Utility model content
In order to overcome the existing unitary air handling unit deficiency for ventilating during operating mode, this utility model provides a kind of underground engineering air intake/air-treatment combined type unit, can be greatly reduced for ventilate operating mode time unit energy consumption.
The technical solution of the utility model is achieved in that
Underground engineering air intake/air-treatment combined type unit, including housing, is in turn divided into wind inlet section, air-treatment section and fan section by air-flow trend in housing.Air inlet valve and roughing efficiency air filter it is provided with in wind inlet section;Surface cooler and water fender it is provided with in air-treatment section;Blower fan it is provided with in fan section;It is characterized in that: be additionally arranged bypass wind inlet section, bypass wind inlet section is arranged on the housing of fan section place, and directly internal with fan section connect, bypass air inlet valve it is installed in bypass wind inlet section and bypasses roughing efficiency air filter, bypassing the air inlet valve in air inlet valve and wind inlet section and select one and open.
Compared with prior art, this utility model has the advantages that
When be used for ventilating operating mode time, traditional unitary air handling unit, new wind enters back into fan section after need to overcoming the resistance of wind inlet section (containing air inlet valve and roughing efficiency air filter) and air-treatment section (containing surface cooler and water fender), can cause unnecessary energy resource consumption.And new wind of the present utility model is directly entered fan section from bypass wind inlet section (containing bypass air inlet valve and bypass roughing efficiency air filter), have only to overcome the resistance of bypass wind inlet section, compared to tradition ventilation pattern, this structure need not by air-treatment section, this make for ventilate operating mode time, under same ventilation, air intake resistance of the present utility model is air conditioning unit much smaller than conventional ASSEMBLE, and operation energy consumption is also significantly less than traditional unitary air handling unit.And in the practical application of underground engineering, the unit being placed in ad hoc air intake/air-treatment machine room is direct air intake from machine room space, it is not necessary to special blast pipe.Therefore this utility model increases extra piping facility without because adding bypass wind inlet section, also there is no increase to the requirement of installing space is air conditioning unit relative to conventional ASSEMBLE, the place of conventional rack can be used just can to use this utility model.
