From August 20 to 22, 2025, the "CHPC China Heat Pump" 2025 Heat Pump Industry User Ecology Conference hosted by the China Refrigeration Society was held in Tianjin, with the theme of "Innovating the Industrial Chain and Building a New Ecology", bringing together all parties in the industry, academia, research and industrial chain, focusing on the coordination of policies, technologies, and industrial chains, analyzing the innovation path of the whole chain driven by user needs, and helping to seize opportunities to jointly build a green and low-carbon heat pump industry ecology.
In the speech, she first emphasized that viscosity is the core parameter of lubricant selection in heat pump system, which directly affects the lubrication effect and energy efficiency of the system, and needs to be combined with the Stribeck curve to match the working conditions of the heat pump. Then, the different characteristics of lubricants in different scenarios, viscosity stability under wide temperature range conditions and compatibility with low GWP environmentally friendly refrigerants are analyzed, and the reliability of selection is ensured from the dimensions of thermal stability, full life cycle performance, and scenario suitability.
By displaying the Stribeck curve and the four-ball sintering friction experiment, the frictional effect of the base fluid and additives on the lubricant is vividly displayed, and a number of experimental data such as infrared spectroscopy, oxidation resistance test, PVT Daniel diagram, specific heat capacity heat transfer coefficient are used as a basis, and the corresponding lubricant is matched for the heat pump system using different refrigerants under different working conditions, so as to reduce friction loss, improve energy efficiency and extend the service life.
With its continuous innovation in the field of lubrication technology, Jingyi won the 2025 "Outstanding Contribution Brand Award" issued by the China Refrigeration Association to help the development of the heat pump industry ecological chain. This honor is not only an authoritative certification of its technical strength, but also confirms its core role in the professional track of heat pump lubrication.
This heat pump industry user ecological conference is not only a collision of industrial chain wisdom, but also a collaborative start on the road of green and low-carbon transformation. Jingyi takes deep technology cultivation as the pen and scene innovation as the ink, writes professional annotations in the subdivision of lubricants, and paints a new picture of the heat pump industry from "technological breakthrough" to "value symbiosis" with the whole industry with an open ecological attitude. In the future, only by continuing to take root in innovation and coordinating can the temperature of green energy be transmitted to more application scenarios.
