Practical Application of Heat Pump Technology Across Industries

It is not only a powerful demonstration of an enterprise's technological strength but also provides a practical model for policy implementation and technology application within the industry. EVE has always been grounded in core technology R&D, building a full-chain innovation system covering "compressors, complete units, and systems." Its heat pump products have formed three core sectors: civil heating, industrial heat supply, and agricultural energy conservation, with multiple technical indicators setting new industry records.

* In the field of civil heating * , EVE has developed a full range of products suitable for different climate zones, centered around its core three-cylinder, two-stage variable displacement compressor technology. Certified as an "internationally leading" technological achievement, this compressor enables stable operation across a wide temperature range from -35°C to 54°C. It delivers non-attenuated heating performance at -15°C and can raise indoor temperatures to 25°C at -35°C without requiring auxiliary electric heating. Compared to traditional heat pumps, it increases heating capacity by 20% and achieves a Coefficient of Performance (COP) of over 2.1. Leveraging this core component, EVE's residential heat pump units, covering a capacity range of 8-32kW, have been widely adopted in clean heating projects in northern China. In just one county-level heating project, it serves 12,000 households, reducing winter energy consumption by 65% compared to coal-fired boilers and cutting annual carbon emissions by 8,900 tons. On the commercial side, the variable frequency modular units, with a single-module heating capacity of 330kW and the ability to start at ultra-low temperatures of -37°C, have become the preferred solution for large building heating. In the Tianjin Longju Life Plaza project, it provides combined cooling and heating services for a 21,000㎡ commercial complex, achieving a system energy saving rate of 43.5% and saving over 2 million yuan in annual electricity costs. Furthermore, EVE's patented Constant Heating Defrosting Technology solves the industry-wide challenge of frequent defrosting in the Yangtze River Basin during winter. It enables continuous operation without shutdown during an 8-hour defrosting cycle, keeping indoor temperature fluctuations within 3°C. This provides an efficient heating solution for areas in southern China without centralized heating.

The industrial heating sector represents a core breakthrough area for EVE's heat pump technology. Its high-temperature heat pump products now achieve full temperature coverage, ranging from 120°C industrial hot water to high-temperature steam below 200°C. Addressing the heating demands of industries such as petrochemicals, food processing, and pharmaceuticals, Gree has launched a 10MW-class permanent magnet synchronous variable frequency centrifugal heat pump unit. With a single-unit heating capacity of 4.8MW and an average system COP of 3.82, this technology was applied in a geothermal utilization project at an oilfield wastewater station. It successfully recovered waste heat from 33°C oilfield wastewater, converting it into 75°C high-temperature hot water for tank farm insulation and plant heating. This results in annual savings of 12,000 tons of standard coal and a reduction of 32,000 tons of CO₂ emissions. The even more industry-disruptive 150°C ultra-high-temperature centrifugal heat pump unit can directly generate industrial steam, reducing operating costs by 50%-70% compared to traditional gas boilers, with a payback period of only 2-3 years. It has already been deployed at a new energy battery company in Hefei, simultaneously supplying 7°C low-temperature chilled water and 130°C high-temperature hot water. This meets the complex energy demands of processes like battery coating and hot pressing, achieving a measured system COP of 3.13 and an annual carbon reduction of over 5,000 tons. In the steel industry, EVE's low-grade waste heat recovery project for Anshan Iron and Steel Group utilizes two 10MW heat pump units to recover 30°C industrial waste heat. After raising the temperature to 65°C, it meets the heating needs of an 180,000-square-meter plant area, saving 1.8 million cubic meters of gas consumption annually. This project has become a benchmark case for industrial waste heat recovery.

In the field of agricultural energy conservation, EVE has specifically developed two major product series: heat pump drying and greenhouse heating. Addressing the pain points of high energy consumption and high pollution in the drying of agricultural and sideline products, EVE's air-source heat pump dryer utilizes two-stage enthalpy-increasing variable frequency compressor technology. It achieves precise temperature control between 30°C and 80°C and humidity control accuracy of ±5%. In the tobacco curing project in Longyan, Fujian, compared to traditional coal-fired curing, it reduces energy consumption by 70%, increases the rate of high-quality tobacco leaves by 15%, and saves over 20,000 yuan annually per curing barn. In greenhouse applications, EVE's water-source heat pump units, integrated with photovoltaic systems, provide stable heating for the Zibo Smart Agriculture Base in Shandong. The temperature inside the greenhouses is maintained between 18-22°C during winter, saving 85% energy compared to traditional electric heating. This has boosted vegetable yield per mu by 30%, achieving low-carbon and efficient agricultural production. Furthermore, products like EVE's water-source heat pumps and pool-specific units further enhance scenario coverage, forming an all-encompassing "land, sea, and air" heat pump application ecosystem. Notably, EVE's innovation in system integration is equally leading. Its "Integrated Flexible PV-Storage-Heat System" deeply integrates heat pumps with photovoltaic and energy storage technologies, achieving closed-loop management of energy production, storage, and utilization. In a centralized heating project for a village in Hebei, this system meets the heating needs of 500 households, achieving a renewable energy utilization rate of 82% and a winter electricity price as low as 0.2 yuan/kWh. Concurrently, the Taishan Building Control System, equipped with AI algorithms, enables intelligent full-lifecycle operation and maintenance of heat pump units. By monitoring real-time operating data and dynamically optimizing operational parameters, it improves the system's comprehensive energy efficiency by 15%-20%, reducing full-lifecycle costs for users.
