Refrigerant is not used for pressure testing because it is a specialized fluid used for cooling and is not an ideal medium for detecting leaks in a system. Refrigerant can be harmful to the environment if it leaks out, so using a different type of fluid, such as nitrogen or a specific leak detection solution, is preferred for pressure testing purposes.
Refrigerant is not used to pressurize a system for a standing pressure test because it is a volatile substance, which can pose safety risks at high pressures. In addition, refrigerant can leak easily through seals or connections, which can compromise the effectiveness of the pressure test. Instead, inert gases such as nitrogen are typically used for pressurizing systems during pressure tests.
The critical pressure of a refrigerant is the pressure at which the liquid and vapor phases of the refrigerant become indistinguishable at the critical point. Beyond this pressure, any increase in pressure will not result in liquefaction of the vapor. The critical pressure is an important parameter used in refrigeration systems to determine conditions for efficient operation.
A pressure sensor or transducer is used to measure the pressure of the refrigerant in a sealed system, which in turn is correlated with the temperature of the system. As temperature increases, the pressure of the refrigerant also increases, allowing the system to sense temperature changes and adjust accordingly.
The function of the condenser is to release heat from the refrigerant, causing it to condense from a gas to a liquid state. This process increases the pressure of the refrigerant.
Refrigerant pressure decreases in a refrigerant cylinder while charging with vapor because vapor has a lower density compared to liquid refrigerant. As vapor is introduced into the cylinder, it displaces the liquid refrigerant, causing the pressure to drop as the overall density of the refrigerant in the cylinder decreases.

This requires knowing type of refrigerant and temperatures the system is running at. The test or work book will have all this info so you can work it out.

As temperature increases, the pressure of the refrigerant also increases, allowing the system to sense temperature changes and adjust accordingly.
The refrigerant cylinder pressure is typically higher than the system pressure, which allows the refrigerant to flow from the cylinder into the system. By opening the valve on the refrigerant cylinder, the higher pressure inside the cylinder forces the vapor refrigerant into the lower pressure system. This creates a flow of refrigerant into the system until the pressures equalize or until the desired amount of refrigerant has been added.
You cool it and run it through a metering devise.
If your talking about an Orifice tube?, It is used to convert high pressure refrigerant to low pressure refrigerant which then enters the evaporator. As the blower motor pushes warm air thru the evaporator, the refrigerant turns from a liquid to a gas which cools the air.
The pressure and the specific refrigerant properties determine the temperature at which a refrigerant vaporizes. As pressure increases, the boiling point of the refrigerant also increases. Different refrigerants have different boiling points at different pressures.
