Air cooling machine “DETA Cold”

Air chiller uses ambient air instead of the threat of CFCs.

 

 

Air refrigerating machine be much simpler in your device, install and operate. It works on the technology of the air cycle, as the refrigerant air is used. For operation of the system requires only electricity and air, which are renewable, readily available, completely safe and free resource.

Description of air refrigerating machine:

Air refrigerating machine be much simpler in your device, install and operate than vapor compression, the use of which requires a highly specialized and highly qualified staff. For the functioning of the system requires only electricity and air, which are renewable, readily available, completely safe and free resource.

If you compare the power consumption, the refrigeration coefficient (ratio of allocated heat to consumed electricity) of the air refrigerating machine is compared with the refrigeration coefficient of the vapor compression machine at temperatures below -60°C. Upon further lowering the temperature difference increases in favour of the air cooling cycle.

 


The basic principle of the technology of the air refrigeration machine:

In the refrigeration and climatic equipment DETAIL: working on technology air cycle, as the refrigerant air is used. The use of the cycle of compression and expansion of air in the expander-compressor unit (the air heats up during compression and cools down during expansion) allows you to accurately set the desired temperature level, down to low temperatures.

A key feature of the technology that the turboexpander is on the same shaft as the compressor. Produced during the expansion of air to the impeller of the expander power is transmitted through the common shaft of the working wheel of the compressor and disposed in technology. Through the use of a power turbine expander power consumption of the equipment is reduced by 30% compared to conventional systems.

 

Technology advantages:

– no freezing. Stable maintenance in the cell/room humidity index at the level of 0-2%. Almost zero humidity ensures the complete absence of the formation of ice, snow and frost on the shelves, the walls of the room to be cooled and directly on stored products. Therefore, the need for defrosting (regular defrosting and cleaning the ice) is eliminated;

– lack of freon. Use the safest, environmentally friendly and affordable refrigerant – air. Unlike other refrigerants, the air does not harm the ozone layer and does not affect global warming. The cost of its replacement and refueling are not available;

– no oils. Due to the lack of friction pairs oil completely absent, which minimizes the risk of ignition system reduces maintenance costs and extends equipment life;

security. The lack of contours and pressure vessels (machines operate with minimum pressure 1 bar) and using as the refrigerant solely of atmospheric air. There is no need to have its own qualified maintenance personnel;

– reliability and functionality. High reliability and stability of the refrigeration and air-conditioning equipment DETA due to its resistance to external temperatures from -50°C to +50°C. Additional benefits of the installationsrunning on air refrigeration cycle, are their small size, low noise, no vibration, ease of installation and maintenance.

 

The description of air refrigerating machines “DETA Cold”:

Air cooling machine “DETA Cold” is designed to solve the problems of industrial and commercial cooling, industrial freezing (including ultra fast), and storage at temperatures from -40°C to -90°C. the Specified temperature range is maintained when stored in a thermally insulated chamber and circulating air in a closed circuit.

Air cooling machine “DETA Cold” is controlled by an adaptive controller that ensures the maintenance of the specified modes of operation of the air refrigeration machine, depending on its scope. The controller interface allows to provide programming modes “DETA Cold”, remote monitoring and other parameters required by custom functions.

 

Application:

Air cooling machine can be used:

for the freezing and storage of food products, including fish, caviar, seafood, pork, beef, poultry meat, semi-finished products, fruit, berries, vegetables;

storage of biomaterials and medical products;

for hardening metal and other industrial processes.
