Refrigeration evaporator with multiple outer shell sections and single space plates

Abstract

A refrigeration evaporator with multiple outer shell sections and single space plates comprises an outer shell, a front end cover, a front space plate, the space plates, a rear end cover, a rear spaceplate 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 bottom shell of the front end cover is shaped like the number '8'. The two ends of each space plate are welded to the ends of the corresponding outer shell sections correspondingly. The rear end cover is formed by welding acylindrical 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 waterchannel, 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 conditioning, in particular to a refrigeration evaporator with a multi-section shell 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 it is powerless to d...

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
