Its development process:
1965, European engineer Healy and others put forward the idea of using condensation heat of water chillers to produce domestic hot water.
At the end of 1970s, the heat recovery technology of water chillers set off the first popularization climax in this area.
In 1980s, European countries promulgated the first step of the performance standard of heat recovery for air conditioning and refrigeration systems to guide the design of waste heat recovery systems.
In 1990s, scientists such as D.M.Count studied the characteristics of heat pump units with heat recovery devices, and made a breakthrough.
In 2003, EK Air Conditioning took the lead in launching the air-cooled heat pump total heat recovery unit in Europe, leading the new direction of heat recovery technology in the European market;
In 2009, Eck Air Conditioning introduced the air-cooled heat pump total heat recovery unit with the most complete control system in China. The water (ground) source heat pump technology of Eck air conditioning is an efficient and energy-saving air conditioning system, which uses solar energy and geothermal energy absorbed from shallow water sources (such as groundwater, rivers and lakes) and soil sources on the earth's surface, and adopts the heat pump principle, which can not only cool and heat, but also provide domestic hot water. The system consumes 65,438+0 kW of energy, and can obtain more than 4kW of cold or heat, thus reducing carbon dioxide emissions. This is a real low-carbon air conditioner.
Water (ground) source heat pump technology is one of the refrigeration and heating modes with the highest energy efficiency ratio in air conditioning system at present, and it has become the most popular air conditioning system. Our government strongly advocates that, according to the policy, all buildings that adopt water (ground) source heat pump technology can get government policy support by reporting to the local government, and the supporting expenses of buildings can be reduced or exempted by 140~200/㎡.
Its development process:
19 12 years, water (ground) source heat pump technology was born in Sweden and obtained the invention patent.
In 1950s, developed countries in Europe and America began to study water (ground) source heat pump technology.
In 1970s, due to the oil crisis and environmental deterioration, the research of water (ground) source heat pump technology developed rapidly.
1978, EK air-conditioning water (ground) source heat pump was officially put into the European market, and quickly gained market praise.
In 2000, Eck Air Conditioning and European DLR Aerospace Industry Company carried out a comprehensive cooperative research on water (ground) source heat pump technology.
In 2009, Ek China introduced the technical achievements of European water (ground) source heat pump and launched the EKSC screw water (ground) source heat pump unit.
In 20 10, EK air conditioner was the first to successfully launch water (ground) source digital multi-connected central air conditioner among many European high-end brands. EKCW series DC brushless fan coil units adopt the latest DC brushless patented technology jointly developed by EUROKLIMAT Group and China Aerospace Science and Industry Group. The leading air treatment technology is adopted to realize the diversified control of stepless speed regulation, and the motor speed is automatically adjusted according to the indoor load change to achieve the best energy-saving effect, which is more than 65% energy-saving than the general fan disk system. Nearly 300 models of the whole series of units are available for customers to choose from.
Its development process:
19 17, Dr. Borgio proposed to replace mechanical brush with rectifier tube, and the basic idea of DC brushless motor was born.
1955 engineer D.Harrison applied for the patent of mechanical brush for the first time, marking the birth of DC brushless motor;
1978, DC brushless motor and its driving module were officially promoted in Europe, which became the hot spot of energy-saving application in Europe.
198 1 year, EUROKLIMAT Group officially promoted DC brushless technology in the terminal field;
1986 engineer H.R.Bohon made a comprehensive and systematic summary of DC brushless technology, marking the maturity of DC brushless technology in theory;
20 10 EK air conditioner and China Aerospace Science and Industry Group jointly developed industry-leading DC brushless motor and control technology, aerospace science and industry, EK patent.
