Condenser coil on the high side, as in the liquid line, which connects the condenser metering device. Refrigerant enters the dispenser at high pressure and temperature, but leaves at low pressure and temperature. The entrance dispenser on the high side, but the outlet is on the lower side of the system.Click to see full answer. Considering this, what is the low side of a refrigeration system?The low side of a refrigeration system usually houses the evaporator, suction line, and any accessory components located within the suction line. Accessory components can include evaporator pressure regulator valves, suction filters and driers, crankcase pressure regulator valves, and suction accumulators.Subsequently, question is, do you add refrigerant to the high or low side? The freon is added on the LOW PRESSURE SIDE ONLY. The hose tool you bought is made so you can only hook to the low side as the high side and low side fittings are different sizes and shapes for SAFETY’S SAKE. Hereof, is the suction line the high side? The low side, or suction line, will be the line connected to the compressor from the top or higher position.What is high side HVAC?High side and low side refer to the pressures in the two halves of the system. The high pressure side is the discharge side. It runs from the compressor outlet to the meterin device inlet. The low pressure side is the vaccum side. It runs from the metering device outlet to the compressor inlet.
