| Abstract |
The outer wall system of an existing refrigerated warehouse is generally used to insulate the inner and outer sections of a concrete wall. However, there is a great deal of energy loss caused by the thermal bridge of concrete slabs. To overcome this problem, the PC insulation envelope system(dry method) is used in this paper. The PC insulation envelope system has a minimum of 100mm of thermal insulating material. It is necessary to develop proper insulation methods in order to use those methods in the PC envelope system of refrigerated warehouse effectively. Both model and mock-up tests were conducted to verify the pumping insulation methods using inner and outer wall materials as a foam panel of concrete construction. The tests indicate that the two insulation methods(Injection pumping and Spray pumping) suitable for the envelope system of refrigerated warehouse proposed by this research is effective for short-term work as well as a unity of insulation |
