Double-partition-plate refrigerated heat exchanger with copper pipe waterway connected by shells in series

Abstract

The invention discloses a double-partition-plate refrigerated heat exchanger with a copper pipe waterway connected by shells in series. The refrigerated heat exchanger comprises the shells, a front end cover, a front separation plate, the partition plates, a rear end cover, a rear separation plate and a copper pipe, wherein the shells are cylindrical cast iron shells, and the plurality of sectionsof shells are connected end to end in series and are sealed; and refrigerant inlets are located at the positions, located at one third of the center lines of the side walls of the shells, refrigerantoutlets are located at the tops of the shells, the refrigerant inlets and the refrigerant outlets are far away from one another in the axis directions of the shells; a bottom shell of the front end cover is 8-shaped; the partition plates are two flange plates and are correspondingly welded with the shells on the left side and the right side of the corresponding partition plate; the rear end coveris formed by welding a cylindrical shell of an outer ring and a spherical bottom cover; and an annular groove is formed in the rear separation plate. According to the double-partition-plate refrigerated heat exchanger with the copper pipe waterway connected by the shells in series, an refrigerant pipeline is arranged in each independent shell, so that the space occupation is reduced; and water inthe copper pipe can be fully utilized for heat exchange, and heat exchange efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of central air-conditioning, in particular to a refrigeration heat exchanger with copper tubes connected in series to water channels with 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 certai...

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
