Common ground as all embodiments of the above or following described method for operation processing equipment be the first temperature signal T1 of detecting or monitoring more than the first temperature levels TL1 after, cooling-air blower 24 is started to remove heat from heat pump 4.The the first temperature signal T1 detected can be the combination temp signal of temperature signal receiving or can be two temperature sensors 28,29 from the first or second temperature sensor 28,29.Such as, control unit 30 is adapted to the mean value of the temperature signal of calculating first and second temperature sensor 28,29 to obtain (first) temperature signal T1 for determining whether exceeded the first temperature levels TL1.Only when the second monitored temperature signal T2 has exceeded predetermined second temperature levels TL2, just by compressor (target) rotating speed or compressor (target) power reduction.
Above or the source of the following described temperature signal of monitoring can from the second temperature signal T2 more than the second temperature levels TL2 making detection second sensor 29 for the first temperature signal T1 activating air-blaster 24 into such as detecting first sensor 28.That is, the temperature signal for determining whether to exceed temperature levels can be selected from the first or second sensor 28,29 or can be as above from the combination of the temperature signal of two sensors 28,29.
For all embodiments, for determining that the source of the temperature signal of monitoring whether exceeding temperature levels can be identical for each temperature levels or can change according to the temperature levels of correspondence or threshold value.That is, for the decision of each temperature levels, the temperature signal of the first or second sensor 28,29 can be used or use the combination from the temperature signal of temperature sensor 28,29.Alternatively, provide only a temperature sensor, such as, sensor 28, and only temperature signal is used to determine whether to exceed temperature levels or whether temperature signal drops to lower than temperature levels.For the clarity described below of exemplary embodiment of the present invention, only to all temperature signals of monitoring for determining whether to exceed corresponding temperature levels TL1..TL4, (or vice versa, whether signal is lower than temperature levels) employ a reference symbol ' Ti ', remember that corresponding temperature signal can be identical for each temperature levels decision or can be change according to the temperature levels of correspondence as mentioned above.Namely, for each decision relevant with such as above or following described temperature levels, the temperature signal Ti monitored of correspondence can be the signal of the first temperature sensor 28, second temperature sensor 29 or can be the combination temp signal of two sensors 28,29.
(if the first and/or second temperature sensor 28,29) although detected by temperature signal Ti continue to rise to higher than the 3rd temperature levels TL3-compressor rotary speed/power reduction and air-blaster be activated-, compressor 14 is with predetermined minimum speed (minimum rpm) operation, and this rotating speed is the predetermined minimum speed of compressor 14 still effectively work.If the temperature signal Ti detected rises to higher than the 4th temperature levels TL4, then compressor 14 is shut down in case stop loss the parts of bad heat pump.
According to the method for operating heat pump drier 2, there is provided is all in drying process process, the reduction of compressor rotary speed/power or compressor shutdown are minimized, and are activation cooling-air blowers 24 as the first step being used for removing heat from heat pump 4 particularly.Repeatedly the reducing and compressor 14 is shut down of compressor rotary speed/power makes the duration of drying program increase, and this is due to from there being clothing to be dried to remove the moisture needs more time.That is, along with the duration of drying process is minimized, the operating characteristics as above and following described drying machine 2 is improved.
Following power and kinemagraph schematically show the control to the compressor 14 according to some exemplary embodiments.Based on the power of real process data and kinemagraph or curve more complicated, but the schematic chart as shown in Fig. 3 to Fig. 6 clearly show that concept of the present invention and can be considered to the agenda of closely compressor rotary speed and power.
Fig. 3 show schematically show according to the first embodiment with the chart of the compressor rotary speed of detected temperature correlation.As described above, the temperature detected can be the combination receiving or can be temperature signal from two sensors 28,29 from the first or second temperature sensor 28,29, particularly according to the temperature levels of correspondence.
During the normal of heat pump 4 or the mode of operation of wishing, compressor 14 operates with predeterminated target rotating speed (target rpm).When monitored (first) temperature signal Ti (such as, the refrigerant temperature at compressor outlet place) when being increased to more than first temperature levels TL1 or threshold temperature, cooling-air blower 24 is activated so that from compressor 14 (namely, from heat pump) remove excessive heat, compressor rotary speed remains on rotating speed of target simultaneously.For example, Fig. 6 shows and makes fan activate (startup)/deexcitation (shutdown) around TL1 or its.
Although if the temperature signal Ti that air blast 24 is activated monitored is still more than the second temperature levels TL2, then compressor rotary speed is reduced to predetermined minimum value (minimum rpm), at this predetermined minimum value, compressor 14 still effectively works.During compressor rotary speed reduces, cooling-air blower 24 operates to remove excessive heat.
When detected temperature signal Ti exceedes last temperature levels TL4 or threshold value, compressor 14 is shut down.If temperature signal Ti drops to lower than temperature levels TL4, compressor 14 is activated and operates with minimum speed value (minimum rpm).When temperature signal Ti drops to lower than the second temperature levels TL2, compressor 14 operates with its rotating speed of target again.If final temperature signal Ti drops to lower than the first temperature levels TL2, then cooling-air blower 24 is shut down.
Fig. 4 show schematic presentation according to the second embodiment with the chart of the compressor rotary speed of temperature correlation.As above about described by Fig. 3, during the normal of heat pump 4 or the mode of operation of wishing, compressor 14 is with predeterminated target rotational speed operation.As mentioned above, when more than the first temperature levels TL1, cooling-air blower 24 is activated.Formed with the embodiment of above Fig. 3 and contrast, when reaching the second temperature levels TL2, compressor rotary speed is not be reduced to minimum speed value (minimum rpm) immediately.In temperature range II (that is, second and the 3rd between temperature levels TL2, TL3), compressor rotary speed is reduced to minimum speed linearly from rotating speed of target.When more than the 3rd temperature levels TL3, compressor 14 is with minimum speed Value Operations (scope III).When temperature signal Ti is more than the 4th temperature levels TL4, for security reasons, compressor 14 is shut down.In the present embodiment, compressor 14 is that Negotiation speed controls.Alternatively, in a similar fashion, compressor 14 can be controlled by power (description).
Fig. 5 show schematically show according to the 3rd embodiment with the chart of the compressor rotary speed of temperature correlation.Formed with the embodiment of the rotating speed target control in whole temperature range illustrated in fig. 4 and contrast, Fig. 5 shows the combination that power target controls (scope I) and rotating speed target control (scope II, III).
In the control diagram of Fig. 5 (and formed with the embodiment of above Fig. 3 and Fig. 4 contrast), control lower than applying power target to compressor 14 during the second temperature levels TL2, that is, compressor in temperature range I with constant power operation.When dry cycle starts, compressor horsepower is controlled; predetermined power value is supplied to compressor 14, and this predetermined power value contributes to increasing refrigerant pressure in the refrigerant loop branch between compressor 14 and expansion gear 16 with the working condition reaching as far as possible rapidly the normal of heat pump 4 or wish.As shown in Figure 5, during compressor horsepower target control, because along with the increase of refrigerant temperature and pressure, so compressor rotary speed reduces.Along with refrigerant pressure increases, for compression work consumes more motor power section and therefore rotary speed reduction.
When monitored temperature signal Ti is more than the second temperature levels TL2, as above about as described in Fig. 4, rotating speed target control is applied to compressor 14.Maintenance activates until the temperature Ti monitored drops to lower than the second temperature levels TL2 by rotating speed target control.Then, compressor 14 controls to operate according to power target as above again.
Fig. 6 shows the chart of schematic presentation according to compressor rotary speed, compressor horsepower and the cooling-air blower relevant to detected temperature Ti of the 4th embodiment.Unless otherwise mentioned, the present embodiment corresponds to the embodiment of Fig. 5.
As mentioned above, when monitored temperature signal Ti is more than the first temperature levels TL1, cooling-air blower 24 starts to be opened and keeps activating.When the first detected temperature signal Ti drops to TL1' horizontal in closing temperature (it is lower than the first temperature levels TL1), air blast 24 is shut down.That is, ensure that cooling-air blower 24 is shut down in energy efficiency temperature level.In temperature range I, depict power target and control, that is, compressor 14 is with constant power operation, and as mentioned above, compressor rotary speed reduces along with the increase of temperature.
In temperature range I, that is, to the temperature range of the second temperature levels TL2 on, compressor 14 is as above to operate about the target power described in Fig. 5.In temperature range II and III, implement rotating speed target control as mentioned above.When temperature signal Ti is more than the second temperature levels TL2, compressor rotary speed reduces linearly along with the rising of temperature signal Ti.Along with the reduction of compressor rotary speed, compressor power also reduces.
When temperature signal Ti is more than the 3rd temperature levels TL3, compressor 14 operates, until temperature signal Ti meets or exceeds the 4th temperature levels TL4 with minimum speed.Then, compressor 14 is shut down, until the temperature signal Ti detected drops to lower than the horizontal TL4' of start-up temperature, this start-up temperature level is lower than the 4th temperature levels TL4.Therefore, ensure that compressor 14 is in the upper startup of energy efficiency temperature level (TL4').
Lower than temperature levels TL4, compressor 14 operates, until the temperature signal Ti monitored drops to lower than the 3rd temperature levels TL3 with constant rotational speed (minimum rpm) again.In temperature range II, compressor rotary speed increases linearly along with the reduction of temperature, until temperature signal Ti is lower than the second temperature levels TL2.Then, compressor reducer controls to change back to power target as above from rotating speed target control and controls, that is, in temperature range I, compressor 14 operates with target power again.When institute detected temperatures signal Ti drops to TL1' horizontal in shutdown temperature, cooling air blower 24 is shut down, and compressor operates with target power.
As indicated in figure 6, temperature lag can be provided for starting blower motor 34 at higher temperature TL1 and making it shut down at lower temperature TL1'.Alternatively or in addition, compressor security deactivation is set on higher temperature hysteresis TL4, the compressor and under high-temperature situation III activates and is arranged on lower temperature hysteresis TL4'.In both cases, avoid and make blower motor 34 and compressor electric motor 14 for good and all start and shut down.
