Definitions

  • the invention relates to an arrangement and a method for air management of a room.
  • Air pollutants can be one or more of particle pollutants, gas pollutants and microorganisms.
  • HVAC Heating, Ventilation and Air Conditioning system
  • HVAC systems are not capable of performing filtration of all particles to a sufficient extent, wherein the systems are particularly not effective in removing relatively small particles from the input air.
  • HVAC systems are not capable of removing various gas pollutants such as formaldehyde and other VOCs (volatile organic compounds) from the indoor air, because the filters used in those systems are not suitable for doing so.
  • Another shortcoming of HVAC systems is that the systems consume a lot of energy, especially when the systems are continually switched on for maintaining the air quality, which is often the case in practice.
  • stand-alone air purifiers In the field of managing quality of indoor air, in order to complement the shortcomings of HVAC systems, stand-alone air purifiers have been developed.
  • An example of such an air purifier is known from WO 2012/066453 A1.
  • Stand-alone air purifiers are to be placed inside a room and are very useful to people living in highly polluted cities, as they help a great deal in removing various kinds of pollution from indoor air. Operation of a stand-alone air purifier requires considerably less power than operation of a HVAC system.
  • a stand-alone air purifier is capable of removing both large particles and small particles from the air, due to the fact that the fan which is part of the air purifier and which serves for forcing air to flow through the air purifier is powerful enough to enable the application of a high efficiency filter in the air purifier.
  • Another advantage of the stand-alone air purifier resides in the fact that the air purifier can be used for removing indoor gas pollutants.
  • a stand-alone air purifier is not capable of removing carbon dioxide from air. Therefore, a room in which such an air purifier is present needs to be ventilated, at least from time to time. In general, assuming that the room has windows, ventilation can be realized by opening a window, but this may worsen the indoor air quality if the outdoor quality is very bad. It cannot be left up to a user to determine the right time to open the window and to determine an appropriate duration of the ventilation action.
  • JPH11201511 It is known from JPH11201511 to provide an air cleaning system comprising a a blower for circulating and filtering air in a room and a ventilator for introducing outside air into the room.

  • the control system is adapted to process air quality data relating to both the inside environment of the room and the outside environment
  • indications like “inside environment” and “indoor” should be understood such as to be related to the air which is present inside the room
  • indications like “outside environment” and “outdoor” should be understood such as to be related to the air which is present outside the room and which can be let in to the room by means of the ventilating means, which in most cases is air from the open air which is present outside the building of which the room is part.
  • the invention provides a way of avoiding a situation in which the carbon dioxide level in the room can become dangerously high as a result of long term operation of the stand-alone air purifier, avoiding a situation in which energy is wasted, and avoiding a situation in which air cleaning only takes place at a low rate.
  • the arrangement according to the invention comprises three main components, namely ventilating means, a stand-alone air purifier and a control system.
  • the ventilating means may comprise a bi-directional fan, a set of fans, wherein one fan serves for discharging air from the room and another fan serves for supplying air to the room, automatically controlled windows or any other mechanical structure which may have a function in exchanging air between the inside environment of the room and the outside environment of the room, for discharging dirty air from the room and introducing fresh air to the room.
  • the main function of the stand-alone air purifier is cleaning dirty indoor air.
  • the air purifier may be adapted to remove at least one of gas pollutants and particle pollutants from the indoor air. Ideally, the air flow of at least one of the ventilating means and the air purifier can be adjusted.
  • Control of the ventilating means and the air purifier includes determining when the ventilating means and the air purifier should be switched on and off, and may also include setting a rate of the air flow, for example.
  • the control system is adapted to use both air quality data relating to at least one of the inside environment of the room and the outside environment of the room.
  • the air quality data may be collected from suitable sensing means and/or a general data source, wherein the latter is especially applicable to air quality data relating to the outside environment of the room.
  • the data may be obtained through a data collector, which may be a sensor situated at any appropriate position inside the room and/or a website data collector.
  • a suitable controller may be applied, which is situated on or near the ventilating means, wherein the controller is arranged to receive information from a sensor situated on or near the ventilating means for detecting carbon dioxide, particles or gas pollutants, and also from a data collector which is adapted to collect data from an official website regarding actual outdoor air quality. Communication between the controller and at least one of the ventilating means and the air purifier may take place in a wireless fashion.
  • a suitable controller is a controller which is adapted to follow certain algorithms which are aimed at realizing operation of the ventilating means and the air purifier in such a way that the indoor air quality is always at its best under the given circumstances and waste of energy is avoided.

If the outdoor air quality is good enough, it is no problem to operate either one of the ventilating means and the air purifier. However, if the outdoor air quality is bad, an optimum has to be found in respect of two conflicting requirements, namely the requirement to have clean indoor air and the requirement to prevent the carbon dioxide level of the indoor air from rising to an unacceptable value.

  • the ventilator 10 After the ventilator 10 has been operated during a certain time which is appropriate in view of room size and number of people present in the room 100 , the ventilator 10 will be put to the inactive condition and the air purifier 20 will automatically be switched on.
  • the air purifier 20 will be switched off and the ventilator 10 will be switched on again, which is advantageous for bringing the carbon dioxide level in the room 100 down, which has become higher and higher in the meantime due to the presence of people in the room 100 and the room 100 being kept closed.
  • the arrangement 1 for air management of the room 100 is a flow meter assisted arrangement.
  • a flow meter can be used for measuring the ventilated air amount and for assisting the control system 30 in determining the time interval of alternating the operation of the ventilator 10 and the air purifier 20 .
  • the ventilator 10 After the air purifier 20 has continuously been in the active status for one hour, while the room 100 has been kept closed, the ventilator 10 will be put to the active status in order to reduce the carbon dioxide level to an acceptable value.
  • the flow meter on the ventilator 10 is used for determining when the ventilation can be stopped, while the flow rate is adjustable according to the room size. In general, it will be practical and sufficient to exchange the air in the inside environment 102 of the room 100 with air from the outside environment 103 of the room 100 once per hour.
  • the fact that the flow rate of at least one of the ventilating means and the air purifier may be adjustable, wherein the control system is adapted to set the flow rate of the at least one of the ventilating means and the air purifier, is not only applicable to the main concept of the invention as reflected in claim 1 , but may very well be combined with one or more further aspects of the invention. Any reference signs in the claims should not be construed as limiting the scope of the invention.
