    AHU combination models

    1 Model A

    21312232131

    Characteristic:
    The fan postposition, that all of the handling equipment are in the negative pressure section. The unit’s length is short, and convenient for installation. This scheme is applicable for the general systems which have no cleanliness request or the clean systems that the unit’s length is limited.  
    As the figure shown, it is the basic model of the A combination scheme, basic function section includes: mixing box, pre-filter, main filter, cooling coil, heater, humidifier, fan and motor, etc. On this basis, users can also increase or decrease other function sections according to need.

    2 Model B

    465365

    Characteristic:

    The fan preposition, that the main filter and other main parts are in the positive pressure section, this is advantageous to shelter the coil and drain off the condensed water. This scheme is broadly applicable for the clean air conditioning system.
    As the figure shown, it is the basic model of the B combination scheme, basic function section include: mixing box, fan and motor, diffuser, pre-filter, main filter, cooling coil, heater, humidifier, etc. On this basis, users can also increase or decrease other function sections according to need.

    3 Model C

    2345634634

    Characteristic:
    The fan placed in middle position, that the main filter is in the positive pressure section and other parts are in the negative pressure section. This scheme is extensively applicable for the clean air conditioning system.
    As the figure shown, it is the basic model of the C combination scheme, basic function section includes: mixing box, pre-filter, cooling coil, heater, humidifier, fan and motor, diffuser, main filter and outlet section, etc. On this basis, users can also increase or decrease other function sections according to need.

    4 Model D

    354265245623
