No, you cannot directly replace R404A with R134A, as they have different properties and applications. R404A is a blend designed for low-temperature refrigeration, while R134A is typically used in medium-temperature applications, such as automotive air conditioning. Using R134A in a system designed for R404A could lead to inefficiency, inadequate cooling, and potential damage to the system. Always consult with a professional technician before making refrigerant changes.
To charge a walk-in cooler with R404a refrigerant, you will need to connect a refrigerant cylinder to the system using a manifold gauge set. Open the cylinder valve and slowly add the necessary amount of refrigerant into the system according to the manufacturer's specifications. Be sure to monitor the system pressures and temperatures as you charge it to ensure that it is properly charged.

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 refrigerant cylinder pressure is kept above the system pressure by regulating the flow of refrigerant from the cylinder into the system. This is typically achieved using a charging hose with a metering device or valve that controls the rate of flow. By adjusting the flow rate, the pressure in the cylinder can be maintained higher than the system pressure during charging.
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.
