Document Summary
11 refrigeration cycles: refrigerator: a cyclic device that transfers heat from a low-temperature region to a high temperature region. Works to maintain a cool space at a low temperature by removing heat from it: heat pump: cyclic device that transfers heat from a low temperature medium to a high temperature one. Works to maintain a heated space at a high temperature by absorbing heat from a low-temperature source and supplying that heat to a warmer medium: coefficient of performance: measures the performance of heat pumps and refrigerators. 11. 2: the reversed carnot cycle: all four of the processes that happen in the carnot cycle are reversed. Reversing the cycle also reversed the direction of any heat and work interactions: the cop of reversed refrigerators and heat pumps can be expressed in terms of temperature: Cophp, carnot : the reversed refrigerator carnot cycle is the most efficient cycle operating between two specified temperature levels.
