A chemical characteristics the chemical characteristics of r410a are similar to those of r22 in that both are chemically stable non flammable refrigerants with low toxicity however just like r22 the specific gravity of r410a gas is heavier than that of air because of this it can cause an oxygen deficiency if it leaks into a closed room since it collects in the lower area of the room it also generates toxic gas when it is directly exposed to a flame so it must be used in a well ventilated environment where it will not collect 55
About r410a refrigerant 55
B compositional change pseudo azeotropic characteristics r410a is a pseudo azeotropic mixture comprising the two components r32 and r125 multi component refrigerants with these chemical characteristics exhibit little compositional change even from phase changes due to vaporization or condensation which means that there is little change in the circulating refrigerant composition even when the refrigerant leaks from the gaseous section of the piping accordingly r410a can be handled in almost the same manner as the single component refrigerant r22 however when charging because there is a slight change in composition between the gas phase and the liquid phase inside a cylinder or other container charging should basically begin with the liquid side 55
C pressure characteristics as seen in table 2 the gas pressure of r410a is approximately 1 times as high as that of r22 at the same refrigerant temperature which means that special r410a tools and materials with high pressure specifications must be used for all refrigerant piping work and servicing 55
Converting air conditioners to r410a since it was declared in1974 that chlorofluorocarbons cfc hydro chlorofluorocarbons hcfc and other substances pose a destructive danger to the ozone layer in the earth s upper stratosphere 20 to 40 km above the earth measures have been taken around the world to prevent this destruction the r22 refrigerant which has conventionally been used in acs is an hcfc refrigerant and therefore possesses this ozone destroying potential international regulations the montreal protocol on ozone damaging substances and the domestic laws of various countries call for the early substitution of r22 by a refrigerant which will not harm the ozone layer 55
In acs the hfc refrigerant which has become the mainstream alternative is called r410a compared with r22 the pressure of r410a is approximately 1 times as high at the same refrigerant temperature but the energy efficiency is about the same consisting of hydrogen h fluorine f and carbon c r410a is an hfc refrigerant another typical hfc refrigerant is r407c while the energy efficiency of r407c is somewhat inferior to that of r410a it offers the advantage of having pressure characteristics which are about the same as those of r22 and is used mainly in packaged acs 55
Installation and servicing air conditioner using r410a 55
Outline 55
The characteristics of hfc r410a refrigerants 55
1 always replace the dryer of the outdoor unit at the same time the replacement dryer is wrapped in a vacuum pack replace it last among the refrigerating cycle parts start brazing as soon as you have opened the vacuum pack and begin the vacuuming operation within 2 hours 56
1 you can use the conventional r22 flaring tool if you need to buy a new tool buy the r410a type 56
2 use when it is necessary to detect small gas leaks 56
After finishing the installation check to make sure there is no refrigerant gas leaking 56
Cause the gas pressure of r410a is approximately 1 times as high as that of r22 a mistake in installation or servicing could result in a major accident it is essential that you use r410a tools and materials and that you observe the following precautions to ensure safety 56
D r410a refrigerating machine oil conventionally mineral oil or a synthetic oil such as alkylbenzene has been used for r22 refrigerating machine oil because of the poor compatibility between r410a and conventional oils like mineral oil however there is a tendency for the refrigerating machine oil to collect in the refrigerating cycle for this reason polyester and other synthetic oils which have a high compatibility with r410a are used as refrigerating machine oil because of the high hygroscopic property of synthetic oil more care must be taken in its handling than was necessary with conventional refrigerating machine oils also these synthetic oils will degrade if mixed with mineral oil or alkylbenzene causing clogging in capillary tubes or compressor malfunction do not mix them under any circumstances 56
Do not perform any alterations on the ac unit under any circumstances have all repair work done by a specialist incorrect repairs can result in a water leakage electric shock fire etc 56
Do not use any refrigerant other than r410a in acs that have been used with r410a 56
For other installation work you should have the usual tools such as screwdrivers a metal cutting saw an electrical drill a hole core drill 65 or 70 dia a tape measure a level a thermometer a clamp meter an insulation tester a voltmeter etc 56
If any refrigerant gas leaks while you are working ventilate the room toxic gas may be generated if refrigerant gas is exposed to a direct flame 56
In order to prevent an r410a ac from mistakenly being charged with any other refrigerant the diameter of the 3 way valve service port on the outdoor unit has been changed also to increase its ability to withstand pressure the opposing dimensions have been changed for the refrigerant pipe flaring size and flare nut accordingly when installing or servicing refrigerant piping you must have both the r410a and ordinary tools listed below 56
Necessary tools 56
Safety measures when installing servicing refrigerant piping 56
Tools for installing servicing refrigerant piping 56
When installing or transferring an ac do not allow any air or substance other than r410a to mix into the refrigeration cycle if it does the pressure in the refrigeration cycle can become abnormally high possibly causing an explosion and or injury 56
When installing or transferring an ac follow the instructions in the installation instructions carefully incorrect installation can result in an abnormal refrigeration cycle or water leakage electric shock fire etc 56
Because the pressure is higher for the r410a type the conventional type cannot be used 57
Copper tube gauge for clearance adjustment used when flaring with the conventional flaring tool clutch type 57
Flaring tool clutch type 57
In the r410a flaring tool the receiving hole for the clamp bar is enlarged so the clearance from the clamp bar can be set to 0 0 mm and the spring inside the tool is strengthened to increase the strength of the pipe expanding torque this flaring tools can also be used with r22 piping so we recommend that you select it if you are buying a new flaring tool 57
Manifold gauge 57
R410a tools 57
The shape of the manifold ports has been changed to prevent the possibility of mistakenly charging with another type of refrigerant 57
This gauge makes it easy to set the clearance for the copper tube to 1 1 mm from the clamp bar of the flaring tool 57

Piping materials 60
Processing and connecting piping materials 60
Refrigerant piping work 60
A check to make sure there is no scratches dust etc on the flare and union 61
B align the flared surface with the axial center of the union 61
C use a torque wrench and tighten to the specified torque the tightening torque for r410a is the same as the conventional torque value for r22 be careful because if the torque is too weak it may lead to a gas leak if it is too strong it may split the flare nut or make it impossible to remove the flare nut 61
