Existing one " anti-condensation mechanism " by name, the patent No. is 03221410.3 utility model patent, a kind of mechanism that avoids in refrigerating-chamber door generation dewfall on glass phenomenon is disclosed, comprise an inlet scoop, this inlet scoop comprises left and right side plate, base plate, header board, the base portion of left and right side plate is fitted with the condenser of cabinet is vertical, and the refrigerating chamber base plate of the upper edge of left and right side plate and cabinet fits, base plate is solid mutually with the bottom of left and right side plate, the front portion of header board and left and right side plate is solid mutually, and its preceding bead is licked mutually with the showcase bottom panel and closed; One motor places in the described inlet scoop; One fan is fixed on the motor shaft of motor; Some wind-tunnel are opened in the upper edge of showcase bottom panel, correspond respectively to the bottom of refrigerating-chamber door glass and slightly are positioned at the preceding bead of the described header board of its below.It simple in structure, easy to operate, flexible, but be confined to the solution of the glass anti-condensation problem of refrigerating-chamber door, inapplicable for the roof anti-condensation problem in large-sized workshop, warehouse etc.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of reasonable in design, simple in structure and can effectively solve the device of the roof condensation trouble of buildings (hereinafter to be referred as building) such as large-sized workshop, warehouse, venue at the above-mentioned state of the art.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this roof anti-condensation device includes pressure fan, pipeline, nozzle, axial flow blower, heat exchanger, indoor and outdoor humiture checkout gear, control system.It is characterized in that: building is divided into several zones, each zone outside the building portion is established one in pressure fan, by pipeline, heat exchanger and nozzle hot blast is sprayed onto on the interior of building roof, axial flow blower is located on the building wall of corresponding region, clammy air in the factory building is taken away, indoor dew point checkout gear and outdoor temperature humidity detector are established in each zone, testing result result sends to control system, thereby judges whether the open and close and the air quantity of dewfall control blower fan and axial flow blower by calculating.
As improvement, building is divided into several regions by the 800-1500 square meter, and as a zone, it is the 3-8 platform that 1 in pressure fan, axial flow blower quantity are established in each zone, establish indoor dew point detector and outdoor temperature humidity detector, each 1 cover of control system.
Improve, pressure fan is fixed on the outdoor basis, ground again, and airduct is fixed on the metope, to reduce noise effect.Heat exchanger is installed in the air supply duct middle part, and interior logical saturated vapor heats the wind that passes through.Nozzle and airduct end link to each other, enter in the building its direction towards the roof.
Improve, axial flow blower is arranged on the metope apart from the position of ground 5-10 rice again, and the air draft direction is outside.
As further improvement, the dew point detector is known with temperature, humidity value carries out the device of computing output dew point value, be arranged on the interior position of building apart from roof 1-2 rice, establish the humiture detector on the outdoor roof, outdoor temperature and indoor dew point transfer of data compare to control system, when outdoor temperature is higher than indoor dew point can dewfall more than 5 ℃ the time, pressure fan and axial flow blower do not start, possible dewfall when outdoor temperature is higher than indoor dew point 2-5 ℃, control pressure fan air quantity 50%, axial flow blower 50% quantity (rounding the platform number) running, when being higher than indoor dew point, outdoor temperature can produce dewfall below 2 ℃ the time, control pressure fan air quantity 100%, axial flow blower all turns round.
Compared with prior art, advantage of the present utility model is: the principle of utilizing limit blowing hot-air limit air draught, to heating and take away containing humid air in the building roof, can solve building roof condensation trouble well, can not increase indoor air pressure simultaneously, not change personnel's comfort level.Simultaneously, unlatching and air quantity that humiture, dew point checkout gear and automatic control system can be controlled are in case of necessity regulated, and can play energy-conserving action, and be fine through practical application effect, be worthy to be popularized.
