Valve；
Heat exchange coil runs positive pressure section with equipment by exhaust valve, pressure hose and connection is connected, which is two-way lead
Logical switch valve；
Heat exchange coil runs negative pressure section with equipment by drain valve, pressure hose and connection is connected.
Further, the equipment operation positive pressure section of the large-scale air processing unit is specially equipment air outlet position, greatly
The equipment operation negative pressure section of type air-treatment unit is specially equipment air inlet position.
Further, the air pressure of the equipment operation positive pressure section are as follows: 50Pa to 1500Pa, equipment run the air pressure of negative pressure section
Are as follows: -600Pa to -50Pa.
Compared with the existing technology, no external pressure self-draining arrangement described in the utility model has the advantage that
(1) drainage arrangement of the present invention does not need other purchase of equipment, by itself generating in equipment running process
Pressure difference drain water automatically, structure is simple and convenient to operate, and is not needed in addition to be arranged and is needed exhaust or the drainage arrangement of power；
(2) change by a relatively large margin in equipment running process will not occur due to pressure difference for drainage arrangement of the present invention
Change, therefore can purge for a long time, can not only drain, the humid air inside coil pipe can also be excluded, prevent wet atmospheric corrosion
Copper pipe；
(3) air of drainage arrangement sucking of the present invention is the air at internal circulation system air outlet, the sky of discharge
Gas has been discharged into the air inlet of internal circulation system, does not influence the air quantity of the circulatory system, will not influence the purification of air processed
Grade.
