Embodiment Construction

[0015] The device for continuously producing supercooled liquid ice slurry provided by the invention includes a refrigeration system and a supercooled liquid circulation system.

[0016] The present invention will be described in further detail by taking two supercoolers as examples below.

[0017] Such as figure 1 As shown, the subcooled liquid circulation system includes a subcooler assembly, a subcooled liquid circulation processing assembly and an ice storage tank.

[0018] The structure of the subcooler assembly is as follows: the subcoolers 8a and 8b are connected in parallel, and each subcooler can work simultaneously or switchable. Temperature sensors 15a, 17a, 16a are respectively provided at the inlet and outlet of the supercooled liquid and the inlet of the refrigerant of the subcooler 8a, and temperature sensors 15a, 17a, 16a are respectively arranged at the inlet and outlet of the supercooled liquid of the supercooler 8b and the inlet of the refrigerant The temp...

Abstract

The invention discloses a supercooled liquid ice slurry continuous preparation device which comprises a refrigeration circulating system and a supercooled water liquid circulating system, wherein the supercooled liquid circulating system comprises a supercooler assembly, a supercooled liquid circulating assembly and an ice storage tank; the supercooler assembly is formed by connecting n supercoolers in parallel; and the refrigeration system comprises a compressor, a condenser, a liquid storage device, a dry filter, an evaporating pressure regulating valve, a master solenoid valve, n throttle control assemblies and n refrigerant flow reversing assemblies. When a certain supercooler is blocked by ice, the valve in the flow channel can be closed, and the refrigerant flow reversing assembly can be adjusted to melt the ice by hot gas produced by the refrigerant; and after the ice barrier is eliminated, the valve can be opened. In the process, the supercoolers in other flow channels still work normally, thereby realizing continuous preparation of ice slurry. The ice melting heat source of the supercoolers is the condensation heat of the refrigerant in the refrigeration system without consuming additional electric energy, thereby reducing the energy consumption of the device.

Description

technical field [0001] The invention relates to a dynamic ice-making system, in particular to a device for continuously producing supercooled liquid ice slurry. The supercooled liquid referred to in the invention refers to supercooled water and supercooled aqueous solution. Background technique [0002] Ice slurry technology is a research hotspot in ice storage technology in recent years. Compared with static ice storage, ice slurry storage technology can overcome the inherent defects of static ice storage. During the static ice storage process, as the thickness of the ice layer increases, the thermal resistance of the ice layer increases, which reduces the evaporation temperature of the refrigerant in the evaporator, thereby reducing the efficiency (COP value) of the refrigerator. During the cooling process of the static ice storage system, there are ice bridges and ice-melting dead angles in some corners of the container, which makes the cooling speed slow and uncontrolla...
