: Now a day’s refrigeration became an essential part of the food chain. It is being used in all stages, from food processing, to distribution, retail and final consumption in home. This report presents a preliminary investigation on the development of electronic expansion valve technology for Transport Refrigeration Systems. Road transport refrigeration equipment is required to operate reliably in much harsher environments than stationary refrigeration equipment. At all the ambient conditions and different cargo box temperatures it is very difficult to maintain required capacity and constant set point temperature which are the basic requirements for the food industries to maintain product quality till the delivery. The expansion valve currently used for the most of the TRS is Thermostatic Expansion Valve. Though it is less expensive compared to EEV, it has its own limitations to meet various requirements of TRS. To have solution for this problem incorporate a very well-organized expansion valve which can regulate the appropriate mass according to the capacity need along with temperature and super heat control. Though the cost of EEV is high, versatile characteristics of EEV which can able to satisfy or improve the performance of refrigeration cycle. This paper provides the benefits that can be added through the EEV for transport refrigeration cycle to overcome limitations of TXV.
