Often called the “heart” of the system, the compressor plays a crucial role in the operation and performance of an air conditioning or refrigeration system. That’s because without a compressor, there is no cooling for people or product. However, many end users are looking for more from their systems than just reliable cooling; they also want sustainable equipment that features better energy efficiency and low-GWP solutions. Manufacturers have happily obliged, designing a number of new compressors that not only save energy, but also use low-GWP refrigerants.
