The 2011 Import and Export Market for Machinery for Making Hot Drinks or for Cooking or Heating Foods in Africa

The 2011 Import and Export Market for Machinery for Making Hot Drinks or for Cooking or Heating Foods in Africa Review


See more picture


On the demand side, exporters and strategic planners approaching the market in Africa face a number of questions. Which countries are supplying machinery for making hot drinks or for cooking or heating foods to Africa? What is the dollar value of these imports? How much do the imports of machinery for making hot drinks or for cooking or heating foods vary from one country to another in Africa? Do exporters serving the market in Africa have similar market shares across the importing countries? On the supply side, Africa also sells to the international market of machinery for making hot drinks or for cooking or heating foods. Which countries in Africa supply the most exports of machinery for making hot drinks or for cooking or heating foods? Which countries are buying their exports? What is the value of these exports and which countries are the largest buyers?

This report was created for strategic planners, international marketing executives and import/export managers who are concerned with the market for machinery for making hot drinks or for cooking or heating foods in Africa. With the globalization of this market, managers can no longer be contented with a local view. Nor can managers be contented with out-of-date statistics that appear several years after the fact. I have developed a methodology, based on macroeconomic and trade models, to estimate the market for machinery for making hot drinks or for cooking or heating foods for those countries serving Africa via exports or supplying from Africa via imports. We do so for the current year based on a variety of key historical indicators and econometric models.

In what follows, Chapter 2 begins by summarizing where Africa fits into the world market for imported and exported machinery for making hot drinks or for cooking or heating foods. The total level of imports and exports on a worldwide basis, and those for Africa in particular, is based on a model which aggregates across over 150 key country markets and projects these to the current year. From there, each country represents a percent of the world market. This market is served from a number of competitive countries of origin. Based on both demand- and supply-side dynamics, market shares by country of origin are then calculated across each country market destination. These shares lead to a volume of import and export values for each country and are aggregated to regional and world totals. In doing so, we are able to obtain maximum likelihood estimates of both the value of each market and the shares that countries in Africa are likely to receive this year. From these figures, rankings are calculated to allow managers to prioritize markets within Africa. In this way, all the figures provided in this report are forecasts that can be combined with internal information for strategic planning purposes.

On the demand side, exporters and strategic planners focusing on machinery for making hot drinks or for cooking or heating foods in Canada face a number of questions. Which countries are supplying machinery for making hot drinks or for cooking or heating foods to Canada? How important is Canada compared to others in terms of the entire global and regional market? How much do the imports of machinery for making hot drinks or for cooking or heating foods vary from one country of origin to another in Canada? On the supply side, Canada also exports machinery for making hot drinks or for cooking or heating foods. Which countries receive the most exports from Canada? How are these exports concentrated across buyers? What is the value of these exports and which countries are the largest buyers?

Cooling efficiency in contained applications using intelligent controls.(Report): An article from: ASHRAE Transactions

Cooling efficiency in contained applications using intelligent controls.(Report): An article from: ASHRAE Transactions Review

This digital document is an article from ASHRAE Transactions, published by American Society of Heating, Refrigerating, and Air-Conditioning Engineers, Inc. on July 1, 2010. The length of the article is 3018 words. The page length shown above is based on a typical 300-word page. The article is delivered in HTML format and is available immediately after purchase. You can view it with any web browser.

From the author: Two of the biggest challenges in data centers today are the increasing heat density of the IT equipment and the energy required to operate and cool that equipment. In order to operate efficiently while dealing with these increasing leads, many best practices must be incorporated. Best practices such as arranging racks in hot-aisle/cold-aisle configuration, covering all unused rack space with blanking panels, and sealing all cable cutouts in the raised floor must be done to accomplish effective and efficient cooling. This paper will go beyond these basic requirements to look at the effect of using aisle containment in conjunction with the necessary monitoring and control of the cooling system to provide a more efficient cooling system. This is accomplished by controlling both the supply air temperature and airflow to align the cooling system with the rack temperature and airflow requirements. Comparisons between several scenarios will be made.

Dehumidification of outdoor air in datacom environments for air-side economizer operation.(Report): An article from: ASHRAE Transactions

Dehumidification of outdoor air in datacom environments for air-side economizer operation.(Report): An article from: ASHRAE Transactions Review


See more picture


This digital document is an article from ASHRAE Transactions, published by American Society of Heating, Refrigerating, and Air-Conditioning Engineers, Inc. on January 1, 2009. The length of the article is 7468 words. The page length shown above is based on a typical 300-word page. The article is delivered in HTML format and is available immediately after purchase. You can view it with any web browser.

From the author: The decision to activate an air-side economizer is typically based on a comparison of the outdoor and return air enthalpy of the two airstreams; the stream utilized is the one with the lowest enthalpy. For data centers that comply with the high supply air conditions recommended in ASHRAE's Thermal Guidelines for Data Processing Environments (ASHRAE 2004a); however, conditioning the return air typically only requires sensible cooling. If the outdoor air with low enthalpy but high dew point is utilized, a dehumidification process is needed in addition to a sensible cooling process. This dehumidification process (desiccant or otherwise) will have a COP different from sensible cooling, which will affect the range of psychrometric conditions suitable for economizer use. The purpose of this paper is to look at the efficiency of the dehumidification process (mechanical refrigeration vs. desiccant) needed to utilize this high dew point outdoor air to allow for air-side economizer operation.
