An effective means of raising public awareness of energy conservation
In recent years, the use of frequency converters in make-up water pumps has proven to be an effective way to reduce energy consumption. By starting the pump at a lower frequency and voltage, the system minimizes the stress on the motor and reduces power surges. This approach leads to more stable pressure control compared to traditional on-off regulation methods. Additionally, the two-part energy pricing model aligns well with China’s current energy policies. In summer, when indoor temperatures rise, and in winter, when heating demands decrease, this system helps achieve significant energy savings.
Implementing cold and heat metering in buildings is a crucial step toward raising public awareness about energy conservation. Metering systems can encourage users to adopt more energy-efficient behaviors by making them directly responsible for their consumption. It is essential that these metering charges are introduced alongside building energy efficiency improvements to ensure a balanced and sustainable approach.
From a development perspective, the implementation of cold and heat metering should not only rely on policy enforcement but also focus on human-centered design. It must be user-friendly and socially inclusive, especially to protect the interests of vulnerable groups. While China has made considerable progress in research and practical applications of metered heating and cooling, challenges remain. The complexity of building temperature management involves not only technical issues but also a lack of public awareness regarding energy conservation.
To address these issues, increasing public education, strengthening policy support, and expanding engineering practices related to cold and heat metering are all vital strategies for promoting energy-conscious behavior. These efforts will help create a more sustainable and efficient built environment.
Additionally, in certain industrial applications, such as ammonia absorption refrigeration cycles, the condensation process can lead to poor temperature matching between the working fluid and the constant-temperature cold source. To solve this issue, a regenerative flash and condensation absorption system is often added to the cycle, improving overall efficiency and performance. This innovation ensures better thermal compatibility and enhances the effectiveness of the entire system.
