Abstract

The invention provides a display cabinet with a dehumidification effect and a control method. The display cabinet comprises a cabinet body, a first evaporator, a second evaporator and a liquid supplypipe, and airflow of an air return opening sequentially passes through the second evaporator and the first evaporator and then enters the cabinet body. According to the display cabinet with the dehumidification effect and the control method, the two evaporators are arranged, a temperature ladder is formed, return air is cooled step by step, the uniformity of the temperature of the return air is guaranteed, meanwhile, the evaporator located at the lower side preferentially conducts condensation dehumidification on the return air, therefore frosting of the evaporator located at the upper side isavoided, the heat exchange efficiency of the first evaporator is greatly improved, so that the refrigeration cycle is prolonged, the energy consumption is reduced, the return air is fully and uniformly cooled, the stability of the temperature in the display cabinet is improved, the storage period of food is prolonged to a certain extent, and the storage effect is enhanced.

Description

technical field [0001] The invention relates to the technical field of article display devices, in particular to a display cabinet with a dehumidification effect and a control method. Background technique [0002] The vertical open refrigerated display cabinet is favored by customers for its elegant appearance, refrigerated and fresh-keeping, all-round display of goods, and convenience for customers to choose. It has been widely used in supermarkets and shopping malls in recent years. The existing refrigerated display The cabinet is generally an integral evaporator, such as figure 1 As shown, there is a temperature difference between the inlet and outlet, but the evaporator as a whole is in a low temperature state, and the temperature difference between the return air and the return air is relatively large, and uneven heat transfer is prone to occur during heat exchange. When the return air with high temperature and high humidity When the gas exchanges heat with the evapora...
