Modelling of the operation of a refrigeration unit using radiative cooling to maintain the storage temperature in the cold room
The results of the research, which show the effect of radiative cooling on the temperature of food storage chamber during the cold season in the cities of Almaty and Kostanay (Kazakhstan) were obtained through computer simulation of the operation cycle. In the installation modelled, pumping circulat...

description |
The results of the research, which show the effect of radiative cooling on the temperature of food storage chamber during the cold season in the cities of Almaty and Kostanay (Kazakhstan) were obtained through computer simulation of the operation cycle. In the installation modelled, pumping circulation of a heat carrier cooled at night in radiators is used. The radiators of the installation cover the entire roof of the cold room (12 m2). Computer simulation shows that the required temperature in the cooled chamber (0 ... + 3 ° C) is maintained in Almaty for 8.5%, and in Kostanay for 28.2% of the total length of the year. The average coefficient of performance of the unit was 3.43 in Almaty and 4.63 in Kostanay. Although the installation with radiation cooling is operational, in the proposed scenario its practical application is not advisable. |
