Ultralow-temperature combined type assembly refrigeration house refrigerating system

Abstract

The invention relates to the technical field of ultralow-temperature combined type assembly refrigeration houses, in particular to an ultralow-temperature combined type assembly refrigeration house refrigerating system. The ultralow-temperature combined type assembly refrigeration house refrigerating system comprises a closed space and refrigerating equipment. The refrigerating equipment comprises an outdoor unit, an evaporator and a draught fan. The outdoor unit is located on the outer side of the closed space. The evaporator is connected with the outdoor unit. The closed space comprises a bottom plate. A plurality of supporting strips are arranged on the upper surface of the bottom plate in parallel. The evaporator comprises a plurality of liquid distribution pipes. Every two adjacent supporting strips are arranged in a spaced manner. Each liquid distribution pipe corresponds to the position between every two adjacent supporting strips. A separation assembly is arranged between every two adjacent supporting strips. A plurality of air holes are formed in each separation assembly in the length direction of the corresponding supporting strip. The liquid distribution pipes are located below the separation assemblies, and a ventilation channel is defined by each separation assembly and the corresponding adjacent supporting strip. An air box is arranged at an end of each ventilation channel. An air outlet hole communicating with the corresponding ventilation channel is formed in each air box. The draught fan is installed on the air boxes. The ultralow-temperature combined type assembly refrigeration house refrigerating system has the effect that temperature distribution in the closed space is uniform.

Description

technical field [0001] The present application relates to the technical field of an ultra-low temperature combined assembled cold storage, in particular to a refrigeration system for an ultra-low temperature combined assembled cold storage. Background technique [0002] Food, medicine or vaccines often need to be stored at low temperature. Due to the large amount of storage in industrial production, it is necessary to build cold storage for storage. The temperature required varies according to the different items stored. Some items are stored in low-temperature cold storage, and some items Stored in ultra-low temperature cold storage, and items are stored in refrigerated cold storage. [0003] In the related art, the cold storage includes a closed space and refrigeration equipment. The refrigeration equipment includes a compressor, an evaporator and a condenser. The evaporator is arranged inside the closed space, and the evaporator is arranged outside the closed space, and t...
