A blockage causes high head pressure while suction pressure remains low. This imbalance puts strain on the compressor and reduces cooling efficiency. To troubleshoot, technicians will check for dirty filters, malfunctioning expansion valves, and debris in condenser coils. Clearing these blockages restores proper function to the refrigeration cycle.High Head Pressure, Normal Suction Pressure . High Head Pressure, Normal Suction Pressure is a common problem that can occur in an air conditioning system. It occurs when the compressor’s condensing unit has difficulty turning the refrigerant from gas to liquid because of high outside temperatures or inadequate airflow through the outdoor coil.A normal blood pressure range, according to WebMD, occurs when the systolic number is 120 or below and the diastolic number is 80 or below. High and low blood pressure problems aff...

Flights to so...The low-side pressure of an A/C system at 70 deg ambient temperature will be 35-40 psi ; R-22 Low-Side Typical Operating Pressure-Range = 58 - 85 psig Varies by indoor wet bulb temperature and outdoor ambient temperature, where higher heat loads increase the vapor line pressure. Other sources give the low side pressure range = 60 - 80 psig. I have a suction pressure of 70, converted temp of 41, suction line temp of 51, head pressure of 250, converted temp of 117, head line temp of 96. Air entering condenser is 82 and exit is 100. Air entering evaporator is 76 and exiting is 52.

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. The high side pressure, in contrast, refers to the refrigerant pressure in the discharge line. This is basically the pressure after the compressor. Even though the ideal pressure range for an R-401A air conditioner falls in the range of 110-140, its low side pressure should not be less than 100 psi, nor should it be more than 160 psi. Why this ... ….

Lower than normal, higher than normal. It is desirable for refrigerant in the suction line tube to be slightly superheated in order to. Insure liquid refrigerant does not enter the compressor.

code p0420 dodge ram 1500 How to Check Subcooling. Attach the thermometer to the liquid line. This time, near the condenser. Then take the head pressure in Psi and convert it to the temperature on the pressure/temperature chart. Assuming you are dealing with a R22 system, let’s say the head pressure is 260Psi. This will convert to 120F. bagel bakery monticellods arms inc Over time, your vehicle's air-conditioning system may leak out enough freon to require a recharge.

I checked evap coil and filter and both were clean, so I figured it was low on R22. I added 7 lbs. (factory charge is 7.25 lbs) and pressures did not change. The suction line is frosting up to the compressor. I'm starting to think I have a bad reversing valve.The compressor is still cooling, but not to its rated capacity, which can cause refrigerated products to spoil faster and frozen products to begin to thaw.
