Ankerui Electric Introduction

Ankerui Electric Co., Ltd. [stock code: 300286.SZ] is a small number of domestic leading providers of intelligent power monitoring, power management, electrical safety, intelligent lighting systems and products for smart grid customers. One of the companies.

Shanghai Jiatang Electronic Development Co., Ltd. is the holding company of Ankerui. It is a high-tech enterprise recognized by Shanghai Science and Technology Commission, Shanghai Finance Bureau, Shanghai Municipal State Taxation Bureau and Shanghai Local Taxation Bureau. It was established in 2000. In the month, the company's main products are: replacement of neon LED waterproof module, LED high-power module, and large, low-power LED lighting products. It integrates R&D, production, sales and service into one, forming an industrial chain from chip packaging, module integration, lighting application and lighting engineering. It is one of the few state-level contract energy management companies in Shanghai.





Underground parking garage lighting status and reasons for renovation

First, the status quo of parking lot lighting

Due to the limited location of the underground parking garage, natural lighting is relatively poor, so the lighting problem is often the focus of the property company, mainly in the following aspects:

1, lighting electricity costs are higher, general garage lighting needs 7 * 24 hours of uninterrupted lighting, the total annual electricity bill is considerable;

2, due to the relatively large number of garage lighting fixtures, large maintenance workload, high replacement cost of lamps, is also a major difficulty in property work;

3, the traditional lighting control is generally manual split control, the control method is relatively simple, the lighting of the lights is also more troublesome;

4. In order to save lighting costs, some properties will reduce the number of lighting channels to save electricity costs, but at the same time, it will lead to a reduction in garage illumination, affect monitoring effects, increase parking risks and other safety issues, and increase management difficulty;



Underground parking garage lighting conventional lighting status:

1, using the traditional 1.2M fluorescent lamp, power 36W, about 3350LM;



2. The control method generally adopts splitting and manual switch control;

Second, the reasons for the transformation

In response to the national energy conservation and emission reduction call, the goal of intelligent lighting and green lighting has been achieved, and at the same time, the electricity company's electricity expenses, labor and management costs have been reduced, and finally a win-win situation has been achieved.



Intelligent lighting renovation program description

First, the general requirements for parking garage lighting standards

According to the design requirements of "Architectural Lighting Design Standard GB 50034-2013", the garage illumination requirements are as follows:



Due to the short residence time of the garage people, the lower requirements such as contrast color development, and the relatively uniform specifications of the lamps, the lighting renovation is relatively simple.

Second, the basic principles of transformation and the ultimate goal requirements

1. Use the original lamp line and mounting bracket to avoid large-scale line transformation;

2. Maintain the original illumination standard, reduce power consumption, and achieve energy saving;

3, the use of green lighting products, does not contain toxic and hazardous substances, reflecting the concept of environmental protection;

4. Combine the original manual branch control method, increase the intelligent control mode, realize infrared control, time control, illumination control, etc.

5, the use of long-life LED lamps, lighting life is not less than 50,000 hours, greatly reducing maintenance costs;

Third, the specific intelligent lighting renovation program

Direct replacement of lamps

1. Ground and underground curved channel lights (flood lights)



Replace the conventional 250W metal halide floodlight

2, garage lighting (straight tube lights)



Replace the conventional 36W+4W (rectifier) ​​fluorescent lamp

Fourth, the control system transformation

1. The ground part channel luminaires are combined according to the degree control and time control mode, but the illuminance priority mode is controlled, and can also be manually opened.

2. Some properties of the garage can be set according to different time periods. When the lights are busy, the lamps are all lit up. When the vehicles are less, the interval between the lamps is bright. In the middle of the night, except for the fire and evacuation areas, the lights are always bright. Some of the luminaires implement infrared control. When the personnel flows or the vehicle moves, the luminaires are turned on at the same time to improve the security function. For example, the community can be divided into up, off hours and night lighting modes. Shopping malls and supermarkets can be divided into business hours lighting mode, and non-business hours lighting mode, etc., can be freely set according to demand.

3, the lamp can also achieve infrared control function

4. Set the main switch on different floors to control the floor separately.

V. Benefit analysis before and after transformation

Compare the following table before and after the transformation:

Direct energy efficiency analysis



After the renovation of the lighting, the single lamp directly saves electricity costs: the garage tube lamp saves 191.32 yuan/year, and the channel floodlight is about 1471.68 yuan/. Due to the use of long-life LED lamps, the cost of lamp replacement and maintenance is reduced, and the intelligent control method reduces the lighting time. The comprehensive energy saving rate can reach more than 70%.

6. Introduction to contract energy management mode

Contract energy management, widely known as EMC (Energy Management Contracting) in China, is a new energy-saving mechanism based on market operation developed in western developed countries in the 1970s. The national standard for contract energy management is GB/T24915-2010 "Technical Specifications for Contract Energy Management". The state supports and encourages energy-saving service companies to carry out energy-saving services under the contract energy management mechanism, and enjoys preferential policies for financial incentives and income tax exemption.

2, step details

(1) Project investigation: The company sent engineers and technicians to the project site for on-the-spot investigation. According to the lighting environment of the project site, the brightness of the lamps, the needs of the owners, etc., the project was initially judged and the project was determined to directly replace the lamps. Or provide the owner with the best lighting renovation plan according to the needs of the enterprise. Calculate the total amount of skills according to the actual situation



(2) Project revenue sharing

The general EMC project is a “benefit sharing type” project. The contract period is generally 3-5 years, which is defined by the amount of investment, and some may be 5-10 years. The two parties share according to the amount of electricity saving. Taking the energy-saving renovation of the garage as an example, the property company has zero input, so the amount shared by the energy-using units in the previous period is relatively low. Therefore, in order to make the investment and the proportion of the program directly proportional to the trend, generally on the EMC contract, the price marked is the market price of the price list, combined with the contractual period, multiplied by a certain maintenance factor of 1-3%.

(3) Calculation method of division

According to the total energy saving of the lamps before and after the replacement, the energy saving amount is calculated uniformly according to the illumination duration agreed by both parties, and then shared according to a certain proportion every year. For example, the contract period of 3-5 years can be divided into three stages, 9:1/month, 8:2/month, 6:4/month, which can be adjusted according to the situation. Considering the factors such as RMB depreciation, general contract recovery cannot be Less than 150% of the investment amount.
