absorption refrigeration

absorption refrigeration

[əb′sȯrp·shən rə‚frij·ə′rā·shən]
(mechanical engineering)
Refrigeration in which cooling is effected by the expansion of liquid ammonia into gas and absorption of the gas by water; the ammonia is reused after the water evaporates.

Absorption refrigeration systems have been studied by using analysis of the 1st and 2nd Law of Thermodynamics, considering conditions of permanent regime (Somers et al., 2011; Ochoa et al., 2014) and also, a transient regime (Zinet, Rulliere, & Haberschill, 2012; Evola, Le Pierres, Boudehenn, & Papillon, 2013; Ochoa, Dutra, Henriquez, & Santos, 2016), the purpose of which is to verify the influence of technical parameters such as; temperature, pressure and flow on the COP of the system.
Simulations of a 60 kW solar chiller are performed in order to analyze thermodynamically and predict the performances of a combined ejector single-effect absorption refrigeration cycle coupled with linear Fresnel collector modules.

Gas refrigerators are also known by other names, such as bottle gas fridge, LP fridge, propane fridge and absorption refrigeration. The last name is the most proper of them all, because they use the absorption principle to move heat from inside the refrigerator to outside the refrigerator.
