Refrigeration - Wikipedia

The term refrigeration means cooling a space, substance or system to lower and/or maintain its temperature below the ambient one (while the removed heat is rejected at a higher temperature). In other words, refrigeration is artificial (human-made) cooling. Energy in the form of heat is removed from a low-temperature reservoir and transferred to a high-temperature reservoir.

Rankine Cycle - an overview | ScienceDirect Topics

Bruce G. Miller, in Clean Coal Engineering Technology, 2011 7.1.1 Rankine Cycle. The Rankine cycle is the basis of all large steam power plants, as briefly discussed in Chapter 6 (refer to Figure 6.16).In coal-fired power plants, high-temperature, high-pressure steam is produced by converting the chemical energy stored in the coal into thermal energy and transferring the energy to the working

Turboexpander - Wikipedia

A refrigeration system utilizes a compressor, a turboexpander and an electric motor. Depending on the operating conditions, the turboexpander reduces the load on the electric motor by 615% compared to a conventional vapor-compression refrigeration system that uses a throttling expansion valve rather than a turboexpander. Basically, this can be seen as a form of turbo compounding.

Stirling Cycle - an overview | ScienceDirect Topics

The Stirling cycle (patented 1816) is a thermodynamic model, this time based exclusively on a gas state. Figure 14.3 presents in a PV diagram an ideal cycle consisting of four steps, two isocoric (constant volume) heat exchange and two isothermal expansion/compression changes. Initially, the gas is compressed from P 4 to P 1 isothermally by removing the amount of heat Q C.
