Focusing on the frontiers of the industry, the heat pump drying and freezing technology exchange meeting was held in Songshan Lake, Dongguan

Songshan Lake in early autumn is full of greenery and waves. Under the warm autumn sun, the "Heat Pump Drying and Freezing Technology Exchange Conference" was held as scheduled on October 21, 2020 at the CIMC Zhigu International Conference Center in Songshan Lake, Dongguan. This grand event was hosted by Zhejiang Sanhua Trading Co., Ltd. and undertaken by Dongguan Sanjiang Refrigeration and Heating Equipment Co., Ltd. The conference fully focused on the frontiers of heat pump industry technology, and held a Sanhua product and technology exchange meeting.

The leading guests invited to attend this grand event included Zhao Hengyi, Executive Deputy Secretary-General of the Heat Pump Special Committee of China Energy Conservation Association, Chen Zaicheng, General Manager of Dongguan Sanjiang Heating Equipment Co., Ltd., Cao Danhui, Director of Sanhua Marketing Department, and Ding Shaoqing, Head of E-commerce of Sanhua Marketing Department Wait. Nearly a hundred people including professional media in the heat pump industry and representatives of heat pump manufacturers also came to the event.

The meeting was presided over by Chen Zaicheng, general manager of Dongguan Sanjiang Refrigeration and Heating Equipment Co., Ltd., and Mr. Zhao Hengyi, deputy secretary-general of the Heat Pump Committee of China Energy Conservation Association, was invited to address the meeting. Deputy Secretary-General Zhao first analyzed the market prospects of heat pump drying from the perspective of national energy structure, indicating that the heat pump drying market has great potential, especially in industrial and agricultural applications, such as tobacco drying and grain drying. Subsequently, Deputy Secretary-General Zhao said: Drying is a complex field, and heat pump companies need to focus on a certain sub-field to do precision and specialization for drying. Finally, he emphasized that there is a big difference between heat pump drying and cold, warm and hot water. In the heat pump drying industry, the company's technology and product quality must be excellent, otherwise it will not only be difficult for the company to conduct business, but the reputation of the entire industry will also be seriously affected.

At the Sanhua product and technology exchange meeting, Cao Danhui, the director of Sanhua’s marketing department, first introduced Sanhua’s valve products used in air source heat pumps, including four-way reversing valves, solenoid valves and electric ball valves, throttle valves and controls. Devices, on-off/overhaul, containers and heat exchangers. Specific to the part of the four-way reversing valve, Cao Danhui focused on the advantages of the G-type stainless steel four-way valve, such as more stable raw material costs, improved product reliability and production efficiency. Compared with similar products, Sanhua's stainless steel four-way valve can be used in frequency conversion products, and the internal leakage under partial load is lower than that of similar products, and the energy efficiency can be increased by about 5%; moreover, Sanhua's new stainless steel valve can help in overall optimization The R32 system has just the right capacity and smaller pipelines. Next, Cao Danhui also gave a detailed and solid introduction to the four-way valve selection principle, installation technology and piping design.

In the solenoid valve and electric ball valve section, Cao Danhui first introduced the EVB electric ball valve, and focused on the analysis of the advantages of the EVB electric ball valve, including automatic control, no risk of external leakage, long service life, two-way flow and closing, lower pressure loss, and low pressure loss. Internal leakage, large flow range, low heat loss, etc. Subsequently, Cao Danhui also gave a professional explanation on the application of EVB electric ball valve in heat pump drying system, electronic expansion valve application solution, pressure sensor, ice maker/ice cream maker system solution and other knowledge areas.

With the rapid development of the e-commerce era, all walks of life have increased their emphasis on online marketing. This trend has become more obvious after the outbreak of the epidemic in 2020. In order to open up online marketing channels, at the end of this exchange meeting, Ding Shaoqing, head of the e-commerce department of Sanhua Marketing Department, announced that the "Sanhua Online Mall" has officially started trial operation. You can browse products, select models, and inquire on the mall. Operations such as, purchasing, etc. are very fast and convenient. Manager Ding said that Sanhua will make full use of online and offline channels for promotion and sales, so that Sanhua's products can serve more heat pump companies.

As a global leader in the production and development of HVAC components and parts, Sanhua attaches great importance to technological innovation, continuously improves research and development capabilities, and develops new products with independent intellectual property rights, high technology content, energy saving and environmental protection, and technological innovation Lead the development of the industry and promote the continuous progress of heat pump companies.

Under the background that the government advocates energy conservation and environmental protection and consumers pay more and more attention to food safety, heat pump drying is increasingly favored by the market due to its high efficiency, energy saving, environmental sanitation, and good drying quality. It is growing against the trend in the post-coal-to-electricity era. , Has become a field where heat pump companies are competing to invest. Sanjiang Refrigeration and Heating will work with Sanhua high-quality valves to continue to inject the latest technological energy into heat pump drying products, and help the heat pump drying industry to further develop and grow!
