Accompanying drawing 1 is a structural representation of the present utility model.
Operation principle of the present utility model is as follows:
Extraneous hot and humid air is carried by air intake blower fan 1, enters into the air intake cooling coil 9 of three stream heat exchangers, 6 heat exchanging chambers 7.In heat exchanging chamber 7, carry out heat exchange with building internal haze air that extract out by air draft blower fan 2, hypoxemia and high pernicious gas content.Because air themperature is the normal temperature of setting substantially in the building, therefore can absorb the air intake heat, makes it to drop near normal temperature in the building.Air intake air after the cooling enters in the dehumidifying chamber 8.Refrigeration heat converter 4 is arranged in dehumidifying in the chamber 8,, be further cooled when cooling to after air intake air near design temperature enters.Because after the cooling of air intake air, airborne moisture is in hypersaturated state, in dehumidifying chamber 8, condense into water, flow to the bottom, discharged from discharge outlet 11.The relative humidity that is in low temperature is 100% air intake air enters into heat exchanging chamber 7 from dehumidifying 8 bottoms, chamber air intake heat(ing) coil 10.In air intake heat(ing) coil 10, carry out heat exchange, absorb the heat (air draft absorbs heat from air intake cooling coil 9) of air draft with air draft.Make temperature recovery, when reaching the control design temperature, send in the building, because temperature recovery reduces relative humidity.Satisfied the requirement of ventilation air intake.
In the utility model, central control computer 18 adopts the mode of timing scan under the control of control program, constantly measure air intake data and environmental data.As when central control computer 18 is gathered EATs, at first send the address gating signal of the measurement adaptation module 19 that gating links to each other with EAT sensor 12 by the standard serial communication interface.Standard industrial control 17 selects the signal backgating to measure adaptation module 19 accordingly receiving this ground.This measures adaptation module 19 by behind the gating, the EAT analog quantity that is measured by EAT sensor 12 anti-central control computer 18 of sending back to after the A/D conversion, finishes the data acquisition task.The collecting method of the temperature of air intake humidity and controlled environment, humidity and harmful gas concentration similarly, central control computer 18 sends the address gating signal of the measurement adaptation module that the gating respective sensor connected by the standard serial communication interface, receives backgatings by standard industrial control 17 and measures adaptation module accordingly.Corresponding measure adaptation module by gating after, parameter anti-central control computer 18 of sending back to after the A/D conversion that respective sensor is measured, finish gatherer process.Central control computer 18 compares with standard control model after collecting air intake parameter and ambient parameter, makes control decision.As when needs increase ventilation, central control computer 18 sends by the standard serial communication interface that gating links to each other with the three terminal device control end of air intake blower fan 1 and to the address gating signal of its control adaptation module of controlling 24, receives backgating control corresponding adaptation module 24 by standard industrial control 17.This control adaptation module 24 is by behind the gating, the ventilation data that central control computer 18 is sent by the standard serial communication interface again, receive the required control signal of three terminal device that latchs and be converted to air intake blower fan 1 by control adaptation module 24, change the operating mode of air intake blower fan 1.Central control computer 18 also can adopt identical method to change the operating mode of air draft fanman or refrigeration compressor according to the control model.
The utility model adopts the method for cryogenic temperature condensation dehumidifying, and the air intake air themperature is reduced to below the required design temperature, makes it condensation and removes unnecessary moisture content, reaches the purpose of dehumidifying.Needed air intake humidity can be controlled by the difference of air intake design temperature and dehumidifying chamber condensation temperature.The temperature difference is big more, and the relative humidity that obtains is more little.Carry out heat exchange twice with the dehumidifying back before using the dehumidifying of air draft and air intake, make the consumption of air conditioner refrigerating energy seldom.And the utility model is a kind ofly to dehumidify continuously naturally, and the consumption of no drier does not have the management maintenance problem of runtime yet.The utility model adopts central control computer, the version of standard industrial control and this electromechanical integration of various adaptation module, that can coordinate very much controls ambient parameter, after in central control computer, storing complicated control strategy, can adapt to controlled parameter individual event, wide variation.And control is coordinated fast.
Refrigeration and heat radiator 3 in the utility model, refrigeration heat converter 4 and refrigeration compressor 5 can use the structure of common split-type air conditioner, can also directly use its repacking, and the utility model does not have specific (special) requirements.
Air intake cooling coil 9 best level in three stream heat exchangers, 6 heat exchanging chambers 7 of the present utility model are placed and are made conduit axis in a horizontal plane.When air intake humidity was high, some moisture content wherein just may condense in cooling coil 9, and such structure makes the moisture content that condenses be brought in the dehumidifying chamber 8 by the air intake air-flow easily and discharges.Air intake cooling coil 9 and air intake heat(ing) coil 10 can be arranged in parallel, and air exhaust passage is arranged between the two, and both are directly contacted, and connect with heat-transfer metal, directly carry out heat exchange.Air intake heat(ing) coil 10 can be shorter than air intake cooling coil 9.
Air intake blower fan 1 and air draft blower fan 2 that the utility model uses can use common centrifugal fan, also can use common axial fan, and the utility model does not have specific (special) requirements.Three terminal device can use as the numerical control three terminal device of number of patent application as CN91101413.6, also can use as the numerical control three terminal device of the patent No. as CN91200002.
Refrigeration and heat radiator 3 in the utility model can be positioned over the outer exhaust outlet place of building, and the row's of use mouth is strengthened cooling effect to its cooling.
In the utility model, standard industrial control 17 can be selected the I/O 32 of U.S. ME company (MECHATRONICEQUIPMENT INC.) for use, or the PB16AH of U.S. OPTO 22 companies.Central control computer 18 can be selected the LC4 controller of U.S. OPTO 22 companies for use, also can select the PCS-1 industrial process control work station of U.S. ME company for use, can also select common PC computer for use.Measure AD3 or similar A/D modular converter that adaptation module 19,20,21,22 and 23 can adopt OPTO 22 companies.
