Two-level temperature-controlling humidity-adjusting cooling system

Abstract

The invention relates to the technical field of cooling machines, in particular to a two-level temperature-controlling humidity-adjusting cooling system. The two-level temperature-controlling humidity-adjusting cooling system comprises a first humidity-adjusting temperature-controlling system and a second cooling system; the first humidity-adjusting temperature-controlling system comprises a firstcompressor, and a first evaporator is connected with the first compressor through a fourth pipeline; and the first compressor is connected with a hot coil pipe through a second pipeline. As for different needs of cooling and dehumidification, the ratio of refrigerant passing through a first pipeline and the second pipeline is adjusted, when dehumidification is not needed, all the refrigerant enters a first condenser through the first pipeline, and when dehumidification is needed, the refrigerant can partially or wholly enter the hot coil pipe through a second guiding pipe for dehumidification. When the cooling capacity needs to be increased, the second cooling system is started for cooling and dehumidification, dehumidification is conducted through self thermal cycle, additionally arranging of dehumidification devices is not needed, energy is saved, materials are reduced, and dehumidification is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of coolers, in particular to a cooling system with two-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, the...

Problems solved by technology

[0004] Aiming at the above-mentioned problems that the existing grain cold dryers are turned on and off, cannot effectively cooperate with refrigeration, cause energy waste and loss of equipment, and have poor cooling effects. At the same time, they do not have the function of dehumidification. The wet cooling system, through the joint refrigeration of multiple compressor units, turns on the compressor units for cooling according to the cooling needs, and uses its own heat exchanger to heat and dehumidify, improve the comprehensive utilization of energy, and the equipment structure is simple and easy to control
