Saving Effect

The energy-saving effect of the injection molding machine energy-saving reformation project was measured in a factory. Based on the analysis of the project energy-saving principle, analyzed the energy-saving rate of the reformed injection molding machine in case of producing different products. The test results show that the active power saving rate is 50% under the load condition, the active power saving rate is more than 75% under the no-load condition and energy-saving effect is more obvious under the no-load condition. Finally, analyzed the power quality impact caused by the energy-saving equipment on the distribution network, put forward some suggestions for improvement.

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.

Reducing heating temperature is a universally recognized energy saving measure. However, the same city has buildings completed in different years and with different functional USES at the same time. It is an important issue worth discussing whether it is reasonable for the government to advocate reducing heating temperature by the same range. Based on DOE medium-sized office building as the object, using the Beijing meteorological database system, the thermal characteristics of four envelopment structures representing different completion years, the annual heating energy saving and relative energy saving ratio when the set indoor heating temperature is reduced by the same range are studied. The results show that the worse the thermal performance of the envelope is, the greater the annual heating energy is when the heating setting temperature drops by the same extent. It indicates that the older the building is, the better heating energy saving effect and more heating cost can be achieved by advocating lowering the heating setting temperature of the same range. For the annual relative energy saving ratio, the older buildings with worse envelope structure are slightly higher, while the new buildings with better envelope structure are slightly lower, but they are similar on the whole. It is proved that the policy of reducing heating temperature by the same range in the same city is reasonable for achieving similar energy saving ratio.
