Background technique
Heat exchanger in air conditioner by long-term use after, performance degradation can be led to because of surface dust accumulation.Heat exchanger is in reality
Actual performance variation in use process can not will detect heat exchanger through length by the performance detection for new heat exchanger
Performance degradation degree after phase use, and need that detection can be completed in a short time.In order to meet the new heat exchange of quickly detection
Device by long-term use after performance degradation degree, need to propose that heat exchanger that can be practical accelerates dust accumulation test method, may
Basic fundamental route be, by building the high concentration dusty circumstances of thousand times of natural environments of a dust concentration, to allow heat exchanger
A few hours are run in the dusty circumstances, are come in simulating natural environment using the dust accumulation situation after the several years.
In order to guarantee that it is repeatable that the performance degradation test result after the accelerated dust accumulation of heat exchanger has, in dust-contained airflow
Dust concentration is uniform and stable be it is crucial, the dust-contained airflow for blowing to heat exchanger surface must satisfy two conditions: 1) heat exchanger is windward
Dust concentration at face in dust-contained airflow keeps uniform in each region of heat exchanger surface；2) at heat exchanger windward side in dust-contained airflow
Dust concentration entirely accelerate the dust accumulation testing time section in keep stablize.The problem of high concentration dusty circumstances are easy to produce be,
The aerial dust particle that suspends gradually is sunk under the effect of gravity, and the dust concentration along gravity direction is distributed in incremental,
Cause the dust concentration in each region in heat exchanger windward side uneven；And with the progress for accelerating dust accumulation process, heat exchanger surface

As defined in " requirement of Long-Term Energy Saving of Air Conditioners assessment technique " (CQC9202-2012) that card center is promulgated in May, 2012.The party
Method for accelerate dust accumulation test basic procedure be: by heat exchanger exemplar built-in test air duct, be installed on tunnel inlet to
Material machine persistently supplies dust；The dust for being sprinkled into air duct passes through heat exchanger exemplar with air duct interior air-flow, is partially deposited on sample surface,
Remaining continues that air duct is discharged with air-flow.The program has the disadvantage that: in accelerating dust accumulation test process, only considering in a short time
Given total dust is blown into heat exchanger surface, does not consider to blow to the uniform of dust concentration in the dust-contained airflow of heat exchanger surface
Property and stability, so that the performance degradation test result repeatability after the accelerated dust accumulation of heat exchanger reduces.
Therefore, those skilled in the art, which is dedicated to developing, a kind of can be realized the uniform and stable heat exchanger of dust concentration
Accelerate dust accumulation test device, after guaranteeing the accelerated dust accumulation of heat exchanger by accurately controlling the dust concentration of heat exchanger windward side
Performance degradation test result has repeatability.
