Definitions

  • the present invention refers to control systems for the atmosphere conditioning of a pressurized room, namely for maintaining a stable pressure in a range of optimal values and for ensuring purified air in the respective room, as well as methods of implementation and use of these systems.
  • the invention pertains to the fields of environment control of closed spaces and of health devices, specifically to the domain of air conditioners.
  • the disclosed invention is a system able to purify the air, send it to a room, and control the absolute pressure in that room by adding or removing air from the room, according to the case.
  • the disclosed system may control the humidity and/or temperature of the circulated air.
  • the system may be taking into account the pressure difference in the room for controlling the air flow.
  • the disclosed system may be provided with means for remote communication and control and with means for storing the data on its operation.
  • the purpose of the system described by the invention is to create an atmospheric ambience for subjects in a room such that the room atmosphere to conform to findings relating the air pressure and humidity with the quality of life for people with some specific health conditions.
  • Such conditions may include arthritis, asthma, and migraines related to the atmospheric conditions.
  • the invention may improve the quality of life of some of the people presenting meteoropathies.
  • meteoropaths are people negatively affected by weather conditions.
  • Meteoropathies may include asthma, increase in osteoarthritis joint pain, and psychiatric conditions.
  • Other studies have shown that weather conditions, especially air pressure variations, may increase susceptibility of acute myocardial infarction and strokes. These conditions were related to clime and weather conditions in several studies, but not for all subjects and in a variable degree for those affected.
  • the disclosed invention creates the first device to maintain a specified pressure in a typical room for meteopaths, moreover maintaining a clean atmosphere in the room.
  • the system is able to create larger or smaller pressure than in the environment, according to the desire or needs of the user, or according to medical advice. Further, the system may dehumidify or increase the humidity of the air and cool or heat the air sent into the room.
  • the invention may improve the quality of life for those sensitive to weather conditions (the medical term is meteoropaths).
  • meteoropaths are people negatively affected by weather conditions. Are you one of them? Meteoropathies may include asthma, increase in osteoarthritis joint pain, and psychiatric conditions. Some psychiatric disorders were also related to clime and weather conditions in several studies. Other studies have shown that weather conditions, especially air pressure variations, may increase susceptibility of acute myocardial infarction and strokes.
  • Standard air pressure is 101.3 kPa at 0 m altitude and decrease to about 90 kPa at 1000 m.
  • the atmospheric pressure at the sea level varies significantly according to meteorologic conditions. Normal barometric pressures range between 29.8- and 30.2-inch Hg; pressure over 30.20 inch Hg are considered high; low pressures are considered to be below 29.8 inch Hg and may occur during warm air conditions and rainstorms. So, atmospheric pressure varies between 28 and 31 inches of mercury, that is 95 to 105 kPa, or a variation from -6 kPa to +4 kPa (sea level). It is the pressure difference the system should be able to compensate.
  • the disclosed system includes one or several air filters ( 1 ) of high efficiency, for example HEPA or ULPA filters, for removing particulate contaminants from the air.
  • the system may include germs killing devices ( 2 ), for example ultra-violet (UV) lamps or LEDs, or ionizing devices.
  • the purified air is driven by an air pump ( 3 ) and conducted through the clean compartment of the system directly to the room, or through a tube or conduct ( 4 ) to the room ( 5 ) with controlled atmosphere.
  • the system further includes an absolute pressure sensor ( 6 ) that connects to the room through a tube ( 7 ), where the sensor measures the absolute pressure in the room ( 5 ).
  • the system may include a differential pressure sensor ( 8 ) that measures the pressure difference between the controlled room (5) and an external space.
  • the system may include supplementary sensors for measuring the air flow and the quality of the air sent to the controlled room ( 5 ).
  • the quality of the air may be determined wit a sensor of CO2 and with sensors for particulate contaminants.
  • the control system ( 9 ) receives data from all the sensors and receives the preset desirable interval of pressure in the room with conditioned atmosphere from manual or remote controls. Based on the data and presetting, the controller adjusts the air flow through the air pump ( 3 ).
  • the airflow may be determined indirectly knowing the two pressures - inside and outside the room ( 5 ), or may be determined with a flow sensor ( 10 ), which also send data to the controller ( 9 ).
  • the controller may receive data from a sensor ( 11 ) for the particulate contaminants. Further, the controller may adjust the other parameters of the circulated air, such as humidity and/or temperature, using a dehumidifier (12) and a heater-cooler.
  • the preferred pressure ranges the system has to compensate is that of typical atmospheric pressure variations at sea level, that is, -5 kPa below to +5 kPa above the normal atmospheric pressure of 10 kPa.
  • the location of the user may be at various altitudes, where the normal pressure in the atmosphere has specific values, dependent on the altitude. Therefore, the system has to have the "normal limits" set for a specific altitude.
  • the system may be manufactured to be battery operated or power line operated, or both.
  • the room with the atmosphere controlled by the system has to be partially or almost totally sealed, for example with windows that do not open, as in some buildings our days, a way of refreshing the air has to be guaranteed.
  • the room is almost totally sealed, one needs to bring air inside - which has to be first purified - also letting some air outside (impurified). Therefore, a double circulation should be permitted, at least to clear the CO2 produced by the people inside during respiration.
  • the air in the room is refreshed from time to time by bringing fresh air from outside by allowing the slight increasing of the pressure in the room, then by decreasing the pressure, while maintaining all the time the pressure inside the room in the specified range.
  • a second solution is to use a pump with a motor with controlled rotation direction, where the motor can be coupled to any of two fans blowing air in opposite directions.
  • FIG. 2 A third solution is shown in Figure 2 and uses an air pump (3) blowing air in a single direction and a set of valves (13, 14,15) that configure the air duct in two different manners, one through the filter for the air flow toward the chamber, and the second through a supplementary air way not involving the filter.
  • units for reducing air humidity include a compressor to compress the refrigerant, one or several condenser coils for removing the heat from the refrigerator to the outside air, and a fan for improving the efficiency of the condensing coil.
  • the system may use such a dehumidifying device.
  • a Peltier cooling device may be used for condensing the water vapor instead of the typical compressor-condenser-fan devices.
  • a heat pump may be added to the system according to the invention, for cooling or heating the air sent to the atmosphere conditioned room.
  • the system case may be embedded in and traverse a wall, a wall-embedded furniture, or a door, with the air inlets/outlets on the two sides of the wall or door.
  • air ducts may be use to the external side of the room, or to the internal side of the room, or both. Vent covers with slits cuts may protect the air inlets and outlets.
  • Various supplementary devices can be added, such as sound and light alarms signaling the pressure is not in the set range, means for remote control, and means for communication.
  • the system may be remotely connected to weather prediction data sources and set to start regulating the pressure according to the weather predictions.
  • the system may further remotely connect to external devices such as a phone or tablet producing recordings of the operation parameters, including pressure in the controlled room, and allowing the remote control of the operation, including the setting of the operation pressure limits, humidity limits, and temperature limits.
  • the presented system is useful in advancing and improving the research on the meteopathies. It is still unclear in the current state of the art what effect the combination of factors such as air humidity and its variation, air pressure and its variation, and air temperature and its variation have in various meteopathies. For example, it is still unclear if the value of the air pressure or its variation is a factor in certain meteopathies, such as rheumatoid pain and temporary worsening of rheumatism conditions.
  • the use of the disclosed system in studies about these combined factors is seen as one of the applications targeted.
  • the flexibility of operation of the systems disclosed makes them a good research tool and, at the same time, allows users to adjust the operation to their own response to meteoropathies.
