Description

Handpiece Water Chilling Units dry evaporator

Technical field

The present invention relates to technical field of central air more particularly to handpiece Water Chilling Units dry evaporators.

Background technology

Central air-conditioning provides cold water using the form of centralized cooling for whole building, is then changed again by fan coil etc. Cold is sent to each room by hot component step by step.Although building structure has generally reserved certain space to central air conditioning Group, but the form of the evaporator of the handpiece Water Chilling Units of central air-conditioning is varied, including knots such as shell-and-tube heat exchanger, plate heat exchangers Structure is required for occupying very big space., it is necessary to which multiple handpiece Water Chilling Units work at the same time when especially refrigeration requirement is especially huge , it is necessary to arrange enough evaporators in same space as far as possible when could meet cold requirement.

Dry evaporator referred in the coolant channel of evaporator, and refrigerant is in exit evaporating completely, no There are liquid refrigerant, such evaporator is exclusively used in air-cooled handpiece Water Chilling Units, is not suitable for cooling tower, therefore in condenser end segment Space is saved.But evaporator end also needs to save space the structure design, it is necessary to more meticulous.
