The effects of cold storage agent′s sort and weight on cold storage capacity in hold-over plate, and effects of cold storage agent′s sort,environmental temperature,solar radiation,leakage from doors etc on charging time are analysed The ways of increasing cold storage capacity in hold-over plate and reducing charging time are put forward This paper will provide theoretical base for design of hold-over plate,transportation and management of hold-over plate refrigerated trucks
With the 120 km/h mechanical cool plate refrigerator car as an example, through the structure optimization, sensitivity analysis and parameter optimization of the car-body steel structure, the analysis and calculation methods of lightening of the car-body load-carrying structure are provided.
The calculation method for the heat load of cool plate refrigerator car in operation is des-cribed, and the heat load in transport of the frozen and cooled goods is calculated with the actual example. The theoretical basis is provided to reduce the heat load in operation of cool plate refrigerator car and ensure the quality of refrigeration transport for goods.
For moderate to large wave numbers, density variations have little effect except that there exists a range of cool plate temperatures for which these disturbances are extremely stable.
The development general of the new mechanical colling board refrigerator car,the main performance,structural characteristics and the first operation are introduced
The development process of the new type eutectic liquid needed on the 120 km/h mechanical cooling board type refrigerator car is described.The main physical and chemical parameters of the GJY-02 eutectic liquid are measured.And the qualitative and quantitative inhibition tests are completed.
