Abstract

The invention relates to an air-conditioning technique, in particular to a dynamic ice-crystal storage and chilled water storage mixed system and a control method thereof. The system comprises a dual-condition water chilling unit (1), a dynamic ice-crystal ice making unit (2), a third heat exchanger (3), a cold storage tank (4), a first heat exchanger (5), a second heat exchanger (6) and an air-conditioning terminal (7). According to the control method, by switching a plurality of valves and water pumps, various conditions in a dynamic ice-crystal cold storage mode and a chilled water storage mode of the system are respectively realized. The advantages of two cold storage systems are sufficiently taken, the operating efficiency of the system is improved, and operating cost is reduced.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a hybrid system of dynamic ice crystal cold storage and water cold storage and a control method thereof. Background technique [0002] The dynamic ice crystal cold storage air conditioning system has the advantages of high ice production efficiency of the dual-working condition chiller, and its cold storage device has the advantages of small size and fast cooling speed, and its application projects are increasing day by day. However, the dual-working condition chiller of the water storage air-conditioning system has higher efficiency when storing cold, and the system is stable and reliable, but the cold storage device is large in size and its application is limited. Contents of the invention [0003] The technical problem solved by the present invention is to provide a hybrid system and its control method for sharing cold storage tanks, so that the system has the adva...
