Description

The closed component that is used for evaporator unit

Technical field

Relate generally to of the present invention is used for the evaporator unit of air handling system, and more specifically relates to the relevant closed component of air exhaust openings after the adjusting with evaporator unit.

Background technology

In many commercial air conditionings, heating and ventilating system, the air after the adjusting distributes by air or regulon is discharged into the inner space.For example, the air handling system that often is called split type system of a general type comprises indoor unit and outdoor unit separately.Outdoor unit comprises compressor, heat exchanger and fan.Indoor unit comprises heat exchanger and fan and is called evaporator unit.Be in operation, the inlet of indoor fan by evaporator unit is with air suction evaporator unit and impel air through heat exchanger and leave evaporator unit by the exit opening in it then.

Outdoor fan is pumped into outdoor air in the outdoor unit and makes its process outdoor heat exchanger circulation and get back to environment then.Simultaneously, compressor causes refrigerant fluid to cycle through and circulates between indoor/outdoor heat exchangers.At the indoor heat exchanger place, cold-producing medium absorbs heat with the cooling air from the air through it.Simultaneously, at the outdoor heat exchanger place, air absorbs heat from the cold-producing medium through heat exchanger by heat exchanger.

The split type air-conditioning unit of this type is typically with the cooling capacity manufacturing of wide region.In making such unit, particularly when the unit became bigger, the manufacturing of multiple parts and assembling became and require great effort and trouble.Typically, the unit is big more, and then desired parts are many more, and many more for assembling the desired securing member of all parts.Consider the utmost point wish make and assembling process in minimize the number of the parts and the securing member of requirement.

The housing that is used for evaporator unit generally includes protecgulum and a plurality of shutter that is arranged in the opening that has the air exhaust openings after the adjusting in it, flows from them with the guiding air discharged.Shutter can selectively can be regulated and can be connected to driving mechanism, and driving mechanism is mobile shutter on continuous foundation automatically, so that air is flowed inswept in complex way exhaust openings.

Summary of the invention

The evaporator unit that is used for air handling system comprises housing, and housing has rear board and has the forward part of air intake opening and air exhaust openings.Housing comprises evaporator fan and evaporator coil, and fan causes the air to flow in the inlet opening, being conditioned, and leaves exhaust openings then by evaporator coil.Provide closed component so that the apical margin of back plate and the apical margin of evaporator drain pan are interconnected.Plan is connected to the back plate by the lip and the hook structure of the coupling on back plate and the closure member with closed component respectively.Also plan to fasten in the corresponding opening in the closure member a plurality of vertical blinds are installed by bar separately with a plurality of vertical blinds.The composition of vertical blind is grouped together and selectively can regulates to flow with the air after the guide adjustment such as hope ground and leaves exhaust openings.A plurality of supporting brackets are attached to closure member, and wherein each support has two arms, and arm can be aimed at the surface of condensate drain and another arm has buckling groove rotatably to receive the mounting rod of horizontal louvres.This shutter is connected to stepper motor again, makes to cause in complex way vertical pivot at system's run duration.
