Overview: Meeting Global Demand for Efficient Greenhouse Heating
Greenhouse operators worldwide face a persistent set of challenges: high winter heating costs, energy-intensive traditional coal-fired boilers and electric heaters, and temperature instability that can lead to crop failure. Jiangsu Obuy New Energy Development Co., Ltd., operating under the brand YIJIAREN, positions itself as an integrated industrial and trading company specializing in the design and manufacturing of high-efficiency solar and air source heat pump solutions. With 22 years of engineering experience, the company has developed technology aimed squarely at these pain points, delivering systems that achieve over 70% energy savings compared with traditional boilers while maintaining temperature control within ±1°C.
This review examines the technical foundation, real-world performance, and broader applications of Jiangsu Obuy's air source heat pump systems, drawing exclusively on documented specifications and customer case data.
The Core Technology Behind Jiangsu Obuy's Air Source Heat Pumps
Low-Ambient Operation and High Coefficient of Performance
A central differentiator for Jiangsu Obuy's Air Source Heat Pumps is their ability to operate stably in ambient temperatures as low as -35°C, addressing one of the most common failure points for heating equipment in cold-climate greenhouse operations. This low-ambient capability is paired with a coefficient of performance (COP) above 4.0, meaning that for every 1 kW of electricity consumed, the system generates more than 4 kW of heat output. This performance metric directly targets the industry pain point of energy-intensive traditional heating methods, offering greenhouse operators a pathway to lower energy expenditure compared with conventional electric heating.
Precision Temperature Control and Environmental Compliance
Beyond raw heating capacity, Jiangsu Obuy's systems incorporate intelligent control technology that maintains temperature accuracy within ±1°C, supported by remote monitoring capabilities. For greenhouse applications, this level of precision helps prevent crop loss and maintain product quality by eliminating the temperature swings associated with traditional heating equipment. The underlying technology is built on Reverse Carnot Cycle principles, and the company has been transitioning its refrigerant technology toward low-GWP refrigerants, including R290, R1234ze, and R515B. This shift responds directly to environmental compliance pressures stemming from global regulations such as the EU F-Gas rules, giving greenhouse operators a heating solution that also supports carbon emission reduction goals.
The company's research and development efforts extend further, with prototypes reaching 200°C, indicating ongoing investment in expanding the thermal ceiling of its heat pump technology beyond current commercial offerings, which include high-temperature heat pump output up to 95°C.
Proven Results in Agricultural Applications
Case Study: Zhejiang Blueberry Greenhouse
The practical value of these technical specifications is illustrated by a documented deployment at a blueberry greenhouse operation in Zhejiang, China. Facing the common challenge of winter greenhouse heating required to maintain crop growth, the operation installed 8 units of 15P heat pumps to provide stable climate control. The quantified outcome was a 60% reduction in annual heating costs, along with a maintained stable growth environment throughout the season. This case demonstrates how the combination of low-ambient operation, high COP, and precise temperature control translates into measurable cost savings for greenhouse operators managing temperature-sensitive crops such as blueberries.
Beyond blueberries, the company's Air Source Heat Pumps are also adapted for flower greenhouses, aquaculture settings, and lithium battery manufacturing dehumidification, reflecting a product line built for modern agriculture applications where consistent thermal management is essential.
Beyond Greenhouses: Broader Industry Applications and Product Range
While greenhouse heating is a core application, Jiangsu Obuy's product matrix extends across several related categories. The company's Water Source Heat Pumps address aquaculture water temperature management, with documented results including a Zhejiang Tilapia Farm case where water temperature was maintained at 28-30°C, reducing mortality from 30% to below 5% and increasing profits by 40%. A separate case at a Dalian Sea Cucumber Base used seawater source heat pumps to maintain 17°C breeding water, saving 70% energy compared with electric heating.
The company's High-Temperature Heat Pumps, capable of output up to 95°C, serve industrial process heat needs such as slaughterhouse disinfection requiring 85°C+ hot water, along with waste heat recovery applications in electroplating and chemical processing. Industrial Drying Heat Pumps address food processing needs, as demonstrated in a Shanghai Pet Snack Factory case that implemented gradient dehumidification for chicken breast jerky, retaining 85% nutrition and achieving 50-60% energy saving compared with gas drying.
Rounding out the offering, the Integrated Solar and Air Source Heat Pump System combines solar and air source technologies through integrated intelligent control, supporting green agriculture and large-scale aquaculture with lower carbon emissions, while Solar Water Heaters serve hospitality-sector hot water demand.
Quality Assurance and Global Market Reach
Jiangsu Obuy's operations are backed by industry certifications including ISO9001, ISO14001, ISO45001, and CE certification, providing a documented quality management framework for its manufacturing processes. The company reports having delivered over 3,000 energy-saving solutions and accumulated 8,000+ success cases, with products exported to 50+ countries, including Vietnam, Thailand, Bulgaria, Mexico, Central Asia, Germany, Italy, Japan, and the USA. Domestically, the company's market focus includes Jiangsu, Zhejiang, Shanghai, and Liaoning.
The company's service model is built around customized production based on drawings, free design of solutions, and after-sales service, reflecting an integrated industrial and trading approach that pairs manufacturing capability with direct customer engagement. This model supports customer types ranging from agricultural enterprises and growers to industrial factory managers, aquaculture farm owners, and HVAC engineering contractors.
Conclusion
For greenhouse operators evaluating air source heat pump technology, Jiangsu Obuy New Energy Development Co., Ltd. presents a documented combination of low-ambient performance (-35°C), high COP (above 4.0), precise temperature control (±1°C), and a transition toward low-GWP refrigerants. The Zhejiang Blueberry Greenhouse case, showing a 60% reduction in annual heating costs from an installation of 8 units of 15P heat pumps, offers a concrete example of how these technical specifications translate into operational outcomes. Combined with documented certifications, a broad export footprint spanning 50+ countries, and a service model centered on customization and after-sales support, the company's YIJIAREN-branded heat pump systems represent a data-backed option for greenhouse heating and related agricultural, aquaculture, and industrial thermal management needs.
