The energy saving system seeks for the overall coordinated control of the main engine, circulating pump, cooling tower and terminal system, and scientifically realizes the overall maximum COP control, real-time intelligent regulation and efficient operation of the central air-conditioning system under variable load.

 

(2) Environmental protection/energy saving benefits generated by this technology

 

A, this system is A complete set of hardware, software, integrated system, to form A complete set of central air conditioning, comprehensive regulation, water circulation wind circulation system, using artificial intelligence technology, changes in working condition, can automatically adapt to, make the outside of the compressor condition is always in the best state, and maintain optimal COP conditions of central air conditioning system for A long time.

 

B. The system is divided into two control subsystems: "circulating water and cooling tower" and "indoor fan".

 

C, advantages: can achieve year-round construction, does not affect refrigeration.

 

D. This technology makes full use of the cold volume of the natural environment and carries out non-contact heat exchange to obtain the natural cold volume and serve the system. In regions with distinct seasons, it is expected to reduce the running time of the compressor by 30% to 40% every year.

 

E. At least 3 different forms of natural refrigeration systems can be provided for different working conditions.

 

F. The "intelligent cold storage" technology of Time Science and Technology is to use artificial intelligence technology to make the best decision and accumulate the appropriate cold quantity by considering meteorological conditions and cold quantity conditions.

 

G. With this technology, energy costs can be reduced by 20% to 60%.

 

(3) Technical advantages

 

Air compressor system energy saving technology, circulating water system energy saving technology and central air conditioning system energy saving technology are combined with software and hardware control, its technical advantages are as follows:

 

Fully intelligent control, ensure the safe and stable supply of pressure flow, improve the reliability of the system, save human resources;
