is a HEAT PUMP. You should never reuse an R-22 evaporator coil if tin and antimony were used in the brazing process.

Can you put a 410A condenser on a R-22 coil?

The answer is an undeniable and indisputable yes. Though you may hear several opinions to the contrary, we know from experience that it will cool equally as well as the old unit. When tuned properly, it will produce at least as cold of air as the R22 counter part being replaced.

Are evaporator coils interchangeable?

Most manufacturers specify that if you replace either the evaporator coil or condenser coil, it must be the same size (and SEER rating). Otherwise, they'll void any remaining time on the warranty. This is because manufacturers specifically design both coils to work synergistically.

Can I use R-22 Txv on 410A system?

The TXV determines which refrigerant can be used with a coil. Most new coils can be used with either R22 or R410A providing that the correct TXV is used. A TXV can also be added to a piston type coil to improve efficiency. This is a good idea when installing a new "dry R22 unit" on an existing system.

Are R22 coils still available?

In 2010, the U.S. stopped the sale of new air conditioning units that use R22. That means, new air conditioner in US manufactured after 2010 does not use R22 coolant. R22 phaseout in 2020 means that it became completely illegal to manufacture or import R22 itself into the country.

What is the replacement for R410A?

RS-53 (R470A) is a new non-flammable Drop-in replacement for R410A with a low Global Warming Potential (GWP) less than half that of R410A. RS-53 (R470A) has a similar thermodynamic performance to R410A with matching energy efficiency and cooling capacity.

What happens if evaporator coil is bigger than condenser?

Reduced Comfort The humidity and temperature of your living spaces can increase if your condenser and evaporator coils are not the same size. Your AC may excel in dehumidifying your home if the evaporator coils are larger, but will not cool your home effectively.

Can you mix match condenser and evaporator?

Your HVAC system's efficiency and lifespan will suffer. Mismatched parts will only result in headaches down the road, compromise your comfort and cause the system to fail shortly. The efficiency and lifespan of your equipment will suffer if the condenser and evaporator coils don't match.

Can you undersize a evaporator coil?

Undersized AC = uncontrolled RH If the evaporator coil isn't large enough, it can't pull out enough moisture from the air to get your humidity to the desired level.

What is the difference between R22 and 410a?

R410a is a hydro-fluorocarbon, which means it won't contribute to the depletion of our ozone layer. R22, in contrast, is a hydrochlorofluorocarbon, which means it will. Beyond being the more Earth-friendly option, R410a also performs better than its now-illegal counterpart.

Can you use 407c in a 410a system?

Will it work, yes.

How do I choose the right TXV?

When buying a standalone TXV, you have to choose one that is consistent with the cooling capacity of your system. The cooling capacity is a measure of your air conditioning system's ability to remove heat from the air in your home in a certain amount of time. The unit of measure for cooling capacity is tonnage.

Can you put a 2.5-ton condenser with a 2 ton coil?

In spite of the nay sayers here yes you can and it can work very well. You will indeed have to install an expansion valve that matches the condenser capacity. It also depends on the type of evaporator coil and furnace or Air Handler that you have.

Can I use a 3 ton condenser with a 3.5-ton coil?

There is some leeway, like a 3-ton condenser to a 3.5 air handler. The short answer is, you can't. A good tech might be able to get it to work with like a TXV, but you are going to be bottle-necked at the 3-ton. There is no way you will get 5-ton capacity after that.

How do I know what size evaporator coil I need?

If the evaporator must move 400 gallons per minute: 14 x 400 = 5,600. Multiply the answer by 500: 5,600 x 500 = 2,800,000. This answer is the evaporator's size, measured in BTUs per hour. Divide the answer by 12,000: 2,800,000 / 12,000 = 233.33.

Can you put a 4 ton condenser on a 3 ton coil?

she can not install a 4 ton condenser on a 3 ton coil and expect it to work. as far as everyone saying trying to force 4 tons of air through a 3 ton coil, he didn't say anything about changing the air handler out, only the outdoor unit. also the wiring probably isn't large enough to handle the larger unit.

What pressure is R22 coil?

The rated pressure for R22 systems was 300 psi. R410A systems are tested for 550psi. If the R22 coil was not rated for R410A, I would be cautious about using it even if the proper R410A metering device is used.

Why are 5 ton coils so big?

Most all 5 ton coils are significantly larger due to efficiency increases. You might be able to find a mobile home coil that could work. Your installer would have to check the various model dimensions and compatibility with the condenser you wish to use.

When will the R22 be removed from the market?

due to the fact that r22 is being removed from market in 2020 what will we be able to replace it with and will it require any changes to our ac?

Can you use a R22 condenser with a R410A?

I am sorry to say that there are almost no options to do what you describe. The are no longer any R22 condensers available. In order to convert the system to use an R410A condenser, the indoor coils and metering devices will have to be changed, in addition to flushing the refrigerant lines from inside to outside.

Can you mix R22 and R410A?

You can't mix R22 and R410a refrigerant . It will cause a black ash that will damage the compressor in the system. At a minimum you should replace the line set and the evaporator coil. Even if you did that, we would need to know the exact model numbers of the components you purchased in order to advise whether all of the system components are compatible with one another.

Can you convert R22 to R410A?

If you're going to convert from R22 to R410A refrigerant, the best thing to do would be to flush the lines you have, and put in units, an air handler and condenser that is meant to use R410A. R410A and R-22 are just so different that doing stuff like you want to do won't really work.

Can Brian change a Copeland compressor?

So, Brian has a Copeland CR28K6-PFV-230 compressor in the outdoor unit. So, can he just change the compressor? No. You can't do that. It probably wouldn't work. Even though you put a compressor in there that's R410A, the rest of condenser probably isn't tested and rated for operating at R410A pressures because R410A has to operate at a higher pressure. So, the coil is probably not tested for that and it would probably fail. I think you would need a different metering device too.

What is RCLB coil?

RCLB is an old cap tube coil. Not meant for the pressures of R410a. Not meant for the pressures of 13 SEER. Reusing that old think is ASKING for trouble. I wouldn't even put a 13 SEER dry 22 unit on it.

What to do if you change an R410?

If you change the outdoor unit to R410, you MUST replace the indoor coil with a matching coil.

What test is used to test refrigerant?

evacuates the refrigerant system properly and tests with a micron gauge and standing pressure test.

Is R-22 Dangerous?

R-22 refrigerant has been proven to cause damage to our planet’s ozone, contributing to global warming. As of 2010, manufacturers stopped producing R-22 refrigerant and air conditioning units designed to use this refrigerant system. However, good news came from it. The new air conditioners now use R-410A refrigerant which is much more energy efficient and doesn’t impact the ozone as much. However, many people can’t replace their air conditioner unit even though they may want to. Often they will look for another option. One option is to retrofit your R-22 refrigerant system with a R-410a refrigerant system. However, this isn’t the easiest task nor is it as cheap as many may have hoped. Retrofitting a refrigerant system can be expensive, which is why it is often encouraged to replace the air conditioner instead as it may be a wiser investment in the long run. But, for those who want to consider the retrofitting option, this is how it can be done.

How far should a refrigerant line be?

For the R-410A refrigerant system, the line must be between 25 to 50 feet in total distance. Additionally, the line must be flushed and cleaned out.

What is R-22 refrigerant?

R-22 refrigerant leaves behind a mineral oil and other contaminants. The entire system must be cleaned and this will include the filter driers, the condenser, and evaporator. Essentially, all of the components the refrigerant travels through will need to be flushed and cleaned.

Does an air conditioner run on R-22?

Uncategorized No Comments. Many homeowners that learn their air conditioner runs on R-22 refrigerant fears the day their unit develops a refrigerant leak. R-22 has been phased out and new air conditioners run on the new R-410A refrigerant which is much more environmentally friendly.

How does an evaporative condenser work?from sciencedirect.com

In large systems, evaporative condensers are utilized combining airflow with water. The refrigerant is condensed by using a combination of airflow and water sprayed onto a coil, usually in a tower. The water is then collected in a sump and pumped back to the sprayer.

How much carbon dioxide is in a boiler?from sciencedirect.com

The heat of the boiler produces 0.79 ppm of carbon dioxide for each ppm of sodium bicarbonate in the feedwater and 0.35 ppm of carbon dioxide from each 1 ppm of sodium carbonate (as CaCO 3) in the feedwater.

How does oxygen enter a boiler?from sciencedirect.com

Oxygen can enter the condensate system via incomplete deaeration of the boiler feedwater or through leakage of seals in condensate pumps. Pressure changes from intermittent operation of boiler systems also tend to pull oxygen into the pipes.

Why is it important to maintain the cleanliness of the internal boiler surfaces?from sciencedirect.com

Experience has indicated that, to maintain the cleanliness of the internal boiler surfaces, careful attention must be given to protection of the feed and condensate systems from oxygen attack during storage. Boiler plant that is idle, even for short periods (e.g. weekends), is susceptible to attack. Boilers that see incompletely deaerated water during start-up and during their removal from service can become badly fouled, or even corroded.

How does a water pump work?from sciencedirect.com

In evaporative condensers, a circulating water pump draws water from a pan at the base of the condenser and sprays the water onto the coils. In addition, a large amount of air is drawn over the condenser coils. Evaporation of water requires latent heat, which is extracted from the refrigerant.

How to get the highest resolution?from sciencedirect.com

Highest resolution is obtained if the size of the condenser aperture is matched to the size of the objective’s back aperture. An optimum image is reached by balancing the resolution versus contrast and depth of field by closing the aperture diaphragm only as little as needed for sufficient contrast. This setting which is different for each objective depends on what information one needs to obtain from the observed specimen. See example at: http://www.olympusmicro.com/primer/java/kohler/contrast/index.html.
