What component helps in measuring the pressure of refrigerants in a system?

A manifold gauge is an essential tool used in the HVAC industry to measure the pressure of refrigerants in a system. It consists of two gauges: one that monitors the low-side (suction) pressure and another that measures the high-side (discharge) pressure. By accurately displaying the pressure readings, the manifold gauge allows technicians to assess the system's operational health, determine refrigerant charge levels, and identify issues such as leaks or blockages.

This tool is crucial for troubleshooting and maintaining the efficiency of refrigeration and air conditioning systems. It provides the necessary data for performing tasks such as recharging the system with refrigerant or diagnosing performance problems, which can directly impact system efficiency and longevity. Understanding the pressures in the system is vital for ensuring optimal operation and performance of the HVAC equipment.
