**Editor's Note:** To help readers better understand the latest energy-saving technologies and innovations, the City Energy-Saving Monitoring Technology Service Center has selected a range of products to introduce through our "Live Show of Energy-Saving Products." Each week, we will feature different types of energy-efficient devices, accompanied by scientific explanations, upcoming exhibitors, and product details. This initiative aims to raise awareness and promote the adoption of green technologies in daily life.
In recent years, heat pump water heaters have gained popularity due to their ability to recover low-temperature waste heat and offer significant energy savings across all age groups.
As a modern heating solution, heat pump water heaters produce hot water with much lower energy consumption compared to traditional electric, oil, or gas heaters. In fact, they consume only one-fourth the energy of electric water heaters and one-third that of fuel-based systems. When used on a large scale, they can significantly reduce the overall demand for heating energy in communities.
For example, consider an average urban household that uses 200 liters of hot water at 60°C daily. If using an electric water heater (calculated based on a 40°C temperature rise), the daily electricity consumption is approximately 11.6 kWh, costing around ¥5.3 per day, or about ¥1,925 annually. However, with an air-source heat pump water heater, the daily electricity usage drops to about 2.6 kWh, costing roughly ¥1.53 per day, or around ¥550 per year. This means a potential annual saving of at least ¥1,375 compared to traditional electric water heaters.
A heat pump system consists of four main components: the compressor, condenser, expansion valve, and evaporator. Like a refrigerator, it works by circulating a refrigerant through a closed loop. The refrigerant absorbs heat from the surrounding environment, evaporates, and is then compressed into a high-temperature, high-pressure gas. This heat is transferred to the water via a heat exchanger, where it is released. The refrigerant then passes through the expansion valve, reducing its pressure and returning to a low-temperature, low-pressure liquid state. This cycle continues, continuously heating the water in the tank. The heated water is then circulated through the home’s plumbing system, either for space heating via radiators or for direct use as hot water.
By incorporating these advanced systems into homes and buildings, individuals and communities can not only save money but also contribute to a more sustainable future. Stay tuned for more updates on the latest energy-saving products and innovations.
