Definitions

  • the invention relates to a condensation dryer with a heat pump and detection of an impermissible operating state and a preferred method for its operation.
  • process air In a condensation dryer air (so-called process air) is passed through a fan via a heater in a wet laundry containing drum as a drying chamber. The hot air absorbs moisture from the laundry to be dried. After passage through the drum, the then moist process air is passed into a heat exchanger, which is usually preceded by a lint filter.
  • a heat exchanger e.g., air-to-air heat exchanger or heat sink of a heat pump
  • the moist process air is cooled so that the water contained in the wet process air condenses.
  • the condensed water is then generally collected in a suitable container and the cooled and dried air is returned to the heater (which may be the heat source of a heat pump, if desired) and then to the drum.
  • this drying process is very energy-intensive, since the cooling air flow heated in the heat exchanger during the cooling of the process air can be energetically lost to the process.
  • a heat pump By using a heat pump, this energy loss can be significantly reduced.
  • the cooling of the warm, laden with moisture process air substantially in a heat sink of the heat pump, where the process air withdrawn heat, for example, used to evaporate a circulating in the heat pump refrigerant.
  • the heat absorbed in the heat sink is transported within the heat pump to the heat source and there again - optionally at opposite the temperature at the heat sink elevated temperature - discharged again.
  • a heat pump with a refrigerant acts as a heat transport means, wherein the refrigerant is evaporated in the heat sink and liquefied in the heat source, the vaporized gaseous refrigerant passes through a compressor to the heat source, which can be referred to as a condenser, where due to the condensation of the gaseous refrigerant heat released which is used to heat the process air before entering the drum.
  • the liquefied refrigerant eventually flows through a throttle back to the evaporator; the throttle is used to reduce the internal pressure in the refrigerant, so that it can evaporate in the evaporator with renewed absorption of heat.
  • the heat pump which is thus operated with a circulating refrigerant, is also known as a "compressor heat pump". Other types of heat pump are also known.
  • the DE 44 09 607 A1 describes a condensation dryer with a closed process air circuit and a heat pump device with a refrigerant circuit in which refrigerant circulates in a line system with an evaporator, a compressor, a condenser and a throttle, wherein at least one device of the refrigerant circuit, a device for cooling the refrigerant is arranged.
  • a measuring device for detecting the refrigerant temperature or the refrigerant pressure is arranged in the refrigerant circuit and an evaluation circuit controls the pump device, the cooling air blower, the actuator of the supply air or exhaust air flap or the speed of the compressor motor in dependence on the values detected by the measuring device.
  • the WO 2008/086933 A1 discloses a condensation dryer with a drying chamber, a process air circuit in which a heater for heating the process air and the heated process air can be guided by means of a blower over the objects to be dried, an air-to-air heat exchanger and a heat pump cycle with an evaporator, a Compressor and a condenser.
  • the heat pump circuit is located between condenser and evaporator an additional heat exchanger which is operatively coupled to the air-to-air heat exchanger.
  • the temperature of the refrigerant of the heat pump, in particular in the condenser is kept within the permissible range via the control of heat pump and additional heat exchanger.
  • temperature sensors are used to control the temperature of refrigerant or heat pump and the temperature of the process air in the heat pump circuit and / or in the process air circuit.
  • the EP 1 884 586 A1 discloses a clothes dryer with a heat pump circuit for guiding a medium through a condenser, a throttle body, an evaporator and a compressor back to the condenser, wherein the process air can be heated with the condenser and the process air can be cooled with the evaporator, wherein in the heat pump circuit an additional heat exchanger for withdrawing Heat from the heat pump cycle is arranged.
  • the additional heat exchanger is disposed between the condenser and the throttle body.
  • the clothes dryer has a fan for cooling the auxiliary heat exchanger with ambient air and the fan is controlled depending on a temperature in the process cycle and / or in the heat pump cycle.
  • the fan is controlled, for example, depending on a temperature T1 of the medium between the additional heat exchanger and the throttle body, wherein a power of the fan is particularly increased depending on how much the temperature T1 is above a reference temperature T0.
  • the DE 197 28 197 A1 discloses a method for detecting improper operating conditions in a tumble dryer and a corresponding tumble dryer. With the method, it should be possible to separately or collectively detect different operating conditions of too high temperature, which originate from different areas.
  • the temperature is detected periodically in the supply air above a Zu Kunststoffdorfung and before the laundry drum, formed of two consecutively detected values, a difference value or gradient, this difference value (gradient) compared with a predetermined difference value (gradient), wherein, if the newly formed difference value is absolutely greater is the predetermined difference value, a count is incremented by one step, that count is compared to a predetermined count, and if the current count is greater than the predetermined count, the heater of the clothes dryer is turned off and / or an operating status indicator is activated.
  • a compressor heat pump usually works optimally in certain temperature ranges in the evaporator and in the condenser.
  • the problem with the use of a compressor heat pump in the condenser dryer is the usually high temperature in the condenser, which can lead to process-related that the refrigerant can no longer or no longer be completely liquefied; then the compressor must be turned off and / or a significantly deteriorated effect of the heat pump can be accepted. This problem is even greater if the compressor is supported by additional heating in the process air circuit in order to achieve faster heating of the process air and thus shorter drying times. Moreover, contamination of the airways may interfere with the circulating process air. This can also lead to an increase in the temperature of the refrigerant. Such operating conditions can lead to impairment of the heat pump or other parts of the dryer and are therefore inadmissible.
  • an impermissible operating state for example a reduced circulation of the process air (air power reduction) is determined by detecting a temperature in the process air stream above a heater for the process air and in front of the drying chamber at regular intervals and in each case from two consecutively detected values a difference value is formed, which corresponds to a temporal gradient.
