Abstract

The invention discloses an ice storage refrigeration system and a refrigeration method thereof, which relate to the technical field of refrigeration air conditioners. The ice storage refrigeration system comprises a refrigeration unit, a tail end device, an ice making unit, a heat exchange device and an ice storage device, wherein an evaporator of the ice making unit, the ice storage device and acold fluid flow passage in the heat exchange device are connected by a pipeline loop; a hot fluid flow passage in the heat exchange device is connected with the loop of the tail end device via a pipeline; a loop between the condenser of the ice making unit and the evaporator of the refrigeration unit is provided with a pipeline; and the cooling water of the condenser of the ice making unit is supplied after being precooled to 2-20 DEG C by the refrigeration unit. According to the ice storage refrigeration system, the problems that the traditional refrigeration unit can not work under the ice making working condition and a refrigeration unit of double working conditions has big compression ratio, high cost and the like and is complex to control under the ice making working condition are solved, the cost of the refrigeration system can be lowered, and ice making efficiency and operation stability are improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to the technical field of refrigeration and air conditioning. Background technique [0002] Conventional refrigeration systems are generally composed of refrigeration equipment, cold source devices, terminal devices, auxiliary equipment, connecting pipelines, and control systems. The most widely used refrigeration equipment is a vapor compression refrigeration unit, which consists of an evaporator, a compressor, a condenser, and a throttling device connected through copper pipes to form a closed circuit, and the circuit is filled with refrigerant. When the refrigeration unit is working, the refrigerant circulates in the evaporator, compressor, condenser, and throttling device to perform four processes of evaporation, compression, condensation, and throttling, and transfers heat from the evaporator to the condenser. [0003] In a typical refrigeration system, the refrigerating...
