리니어 압축기를 적용한 냉장고 사이클의 냉동 부하변동에 따른 운전특성에 관한 연구

An experimental investigation on effects of variation of ambient temperature and compressor stroke in a refrigerator was conducted with a linear compressor. The refrigerant of 115g was charged from the results of comparing the power consumption and on-time ratio with different refrigerant charge amount. The cooling capacity of a linear compressor was increased with the ambient temperature increase due to ability of self-modulation of the compressor. The power consumption and cooling time were compared with variation of the cooling capacity of a linear compressor from 60% to 100%. As a result, the power consumption of a linear compressor was reduced by 22.4% with the compressor capacity increase. However, on-time ratio was increased by 11.3%.
