Technicians with R-22 experience will need to become familiar with working with high and low side pressures that are much higher when using R-410A. A typical R-22 system operating normally with a head pressure of 260 psig at a 120-degree condensing temperature and a low side pressure of 76 psig at a 45-degree evaporator. From my understanding the small copper tube is the high pressure side with Freon that has been compressed to a liquid. When this liquid is allowed to boil in the inside evaporator things cool down. Conversely the large copper pipe is the return line from the evaporator sometimes referred to as the suction line or low pressure side. Normally, the high side (liquid) line is thinner than the low side (suction) line and is very hot. The low side tends to be thicker and is cold. People often get them reversed, thinking the hot line must be coming from the evaporator and is hot because heat from the cabin has transferred to it. In fact, the opposite is true. The high side line. This is the refrigeration effect taking place and the drier and liquid line can even get cold enough to allow frost to form. If the liquid line feeding the filter/drier is 105 °F and the shell of the filter/drier cold to the touch, the high side restriction will be obvious.

If allowed to operate in this condition for too long, liquid refrigerant can make its way back to the compressor. If this happens, the compressor can be damaged. It should also be noted. Once the refrigerant level drops too low, the system stops working. So this problem only occurs in a "sweet spot", where the refrigerant is low, but not too low. The high side of the A/C refrigeration system is the discharge line. Here the gas refrigerant enters and then gets out in the liquid form. Then it travels to the suction line or the low side. Should Suction Lines Be Hot? No, the suction lines should not be hot. It is the low-pressure side that has a lower temperature.. Answer (1 of 3): Any number of causes. High head pressure often indicates insufficient condensing effect, which could be a dirty condensing coil, slowed or disabled condensing fan or too high a condenser water temperature if a water-cooled system. Low suction pressure is usually do to insufficie. The Refrigerant Pump-Down Method. Yes, this is in fact, true and it's called the refrigerant pump-down method. Whenever a new condensing unit is purchased it is pre-charged at the factory with refrigerant. Most are precharged for a line set up to 25 feet. The refrigerant is released by opening two valves, one for the liquid line (liquid line. The Kwik Charge charging unit accepts liquid refrigerant from the cylinder and discharges into low side of the system. Charging rate is up to eight times faster than vapor charging. In addition, liquid charging is required when using R-410A and other blended refrigerants. Attach the Kwik Charge device to the low side of the charging manifold. When the engine is on and the AC is on high, low pressure readings should be around 30 psi and the high pressure side should be about 250 psi depending on your car. The correct reading will display once the clutch engages and the gauge stops cycling. A high-side float does prevent blow-through of unevaporated liquid, but it is unable to modulate the liquid flow rate, and generally moves back and forth from the fully closed to the fully open position. ... Suction/liquid line heat exchangers subcool the liquid refrigerant leaving the condenser by heating the vapour leaving the evaporator. Possible side effects of liquid magnesium include the following.
