Description

A kind of air conditioner condensate water self adaptation tapping equipment
Technical field
The utility model relates to a kind of condensate drain, more precisely a kind of air conditioner condensate water self adaptation tapping equipment.
Background technology
The air-conditioning unit generally is made up of several parts such as mixing section (new return air mixes), surface cooling section, wind inlet section, wind outlet sections, need add fillter section when cleaning requires, and what wherein realization cooled the effect of drying mainly is surface cooler.Condensed water discharging when surface cooler is positioned at the fans entrance suction side is referred to as drainage by suction; The condensed water discharging that is positioned at blower fan outlet malleation side is called positive pressuring drainage.
When the air-conditioning unit carries out cooling and dehumidifying, the surface cooler surface will produce a large amount of condensed waters, these condensed waters must exclude just can make the surface cooler operate as normal, usually below the surface cooler water-collecting tray is housed, be used for collecting the condensed water that is produced by surface cooler specially, water-collecting tray is taken over discharged to an open type drainage system then.Common condensed water discharging modes mainly contain three kinds: one, flow by gravity formula; Two, water seal (U-shaped curved); Three, mechanical lifting.
The major defect that prior art exists is: during positive pressuring drainage, cause air leakage in the casing; Drainage by suction is not smooth, causes the interior condensed water of air-conditioning box to accumulate breed bacteria; Even spilling water causes leakage accident; During negative pressure, add the auxiliary draining of draining pump and condensed water can be discharged the air-conditioning unit, but coagulate water pond in the unit and must save bit by bit certain water level (making things convenient for pump to suck), still the problem that has breed bacteria, can increase cost and operating cost if increase pump, and the discharging of condensed water can not be included the building automatic control decorum in, does not accomplish real time intelligent control.
Most widely used in the present stage condensed water discharging is U-shaped curved draining.In unit operation, be to guarantee effective discharging of condensed water, it is curved the U-shaped of certain altitude to be set at flowing line, can form in U-shaped is curved and discharges the necessary discrepancy in elevation motive power of condensed water so that discharge condensed water, and do not cause outdoor air to be drawn into unit, and influence the normal discharging of condensed water.But regular meeting in actual engineering practice is because place reason or design and construction personnel's problem causes U-shaped curved insufficient height; fail to form the essential water column discrepancy in elevation; and the flowing line gradient is not enough; sometimes also have counter-slope and raise situation; cause condensed water in the water-collecting tray to overflow and cause the condensed water impeded drainage to the air-conditioning unit; like this when the air-conditioning unit operation; condensed water can ooze around casing; and after unit is out of service; the condensed water that is stored in a large number in the air-conditioning unit casing just can be discharged from the casing slit, causes a large amount of ponding in ground in the machine room.And to being loaded on the unit on the furred ceiling, condensed water water clock problem is then even more serious, and a large amount of condensed waters fall into indoor by furred ceiling, can cause furred ceiling to damage, and indoor machine equipment, office accommodation are wet, and cause property loss.
Particularly need to pay close attention in this problem of clean air conditioner field; clean air conditioner has high requirements to the cleanliness factor of air-conditioning unit; research and develop a kind of draining convenient, drain behind the water not ponding of condense water disk, and the air conditioner condensate water tapping equipment that pours in down a chimney of must not leaking gas after shutting down is extremely urgent.
