At present, the northern region of China is entering a new round of heating season, 'coal to electricity' and other heat pump heating keywords appear again in high frequency in people's lives. By 2017 China Household Electrical Technology Conference opportunity, GMCC solemnly released ' Core 'heat pump heating compressor for new products.The compressor to achieve low-temperature heating energy efficiency soared 26%, to overcome the "coal to electricity" in the process of promotion, conditions and other difficulties.
GMCC compressor heat at low temperature road
GMCC devoted itself to research and development after nearly 10 years of assisting the army with coal-to-electricity, and has gone through technological changes and development in three periods.
The first stage is the successful development of varactor technology. When GMCC achieves low-temperature heating, the capacity of the compressor can be greatly increased, the heating capacity can be increased, and the running noise of the compressor can be effectively reduced.
The second phase through the development of jet enthalpy technology and high-speed frequency conversion technology, improved the previous generation, unique check valve big capacity jet technology, energy efficiency, heating capacity increased by 20% to 30%.
By the third stage, GMCC's R & D team creatively integrated the three technologies of variable frequency, variable capacity and enthalpy of jet engines into a full-scale coupling to launch GMCC heat pump special compressor with stable and good heating effect. Now, Chisel 'compressors are becoming a powerful propeller of the North's coal-to-electricity process with their three major technologies.
Three major technologies to overcome 'cold heat' difficulties
Coupling technology First, the varactor technology to adapt to jet applications GMCC the original vane tail pressure switch to the internal suction pressure switch, the use of two-stage throttle intermediate jet technology, the use of flasher gas-liquid separation, to achieve the effect of increasing enthalpy, And at low and medium pressure side of the compressed air jet mixing cooling, high pressure normal compression mode to improve the compressor displacement, to achieve low temperature environment to quickly enhance the heating capacity of the test data show that GMCC 'heat Chi core' heat pump Dedicated heating compressor maximum pressure ratio of 16.3, at -25 ° C in the low temperature can be efficient operation.

Coupling technology Second, through the cylinder jet to the separator jet, to achieve efficient jet technology. GMCC 'Chi Chi core' heat pump heating compressor with flexible jet technology, intelligent adaptation to system conditions, enabling a full range of high efficiency, high flow Jet, easy to adjust the system conditions Easy to control and does not produce jet back problems, a wide range of compressor operation At the same time, GMCC sophisticated electronic expansion valve throttle control, intelligent defrost control technology to ensure that the compressor In -25 ℃ in the cold can achieve the purpose of efficient defrosting, heat pump equipment to improve energy efficiency in harsh climates to meet the heating needs of various conditions.

Coupling technology Third, the varactor technology and jet technology coupling GMCC 'heat Chi core' heat pump heating compressor flexible adaptive system and flexible jet technology to achieve energy efficiency, effectively reducing the heat loss under severe conditions, to achieve Efficient, high heating capacity, rapid cooling, ultra-low temperature mute and other effects. GMCC self-developed 'intelligent frequency + jet enthalpy' technology to achieve heating and efficiency 'double high', 'Chi Chi' compared to ordinary speed products The heating efficiency has been improved by over 26% to ensure the heating water needs in the northern low-temperature environment and at the same time, a more energy-efficient and environment-friendly heating effect has been achieved.

Coupling technology with electronic control solutions to achieve 'four unobstructed'
GMCC 'heat Chi core' heat pump heating compressor with winter heating, summer cooling powerful features in the three major coupling technology support, GMCC 'heat Chi core' heat pump heating compressor efficient and stable, to achieve 'low temperature unimpeded' , 'Efficient and unobtrusive', 'Unobstructed working condition' and 'Unobstructed matching' effect, excellent start-up under -25 ° C low temperature conditions; Equipped with flexible intellectual adaptation system to make the compressor energy efficiency rise to effectively solve the heat loss under severe cold; Operating range Wide, can apply a variety of harsh conditions; electronic control support for heat pump companies to provide one-stop frequency conversion heat pump technology system solutions to help upgrade the industry as a whole. At the same time, GMCC joint heat pump companies in each region have a person in charge Technical guidance and after-sales service work, equipped with enough related accessories, to ensure the first time residents in need to provide professional and specific solutions.
