| Abstract: |
According to the characteristics of variable operating conditions and high exhaust temperature of the refrigeration system of the refrigerator truck, the change of the superheat at the outlet of the evaporator is adjusted by a new electronic expansion valve, and a performance test-bed using the R404A refrigerant is built to study the influence of the superheat at the outlet of the evaporator on the performance of the refrigeration system of the refrigerator truck. The results show that in the process of increasing the superheat at the outlet of the evaporator, the outlet temperature of the evaporator increases and the evaporation temperature decrease, the cooling capacity of the system is reduced by 8.4%, and the COP of the system increases first and then decreases; At this time, the optimal superheat at the evaporator outlet is 6 °C, and the system COP reaches the optimal value of 2.856.
