Lecture Notes
Lighting and Appliances
Anything that draws electrical power is referred to as a load. Part of weatherizing a home includes minimizing the loads in the home in order to lower energy bills and maximize energy efficiency.
Artificial Lighting
Artificial lighting is provided by electricity, fixtures, and bulbs. Artificial lighting is a big contributor to high energy costs. It can contribute as much as 50 percent of the total energy costs of a home.
Lynn Clement of Focus on Energy once said, “If every American household replaces light bulbs in their five most frequently used fixtures with ENERGY STAR compact fluorescent bulbs, we could save more than $8 billion in annual energy costs and prevent greenhouse gases equal to the emissions of more than 10 million cars.”
Since lighting accounts for 20 to 25 percent of U.S. energy consumption, the move to more energy efficient lighting is very important.
Types of Lighting
There are three primary uses, or functions, for lighting in homes: task, ambient, and accent. Task lighting provides light to perform work. Ambient lighting may include light that is used for work but also includes lighting for safety and security. Any lighting used for contrast or ambiance is accent lighting. There are many different types of artificial lights available for residential uses.
Types of Artificial Lighting
Incandescent
Fluorescent
Compact fluorescent
High-intensity discharge
Halogen
Light Emitting diodes
Full Spectrum
Recessed Lights
Incandescent Bulbs
Incandescent bulbs, which are also referred to as A-type bulbs,.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

2. Introduction
India is facing significant growth in electricity demand and could
benefit greatly by using energy efficient lighting systems. The need
of the hour for the country is secured, affordable and
environmentally sustainable energy to meet the ambitious National
Programme of “Power to all by 2012”.
Lighting is the most visible form of electricity consumption and
lighting load in our country is very high about 17-18% of total load.
By increasing the efficiency of lighting system, there can be
significant energy saving and reduction in peak load. There is a
scope for reducing about 30 to 35 % of the morning and evening
peak demand.
3. Scheme for Promoting Energy Efficiency in India :
Bachat Lamp Yojana
The 'Bachat Lamp Yojana' aims at the large scale replacement of
incandescent bulbs in households by CFLs. It seeks to provide CFLs to
households at the price similar to that of incandescent bulbs and plans to
utilize the Clean Development Mechanism (CDM) of the Kyoto Protocol to
recover the cost differential between the market price of the CFLs and the
price at which they are sold to households.
The Bachat Lamp Yojana is designed as a public-private partnership
between the Government of India, private sector CFL suppliers and State
level Electricity Distribution Companies (DISCOMs). The CFL suppliers
would sell high quality CFLs to households at a price of Rs. 15 per CFL
within a designated project area in a DISCOM region of operation. The CFL
supplier will be chosen by the DISCOM through a due diligence process
from a list of CFL suppliers empanelled by BEE. Under the scheme, 40
watt, 60 Watt and 100 Watt incandescent lamps will be replaced with 9-11
Watt, 13-15 Watt and 20-23 Watt CFLs respectively.
4. Best Practices in Lighting Systems

9. Solar Lighting Systems
The Solar Lighting Systems are available in the basic categories which are
as follows:
(A) Solar lanterns (B) Solar street lighting systems (C) Solar home lighting
systems
The solar lanterns are portable units which can be easily moved to any
place where lighting is necessary. The lanterns are available with a 10 or 12
Wp photovoltaic module and a 7 W CFL. It can be used for 3 to 4 hours per
day after charging it for a day under normal insolation of 2-3 kWh/day.
The solar street lighting systems are available with a 70 Ah Battery. It has
an automatic dusk to dawn Controller, with at least 3 days of back up power
in case of low insolation regime.
The solar home lighting systems are available with basic configuration of
either 2 × 9 W CFLs or 2 × 11 W CFLs, with a 40 Ah Battery capable of
operating for three to four hours per day. A small DC Fan of 20 W capacity
can also be opted for.
10. Energy Conservation Measures
in Lighting Systems
• Use of LED lamps for indicating lamps will reduce the energy
consumption.
• Use of compact fluorescent lamps in place of incandescent
lamps, reduce the lighting energy by 70%.
• Use of mirror optic fluorescent lamps increases the lighting level
considerably.
• Use of HPSV lamps in place of MPSV lamps reduce the energy
consumption by 60%
• As the lighting level is inversely proportional to square of the
distance, optimizing the height of lamp will aid in reduction of
lighting energy.
11. Energy Conservation Measures
in Lighting Systems Contd…
• Use of electronic ballasts for discharge lamps, reduce energy
consumption by 20%
• Installation of intelligent lighting controller will help in controlling the
lighting energy.
• Use of photo sensor switch for street light controlling helps in conserving
the lighting energy.
• Installation of auto cut-off switch to put off lights during lunch
hours at the office buildings will reduce the lighting energy.
• At street lights, in many places, the reflectors inside the HPSV fitting are
damaged, it is suggested to replace the fittings with anodised aluminium
reflectors. This will improve the lighting level by 20-25%.
12. Why should people use CFLs?
• Switching from traditional light bulbs (called
incandescent ) to CFLs will help to use less electricity at
home and prevent greenhouse gas emissions that lead
to global climate change.
• Lighting accounts for close to 20 % of the average
home’s electric bill.
• CFLs, last upto 10 times longer, cost little up front
• Provide a quick return on investment.
13. Do CFLs contain mercury?
• CFLs contain a very small amount of mercury sealed within the
glass tubing - an average of 4 milligrams .By comparison the older
thermometers contain about 500 milligram of mercury – an amount
equal to mercury in 125 CFLs .
• Mercury is an essential part of CFLs; it allows the bulb to be
essential part of light source.
• No mercury is released when bulbs are intact or in use .Most
makers of light bulb have reduced mercury in their fluorescent
lighting products.
• Thanks to technology advances the average mercury content in
CFLs has dropped at least 20 % in the past year. Some
manufacturers have even made further reductions, dropping
mercury content to 1.4-2.5milligrams per light bulb.
14. What precaution should take when using CFLs
in home?
CFLs are made of glass and can break if dropped or
roughly handled. Be careful when removing the bulb
from packaging, installing it, or replacing it. Always screw
or unscrew the light bulb by its base (not the glass ), and
never forcefully twist the CFL into light socket .If a CFL
breaks in your home follow the clean up
recommendations given by Bureau of Energy Efficiency.
15. Key Product Features of CFLs
Low electrical consumption as compared to conventional
lighting products
About 80% energy saving over incandescent bulbs.
Long life up to 10,000 hours.
It can operate within 130-280 V range.
Low cost of maintenance.
High luminous efficiency.
Available in different colors to create desired ambience.
Lamps designed for power factor higher than 0.85.
Mercury content within the CFLs (Maximum Limit being
less than 5mg).
16. What is LED?
• LED is a light emitting semiconductor diode that emits
light in forward direction or in the direction it is pointed
towards.
• LEDs are most often used in the form of an indicator light
in electronic devices, traffic signal lights, musical
instruments and dashboards in cars and in houses, etc.
• The color of the light produced by LED depends on the
composition of the semiconductor material used out of
which producing a blue color light is the most difficult
process.
• The nature of the light emitted can be visible, infrared or
ultraviolet.
17. Lifespan of a LED light bulb
• Most modern LEDs are undergo superior design and manufacturing
process that gives them a lifespan of up-to 1,00,000 hours,
compared with 10,000 for a compact fluorescent and 1,000 for an
incandescent bulb.
• Lifespan of a LED bulb could come down due to the amount of heat
a LED produces. This directly depends on die temperature and
ambient temperature of the LED.
• Some LED light bulbs show sign of age after a couple of years of
use and may produce only 50% of the light output when compared
to what it used to produce when it was new. However new
technologies are in process to enhance its performance over its life
span.
18. Power consumption of LED light bulbs
• Most modern LED operate in a range of 2 to 4 volts and
consume anywhere between 350mA and 1500mA. The
power consumption varies from manufacturer to
manufacturer and also because of the purpose for which
the LED was designed.
• Another factor that affects power consumption of LEDs is
for the fact that LEDs can not be dimmed.
• Now a days using latest of the LED manufacturing
technology, manufacturers are able to produce LEDs
that are not only super bright but also consume less
power while producing light of higher intensity.
19. Benefits of using LED light bulbs over standard
light bulbs
• Power consumption of LED light bulb is only 10% of the standard
light bulb.
• LED light bulbs withstand great amount of vibration, shock and
temperature variations.
• LED light bulbs are 10-60 times more energy efficient than
incandescent light bulbs.
• Incandescent light bulbs produce light that flickers whereas LED
light bulbs produce flicker free light.
• LED bulbs can produce many rich and vibrant colors when
compared to incandescent light bulbs.
20. Key Product Features of LED light bulbs
• Low electrical consumption as compared to conventional lighting
products.
• Pollution free due to non-emission of infra red or ultraviolet
rays, mercury gases or other harmful rays.
• Do not have ballasts thus, no interference.
• Existing fixtures used since long are used making installation
of our lights easy.
• Operates on universal input range.
• Due to long shelf life, no maintenance is required.
• Lasts 5 to 10 times longer than other conventional lighting
products virtually eliminating the need for frequent
replacement.
• Reduces Carbon Footprints at large scale making it viable to
earn carbon credits.
• Suitable for all types of applications.
