To illustrate that below the adsorption type air-conditioning system 100 of present embodiment carries out the state of each stroke of absorption refrigeration.
At first, as shown in Figure 2, the liquid level that senses the first refrigerant liquid 311 in the first sub-vacuum chamber 31 and the second sub-vacuum chamber 32 and the second refrigerant liquid 321 when first LS 91 and second LS 92 is all when the highest or minimum, controller 90 can see through executes formula control, to control first triple valve 431, second triple valve 441, the switching state of the 3rd triple valve 531 and the 4th triple valve 541, and force hot water to feed in first adsorbent bed 40 and cooling water is fed in second adsorbent bed 50, again or force hot water to feed in second adsorbent bed 50 and cooling water is fed in first adsorbent bed 40.
If make cooling water feed and discharge first adsorbent bed 40 by first triple valve 431 and second triple valve 441, and hot water is fed and when discharging second adsorbent bed 50 via the 3rd triple valve 531 and the 4th triple valve 541, in the first sub-vacuum chamber 31, then can cool off step-down and refrigerant evaporation absorption stroke, so that the adsorbent in first adsorbent bed 40 can produce suction-operated to the first refrigerant liquid 311, and utilize evaporimeter 80 to make the 3rd refrigerant liquid 71 be evaporated to refrigerant steam, to reach the effect of refrigeration.And simultaneously in the second sub-vacuum chamber 32, then can heat and boost and the refrigerant desorption stroke that condenses,, and can make it be condensed into refrigerant liquid and the second refrigerant liquid, 321 liquid levels are risen by the second sub-condenser 62 so that but the adsorbent desorption in second adsorbent bed 50 goes out refrigerant steam.
As shown in Figure 3, detect liquid level in the first sub-vacuum chamber 31 and the second sub-vacuum chamber 32 when reaching minimum and the highest simultaneously, just remove and execute formula and control and continue next stroke up to first LS 91 and second LS 92.And be in low liquid level and second LS 92 and detect the second refrigerant liquid 321 when being in high liquid level when first LS 91 detects the first refrigerant liquid 311, then hot water is fed and discharge first adsorbent bed 40, and control the 3rd triple valve 531 and the 4th triple valve 541 makes cooling water feed and discharge second adsorbent bed 50 by controller 90 control first triple valves 431 and second triple valve 441.
Therefore, can heat in the first sub-vacuum chamber 31 and boost and the refrigerant desorption stroke that condenses,, and can refrigerant steam be condensed into refrigerant liquid and make the first refrigerant liquid, 311 liquid levels begin to rise by the first sub-condenser 61 so that but the adsorbent desorption in first adsorbent bed 40 goes out refrigerant steam.In the second sub-vacuum chamber 32, then can cool off step-down and refrigerant evaporation absorption stroke, and then allow the adsorbent in second adsorbent bed 50 produce suction-operateds to the second refrigerant liquid 321, so that the second refrigerant liquid 321 begins to descend, and utilize evaporimeter 80 to make the 3rd refrigerant liquid 71 be evaporated to refrigerant steam, to reach the effect of refrigeration.
As shown in Figure 4, when second adsorbent bed 50 continues to cool off step-down and refrigerant evaporation absorption stroke, when first LS 91 detects the first refrigerant liquid 311 when being in high liquid level, then make cooling water feed and discharge first adsorbent bed 40 by controller 90 control first triple valves 431 and second triple valve 441, so that in the first sub-vacuum chamber 31, can cool off step-down and refrigerant evaporation absorption stroke, and then allow the adsorbent in first adsorbent bed 40 produce suction-operateds to the first refrigerant liquid 311, so that the first refrigerant liquid 311 begins decline, and utilize evaporimeter 80 to make the 3rd refrigerant liquid 71 be evaporated to refrigerant steam.And first adsorbent bed 40 and second adsorbent bed 50 carry out the effect of absorption refrigeration simultaneously in the same running time at this moment.
And for example shown in Figure 5, when first adsorbent bed 40 continues to cool off step-down and refrigerant evaporation absorption stroke, when second LS 92 detects the second refrigerant liquid 321 when being in low liquid level, represent that promptly second adsorbent bed 50 has been finished the cooling step-down and refrigerant evaporation adsorbs stroke, and can make hot water feed and discharge second adsorbent bed 50 by controller 90 control the 3rd triple valves 531 and the 4th triple valve 541, heat so that can continue in the second sub-vacuum chamber 32 and to boost and the refrigerant desorption stroke that condenses, but and then make the adsorbent desorption in second adsorbent bed 50 go out refrigerant steam, and can refrigerant steam be condensed into refrigerant liquid and make the second refrigerant liquid, 321 liquid levels begin to rise by the second sub-condenser 62.
Then as shown in Figure 6, when first adsorbent bed 40 continues to cool off step-down and refrigerant evaporation absorption stroke, when second LS 92 detects the second refrigerant liquid 321 when being in high liquid level, represent that promptly second adsorbent bed 50 finished that heating is boosted and the refrigerant desorption stroke that condenses, therefore can make cooling water feed and discharge second adsorbent bed 50 by controller 90 control the 3rd triple valves 531 and the 4th triple valve 541, and make second adsorbent bed 50 can cool off step-down and refrigerant evaporation absorption stroke, and then allow the adsorbent in second adsorbent bed 50 produce suction-operateds to the second refrigerant liquid 321, so that the second refrigerant liquid 321 begins decline, and utilize evaporimeter 80 to make the 3rd refrigerant liquid 71 be evaporated to refrigerant steam.That is to say that first adsorbent bed 40 and second adsorbent bed 50 carry out the effect of absorption refrigeration simultaneously in the same running time.
As shown in Figure 7, when second adsorbent bed 50 continues to cool off step-down and refrigerant evaporation absorption stroke, first adsorbent bed 40 also begins to heat and boosts and the refrigerant desorption stroke that condenses, and make the first refrigerant liquid 311 continue to descend, detect the first refrigerant liquid 311 when being in low liquid level up to first LS 91, promptly represent first adsorbent bed 40 stroke of having finished that heating is boosted and the refrigerant desorption condenses.Next, can be at the stroke that continues as shown in Figure 4, and then constantly freeze again and again.
Because the time of heating is boosted and the refrigerant desorption condenses stroke is less than cooling step-down and the refrigerant evaporation absorption required time of stroke, therefore behind arbitrary sub-vacuum chamber 31 or 32 stroke of finishing that heating is boosted and the refrigerant desorption condenses, another sub-vacuum chamber 31 or 32 is still continuing to cool off step-down and refrigerant evaporation absorption stroke.But again because each sub-vacuum chamber 31,32 independent operation all, the sub-vacuum chamber 31 or 32 of the stroke of therefore having finished that heating is boosted and the refrigerant desorption condenses can directly continue and cool off step-down and refrigerant evaporation absorption stroke, and freeze simultaneously, and then reach the effect that reduces the system standby time with another sub-vacuum chamber 31 or 32.
