Multi-section shell copper pipe water way single-spacing-plate refrigeration evaporator

Abstract

The invention discloses a multi-section shell copper pipe water way single-spacing-plate refrigeration evaporator. The multi-section shell copper pipe water way single-spacing-plate refrigeration evaporator comprises shells, a front end cover, a front separation plate, a spacing plate, a back end cover, a back separation plate and copper pipes; the shells are cylindrical cast iron shells; multiplesections of the shells are serially connected end to end and sealed; each section of the shell serves as a shell of an evaporator of a refrigeration system; each section of the shell serves as a shell of an evaporator of a refrigeration system; each section of the shell is provided with a refrigerant inlet, a refrigerant outlet, an exhaust port and an oil discharge port; a bottom shell of the front end cover is 8-shaped; the two ends of the spacing plate are respectively welded at the end parts of two sections of the shells; the back end cover is welded by a cylindrical shell on the outer ring and a spherical bottom cover; and the copper pipes are in the shells. Water ways of evaporators of multiple refrigeration systems are shared to reduce occupied space; and operation under stable working conditions is guaranteed according to actual operation working conditions at any time.

Description

technical field [0001] The invention relates to the technical field of central air-conditioning, in particular to a refrigeration evaporator with a multi-section shell copper tube waterway and a single partition plate. 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...

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
