Verification of computer simulation of a flow of a coolant in a buffer tank of cooling system

Timofeyevsky A.L., Borozdkin S.V. , Saifullin T.I.

The compressor water-cooling cars (chillers) widely are used in various industries. One of the main reasons for reduction of a resource, and sometimes and a compressor discharge its work as short cycles out of operation is. In systems of cold supply with chillers it is recommended to protect compressors from frequent inclusions by use of buffer capacities, however there are certain contradictions in recommendations about the internal device of buffer tanks demanding carrying out numerical modeling of a current of hladonositela in them. The purpose of modeling is comparison of time of transfer by buffer capacities of different designs of fluctuations of temperature of a hladonositel. Authors executed comparison of the data obtained at a pilot study and numerical modeling of hydrodynamics of a current of a hladonositel in the buffer capacity of system of cold supply and the conclusion is drawn on their good compliance that gives the chance in further to use the used numerical model for calculation of capacities of different designs and the sizes. Comparison of the data obtained at a experimental study and numerical modeling of hydrodynamics of a flow of a coolant in buffer tank of system of cool-ing system.
