This article presents the static and dynamic modelling of two bed adsorption chiller
employing “CHA and AFI type zeolites” as adsorbents and water as adsorbate. The …

With the advantages of no moving parts at low temperature, flexibility and simple structure,
the precooled Joule-Thomson (JT) cryocooler working at liquid hydrogen temperature has …

The last stage of a He-4 Joule-Thomson cryocooler, which is composed of a recuperator, a
JT valve, and a cold heat exchanger, is investigated. It is found that, for given precooling …

In recent decades we witness a surge in electricity consumption rates, thereby, a growing
demand for electricity production and transmission. These trends yield escalating emissions …

Many optical devices can benefit from cryogenic cooling; however, the resolution of these
devices suffers from microvibration from mechanical cryocoolers. Unlike mechanical …

Sorption processes are incorporated in a wide range of applications. A heat and mass
transfer model which calculates the temperature distribution and pressure in a sorption cell …

The cell of the sorption compressor developed in this paper has a thin-plate shape to
accelerate the pressure swing by reducing the heating and cooling periods. Its width, height …

Heat powered cycles are of great interest as they enable reduced electric power
consumption. Therefore, they can lower the load on electric power plants and distribution …

A sorption JT cooler for a cooling temperature of 5 K can be useful to cool the sensitive
detectors and calorimeters, due to its vibration-free characteristic. It is a JT cooler driven by …
