Minichannel heat exchangers in refrigerating equipment
Annotation
Data on the evolutionary development of heatexchange devices which allowed to increase significantly their specific efficiency are presented in article. It is shown that in heatexchange devices in the last decades the microchannel technologies allowing to create compact devices are widely applied. The diameter of the channel is less, the big heatexchange surface can be concentrated in unit of volume. In relation to refrigerating equipment minichannel condensers with air cooling are created. They complete refrigerating units and conditioners of rather small productivity. Thus technical characteristics of units improve, the volume of gas station of coolant in system is reduced. Creation of minichannel evaporators requires the solution of a number of technical problems.
