Abstract

Introduction of new effective «know-how» of urea causes the necessity of decrease of expenses for reception of low-temperature liquid carbon dioxide. For definition of values of extremely low expenses is constructed the model of ideal cycle of carbon dioxide refrigerating machine (CDRM) working in a mode of liquation CO2. It is offered for decrease of specific expenses of energy on manufacture of the specified product, and also for increase of exergic efficiency of idealized CDRM to use in them overcooling condense at ambient temperature CO2 with the help of external refrigerating machines. As such machines the compressor refrigerating machine working on R134а, or absorptive lithium bromide refrigerating machine is applied. Comparison of characteristics such CDRM with machines realizing cycles of low and average pressure, shows that they don't possess advantages in comparison with carbon dioxide machine of high pressure in which overcooling of liquid CO2 before it throttling is applied.
