Multi-section shell copper pipe sharing cold water evaporator with double partition plates

Abstract

The invention provides a multi-section shell copper pipe sharing cold water evaporator with double partition plates. The multi-section shell copper pipe sharing cold water evaporator comprises a shell, a front end cover, a front partition plate, the partition plates, the rear end cover, a rear partition plate and a copper pipe. The shell is a cylindrical cast iron shell, multiple sections of the shell are connected together in series in an end-to-end manner and sealed, each section of the shell serves as a shell body of the evaporator of a refrigerating system, and each section of the shell isprovided with a refrigerant inlet, a refrigerant outlet, an exhausting opening and an oil drain opening. A bottom shell of the front end cover and the edge of a pipe shell are provided with bolt holes. The partition plates are two flange discs and are welded to the shell bodies on the left side and the right side correspondingly. A water cavity is formed between the rear end cover and the rear partition plate. The copper pipe is arranged in the shell. According to the evaporator, a water way of the evaporator of multiple refrigerating systems is shared, space occupation is reduced, and it isensured that the evaporator operates under the stable working condition according to the actual operation working condition.

Description

technical field [0001] The invention relates to the technical field of central air-conditioning, in particular to a cold water evaporator with multiple sections of shell copper tubes sharing double partition plates. 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...

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
