Reflective Coatings

In this article, we mixed hollow glass beads with nano-TiO2 and iron oxide red in a certain proportion to prepare a low-brightness, high-reflective, safe, and durable cooling coating throughout the experiments. The coating is suitable for energy-saving in tropical areas. To discuss the energy saving effects of the coating on an exterior envelope in tropical areas, a comparative analysis for two scenario models of a two-story residential building in Kuala Lumpur, Malaysia was conducted. The results indicated that the heat reflective insulation coating could reduce the exterior envelope surface temperature effectively, and the maximum temperature change was about 6–8 °C. Through calculations, it was found that the annual energy saving rate was 12.9%, which showed that the energy saving effect of the heat insulation coating was obvious in Kuala Lumpur. The brightness of the coating was less than 50%, and its comfort and safety met the requirements.

Abstract This paper analyzes the energy saving effect and optimal operation of the integrated park type energy system. The park type integrated energy system includes photovoltaic power generation system, ground source heat pump system, solar air conditioning system, regenerative electric boiler system and solar hot water system and so on. The energy saving benefit calculation model of each subsystem is established, and according to the operation history data of each subsystem, the calculation results of each subsystem are analyzed. It shows that: The energy saving income of photovoltaic power generation system is 734,200 yuan/year. The main revenue comes from the second and third quarters, during which it should pay attention to the maintenance of photovoltaic modules to ensure the maximum energy saving benefit. The energy saving income of ground source heat pump system in summer is 155,900 yuan/year, and the energy saving effect is not significant. It can cooperate with traditional units for cooling in summer. The heating in winter in the park is provided by ground source heat pump system, regenerative electric boiler system and solar energy air conditioning system. Its energy saving benefit is 3.995 million yuan/year which is the main source of energy saving income in the park, with remarkable energy saving effect.
