Definitions

  • the invention relates to a device intended to maintain, in a determined volume, a living room for example, the ambient temperature relatively constant.
  • It relates more precisely to an air conditioner capable of performing at least two functions, that of heating the air when the ambient temperature tends to drop, and that of cooling it when this temperature tends to rise.
  • the heating elements may be shielded electrical resistors or semiconductor ceramic resistance resistors with a positive coefficient.
  • the present invention aims to solve this problem and relates to a device whose architecture means precisely avoids this risk.
  • a device intended to maintain a relatively constant temperature comprising a casing (10) with a reservoir (3) of liquid (33), a pump (2), a filter (1) and a fan motor (4), constituting a main circuit (A) for air circulation from the rear (AR) of the device towards the front (AV) thereof according to the arrow (F); characterized in that it further comprises a second circuit called the auxiliary circuit (B) separated from the main circuit (A) by means of a part (6) carrying a plurality of conduits (n, n1, n2 ... n n ) which pass through the filter (1) and are intended to also convey, in cooperation with the fan motor (4), the air from the rear (AR) towards the front (AV) of the device according to said arrow (F) .
  • a device consists of a casing (10) in which is placed a fan (4) responsible for creating a current of air, according to the arrow (F), from the 'rear (AR) to the front (AV) of the device.
  • the air borrows two circuits, one said to be main (A) and the other said to be secondary (B). These two circuits are separated from each other by means of a part (6) comprising a plurality of conduits (n1, n2 ... n n ).
  • the air flowing through the main circuit (A) follows the arrow (F1) by passing through a filter (1) soaked in water.
  • a pump (2) sucks the water (33) contained in an element of the casing (10) forming a water tank (3), to discharge it, via a pipe (22), into a weir (23 ) from where it flows into the filter (1).
  • This main circuit (A) then operates as an evaporative air conditioner.
  • the ambient hot air cools at the level of the filter (1) and is evacuated towards the front in the form of a flow of so-called main air (F1) cooled, humidified. This is an operation of the device known as "in cooling mode".
  • the auxiliary circuit (B) implements a part (6) comprising a plurality of conduits (n1, n2 ... n n ) passing through the filter (1).
  • Ambient air is drawn from the rear (AR) of the device towards the front (AV), along the arrow (F), through this plurality of conduits (n, n1 ... n n ).
  • the air coming from the rear (AR) passes through the plurality of conduits (n1, n2 ... n n ) of the room (6), and through the elements (5).
  • An air flow (F2) is thus formed at the front of the device. In this operating mode, this flow (F2) is said to be secondary.
  • Fins (50), which can be directly molded in the part (6) are adapted to create a pressure drop compatible with that of the filter (1). Under these conditions, the air flow passing through the main circuit (A) and the air flow passing through the conduits (n, n1 ... n n ) are balanced. It follows that the air flow from the auxiliary circuit (B) does not disturb the operation of the circuit (A) in cooling mode.
  • the plates (5) are energized and therefore heat the air passing through them.
  • a main hot air flow (F2) is therefore distributed to the front of the device.
  • the fins (50) here again play a balancing role which ensures sufficient heating power in "hot” mode, in particular when using as heating elements (5) PTC plates whose heating power increases with the air flow through them.
  • the filter (1) In this "hot" operating mode, the filter (1) is not soaked of water. At the same time, an air flow (F1) mixes with the air flow (F2). If the pump (2) is stopped, this flow (F1) is not humidified.
  • the filter (1) is supplied with water and the heating elements (5) operate.
  • a flow (F1 + F2) of humidified hot air is thus obtained at the front.
  • these conduits (n, n1 ... n n ) the air is channeled and isolated from the humid environment formed by the filter (1).
  • the heating elements (5) are protected from moisture.
  • These heating elements can be semiconductor elements with a positive coefficient resistance as described above, but they can also be shielded heating resistors for example.
  • the part (6) has five conduits (n, n1, n2, n3, n n ) held in place by a support (100) and forming a circular arc made integral with the rear grid (101) (Fig. 2) closing the casing (10) by means of lugs (66).
  • This part (6) can be produced by molding in plastic material.
  • a device finds its application in particular for air conditioning living spaces, the interior of automobiles, and generally for air conditioning any volume to be maintained at a relatively constant temperature and humidity.
