There are varying types of symptoms that can occur when a refrigeration system has an overcharge of refrigerant.

Understanding the purpose of the distributor and how to properly size and install these components can be helpful to any refrigeration technician.

Four core components work together to control when refrigerant is absorbing heat, and when it is releasing heat.

Ask several refrigeration technicians about the best location to place a sight glass, and you will probably get several different answers.

Refrigeration and a/c compressors are vapor compressors, meaning they are designed to compress refrigerant vapor, not liquid refrigerant.

This article will hopefully save the lives of a few TXVs and the pocketbooks of some customers.

Understanding how accessories are properly used will allow technicians to better maintain and repair refrigeration systems.

In one of its sections on TXVs, the book points out that “this component is widely used for nearly all types of air conditioning and refrigeration systems. The advantage of the TXV is its ability to automatically adjust to match the load, as it is designed to sense changes in the refrigeration load and respond to them.”
