Optimize your air_circulation_and_minimize_your_air_conditionerAshok Sethuraman
Air conditioner usage makes everyone one of us, accountable to Local & Global Warming. First the AC user, as electricity consumer, and next the AC OEM who had given previously, yester-year-starred AC but now poorly rated, and last but not the least, the Govt, which needs to promote mandatorily, the Energy conservation in AC, AC Run hour & KWH monitoring, Star rated AC promotion and sales tax reduction in Star rated AC & other energy saving & monitoring gadgets.
The optimization of Air circulation inside the premises is that to ensure adequate but mild Air changes inside the premises, and not air blast by the old ceiling fans. This enables you to minimize the Air conditioner settings from 22* C to 27 * C first thus comforting you mildly with Air conditioning + air circulation around you. Automatically this will reduce the running AC hours, less AC KWH units consumed per day now.
Ceiling fan is mostly driven by the single induction motor with an efficiency of 30%.
The BLDC motor is popular now a days for a high efficiency, compactness and controllability.
An AC drive is a device used to control the speed of an electrical motor. The speed is controlled by changing the frequency of the electrical supply to the motor.
Design topology of a remote-controlled bi-directional rotation of an A.C. fan...IJECEIAES
The use of remote control for alternating current fans in homes/offices is one of the applications of electronics that enhances human comfort. It should therefore not be seen as luxury, rather, it should be taken as a basic requirement of life. In this study, the bi-directional rotation and speed control of ac fan was achieved using ardiuno microcontroller and tuned capacitors circuits. The use of the new state-of- the art technique in this work is significant because it helped in over-coming the drawbacks associated with the use of inductive, resistive and phase angle controlled regulators. The significance of this study will be of great benefit to physically challenged and aged persons who need to have their comforts in their various places of sitting. The designed topology of the work was executed and achieved. Reliability test carried out on the finished work showed better efficiency.

Memorandum Of Association Constitution of Company.pptseri bangash
www.seribangash.com
A Memorandum of Association (MOA) is a legal document that outlines the fundamental principles and objectives upon which a company operates. It serves as the company's charter or constitution and defines the scope of its activities. Here's a detailed note on the MOA:
Contents of Memorandum of Association:
Name Clause: This clause states the name of the company, which should end with words like "Limited" or "Ltd." for a public limited company and "Private Limited" or "Pvt. Ltd." for a private limited company.
https://seribangash.com/article-of-association-is-legal-doc-of-company/
Registered Office Clause: It specifies the location where the company's registered office is situated. This office is where all official communications and notices are sent.
Objective Clause: This clause delineates the main objectives for which the company is formed. It's important to define these objectives clearly, as the company cannot undertake activities beyond those mentioned in this clause.
www.seribangash.com
Liability Clause: It outlines the extent of liability of the company's members. In the case of companies limited by shares, the liability of members is limited to the amount unpaid on their shares. For companies limited by guarantee, members' liability is limited to the amount they undertake to contribute if the company is wound up.
https://seribangash.com/promotors-is-person-conceived-formation-company/
Capital Clause: This clause specifies the authorized capital of the company, i.e., the maximum amount of share capital the company is authorized to issue. It also mentions the division of this capital into shares and their respective nominal value.
Association Clause: It simply states that the subscribers wish to form a company and agree to become members of it, in accordance with the terms of the MOA.
Importance of Memorandum of Association:
Legal Requirement: The MOA is a legal requirement for the formation of a company. It must be filed with the Registrar of Companies during the incorporation process.
Constitutional Document: It serves as the company's constitutional document, defining its scope, powers, and limitations.
Protection of Members: It protects the interests of the company's members by clearly defining the objectives and limiting their liability.
External Communication: It provides clarity to external parties, such as investors, creditors, and regulatory authorities, regarding the company's objectives and powers.
https://seribangash.com/difference-public-and-private-company-law/
Binding Authority: The company and its members are bound by the provisions of the MOA. Any action taken beyond its scope may be considered ultra vires (beyond the powers) of the company and therefore void.
Amendment of MOA:
While the MOA lays down the company's fundamental principles, it is not entirely immutable. It can be amended, but only under specific circumstances and in compliance with legal procedures. Amendments typically require shareholder
Implicitly or explicitly all competing businesses employ a strategy to select a mix
of marketing resources. Formulating such competitive strategies fundamentally
involves recognizing relationships between elements of the marketing mix (e.g.,
price and product quality), as well as assessing competitive and market conditions
(i.e., industry structure in the language of economics).

2. Inverter Air-conditioning
• Rising Sales trend of Inverter Airconditioners has observed in
current year / season due to fulfill the consumer needs i.e.
– Energy savings is one of the most important factors.
– Status quo
• In current year, “Gree” became the most renowned & popular
brand in Inverter Air conditioners.
• 15 ~ 20% sales share of Inverter Airconditioners in the total sale
of Gree AC’S at yet as claimed by the Gree officials.
• The inverter air conditioning is the latest technology in the
HVAC field that is becoming more popular due to its energy
savings and environmental friendly approach. Providing
comfort to the users is another big advantage of this kind of
system.
• So what exactly is this inverter-based air conditioning and how it
is different from the existing technology? Let’s examine that:
5. Inverter Technology : Basic
Traditionally, the compressor that is used in an air
conditioning system is an ON or OFF type in which it
either works at the maximum capacity or none at all. It
ON when the room thermostat calls for cooling and
OFF when the desired temperature has been achieved.
This cycle is repeated with the change of load in the
room.
Inverter A/C’s compressor works with variable speed.
In that way compressor only works only at desired
power/speed, which means does not have to run on its
maximum capacity all the time.
Speed of the compressor can be controlled by
controlling the input frequency of the compressor.
Variable frequency can be obtained by a INVERTER.
6. Inverter Technology : Basic
Inverter is an electronic device which converts DC to
AC.
The advancement in Solid-State Power Electronics has
enabled the inverter technology to thrive by the use of
microcontroller and IGBT modules to drive the
compressor DC or AC motor.
7. Inverter Technology : Basic
An Air Conditioner bearing inverter tag uses a variable frequency
drive to control the speed of the motor and thus the compressor. It
consumes at least 30% less (it can go to 50% or more) electricity
depending on various factors like the outside temperature ,purpose for
which the AC is used, Hence it uses less amount of electricity.
Inverter is a device which supplies variable frequency of power
supply on
equipments.
Thanks to this function , motor revolution speed can be controlled and
it
9. Benefits: Soft Start
Soft Start
• Soft starter is
making electrical
installation work
much simpler.
• At startup, Inverter
raises frequency
smoothly.
• “Eliminating the
starting current
spike”.
11. Inverter: Long Term Benefits
Potential Electricity Savings :
Non inverter Technology Products to Inverter
Technology
Let’s say a non inverter AC having a rating of 1.5 KW takes 7.0
Amps and an inverter AC having a rating of 2.6 KW (operates
between 0.9~3.0 KW) draws 2.8 Amps.
For a smooth 8 hours operation per day the non inverter AC
consumes 10 units, while for the same operation an inverter AC
consumes 4 units. If we fix the unit price to an average of Rs.
6/unit, a non-inverter AC contributes Rs. 1,800/- per month,
while for the same period an Inverter AC has a running cost of
Rs.720/- per month giving you flat savings of Rs. 1,080/- per
month.
If an Inverter AC costs Rs.100,000/- and for the same rating and
cooling a non-inverter AC costs Rs. 65,000/- then payback period for
Inverter ACs is merely 3 years.
13. Energy Efficient Refrigerant
• R32 is 10% more energy efficient than conventional
refrigerant at the same volume.
•Potential of Refrigeration capacity :1.6 times of
R410A
•Lower pressure loss, when capacity is same, leads to
thinner piping diameter.
•GWP of R32 is 675, which is 1/3 of that of
conventional refrigerants such as R410A and R22.
Also, it can reduce charge volume by about 30%
when optimized. All together it can reduce GWP
by 75% in total.
14. Conclusion
• The potential of reduction of electricity consumption
by air conditioner is high. Inverter and R32 are the
technologies to increase energy efficiency of
equipment.
• Inverter technology can increase energy efficiency by
30% compared to non-inverter.
• R32 is 10% more energy efficient than conventional
refrigerant at the same volume. GWP (Global Warming
Potential) of R32 is 675, which is 1/3 of conventional
ones.
• When inverter & R32 refrigerant are applied to high-
end model, potential increase of energy efficiency will
be significant.
