摘要	The Vapor Compression Cycle is the fundamental thermodynamic cycle for refrigeration systems and heat pumps. It describes how mechanical work is used to transfer heat from a cold space (evaporator) to a warm space (condenser), operating against the natural temperature gradient. The cycle consists of four processes: isentropic compression, isobaric condensation, isenthalpic throttling, and isobaric evaporation.	The Brayton Cycle (also called Joule Cycle) describes the thermodynamic process in gas turbines and jet engines. It consists of four processes: isentropic compression in a compressor, isobaric combustion (heat addition), isentropic expansion in a turbine, and isobaric heat rejection. The Brayton Cycle is the foundation for analyzing aircraft propulsion, ground-based power generation, and simple-cycle gas turbine plants.	Psychrometric analysis is the study of humid air (air-water vapor mixtures) and its properties. It is essential for designing and analyzing air conditioning, ventilation, and dehumidification systems. Psychrometric analysis relates dry-bulb temperature, wet-bulb temperature, dew point, relative humidity, and specific humidity through carefully constructed charts and correlations.
