This air conditioning repair article series discusses the the diagnosis and correction of abnormal air conditioner refrigerant line pressures as a means for evaluating the condition of the air conditioner compressor motor, which in turn, is a step in how we evaluate and correct lost or reduced air conditioner cooling capacity. InspectAPedia tolerates no conflicts r410 suction pressure interest. We have no relationship with advertisers, products, or services discussed at this website, r410 suction pressure. Here are a few examples:.

Updated: Nov 20, It is important to know the range of these pressures in order to understand why and how charging and recovery are performed. Remember that temperature will affect the pressure of a refrigerant. If the air temperature surrounding the refrigerant increases, the refrigerant will absorb that heat and increase in temperature. This will cause the pressure of the refrigerant to rise. When an air conditioning system turns on, the large vapor line will lower in pressure while the small liquid line will rise in pressure. We will first examine the low-pressure side of the system, otherwise known as the vapor or suction line.

Although the A safety and training certification is not mandated by any government agency, there is a movement to certify as many installers and technicians as possible in an effort to improve the understanding and safe handling of this higher pressure refrigerant. Some manufacturers, contractors, and industry organizations seem to be "almost" requiring those who do business with them or work for them to become certified in the safe and proper use of RA. Although this particular certification is voluntary, failure to certify may cost contractors and technicians some lost business. The purpose of this article is to provide a brief overview of the essentials of working with RA. Those who have the time and opportunity to attend a RA certification seminar are encouraged to do so. Most of the seminars and published materials on this topic not only cover the specific differences necessary to the safe and proper handling of A, but they also review information that technicians should already know anyway. In this article only the essential differences between R usage and RA usage will be discussed. However, if a technician is going to take the voluntary A safety exam, he or she will be required to answer a number of general questions common to the function, operation, and servicing of all mechanical compression cooling systems. Every technician is expected to have a good solid knowledge of the complete mechanical cycle, superheat, subcooling, latent heats, and the major components of a system. A review of the basic system, accessories, and even global warming and ozone depletion is essential. Refrigerant A was developed to replace refrigerant 22 because R is being phased out due to its ozone depletion potential.

We will first examine the low-pressure side of the system, otherwise known as the vapor or suction line. During air conditioning mode, the pressure on the vapor line of an RA system will be somewhere between to PSIG. If the system had R, the vapor pressure would be between 58 to 85 PSIG but these pressures will be dependent on the wet bulb temperature inside the building and the ambient temperature outside the building.

This article refers to troubleshooting refrigerant charge on a and R22 residential air conditioning systems. Although many of the principles will carry over to other types of refrigerants and drop-ins. I will be sharing a pressure chart that may help you troubleshoot low pressure symptoms, high pressure symptoms. As well as other potential problems you may run into when trying to get your ra or r22 systems to normal operating pressures. I get asked this all the time. From my experience normal R22 pressures may be somewhere around 70psi for suction and psi for head pressure.

Errors The following errors occurred with your submission. If the refrigerant is added into the liquid line, the refrigerant will have to make its way through the metering device before it can enter the vapor line. POE oils are also irritating to the skin and a real medical concern if it comes in contact with your eyes. The liquid line on a running system will have a higher pressure than the pressure inside the recovery bottle as long as the recovery bottle does not have air, nitrogen, or a mix of multiple refrigerants inside. I do bakeries. Such should not be the practice on RA systems. It is imperative that only a metering device designed and properly sized for RA be used on a RA system. With all else being equal, it is possible to manufacture an RA air conditioning system that is physically smaller using less refrigerant and a smaller compressor than an R system of the same capacity and SEER rating. Remember that temperature will affect the pressure of a refrigerant. Some technicians have used lower temperature solders when making tubing connections on R systems. However, the technician needs to be able to check the charge while adding refrigerant in order to know how much to add unless they are charging by weight per foot of line set. But, your still running Suction which indicates a high evap load. This would allow for slow charging while the system is off.

Although the A safety and training certification is not mandated by any government agency, there is a movement to certify as many installers and technicians as possible in an effort to improve the understanding and safe handling of this higher pressure refrigerant.

But, your still running Suction which indicates a high evap load. There is a variety of POE oil types and grades; therefore, it is important to know which POE oil is in the system being serviced. It is imperative that only a metering device designed and properly sized for RA be used on a RA system. The scroll compressor has the advantage over the reciprocating compressor when comparing volumetric efficiencies and internal heat transfer losses between the suction and discharge ports. I noticed as ambient air got hotter head pressure will rise as well. A normally operating RA system with the same condensing temperature of degrees and a 45 degree evaporator saturation temperature will have a high side pressure of psig and a low side pressure of psig. Meanwhile, the National Park Service, administered by the U. It is even more important to use suitable brazing materials on RA systems. Want More? Looks sorry clean it. Recovery cylinders must be rated for RA use. Such a mistake could be the last one a technician makes.
