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 relates to a cold water heat exchanger with multiple shells and double spacing boards. The cold water heat exchanger comprises shells, a front end cover, a front partition, spacing boards, a back end cover, a back partition and copper tubes, wherein the shells are cylindrical cast iron shells, and multiple shells are connected end to end in series and are sealed; each shell is used as a shell of an evaporator of a refrigerating system; a refrigerant inlet, a refrigerant outlet, an exhaust hole and an oil outlet are respectively formed in each shell; a bottom shell of the front end cover is in an eight shape; the spacing boards 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 andthe back partition; and a circular groove is formed in the back partition. According to the cold water heat exchanger, waterways of evaporators of a plurality of refrigerating systems are shared, so that the occupied space is reduced, and the operation in stable working conditions is guaranteed at any time according to actual operating conditions.

Description

technical field [0001] The invention relates to the technical field of central air-conditioning, in particular to a cold water heat exchanger with multi-section shells 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, but it is powerless to de...
