Nowadays, the sacks of sleeping possess the only function of heating up your occupants, because they are done basically of thermal insulating materials and they carry out the main function of maintaining the temperature interns of the sack of sleeping producing thermal comfort to your occupants in cold times of the year. In the summer or hot days of the year, the sack of sleeping becomes obsolete, because your main function leaves of being used, therefore it is wanted that the temperature interns of the sack reaches levels of thermal comfort.

The refrigerators of air existent possess main function of producing thermal comfort to the occupants of any atmosphere. However before that sensation of the comfort happens the whole atmosphere it should be refrigerated producing electric power waste.

With the intention of taking advantage of the functions of both mentioned objects, we grew the present model of usefulness that united the two objects in only one product taking advantage of like this the whole potential of refrigeration for thermal comfort and optimizing the use of the electric power.

The sack of sleeping with system of refrigeration is composed of a sack of sleeping single or couple done of insulating material with 2 zipper for you close it and in the close inferior part to the feet is an apparel of refrigeration of small load, being this apparel an air-conditioned.

The model couple can possess an air conditioning of larger potency illus. 4 (2), because the area to be refrigerated is larger compared to the single model, because the thermal load and embraced area should obey the proportion of this increase.
