The equipment used for removing the heat continuously for maintaining a low temperature in a space is called 'refrigerator'. In the last session, we had discussed Vapor Compression Refrigeration Cycle and in today's session, we can discuss in detail the concept of Refrigeration along with its Definition, Unit, Classification of Refrigerants and Applications.

Advantage And Disadvantage Of Air Conditioner

The virtues of air refrigeration, including cheapness, availability and safety of the refrigerant used made it quite appealing to the early inventors of refrigeration machines. Air refrigeration dates back to the middle of nineteenth century, but it was not until that a reliable unit was developed. It was used mostly for cold-storage of meat on ships. However, the equipment was bulky and inefficient. The bulkiness was due to the reciprocating compressor and expanders and low speed of rotation. Recent developments in the rotary compressors and gas turbines have renewed interest in air refrigeration systems.

Ans Air Refrigeration Ans Refrigeration. It is not much in use because of moisture added to air in the cabin. The pressure of cooled air in such systems is much higher than in the open system. Because of high pressure, volume is less and hence density of air is high. It is therefore also called a dense system.

It condensed and evaporates at temperatures and pressures close to the atmospheric conditions. The refrigerants usually used for this purpose are ammonia, carbon dioxide and sulphur dioxide. Advantage and disadvantages of vapour compression and air refrigeration system: Advantage: 1. It has smaller size for given capacity of refrigeration. It has less running cost. It can be employed over a large range of temperatures 4. The coefficient of performance is quite high.

Но, приближаясь к рубильнику, Стратмор понял, что ему необходимо преодолеть еще одно препятствие - тело Чатрукьяна на ребрах охлаждения генератора. Вырубить электропитание и снова его включить значило лишь вызвать повторное замыкание. Труп надо передвинуть. Стратмор медленно приближался к застывшему в гротескной лозе телу, не сводя с него глаз. Он схватил убитого за запястье; кожа была похожа на обгоревший пенопласт, тело полностью обезвожено.

 Нет, - сказала она раздраженно.

 - Стратмор пожал плечами.  - Имея партнера в Америке, Танкадо мог разделить два ключа географически. Возможно, это хорошо продуманный ход. Сьюзан попыталась осознать то, что ей сообщил коммандер. Она сомневалась, что Танкадо мог передать ключ какому-то человеку, который не приходился ему близким другом, и вспомнила, что в Штатах у него практически не было друзей.

Приготовиться. Приступайте. - Мы не успеем! - крикнула Соши.  - На это уйдет полчаса. К тому времени все уже рухнет.

Она улыбнулась и поудобнее устроилась в постели.
