In aircondition 10, as shown in Figure 1, has control device 40.In indoor set 12, have as the detection of interior sensor 29 at the temperature sensor 29A of the inside inhaled air (the being room air) temperature of air entry 27A (Fig. 2), detect the temperature sensor 29B of the temperature of cold-producing medium in the indoor heat converter 21 and detect the humidity sensor 29C of indoor humidity of the air suction side of indoor heat converter 21.
In this control device 40, be connected with interior sensor 29, switch 30,31 and display part 33 etc. with holding wire.Aircondition 10 has the remote controller 34 of operation of air conditioner that can radio operation.In this remote controller 34, be assigned the address.Control device 40 is only just accepted the operation of this remote controller 34 when consistent with addresses distributed among the main frame 12A.In addition, on this control device 40, be connected with buzzer 35.
This control device 40 has microcomputer 41, according to the prepositioned control program of not representing among the figure in mediums such as ROM aircondition 10 is all controlled.
Operating frequency, the switching of cross valve 18 and the winding number of propeller fan 20 of the compressor 16 of these control device 40 difference control examples such as off-premises station 11.The winding number of the cross flow fan 23 of control device 40 control indoor sets 12 and the aperture of electrodynamic type expansion valve 22 in addition.By the switching to this cross valve 18, aircondition 10 is set at refrigeration (or dry) running or heating running.
Air conditioner load control as requested, the operating frequency of the compressor 16 of the heating ability of regulation when refrigerating capacity of stipulating in the time of should reaching cooling operation and heating running.Be that control device 40 control operation of air conditioner make the temperature that is reached setting by the detected indoor temperature of temperature sensor 29A.At this moment, will stop the control of compressor 16 runnings less than deviation (for example 1 ℃) timed unit 40 of regulation in the deviation of indoor temperature and design temperature.
In addition, in control device 40, have a for example storage part 42 of the rewritable fixedness internal memory of EEPROM etc.In this storage part 42, the address of storing main frame 12A.In addition, in this storage part 42, storing the abnormal information of aircondition 10 (off-premises station 11 or indoor set 12).Specifically, storing the mistake of fan electromotor 23A of cross flow fan 23 of mistake, the indoor set 12 of the interior sensor 29 of indoor set 12, the garble that off-premises station 11 and indoor set are 12 and from mistake of off-premises station 11 etc.Be control device 40 when these wrong generations, in storage part 42, these mistakes noted as abnormal information.
Mistake as interior sensor 29, for example for the resistance abnormal ascending (sensor opens circuit) of sensor 29, perhaps reducing the fault of (short circuit sensor) etc. unusually for the resistance of sensor 29, perhaps is the situation of detected temperatures abnormal ascending of the temperature sensor 29B of indoor heat converter 21.As the mistake of the fan electromotor 23A of indoor set 12, for example be situations such as the unusual or temperature anomaly of revolution.As garble, be the communication abnormality between for example off-premises station 11 and the indoor set 12.The mistake of off-premises station 11, unusual for for example compressor 16 grades.
In addition, in control device 40, have: the compressor of pushing timer 43A, when compressor 16 is forced to shut down after through first stipulated time (for example 3 minutes) first stipulated time (for example 3 minutes) being carried out timing that the compressing time of maintenance switch 31 clocks is forced timer 43B, and switch to the address setting timer 43C that second stipulated time (for example 5 seconds) is carried out timing after the address setting pattern described later.
In the operation mode of present embodiment, have: carry out the cooling operation pattern of cooling operation, carry out the heating operation mode of heating running, carry out the dry operating pattern of dry operating, and the operation mode with fresh air that carries out the fresh air running.
When carrying out the cooling operation pattern of cooling operation, the cold-producing medium of discharging from compressor 16 is shown in solid arrow on the cross valve 18, through cross valve 18 inflow outdoor heat exchangers 19, the cold-producing medium of Liu Chuing flows into indoor set 12 after expanding in electrodynamic type expansion valve 22 places from here.Then, evaporation flows to cross valve 18 in indoor heat exchanger 21, returns in the compressor 16 via accumulator 17.By this indoor heat converter 21, the room air that is directed in the indoor set 12 is cooled, and carries out indoor refrigeration.When carrying out the dry operating pattern of dry operating, carry out the weak cooling operation lower, carry out indoor dehumidification than cooling operation refrigerating capacity.
When carrying out the heating operation mode of heating running, the cold-producing medium of discharging from compressor 16 flow in the indoor set 12 through cross valve 18 shown in dotted line on the cross valve 18.Flow through then, in turn indoor heat converter 21, electrodynamic type expansion valve 22, in the inflow outdoor heat exchanger 19, from then on the cold-producing medium that flows out is through turning back in the compressor 16 through accumulator 17 after the cross valve 18.So, indoor heat converter 19 has the function of condenser, by this indoor heat converter 31, the room air that is directed in the indoor set 12 is heated, and carries out indoor heating.
When carrying out the operation mode with fresh air of fresh air running, compressor 16 is stopped, the cross flow fan 23 that drives indoor set 12 is to indoor air-supply.
When switch 30,31 not being carried out pressing operation, control device 40 is turned round by the common operation mode of remote controller 34 according to the operation of carrying out operation of air conditioner.When this common operation mode, can carry out the operations such as setting, running/stop of design temperature of desired value of switching, the expression indoor temperature of operation mode by the operation of remote controller 34.
Usually, control device 40 carries out the operation that compressor 16 is shut down when stopping operation of air conditioner or switching the switching operation mode of cross valve 18 (Fig. 1).Be that aircondition 10 has the pressure stop mode of restarting after the running of forbidding compressor 16 in the very first time that running stops to begin stops.When air-conditioning shuts down or carried out switching cross valve 18 when switching operation modes, control device 40 controls transitions to the pressure stop mode.And then aircondition 10 has to be forbidden being converted to this pressure stop mode or stops the releasing pattern in beginning to the pressure of forcing stop mode conversion back to remove this pressure stop mode.
Fig. 3 is the circuit diagram of expression to the off-premises station power supply.Power supply is supplied with by omitting illustrated socket, by the power supply unit 37 that is provided with on the indoor set 12 each power devices to off-premises station 11.Just, power to off-premises station 11 through indoor set.To the power line 38 of off-premises station 11, has energy relay 39 from this power supply unit 37.
When aircondition 10 turned round under common operation mode usually, under the control of control device 40, energy relay 39 was opened to off-premises station 11 power supplies.
Promptly, as shown in Figure 4 when common operation mode, make mistake, garble or off-premises station 11 effectively wrong of fan electromotor 23A of mistake, the indoor set 12 of interior sensor 29,, automatically switch to the control of running stop mode in case these mistakes have taken place.
Whether aircondition 10 has the interior sensor 29 that is provided with on the indoor set 12 no matter and exists unusually, via the test running pattern of indoor set 12 to off-premises station 11 power supplies, and no matter whether indoor set 12 or off-premises station 11 exist unusually, ignore the tripping operation pattern through indoor set 12 to off-premises station 11 power supplies.
That is, the test running pattern is shown in Figure 4, makes the wrong invalid operation of air conditioner pattern of interior sensor 29.Even control device 40 detects the mistake of interior sensor 29, can not be converted to the running stop mode, with the remain in operation control of air-conditioning of test running pattern yet.
In addition, ignore the wrong invalid operation of air conditioner pattern of mistake, garble or off-premises station 11 that the tripping operation pattern is the fan electromotor 23A of the mistake that makes interior sensor 29, indoor set 12.Can not be converted to the running stop mode, with the remain in operation control of air-conditioning of tripping operation ignorance pattern.
When carrying out cooling operation, heating running and dry operating in this test running pattern, compressor 16 is fixed as the operating frequency of regulation.
In addition, when ignoring cooling operation in the tripping operation pattern, heating running and dry operating, compressor 16 operating frequency running as requested.
In the present embodiment, aircondition 10 has emergency operation pattern and service mode.As shown in Figure 2, under the situation of pressing operation emergency operation switch 30, control device 40 is carried out the control of being switched to the emergency operation pattern by common operation mode.In addition, under the situation of pushing attended operation switch 31 shown in Figure 2, control device 40 is carried out by common operation mode to the control of safeguarding that operation mode switches.
At first, illustrate when pushing emergency operation switch 30 with reference to flow process shown in Figure 5, by the control action of 40 pairs of emergent operation modes of control device.
According to the judgement of step S1, if emergency operation switch 30 carries out pressing operation, just be converted to the emergency operation pattern.Control device 40 is promptly judged the operation of air conditioner state (step S2) of the aircondition 10 behind the pressing operation emergency operation switch 30 now.
According to the judgement of step S2, timed unit 40 switched to the cooling operation pattern during running stopped, and was converted to the control (step S3) of cooling operation.At this moment, in display part 33, represent the demonstration of cooling operation.For example, make the green light of LED33C bright.
Be when switching to the cooling operation pattern among the step S4, set with by the corresponding design temperature of the detected indoor temperature of temperature sensor 29A (temperature now).This present temperature is for example pressing operation emergency operation switch 30, when operation mode is switched by the detected temperature of temperature sensor 29A.Specifically, design temperature is set to lower than present temperature.For example design temperature is set at and makes compressor operating reduce the set point of temperature also bigger than regulation deviation (for example 2 ℃) from present temperature.Therefore, when switching to the emergency operation pattern and being converted to cooling operation,,, improve heat pump performance so can make compressor 16 work because the deviation ratio of indoor temperature and set point of temperature regulation deviation (for example 1 ℃) is big.
Set in this step S4 and the corresponding design temperature scope of cooling operation (for example 20 ℃～30 ℃), design temperature is set at the value in this setting range.Therefore, for example when becoming more than 32 ℃ indoor urgent need refrigeration such as indoor temperature, in setting range, because design temperature is set at the higher limit (for example 30 ℃) of not damaging the heat pump performance degree, therefore compare with 36 ℃ the situation that when room temperature is 38 ℃, design temperature is set at low 2 ℃, improved heat pump performance more.For example be when there is no need to freeze below 22 ℃ in addition, for example, in the design temperature scope, design temperature be set at the lower limit (for example 20 ℃) of not damaging the heat pump performance degree, therefore can improve heat pump performance in indoor temperature.
In the judgement of step S2, when carrying out cooling operation (situation of cooling operation pattern), control device 40 is carried out and is switched to the control (step S5) that the heating operation mode is converted to the heating running.At this moment, in display part 33, represent the demonstration of heating running.For example make the red light of LED33C bright.At this moment cooling operation pattern is not limited to the situation by 30 settings of this emergency operation switch, also comprises the cooling operation pattern in the common operation mode that is switched by remote controller 24.
That is, when switching to the heating operation mode among the step S6, set with by the corresponding design temperature of the detected indoor temperature of temperature sensor 29A (temperature now).Specifically, design temperature is set to also higher than present temperature.For example design temperature makes compressor operating and is set at from the present temperature increase set point of temperature (for example 2 ℃) also bigger than regulation deviation.Therefore, switch to the emergency operation pattern and be converted to heating when running,,, improve heat pump performance so can make compressor 16 work because the deviation ratio of indoor temperature and set point of temperature regulation deviation (for example 1 ℃) is big.
Set in this step S6 and the heating corresponding design temperature scope (for example 20 ℃～26 ℃) that turns round, design temperature is set at the value in this setting range.Therefore, for example when becoming indoor urgent need heating below 18 ℃ such as indoor temperature, in setting range, because design temperature is set at the lower limit (for example 20 ℃) of not damaging the heat pump performance degree, therefore with when room temperature is 2 ℃, design temperature is set at 4 ℃ high 2 ℃ situation and compares, improved heat pump performance more.For example be when there is no need heating more than 24 ℃ in addition, for example, in the design temperature scope, design temperature be set at the higher limit (for example 26 ℃) of not damaging the heat pump performance degree, therefore can improve heat pump performance in indoor temperature.
In the judgement of step S2, when carrying out the heating running (situation of heating operation mode), control device 40 is carried out the control (step S7) that stops operation of air conditioner.At this moment heating operation mode is not limited to the situation by 30 settings of this emergency operation switch, also comprises the heating operation mode in the common operation mode that is switched by remote controller 34.
By this emergency operation switch 30 of pressing operation, can circulate and carry out stopping the switching of cooling operation heating running running stopping .. as running.Promptly since the switching that comprises the operation mode that stops of running capable of circulation therefore there is no need the running stop button to be set on main frame 12A by other approach.
The operation mode that can switch by this emergency operation switch 30 is for the necessary cooling operation pattern of case of emergency, though do not comprise dry operating pattern and operation mode with fresh air in the present embodiment, also can comprise these operation modes.
When other operation modes except that the cooling operation pattern (for example dry operating pattern and operation mode with fresh air), during pressing operation emergency operation switch 30, promptly in not comprising the emergency operation pattern in the running of the operation mode of the common operation mode of operation mode under the situation of pressing operation emergency operation switch 30, the control that control device 40 turns round and stops.Thus, in the time of in the emergency operation pattern, can not operating by remote controller 34 in the running of the operation mode of operation mode common operation mode not to be covered (for example remote controller 34 lose etc.), can shut down by this emergency operation switch 30 of pressing operation.
Below, with reference to flow process shown in Figure 6 the service mode control action that control device 40 about by pressing operation maintenance switch 31 time carries out is described.
The operation that this maintenance switch 31 can be followed emergency operation switch 30 is operated.Be that emergency operation switch 30 and maintenance switch 31 can independently be operated mutually.Therefore simple to operate, the operability height.
If maintenance switch 31 does not carry out pressing operation in step S11, return the judgement action of this step S11 once more.If maintenance switch 31 has carried out pressing operation in step S11, just be converted to service mode.
If maintenance switch 31 has carried out pressing operation in step S11, just begin by pushing timer 43A the compressing time timing, this compressing time is greater than 0 second during less than 1 second, control device 40 forbids that compressor 16 is to the conversion of forcing stop mode, or beginning carries out switching to the control (step S12) that the pressure of removing this pressure stop mode stops the pattern of removing after forcing the stop mode conversion.
Concrete, 40 pairs of compressors of control device force timer 43B to overflow control in step S12.Force timer 43B to overflow by making compressor, control device 40 can think that the running dwell time of compressor 16 passed through for first stipulated time (for example 3 minutes), if compressor 16 is on-stream, just forbid being converted to the pressure stop mode, if compressor 16 in running stops, just being removed the pressure stop mode of compressor 16.
Switch under the situation that this pressure stops the pattern of removing, such as the switching of the operation mode that switches cross valve 18 time (for example from of the switching of cooling operation pattern) to the heating operation mode, or when stopping to make operation of air conditioner once more behind the operation of air conditioner, can just make operation of air conditioner through first stipulated time.When safeguarding particularly as when the installation of aircondition 10 or during service etc., spended time does not carry out the change action of refrigeration and heating operation mode is confirmed.
Pressure stop mode and pressure at compressor 16 stop in the switching of the pattern of removing, and are undertaken from forcing stop mode to stop the switching of the pattern of removing to pressure by the pressing operation to maintenance switch 31.Pressure stops the releasing of the pattern of removing, and promptly carries out automatically to the conversion of common operation mode from forcing to stop the releasing pattern.Be that maintenance switch 31 can unidirectionally force to stop the releasing pattern from forcing stop mode to switch to.
Pressure stops the releasing of the pattern of removing, can be for example behind the handover operation of the operation mode that switches cross valve 18, after perhaps stopping to make the operation of operation of air conditioner once more behind the operation of air conditioner, carry out automatically by control device 40.
If the processing of step S12 action finishes, just switch to normal mode from service mode, return the judgement action in S11 step once more and handle.
In the judgement of step S11, if the compressing time of maintenance switch 31 between 1 second and 5 seconds, control device 40 makes buzzer 35 sound once (step S13), judges air-conditioning whether on-stream (step S14).
As being not limited to common operation mode in the operation of air conditioner in the judgement of this step S14, also can be the operation of air conditioner in the emergency operation pattern of being switched by emergency operation switch 30.
If air-conditioning is on-stream in the judgement of step S14, control device 40 controls switch to and operation of air conditioner (cooling operation, heating running, dry operating and running with fresh air) corresponding test running pattern (step S15).If for example in cooling operation, control device 40 controls are converted to the test running pattern of cooling operation.
In the test running pattern, during pressing operation emergency operation switch 30, control device 40 is carried out the control that stops operation of air conditioner in operation of air conditioner.Like this, owing to the operation of air conditioner that can stop by operation in the test running pattern, so on main frame 12A (Fig. 2), there is no need to be provided with the running shutdown switch to emergency operation switch 30.
If the processing of step S15 action finishes, just switch to common operation mode from service mode, return the judgement action of step S11 once more and handle.
In the judgement of step S14, if running stops, control device 40 is carried out the control (step S16) of the OBD pattern of expression in display part 33 that the abnormal information of storage in the storage part 42 is switched to.
In this step S16, the abnormal information of storage is by the modal representation of the bright lamp of stipulating among LED33A, 33B, the 33C in the display part 33 in the storage part 42.The abnormal information of storage begins to represent in turn from new abnormal information in this storage part 42.
After the processing release of step S16, the OBD pattern is disengaged, and switches to normal mode from service mode, and the judgement action that turns back to step S11 is once more handled.
In the judgement of step S11, if the compressing time of maintenance switch 31 more than 5 seconds, control device 40 makes twice of buzzer 35 sound (step S17), judges air-conditioning whether on-stream (step S18).
As being not limited to common operation mode in the operation of air conditioner in the judgement of this step S18, also can be the operation of air conditioner in the emergency operation pattern of being switched by emergency operation switch 30.
In the judgement of step S18, if air-conditioning is on-stream, control device 40 is carried out and is switched to and the control (step S19) of pattern is ignored in the corresponding tripping operation of operation of air conditioner (cooling operation, heating running, dry operating and running with fresh air).For example in the cooling operation, control device 40 is carried out the control of ignoring the tripping operation pattern that is converted to cooling operation.
In addition, control device 40 is not accepted the control of the operation of remote controller 34 when tripping operation ignorance pattern.
In addition, in tripping operation ignorance pattern, during pressing operation emergency operation switch 30, control device 40 stops the control of operation of air conditioner in operation of air conditioner.Because by can stop to trip the operation of air conditioner in the ignorance pattern of the operation to this emergency operation switch 30, so on main frame 12A (Fig. 2), there is no need to be provided with again in addition the running shutdown switch.Like this, owing to possessed tripping operation ignorance pattern, can therefore can improve maintainability to off-premises station 11 constrained feeds during upkeep operation.
In the switching of running stop mode and tripping operation ignorance pattern, the switching that stops the pattern of removing from the running stop mode to pressure is undertaken by pressing operation maintenance switch 31.Automatically carry out to the conversion of running stop mode from tripping operation ignorance pattern.Be that maintenance switch 31 can unidirectionally switch to tripping operation ignorance pattern from the running stop mode.
After the processing release of step S15, switch to common operation mode, return the judgement action of step S11 once more and handle from service mode.
