CHAPTER 2. EVALUATION AND IMPROVEMENT2.1. Idea for improvement:

Traditional high pressure light systems rely on electrical energy from the grid,which can be costly and have a significant carbon footprint. To address theseconcerns, we have developed a groundbreaking solution that integrates solar panelsdirectly into the high-pressure light system, enabling it to operate using renewableenergy from the sun.

The solar panels are strategically incorporated into the design of the high-pressurelight system to capture sunlight and convert it into electricity. These panels consistof photovoltaic cells that generate direct current (DC) power when exposed tosunlight.

CHAPTER 3. ENVIRONMENTAL IMPACTS OF PRODUCTS3.1. Environmental impact calculation tool

Ecolizer 2. 0 is an innovative tool that helps users calculate and understand the environmental impact of their daily activities. It provides an in-depth analysis of the user's carbon footprint, water usage and energy consumption. With the help of Ecolizer 2.0, users can identify the areas in which they can make the most impactful environmental changes and make better decisions for a greener future.

Fig 4. Ecolizer 2.0 tool

</div><span class="text_page_counter">Trang 11</span><div class="page_container" data-page="11">

The Ecolizer 2.0 is primarily a tool for designers, helping them toassess environmental product impact and to choose the proper material for each individual application. It is a first step towards ecodesign, but not the only one. Defining a life cycle scenario and determining a functional unit of your product/design are particularly important when using the Ecolizer. For some, the Ecolizer will prove too complex and time-consuming, for others it may not be sophisticated enough. Alternatives are available to fulfil the needs of both types of users.

Ecolizer can be used for different material such as: plastics, wood or metal,…and also canculate the engergy, transport, lights, and electronics components.3.2. Evaluate the effectiveness of changing material.

Hypothesis: To make the 2 products fair, we need some assumptions to make the 2 products about the same frame of reference so that we can get the most accurate calculations with ecolizer 2.0. First, there is no ecolizer for Vietnam, but only for Europe, so we will use European standards to calculate.

In this case, we consider the improved high-pressure and high-pressure streetlightsto be manufactured at Hapulico's factory - Hapulico company has always been one of the leading units in the field of design, construction of lighting works and manufacture of lighting equipment. Hapulico is the unit assigned to manage the lighting system in Hanoi city and is also the first unit to produce urban lighting equipment: columns, lights. Currently, the company's factories are located in Van Lam - Hung Yen and Kieu Ki - Gia Lam. Therefore, we consider the transportationdistance and means of transportation from the factory and the place of installation of both products to be the same, so we will skip the transportation phase.In the end, we will assume 2 products are used for 12 years, 1 time a day, 12 hourseach time.

In short, the product is compared with the following assumptions:Use European standards ecolizer to calculate.

Both devices are manufactured in the same factory, so we consider their distance and means of transportation to be the same. Therefore, we will skipthe transportation phase.

2 products are used for 12 years, 1 time a day, 12 hours each time.

</div><span class="text_page_counter">Trang 12</span><div class="page_container" data-page="12">

In order to see the advantage and disadvantage, we apply Ecolizer 2.0 in 3 phase: Production, Consumption and Recycling. With the assumption given above that 2 products have been brought to the same frame of reference; we will use the method of simultaneous comparison.

As mentioned in chapter 2, we have the main components of high-pressure streetlights as figure below. We should analyze each component and calculate the sum of them in order to take total results.

Fig 5. 3D model of improved high-pressure street lights.3.2.1 Production phase.

We consider common installation equipment such as lamp poles, brackets... of bothnormal and improved devices to be the same. Therefore, we will exclude the components from the calculation.

We have Ecolizer calculation:

Table 3: Consumption phase of simple high-pressure streetlights.We assuming that 1 year has 3/4 of the time there is enough sunshine to power the light bulb and the remaining 1/4 time will use normal electrical energy

We have Ecolizer calculation:

<small>Total = 86724mPt</small>

Since using solar energy for lighting, the improved high-pressure streetlightsare completely environmentally friendly, so the impact on the environment istrivial.

</div><span class="text_page_counter">Trang 15</span><div class="page_container" data-page="15">

Meanwhile, for the improved high-pressure street lamps, after a period of use, the solar collector can be completely reused. I think, the battery can alsobe recycled, but in Ecolizer 2.0 there is no mention of this factor, so we will ignore it.

Table 4: Recycle phase of the improved high-pressure streetlight.From the chart below, we have some comments:

One of the other outstanding advantages of the improved solar high-pressurestreetlight is that it also has the ability to recycle expired materials. The sign (-) here represents the reuse of the material.

3.3. Overall.

Here is the final result:

CHAPTER4: CONCLUSION

Environmental awareness is one of the important responsibilities of the Motorer. In particular, the industry has been causing many negative impacts to the human environment and daily destruction of the Earth. Therefore, modern industry needs to change to be more environmentallyfriendly and preserve the purity of the Earth.

This project is an interesting experience for us who will become an enginneer in the future, to be more aware of environmental protection, practice calculation and consideration in product design and manufactureto ensure our products still maintain and develop well their inherent advantages while limiting negative impacts on the living environment.

This subject has been an interesting and useful experience for us. The knowledge here is not too new, but it has been analyzed deeply and gives us amore multi-dimensional view of the Motorering profession. We would like to express our deep gratitude to Assoc. Prof. PhD. Nguyen Thi Hong Minh was dedicated and brought us quality and practical lessons.
