High-efficiency ice storage system method

Abstract

The invention discloses a high-efficiency ice storage system method. The method specifically comprises the steps of 1, a conventional air-conditioning refrigeration and ice-making unit combined cold working condition; 2, a conventional air-conditioning refrigeration and ice-making unit ice storage working condition; 3, an ice-making unit independent ice storage working condition; 4, an ice storagedevice independent cold working condition, and 5, a conventional air conditioner and ice storage device combined cold working condition. The invention relates to the technical field of air conditioner ice storage. With the high-efficiency ice storage system, an auxiliary device is added to help an ice-making coil to be more prone to ice making and de-icing, chilled water is utilized to transfer the heat to a refrigerant or an ethylene glycol solution through a plate exchanger to realize de-icing, and the cold capacity released by the ice-making coil during de-icing is directly absorbed by thechilled water for air-conditioning refrigeration, so that the refrigerating cold capacity is not wasted; extra heat source for deicing does not need to be additionally added during de-icing, an ice maker works in an ice-making state all the time, and the conversion is not needed; and the ice-making amount is large, the efficiency is high, the cold storage capacity per unit capacity of an ice storage device is large, and the cold capacity released during de-icing can be stored as needed.

Description

technical field [0001] The invention relates to the technical field of air-conditioning ice storage, in particular to a high-efficiency ice storage system method. Background technique [0002] The air-conditioning ice storage technology is to use electric refrigerators to cool the cold storage medium during the low power consumption period at night when the power load is very low, so that the cold storage medium is frozen, and the cooling capacity is stored by using the sensible heat and latent heat characteristics of the cold storage medium. During the day when the power load is high, that is, the peak period of power consumption, the cold storage medium is melted to release the stored cold energy to meet the needs of building air conditioning or production processes. The ice storage system generally consists of refrigeration, cold storage and power supply. The refrigeration and cold storage system is composed of four major parts: refrigeration equipment, cold storage devic...
