description | Evaluation of energy efficiency of a combined cooling system that uses night radiative cooling together
with refrigerating machine with accumulation of cold without a phase transition and the supply of liquid
coolant (propylene glycol) to the air cooler is performed based on the results of computer simulation.
In the cooling system located in Kostanay (Kazakhstan), there are radiators (12 m2) that cool the
coolant at night, as well as a conventional vapor compression refrigerating machine with a reciprocating
compressor. The cooling system is used to maintain air temperature at the level of 0±1°C in a small
refrigeration chamber (36 m3) with a low value of heat emission from stored products and the absence
of other operational heat influx. It is found that 78,8 days a year the cooling system can maintain the
required temperature due to the operation of radiators without turning on the refrigerating machine.
This saves 242 kWh of electricity. Thus, the combined refrigeration system provides 7,6% reduced
energy consumption, and also reduces physical deterioration of the refrigerating machine compressor
for the annual cycle, which should reduce the financial costs for operating the refrigeration warehouse |
