Air curtain type showcase

Abstract

The invention provides an air curtain type showcase, relates to the technical field of showcases, and solves the technical problems that in the prior art, the exchange proportion of a cold air curtainof a showcase and external energy is large, and the cooling capacity is wasted. The air curtain type showcase comprises a showcase body with an air curtain opening, wherein the showcase body comprises: a first air duct, wherein airflow blown by the first air duct can form a first air curtain at the air curtain opening or near the air curtain opening; a second air duct, wherein airflow blown by the second air duct can be close to the first air curtain on the inner side of the first air curtain to form a second air curtain, so that the first air curtain is located between the external environment and the second air curtain; an evaporator which is arranged in the second air duct. The evaporator is only arranged in the second air duct, the temperature of the first air curtain and the temperature of the second air curtain can be different, the first air curtain with the temperature higher than that of the second air curtain is used for preventing the second air curtain with the temperaturelower than that of the second air curtain from making contact with the outside, and therefore the energy exchange proportion of the cold air curtain and the outside is reduced, and waste of cooling capacity is reduced.

Description

technical field [0001] The invention relates to the technical field of display cabinets, in particular to an air curtain display cabinet. Background technique [0002] The display cabinet is a kind of refrigeration equipment commonly used in shopping malls, supermarkets, bars, KTV and other places to refrigerate alcohol, beverages, fruits and vegetables, cosmetics, etc. Common display cabinets are closed and open air curtain. For the open air curtain display cabinet, the energy exchange between the cold air curtain of the display cabinet and the outside world occupies a considerable proportion, which wastes cooling capacity; generally, the air curtain display cabinet will be equipped with partitions in the display cabinet for display Goods, and partitions will affect the circulation of cold air and affect the refrigeration efficiency of the display cabinets, especially when the partitions of the display cabinets are full of goods, the circulation of the cold air will not be...
