We need you to answer this question! Refrigerant vapour in the purger is always expelled with the noncondensable gases. Excess refrigerant or excess high pressure will not effect an TXV or EXV enough to cause it to flood the evaporator. The system will become less efficient, and more … Refrigerant overcharging can also result in liquid refrigerant running too far into the evaporator coil, leading to a too-low suction side pressure and a reduction in cooling capacity In other cases overcharging with a refrigerant can lead to unexpected condensation or frosting on some of the system parts and components both in the air handler and in the compressor/condenser unit. Leo Suter Twitter, Of these, debris clogging or malfunctioning TXVs seem to be the most common problems. CAUTION: Overcharging air conditioning system will cause excessive head pressure. E46 Engine Bay Diagram, If an air conditioner is designed to work with 3 pounds of refrigerant but has 4 pounds in it, it’s pushing the system to work as if it were larger than it is. this website, certain cookies have already been set, which you may delete and Instead, you know that having too much refrigerant in the system can actually make the air hotter.
