Multi-shell copper pipe waterway single-spacing-plate water-cooled evaporator

Abstract

A multi-shell copper pipe waterway single-spacing-plate water-cooled evaporator comprises shells, a front end cover, a front partition plate, a spacing plate, a rear end cover, a rear partition plateand 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 a refrigeration 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 two ends of the spacing plate are welded to the ends of two sections of shells correspondingly; a water cavity is formed between the rear end cover and the rear partition plate; and the copper pipe isarranged in the shells. According to the multi-shell copper pipe waterway single-spacing-plate water-cooled evaporator, 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 to the actual operation working condition at any time.

Description

technical field [0001] The invention relates to the technical field of central air conditioners, in particular to a multi-section shell copper pipe water channel single partition plate cold water evaporator. Background technique [0002] Both the evaporator and the condenser in the refrigeration system are a specific form of heat exchangers. In the central air-conditioning industry, the evaporator has a variety of forms, including shell-and-tube, plate and other forms. Shell and tube type is generally suitable for air-cooled units for preparing cold water. In most regions of the country, different seasonal differences lead to 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 cooling capacity changes within a certain range, but they ...

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
