On April 9, 2018 China Refrigeration Exhibition was opened at the China International Expo Center in Beijing. In the morning, GMCC, the world's largest manufacturer of compressors for HVAC and refrigeration equipment, issued the 'Heat Chipping Core' - North Coal to Electric Heat Pump Heating dedicated compressor (for hot air fan).
In northern China, the use of coal-fired heating in large areas in winter has become a major cause of haze for many years. Facing the severe air pollution situation, it is imperative to change the energy structure. In order to fight the blue skies, China is accelerating the northern region. Coal has changed the pace of clean energy. The Chinese government has clearly proposed that comprehensive management of coal will be fully implemented to promote clean heating in the winter in the northern region, and to replace electricity with coal, to replace coal by more than 3 million, and to eliminate all built-up areas in urban areas above the prefecture level. Coal Small Boiler. To increase the ultra-low emission and energy-saving transformation of coal-fired power plants, the eastern and central regions will be completed in the next two years respectively, and the western region will be completed in 2020.
In the process of coal reforming clean energy, heat pump heating has become a technology choice that has received extensive attention and support from the government and industry. To meet market demand, GMCC has invested special funds in recent years to develop 'coal-to-electricity' related product development. In 2017, the company launched the special compressor for heat pump heating of hot water machines. This year, it introduced related products for hot air fans.
In the northern regions, the cold weather in winter poses a constraint on the heating efficiency and heating efficiency of the heat pump. This is not only a major pain point for heat pump heating users, but also a technical problem faced by the heat pump heating compressor industry.
Zheng Liyu, General Manager Assistant and Director of R&D Center of GMCC, introduced the “Heatcore” special heat pump compressor (for hot air blowers)
Zheng Liyu, GMCC's assistant general manager and director of the R&D center, said that the GMCC's official release of coal-fired electric heat pump heating compressors (hot air blower) products adopts GMCC's self-developed jet booster technology, which can effectively enhance the low temperature of compressors. Thermal function, to achieve -25 °C cold and efficient heating.
'Heat core' - North coal to electric heat pump heating compressor (heat fan)
According to him, 'Heat core' - North coal to electric heat pump heating special compressor (hot air fan) with low temperature, unrestrained, high efficiency, unrestrained, unresisted multiple technical advantages, can achieve a large pressure ratio of 16.3, -25°C ultra-low temperature start, outlet air temperature up to 37°C, outlet water temperature up to 60°C; adopting flexible and intelligent adaption system, low-temperature heating capacity increased by 26%; wide operating range to adapt to a variety of harsh working conditions; effective cooling in summer, COP ≥ 3.75, and the cooling energy efficiency does not decay.
At the conference, Hu Wangyang, deputy secretary-general of the China Refrigeration Association, and Zheng Liyu jointly unveiled the secret of the 'Heat Core' compressor.
Zheng Liyu further stated that the GMCC heat pump heating technology system adopts the jet boosting frequency conversion technology. The system is simple and reliable, easy to implement, and does not require major changes to the conventional heat pump system structure. It is currently an economic and effective improvement program to improve the low-temperature heating capacity of the system.
