Abstract [eng] |
Considering the environmental challenges the refrigerant charge minimization is one of the most important targets for refrigerating and air conditioning applications. This paper presents a charge minimization study of transport refrigerator with eutectic plates. It was found that in traditional system significant charge increase in evaporator during the initial stage of pull-down was caused by interaction of thermostatic expansion valve and outlet pressure downstream regulator. For the baseline system (A) the charge increase was ~1 kg, i.e. 25% of total charge. This charge increase may be minimized through implementation of different control systems. Other important factors are the volumes of receiver, heat exchangers and liquid line. Two low-charge refrigerators with different control systems were developed and tested. The charge decrease was 40-50% comparing to baseline systems. |
