On a 90 degree day, the approximate pressure of an air conditioner unit can vary depending on factors such as the efficiency of the unit, the refrigerant used, and the specific operating conditions. However, typical operating pressures for a residential air conditioner on a hot day could range from 200 to 300 pounds per square inch (psi) on the high side and 60 to 80 psi on the low side.

Without knowledge of the pressure in the air cond. lab. unit you will not be able to calculate the mass flow. Without the mass flow you cannot do any analysis of the system.

The suction pressure of an R22 unit on an 83-degree day will vary depending on factors such as indoor temperature, coil condition, and humidity levels. A typical range for suction pressure on an R22 unit could be around 60-70 psi on an 83-degree day. It's important to refer to manufacturer specifications and consider other system parameters for an accurate assessment.

The pressure of an AC unit on a 90 degree day can vary depending on factors such as the specific unit, its operating conditions, and any potential issues with the system. Generally, the pressure in an AC unit would typically be higher on a hot day due to increased demand for cooling, but it would be best to consult with a professional HVAC technician for an accurate assessment.
Overcharging an air conditioning unit with freon can cause the head pressure to increase beyond recommended levels. This can lead to system malfunctions, reduced cooling efficiency, and potential damage to the compressor. Regular maintenance and proper refrigerant levels are crucial to ensure the optimal performance of the unit.
