Definitions
- the invention relates to a condensation dryer with a drying chamber for objects to be dried, a process air circuit in which the process air can be guided by means of a blower over the objects to be dried, and a heat pump circuit for alternately heating and cooling the process air.
- the invention also relates to a method of operating such a condensation dryer.
- Tumble dryers whose operation is based on the condensation of moisture vaporized by means of warm process air from the laundry - so-called condensation dryers - are very popular because they produce no exhaust air laden with moisture and no hose for dissipating this exhaust air from a building in which such a tumble dryer is set up. Condensation dryers can therefore be used in internal bathrooms or laundry rooms of larger residential complexes.
- a condensation dryer process air is passed through a fan via a heater in the wet laundry containing drum as a drying chamber.
- the hot air absorbs moisture from the laundry to be dried.
- the now moist process air is directed into a heat exchanger, which is usually preceded by a lint filter.
- the moist process air is cooled, so that the water contained in the moist process air condenses.
- the condensed water is then collected in a suitable container.
- the cooled and dried air is then returned to the heater and then to the drum.
- the heat exchanger can be easily removed for occasional cleaning of dried lint (microfibers of the laundry).
- a condensation dryer with a closed process air circuit is described, which is equipped with a heat pump.
- the heat pump is designed as a device operating according to the absorber principle whose absorber forms a third heat exchanger whose coolant flows through the primary circuit and via whose secondary circuit the process air flowing from the second heat exchanger is returned to the secondary circuit of the first heat exchanger.
- An object of the invention is therefore to provide a condensation dryer with a heat pump, which has an increased life and offers the possibility for easier cleaning.
- Preferred embodiments of the condensation dryer according to the invention are listed in the subclaims 2 to 8.
- a preferred embodiment of the method according to the invention is listed in claim 10.
- the invention thus relates to a condensation dryer with a drying chamber for objects to be dried, a process air circuit in which the process air can be guided by means of a blower on the objects to be dried, and a heat pump circuit for alternately heating and cooling the process air, in which condensation dryer between at least one secondary fluid circuit is located in the process air circuit and the heat pump circuit.
- the invention also provides a method for operating a condensation dryer with a drying chamber for objects to be dried, a process air circuit in which the process air is guided by means of a blower over the objects to be dried and thereby alternately heated and cooled by a heat pump cycle, wherein between the process air circuit and the heat pump circuit is at least one secondary fluid circuit through which heat is exchanged between the heat pump circuit and the process air.
- the secondary fluid circuit contains a secondary refrigerant which is a substance which is liquid at room temperature and normal pressure.
- the secondary refrigerant in a secondary fluid circuit at least one substance from the group consisting of water, single and multiple alcohols and glycol ethers.
- Suitable polyhydric alcohols are, for example, ethylene glycol and propylene glycol.
- Suitable glycol ethers are, for example, ethylene glycol dimethyl ether and propylene glycol dimethyl ether or the corresponding monoether.
- water is used as the secondary refrigerant.
- the heat pump preferably has an evaporator, a condenser, a compressor and a throttle.
- the compressor is generally in the flow direction of the primary refrigerant between the evaporator and the condenser.
- an expansion valve also referred to as throttle.
- the primary refrigerant used in the heat pump preferably circulates in the heat pump cycle with a turbulent flow. Turbulent flow may be adjusted by suitable design of a flow channel and / or by suitable drive means (e.g., compressor).
- the condensation dryer according to the invention contains at least one secondary fluid circuit between the heat pump and the process air circuit.
- one or two secondary fluid circuits are located between the heat pump and the process air circuit.
- the condensation dryer according to the invention has a first secondary fluid circuit and a second secondary fluid circuit.
- a secondary refrigerant which is generally different from the primary refrigerant, circulates.
- the heat pump thus gives its cooling power or heating power via a secondary refrigerant (also called “secondary fluid") in at least one secondary fluid circuit to the process air circuit of the Condensation dryer off.
- secondary refrigerant also called "secondary fluid”
- the cooling or heating power is generated centrally in a heat pump, which can be very compact in the condensation dryer according to the invention.
- the warm, moisture-laden process air is cooled in a first heat exchanger in which the process air circuit and the first secondary fluid circuit contact via a good heat-conducting wall ,
- the moisture contained in the process air condenses and is generally collected in a suitable receptacle, e.g. a bowl, collected from where it is disposed of.
- the dried, cooled process air is heated in a second heat exchanger in which the process air circuit and the second secondary fluid circuit contact via a wall which is as heat-conductive as possible .
- the heated process air is then in turn supplied to the laundry drum as a drying chamber.
- the process air can be additionally heated by an electric heater.
- the secondary refrigerant (“secondary fluid”) is most preferably water. Since this can be done almost pressure-free relative to the ambient pressure, the flowed through by the process air heat exchanger between the heat pump and the process air circuit, for example via quick-release closures (as used similarly as articles for garden irrigation) are connected to the heat pump.
- the secondary refrigerant used in the secondary fluid circuit preferably water, is generally supplied via an external inlet (water inlet).
- the condensation water obtained during the drying process is at least partly used as a secondary refrigerant.
- the temperature of the secondary refrigerant and the temperature of the primary refrigerant are generally kept within the allowable range by the control of the heat pump. If, in the condensation dryer according to the invention in the process air circuit before the entry into the drying chamber is preferably a heating, generally takes place the control of the heat pump in coordination with the control of the heater.
- the condensation dryer according to the invention has a first secondary fluid circuit and a second secondary fluid circuit, so that both heat exchangers of the heat pump are each connected to the process air circuit via a secondary fluid circuit.
- the condensation dryer according to the invention has at least one removable heat exchanger.
- the removable heat exchanger may be the first and / or the second heat exchanger.
- the first heat exchanger is preferably removable, since it tends more to contamination with lint.
- two secondary fluid circuits are located between the process air circuit and the heat pump circuit, and heat is exchanged between these between the heat pump circuit and the process air.
- the heat exchange between the heat pump circuit and the first and second secondary fluid circuit is particularly efficient when the refrigerant is moving in turbulent flow.
- the primary refrigerant in the heat pump circuit is turbulent.
- a turbulent flow can also be set in the secondary fluid circuit and / or in the process air circuit instead of a laminar one.
- the secondary fluid lines are thermally insulated except for the line sections located in the respective heat exchanger.
- process air and primary or secondary refrigerant are passed through the heat exchangers in a cross-flow or countercurrent process.
- the degree of drying of the objects to be dried in the condenser dryer decreases the energy required for drying, it is appropriate to regulate the heating accordingly, that is. As the degree of dryness progresses, their heating power is reduced to maintain a balance between the supplied and necessary drying energy. With increasing degree of drying of the objects to be dried, in particular laundry, thus a lower heating power or even an increasing cooling capacity of the heat pump is required. In particular, after a completed drying phase, the temperature in the process air circuit would rise sharply. In general, therefore, the heat pump and the heater in the condensation dryer are controlled so that a maximum allowable temperature is not exceeded in the drying chamber.
- the invention has numerous advantages.
- the long-term stability of condensation laundry dryers with a heat pump is improved due to the use of secondary fluid circuits.
- a coefficient of performance of the heat pump cycle increases, with a slight reduction in the coefficient of performance due to the at least one secondary circuit (increase in the number of heat transfers) being more than offset by the elimination of the problems with contaminated heat exchangers.
- the heat exchanger through which the process air flows can be very easily disassembled and cleaned. As a result, the performance of the heat exchanger is maintained.
- the heat pump unit can be very compact, in particular from compressor, evaporator, throttle and condenser prefabricated. After installation, only the secondary fluid lines need to be connected. This makes it much easier and automated to produce the heat pump unit. This reduces the cost of the manufacturing process and enables a higher, easier-to-control manufacturing quality.
- the placement of the heat exchangers for the process air is when using very low boiling refrigerants such. Carbon dioxide is no longer bound to narrow limits by the high-pressure lines of the refrigerant circuit.
- the secondary fluid may also dissipate the waste heat of the compressor of the heat pump to the process air of the clothes dryer. This increases the overall efficiency of the heat pump process and thus the energy balance of the entire drying process.
