Multi-section shell and copper pipe shared single-spacing-board refrigeration evaporator

Abstract

The invention discloses a multi-section shell and copper pipe shared single-spacing-board refrigeration evaporator. The multi-section shell and copper pipe shared single-spacing-board refrigeration evaporator comprises shells, a front end cover, a front partition plate, a spacing board, a rear end cover, a rear partition plate and copper pipes. The shells are cylindrical cast iron shells, and themultiple sections of the shells are connected end to end to be connected together in series and be sealed. Each section of the shell serves as an evaporator shell of a refrigeration system and is further provided with a refrigerating fluid inlet, a refrigerating fluid outlet, an air exhaust outlet and an oil drain outlet. A bottom shell of the front end cover and the tube-shell edge are provided with bolt holes. The two ends of the spacing board are welded to the ends of the two sections of the shells separately. The rear end cover is formed by welding a cylindrical shell of an outer ring andspherical bottom cover. The copper pipes are arranged inside the corresponding shells. According to the multi-section shell and copper pipe shared single-spacing-board refrigeration evaporator, waterroutes of the evaporators of the multiple refrigeration systems are shared, space occupancy is reduced, and the effect that the multi-section shell and copper pipe shared single-spacing-board refrigeration evaporator operates under the stable working condition can be guaranteed at any moment according to the actual operation conditions.

Description

technical field [0001] The invention relates to the technical field of central air-conditioning, in particular to a refrigeration evaporator with a single partition plate shared by multiple shell copper tubes. 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 po...

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
