Copper pipe water channel double-space-plate refrigeration evaporator with multiple outer shell sections

Abstract

A copper pipe water channel double-space-plate refrigeration evaporator with multiple outer shell sections comprises an outer shell, a front end cover, a front space plate, space plates, a rear end cover, a rear space plate and a copper pipe. The outer shell is a cylindrical cast iron outer shell. The multiple outer shell sections are connected end to end in series and sealed. Each outer shell section is used as an outer shell body of an evaporator body of a refrigeration system and provided with a refrigerant inlet, a refrigerant outlet, an exhaust port and an oil discharging outlet. A bottomshell of the front end cover is shaped like the number '8'. Two flange plates are used as the space plates, and the space plates are welded to the outer shell sections located on the left side and the right side correspondingly. The rear end cover is formed by welding a cylindrical shell on the outer ring with a spherical-surface-shaped bottom cover. The copper pipe is arranged in the outer shell. The evaporator bodies of multiple refrigeration systems share a water channel, the occupied space is reduced, and stable operation under the working conditions is ensured at any time according to the actual operation working conditions.

Description

technical field [0001] The invention relates to the technical field of central air conditioners, in particular to a multi-section shell copper tube water channel double partition plate refrigeration evaporator. Background technique [0002] Both the evaporator and the condenser in the refrigeration system are a specific form of heat exchangers. In the central air-conditioning industry, the evaporator has a variety of forms, including shell-and-tube, plate and other forms. Shell and tube type is generally suitable for air-cooled units for preparing cold water. In most regions of the country, different seasonal differences lead to different cooling capacity. For example, during the peak cooling period in summer, full power is required for cooling, but in winter and other seasons with less cooling demand, full power is not required. At present, there are also frequency conversion technologies that can solve the problem of cooling capacity changes within a certain range, but th...

AI Technical Summary

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
