Referring again to Fig. 1。Thermal medium stream 22 is the pipe arrangement making thermal medium be circulated again into heat storage tank 12 through the regenerator 101 of absorption-type cold-hot water dispenser 21 from heat storage tank 12。Wherein, regenerator 101 stream going to absorption-type cold-hot water dispenser 21 from heat storage tank 12 is called the 1st thermal medium stream 22a, and the stream going to heat storage tank 12 from the regenerator 101 of absorption-type cold-hot water dispenser 21 is called the 2nd thermal medium stream 22b。
Thermal medium pump 23 is located at the 1st thermal medium stream 22a in thermal medium stream 22, is the power source making thermal medium be circulated again into heat storage tank 12 through the regenerator 101 of absorption-type cold-hot water dispenser 21 from heat storage tank 12。
And, in present embodiment, absorption type cold-hot water system 1 includes switching valve 31, bypass stream 32, heat collector temperature sensor (the 1st temperature sensor) 33, heat storage tank temperature sensor (the 2nd temperature sensor) 34, check-valves 35, system controller (control unit) 36。
Switching valve 31 is provided in from solar heat heat collector 11 to the stream of heat storage tank 12, i.e. three-way valve on the 2nd thermal-arrest stream 13b。Bypass stream 32 is that the 1st thermal medium stream 22a is the stream supplying thermal medium from heat storage tank 12 to absorption-type cold-hot water dispenser 21 by the 1st thermal medium stream 22a pipe arrangement being connected with switching valve 31。Switching valve 31 is controlled by system controller 36, the thermal medium heated by solar heat heat collector 11 is only supplied to heat storage tank 12 by the 2nd thermal-arrest stream 13b, or is supplied to the regenerator 101 of absorption-type cold-hot water dispenser 21 by bypassing stream 32 not via heat storage tank 12。
Heat collector temperature sensor 33 detects the temperature of the thermal medium from solar heat heat collector 11, sends signal corresponding with heat medium temperature to system controller 36。Heat storage tank temperature sensor 34 detects the temperature of the thermal medium in heat storage tank 12, sends signal corresponding with heat medium temperature to system controller 36。
Check-valves 35 is located at the downstream of the 1st thermal medium stream 22a upstream side with the junction point A of bypass stream 32 and thermal medium pump 23, it is prevented that the refluence of thermal medium。
System controller 36 includes CPU (CentralProcessingUnit, CPU), according to the heat medium temperature detected by heat collector temperature sensor 33, the heat medium temperature that detected by heat storage tank temperature sensor 34, controls switching valve 31。
System controller 36 is when the heat medium temperature detected by heat collector temperature sensor 33 exceeds more than predetermined temperature than the heat medium temperature detected by heat storage tank temperature sensor 34, control switching valve 31, by bypassing stream 32, the thermal medium from solar heat heat collector 11 is supplied the regenerator 101 to absorption-type cold-hot water dispenser 21。Thus, under the situation that the thermal medium from solar heat heat collector 11 is higher than the heat medium temperature from heat storage tank 12, directly supply thermal medium to absorption-type cold-hot water dispenser 21 from solar heat heat collector 11, absorption-type cold-hot water dispenser 21 carries out efficiency operating more preferably。
Additionally, system controller 36 is when the heat medium temperature detected by heat collector temperature sensor 33 is below the heat medium temperature detected by heat storage tank temperature sensor 34, control switching valve 31, make the thermal medium from solar heat heat collector 11 supply to heat storage tank 12。Therefore, poor at sunshine environment, temperature from the thermal medium of solar heat heat collector 11 is under the situation below the temperature of the thermal medium of heat storage tank 12, does not directly supply thermal medium to absorption-type cold-hot water dispenser 21 from solar heat heat collector 11, it is prevented that the state of affairs that efficiency declines。
In addition, system controller 36 does not exceed more than predetermined temperature than the heat medium temperature detected by heat storage tank temperature sensor 34 at the heat medium temperature detected by heat collector temperature sensor 33, and the heat medium temperature detected by heat collector temperature sensor 33 is not when being below the heat medium temperature detected by heat storage tank temperature sensor 34, maintain switching valve 31 with current state。That is, the control switching valve 31 is provided with temperature lag, it is prevented that switching valve 31 frequently switches。
It addition, system controller 36 is when passing through regenerator 101 that the thermal medium from solar heat heat collector 11 is supplied to absorption-type cold-hot water dispenser 21 by bypass stream 32, does not make thermal medium pump 23 action, make heat-collecting pump 14 action。Thus, make an action in 2 pumps 14,23, make the thermal medium from solar heat heat collector 11 supply the regenerator 101 to absorption-type cold-hot water dispenser 21。
It follows that the control method switching valve 31 of the absorption type cold-hot water system 1 involved by explanation present embodiment。Fig. 3 is the flow chart of the control method illustrating the absorption type cold-hot water system 1 involved by present embodiment。Additionally, repeatedly perform the process shown in Fig. 3, until absorption type cold-hot water system 1 stops。It addition, in figure 3, heat collector temperature sensor 33 heat medium temperature detected is shown as T1 (meansigma methods T1ave), heat storage tank temperature sensor 34 heat medium temperature detected is shown as T2 (meansigma methods T2ave)。
First, as it is shown on figure 3, system controller 36 judge the heat medium temperature T1 detected by heat collector temperature sensor 33 be whether proper temperature and the thermal medium allowable temperature that be supplied to absorption-type cold-hot water dispenser 21 higher limit more than (S1)。When being judged as YES more than higher limit (S1: yes), switching valve 31 is switched to heat storage tank 12 side (S2) by system controller 36。Then, the process shown in Fig. 3 terminates。Now, two pumps 14,23 are all in operating condition。
On the other hand, when the heat medium temperature T1 being judged as being detected by heat collector temperature sensor 33 is not more than higher limit (S1: no), system controller 36 judges whether the rolling average temperature T1ave of the heat medium temperature T1 detected by heat collector temperature sensor 33 exceeds predetermined temperature more than Δ T (S3) than the rolling average temperature T2ave of the heat medium temperature T2 detected by heat storage tank temperature sensor 34。
Then, when being judged as exceeding predetermined temperature more than Δ T (S3: yes), switching valve 31 is switched to bypass stream 32 side (S4) by system controller 36。Then, the process shown in Fig. 3 terminates。Now, heat-collecting pump 14 is operating condition, but thermal medium pump 23 is in halted state。
Additionally, when being judged as that the rolling average temperature T1ave of the heat medium temperature T1 detected by heat collector temperature sensor 33 does not exceed predetermined temperature more than Δ T than the rolling average temperature T2ave of the heat medium temperature T2 detected by heat storage tank temperature sensor 34 (S3: no), system controller 36 judges that whether the rolling average temperature T1ave of the heat medium temperature T1 detected by heat collector temperature sensor 33 is below the rolling average temperature T2ave (S5) of the heat medium temperature T2 detected by heat storage tank temperature sensor 34。
When below the rolling average temperature T2ave that the rolling average temperature T1ave being judged as the heat medium temperature T1 detected by heat collector temperature sensor 33 is the heat medium temperature T2 detected by heat storage tank temperature sensor 34 (S5: yes), switching valve 31 is switched to heat storage tank 12 side (S2) by system controller 36。Then, the process shown in Fig. 3 terminates。Now, two pumps 14,23 are all in operating condition。
On the other hand, not being when below the rolling average temperature T2ave of the heat medium temperature T2 detected by heat storage tank temperature sensor 34 (S5: no) at the rolling average temperature T1ave being judged as the heat medium temperature T1 detected by heat collector temperature sensor 33, system controller 36 maintains switching valve 31 (S6) with current state。Then, the process shown in Fig. 3 terminates。Now, the state of two pumps 14,23 is also maintained。
By so, absorption type cold-hot water system 1 involved by present embodiment, when the heat medium temperature T1 detected by heat collector temperature sensor 33 exceeds predetermined temperature more than Δ T than the heat medium temperature T2 detected by heat storage tank temperature sensor 34, by bypassing stream 32, the thermal medium from solar heat heat collector 11 is supplied the regenerator 101 to absorption-type cold-hot water dispenser 21 owing to controlling switching valve 31, therefore under the situation that the thermal medium from solar heat heat collector 11 is higher than the temperature of the thermal medium from heat storage tank 12, directly thermal medium is supplied to absorption-type cold-hot water dispenser 21 from solar heat heat collector 11, absorption-type cold-hot water dispenser 21 can carry out efficiency operating more preferably。Thus it is possible to provide a kind of absorption type cold-hot water system 1 that can improve running efficiency further。
It addition, at the heat medium temperature T1 detected by heat collector temperature sensor 33 when below the heat medium temperature T2 detected by heat storage tank temperature sensor 34, make the thermal medium from solar heat heat collector 11 supply to heat storage tank 12。And, predetermined temperature more than Δ T is not exceeded than the heat medium temperature T2 detected by heat storage tank temperature sensor 34 at the heat medium temperature T1 detected by heat collector temperature sensor 33, and the heat medium temperature T1 detected by heat collector temperature sensor 33 is not when below the heat medium temperature T2 detected by heat storage tank temperature sensor 34, maintain switching valve 31 with current state。So, the control switching valve 31 is provided with temperature lag, it is possible to prevent switching valve 31 from frequently switching。
Additionally, when the heat medium temperature T1 detected by heat collector temperature sensor 33 is supply to the higher limit of the proper temperature of absorption-type cold-hot water dispenser 21 and thermal medium allowable temperature, control switching valve 31, make the thermal medium from solar heat heat collector 11 supply to heat storage tank 12。Therefore, even if the heat medium temperature T1 detected by heat collector temperature sensor 33 exceeds predetermined temperature more than Δ T than the heat medium temperature T2 detected by heat storage tank temperature sensor 34, by bypassing stream 32, the thermal medium from solar heat heat collector 11 is supplied to the situation of the regenerator 101 of absorption-type cold-hot water dispenser 21, when the heat medium temperature T1 detected by heat collector temperature sensor 33 is more than the higher limit of thermal medium allowable temperature, thermal medium is made to supply to heat storage tank 12。Thus, regenerator 101 is prevented from concentrated solution overrich etc., brings damage to absorption-type cold-hot water dispenser 21。
Additionally, when passing through regenerator 101 that the thermal medium from solar heat heat collector 11 is supplied to absorption-type cold-hot water dispenser 21 by bypass stream 32, owing to not making thermal medium pump 23 action, make heat-collecting pump 14 action, therefore an action in 2 pumps 14,23 is only made such that it is able to the thermal medium from solar heat heat collector 11 is supplied the regenerator 101 to absorption-type cold-hot water dispenser 21。
