This document discusses the Variable Refrigerant Flow (VRF) air conditioning system. It provides economical and comfortable air conditioning for a wide range of applications from homes to businesses. The compact VRF system is suitable for apartments, homes, shops, and offices. It allows for individual temperature control and easy switching to standby mode. Special tools are required for R410A refrigerant piping work.
A bagging line in a production plant is closely tied to the associated production and distribution processes, including the upstream and downstream logistics. This may have an impact on the availability of the entire production plant and must therefore be taken into account in evaluating and designing the line.
2016 marks the 10th anniversary of the launch of Copeland Scroll Digital compressors for refrigeration applications. What a journey it has been since its official introduction in 2006! It may be a surprise to some, but since launching in 2006, digital scroll sales have seen a mean annual growth rate of more than 30% in Europe – and this over a period when there has been parallel attention to alternative forms of modulation, such as inverter driven compressors. In the last few years Scroll Digital has found its own sweet spot in modulating refrigeration applications and is now widely accepted in food service and food retail applications. The whole idea of developing this technology was to keep things simple for customers while providing the main benefits of modulating capacity: precise temperature control and energy efficiency. Based on the sales figures, Emerson is proud to say that customer expectations have been met.
Variable refrigerant flow (VRF) systems, which were introduced in Japan in 1982, have become popular in many countries, yet they relatively unknown in the United States. VRF systems can condition multiple zones in a building, each of which may have different heating and cooling needs. Using sophisticated control technologies, VRF systems can modulate amount of refrigerant sent to each zone independently and in tune with diverse and changing space conditioning loads, providing substantial energy savings.

Variable refrigerant flow (VRF) is an air-condition system configuration where there is one outdoor condensing unit and multiple indoor units. The term variable refrigerant flow refers to the ability of the system to control the amount of refrigerant flowing to the multiple evaporators (indoor units), enabling the use of many evaporators of differing capacities and configurations connected to a single condensing unit. The arrangement provides an individualized comfort control, and simultaneous heating and cooling in different zones.

GONKA, established as a limited company in 1986 in Ostim, Ankara, has become one of the leading firms in Heating - Cooling - Air Conditioning - Ventilating Installation, with the high performance and disciplined working mentality of Halil GONCU (Mechanical engineer, BS MS ITU, 1975) and Salih KADAYIFCIOGLU (Mechanical Engineer, BS GU, 1982) within more than 23 years for both manufacturing and contracting.
GONKA Company, has been continuing its activities, in its factory located in Sincan Organized Industrial Area, since 1996. GONKA manufactures its products related to Heating - Cooling - Air Conditioning - Ventilating Installation in its factory in an area of 10.000 m2 and equipped with the latest technology.
GONKA, which is continuing its activities through its technical and managerial staff in its modern Directorate General Building in Cetin Emec Boulevard, Ankara which it has moved in 2002, has been replaced "GONKA Air Conditioning Installation Construction and Trade Joint-Stock Company" by transforming into "joint-stock company" in 2003.
GONKA enforces its activity in Turkey By serving through its network consisted of Istanbul and Ankara Region Offices and maintenance-repair services firms. In regions other than these, GONKA offers contact and service through local offices and central maintenance-repair crews.
GONKA; has KnowHow, especially about the field of "Clean Room" technology, which requires sterility in operating theatres and air conditioning-ventilating systems of environments such as operas, theatres, auditorium buildings, television studios which require silence.
GONKA has created "model company" profile in air conditioning sector through both manufacturing or supply of devices and its disciplined approach in mechanical operations by succeeding a lot of projects within last 23 years. GONKA, which has focused on internto 32 countries and succeeded many projects in Middle-East, Asia and Africa countries by its powerful foreign trade departmentational projects in last 15 years, gave representations
In this project, experimentation is done on Vapour Compression Refrigeration System
[VCRS] as the COP is high for this system and it is the present trend of the HVAC in the
domestic industry. This study presents investigation of best suited refrigerant and
insulation combination for gas pipeline and liquid pipeline of a split air conditioning
system. Analysis are performed for R22-Chlorodiflouromethane, a HydroChloroFlouro
Carbon refrigerant, which has been using in the present world that cause both global
warming and ozone layer depletion and R410a, mixture of di-flouromethane and
pentaflouroethane, a Hydroflouro carbon refrigerant, which is future of HVAC which
reduces the effect of ozone layer depletion [ODP] and Global Warming Potential
[GWP].For these two refrigerants, we had found out the best insulation suitable as
insulation also affects the COP of air conditioner, which has been observed from the
literature. Minimizing the temperature of refrigerant in suction line helps condensing unit
work more effectively intern the system performance increases. This reduces the overall
power required for working of air conditioner, thereby reducing the maintenance cost of
system. Also, it helps the manufacturer to provide best type of insulation for the system at
reduced cost thereby reducing overall cost of VCRS.To perform the experimental
comparison, 16 tests were carried out for 5 times with each refrigerant Insulation
combination. From analysis it is observed that, COPA for NRF+AF gives highest value
for R22 and R410awhen compared to various insulation materials. Power required for
VCRS is greater while using R410a than R22. So In this work the main energy parameters
such as COP and work required for compressor are analysed and discussed.
White paper - Ingeteam's new-generation power converters for 6-8 MW wind tur...Ingeteam Wind Energy
The wind sector is globally focusing its efforts on reducing the Levelized Cost of Energy (LCoE) of the technology in order to prove itself as a profitable option in the energy mix regarding electrical generation. In response to this market outlook, OEMs are working hard to develop wind turbines with a power range exceeding 6 MW, which potentially enables the reduction of the LCoE of the wind farm.
The upgrade of the power converter to power rates above 6 MW requires a detailed knowledge of DFIG features, especially the main design constraints of this topology, like the peak currents during FRT events, or the mechanical behavior of the whole converter inside the wind turbine. The design process followed by Ingeteam covers all these aspects and the new generation products ensure the reliable operation of the system.

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
