AI Technical Summary

Technical Problem

Existing ice storage cooling technology suffers from problems such as heat loss and ice blockage in pipes during ice making, leading to a reduction in equipment lifespan.

Method used

The system employs a direct expansion ice storage unit, which converts ambient air into hot air through a condenser composed of multiple copper tubes and an expansion valve. Low-temperature, low-pressure gaseous refrigerant evaporates and absorbs heat in the ice storage tubes. Combined with an ice crusher that grinds large ice blocks, a closed-loop cycle is formed, reducing damage to the water pump.

Benefits of technology

It improves ice storage efficiency, extends equipment life, achieves energy saving and stable cold load release, and has the advantages of energy saving, consumption reduction and operational reliability.

Abstract

The utility model discloses a direct-expansion ice storage all-in-one machine, and relates to the technical field of ice storage. The air conditioner comprises a machine shell, a dustproof filter plate is installed on one side of the machine shell, a condenser is fixedly connected to one side of the dustproof filter plate, the condenser is composed of multiple layers of coiled copper pipes, a drying bottle is fixedly connected to the copper pipe at one end of the condenser, and an expansion valve is fixedly connected to the drying bottle through the copper pipe. One end of the expansion valve is also connected with a copper pipe, the copper pipe is connected with the interior of the ice storage barrel shell in a penetrating mode, the top of the ice storage cavity is movably connected with a sealing cover, the multiple sets of copper pipes penetrate through the sealing cover, one end of each copper pipe is fixedly connected with a filter, the middle of each copper pipe is fixedly connected with an ice crusher, and the other end of each copper pipe is fixedly connected with a water pump. The ice-water mixture in the ice storage cavity is protected by the filter and the ice crusher, so that the damage to the water pump is reduced, the service life of equipment is prolonged, meanwhile, uniform ice water is ensured to be conveyed to the evaporator to stably release cold energy, and finally closed circulation is formed.
