Definitions

  • the invention relates to a dryer having at least one drying assembly comprising at least one air opening allowing air to be transferred into the drying chamber for moistening in order to remove at least part of the moisture from the textile product, and at least one vent through which the moistened air in the said drying chamber is passed.
  • Tumble dryers have become one of the indispensable elements in both domestic and industrial use.
  • the working principle of the dryers is basically based on delivering hot air to the laundry placed in a drying chamber. The hot air dries and dehumidifies the laundry.
  • the air sucked from the environment by the fan-snail system is first sent to the heaters. With the help of the heater, the air whose temperature rises is sent to the drum and dehumidifies the laundry.
  • This moist air is first passed through the filter and sent to the environment with the help of a vent or to the outside of the room with the help of an additional vent. In cases where it is not possible to send the moist air coming out of the vent out of the room, the hot and moist air causes the moisture and temperature of the room to increase.
  • the air pumped into the environment by the machine when the air pumped into the environment by the machine is examined, the air that changes depending on the decrease in the moisture of the laundry, but where the relative humidity is 100%, especially in the first cycles, is delivered to the environment.
  • the air temperatures coming out of the vent can reach 50 °C in the middle of the cycle.
  • the comfort level in the room decreases.
  • the hot air thrown out means that some energy is thrown out. This negatively affects the efficiency of the system.
