Аннотация: | The self-insulation wall is widely used in the field of architecture because it involves a simple construction process, saves resources, and reduces environmental pollution. In this study, self-insulating block experimental groups of different filling rates and filling place positions were made to obtain the most suitable filling scheme for self-insulating hollow blocks in cold climates and intermittent running of air-conditioning. The working conditions of different types of self-insulating block groups were simulated and recorded using hot and cold box-heat flow meter methods in a cold climate and intermittent operation of air-conditioning. The results show that some previous research conclusions are still applicable in a cold climate and intermittent running of air-conditioning. The experimental group filled with insulation materials in the middle of the hole showed a better thermal performance at a filling rate of 25%; the experimental group filled with insulation materials in both sides of the hole exhibited better thermal properties at a filling rate of 50%. When compared with 5 other types of cases, the average heat flow of Case 2 was the smallest and was between 18.36 W/m2 and 21.89 W/m2, therefore, the intermittent running mode of Case 2 was found to be the best. © 2022 The Authors. |
