Description
Technical field
The utility model relates to a kind of Fresh air handling units, particularly relate to a kind of screen pack is installed after there is Fresh air handling units compared with slight drag simultaneously, belong to air-conditioning HVAC industry category.
Background technology
In central air conditioner system, Fresh air handling units is one of very important parts, its effect is exactly the fresh air in the external world is added to indoor and circulates, central air conditioner system is entered for preventing the impurity in outside air, usually arrange screen pack at the air inlet of Fresh air handling units, due to the restriction of air inlet size, adding the resistance installing screen pack rear air inlet increases greatly, Fresh air handling units import wind speed is caused to exceed the rated wind speed of filter requirement itself, the serious damage causing filter.
Utility model content
For overcoming above-mentioned defect, the utility model aims to provide a kind of impurity that can effectively filter out in outside air, can not cause too large resistance Fresh air handling units again because of screen pack simultaneously.
For achieving the above object, the technical solution adopted in the utility model is: a kind of Fresh air handling units, comprise a cabinet and be placed in the Fans in cabinet, described cabinet is surrounded by an end face, a bottom surface and four sides, described blower fan is placed on bottom surface, the air outlet of described blower fan is towards end face and be connected with the outlet air flange on end face, described cabinet is also with an air compartment outward, the end face of described air compartment is equal with bottom surface with the end face of cabinet with bottom surface, one of them side of described air compartment has an air inlet; One of them side of described cabinet is provided with access door, and its excess-three side of described cabinet is provided with screen pack and cancels coaming plate; Be provided with muffler between the air outlet of described blower fan and outlet air flange, described outlet air flange is also provided with adjusting air valve.
Be provided with a pressure sensor in described cabinet, in described outlet air flange, be provided with an external pressure sensor, described inside and outside pressure sensor, to be connected with control centre signal respectively.
The end face of described cabinet is provided with a maintenance lamp, and described maintenance lamp is electrically connected with the coupled switch on access door.
Have employed Fresh air handling units of the present utility model, owing to the coaming plate of three sides being cancelled and being provided with screen pack, make cabinet can carry out air intake from three faces, do not affecting under airfiltering prerequisite, substantially increase incoming air area, air intake resistance is reduced greatly, alleviates the pressure of air-flow to screen pack, improve the service life of Fresh air handling units.

Detailed description of the invention
As depicted in figs. 1 and 2, the utility model discloses a kind of Fresh air handling units, the Fans 2 comprising a cabinet 1 and be placed in cabinet 1, described blower fan 2 is generally multiple wing type centrifugal blower fan, described cabinet 1 is by an end face 3, the rectangular hexahedron that a bottom surface 4 and four sides 5 surround, described blower fan 2 is placed on bottom surface 4, the air outlet 6 of described blower fan 2 is towards end face 3 and be connected with the outlet air flange 7 on end face 3, the innovative point of Fresh air handling units of the present utility model is mainly that described cabinet 1 is outer and is also with an air compartment 16, the end face of described air compartment 16 is equal with bottom surface 4 with the end face 3 of cabinet 1 with bottom surface, one of them side of described air compartment 16 has an air inlet 8, one of them side 5 of described cabinet 1 is provided with access door 14, usually access door 14 is arranged on this side 5 at the belt pulley place of blower fan 2, so that maintenance, its excess-three side 5 of described cabinet 1 is provided with screen pack 15 and cancels coaming plate, be provided with muffler 9 between the air outlet 6 of described blower fan 2 and outlet air flange 7, described outlet air flange 7 is also provided with adjusting air valve 10.Like this, when Fresh air handling units runs, air-flow first enters air compartment 16 from air inlet 8, after air-flow enters air compartment 16, flow velocity reduces greatly, and flow through screen pack 15 on its excess-three side 5 of cabinet 1 laggard enter blower fan 2, flow out from air outlet 6 in the pressure that adds of blower fan 2 impeller, and finally flow to pipe network through outlet air flange 7.Air inlet 8 wherein on air compartment 16 can be arranged on different sides according to the trend of pipe network.By arranging air compartment 16, being not only convenient to the installation of Fresh air handling units, simultaneously also making air-flow be slowed down before entering cabinet 1, make air flow energy more low speed flow through filter screen 15 stably.
Another innovative point of Fresh air handling units of the present utility model is to be provided with a pressure sensor 11 in described cabinet 1, be provided with an external pressure sensor 12 in described outlet air flange 7, described inside and outside pressure sensor 11,12 is connected with control centre signal respectively.During actual use, by the pressure differential between the inside and outside pressure sensor 11,12 of control centre's Real-Time Monitoring, when pressure differential is excessive, can consider whether screen pack 15 is plugged by foreign material, when pressure differential is too small, can considers that whether screen pack 15 is damaged, and overhaul in time.
For ease of maintenance, the end face 3 of the described cabinet 1 of Fresh air handling units of the present utility model is also provided with a maintenance lamp 13, described maintenance lamp 13 is electrically connected with the coupled switch on access door 14.Namely when opening access door 14, maintenance lamp 13 is opened automatically, and after shutting access door 14, maintenance lamp 13 is closed automatically.
