Refrigerant Cycles Without Compressors
Many HVAC/R technicians (including me) describe the compressor as the heart of the refrigeration cycle. It prepares the refrigerant for the condensing process, which is crucial for heat rejection. However, some refrigeration methods don’t require a compressor. In this article, we’ll look at those methods and their applications. Gas movement without compressors As you […]Read more
In residential and light commercial HVAC, we work primarily with PSC (permanent split capacitor) motors. However, it is good to be aware of some other types. PSC (Permanent Split Capacitor) A common medium torque single phase motor with a run capacitor always in the circuit. This type makes up the majority of HVAC motors (condenser […]Read more
