Description
Technical field
The present invention relates to technical field of central air, more particularly to shell is connected the partition plate cold water heat exchange of copper pipe water route separate room
Device.
Background technology
Evaporator and condenser in refrigeration system are all a kind of concrete forms of heat exchanger, in central air-conditioning industry,
The form of evaporator is more varied, including the diversified forms such as shell-and-tube, board-like.Shell-and-tube applies in general to prepare cold water
Air-cooled unit.In national most of region, different calendar variations causes refrigerating capacity different, such as the refrigeration peak of summer
When need to put into high gear to freeze, but full-amount inrush is then not required in refrigeration demand less season in the winter time etc..Mesh
It is preceding also to there is converter technique to solve the problems, such as that refrigerating capacity changes in certain scope, but change for excessive refrigerating capacity
It is in fact helpless.The cold that separate unit handpiece Water Chilling Units are capable of providing is limited, is run together by more handpiece Water Chilling Units to improve
Refrigerating capacity, respective refrigeration system still independent operating are not interfere with each other, and stop several systems when refrigeration capacity requirement is reduced
Cooling system.But the arrangement of multiple refrigeration systems can cause the problem of space availability ratio, condenser general still solution installed outdoors
Certainly, but as evaporator interior is necessarily mounted at, and the space for accommodating evaporator is limited, it is necessary to consider that multiple refrigeration systems
The installation space problem of the evaporator of system.
