Definitions

  • the present invention relates to a ventilation system.
  • the ventilation system is largely classified into a decentralized ventilation system and a central ventilation system.
  • the decentralized ventilation system is a system in which a ventilator is installed in individual homes to be directly supply the external air and directly discharge the internal air to the outside, in the homes.
  • the central ventilation system is a system in a ventilator is installed at each floor or a predetermined position in a building, not in individual homes, to supply the external air to each home through a center duct connected with the ventilator and discharge the internal air of each home to the outside through the center duct and the ventilator.
  • the ventilation performance of the decentralized ventilation system is deteriorated in accordance with external conditions.
  • An object of the ventilator is to supply constant air flow set by a user to a home.
  • the wind velocity gradually increases with reduction of frictional effect, such that stronger wind blows at the upper portion than the lower portion of a building. That is, external air is introduced at large pressure in the ventilator, such that it is difficult to supply constant air flow.
  • the ventilation performance is also deteriorated in accordance with changes in direction of wind around the ventilator. For example, when wind does not blow around the ventilator, it needs to operate a fan at high speed to supply the air flow set by a user, thereby causing unnecessary energy loss.
  • the decentralized ventilation system has a problem that it is considerably affected by changes in the environment outside a building, because it operates while being directly exposed to the external air.
  • the ventilator provided at the center since the ventilator provided at the center has to cope with ventilation load for each floor or throughout a building, there is a problem that large area and volume are required for devices and the system configuration. Further, the more the number of floors, the longer the flow channel of air discharged from the ventilator becomes, such that static pressure loss is generated by friction of the flow channel. Therefore, there is a problem that it is difficult to supply sufficient air flow to the homes at the high floors of the building. More central ventilation fans are operated to complement the problem, but in this case, there is a problem that air flow is excessively supplied to the homes at the lower floors. Further, it is difficult to supply sufficient air flow to the homes at the high floors, when the homes at the low floors consume large air flow. That is, there is a problem that it is difficult to supply equal air flow to all the homes.
  • a ventilation system for a high-rise building includes: one or more ventilators which are provided for each floor within a building; a supply duct connected to the ventilator to introduce external air; an exhaust duct connected to the ventilator to exhaust internal air; a center duct which is provided in the building and longitudinally extends through a plurality of floors; and a blowing unit that is provided at one side of the center duct and forcibly blows the air in the center duct, wherein one of the supply duct and the exhaust duct is connected to the center duct and the other extends outside the building through the outer wall of the building.
  • a ventilation system of an embodiment of the present invention it is possible to supply constant air flow to each floor or home, regardless of changes in environment outside a building, by connecting a ventilator to a center duct that sucks external air and supplies it to each floor or home, or sucks internal air of each floor of home and discharges it to the outside the building.

  • a filter (not shown) that removes foreign substances in the air may be attached to the side close to the intakes 231 and 235 of the heat exchange element 25 .
  • Heat is exchanged through the heat exchange plates while the internal air and the external air pass across each other through the heat exchange element 25 , such that the inside temperature does not rapidly increase or decrease.
  • FIG. 3 is a view showing a blowing unit that sucks external air that is supplied to the center duct of FIG. 1 .

  • the external air supplied in the ventilator 20 exchanges heat with the internal air while passing through the heat exchange element 25 , and then is supplied to the inside of the home 5 through the discharge duct 31 .

  • the stack effect is the biggest factor among them to affect the supply of constant air volume.
  • the stack effect is brought about by the difference of the air density between the inside and the outside of a building.
  • the pressure inside the building is relatively lower than that out side the building. Therefore, the air outside the building is introduced into the inside of the building, thus the introduced external air vertically goes up to be discharged outside of the building.
  • the internal air of the building is introduced into the external air supplying passage of the ventilation system, especially the ventilator, thus precludes the outside to be introduced into the inside of the building.
  • the load of the air supply blowing unit 26 is increased, whereas the load of the air exhaust blowing unit 27 is decreased. In summer, the circumstance appose to that in winter will happen.
  • the phase current applied to a fan motor of the air supply blowing unit 26 is changed.
  • the load of the air supply blowing unit 26 is increased by the stack effect, thus the phase current applied to the fan motor is increased. It means decreasing of the amount of air supplied to the inside of the building, specifically to the inside of the home by the air supply blowing unit 26 that the phase current applied to the fan motor of the air supply blowing unit is increased.
  • the controller of the ventilator 20 is configured to detect the change of the phase current supplied to the fan motor of the air supply blowing unit 26 , and control the inverter of the fan motor such that the amount of the current supplied to the fan motor become increased.

Therefore, the controller, on the basis of the table, evaluates the change of the RPM of the fan motor according to the change of the phase current detected by a detecting element(not shown) and evaluates the amount of the current to be supplied to the fan motor based on the evaluated change of the RPM. Then, the controller controls such that the fan of the air supply blowing unit 26 rotates in accordance with the RPM calculated through the process described above. Namely, by controlling the inverter of the fan motor such that the fan of the air supply blowing unit 26 rotates to the calculated RPM, the amount of the current supplied to the fan motor is increased. Then, the air volume supplied to the inside of the home can be maintained constant, even if the indoor circumstance is changed.
  • the indoor and outdoor circumstances should be considered together, in order to maintain the air volume supplied to the inside of the home constant.
