We’ll be glad to come out and take a look at the issue. 1431-183 A/C & Heating proudly serves Round …Low Load. While we often think of the combo of low suction, superheat, and head pressure as being caused by low airflow, it actually falls under a larger heading of low evaporator load. That simply means that the quantity of heat being picked up in the evaporator is lower than the refrigerant mass flow rate requires for the desired operation.im in the field 3 years now and this is the first time ive come across this. residential split system 1.5 tons and i had a good suction pressure but my head …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 R-410A system will be somewhere between 102 to 145 PSIG. If the system had R-22, the vapor pressure would be between 58 to 85 PSIG but these pressures will be dependent on ...Explore a comprehensive guide to troubleshooting low suction pressure and maintaining normal head pressure in HVAC systems.

Like the others have said so far. If the system has normal runs of refrigerant tubing and has proper refrigerant charge in it, if you have a liquid side restriction it would indeed show low suction and head pressures. high superheat and low/normal subcooling. Reply. 03-20-2012, 06:01 PM #14. MichaelPaladin.The fact that these readings are normal indicates the low suction pressure is not caused by low refrigerant, but insufficient heat getting to the evaporator. CAUSE …Low temp freezer running 404a. evaporator temp should be around -20 degrees - which is 15psi for 404a. (but it wont be quite that low until the box gets closer to proper temp. normal head pressure for 100 degree ambient would be 130 degree condensing temp which is 350 psi for 404a.R448a PT chart is quite useful in HVAC. It tells you what is the pressure of R488a liquid and vapor refrigerant from -49°F to 150°F.Inversely, you can also tell the temperature of R488a refrigerant if you know the pressures (from 0.7 psig to 462.8 psig).Further on, you will find an online R448a pressure temperature chart as well as a printable R448a PT …Number 2 is incorrect, metering device part depends on system to system. High load is correct. Look at your liquid line temps, subcooling and approach temps. They will help diagnose high head issues. There is another cause of high head pressure, mismatched (higher btu) compressor. Different refrigerant in the system.

404R pressure temperature chart is quite simple to understand. This is a table that tells you precisely what the pressure of R404A is at a certain temperature.

It has a piston as a metering device and compressor was running at 11.50 amps and RLA is 17.25 amps. Gonzo, if your evap was dirty you would have a low suction and low superheat. Not dirty evap let that go. High suction low head, with 100 lb suc and 100 degree ambient your head should be quite a bit higher. Really need the amp draw of comp and rated RLA but appears to be a compressor issue. lippert plant 119 The SC might be normal , but the normal head for a r410 system w/ a 68* ambient should be closer to 300psi and the normal suction press should be closer to 110psi w/70* IDB. Those p/t's sound more like r22. kdean1, buttwheat liked this post. As others have said it sounds like a TXV and maybe low on juice.In the cooling mode this will result in low suction pressure and low discharge pressure. Sub cooling would be extra high.
