Description
[technical field]
The invention belongs to the equipment room ventilation technical field, refer more particularly to a kind of control method of indoor air temperature of electric control room.
[background technology]
Along with development and national economy, large-scale metal-working plant increases day by day, and automation degree of equipment is also improving constantly, and the control appliance in the respective electric control machine room is also more and more.Electric controling element generally is assembled in the switch board of standard, each switch board caloric value between 0.5～1.0kW, electric control room caloric value often tens in addition hundreds of kW between.For eliminating the electric control room caloric value, need at the indoor cooling system that installs an air-conditioner of electrical control to get rid of caloric value.In engineering design in the past, air-conditioning equipment often selects for use air-cooled cabinet air-conditioner, water-cooled cabinet air-conditioner, large fan coil pipe " chilled water is from refrigeration station " etc. to dispel the heat.
Because the electrical equipment caloric value is bigger; The area of electric control chamber is less relatively; Very hot at summer condition, even in not too hot season, still there are a large amount of waste heats to get rid of by the electric control room of conventional design; Still need open air-conditioning and get rid of waste heat, keep the normal operating temperature of electric control room.
[summary of the invention]
In order to solve an above-mentioned difficult problem; The present invention provides a kind of control method of indoor air temperature of electric control room, and control method of the present invention has solved caloric value or the room air that electric control room air-conditioning temperature-reducing system long-play produced and regulated problem automatically.
For realizing the foregoing invention purpose, the present invention adopts following technical scheme:
A kind of control method of indoor air temperature of electric control room; Said control method disposes circulation air path 3 above electric control room 10 is indoor; Circulation air path 3 is by furred ceiling 12 shieldings of said circulation air path 3 belows; Circulation air path 3 is provided with a plurality of air outlets or suction opeing 14, and these air outlets or suction opeing 14 are arranged on the top of electrical control cabinet 11; Air inlet or air outlet 14 at circulation air path 3 dispose blower fan 4, and the rotating of blower fan 4 realizes air intake or exhausting, and the size of intake or exhausting amount realizes that through the rotating speed of blower fan 4 said rotating or rotating speed are controlled blower fan 4 by frequency converter; One section extension of circulation air path 3 is arranged on the top of air conditioner 1, configuration air channel valve A2 in the circulation air path of said extension; The other end of blower fan 4 connects extension air channel 6; It is outdoor that extension air channel 6 extends to electric control room; In extension air channel, dispose air channel valve B5 near blower fan 4 places; Configuration adjustment air channel valve C7 outside the extension air channel of air channel valve B5 front end; Regulate air channel valve C7 and be connected with 13 air channels, workshop, workshop 13 air themperatures are indoor through transporting to electric control room 10 through air channel valve B5 again after regulating air channel valve C7 and outdoor 8 air themperatures are mixed adjusting in extension air channel 6, or close and regulate air channel valve C7 directly transports to outdoor 8 air themperatures the said indoor air temperature of electric control room of electric control room 10 indoor realizations through air channel valve B5 control method.
The control method of described indoor air temperature of electric control room, the air outlet or the suction opeing 14 that are provided with on the said circulation air path 3 are at least two.
The control method of described indoor air temperature of electric control room, said blower fan 4 is a two-way blower fan 4.
Because adopt aforesaid technical scheme, the present invention has following superiority:
The control method of indoor air temperature of electric control room of the present invention;
1, makes full use of the cold of outdoor air, significantly reduced the running time of air conditioner;
Because the power that fan operation consumes is well below the power of air conditioner, control method operating cost of the present invention is lower than the operating cost of pure air-conditioning system.
2, owing to the running time that has reduced air conditioner, with the service life that prolongs air conditioner.
3, owing to send outdoor fresh air at transition season and winter to electric control chamber, the indoor air circulation of electric control room is accelerated, age of air shortens greatly, has promoted the indoor air quality of electric control room.
4, in the workshop that needs forced draft; Like the aluminium foil workshop, control method of the present invention can directly be discharged in the workshop by the hot blast that electric control room is indoor, has made full use of waste heat; Reduce heating amount and workshop air output, saved the operating cost of whole ventilating system.

[specific embodiment]
Can explain in more detail that through following embodiment the present invention, the present invention are not limited to following embodiment, open the object of the invention is intended to protect all variations and the improvement in the scope of the invention;
In conjunction with Fig. 1; The control method of indoor air temperature of electric control room of the present invention disposes circulation air path 3 above electric control room 10 is indoor; Circulation air path 3 is by the furred ceiling 12 conduct shieldings of its below; Circulation air path 3 is provided with a plurality of air outlets or suction opeing 9, and these air outlets or suction opeing 9 designs are above electrical control cabinet 11; Air inlet or air outlet 9 at circulation air path 3 dispose blower fan 4, and the rotating of blower fan 4 realizes air intake or exhausting, and the size of intake or exhausting amount realizes that through the rotating speed of blower fan 4 said rotating or rotating speed are controlled blower fan 4 by frequency converter; One section extension of circulation air path 3 is arranged on the top of air conditioner 1, configuration air channel valve A2 in the circulation air path 3 of this section extension; The other end of blower fan 4 connects extension air channel 6; It is outdoor that extension air channel 6 extends to electric control room 10; In extension air channel 6, dispose air channel valve B5 near blower fan 4 places; Configuration adjustment air channel valve C7 outside the extension air channel 6 of air channel valve B5 front end; Regulate air channel valve C7 and is connected with 13 air channels, workshop, workshop 13 air themperatures are indoor through transporting to electric control room 10 through air channel valve B5 again after regulating air channel valve C7 and outside air temperature is mixed adjusting in extension air channel 6, or closing adjusting air channel valve C7, direct that outdoor 8 air themperatures are transported to electric control room 10 through air channel valve B5 is indoor.
The control method of the described indoor air temperature of electric control room of embodiment of the present invention; When outside air temperature is relatively lower; Air conditioner 1 can be out of service; It is indoor that unlatching blower fan 4 is sent outdoor low latitude temperature degree into electric control room 10, should close this moment and regulate air channel valve C7, and air draft is discharged from the exhaust outlet of electric control room 10.
When outside air temperature is very low; Outdoor temperature like the Northeast winter is just very low; To open this moment and regulate air channel valve C7; It is indoor to transport to electric control room again after outside air temperature being mixed with the workshop air temperature regulate through air channel valve B5, can guarantee that the air themperature of importing is fit to the temperature requirement of electric control room.
