Problems solved by technology

[0003] The suction temperature of the compressor in the refrigeration system has a great influence on the reliability of the compressor. When the suction superheat is too high, it may cause the compressor discharge temperature and discharge pressure to exceed the specified value; when the suction superheat is low Even when the temperature is lower than 0°C, the inlet of the compressor contains liquid refrigerant, which will cause liquid shock in the compressor and affect the life of the compressor

Abstract

The invention discloses a refrigerating system, a control method and an air conditioner. The refrigerating system comprises a compressor, a condenser, a throttling valve and an evaporator which are sequentially connected end to end. The electric power storage assembly is arranged on the air outlet side of the condenser, and the semiconductor refrigeration assembly is arranged between the compressor and the evaporator. The electricity storage assembly is arranged on the air outlet side of the condenser and used for recycling heat released by the condenser and converting the heat into electricity, and the greenhouse effect caused by the heat is avoided; in addition, the electric energy source of the semiconductor refrigeration assembly is heat released by the condenser, and therefore waste heat utilization of condensation heat is further achieved; the semiconductor refrigeration assembly can adjust the air suction superheat degree value of the compressor, the situation that when the air suction superheat degree is too high, the exhaust temperature and exhaust pressure of the compressor exceed specified values is avoided, and meanwhile the situation that when the air suction superheat degree is low or even lower than 0 DEG C, an inlet of the compressor contains liquid refrigerants, and the liquid impact phenomenon of the compressor occurs is avoided. And the service life of the compressor is influenced.

Description

Technical field [0001] The present invention relates to the field of refrigeration techniques, and more particularly to a refrigeration system, a control method, and an air conditioner. Background technique [0002] The refrigeration system is typically composed of four main components of the evaporator, a compressor, a condenser, and an expansion valve, sequentially connected by a line to a closed cycle system. The liquid refrigerant absorbs heat of the cooling space or the heat of the cooled object in the evaporator, gasifier into a low temperature and low pressure gas refrigerant, is inhaled by the compressor, and is discharged into a condenser, in the condenser, in the condenser The medium-to-cooling medium (air) is exothermic, condensing is a high pressure liquid refrigerant, and the expanded valve fertilizer is a low temperature low pressure liquid refrigerant, and then enters the evaporator in the evaporator to heat the gasification to achieve the purpose of circulating re...
