Applications of Thermodynamics: Heat Pumps and Refrigerators
WebChapter 5: The Second Law of Thermodynamics. In this chapter we consider a more abstract approach to heat engine, refrigerator and heat pump cycles, in an attempt to determine if they are feasible, and to obtain the limiting maximum performance available for these cycles. The concept of mechanical and thermal reversibility is central to the ... WebEngines and Refrigerators 11. T H T C Q H Q C W ... HEAT ENGINE The objective: turn heat from hot reservoir into work ... Example 1 Consider a hypothetical refrigerator that takes 1000 J of heat from a cold reservoir at 100K and ejects 1200 J of heat to a hot reservoir at 300K. 1. How much work does the refrigerator do? WebREFRIGERATOR . A refrigerator is a Carnot’s engine working in the reverse order. It is shown in the figure 8.49. Working Principle: The working substance (gas) absorbs a quantity of heat Q L from the cold body (sink) at a lower temperature T L.A certain amount of work W is done on the working substance by the compressor and a quantity of heat Q H is rejected to the … buy a380 airbus
