Recently, the "CHPC · 2025 Heat Pump Industry User Ecosystem Conference", hosted by the Chinese Association of Refrigeration, was grandly held in Tianjin. The conference attracted over 50 industry experts and more than 1,200 heat pump practitioners from all over China to gather together, focusing on the construction of the heat pump industry ecosystem and the path of high-quality development. As a dedicated player in air treatment and energy-saving technologies, Holtop was invited to attend and discuss the future with industry partners.
At this grand event, Holtop, relying on its long-term practice and innovative achievements in the field of energy conservation and emission reduction of heat pump products, won the "CHPC · China Heat Pump" 3rd Member Congress Membership Certificate. This honor is not only a high recognition of Holtop's long-term commitment to technological innovation and promotion of green development, but also an important affirmation of the company's active participation in the dual-carbon goal and its leadership in the industrial transformation and upgrading. Behind this honor lies the mission and responsibility that Holtop has always adhered to, which also injects stronger momentum into the company's continued development.
At the communication site, participants shared practical scenarios in the application of heat pump equipment. From heat pump technologies in cold northern regions to energy-saving applications of waste heat recovery, heated discussions were held around core pain points such as equipment operation efficiency in different environments, adaptability to extreme climates, and long-term energy consumption control. Combining the underlying technical logic of its star products, Holtop's technical team disassembled key solutions in a targeted manner, while extending to the exploration of future industry trends. Through in-depth communication, participants not only solved practical puzzles in heat pump applications, but also gained insight into the innovative direction of green HVAC technologies.
Holtop's Modular Inverter Air-Cooled Chiller (Heat Pump) Units adopt advanced DC inverter technology and integrate a number of innovative technologies in their internal structure. The units can achieve stepless capacity adjustment from 15% to 100%, enabling more precise water temperature control. The ultra-low starting current ensures stable and reliable operation of the units. The precise intelligent defrosting based on multi-variable parameters greatly improves user comfort and meets the cooling and heating needs of different places. The units reach the first-level energy efficiency, with remarkable energy-saving effects.
For cold northern regions, Holtop's Low-Temperature Air-Source Heat Pump Units have obvious advantages. These units adopt EVI (Enhanced Vapor Injection) compressors, matched with advanced high-efficiency heat exchangers and parallel control technology, and have excellent heating performance even in low-temperature environments as low as -35°C. The heating COP (Coefficient of Performance) of the units is as high as 3.64, and the cooling COP is as high as 3.48, meeting the national first-level energy efficiency standard. They can perfectly replace traditional boiler heating, meet the heating needs in low-temperature environments, and have low operating costs, making them an excellent choice for winter heating.
Holtop's Total Heat Recovery Air-Cooled Heat Pump Units are equipped with double-pipe heat recovery heat exchangers, which can 100% recover the condensation heat released during the refrigeration process for hot water production, realizing the reuse of waste heat. The unit control adopts double four-way valves + diaphragm check valves + double electronic expansion valves + multi-solenoid valve control technology, enabling efficient operation in 5 modes. With an IPLV (Integrated Part-Load Value) as high as 7.4, the units not only bring users double improvements in energy conservation and economic benefits, but also are highly consistent with the concept of green and low-carbon development.
The entire series of Holtop's Modular Air-Cooled Chiller (Heat Pump) Units can be intelligently controlled through multi-variable monitoring, with precise adjustment for each refrigeration system. This ensures stable water temperature control and balanced system operation, guaranteeing the efficient and stable operation of the units. Each RS485 interface can control 16 modular units, and up to 8 interfaces can be connected to control a total of 128 modular units. The control system judges the actual frosting condition by monitoring the change rate of the temperature difference between the outdoor temperature and the evaporation temperature, and performs defrosting accordingly, reducing unnecessary energy consumption. The defrosting process does not affect the water temperature, ensuring stable water temperature.
Honor is recognition, but also responsibility. Taking this award as an opportunity, Holtop will continue to adhere to technological innovation and product upgrading, deepen the multi-scenario integrated application of heat pumps and air treatment, and promote the green and coordinated development of the industrial chain. In the future, the company will align its strategy with that of "CHPC · China Heat Pump", and contribute more to green buildings and the dual-carbon goal with more efficient, energy-saving and environmentally friendly air treatment solutions, working together with industry partners to promote the progress of the industry.
