Description

Technical Field

[0001] The utility model belongs to the technical field of modular ice melting units for ensuring ice melting rate and hydraulic balance in regional cooling ice storage systems. Specifically, it provides an ice melting modular unit suitable for regional cooling ice storage systems. The utility model involves the overall design of an ice storage tank, an ice melting circulation pump, a plate heat exchanger, a control cabinet, and an adjustable assembled unit base. Background Art

[0002] Conventional external ice melting systems are generally concrete ice troughs or large steel troughs, and the plate heat exchangers and ice melting circulation pumps are designed in groups to correspond to the ice storage troughs. In order to ensure the hydraulic balance of the ice melting pipes and achieve a consistent ice melting rate, multiple groups of same-flow pipes are generally set up; however, due to construction conditions, it is often difficult to achieve resistance balance in the same-flow pipes, resulting in incomplete ice melting and "ice lumps".

[0003] At the same time, since the plate heat exchangers, ice melting circulation pumps and ice storage tanks are arranged in a dispersed manner, they occupy a large area of ​​civil construction, the pipeline layout in the machine room is complex, and the construction is difficult.

[0004] Therefore, it is urgent to solve the problems of difficult hydraulic balance of large-capacity ice troughs, incomplete ice melting and scattered equipment layout. Utility Model Content
