Problems solved by technology

[0002] Existing supercooled water ice storage air conditioners usually use ethylene glycol solution as the secondary refrigerant. First, the refrigerant is used as the primary refrigerant to cool down the ethylene glycol, and then ethylene glycol is used as the secondary refrigerant to cool the room. Glycol system, complex pipeline structure settings
And the load of the air conditioner must be able to reach the load of the air conditioner in the hottest period, and the required load is relatively large

Embodiment 1

[0071] The refrigerating unit includes an ice storage device 110, a cooling device, an ice making system, an ice melting system and a direct supply system. During the night valley power period, the ice making system is used to make ice. During the daytime peak power consumption period, the ice slurry made at night is directly melted, and the ice melting system is used to melt ice for cooling, which can effectively reduce the peak power consumption of the air conditioner during the day. load, save air-conditioning operating costs, reduce the installed capacity of air-conditioning hosts and corresponding transformers, power supply and distribution, reduce air-conditioning loads during peak hours of the power grid, effectively use night valley power, save energy and reduce emissions, and save air-conditioning operating costs.

[0072] Correspondingly, if the ice-melting system cannot supply enough cooling capacity during the period of about one month when the temperature is the hi...

The ice melting system includes a first water pump 122 , a second heat exchanger 131 and an ice slurry generator 200 .

[0133] That is to say, the ice-making system and the ice-melting system together form a circulation lo...

Embodiment 3

[0138] This embodiment provides a refrigeration unit. This embodiment is an improvement made on the basis of the technical solution in Example 1. The technical solution described in Example 1 is also applicable to this embodiment. The technical solution already disclosed in Example 1 No need to repeat the description, the difference between this embodiment and embodiment 1 lies in the ice making system, the ice melting system, the first cooling system and the second cooling system, and each system uses a water pump respectively.

[0139] Figure 8 It is a schematic structural diagram of the third process flow of the refrigeration unit provided in the embodiment of the present application. see Figure 8 , wherein the ice making system includes an ice storage device 110 , a second water pump 310 , a first heat exchanger 124 , and an ice slurry generator 200 which are sequentially arranged and communicated in a cycle. The ice-melting system includes an ice storage device 110 , ...
