The Carnot Cycle

A Carnot cycle is a particular type of internally reversible cycle (can be a power, refrigeration, or heat pump cycle). Each of the process steps is assumed to be internally reversible, e.g., • frictionless and no viscosity • quasi-equilibrium • expansions/compressions occur very slowly

REFRIGERATION CYCLE - operations.fnal.gov

REFRIGERATION CYCLE The refrigeration cycle shown here is a typical R-22 system. The compressor and thermal expansion valve are the boundaries for the high and low sides. It's important to understand that a refrigerator is a heat engine that operates in reverse. Energy is transferred from a low level to high level, which is contrary to

Refrigerant Piping Handbook

Good refrigeration piping design requires that the refrigeration lines be pitched in the direction of flow at approximately 1/2 inch per 10 feet or 1 inch per 20 feet. Refrigerant velocities in vertical lines should be at least 1500 ft/min to ensure good oil return;
