Description

Technical Field

[0001] The utility model relates to the technical field of cold bridge prevention, in particular to a cold bridge prevention structure of an outdoor cold storage structure. Background Art

[0002] Cold storage technology can transfer the low temperature of the fluid in one link of the system to the coolant through heat exchange, and then the coolant can store the absorbed cold energy through temperature changes. When the terminal system needs to cool down, the coolant can release the cold energy through circulation. In this way, the equipment utilization rate is improved and the construction and operation costs are reduced. This kind of cold storage technology often uses outdoor cold storage structures for cold storage operations;

[0003] Existing outdoor cold storage structures generally use cold storage tanks, but when the existing cold storage tanks are performing cold storage operations, cold bridges often occur. Cold bridges refer to the situation where when the building's external enclosure conducts heat with the outside world, the heat transfer coefficient of some parts of the enclosure structure is significantly greater than that of other parts, causing heat to be concentrated and quickly transferred from these parts, thereby increasing the building's air conditioning, heating load and energy consumption;

[0004] Cold bridges have a destructive effect on the outer wall of the cold storage tank. It will increase the cold consumption of the cold storage tank and waste the energy of cold storage. At the same time, there will be condensation water on the high-temperature side. The long-term effect of condensation water will cause damage to the outer wall structure of the cold storage tank and shorten the service life of the cold storage tank. Utility Model Content
