Abstract
The utility model discloses a high-and-low temperature humid heat test box, which belongs to the field of refrigerating detection equipment and mainly structurally comprises an evaporator, a condenser, a refrigerating compressor, a circulating fan, a heat insulation layer, a capillary tube, a copper tube, a liquid outlet tube, a liquid return tube and the like. The evaporator is connected to the capillary tube through the copper tube and then connected to the condenser, the condenser is connected with the refrigerating compressor through the copper tube, and the evaporator is connected with the refrigerating compressor through the liquid return tube. The capillary tube in the original structure is arranged in the liquid return tube, harmful residual cold energy in the liquid return tube and inner cold energy in the capillary tube are in heat exchange, and the harmful residual cold energy is converted into beneficial refrigerating capacity so as to increase liquid return temperature of a refrigerating compressor, thereby further condensing inflow liquid of the evaporator, reducing temperature of the inflow liquid of the evaporator, increasing evaporation efficiency of the evaporator, and reducing refrigerating energy consumption and increasing refrigerating effect.
Description
Technical field
The utility model relates to a kind of temperature control experimental facilities, the warm and humid heat test case of particularly a kind of height.
