Anti-freeze circulation air conditioning system for coldest place

The present invention relates to an anti-icing circulation air conditioning system for extreme cold regions, and more particularly, to a circulation air conditioning system that maximizes heating efficiency and reduces equipment load through moisture removal and preheating when outside air is introduced.

Most of the energy used in the modern world is from stored resources such as oil or natural gas as its energy source.

In the past, such energy sources could be produced inland or in areas with easy workability, but in recent years, it is required to expand the range of production areas to extreme cold areas where human survival or work was not easy in the past. .

In addition, with the development of shipbuilding technology, icebreakers that operate in icy seas in extreme cold areas where ships could not operate were developed, and various technologies that can operate normally even in extreme cold areas are required. have.

In response to these demands, hulls, structures, and air conditioners that can be operated in extreme cold areas have been developed, but in the case of air conditioners, there is a problem in that the heating efficiency is lowered in extreme cold areas.

Specifically, in the case of extreme cold areas, the temperature of the outside air supplied from the outside is about -52°C, but the air to be supplied to the inside is about 20°C. There was a problem that caused an overload to the equipment and caused the failure of the equipment.

If the temperature of the supplied air does not meet the required level due to a decrease in the heating efficiency and equipment failure, it not only leads to a decrease in workability or the internal living environment, but also excessively due to the severe environmental factors such as extreme cold. It can cause fatal results for internal workers, so the need for improvement is strongly emerging.
