Refrigerator Heat Engine Diagram

A heat engine is a device that converts heat to work.

Refrigerator heat engine diagram. A refrigerator is a reverse. Of heat engine refrigerator and heat pump is discussed below heat engine fig a shows a schematic diagram of the heat engine. It takes heat from a reservoir then does some work like moving a piston lifting weight etc and finally discharging some of the heat energy into the sink. Schematically it can be represented as.

The heat supplied to sink is equal to q1. Heat is always transferred from a hotter object to a colder object. In a heat engine heat is transferred from a higher temperature level called source to a lower temperature level called sink. Work is obtained during this process.

Carnot engine diagram modern where an amount of heat q h flows from a high temperature t h furnace through the fluid of the working body working substance and the remaining heat q c flows into the cold sink t c thus forcing the working substance to do mechanical work w on the surroundings via cycles of contractions and expansions.

All three devices work on the basis of heat flow. The gas in a refrigerator can extract heat qc from the cold reservoir only if the gas temperature is lower than. In general the efficiency of a given heat transfer process whether it be a refrigerator a heat pump or an engine is defined informally by the ratio of what is taken out to what is put in. Heat engine took q2 amount of heat from the hot body and did work equivalent to w e.

Let us derive an expression for the efficiency of a.
