Solar adsorbing type refrigerator

Abstract

The invention discloses a solar adsorbing type refrigerator which comprises an outer box body, wherein a plurality of small holes are arranged on the outer wall of the outer box body; an inner box body with an upper cover is sleeved in the outer box body; a water absorbing filler is filled in an interlayer arranged between the outer box body and the inner box body; a water filling port for filling water to the filler is arranged at the top of the filler; a liquid reservoir clung to the wall of the inner box body is arranged in the outer box body; the liquid reservoir is connected with an adsorbent bed which can be put outdoors through a circulating pipeline; an adsorbent is coated on the adsorbent bed; and an electric heating plate is arranged at the bottom of the adsorbent bed. The invention utilizes the mechanism of evaporative type refrigeration and adsorption refrigeration, realizes all-day refrigeration of the refrigerator in the day and at night by utilizing solar, and meantime has easy acquisition of materials and simple structure. The invention has the most important characteristics that the solar adsorbing type refrigerator does not need electric power in the using process, only uses a little electric power in overcast and rainy weather, can not discharge materials dangerous to the environment, truly achieves the purpose of less electric power consumption and environmental friendliness, and can be widely applied to various refrigeration conditions.

Description

technical field [0001] The invention relates to a refrigerator, in particular to a solar adsorption refrigerator capable of refrigerated storage of food or other perishable items with low power consumption. Background technique [0002] A refrigerator is a household appliance commonly used in people's lives, and is also commonly used in medical treatment and experiments. At present, the common refrigerators on the market are compression refrigerators, and its working principle is that the mechanical energy provided by the motor works on the refrigeration system through the compressor. The refrigeration system uses the low boiling point refrigerant to absorb the heat of vaporization when it evaporates to achieve the purpose of refrigeration. However, this type of refrigerator is refrigerated by consuming electric energy. In order to achieve the purpose of refrigerating items and cooling them below 0° C., a large amount of electric energy is required. But in fact, the temper...
