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

Abstract

The invention discloses a multi-section shell shell-tube double-spacing-plate cold water heat exchanger. The multi-section shell shell-tube double-spacing-plate cold water heat exchanger comprises shells, a front end cover, a front separation plate, spacing plates, a back end cover, a back separation plate and copper pipes; the shells are cylindrical cast iron shells; multiple sections of the shells are serially connected end to end and sealed; each section of the shell serves as a shell of an evaporator of a refrigeration system; each section of the shell is provided with a refrigerant inlet,a refrigerant outlet, an exhaust port and an oil discharge port; bolt holes are formed in the edges of a bottom shell of the front end cover and a tube shell; the spacing plates are two flange plates, and are respectively welded with the shells on the left and right sides; a water cavity is formed between the back end cover and the back separation plate; and the back separation plate is providedwith a ring groove. Water ways of evaporators of multiple refrigeration systems are shared, so that occupied space is reduced; and operation under stable working conditions is guaranteed according toactual operation working conditions at any time.

Description

technical field [0001] The invention relates to the technical field of central air conditioning, in particular to a multi-section shell-and-tube type double partition plate cold water heat exchanger. 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, but it is powerless to...
