Energy saving is a long-term development strategy for my country’s sustainable developmentBasic national policy; A new type of high-efficiency energy-saving composite insulation board developed by our company can effectively improve the energy utilization efficiency, protect and improve the environment, and promote the comprehensive, coordinated and sustainable development of the economy and society.

At present, the energy consumption of cold storage and refrigerated vehicles is mainly concentrated in the refrigeration system, accounting for about 60-70% of the total energy consumption, and the core factor that determines the amount of energy consumption is the thermal insulation performance of their enclosure. Cold storage and refrigerated trucks mainly use polyurethane as thermal insulation material, the thermal conductivity of polyurethane is 0.023w/(mk); the company has developed a new type of high-efficiency energy-saving composite insulation board, which is made of vacuum insulation board and polyurethane. The thermal conductivity of the vacuum insulation panel can reach 0.0020w/(mk). Taking the 11cm plate as an example, the total heat transfer coefficient of the 11cm thick polyurethane board is 0.209w/(m2.K), and the total heat transfer coefficient of the 11cm thick new high-efficiency energy-saving composite insulation board can reach 0.167w/(m2 .K). According to the calculation of 10,000 cubic meters -18 ℃ freezer, the ambient temperature is 20 ℃, the theoretical calculation of power consumption per day is: 1164.48 degrees per day using 11cm pure polyurethane board, such as using 11cm new high-efficiency energy-saving composite insulation board produced by our company, The power consumption is 1317.43 kWh/day. It can be seen that using the 11cm new high-efficiency energy-saving composite insulation board produced by our company reduces the power consumption by 17.03% compared with the 11cm pure polyurethane board. 

At present, the transportation department of our country divides refrigerated trucks into eight grades, which are grades A to H.

According to thermal insulation performance requirements, it is divided into two categories: Category Ⅰ and Category Ⅱ
