Double-temperature display cabinet and control method thereof

Abstract

The invention belongs to the technical field of storage devices and discloses a double-temperature display cabinet. The double-temperature display cabinet comprises a cabinet, layer plates and a heatpump device; an article storage area and an air duct located on the outer side of the article storage area are arranged in the cabinet; the article storage area comprises a first temperature storage area and a second temperature storage area; the air duct comprises an air inlet communicated with the outside; a first ventilation opening communicated with the air duct is formed in the side wall of the first temperature storage area; the layer plates are arranged in the second temperature storage area and used for supporting articles; the heat pump device comprises a compressor, first condensers,a throttling element, an evaporator and an evaporator fan, wherein the compressor, the first condenser, the throttling element and the evaporator form a circulation loop; the evaporator and the evaporator fan are arranged in the air duct and can refrigerate the first temperature storage area; the first condensers are buried in the layer plates and can heat the second temperature storage area; andtherefore, a double-temperature storage function can be achieved through one set of heat pump device, energy consumption can be effectively reduced; and the first condensers are buried in the layer plates, space can be saved, and the structure of the double-temperature display cabinet is compact.

Description

Technical field [0001] The present invention relates to the technical field of storage devices, and more particularly to a two-temperature display cabinet and a control method thereof. Background technique [0002] In supermarkets, shopping malls, food and other occasions, it is usually displayed or exhibited by display cabinets, such as fresh food or ingredients. [0003] A open display cabinet is provided in the related art, including an open storage bin, a refrigeration device is provided inside the display cabinet, and the air conditioner is generated by the refrigeration device and the air is blown to the storage bin. Refrigerated the items in the storage trainer. In order to maintain a stable temperature in the storage trainer, there is a stable curtain at the open space, and the heat exchange inside and outside the display cabinet is separated. However, the display cabinet provided in the relevant technologies, its working mode is single, typically only the items within th...

Problems solved by technology

However, the display cabinets provided in the related art have a single working mode, and usually can only keep the items in the storage compartment under the same temperature condition. When different items need to be stored in different temperature environments, the display cabinets provided in the related art Cabinets cannot meet the needs

[0004] In this regard, another open display cabinet with different temperature environments is provided in the related art. A hot air source and a cold air source are provided in the display cabinet. The items in the display cabinet are heated or refrigerated, so that the interior of the display cabinet can be kept at different temperatures, which can meet the needs of various items for different temperatures. However, due to the use of two relatively independent heating systems and cooling systems , while the heating system and refrigeration system occupy too much space, it also has the disadvantages of high energy consumption and excessive heat generation
