Abstract
The utility model discloses a kind of central air-conditioning room return air blowing system, including fan coil, water inlet pipe and return pipe, the air outlet and return air inlet that are arranged in the top furred ceiling in room, the air outlet and return air inlet are connect with the air outlet of air-treatment case and return air inlet respectively;The fan coil is longitudinally disposed and is fixed on the middle position on the door opposite wall top in the room, and the water inlet pipe and return pipe of the fan coil are connect with the export and import of the chilled water of handpiece Water Chilling Units evaporator respectively.The cold wind that the utility model is blown out using longitudinally disposed fan coil, forms swirling eddy in the room, and due to density, the bacterium etc. that swirling eddy is centrally formed is brought into return air inlet, to which air quality is improved;And room interior air-flow Tissue distribution is uniform, cooling rate is fast, and the performance of air-conditioning system improves.
Description
Technical field
The utility model is related to refrigeration and air-conditioning technical fields, and in particular to a kind of central air-conditioning room return air blowing system.
Background technology
Existing central air-conditioning room return air blowing system, fan coil are all lateral setting, the cold air formed in room
Flow field mostly flows up and down, and air current composition is uneven, and the runnability of air-conditioning system declines.Meanwhile the bacterium etc. in room
Room cannot be taken out of in time, aggregation for a long time can cause the air quality in room to decline, and influence health.
Utility model content
The purpose of this utility model is to be directed to technological deficiency existing in the prior art, provides a kind of center of clean and effective
Air-conditioned room return air blowing system ensures the quality of space air to further increase the runnability of air-conditioning system.
Technical solution is as follows used by realize the purpose of this utility model:
A kind of central air-conditioning room return air blowing system, including fan coil, the air-supply that is arranged in the top furred ceiling in room
Mouth and return air inlet, the air outlet and return air inlet are connect with the air outlet of air-treatment case and return air inlet respectively;The fan unit
It manages longitudinally disposed and door that is being fixed on room opposite wall top middle position, the water inlet pipe of the fan coil and returns
Water pipe is connect with the export and import of the chilled water of handpiece Water Chilling Units evaporator respectively.
The supply grille of the fan coil is vertically arranged, and can left-right rotation adjusting.
The cold wind that the utility model is blown out using longitudinally disposed fan coil, forms swirling eddy in the room, due to
The reason of density, the bacterium etc. that swirling eddy is centrally formed are brought into return air inlet, to which air quality is improved;And this practicality
Novel central air-conditioning room return air blowing system, room interior air-flow Tissue distribution is uniform, and cooling rate is fast, the performance of air-conditioning system
It improves.
Description of the drawings
Fig. 1 is the schematic diagram of the central air-conditioning room return air blowing system of the utility model;
Fig. 2 be shown as Fig. 1 along A-A to sectional view.
Specific implementation mode
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
Shown in Fig. 1-2, a kind of central air-conditioning room return air blowing system, including:
Air outlet 1, return air inlet 2, fan coil 4, the fan coil 4 have water inlet pipe 5 and return pipe 6;Wherein, described
Air outlet 1 is connect with the air outlet of air-treatment case, is arranged in the top furred ceiling in room 3;The return air inlet 2 and air-treatment
The return air inlet of case connects, and is similarly disposed in the top furred ceiling in room 3;The fan coil 4 is longitudinally disposed and is fixedly mounted
Middle position on the door opposite wall top in room 3, the water inlet pipe 5 of the fan coil 4, return pipe 6 respectively with cooling-water machine
The export and import connection of the chilled water of group evaporator.
Specifically, the supply grille of the fan coil 4 is vertically arranged, and can left-right rotation adjusting.
Wherein, the size of the fan coil 4 can be determined according to room-size and refrigeration duty come specific.
When room needs to provide cold wind, start air-conditioning, the cool air that fan coil 4 blows forms rotation in room 3
Turn air current composition, due to density reasons, the bacterium that swirling eddy is centrally formed is brought into return air inlet, to which air quality is carried
It is high;And the central air-conditioning room return air blowing system of the utility model, room interior air-flow Tissue distribution is uniform, and cooling rate is fast, empty
The performance of adjusting system improves.
The above is only the preferred embodiment of the utility model, it is noted that for the general of the art
For logical technical staff, without departing from the principle of this utility model, several improvements and modifications can also be made, these change
The scope of protection of the utility model is also should be regarded as into retouching.
