About Absorption Chiller

An absorption chiller is a refrigeration machine, in which, in contrast to the compression refrigeration machine compaction influenced by temperature of the refrigerant solution. This is also known as a thermal compressor. The refrigerant is absorbed into a solvent circuit at low temperature in a second material and desorbed at higher temperatures. In the process, the temperature dependence of the physical solubility of two materials is used. Prerequisite for the process is that the two substances are mutually soluble in the temperature interval used in any ratio.
The absorption refrigeration cycle is considered the oldest known industrial process refrigeration, and originally was a request for freezing the main reason why in 1755 to deal with the development of heat pumps. In the first experiments of William Cullen (born April 15, † February 5, 1790), a physician and chemist, water was frozen with the aid of a vacuum. A continuously operating whole process was not developed.

Materials Innovations for Industry and Society

New materials are the engine for new production processes and products. In addition, new materials make a significant contribution to cost reduction in production. After all, the share of material costs is the cost of production in the manufacturing industry, around 50 percent. Savings through the efficient use of resources can lead to considerable competitive advantage.

Worker village

Today worker village is a must for big companies. Especially if you are mine company kind, you must create non-permanent buildings.

Conditions where your workers eat or sleep is directly associated to your work quality. But if you are a miner company in example you must think that you may move if you can’t find anything where you dig.

Prefabricated Dormitories

Prefabricated Dormitories are too important for lots of countries. Today one of the humanity’s biggest problem is illiteracy. In Africa there are 10 million children waiting for prefabricated dormitories. It’s so important because dormitory means hot meal and a safe place to sleep for school children in Africa.

It’s not possible to build school and dormitory to every little city. It’s some easy to give lesson for children in a single floor place. But it’s very hard to send them back their home everyday.
