For this present situation, necessary traditional air curtain system is improved so as to the operating mode that works can be more Close to ideal operating mode, improve barriering efficiency, improve inorganization and ooze wind condition.
Utility model content
The purpose of this utility model is to provide a kind of self-regulation air curtain system it is intended to be used for solving existing air curtain The not good problem of system barriering efficiency.
This utility model is achieved in that
This utility model provides a kind of self-regulation air curtain system it is characterised in that including: air curtain unit;It is placed in outdoor First pressure sensor, for real-time monitoring ambient atmospheric pressure value and be transferred to controller;Second pressure disposed within Sensor, for real-time monitoring room air pressure value and be transferred to controller;Controller, according to the ambient atmospheric pressure obtaining Value and room air pressure value calculate its pressure difference value, and control the rotating speed of air curtain unit according to indoor and outdoor air pressure difference value.
Further, described air curtain unit has adjustable draught for shutter, and described controller is according to indoor and outdoor pressure difference value control Make the flow angle of described adjustable draught for shutter.
Further, the flow angle of described adjustable draught for shutter can also be towards outside towards indoor.
Further, described air curtain unit is installed on above the door opening of indoor, described first pressure sensor and described The installation site of two pressure transducers is above described air curtain unit.
Further, described controller is installed on indoor and is located above described air curtain unit.
Further, described air curtain unit includes multiple air curtains, and described controller controls multiple described air curtains simultaneously.
This utility model has the advantages that
This utility model self-regulation air curtain system can record indoor and outdoor air according to outer pressure transducer disposed within Pressure value and adjust the air output of air curtain unit according to the pressure difference value of indoor and outdoor air, realize air curtain unit air supply parameter With mating of indoor and outdoor surroundingses parameter, raising barriering efficiency, reduce inorganization infiltration air quantity, and then reduce air conditioning energy consumption, improve Indoor thermal comfort.

Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work The all other embodiment being obtained, broadly falls into the scope of this utility model protection.
As depicted in figs. 1 and 2, this utility model embodiment provides a kind of self-regulation air curtain system, comprising: air curtain unit 1, for producing air curtain at door opening;It is placed in the first pressure sensor 2 of outdoor, for real-time monitoring ambient atmospheric pressure value And it is transferred to controller 4;Second pressure sensor 3 disposed within, for real-time monitoring room air pressure value and be transferred to Controller 4;Controller 4, is believed with described first pressure sensor 2, described second pressure sensor 3 and described air curtain unit 1 Number connect, its pressure difference value is calculated according to the ambient atmospheric pressure value obtaining and room air pressure value, and according to indoor outer space Atmospheric pressure difference controls the rotating speed of air curtain unit 1, thus controlling the air output of air curtain unit 1, indoor and outdoor air pressure difference value is got over Greatly, control the rotating speed of described air curtain unit 1 bigger.
As depicted in figs. 1 and 2, further, described air curtain unit 1 has an adjustable draught for shutter 5, described controller 4 Control the flow angle of described adjustable draught for shutter 5 according to indoor and outdoor pressure difference value, the flow angle of described adjustable draught for shutter 5 can So that described adjustable hundred can also be controlled towards outside when ambient atmospheric pressure is less than room air pressure towards indoor The flow angle in leaf air port 5, towards outside, when ambient atmospheric pressure is more than room air pressure, controls described adjustable BAIYE The flow angle in air port 5, towards indoor, can realize preferable barriering effect under different indoor and outdoor air situations.Described Air curtain unit 1 is installed on above the door opening of indoor by air curtain fixing device 6, air port down, described first pressure sensor 2 It is above described air curtain unit 1 with the installation site of described second pressure sensor 3, to avoid air curtain unit 1 air-out to first Pressure transducer 2 and the impact of second pressure sensor 3.Described controller 4 is installed on indoor by controller fixing device 7 And be located above described air curtain unit 1.Described air curtain unit 1 includes at least one air curtain, when described air curtain has multiple, Described controller 4 controls multiple described air curtains simultaneously.
