it depends on the surrounding air temp you need a pt chart for example at 90 degrees the standing pressure would be 105 psig

In the low-pressure side of the system, R134a is a gas with low temperature and pressure, typically around 30 psi. In the high-pressure side, R134a is a high-temperature, high-pressure gas, usually around 250-350 psi. These two systems work together to transfer heat from the inside of the vehicle to the outside, providing cooling.

R134a high and low pressure readings?

For a home air conditioning unit 35 psig low and 125 - 150 psig high (depending on outdoor temp) are desirable.


Which is warmer the high pressure system or the low pressure system?

The high pressure system is warmer then the low pressure system . simple reason pressure is high when the molecules of gas are vibrating more violently then they do in normal routine ( vibrations of molecules can only be increased by increased temperature) hence if the pressure is high the temp will always be warmer then in low pressure area .


What happens when a high pressure system moves in where a low pressure system already is?

When a high pressure system moves into an area where a low pressure system already exists, it typically brings clearer skies, calmer weather, and cooler temperatures. The high pressure system will suppress the vertical movement of air associated with the low pressure system, leading to improved conditions.


How air moves differently in low- and high-pressure system?

a high pressure system moves clockwise, while a low one moves counter clockwise. high pressure systems move down and out, and low pressure systems move in and up.
