One of the worst enemies of a compressor is liquid refrigerant, so technicians should make sure the refrigeration system has proper superheat in order to protect the compressor from damage that can occur from flooding or slugging.

Proper evacuation of a refrigeration system is an important part of repairing or installing a unit, and the gas ballast in the vacuum pump helps improve the process.

Technicians need to make sure that the TXV is not underfeeding refrigerant to the refrigeration or air conditioning system due to a restriction, which can be caused by a number of factors.

Making sure the TXV is metering the right amount of refrigerant into the evaporator and is not overfeeding the coil is one way technicians can help their customers’ refrigeration and air conditioning systems operate safely and more efficiently.

Liquid line restrictions cause the evaporator, compressor, and condenser to be starved of refrigerant, causing performance problems in refrigeration systems.

As the old saying goes, an ounce of prevention is worth a pound of cure. This is especially true when a replacing a thermostatic expansion valve (TXV).

This article will explore the remote bulb and its proper placement on a system’s suction line.

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.
