Problems solved by technology
However, the arrangement of multiple refrigeration systems will lead to the problem of space utilization. Generally, the condenser can be installed outdoors, but as an evaporator, it must be installed indoors, and the space for the evaporator is limited. Multiple refrigeration systems must be considered. The installation space of the evaporator of the system

A shell-connected shell pipe type dual-spacing-board refrigeration heat exchanger comprises shells, a front end cover, a front spacing board, a spacing board, a rear end cover, a rear spacing board and a copper pipe. Each shell is a cylindrical cast iron shell, and multiple segments of shells are connected end to end in series and are sealed. Each segment of shell serves as a shell of an evaporator of a refrigeration system. The copper pipe carries out pipe shrinkage process treatment at the inserted connection tail end. Bolt holes are formed in the edges of a bottom shell and a pipe shell ofthe front end cover. The spacing board comprises two flange plates, and the two flange plates are welded to the shells on the left side and the right side correspondingly. The rear end cover is formedby welding a cylindrical shell on the outer ring and a bottom cover in a spherical surface shape. A ring groove is formed in the rear spacing board. According to the shell-connected shell pipe type dual-spacing-board refrigeration heat exchanger, the occupied space is small; and the copper pipe is welded after pipe shrinkage, relative sealing can be kept, and leakage is not prone to happening.
Description
technical field [0001] The invention relates to the technical field of central air-conditioning, in particular to a shell-and-tube type double partition plate refrigeration heat exchanger connected by shells. Background technique [0002] Both the evaporator and condenser in the refrigeration system are a specific form of heat exchanger. In the central air-conditioning industry, the evaporator has a variety of forms, including shell-and-tube, plate and other forms. The shell-and-tube type is generally suitable for air-cooled units that prepare cold water. In most regions of the country, different seasonal differences lead to different cooling capacity. For example, during the peak cooling time in summer, full power is required for cooling, but in winter and other seasons when cooling demand is low, full power is not required. At present, there is also frequency conversion technology that can solve the problem of cooling capacity changes within a certain range, but it is pow...
