Energy-saving operation parts of the present invention below are described.
Before this, common running gear for this engine-driven type air conditioning device 100 is illustrated, in this common running gear, running/the shutdown switch 41 and the temperature setting switch 44 of operating portion 40 are operated, during from the 30 indication runnings of 40 pairs of control device of operating portion, for example, the temperature difference of the indoor temperature that detects according to the not shown temperature sensor of each indoor unit 2a, 2b and the design temperature of described temperature setting switch 44 indications etc., calculate and add up to each air conditioner load Ha, the Hb of each indoor unit 2a, 2b, calculate comprehensive air conditioner load Hs.When the air conditioner load Hs that this is comprehensive represents with Fig. 3, then as shown in Figure 5, for example, establish described air conditioner load Hs, then calculate rotating speed MK1 as the target of engine 10 and compressor 11 for becoming an a at an a.Thus, change from the described rotating speed MK1 of 30 pairs of engines 10 of control device and the compressor 11 indications line space allocation and transportation of going forward side by side as rotating speed of target, this running and the common running gear that carries out in aircondition before are without any difference.
In contrast, in the present invention, the power down switch 45 of described operating portion 40 is carried out when operating for the first time, the data of the running efficiency KE of the Fig. 3 that stores among the RAM34 according to described control device 30, KC or KS, ask described engine 10 and compressor 11 both sides' running efficiency KE, KC to be optimum some b, described some a is altered to described some b, will turns round as the rotating speed MK2 that becomes this b as the rotating speed of target of the target of described engine 10 and compressor 11.In addition, this b is the running efficiency KC both sides' of the running efficiency KE of engine 10 and compressor 11 a running efficiency, perhaps is that described overall efficiency KS is optimum rotating speed.
And when using these energy-saving operation parts of flowchart text shown in Figure 6, at first, judge whether this engine-driven type air conditioning device 100 is in (step S1) in the running, if it is not on-stream, then return step S1, whether repeat is judgement in the running, if it is on-stream, each indoor unit 2a that represents according to above-mentioned Fig. 1 then, the temperature difference of the design temperature of setting in indoor temperature that the not shown temperature sensor that is provided with among the 2b detects and the operating portion 40 etc., calculate each indoor unit 2a, the air conditioner load Ha of 2b, Hb also asks comprehensive air conditioner load Hs, and asks the engine 10 of this air conditioner load Hs correspondence and the rotating speed MK1 (step S2) of compressor 11.
Afterwards, the power down switch 45 of described operating portion 40 is carried out operation, whether the execution of judging energy-saving operation parts of the present invention is instructed to (step S3), if the execution of described energy-saving operation parts is not instructed to, then carry out judgement for above-mentioned common running gear, carry out and to be made as the rotating speed MK1 (point of Fig. 5 indication of asking according to described air conditioner load Hs (step S4) a) as the rotating speed MK of the target of described engine 10 and compressor 11, (be the described some running of a) carrying out engine 10 and compressor 11, and carry out running (step S5) with this rotating speed MK according to described air conditioner load Hs.
In contrast, if the execution of the described energy-saving operation parts of indication in step S3, then according to being stored in engine 10 above-mentioned shown in Figure 3 in the RAM34 of control device 30 and each running efficiency KE of compressor 11, the data of KC, running efficiency KE, the KC that asks both sides is optimum rotating speed MK2 (the some b of Fig. 5), carry out the indication (step S6) as rotating speed MK2, carry out the running (step S7) of described engine 10 and compressor 11 with this rotating speed MK (being described some b) with described rotating speed MK.
Thus, in this engine-driven type air conditioning device 100, owing to can automatically carry out the operation of air conditioner of the some b of running efficiency KS optimum, use the refrigerating capacity height and the few described replacement cold-producing medium R410a of the pressure loss of per unit volume simultaneously, so can further advance energy-conservation operation of air conditioner.
And then, in these energy-saving operation parts, the power down switch 45 of operating portion 40 is operated and the execution of described energy-saving operation parts when being instructed to as described above, also can not be made as the rotating speed MK2 of described running efficiency KE, KC or overall efficiency KS optimum, the rotating speed MK3 of described running efficiency KE, KC or described overall efficiency KS optimum in prescribed limit for described air conditioner load Hs, and make its running.
For example, described regulation limit of power is made as 80% of described air conditioner load Hs~120% o'clock, as shown in Figure 7, even the engine of obtaining according to described air conditioner load Hs 10 and the rotating speed MK1 of compressor 11 are at an a, power down switch 45 by operating portion 40 is operated and the execution of described energy-saving operation is instructed to, described rotating speed MK1 is also changed to 80% rotating speed MK3 of the lower limit of described regulation limit of power, and engine 10 and compressor 11 also can turn round at this rotating speed MK3 (c point).
The refrigerating capacity Rn1 that obtains when it is turned round with the rotating speed MK1 that obtains based on described air conditioner load Hs is made as 100%, about refrigerating capacity Rsum1 in order to obtain after obtaining, and the total rate of fuel consumption amount Fsum1 that for this reason consumes, become 80% MK3 with described rotating speed MK1 being made as by described energy-saving operation parts of the present invention, thereby the refrigerating capacity Rsum2 of the described total refrigerating capacity Rsum1 when being equivalent to turn round and essential Fuel Consumption Fsum2, when describing with reference to the fuel consumption efficiency curve map of Fig. 8, carry out operation of air conditioner and when obtaining total refrigerating capacity Rsum1 with the rotating speed MK1 that obtains based on described air conditioner load Hs, running efficiency is also left from the some b that becomes peak efficiency, and descend about 1.6, simultaneously to be turned round than the more high-revolving rotating speed MK1 of described rotating speed MK3, so certainly fuel consumption improves, 62.5% of the Fuel Consumption Fmax during for the rotating the most at a high speed of engine 10.In contrast, when carrying out described energy-saving operation parts of the present invention, as mentioned above, become running with 80% the rotating speed MK3 of described rotating speed MK1, so running efficiency also becomes the some c near best efficiency point b, and improving approximately 1.8, the rotating speed of engine 10 also reduces simultaneously, so the specific fuel consumption of this moment is reduced to 44.4% of described Fuel Consumption Fmax.Therefore, in order to obtain being equivalent to total refrigerating capacity Rsum2 of described total refrigerating capacity Rsum1, with based on described air conditioner load Hs the situation of its running is compared, increase by 25% the duration of runs, but this moment total fuel consumption Fsum1 can reduce 11.1% for described Fsum1.
And then, by carrying out this energy-saving operation parts, even the refrigerating capacity that obtains descends, as mentioned above, because lower limit is set as 80% of air conditioner load Hs that indoor unit 2a, 2b require, so described refrigerating capacity does not descend more than necessity, can advance energy-saving operation and do not bring unplessantness displeasure to the user.
And, energy-saving operation parts for the running efficiency optimum that carries out such engine 10 and 11 liang of sides of compressor, as mentioned above, not with the data of described running efficiency KE, and the data of described running efficiency KC, the data of perhaps described overall efficiency KS store RAM34 into, for example, to ask the arithmetic expression of described overall efficiency KS to store ROM33 etc. into, also can control like that by flow chart as shown in Figure 9.
At this moment, at first, judge this engine-driven type air conditioning device 100 whether on-stream (step S10), if it is not on-stream, then return step S10, repeat this whether on-stream judgement, if on-stream, then air conditioner load Ha, the Hb according to above-mentioned each indoor unit 2a, 2b shown in Figure 1 asks comprehensive air conditioner load Hs, and asks corresponding to the engine 10 of this air conditioner load Hs and the rotating speed MK1 (step S11) of compressor 11.
Afterwards, judge whether the energy-saving operation parts are performed (step S12), if do not indicate the execution of energy-saving operation parts, then carry out being the judgement of running gear usually, to be made as the indication of trying to achieve rotating speed MK1 as the rotating speed MK of the target of described engine 10 and compressor 11 and be carried out (step S13) according to described air conditioner load Hs, the running (step S14) of described air conditioner load Hs correspondence is carried out in the running that engine 10 and compressor 11 carry out at described some a.
In contrast, if the execution of the described energy-saving operation parts of indication in step S12, become 80% the air conditioner load Hs1 of described air conditioner load Hs, and 120% the air conditioner load Hs2 that becomes described air conditioner load obtained (step S15) according to the arithmetic expression of storage among the above-mentioned ROM35 etc., is equivalent to the engine 10 of this air conditioner load Hs1, Hs2 that obtains and each rotating speed MKa, the MKb of compressor 11 and obtained (step S16).Then, judge that rotating speed MKa is whether than the described rotating speed MK2 big (step S17) of overall efficiency KS optimum, if MKa is little for rotating speed MK2 specific speed, then described rotating speed MK is made as rotating speed MKa (step S18), proceed to step S22, if MKa is big for rotating speed MK2 specific speed, then carry out the whether big judgement (step S19) of specific speed MKb of this rotating speed MK2, if MKb is big for rotating speed MK2 specific speed, then described rotating speed is made as rotating speed MKb (step S20), proceeds to step S22, if rotating speed MK2 specific speed MKb is little, then described rotating speed MK is made as rotating speed MK2 (step S21), makes engine 10 and compressor 11 runnings (step S22) with rotating speed MK.
Thus, this engine-driven type air conditioning device 100 automatically running efficiency KS is best, can not bring the some c of unplessantness displeasure to carry out operation of air conditioner to the user, use the refrigerating capacity height and the few described replacement cold-producing medium R410a of the pressure loss of per unit volume simultaneously, so can also advance energy-conservation operation of air conditioner.
