1. High Subcooling and High Superheat: Symptoms: If both subcooling and superheat are high the system is experiencing a high side restriction. These restrictions can form in the filter drier, solenoid valve or metering device. High subcooling suggests that too much refrigerant is being condensed due to restriction holding refrigerant back in the condenser, while high superheat indicates that.

4 Fluke Corporation Troubleshooting HVAC/R systems using refrigerant superheat and subcooling Measuring liquid line temperature with a DMM and a pipe clamp. Note: Condensing temperature is derived from using the PT chart. On new refrigerant blends with high temperature glide, this is called the bubble point (BP) temperature. See Figure 2. Figure 5.

The refrigeration system must also reject superheat as well as the load heat from the evaporator. As part of the refrigeration cycle, the system also condenses the refrigerant. This process involves taking a vapor, removing the heat outside, and condensing it into a liquid by removing the heat and returning it to its condensing temperature.

Manufacturers of refrigerants, controls, and other suppliers distribute hundreds of thousands of pressure-temperature charts to the trade every year. It would be rare indeed to find service technicians who could not put their hands on a pressure-temperature (P-T) card at a minute's notice. In spite of the widespread availability and apparent reference to the pressure-temperature relationship.

Systems set at 350 CFM per ton or less are more common today than ever, especially in humid climates. In those cases, the above chart won't apply, and the delta T will be higher. Diagnosing With The Five Pillars This list must be utilized by taking all five calculations and matching up the potential problems until you find the most likely ones.

The only difference is air uses a fan, and fluid uses a pump. We must ensure we have the correct air flow or fluid flow before the next step of troubleshooting can take place. Ensure the fan or pump is powered, running and, most importantly, rotating in the correct direction. Make sure air filters and inline strainers are clean.

Here's a step-by-step guide on how to read a refrigerant P-H chart: 1. Understand the axes: The P-H chart typically has the pressure (P) axis on the y-axis and the enthalpy (H) axis on the x-axis. The pressure is usually measured in units like psi, kPa, or bar, while the enthalpy is measured in units like Btu/lb, kJ/kg, or kcal/kg.

Why Are PT Charts Essential? Refrigerant PT charts are indispensable for several reasons: System Troubleshooting: HVAC technicians use PT charts to diagnose issues with cooling systems. By measuring the pressure and temperature at various points in the system, they can pinpoint problems like refrigerant leaks, blockages, or inefficient operation.

Its a refrigerant to oil charge limit for manufactures. The more refrigerant and the less oil amount will result in more migration. Use a pump down cycle so all the refrigerant is removed from the low side of the system. Sign up on Refrigeration Mentor and get full a Free Compressor troubleshooting guide! Liquid Floodback
