Abstract

A four-cross air-treatment unit comprises a draught fan, a chassis, air feeding holes, a framework, a filtration air return hole and a heat exchanger, wherein, the draught fan fixed at the chassis is low noisy, single air inlet, no air casing and centrifugal, the air return hole is arranged at an upper part or a lower part of the draught fan according to the air inlet condition, the heat exchanger takes a configuration of L, a water inlet pipe and a water outlet pipe are external-jointed via a three-cross terminal, and the configuration takes a shape of ring, the heat exchanger is arranged around the chassis and is relative to the four air feeding holes which can be connected with external air holes or can feed air directly as a louver window.

Description

Four air-out air-treatment units

Technical field

The utility model product belongs to the terminal airhandling equipment of central air-conditioning.

Background technology

For a long time, hanging air-treatment unit is confined to blow before the air intake of back in the air conditioner industry, by width that strengthens unit and the draught area that highly guarantees heat exchanger, and face velocity is at 2-3m/s, produce bigger noise when air is flowed through heat exchanger fin, can not satisfy the needs of normal work of people and living environment.Arrange number more for a long time when heat exchanger, windage and water resistance are all bigger, and the heat exchange effect descends.

In order to overcome the deficiencies in the prior art, the utility model provides a kind of four air-out air-treatment units, to overcome the defective of conventional rack, makes every effort to super-silent supercool heat performance.

The technical solution of the utility model is achieved in that unit is by blower fan, base, air outlet, framework, filtration return air inlet, compositions such as heat exchanger; Blower fan selects for use low noise list air intake not have crust of weathering centrifugal blower, be fixed on the unit base, condition according to air intake, return air inlet can be arranged on upside or downside, heat exchanger is made into L shaped structure, and its water inlet pipe and water outlet pipe converges external by three-way connection, forms whole loop configuration, be positioned over base around, corresponding with four air outlets; Four air outlets of unit can external air port, also can make shutter and directly blow.

The beneficial effects of the utility model are: change traditional one-sided air-supply into multi-faceted air-supply, the air-supply wind speed is reduced to below the 1.5m/s, thereby reduce the air-supply noise greatly, adopt no crust of weathering blower fan simultaneously, form plenum chamber in the air supply section, play the noise elimination noise reduction effect, make whole unit reach the effect of super-silent operation.Flat plate heat exchanger is changed system into the circular heat exchanger structure, not only reduced the head-on wind resistance, and make heat exchange more abundant, more help realizing energy-conservation purpose.

Description of drawings:

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a plan structure schematic diagram of the present utility model

1 blower fan, 2 bases, 3 air outlets, 4 frameworks, 5 filter return air inlet, 6. heat exchanger, 7 threeways among the figure.

The specific embodiment

As shown in the figure; Four air-out air-treatment units select for use low noise list air intake not have crust of weathering centrifugal blower (1), are fixed on the unit base (2), according to air-inlet condition, will filter return air inlet (5) and be arranged on downside.Two heat exchangers (6) are made into L shaped structure, and its water inlet pipe and water outlet pipe converges external by threeway (7) joint, be positioned over base around, corresponding with four air ports.Four direction around the unit is made air outlet (3), can outer air duct, and also can make shutter and directly blow, so just constituted the super usefulness air-treatment unit of multi-faceted air-supply.

Claims

1, a kind of four air-out air-treatment units are mainly by blower fan, base, air outlet, framework, filtration return air inlet, compositions such as heat exchanger; It is characterized in that blower fan selects for use low noise list air intake not have crust of weathering centrifugal blower, be fixed on the unit base that according to the condition of air intake, return air inlet is arranged on the upside or the downside of blower fan; The blower fan heat exchanger is made into L shaped structure, and its water inlet pipe and water outlet pipe converges external by three-way connection, forms whole loop configuration; Be positioned over base around, corresponding with four air outlets.

2, according to the described four air-out air-treatment units of claim 1, it is characterized in that four air outlets of unit can external air port, also can make shutter and directly blow.
