Refrigeration evaporator with multiple sections of outer shells and double separation plates

Abstract

A refrigeration evaporator with multiple sections of outer shells and double separation plates comprises the outer shells, a front end cover, a front separation plate, the separation plates, a rear end cover, a rear separation plate and a copper pipe, wherein the outer shells are cylindrical cast iron outer shells, and the multiple sections of the outer shells are in series connection end to end and sealed; each section of the outer shell serves as an outer shell of an evaporator of a refrigerating system; each section of the outer shell is provided with a refrigerant inlet, a refrigerant outlet, an exhaust port and an oil discharge outlet; a bottom shell of the front end cover is in a shape like an Arabic number eight; the separation plates are two flange plates and are welded to the outer shells on the left and on the right respectively; the rear end cover is formed by welding a cylindrical shell of an outer ring and a spherical surface bottom cover; and the copper pipe is in the outer shells. Water channels of evaporators of multiple refrigerating systems are shared, so space occupation is reduced, and operation under stable working conditions is guaranteed according to actual operation 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-segment shell and double 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 result in different cooling capacity. For example, during the peak cooling period in summer, full power is required for cooling, but in winter and other seasons with less cooling demand, full power is not required. At present, there are also frequency conversion technologies that can solve the problem of changes in cooling capacity within a certain range, but they are actually h...

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
