Cascaded ice-storage air conditioning system and method utilizing same to supply cold air for air conditioner

Abstract

The invention discloses a cascaded ice-storage air conditioning system and a method utilizing same to supply cold air for an air conditioner. The cascaded ice-storage air conditioning system comprises a centrifugal cooling water system, a dual-mode unit system and an ice cold-storage system, wherein the centrifugal cooling water system comprises a centrifugal cooling water circuit and a centrifugal refrigerant circuit; the dual-mode unit system comprises a dual-mode cooling water circuit and a dual-mode refrigerant circuit; the ice cold-storage system comprises a refrigerant circuit; a first evaporator and a second plate-type heat exchanger form an independently connected circular cooling water circuit along with a frozen water pump, a water segregator, end equipment and a water collector respectively; the centrifugal cooling water system is connected with the dual-mode unit system by a first plate-type heat exchanger; the first plate-type heat exchanger is connected with the cooling water pump and the first evaporator so as to form an ice-making frozen water circuit; the first plate-type heat exchanger and a second cooling water pump and a second condenser form the ice-making frozen water circuit, and the end equipment is connected with the air conditioner that needs to be supplied with cold air. The cascaded ice cold-storage air conditioning system has high efficiency, can supply cold air reliably, can prepare and store ices effectively at low valley, and can save energy and charges.

AI Technical Summary

Benefits of technology

This patented technical solution described in this patents describes different types of ice-generative air conditioners (CAC) used for building applications such as renewable power generation facilities. These CAC have three modes: normal operation, offline use, and hybrid operating mode. They operate separately without interference from another type of facility. By combining these functions together they offer more efficient performance than traditional methods like multiple separate units installed on top of buildings. Additionally, their design allows for independent maintenance and replacement of backup supplies while minimizing costs. Overall, these technologies enhances both thermal management and security capabilities in new construction environments.

Problems solved by technology

This patented describes different ways how current systems use separate components like both refrigeration and ice making functions. These technical problem addressed by this patents include improving efficient utilization of space while maintaining safety during prolonged periods of nonuse without wasting valuable materials such as water or electricity.
