| Abstract [eng] |
Surrounding space around condenser of household refrigerator has sufficient influence on heat transfer efficiency. The experimental and numerical investigations are presented in the article in order determine the influence. Experimental investigation is carried out with condenser at real conditions when it operates in refrigerating system. The average heat transfer coefficient is determined when condenser space is not limited. The results of numerical simulation give a possibility to do analysis of heat transfer efficiency. The results demonstrate that condenser space impacts the heat transfer by up to 14%. Moreover, the results allowed doing a novel solution for more effective heat transfer, i.e. the creation of small artificial air flow upwards by the natural direction. Thus the combined convection case is getting, which is in good accordance with the conventional construction of the condenser. |
