Multi-stage temperature-controlling and humidity-adjusting cooling system

Abstract

The present invention relates to the technical field of cooling machines and particularly relates to a multi-stage temperature-controlling and humidity-adjusting cooling system. The multi-stage temperature-controlling and humidity-adjusting cooling system at least comprises three cooling systems of a first humidity-adjusting and temperature-controlling system, a second cooling system and a third cooling system; the first humidity-adjusting and temperature-controlling system comprises a first compressor, a first condenser and a hot coil connected by pipelines; the second cooling system comprises a second compressor, a second condenser, a throttling valve and a second evaporator successively connected by pipelines; the second evaporator is connected with the second compressor through pipelines to form a refrigeration circuit; and the third cooling system is the same as the second cooling system. The first humidity-adjusting and temperature-controlling system is used to conduct temperature controlling and adjusting; the second cooling system and third cooling system conduct combined refrigeration; and according to the refrigeration needs, the second cooling system and third cooling system are enabled or disenabled, so that the second cooling system and third cooling system are used a supplement to the first humidity-adjusting and temperature-controlling system.

Description

technical field [0001] The invention relates to the technical field of coolers, in particular to a cooling system with multi-stage temperature control and humidity regulation. Background technique [0002] When storing grain in the grain industry, the average grain temperature below 15°C is called low-temperature storage, and the average grain temperature between 15°C-20°C is called quasi-low temperature storage. The low-temperature storage of grain is recognized as a green, environmentally friendly, safe, and fresh-keeping method. With the improvement of people's living standards, the requirements for food safety and green pollution-free are getting higher and higher. Grain coolers have the advantages of ensuring bulk grain cooling, keeping fresh, reducing the use of pesticides, etc., and are used more and more. [0003] In order to meet the cooling capacity, the existing grain coolers generally use multiple compressors for refrigeration. During the application process, t...
