    • This invention relates to a booster explosive support device 10 for use in boreholes 87. The device 10 includes a securing arrangement 12 which is configured to secure an explosive booster 100 to the device 10, and a spacing element 39 which protrudes from the securing arrangement 12. The spacing element 39 has a free end which in use abuts against a closed end or bottom of a borehole, thereby supporting the securing arrangement 12 and hence an explosive booster 100 at a desired spacing from the bottom of the borehole 87. The spacing element 39 may be elongate. The invention also relates to a method of securing an explosive booster 100 at a pre-determined position in a borehole 87. The method includes spacing the explosive booster 100 away from a closed end of the borehole 87 by supporting the explosive booster 100 from an operatively lower position thereof.

    • Vapour absorption refrigeration is carried out by condensing, in a condensing stage (98), a refrigerant in vapour form to obtain condensed refrigerant, being passed into an expansion/evaporation stage (16) in which it is subjected to heat transfer with a higher temperature medium (29) such that at least some of the refrigerant evaporates. Vapourised refrigerant passes from the evaporation stage into an absorption stage (30) in which some of it is absorbed, at a first pressure, into an absorbent, thereby to obtain partially refrigerant - enriched absorbent. This absorbent is contacted, in a compression absorption stage (58) at a second pressure greater than the first pressure, with vapourised refrigerant, rendering refrigerant - enriched absorbent which is passed from the compression absorption stage into a refrigerant regeneration stage (62), in which refrigerant in vapour form is recovered, rendering refrigerant - depleted absorbent. The recovered refrigerant is recycled to the condensing stage and the refrigerant - depleted absorbent to the absorption stage where it constitutes the absorbent.
    • 蒸气吸收制冷通过在冷凝级(98)中冷凝成蒸气形式的制冷剂,以获得冷凝的制冷剂,进入膨胀/蒸发阶段(16),在膨胀/蒸发阶段(16)中,其经受较高温度的传热 介质(29),使得至少一些制冷剂蒸发。 蒸发的制冷剂从蒸发阶段进入吸收阶段(30),其中其中一些在第一压力下被吸收到吸收剂中,从而获得部分富含制冷剂的吸收剂。 该吸收剂在压缩吸收阶段(58)中以大于第一压力的第二压力与气化的制冷剂接触,使得从压缩吸收级通入制冷剂再生级(62)的富含制冷剂的吸收剂在 蒸气形式的制冷剂被回收,使得制冷剂耗尽了吸收剂。 回收的制冷剂被循环到冷凝阶段,并将制冷剂耗尽的吸收剂再循环到其构成吸收剂的吸收阶段。
