2 ton sanyo suction pressure erratic

Ac only systems suct pres climbs to 85 90 then slowly returns to a fluctuating 55 to 65 F server rm at 75 deg, evap blower blows cold but then ambient back to cool, the line length is about 75 ft, more than normal but went to 2 ton to prevent a shortened comp life . Ambient outside is 21 deg F . Could it be the compresser ( scroll ) HP bleeding ove ?

Your suction pressure is erratic, your max. pressure is to much high. You did not measure your unit current reading liquid line press. to complete the data. But the problem of your unit is not the compressor its the system. Try to reprocess the system flush the unit with nitrogen, isolate the capillary tube and flush it with nitrogen to insure that no restriction.

1.ton ac capillary pipe size and length I want to know. B coz suction line cooling level is very low gass psi 75


I'm guessing you should have 3/8 & 5/8 copper on that unit with a maximum of 50 feet. I doubt the line set size is affecting your pressures that significantly, you likely have a leak.

WHAT IS PSI SUCTION PRESSURE IN SPLIT AC WHEN UNIT IS IN OFF CONDITION


there is no suction at all when the machine is off as the gas equalizes around the system
all you will read is the pressure of the gas in the system and that will tell you nothing
to read gas pressures you need to know the type of gas in the system , have gauges that can handle the high pressures and have two on a manifold so that you can read suction and high side pressure differences
That way you can see if the system is low on gas or over charged

Engine light came on hooked up the digital OBD two car reader and it says PO 456


Code 456 is for a small leak found in the EVAP system. It could be a faulty gas cap, or something else.

I have some problem with our machine scotsman mv450 is to long product ice very slowly


Min freeze time 6 minutes and max freeze time 45 minutes. the 6 minutes is with perfect conditions. Example: Cycle time water temp was 50 degrees coming in to the water sump tray from water supply and the Ambient air temp surrounding the machine was a constant 70 deg than the machine should make ice every 10 - 12 minutes.now we know that the water temp from the water source is not going to be 50 deg and room temp will not be 70 deg all the time so the warmer water temp and ambient air temp is the longer it takes to make ice. one thing you wont to check is the water inlet valve to make sure it is not letting water seep through causing water temp not to cool down from running across evap plates. make sure the condenser coil is clean this will slow down production of ice.

How 2 add r22


The best way is weigh in a charge. of course the type of unit will come into play as split systems have enough refrigerant factory for up to 15 ft lineset or so, depending on units make etc. If a charge exists already and requires adjusting due to lineset length, or repairs etc, youcan simulate a 95 degree day ambient outdoors by restricting the air flow a bit to artificaially raise the head pressure as do low ambient controls, thus bringing the head to around 270lbs in a r 22 system or ambient plus 30 degrees , converted to prressure, so a 95 deg day plus 30=125 deg converted to pressure is 269 lbs, the indoor air temp being clse to 80 degreees helps, the indoor coil will be 40 degrees cooler than the indoor ambient if all is normal and design conditions are met by God or you. If the indoors 75, go to a 35 d
eg coil temp this is ball park, as the subcooling (15 deg)and superheat (10 at the evap coil, 20 at compressor) will need to be monitered along with amp draw and Delta T or temp differntials suply vs return.2_25_2012_2_55_05_am.png

On my 1996 ss impala what low side pressure should I see on the a/c with the system running


It all depends on the outside (ambient) air temperature. Your A/C low pressure switch is designed to turn the compressor off at 24 Psi. and turn it back on at 45 Psi. Most systems will normally run at between 25 and 40 Psi when the system is running on HIGH blower and "MAX" or "RECIRCULATE". A system that is fully charged may run at 25 Psi when the ambient temperature is 75 Deg. (F) and may run at 40 Psi when the ambient temperature is at 90 Deg. (F). (it can be even higher if ambient temperatures are higher than 90 Degrees.)

To properly diagnose a malfunctioning A/C system, the HIGH side pressure must also be checked. Restrictions in the system can make the low side pressure look normal while the high side pressure is high enough to blow hoses apart. (400+ Psi.)
