Since then, in the rail transit industry, a bidding model with "indicator delivery" is formed. Ningbo Metro Xingzhuang Road Station has put forward high bidding requirements for energy efficiency indicators 6.5. After 4 years of advancement, Tianjia and Fugica upgraded this innovation technology to "Data -based rail transit underground station super high -efficiency and low -carbon intelligent environmental control system", and was successfully used in Ningbo Metro high -efficiency machine rooms.

Some people in the industry pointed out that the construction of high -efficiency computer rooms involved in various links such as computer room design, equipment procurement, construction, commissioning, commissioning to operation. There are only 5.5 or even lower. "Xingzhuang Road Station has stabilized a complete refrigeration period. Nowadays, the landing service is more than half a year. Its energy saving effect is geometry?

Many HVAC, environmental protection practitioners, and architectural owners wait and see. Can this top plan that once appeared on the award list can withstand the test of time and successfully achieve the new "increase" new leap? Is the huge high -efficiency environmental control machine room worthy of replication and promotion in the entire subway system and even the entire industry?

SCOP6.9 leads the "building energy conservation revolution"

After project reports, experts inquiries, discussing resolutions, etc., the evaluation committee experts unanimously identified: "Data -based rail transit underground stations ultra -efficient and low -carbon intelligent environmental control system", its refrigeration machine room system operating energy for the annual operation of 6.9 or more, air -conditioning is full The system operates more than 4.3 throughout the year. The appraisal committee believes that "the application of the project's wind and water system all -frequency conversion and blockchain technology is the first in the industry and the project results have reached the international leading level."

This means that the Ningbo subway ultra -efficient computer room system jointly undertaken by the three major brands under Tianjia, Fugica, and Tuyou under the Skyfield system has achieved a leap from 6.0 to ultra -efficient 6.93. The legs have been used to Scop7.0; the technology used by its "data -based rail transit underground stations based on data -based trust" technology has achieved significant results. Precise, complicated construction and other industries, while introducing blockchain data encryption and transmission technology, the establishment of a data management platform, making energy -saving data unable to tamper and transparent and credible. Its land application potential will lead the new round of energy -saving and emission reduction technology changes in the rail transit industry, helping to achieve the early realization of the green urban rail goals.

Compared with China's average refrigeration machine room comprehensive energy effect, the application of the innovative technology of the project has enabled the comprehensive energy ratio of high -efficiency refrigeration machine rooms to achieve a leap from 3.5 to 6.93, with an energy saving rate of more than 49%.

The "breakthrough move" of the three parties to build a credibility platform

Li Xinmei, general manager of Fugica, introduced that the pilot Ningbo Metro high -efficiency environmental control computer room project broke the traditional model of the original environmental control system equipment and the system "each politics". While reducing the overall pipeline resistance, the equipment in the system can be coordinated to operate, and ultimately the above -mentioned ultra -high energy effects are achieved.

It is reported that the high -efficiency environmental control computer room uses a full -frequency frequency control strategy, and the high -energy efficiency equipment such as the frequency conversion magnetic suspended cold water units, the large and small system air -conditioning EC inverter fan, and the cooling tower perm Magnetic synchronization motor. In addition, the circulating water pump and air conditioner back to the exhaust device are all adopt the frequency conversion control strategy, combined with intelligent comprehensive energy -saving control technology, to maximize energy saving energy consumption, and accumulate data and experience for the transformation of the module of the rail transit air conditioning system. Construction and application. "Data -based rail traffic underground station ultra -efficient low -carbon intelligent environmental control system" review site "

Among them, the biggest core advantage is the three -party co -building credibility platform created by heaven. The construction of Tianjia and Fugat through blockchain data transmission and encryption technology and enhance the credibility of energy -saving data. All the data is directly on the chain and stored in the alliance chain server. The data is jointly managed by the customer, the integrator, and the national authoritative testing institution to build a three -party credibility platform; , Advocating true and credible indicators to be visible to integrity.

Tianjia is the first company in the industry to propose a "three -party public credibility platform". Is the customer's care and consumption reduction problem solved, and whether environmental protection projects have achieved actual results? Answer these questions requires comprehensive and objective evaluation of the operating quality and efficiency of the HVAC. Therefore, customers must be allowed to participate and introduce third -party supervision to ensure that the data is disclosed and truly effective.
