Read the charging chart specific to the unit. Not all 410A machines will operate at identical pressures in identical conditions.
...It will be what ever your suction pressure is.
The low pressure port (Suction) and the high pressure port (Discharge) are both located on the back side of the compressor.
The suction line will be the larger line going into the compressor.
To prove a bad suction reed in a compressor, you would need to do a pressure test. You can isolate the compressor and check for pressure drop in the suction line. A significant pressure drop would indicate a faulty suction reed. Additionally, you can inspect the reed valve for visible signs of damage or wear.
The proper suction pressure of any air conditioning or refrigeration system is determined by the type of refrigerant used and sometimes the amount of charge. : Suction pressure used is also directly related to the temperature required. : The temperature required in the evaporator relates to the pressure required in the suction line since, the fluid is at saturation in the evaporator. : Knowing the temperature required, use the fluid's saturation tables to find the corresponding pressure required.
These are terms used by refrigeration and air conditioning techs. The suction is refrigerant returning to the compressor from the evaporator, or the low side. The high side is the discharge or head pressure, where high temperature high pressure gas leaves the compressor to flow into the condenser. These systems should only be worked on by licensed and experienced techs.
AC discharge and suction lines are components of an air conditioning system. The discharge line carries high-pressure refrigerant gas from the compressor to the condenser, where it releases heat and condenses into a liquid. In contrast, the suction line transports low-pressure refrigerant gas from the evaporator back to the compressor, where it is compressed and cycled again. Proper insulation and maintenance of these lines are crucial for efficient system performance.
The suction differential pressure (DP) of a rotary screw compressor refers to the pressure difference between the inlet and outlet of the compressor's suction side. It is an important parameter that indicates the efficiency of the compressor's operation and helps assess the performance of the system. A higher suction DP can indicate potential issues, such as increased resistance or blockages in the intake line, which can affect the compressor's capacity and energy consumption. Monitoring suction DP helps in optimizing the compressor's performance and ensuring reliable operation.
High gas suction pressure in a gas compressor can lead to increased power consumption, reduced compressor efficiency, and potential damage to the compressor components due to excessive load. It can also result in higher discharge temperatures and potential overheating of the compressor.
The AC Compressor will kick on and off to maintain approx 32 psi on the suction side of your Air Conditioning system. This creates a continuous cycle of Freon which will change from a Liquid on the suction side into a Gas on the Pressure side. During this exchange from Liquid to Gas cold air is created to cool your space.
The suction line connects the evaporator outlet and the compressor intlet. Low pressure refrigerator vapour is drawn from the evaporator to the compressor through this line.
At very low suction pressure, the suction valves of reciprocating compressor will not work and there will be no gas in the cylinder during compression stroke, resulting some damage to the suction valves. If low suction pressure trip protection is not provided there can be some abnormal damage.
