Cold water evaporator with shell connected in series, copper pipe shared and single partition plate

Abstract

The invention discloses a cold water evaporator with shell connected in series, copper pipe shared and single partition plate. The evaporator comprises shells, a front end cover, a front separation plate, an partition plate, a rear end cover, a rear separation plate and a copper pipe, wherein the shells are a cylindrical cast iron shell; a plurality of sections of the shells are connected in an end-to-end mode in series and are sealed together; a refrigerant inlet is located at one third of a center line of a side wall of the shells, and a refrigerant outlet is located at the top of the shells; the refrigerant inlet and the refrigerant outlet are far away from each other in the axis direction of the shells; bolt holes are formed in the edge of a pipe shell and a bottom shell of the front end cover; the two ends of the partition plate are welded to the end parts of the two sections of the shells correspondingly; and a water cavity is formed between the rear end cover and the rear partition plate; and the copper pipe is arranged in the shells. According to the cold water evaporator with shell connected in series, copper pipe shared and single partition plate, refrigerant pipelines are arranged in each independent shell, so that space occupation is reduced; the water in the copper pipe can be fully utilized for heat exchange; and the heat exchange efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of central air-conditioning, in particular to a cold water evaporator with a shell connected in series with copper pipes sharing 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,...

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
