Fundamentals of Refrigeration section – Pressure-enthalpy diagram – Refrigeration cycle (1). I. Overview: The refrigeration method we commonly use is phase-change refrigeration in artificial refrigeration, which involves heat absorption during evaporation (in the evaporator) and heat release during condensation (in the condenser). The refrigeration cycle is accomplished through the phase transition of the refrigerant between gas and liquid states. Question: What are the four main components of a refrigeration system? (In order of the refrigerant’s flow) Answer: Compressor – Condenser – Throttling element – Evaporator ============================== Premium promotion: Daily questions on mechanical equipment in the field of refrigeration – Their value and functions https://bbs.hcbbs.com/thread-2848974-1-1.html Mechanical equipment – Internal training materials for screw refrigeration compressors manufacturers https://bbs.hcbbs.com/thread-2850090-1-1.html
