The refrigerant pressure on an ice machine using R-404A refrigerant should typically be around 175-250 psi on the low side and 250-350 psi on the high side, depending on factors such as ambient temperature and load conditions. It's important to consult the manufacturer's specifications and guidelines for the specific ice machine model to ensure proper operation.

How is the refrigerant cylinder pressure kept above the system pressure when a system is being charged with vapor from a cylinder?

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.


Why is refrigerant not used for pressure test?

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.


What are the suction and discharge pressures of cold room using R410a refrigerant?

The suction pressure for a cold room using R410a refrigerant typically ranges from 60-70 psi, while the discharge pressure is around 250-300 psi. These values may vary depending on factors such as ambient temperature and the specific operating conditions of the system.


How do you charge a semi hermetic compressor?

To charge a semi-hermetic compressor with refrigerant, you will need to connect a refrigerant cylinder to the system using proper hoses and gauges. Then, you will slowly introduce the refrigerant into the system while monitoring the system pressure and temperature. It is important to follow the manufacturer's guidelines and recommendations for the specific type of refrigerant and the correct amount to be added.


How do you charge a refrigerator using a sight glass?

To charge a refrigerator using a sight glass, you need to monitor the refrigerant flow while adding more refrigerant until the sight glass indicates a clear, bubble-free flow. This ensures that the system is adequately charged with refrigerant. Make sure to follow manufacturer instructions and industry best practices when charging the refrigerator.

How can R-12 refrigerant be identified in a recovery cylinder?

R-12 refrigerant can be identified in a recovery cylinder by its unique chemical properties and color. R-12 refrigerant is a chlorofluorocarbon (CFC) with a pale yellow color. It can also be confirmed using a refrigerant identifier tool that can detect the specific type of refrigerant present in the cylinder.


To maintain 40 degree evaporator coil temperature what is the suction pressure?

The suction pressure required to maintain a 40 degree evaporator coil temperature depends on the refrigerant being used, as different refrigerants have different pressure-temperature characteristics. A typical range for R-22 refrigerant would be around 55-60 psig. It is important to consult the specific pressure-temperature chart for the refrigerant being used.
