Embodiment Construction

[0035] see figure 1 , the ice storage refrigeration device includes a casing 1 with waterproof, moisture-proof and thermal insulation properties, and the casing 1 constitutes a closed body with a cavity inside. The closed body is generally a cuboid or cylinder, and it can also be Other regular or irregular shapes are adopted; a heat exchange coil 2 is provided in the cavity, and the heat exchange coil 2 is used for heat exchange between the liquid in the tube (generally water) and the refrigerant in the cavity outside the tube to store ice And cooling is carried out by the flow of liquid in the tube. The heat exchange coil 2 can be fixedly installed by a support frame 3 arranged in the cavity, and the support frame 3 can be positioned on the inner surface of the shell; the inlet and outlet ends of the heat exchange coil are respectively connected to the chilled water on the shell 1 On the inlet 4 and the chilled water outlet 5, generally, the chilled water inlet 4 is located ...

Abstract

The invention provides an ice-storage refrigeration device and an ice-storage refrigeration system, belongs to the air conditioning refrigeration technology and mainly solves the technical problem that the existing energy-storage air conditioning system has low energy efficiency and the like. The ice-storage refrigeration device comprises shells; a sealing body with a chamber inside consists of the shells; and the chamber is internally provided with a heat-exchanging pipe coil. The ice-storage refrigeration system consists of an ice-storage system and an ice-melting and cold-releasing system. The invention applies a principle of icing inside pipes, melting ices and ice-storing by spraying and cooling outside the pipe, needs no secondary heat-exchanging devices, greatly reduces the initial investment, has high system energy efficiency, low running expense, quick coldness storage, quick coldness taking speed, good heat exchange effect, reduces the energy consumption of the refrigeration mainframe by about 6% and can be widely applied to the air conditioning refrigeration systems.

Description

technical field [0001] The invention relates to air-conditioning refrigeration technology, and relates to an ice-storage refrigeration device in an air-conditioning system and an ice-storage refrigeration system using the device. Background technique [0002] At present, the ice storage systems commonly used in air-conditioning equipment at home and abroad are roughly divided into series and parallel systems according to the relative positions of the refrigeration unit and the ice storage device in the system. The two ice storage systems are realized by setting the secondary heat exchange device, which leads to an increase in the cooling temperature of the air conditioning system, which not only increases the energy loss caused by heat exchange, but also increases the initial investment of the system; secondly Compared with the conventional air conditioning system (the outlet water temperature of the evaporator is 7°C), the outlet water temperature of the brine side in the s...
