Efficient refrigerating system based on cold accumulation and supercooling

Abstract

The invention relates to an efficient refrigerating system based on cold accumulation and supercooling. The efficient refrigerating system comprises a compressor, a condenser, a first throttling device, a cold accumulation module, a three-way valve, a second throttling device, an evaporator and an electromagnetic valve. The compressor is provided with an exhaust port, a first suction port and a second suction port. The exhaust port of the compressor is sequentially connected with the condenser, the first throttling device, the cold accumulation module and an inlet of the three-way valve through a connecting pipe. A first outlet of the three-way valve is connected with the second suction port of the compressor through a connecting pipe. A second outlet of the three-way valve is sequentially connected with the second throttling device, the evaporator and the first suction port of the compressor through a connecting pipe. An inlet of the first throttling device communicates with the second outlet of the three-way valve through a connecting pipe provided with the electromagnetic valve. Compared with the prior art, the cold accumulation module serves as the fifth major component of the refrigerating system, the system always works with the economical refrigerating amount, the cold accumulation technology and the improvement of the supercooling degree of the refrigerating system are combined, and the capability and efficiency of the refrigerating system are improved.

Description

technical field [0001] The invention relates to a vapor compression refrigeration system, in particular to a high-efficiency refrigeration system based on cold storage and supercooling. Background technique [0002] For example, each car has its own economic speed, too fast or too slow will consume more fuel, and the air conditioner also has the most efficient "economic cooling capacity". Taking refrigeration and air conditioning as an example, the cooling capacity can only obtain the optimal cooling efficiency within a certain range. If more or less cooling capacity is provided, the cooling efficiency will drop rapidly. If the refrigeration system can always work efficiently at the "economic cooling capacity", and at the same time adapt to load changes through cold storage technology, that is, store cold during the cold supply valley and release cold during the cold supply peak, the energy consumption of the system can be effectively reduced throughout the day.

Problems solved by technology

Although this type of cold storage technology is conducive to shifting peaks and valleys of electricity and increasing the power load rate of the grid, it does not help the refrigeration system itself; moreover, the traditional cold storage device takes up a lot of space and consumes a lot of energy during the cold storage process.
