Accompanying drawing explanation
Accompanying drawing 1 is a kind of logic control schematic diagram of the present invention.
Accompanying drawing 2 is the system schematic of constant humidity perseverance oxygen of the present invention.
Detailed description of the invention
Below by embodiment, and combine accompanying drawing, technical scheme is described in further detail.
Embodiment: one constant temperature and humidity perseverance oxygen air conditioning system of the present invention, as shown in accompanying drawing 1, accompanying drawing 2, it includes the handpiece Water Chilling Units for air conditioning system constant temperature and capillary tube；For new wind frequency conversion dehumidifier 5, the dew point temperature controller of air conditioning system constant humidity, for the CO of air conditioning system perseverance oxygen2Transmitter, total-heat exchanger 1, and for regulating the blower fan 6 of air-flow；The intake air way outlet of total-heat exchanger 1 connects frequency conversion dehumidifier 5, and exhaust passage entrance accesses blower fan 6；It is characterized in that: check valve 2 is set on the pipeline between total-heat exchanger 1 and frequency conversion dehumidifier 5, the pipeline between total-heat exchanger 1 and blower fan 6 arranges air draft butterfly valve 4；Pipeline before check valve 2 outlet and the pipeline before air draft butterfly valve 4 entrance arrange connecting pipe, and arrange return air butterfly valve 3 on this connecting pipe.
The pipeline opening that new wind frequency conversion dehumidifier 5 is passed through room arranges exhaust apparatus 7, and exhaust apparatus 7 is arranged at room low level.
Exhaust apparatus 7 has support body, and support body is turnover folding structure；Exhaust apparatus 7 arranges some air outlets, and air outlet is distributed across on support body, it is simple to user, according to the interior space, overturns or fold support body, regulates air-out angle and direction, air-out height is increased or decreased, can obtain effect of preferably blowing.
The pipeline opening that new blower fan 6 is passed through room arranges air intake device 8, and air intake device 8 is arranged on top, room, and its port of export arranges guard.
The capillary tube connected with handpiece Water Chilling Units is arranged at top, room.
Arranging a casing at new wind frequency conversion dehumidifier 5 port of export, the built-in flexible bag of casing, flexible bag arranges inlet and outlet, respectively by pipeline communication new wind frequency conversion dehumidifier 5 and room；The outlet of flexible bag arranges the expansion when air pressure increases and exports bore, shrinks the elastomer of outlet bore when air pressure reduces.Before import air intake, outlet is in contraction state, and outlet bore is the least or completely closes；When import air intake, air intake increases in flexible bag, and outlet air-out is less, and flexible bag is expanded, until flexible bag bag is resisted against cabinet wall, not further expansion, bag internal gas pressure pressure rises thereafter, along with the rising of air pressure, outlet bore is expanded gradually, and outlet air quantity is also gradually increased.After this supercharging output gas, the distinguished and admirable speed formed evenly, the comfort in enhanced room；Flow velocity faster, increases indoor air-out distance, accelerates the flowing of indoor gas, also accelerates the replacing of indoor gas.
As selectable preferred version, the elastomer periphery of flexible bag sets annular groove, sets ring spring in annular groove.Ring spring is looped around elastomer periphery, can round, two weeks or more than.
Handpiece Water Chilling Units connects capillary tube by pipeline, and capillary tube is mainly arranged in the top in room, for the constant temperature of air conditioning system.Dewpoint controller monitors temperature and the air dew point in each room, when dew point is less than setting value higher than setting value and temperature, open the electrodynamic valve on the pipeline being passed through this room, open handpiece Water Chilling Units simultaneously, feed the water into the capillary tube in this room, heat exchange is made with the air in this room by capillary tube, so that the air cooling-down in this room；After handpiece Water Chilling Units is opened, by the temperature of sensor detection chilled water backwater, when the temperature of chilled water backwater is less than setting value, handpiece Water Chilling Units is shut down.
CO2Transmitter i.e. carbon dioxide transmitter, total-heat exchanger, for the permanent oxygen of air conditioning system.CO2Transmitter works, and i.e. opens air-supply after total-heat exchanger energising.
New wind frequency conversion dehumidifier, dew point temperature controller, for the constant humidity of air conditioning system.The temperature in each room of dew point temperature controller monitoring and air dew point, when dew point is less than setting value higher than setting value and temperature, open the electrodynamic valve on the pipeline being passed through this room, blow in room；When dew point is higher than setting value higher than setting value or temperature, close electrodynamic valve, out-of-blast.For new wind frequency conversion dehumidifier, when the air-out humidity of new wind frequency conversion dehumidifier is higher than setting value, new wind frequency conversion dehumidifier raising frequency；When the air-out humidity of new wind frequency conversion dehumidifier is less than setting value, the frequency reducing of new wind frequency conversion dehumidifier.
Blower fan, check valve, air draft butterfly valve, return air butterfly valve, be used for regulating air-flow.CO2Gas concentration lwevel in transmitters sense room, during less than setting value, close air draft butterfly valve, open return air butterfly valve, the wind that blower fan goes out is again introduced into intake stack, the air temperature that blower fan goes out is identical with indoor, again with, both played the effect of regulation air-flow, running efficiency of system can be improved again, reduce system operation cost；During higher than setting value, opening air draft butterfly valve, close return air butterfly valve, the wind that blower fan is discharged is discharged through total-heat exchanger, with total-heat exchanger heat exchange, can improve the efficiency of system when discharging.Setting value can be a scope, say, that time in the range of, air intake and air draft normally work, outside scope, lower limit depending on low scope is also above the upper limit of scope, wind path is changed by air draft butterfly valve, return air butterfly valve, thus in regulating air-flow, the exchange velocity of gas in change room.
After energising, total-heat exchanger, new wind frequency conversion dehumidifier, blower fan are opened；Handpiece Water Chilling Units is controlled by dew point temperature controller, and whether room temperature and air dew point according to detection reach setting value；When i.e. dew point is less than setting value higher than setting value and temperature, open handpiece Water Chilling Units.
