The following describes various operation modes of the multi-cold-source triple co-generation unit 1.
Referring to fig. 2, fig. 2 is a schematic diagram illustrating the multi-heat-source triple co-generation unit 1 provided in the embodiment of the present application operating in a first circuit, wherein arrows indicate the flowing direction of the refrigerant.
When the first four-way valve 610 is de-energized and the second four-way valve 620 is energized, the first switching valve 630 conducts the second passage 720, and the second switching valve 640 conducts the air-conditioning water heat exchange passage 400. And the water-cooling heat exchange passage 100 and the air-cooling heat exchange passage 200 are closed by other on-off valves, that is, the third on-off valve 650 closes the water-cooling heat exchange passage 100, and the fourth on-off valve 660 closes the air-cooling heat exchange passage 200. At this time, the refrigerant is output through the output end 11 after being compressed by the compressor 10, and passes through the second passage 720, the second four-way valve 620, the evaporative cooling and heat exchange passage 300, the second one-way passage 530, the throttle pipe 510, the third one-way passage 540, the fifth one-way passage 560, the air-conditioning water heat exchange passage 400, and the first four-way valve 610 in sequence, and then returns to the compressor 10 through the liquid return end 12 to form a first circuit. When the multi-cold-source triple co-generation unit 1 runs the first loop, the high-temperature and high-pressure refrigerant is cooled by the evaporative cooling heat exchange passage 300 and is depressurized by the throttling passage 500 to form a low-temperature and low-pressure refrigerant, the low-temperature and low-pressure refrigerant enters the air-conditioning water heat exchange passage 400, and the air-conditioning water heat exchange passage 400 can output refrigerating capacity to a specified area. At this time, the multi-cold source triple co-generation unit 1 is in the single refrigeration mode when operating the first loop.
Referring to fig. 3, fig. 3 is a schematic diagram illustrating the multi-heat-source triple co-generation unit 1 provided in the embodiment of the present application operating in a second circuit, wherein arrows indicate the flowing direction of the refrigerant.
When the first four-way valve 610 is powered off and the second four-way valve 620 is powered on, the first switch valve 630 conducts the second passage 720, the second switch valve 640 conducts the air-conditioning water heat exchange passage 400, and the third switch valve 650 conducts the water-cooling heat exchange passage 100. The air-cooling heat exchange path 200 is closed by the other on-off valve, that is, the air-cooling heat exchange path 200 is closed by the fourth on-off valve 660. At this time, the refrigerant is output through the output terminal 11 after being compressed by the compressor 10, and after the compressor 10 outputs the refrigerant, a part of the refrigerant flows into the second passage 720, and another part of the refrigerant flows into the water-cooled heat exchange passage 100. At this time, the water-cooling heat exchange passage 100 is controlled to work, so that the water in the water-cooling heat exchange passage 100 can be heated by the refrigerant, and hot water for daily use of a user can be provided. After flowing through the water-cooled heat exchange passage 100, the refrigerant is guided to the first passage 710 by the first four-way valve 610, and the first passage 710 collects the refrigerant in the second passage 720. The second path 720 directs the refrigerant to the second four-way valve 620, and then the refrigerant passes through the evaporation-cooling heat exchange path 300, the second one-way path 530, the throttle pipe 510, the third one-way path 540, the fifth one-way path 560, the air-conditioning water heat exchange path 400, and the first four-way valve 610 in this order, and then returns to the compressor 10 through the liquid return port 12 to form a second circuit. When the multi-cold-source triple co-generation unit 1 operates the second loop, part of the high-temperature and high-pressure refrigerant flows into the water-cooling heat exchange passage 100 to heat water in the water-cooling heat exchange passage 100. In addition, the refrigerant can be cooled through the evaporative cooling heat exchange passage 300 and the throttling mechanism, so that the cooled refrigerant flows through the air-conditioning water heat exchange passage 400, and the purpose that the air-conditioning water heat exchange passage 400 outputs the refrigerating capacity to the designated area is achieved. At this time, the multi-cold source triple co-generation unit 1 is used for operating the second loop in a refrigeration and hot water mode.
It should be noted that, compared to the refrigeration mode when the multi-cold-source triple co-generation unit 1 operates the first loop, in the refrigeration and hot water mode, because the refrigerant is cooled by cold water in the water-cooling heat exchange path 100, the temperature of the refrigerant entering the evaporation cold heat exchange path 300 and the throttling path 500 is relatively lower, so that the refrigeration capacity output by the air-conditioning water heat exchange path 400 can be increased, and the refrigeration effect can be improved.
Referring to fig. 4, fig. 4 is a schematic diagram illustrating the multi-cold-source triple co-generation unit 1 provided in the embodiment of the present application operating in a third circuit, wherein arrows indicate the flowing direction of the refrigerant.
When the first four-way valve 610 is energized and the second four-way valve 620 is energized, the second switching valve 640 conducts the air-conditioning water heat exchange passage 400, the third switching valve 650 conducts the water-cooling heat exchange passage 100, and the fourth switching valve 660 conducts the air-cooling heat exchange passage 200. The other switching valve closes the evaporative cooling heat exchange path 300 and the second path 720, that is, the second path 720 can be closed by the first switching valve 630, and at this time, the evaporative cooling heat exchange path 300 which is in communication with the second path 720 is also closed because the second path 720 is closed. At this time, the refrigerant is output through the output terminal 11 after being compressed by the compressor 10, and sequentially flows through the water-cooling heat exchange path 100, the first four-way valve 610, the air-conditioning water heat exchange path 400, the throttle path 500, the air-cooling heat exchange path 200, and the second four-way valve 620, and then returns to the compressor 10 through the liquid return terminal 12 to form a third circuit.
On the basis, when the working state of the water-cooling heat exchange passage 100 or the working state of the air-conditioning water heat exchange passage 400 is changed, the multi-cold-source triple co-generation unit 1 operates in different modes. On one hand, when the water-cooling heat exchange passage 100 operates and the air-conditioning water heat exchange passage 400 operates, the high-temperature and high-pressure refrigerant heats cold water in the water-cooling heat exchange passage 100 and can output hot water to the outside through the water-cooling heat exchange passage 100; meanwhile, after the refrigerant is cooled by the water-cooling heat exchange passage 100, the refrigerant is in a higher temperature state, and the refrigerant in the higher temperature state flows into the air-conditioning water heat exchange passage 400 and can output heating capacity to a designated area. Subsequently, the refrigerant is returned to the compressor 10 after the throttle mechanism and the pressure and temperature reduction of the air-cooled heat exchange path 200. At this time, the multi-cold-source triple co-generation unit 1 operates the third loop, and the mode in which the water-cooling heat exchange passage 100 operates and the air-conditioning water heat exchange passage 400 operates is the air-cooling heating and hot water mode.
On the other hand, when the water-cooled heat exchange path 100 is not operated and the air-conditioned water heat exchange path 400 is operated, the refrigerant of high temperature and high pressure flows toward the air-conditioned water heat exchange path 400 by the guidance of the water-cooled heat exchange path 100, and the water-cooled heat exchange path 100 does not provide a cooling effect to the refrigerant. At this time, the refrigerant entering the air-conditioning water heat exchange passage 400 is a high-temperature and high-pressure refrigerant, which can provide more heating amount compared to the above-described air-cooling heating and hot-water modes, thereby improving the heating effect. Subsequently, the refrigerant is returned to the compressor 10 after the throttle mechanism and the pressure and temperature reduction of the air-cooled heat exchange path 200. At this time, the multi-cold-source triple co-generation unit 1 operates the third loop, and the mode that the water-cooling heat exchange passage 100 does not work and the air-conditioning water heat exchange passage 400 works is the air-cooling single heating mode.
In yet another aspect, when the water-cooled heat exchange path 100 is operated and the air-conditioned water heat exchange path 400 is not operated, the high-temperature and high-pressure refrigerant enters the inside of the water-cooled heat exchange path 100, thereby heating the cold water in the water-cooled heat exchange path 100, so that the water-cooled heat exchange path 100 can output the hot water to the outside. Meanwhile, since the air-conditioning water heat exchange passage 400 does not operate, the air-conditioning water heat exchange passage 400 provides only a guiding function to the refrigerant at this time, and then, the refrigerant returns to the compressor 10 after the pressure and temperature reduction of the throttling mechanism and the air-cooling heat exchange passage 200. It should be noted that the non-operation of the air-conditioning water heat exchange passage 400 means that in the air-conditioning water heat exchange passage 400, the refrigerant in the pipeline stops flowing, so that the refrigerant cannot output the heating amount provided by the refrigerant to the inside of the designated area. At this time, the multi-cold-source triple co-generation unit 1 operates the third loop, and the mode in which the water-cooling heat exchange passage 100 operates and the air-conditioning water heat exchange passage 400 does not operate is the air-cooling water heating mode.
Referring to fig. 5, fig. 5 is a schematic diagram illustrating the multi-cold-source triple co-generation unit 1 provided in the embodiment of the present application operating in a fourth circuit, wherein arrows indicate the flowing direction of the refrigerant.
When the second four-way valve 620 is powered off, the first switch valve 630 is connected to the second passage 720, and the fourth switch valve 660 is connected to the air-cooling heat exchange passage 200. And the other switching valves close the water-cooling heat exchange passage 100 and the air-conditioning water heat exchange passage 400, i.e., the second switching valve 640 closes the air-conditioning water heat exchange passage 400, and the third switching valve 650 closes the water-cooling heat exchange passage 100. At this time, the refrigerant is compressed by the compressor 10, then outputted from the output terminal 11, and sequentially flows through the second passage 720, the second four-way valve 620, the air-cooled heat exchange passage 200, the fifth one-way passage 560, the fourth one-way passage 550, the throttle pipe 510, the first one-way passage 520, the evaporative cooling heat exchange passage 300, and the second four-way valve 620, and then returns to the compressor 10 through the liquid return terminal 12, thereby forming a fourth circuit. At this time, the high-temperature and high-pressure refrigerant enters the air-cooled heat exchange path 200, and can provide a defrosting effect to the air-cooled heat exchanger 220, so that the problem of defrosting of the air-cooled heat exchange path 200 can be solved. At this time, the defrosting mode is adopted when the multi-cold-source triple co-generation unit 1 operates the fourth loop.
Referring to fig. 6, fig. 6 is a schematic diagram illustrating the multi-cold-source triple co-generation unit 1 provided in the embodiment of the present application operating in a fifth loop, wherein arrows indicate a flow direction of the refrigerant.
When the second four-way valve 620 is powered off and the first four-way valve 610 is powered on, the first switch valve 630 conducts the second passage 720, the fourth switch valve 660 conducts the air-cooling heat exchange passage 200, the second switch valve 640 conducts the air-conditioning water heat exchange passage 400, and the third switch valve 650 conducts the water-cooling heat exchange passage 100. At this time, after the high-temperature and high-pressure refrigerant is output from the output terminal 11, a part of the refrigerant sequentially flows through the water-cooling heat exchange passage 100, the first four-way valve 610 and the air-conditioning water heat exchange passage 400, and is then introduced into the fourth one-way passage 550; another part of the refrigerant passes through the second path 720, the second four-way valve 620, the air-cooled heat exchange path 200, and the fifth one-way path 560 in sequence, and then is introduced into the fourth one-way path 550. That is, two portions of the refrigerant are merged in the fourth one-way passage 550, and sequentially flow through the fourth one-way passage 550, the throttle pipe 510, the first one-way passage 520, the evaporation-cooling heat exchange passage 300, and the second four-way valve 620, and then are guided to the compressor 10 from the liquid return end 12 to form the fifth circuit.
On the basis, when the working state of the water-cooling heat exchange passage 100 or the working state of the air-conditioning water heat exchange passage 400 is changed, the multi-cold-source triple co-generation unit 1 operates in different modes. In one aspect, when the water-cooled heat exchange passage 100 is not operated and the air-conditioned water heat exchange passage 400 is operated, the water-cooled heat exchange passage 100 provides a guiding function to the refrigerant, thereby allowing a portion of the high-temperature and high-pressure refrigerant led out from the output terminal 11 to be guided into the air-conditioned water heat exchange passage 400. The air-conditioning water heat exchange passage 400 can output heating power to a designated area after receiving the high-temperature and high-pressure refrigerant. At this time, the multi-cold-source triple co-generation unit 1 operates the fifth loop, and the mode in which the water-cooling heat exchange passage 100 does not operate and the air-conditioning water heat exchange passage 400 operates is the heating and defrosting mode. On the other hand, when the water-cooling heat exchange path 100 is operated and the air-conditioning water heat exchange path 400 is not operated, the refrigerant with high temperature and high pressure can provide a heating effect to the cold water in the water-cooling heat exchange path 100 when entering the water-cooling heat exchange path 100, thereby achieving the purpose of providing domestic hot water to the user. In addition, since the air-conditioning water heat exchange passage 400 does not operate, at this time, the air-conditioning water heat exchange passage 400 provides only a guiding function to the refrigerant. That is, the fifth circuit is operated by the multi-cold-source triple co-generation unit 1, and the state in which the water-cooling heat exchange passage 100 does not operate and the air-conditioning water heat exchange passage 400 operates is the heating water and defrosting mode.
It should be noted that, in the embodiment of the present application, the multiple cold source triple co-generation unit 1 can select an adaptive mode to operate according to an actual situation, so as to improve the energy efficiency of the multiple cold source triple co-generation unit 1. For example, when the designated area needs to be refrigerated, the multi-cold-source triple co-generation unit 1 can perform refrigeration by operating the single refrigeration mode, so as to output the refrigeration capacity to the designated area. When the refrigerating output is not enough to satisfy user's demand when the single mode of refrigeration of operation, many cold sources trigeminy supplies unit 1 can operate refrigeration and hot water mode this moment, can not only promote refrigeration efficiency this moment, and can also provide domestic hot water to the user simultaneously. In addition, when the designated area needs to be heated, at this time, the multi-cold-source triple co-generation unit 1 can operate an air cooling heating and hot water mode, and further can provide domestic water for the user while outputting the heating quantity to the designated area. When the heating quantity output by the air cooling heating and hot water running mode is not enough to meet the requirements of users, the multi-cold-source triple co-generation unit 1 can run the air cooling single heating mode at the moment, and then the heating quantity output by the multi-cold-source triple co-generation unit 1 to a specified area can be improved, and further the heating efficiency is improved. When the designated area does not need to be heated, the air cooling hot water making mode can be operated, and then the multi-cold source triple co-generation unit 1 can provide domestic hot water for users. Further, when frosting is formed on the air-cooled heat exchanger 220 in the air-cooled heat exchange path 200, the multiple cold source triple co-generation unit 1 can operate in the defrosting mode, so that a defrosting effect can be provided for the air-cooled heat exchanger 220, defrosting on the air-cooled heat exchanger 220 is melted, and normal operation of the air-cooled heat exchange path 200 in other modes can be guaranteed. Frosting on air cooled heat exchanger 220 to when appointed region need heat simultaneously, many cold sources trigeminy supplies unit 1 can operate defrosting and heat the mode this moment, and then can provide the effect of heating in to appointed region in the defrosting, and then can ensure many cold sources trigeminy supplies unit 1 to provide good effect of heating to appointed region in many trigeminy supplies unit 1 when the defrosting, solve among the prior art can not carry out effectual effect of heating and cause the problem that the comfort level reduces to the user in the defrosting simultaneously.
