**Editor's Note:** To help readers better understand new energy-saving technologies and innovations, the City Energy-Saving Monitoring Technology Service Center has selected a range of products to showcase in our "Energy-Saving Products Live Show." Each week, we will introduce different product categories, explain the science behind them, and provide details on upcoming exhibitors and their latest offerings.
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. These systems are now widely adopted by people of all ages who are looking for more efficient and cost-effective heating solutions.
As a modern heating solution, heat pump water heaters produce hot water with much lower energy consumption compared to traditional electric or gas heaters. In fact, they use only about 1/4 the energy of conventional electric water heaters and 1/3 that of gas-powered systems. When used on a large scale, they can significantly reduce the overall demand for heating energy in communities.
For example, consider a typical urban household that uses 200 liters of 60°C hot water per day. If using an electric water heater, the daily power consumption would be around 11.6 kWh, costing approximately ¥5.3 per day, or about ¥1,925 annually. However, with an air-source heat pump water heater, the daily electricity usage drops to around 2.6 kWh, costing about ¥1.53 per day, totaling roughly ¥550 per year. This means a potential annual saving of at least ¥1,375.
The heat pump system consists of four main components: the compressor, condenser, expansion valve, and evaporator. Similar to 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, returning to a low-temperature, low-pressure state, and the cycle repeats. This continuous process efficiently heats the water in the tank, which is then circulated through radiators or directly supplied as hot water for daily use.
By adopting heat pump technology, households not only save money but also contribute to a more sustainable future by reducing energy waste and carbon emissions.
