And the warm water after will heating in heat-transfer pipe 1 7A of evaporimeter 5 inside supplies to via the outlet 17B of cold warm water tube 17 circulation does not have illustrated indoor unit, makes warm running etc. thus.
The present invention possesses the control part 33 of controlling the running that absorbs liquid pump 12 based on the detection of horizontal detector 30, detect the absorption liquid level when lower limit is following at horizontal detector 30, make and absorb liquid pump 12 to run up the stipulated time, to increase the absorption liquid measure of sending into to high-temp regenerator 1, during when arriving this stipulated time or through this stipulated time, whether control part 33 determined level detectors 30 detect absorbs liquid level below lower limit.Thus, detect the absorption liquid level when lower limit is following at horizontal detector 30, control part 33 is controlled, to sound the alarm and to stop the running both sides of absorption cooling and warming water machine P or carry out a wherein side operation.
Concrete structure is as described below.Be input to control part 33 with detecting the detection output of temperature detecting part 29 of absorption liquid temperature of the detection high-temp regenerator 1 that is provided with as the temperature detection of high-temp regenerator and the detection of temperature detecting part 34 that detects the inlet temperature of the cooling water that flows into to cooling water pipe 18.Then, in cooling operation, according to the detection output of temperature detecting part 29 and the detection output of temperature detecting part 34, as shown in Figure 3, the inlet temperature that makes cooling water is for example corresponding to each scopes of per 2 ℃ of regulations of 22 ℃～32 ℃, when the absorption liquid temperature of high-temp regenerator 1 is for example changed in 90 ℃～160 ℃ scope, frequency is for example changed in the scope of 28Hz～60Hz continuous or interimly, thus, the absorption liquid temperature of high-temp regenerator 1 is high more, then make the frequency signal of control part 33 outputs become high frequency signal more by input from temperature detecting part 29, become high frequency from Frequency Converter Control portion 32 more to the frequency of the electric power of the motor output that absorbs liquid pump 12, thereby make absorption liquid pump 12 become the state of running up more, make the discharge rate that absorbs liquid pump 12 increase.In addition, the absorption liquid temperature of high-temp regenerator 1 is low more, make the frequency signal of control part 33 outputs become low frequency signal more by input from temperature detecting part 29, become low frequency from Frequency Converter Control portion 32 more to the frequency of the electric power of the motor output that absorbs liquid pump 12, thereby make absorption liquid pump 12 become the low-speed running state more, make the discharge rate that absorbs liquid pump 12 reduce.
In addition, in the warm running of system, as mentioned above, because cooling water does not flow through cooling water pipe 18, so, according to the detection output of detection to the temperature detecting part 29 of the absorption liquid temperature of the high-temp regenerator 1 of control part 33 inputs, as mentioned above, the absorption liquid temperature of high-temp regenerator 1 is high more, then make the frequency signal of control part 33 outputs become high frequency signal more by input from temperature detecting part 29, become high frequency from Frequency Converter Control portion 32 more to the frequency of the electric power of the motor output that absorbs liquid pump 12, absorbing liquid pump 12 becomes the state of running up more, makes the discharge rate that absorbs liquid pump 12 increase.In addition, when the absorption liquid temperature of high-temp regenerator 1 low more, then make the frequency signal of control part 33 outputs become low frequency signal more by input from temperature detecting part 29, become low frequency from Frequency Converter Control portion 32 more to the frequency of the electric power of the motor output that absorbs liquid pump 12, absorbing liquid pump 12 becomes the low-speed running state more, makes the discharge rate that absorbs liquid pump 12 reduce.
Like this, by at least according to the absorption liquid temperature of high-temp regenerator 1, make from the Frequency Converter Control portion 32 of control part 33 frequency change to the electric power that absorbs liquid pump 12 outputs, carry out VFC for absorbing liquid pump 12, so that absorb the rotation speed change of liquid pump 12, thereby the absorption liquid level of keeping high-temp regenerator 1 is at suitable absorption liquid level.
In addition, in the above-mentioned situation, the detection of the temperature detecting part 29 of the absorption temperature of the temperature detection of high-temp regenerator by detecting high-temp regenerator 1 is carried out, but the detection of the Temperature Detector 31 of temperature of exhaust gas that also can be by detecting high-temp regenerator 1 is carried out.
Like this, the absorption liquid level is more than the electrode C and the absorption liquid measure of the scope below electrode A is normal state, under this state, as shown in Figure 3, carry out VFC in the scope of 28Hz～60Hz for absorbing liquid pump 12 as mentioned above, but under this operating condition, when for a certain reason, and under the situation that the rising of the liquid level of absorption liquid frequently takes place at short notice, then reduce to absorbing the power frequency that liquid pump 12 is supplied with.For example, when the power frequency of supplying with to the absorption liquid pump 12 that is in operating condition by VFC is 40Hz, by control part 33 statistics at the appointed time (for example, during 10 seconds) absorb the number of times that liquid level arrives electrode A, when it reaches stipulated number (for example 3 times), then control part 33 is controlled, and makes to absorb liquid pump 12 runnings or make with the low-limit frequency 28Hz of VFC scope and absorbs liquid pump 12 runnings to reduce 30Hz after the assigned frequency (for example 10Hz) from 40Hz.Thus, the frequent at short notice abnormality that takes place even the liquid level of absorption liquid rises also can make absorption cooling and warming water machine P steady operation.
