Multi-shell copper pipe waterway double-spacing-plate refrigeration heat exchanger

Abstract

The multi-shell copper pipe waterway double-spacing-plate refrigeration heat exchanger comprises shells, a front end cover, a front partition plate, spacing plates, a rear end cover, a rear partitionplate and a copper pipe; the shells are cylindrical cast iron shells, the multiple sections of shells are connected end to end in series and sealed; each shell serves as a shell of an evaporator of arefrigeration system and is provided with a refrigerant inlet, a refrigerant outlet, a gas outlet and an oil outlet; a bottom shell of the front end cover is in the shape like the Arabic number eight;the spacing plates are flange plates and welded to the shells on the left side and the right side correspondingly; the rear end cover is formed by welding an outer circle cylindrical shell and a spherical bottom cover; and the rear partition plate is provided with an annular groove. According to the multi-shell copper pipe waterway double-spacing-plate refrigeration heat exchanger, the evaporators of the multiple refrigeration systems share the same waterway, the occupied space is decreased, and the effect that operation is conducted under the stable working condition is ensured according tothe actual operation working condition at any time.

Description

technical field [0001] The invention relates to the technical field of central air-conditioning, in particular to a refrigeration heat exchanger with multi-segment shell copper pipe waterways and 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, b...

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
