Embodiment Construction

[0014] specific implementation

[0015] Such as figure 1 , 2 , 3 shows: a portable solar vacuum refrigeration box, including a box body 1, two vacuum chambers 3 wrapped in the box body 1, a vacuum pump 8 for exhausting the vacuum chamber 3, and an intermittent power supply for the solenoid valve 7 and the vacuum pump 8 The temperature controller 9 is a solar panel 2 that provides electric energy for the solenoid valve 7 and the vacuum pump 8; it is characterized in that, the two long sides of the box 1 are equipped with solar panels 2, and the solar panels 2 pass through the hinge 2 -1 is hinged with the box body 1, and can be flipped and unfolded. Two manual button switches 10 and a temperature controller 9 are installed on the surface of the box body 1; the vacuum chamber 3 is a circular cylinder, and the bottom of the cylinder is placed The frame 5 and the net frame 5 below are used for water storage. The two vacuum chambers 3 are symmetrically distributed and equipped wi...

Abstract

The invention relates to a portable solar vacuum refrigeration box, in particular to freshness preservation during food movement. The portable solar vacuum refrigeration box is characterized in that two vacuum chambers are wrapped in a box body, a vacuum pump chamber is arranged between the box body and the vacuum chambers, solar panels which can be folded are distributed on the periphery of the box body, the solar panels supply power to an electromagnetic valve and a vacuum pump to exhaust the vacuum chambers to decrease the internal pressure of the vacuum chambers, and a refrigeration effect is produced if moisture exists in the vacuum chambers. The vacuum chambers are evaporators. Since open circulation is adopted and no complex system for compressive refrigeration exists, the portable solar vacuum refrigeration box has the advantages of simple structure, light weight and high refrigeration efficiency.

Description

technical field [0001] The invention relates to a portable solar vacuum refrigeration box, in particular to the preservation of food during the moving process. Background technique [0002] Compression refrigeration requires an evaporator, and the condenser system is relatively complex and relatively heavy. Contents of the invention [0003] The invention relates to a portable solar vacuum refrigeration box, which wraps two vacuum chambers in the box body, a vacuum pump room is arranged between the box body and the vacuum chamber, and foldable solar panels and solar battery panels are distributed around the box body. The board supplies power to the solenoid valve and the vacuum pump to exhaust the vacuum chamber, so that the pressure in the vacuum chamber drops, and if there is moisture in the vacuum chamber, it will produce a cooling effect. The vacuum chamber is the evaporator, which has simple structure, light weight and high refrigeration efficiency because it adopts ...
