Technicians need to to be aware that ice machine servicing expertise might be just one small part of the technology they could encounter on a single piece of refrigerated equipment. 

Some of the newest electronic technologies were on display at the 2014 National Restaurant Association Restaurant, Hotel-Motel Show.

Often, compressors in the refrigeration and air conditioning fields have forced oiling systems. Here is a look at some of those oil pumps.

An excessive pressure drop across the suction line will reduce the operating capacity of a refrigeration system.

The IIAR Conference examines some of the latest research in terms of working with equipment running on natural refrigerants.

The most recent International Institute of Ammonia Refrigeration Conference took a look of some of the latest research in terms of working with equipment running on natural refrigerants. The significance was not lost on attendees as such refrigerants continue to gain a foothold in commercial and industrial applications.

An overview of the oil check valve, which will only let oil pass from the compressor’s motor barrel to its crankcase.

The compressor’s discharge line temperature is important because it is an indication of the amount of heat absorbed in the evaporator and suction line and any heat of compression generated by the compression process.

Recovery of refrigerant may be a common practice in HVACR servicing, but it is still a skill that requires care and caution. Awareness of step by step procedures can help all technicians better understand what’s involved in the process.

Migration of refrigerant to the compressor’s crankcase during an off cycle is a serious problem, as significant compressor damage can occur if the problem is not remedied.
