“…Due to advantages of high reliability, simple matching between expander and brake blower, easy regulation and so on, a brake blower is often used to regulate the turboexpander in small reverse Brayton refrigerator [5,11]. Hou et al [11] proposed a brake pressure feedback control to reverse Brayton air refrigerator, with which the maximum turboexpander efficiency could be obtained under different operating conditions. The refrigerator cooling capacity could be regulated through the brake blower.…”

“…(2) The refrigeration temperature range is wide and the operating performance is excellent under low temperature. The refrigeration temperature can be adjusted in a wide range above 0 ℃, which can meet the requirement of working in the field of low temperature under -30℃ for a long time, and this is the unique advantage of air refrigeration system.…”

“…But the alternatives are not only expensive but also partly toxic. Although the destruction of the Ozone layer resulting from the use of CFCs is effectively avoided, the influence of the unknown risk on people's daily life cannot be ignored [1,2]. Air cycle refrigeration technology is a kind of environment-friendly and resource-saving mode of refrigeration, for using air as the refrigerant, the cost is low and dispose of air generating no pollution.…”

“…Two kinds of journal bearings, copper wire support and viscoelastic support, were compared for small cryogenic turboexpander of 12 mm diameter around 220000 rpm [6]. Recently, bump foil journal bearings was applied in the above turboexpander that could operate smoothly in a wide speed range [25]. Numerical results indicated that the journal bearing was stable in high speed range [26].…”
