Comprehensive above-mentioned and in conjunction with above-mentioned accompanying drawing, the below specifically describes the specific works process of the self-cleaning efficient constant-temperature constant humidity of the utility model energy-saving air central wind cabinet 100, and is as follows:
Described PLC controller controls described exhaust valve 10a and cuts out, described return air inlet 13, fresh wind port 12, the air-valve of air outlet 11 and air-flow balancing valve 8a open, and, described PLC controller is controlled described pressure fan 5 and is started, inside and outside the wind cabinet main body 1, especially wet curtain precooling device 2 both sides, produce pressure reduction, make wind cabinet main body 1 outer high temperature air flow through the moistening wet curtain 22 of porous, enter described wind cabinet main body 1 inside through the air behind described wet curtain 22 moistening and lowering temperatures by described fresh wind port 12, at this moment, the moisture through described wet curtain 22 is back in the described water tank 31 by described backflow water pipe 34.And simultaneously, after the return air air that enters from described return air inlet 13 filters by described primary air screen pack 71 and secondary air screen pack 72 first, again through described chilled water coil 6 coolings.When needs dehumidify, described PLC controller is controlled described compressor 101a and is started, and then whole dehumidification system 101 is worked, described evaporimeter 101d carries out cooling and dehumidifying to the air of sending from described chilled water coil 6, through the original temperature of heating to of described condenser 101b, from air outlet 11, send again after the dehumidifying.When the needs humidification, described dehumidification system 101 quits work, described PLC controller starts described magnetic valve 37, described magnetic valve 37 is opened, described water pump 32 supplies water to described cleaning shower nozzle 4 simultaneously, described cleaning shower nozzle 4 carries out humidification to the return air air through described chilled water coil 6, and the return air air enters described wind cabinet main body 1 inside; Enter and send from described air outlet 11 after the new wind of described wind cabinet main body 1 inside and return air air mix.And recycle realizing for described wet curtain precooling device 2 in the described water tank 31 through the condensate return that produces after 6 coolings of described chilled water coil.
The self-cleaning efficient constant-temperature constant humidity of the utility model energy-saving air central wind cabinet 100 has various modes, different with boreal climate according to south, summer, the pattern in winter in spring and autumn is not identical yet, accurately: 1) when temperature surpasses 25 degrees centigrade, use summer mode, the air-valve fraction of fresh wind port is opened, air outlet 12, the air-valve of return air inlet 13 and air-flow balancing valve 8a standard-sized sheet, exhaust valve 10a closes, new wind enters wind cabinet main body 1 through described wet curtain precooling device 2 coolings, the return air air that return air inlet 13 enters is by the cooling of the water quench in the chilled water coil 6, and described dehumidification system 101 dehumidifies according to the humidity size.2) when temperature during at 10 ~ 25 degrees centigrade, use the spring and autumn pattern, the air-valve standard-sized sheet of fresh wind port 12, the air-valve complete shut-down of return air inlet 13, exhaust valve 10a opens, and air exhauster 10 operations do not have cooling water in the chilled water coil 6, fully by wet curtain precooling device 2 refrigeration.3) when temperature is lower than degree centigrade, use winter mode, wet curtain precooling device 2 is cut off the water, the air-valve fraction of fresh wind port 12 is opened, the air-valve standard-sized sheet of return air inlet 13, and exhaust valve 10a closes, cooling water in the chilled water coil 6 has changed hot water into, and described cleaning shower nozzle 4 is according to humidity size spraying humidification.The self-cleaning efficient constant-temperature constant humidity of the utility model energy-saving air central wind cabinet 100 can also have other patterns, gets final product by the setting of PLC controller, no longer describes in detail at this.
During normal the use, the bottom water leg that the dusts that the water of described water tank 31 flows to wet curtain 22 surfaces and wet curtain 22 surfaces are pooled to wet curtain precooling device 2 together turns back to water tank 31 by backflow water pipe 34 again, and the realization water circuit uses and the automated cleaning of the curtain 22 that wets.After using a period of time, described filter screen 23, wet curtain 22 and described chilled water coil 6 adhere to more dust, and can not clear out fully the time, the opening of can be at short notice controlling described control valve 33 and magnetic valve 37 by described PLC controller is opened to maximum, described water pump 31 supplies water in a large number to described wet curtain 22 and chilled water coil 6, with the dust strong flushing on described wet curtain 22 and the chilled water coil 6, again described control valve 33 and magnetic valve 37 are transferred to the normal position after having washed dust, discharge by magnetic valve sewage draining exit 36 at last, obtain clear water from running water pipe again and can continue to use.
The self-cleaning efficient constant-temperature constant humidity of the utility model energy-saving air central wind cabinet 100 is at the fresh wind port of ordinary central air-conditioner wind cabinet wet curtain precooling device 2 with blower fan to be installed not, the cooling-air that to adopt simple Wet-curtain temperature reducing technology be air cabinet of air conditioner is done preliminary treatment, extraneous high temperature air is lowered the temperature by wet curtain 22 first to be entered in the wind cabinet main body 1 of air-conditioning for behind the cold air of high humility again, simultaneously, a part is cooled off in chilled water coil 6 from the high temperature air that return air inlet 13 enters, thereby the mixing of two-way gas is sent to described air outlet 11 again; And in described wind cabinet body interior described dehumidification system is installed, is utilized described dehumidification system can realize again the air that return air inlet enters is dehumidified.In addition, at described wet curtain precooling device 2 water system 3 is installed, utilize water pump 32, control valve 33 and the backflow water pipe 34 of water system 3 to make described water system 1 form backflow at described wet curtain precooling device 2, can the water of wet curtain precooling be recycled on the one hand, using water wisely, can when needed the output of described control valve 33 be transferred to maximum on the other hand, thereby wet curtain precooling device 2 is carried out automatic cyclic cleaning.As seen, but the self-cleaning efficient constant-temperature constant humidity of the utility model energy-saving air central wind cabinet 100 combine ordinary central air-conditioner wind cabinet temperature control accurately, can dehumidifying, strong adaptability, weatherproof advantage and the wet curtain ring advantage of protecting the efficient humidification of air conditioner energy saving, and can realize all functions of controlled humidity air cabinet of air conditioner, but avoided its highly energy-consuming water consumption, need the deficiency of frequent Manual-cleaning, very easy to use.
