compression refrigeration

compression refrigeration

[kəm′presh·ən ri‚frij·ə′rā·shən]
(mechanical engineering)
The cooling of a gaseous refrigerant by first compressing it to liquid form (with resultant heat buildup), cooling the liquid by heat exchange, then releasing pressure to allow the liquid to vaporize (with resultant absorption of latent heat of vaporization and a refrigerative effect).

Simultaneously, in pursuit of high energy efficiency a two-stage compression refrigeration cycle was adopted and optimal engineering of the refrigeration cycle was carried out through optimization of pipe diameters, etc.
components of the heating system include: gas boilers, heat pumps (reversible), compression refrigeration machines, circulating pumps, energetically activated bored piles, pipelines with insulation, heating / cooling ceilings, ceiling convectors, underfloor heating.
At the beginning of the 20th century, engineers had been building and operating vapor compression refrigeration systems for nearly 50 years but had a very sketchy idea of what was actually happening.
The main objective of this work is to write simulation program for a vapour compression refrigeration system in order simulate its steady state behavior.
It has been employed to achieve very low temperatures and it does not involve any harmful ozone depleting gases as in the case of conventional vapour compression refrigeration systems.
From this study, it found that solar absorption refrigeration and solar electric compression refrigeration had a high energy saving also have a beast performance.
As a result, a director of the New Zealand and Australian Land Company (NZALC) was dispatched to London to investigate a new technology, Bell-Coleman compression refrigeration units.
This is used to support ancillary systems such as feed pumps, an alternator and fans for air circulation, and to drive the compressor of a vapour compression refrigeration cycle that provides additional cooling.
Absorption cycles can be associated with heat-driven cooling cycles, such as the case of a heat-driven power cycle that drives a mechanical compression refrigeration system (Herold et al.
