Problems solved by technology

[0003] However, because the existing fan filter unit is usually installed on the ceiling of the production workshop, and at the same time it must meet the noise requirements in the production workshop, the existing fan filter unit can generally only provide an external residual pressure of about 90Pa. After overcoming the resistance of the dry surface cooler in the clean room air circulation system and the resistance of the raised floor, the available pressure provided to the chemical filter is very small, which limits the thickness of the adsorbent layer in the chemical filter to a certain extent, resulting in The service life of the chemical filter is very short. After a period of use, the adsorbent layer is saturated, and the chemical filter needs to be replaced. Frequent replacement of the chemical filter will affect the continuous working time of the fan filter unit, which is not conducive to the continuity of production in the production workshop.

Embodiment 1

[0034] Example one, as figure 1 As shown, the air handling unit provided by Embodiment 1 of the present invention includes: a unit casing 10 having an air inlet and an air outlet, a fan 40 arranged in the unit casing 10, a dry surface cooler 20 and a chemical filter 30 ;in,

[0035] The dry surface cooler 20, the chemical filter 30 and the fan 40 are arranged in sequence along the air flow direction from the air inlet to the air outlet.

[0036] In this embodiment, the dry surface cooler 20, the chemical filter 30 and the fan 40 are sequentially installed in the same unit casing 10, that is, the air handling unit has its own fan, so that the chemical filter 30 can use a thicker adsorbent layer, thereby prolonging the service life of the chemical filter, thereby increasing the continuous working time of the air handling unit, and at the same time controlling the temperature in the production workshop.

[0037] Preferably, the adsorbent layer of the above-mentioned chemical fi...

Embodiment 2

[0042] Example two, as figure 2 As shown, the air handling unit provided by Embodiment 2 of the present invention includes: a unit casing 10 having an air inlet and an air outlet, a fan 40 arranged in the unit casing 10, a dry surface cooler 20, and two chemical filters 30, 31; among them,

[0043] The dry surface cooler 20, the chemical filter 30, the chemical filter 31 and the blower 40 are arranged in sequence along the flow direction of the airflow from the air inlet to the air outlet.

[0044] In this embodiment, the dry surface cooler 20, the chemical filter 30, the chemical filter 31 and the fan 40 are installed in the same unit casing 10, that is, the air handling unit has its own fan, so that the air handling unit can use two A chemical filter, and each chemical filter can use a thicker adsorbent layer, which increases the saturation time of the adsorbent layer, thereby prolonging the service life of the chemical filter, thereby increasing the continuous working tim...

Embodiment 3

[0048] Example three, as Figure 5 As shown, the air handling unit provided by Embodiment 3 of the present invention includes: a unit casing 10 having an air inlet and an air outlet, a fan 40 arranged in the unit casing 10, a dry surface cooler 20, and three chemical filters 30, 31, and 32; of which,

[0049] The dry surface cooler 20 , the chemical filter 30 , the chemical filter 31 , the fan 40 and the chemical filter 32 are sequentially arranged in the unit housing 10 along the air flow direction from the air inlet to the air outlet.

[0050] In this embodiment, the dry surface cooler 20, the chemical filter 30, the chemical filter 31, the fan 40 and the chemical filter 32 are sequentially arranged in the same unit casing 10, that is, the air handling unit has its own fan, so that the air treatment unit The unit can use three chemical filters, and each chemical filter can use a thicker adsorbent layer, which increases the saturation time of the adsorbent layer, thereby pro...
