Even though the circulated refrigerant is the working fluid required for cooling, lubricant or oil is needed for lubrication of the compressor’s moving mechanical parts.
Equipment still fails like it did before 2020, but depending on your customer base, scheduling jobs can be a little more frustrating since the start of the pandemic.
The HFC phasedown and impending transition to lower-GWP refrigerants were top-of-mind at the recent AHR Expo. With the AIM Act, there is no stopping the transition to A2L refrigerants.
Refrigerants used in vapor-compression air conditioners and heat pumps have been the subject of environmental regulations, requiring the need to develop alternative solutions with lower GWP.
As more refrigeration systems incorporate electronic controls into their design, it is important for technicians to be able to troubleshoot these electronic devices, such as the pressure transducer.
