Air source simultaneous cold-warm type cold storage and drying system

Abstract

The invention provides an air source simultaneous cold-warm type cold storage and drying system. According to the air source simultaneous cold-warm type cold storage and drying system, one device is used for conducting cold storage and drying at the same time, and the equipment cost and the running cost are saved. The air source simultaneous cold-warm type cold storage and drying system comprisesa compressor, an oil separator, a gas-liquid separator, a liquid storage device, a four-way valve, three heat exchangers, an expansion valve and three draught fans. An outlet of the compressor is connected with an inlet of the oil separator. A gas-state working medium outlet of the oil separator is connected with one end of a heat exchange structure of a drying room heat exchanger, and the other end of the heat exchange structure of the drying room heat exchanger is externally connected to a first through connection head of the four-way valve through a pipeline. The four-way valve further comprises a second through connection head, a third through connection head and a fourth through connection head. The second through connection head is connected with one end of a heat exchange structureof an outdoor heat exchanger through a pipeline, and the other end of the heat exchange structure of the outdoor heat exchanger is connected with one port of the liquid storage device. The other portof the liquid storage device is connected with one port of the expansion valve, and the other end of the expansion valve is connected with one end of a heat exchange structure of a cold storage warehouse heat exchanger through a pipeline.

Description

technical field [0001] The invention relates to the technical field of refrigeration and drying systems, in particular to an air source simultaneous cooling and heating type refrigeration and drying system. Background technique [0002] Some agricultural products on the market need to be refrigerated and some need to be dried during storage, but most of the equipment on the market can only provide refrigeration or drying functions. When refrigerating, the heat is dissipated outside, and when drying, the heat source is Outdoors; when a certain place needs refrigeration and drying at the same time, two sets of equipment are needed, and the investment cost is high and the operation cost is high. Contents of the invention [0003] In view of the above problems, the present invention provides an air source cooling and heating type refrigerating and drying system, which uses a set of equipment to simultaneously refrigerate and dry, saving equipment costs and operating costs. ...
