  • Each heat exchanger is placed on the path of air circulation provided by one or more fans.
  • Such an evaporator comprises a body or a casing forming a tank in which is fitted, for each fan, an air intake extending substantially in a plane horizontal. The sucked air is diverted towards the two exchangers placed laterally, to then be discharged by two outlets extending substantially in a vertical plane.
  • such a container also called a drainer
  • a drainer must ensure the collection of condensates and the entry of air while providing an certain aesthetics, since such a bin generally constitutes the facade of the device. It must be considered that such characteristics must be respected, regardless of the power of the device.
  • the power of the evaporator depends the design of the exchangers with which a determined number of fans. It follows that each evaporator model of a given power requires the creation of a specific drip tray. Indeed, each model of bin has dimensions and a number of air inlets adapted to the power of the evaporator to be fitted. Difficulties appear for manufacturing, storage and the maintenance of such devices, which greatly increases their cost.
