What is waiting for refrigerating technique in the XXI century

The ways of further development of civilization will determine the scale and forms of application of LTE in future. It is of much importance to appropriately and in due time evaluate the perspectives. This will allow to avoid deadlock ways of LTE development and to choose those directions of LTE that will he much demanding in future. The scale of use of LTE, as in the earlier time, will be primarily determined by the increase in production and consumption of foods.

The deficiency in energy sources will constantly increase hence, the compromises with respect to the use of energy' inefficient systems (methods) of refrigeration will be excluded.

The use of heat using refrigerating systems will he expanded, the use of natural cold will be increased, the use of secondary heat sources, unconventional energy sources, heat pump systems, combined systems of low- temperature power generation will be expanded. There will be no longer a neglecting attitude to «unusual» solutions of heat and cold supply problems that was determined by relatively favorable conditions of the XX century, especially in rich countries. The LTE itself will become the basis and the integral part of fundamentally new methods of energy production. The rote of LTE in the solution of global ecological problems will arise.

The application of LTE in protection of environment will increase. In connection with this the use of natural working substances (refrigerants): ammonia, hydrocarbons, carbon dioxide, water, air will predominate.

There will be a higher interest in new environmentally safe and energetically efficient principles of cold production (for example, metal hydrides — hydrogen).
