The Green Logistics Idea using Vacuum Insulation Panels (VIPs)

Abstract

This research aims to reduce fuel consumption in transportation systems using vacuum insulation panels (VIPs) for cold storage trucks. The material was vacuum Insulation Panels (VIPs) is a custom-made insulator using glass fibers pressed at 10 tons per square meter and the thermal conductivity conditions of the selected materials ranged between 0.0028 and 0.007 W/mK and has a size of 12 mm comparative experiment method of cold storage trucks equipped with VIPs and without VIPs of 4 model frozen cars. Which has Model 1 (4 Wheels Truck), Model 2 (4 Wheels large Truck), Model 3 (6 Wheels Truck), and Model 4 (10 Wheels Truck). The sensor installation in the cold room is distributed in every wall to achieve differentiation and distribution of cold temperatures. The results are calculated as the energy saving result, it was found Model 1 (4 Wheels Truck) have best fuel savings. This research can apply other types of cold storage trucks or research in the same way as the air wall by inserting VIPs insulation inside the external insulation to reduce heat transfer.

Low GWP Refrigerant R1234yf, R1234ze(z), R13I1 as an Alternative to New Zeotropic Refrigerant

“…It can be seen that it is a refrigerant with properties similar to R134a. R1234yf and R1234ze(z) therefore can be mixed with HFCs [11]. All refrigerant in this study uses the national institute of standards and technology (NIST) reference fluid thermodynamic and transport properties database (REFPROP) software and NIST vapor compression cycle model accounting for refrigerant thermodynamic and transport properties (CYCLE_D-HX) software as CAN/ANSI/AHRI540 standards of the Air-Conditioning, Heating, and Refrigeration Institute (AHRI), as shown in Table 1 [12].…”

Aerodynamic Performance Enhancement of a Heavy Trucks using Experimental and Computational Investigation

“…The calculation method of the specific exhaust emissions for a compression ignition (C.I) engine fuelled by palm biodiesel blend was proposed by Sarwani et al, [3] and the percentage of volumetric emission into specific emission (g/km) was investigated. The effect of vacuum insulation panels (VIPs) was studied to reduce consumption of fuel in transportation systems for cold storage trucks [4].…”
