As HVACR technicians, you need some ideas in your back pocket for basic troubleshooting in a refrigeration system. How about a simple chart that helps you diagnose a system with 3 data points for starters? Using this chart is simple and can greatly speed up the troubleshooting of a system while in the field.
A common problem facing refrigeration and air conditioning service technicians and contractors is superheat hunting by thermostatic expansion valves (TEVs). Here is a better understanding of a commonly overlooked cause of superheat hunting and how the problem might be corrected.
Refrigerant choices for refrigeration systems are undergoing significant change, including choices for retrofits and new systems. This article is Part 1 of a 3 part series addressing such retrofits and deals with the basics of refrigerant blends and temperature glide.
The thermostatic expansion valve (TEV) provides an excellent solution to regulating refrigerant flow into a direct expansion type evaporator. The TEV controls the flow of liquid refrigerant entering the direct expansion (DX) evaporator by maintaining a constant superheat of the refrigerant vapor at the outlet of the evaporator. To understand the principles of TEV operation, a review of its major components is necessary.
