Referring to fig. 1, an embodiment of the present disclosure provides a temperature adjustment system including a refrigerant circulation circuit 300 and a water circulation circuit 400. The refrigerant circulation circuit 300 is formed by sequentially connecting a compressor 310, an outdoor heat exchanger 320, a throttle device 330, and an indoor heat exchanger 340 through pipes. The water circulation loop 400 includes an outdoor liquid storage device 410 disposed in parallel with the outdoor heat exchanger 320 and an indoor liquid storage device 420 disposed in parallel with the indoor heat exchanger 340. The water outlet end of the outdoor heat exchanger 320 is connected to the first inflow end of the outdoor liquid storage device 410 through the outdoor water supply pump 430, and the water inlet end is connected to the outflow end of the outdoor liquid storage device 410. The water outlet end of the outdoor heat exchanger 320 and the refrigerant inflow end are located at the same side, and the water inlet end of the outdoor heat exchanger 320 and the refrigerant outflow end are located at the same side. The water outlet end of the indoor heat exchanger 340 is connected to the first inflow end of the indoor liquid storage device 420 through the indoor water supply pump 440, and the water inlet end is connected to the outflow end of the indoor liquid storage device 420. Wherein, the water outlet end and the refrigerant inflow end of the indoor heat exchanger 340 are positioned at the same side, and the water inlet end and the refrigerant outflow end of the indoor heat exchanger 340 are positioned at the same side. The indoor water supply pump 440 is provided with a heat radiating part 450 between the indoor liquid storage devices 420, and the heat radiating part 450 includes a plurality of fan coils 451 arranged in parallel. The second inflow end of the outdoor liquid storage device 410 and the second inflow end of the indoor liquid storage device 420 are connected through a pipe, and a water supplementing valve 460 for connecting an external water source is provided. An indoor water supplementing pump 470 is arranged between the water supplementing valve 460 and the indoor liquid storage device 420, and an outdoor water supplementing pump 480 is arranged between the water supplementing valve 460 and the outdoor liquid storage device 410. A water mixing valve 490 is arranged between the water supplementing valve 460 and the outdoor water supplementing pump 480, and the water mixing valve 490 is further connected between the heat dissipating part 450 and the indoor liquid storage device 420 through a pipeline so as to connect the outflow end of the heat dissipating part 450 and the second inflow end of the outdoor liquid storage device 410 for water mixing. In addition, the temperature control system further includes a processor electrically connected to the elements of the outdoor heat exchanger 320, the indoor heat exchanger 340, the water replenishment valve 460, the water mixing valve 490, the indoor water replenishment pump 470, the outdoor water replenishment pump 480, the indoor water supply pump 440, and the outdoor water supply pump 430, for controlling the operation of the components in the system. The indoor heat exchanger 340 and the outdoor heat exchanger 320 may be double pipe heat exchangers, plate heat exchangers, or other heat exchangers capable of realizing water-fluorine heat exchange, which are not particularly limited herein.

Specifically, in the case of the temperature control system operating in the cooling mode, the high-temperature and high-pressure refrigerant in the refrigerant circulation circuit 300 is compressed by the compressor 310, and then flows into the outdoor heat exchanger 320 through the four-way valve to perform water-fluorine heat exchange. And then the refrigerant flows into the indoor heat exchanger 340 for water-fluorine heat exchange after the throttling function of the electronic expansion valve. The final low-temperature low-pressure refrigerant flows into the gas-liquid separator through the four-way valve and then flows back to the compressor 310. In the water circulation loop 400, the outdoor water supply pump 430 is turned on, so that water in the outdoor liquid storage device 410 flows from the water inlet end of the outdoor heat exchanger 320 to the water outlet end of the outdoor heat exchanger 320, and then flows back into the outdoor liquid storage device 410 through the outdoor water supply pump 430. At this time, the waterway heat exchange of the outdoor heat exchanger 320 completes one cycle. Since the outdoor heat exchanger 320 is located at the high temperature and high pressure side in the cooling mode, the water temperature in the outdoor liquid storage device 410 may be gradually increased as the number of cycles increases. For the indoor heat exchanger 340, the indoor water supply pump 440 is turned on, the temperature of the water in the indoor liquid storage device 420 is reduced after the water is subjected to heat exchange by the indoor heat exchanger 340, and then the air in the action range of the temperature adjusting system is reduced by the heat radiating part 450, and finally the water flows back to the indoor liquid storage device 420. At this time, the waterway heat exchange of the indoor heat exchanger 340 completes one cycle. Although the water flowing back into the indoor reservoir 420 may be at a higher temperature than when it is flowing out, it is still much lower than the water temperature in the outdoor reservoir 410. Under the condition that the temperature control system operates in a heating mode, the high-temperature and high-pressure refrigerant in the refrigerant circulation loop 300 is compressed by the compressor 310, and then flows into the indoor heat exchanger 340 through the four-way valve to perform water-fluorine heat exchange. The final low-temperature low-pressure refrigerant flows into the gas-liquid separator through the four-way valve and then flows back to the compressor 310. In the water circulation circuit 400, the outdoor water supply pump 430 is turned on to operate the waterway heat exchange cycle of the outdoor heat exchanger 320. Since the outdoor heat exchanger 320 is located at the low temperature and low pressure side in the heating mode, the water temperature in the outdoor liquid storage device 410 is gradually lowered as the number of cycles increases. In the heating mode, the indoor heat exchanger 340 is located at the high temperature and high pressure side. The indoor water supply pump 440 is turned on, the temperature of the water in the indoor liquid storage device 420 is reduced after the water is subjected to heat exchange by the indoor heat exchanger 340, then the temperature of the air in the action range of the temperature adjusting system is increased by the heat radiating part 450, and finally the water flows back to the indoor liquid storage device 420 to complete one cycle. Although the water flowing back into the indoor reservoir 420 may be at a lower temperature than when it is flowing out, it is still much higher than the water temperature in the outdoor reservoir 410. Therefore, the heat exchange channel is established between the two heat exchangers, so that the energy consumption of the temperature regulating system is reduced.

In connection with the attemperation system shown in FIG. 1, embodiments of the present disclosure provide a method for controlling an attemperation system. As shown in fig. 2, the method includes:

s01, the processor acquires the water temperature value in the outdoor liquid storage equipment.

S02, the processor determines corresponding preset conditions according to the operation mode of the air conditioner.

S03, the processor controls the running state of the water circulation loop according to the water temperature value and preset conditions.

By adopting the method for controlling the temperature regulating system, which is provided by the embodiment of the disclosure, whether the heat exchange efficiency of the current outdoor heat exchanger can meet the use requirement can be determined by detecting the water temperature value in the outdoor liquid storage equipment for heat exchange with the outdoor heat exchanger. And determining a preset judging condition corresponding to the current operation mode through different operation modes of the air conditioner. And judging whether the heat exchange efficiency of the current outdoor heat exchanger can meet the use requirement in the operation mode or not according to the water temperature value and preset conditions. Thereby adjusting different water pumps and valves and adjusting the water temperature in the outdoor liquid storage equipment. And then the heat exchange efficiency of the outdoor heat exchanger is regulated so as to ensure the temperature regulation efficiency of the temperature regulation system.

Optionally, the processor controls the operation state of the water circulation loop according to the water temperature value and a preset condition, including: and under the condition that the water temperature value meets a first preset condition, the processor controls the water mixing valve to be opened. The processor controls the outdoor water supplementing pump to start and operate.

Thus, the temperature adjusting efficiency of the temperature adjusting system can be better ensured. Under the condition that the water temperature value meets a first preset condition, the fact that the water temperature in the current outdoor liquid storage equipment cannot meet the heat exchange requirement of the heat exchanger is judged. Therefore, the water mixing valve is opened, so that after the outdoor liquid storage equipment and the water subjected to temperature adjustment by the indoor heat exchanger are interacted, the water temperature adjustment of the outdoor liquid storage equipment is realized without additional energy consumption. Specifically, under the condition that the temperature regulating system operates in a refrigeration mode, when the water temperature value is larger than a first high-temperature threshold value, the current water temperature value is judged to meet a first preset condition, namely the current system is in a high-pressure operation state and is not beneficial to heat dissipation of the outdoor heat exchanger. At this time, the processor controls the water mixing valve to open and starts the outdoor water supplementing pump. Because the water temperature flowing through the heat dissipation part is lower at this moment, the water temperature mixed by the water mixing valve is also lower, so that the water temperature in the outdoor liquid storage equipment is gradually reduced. Therefore, the pressure of the temperature regulating system can be reduced, and the heat exchange effect of the outdoor heat exchanger can be improved, so that the refrigerating effect of the whole system is improved. The range of the first high temperature threshold value can be any value in [47, 53] °c. Preferably, it may be 49 ℃, 50 ℃ or 52 ℃. Under the condition that the temperature regulating system operates in a heating mode, when the water temperature value is smaller than a first low-temperature threshold value, the current water temperature value is judged to meet a first preset condition, namely the current system is in a low-pressure operation state and is not beneficial to heat dissipation of the outdoor heat exchanger. At this time, the processor controls the water mixing valve to open and starts the outdoor water supplementing pump. Because the water temperature flowing through the heat dissipation part is higher at this moment, the water temperature mixed by the water mixing valve is also higher, so that the water temperature in the outdoor liquid storage equipment is gradually increased. Therefore, the pressure of the temperature regulating system can be increased, and the heat exchange effect of the outdoor heat exchanger can be improved, so that the heating effect of the whole system is improved. The range of the first low temperature threshold value can be any value in [2,7] °c. Preferably, it may be 3 ℃, 5 ℃ or 6 ℃.

As shown in connection with fig. 3, an embodiment of the present disclosure provides another method for controlling a temperature regulating system, comprising:

s01, the processor acquires the water temperature value in the outdoor liquid storage equipment.

S02, the processor determines corresponding preset conditions according to the operation mode of the air conditioner.

S041, after controlling the water mixing valve to be opened, the processor obtains the water quantity value of the indoor liquid storage equipment.

And S042, controlling the water supplementing valve to be opened by the processor under the condition that the water quantity value is smaller than or equal to the first water quantity threshold value.

S043, the processor controls the indoor water supplementing pump to start to operate.

By adopting the method for controlling the temperature regulating system, which is provided by the embodiment of the disclosure, the influence on the temperature regulating efficiency of the temperature regulating system due to insufficient water quantity in the liquid storage device can be avoided. Because the interaction between the indoor liquid storage equipment and the indoor heat exchanger is closed circulation and the conveying pipeline is long, the influence of water evaporation on the temperature adjustment efficiency is considered. Therefore, the water quantity value of the indoor liquid storage equipment is monitored in real time, and under the condition that the water quantity value is smaller than or equal to the first water quantity threshold value, the current water quantity is considered to be insufficient to meet the working requirement of the temperature regulating system. At this time, the water supplementing valve and the indoor water supplementing pump are controlled to be opened, and the water quantity in the indoor liquid storage equipment is timely supplemented through an external water source.

As shown in connection with fig. 4, an embodiment of the present disclosure provides another method for controlling a temperature regulating system, comprising:

s01, the processor acquires the water temperature value in the outdoor liquid storage equipment.

S02, the processor determines corresponding preset conditions according to the operation mode of the air conditioner.

And S051, after the outdoor water supplementing pump is controlled to be started, the processor acquires the water temperature value in the outdoor liquid storage equipment again.

S052, under the condition that the water temperature value meets a second preset condition, the processor controls the water mixing valve to be closed.

S053, the processor controls the outdoor water supplementing pump to stop running.

By adopting the method for controlling the temperature regulating system, which is provided by the embodiment of the disclosure, the operation of the water pump can be closed in time so as to reduce the energy consumption of the system. Under the condition that the water temperature value meets the second preset condition, the current water temperature value is judged to meet the second preset condition, namely the water temperature in the current outdoor liquid storage equipment is enough to meet the heat exchange requirement of the heat exchanger. At this time, the water temperature is adjusted without interaction between the outdoor liquid storage device and the water after the temperature is adjusted by the indoor heat exchanger, so that the water mixing valve and the outdoor water supplementing pump can be controlled to be closed, and unnecessary energy consumption is avoided. Specifically, under the condition that the temperature regulating system operates in the refrigeration mode, when the water temperature value is smaller than the second high temperature threshold value, the current water temperature value is judged to meet the second preset condition, namely the water temperature in the outdoor liquid storage equipment is enough to meet the heat exchange requirement of the heat exchanger. At this time, the processor controls the water mixing valve to close and shuts off the outdoor water supplementing pump. The range of the second high temperature threshold value can be any value in [38, 43] °c. Preferably, it may be 39 ℃, 40 ℃ or 41 ℃. Under the condition that the temperature regulating system operates in a refrigerating mode, when the water temperature value is larger than a second low-temperature threshold value, the water temperature in the outdoor liquid storage equipment is judged to be enough to meet the heat exchange requirement of the heat exchanger. At this time, the processor controls the water mixing valve to close and shuts off the outdoor water supplementing pump. The range of the second low temperature threshold value can be any value of [8, 12] °c. Preferably, it may be 9 ℃, 10 ℃ or 11 ℃.

As shown in connection with fig. 5, an embodiment of the present disclosure provides another method for controlling a temperature regulating system, comprising:

s01, the processor acquires the water temperature value in the outdoor liquid storage equipment.

S02, the processor determines corresponding preset conditions according to the operation mode of the air conditioner.

And S061, after controlling the water mixing valve to be opened, the processor determines the outdoor operation power of the outdoor water supply pump and the indoor operation power of the indoor water supply pump according to the water temperature value.

And S062, the processor controls the outdoor water supply pump to operate with the outdoor operation power.

And S063, the processor controls the indoor water supply pump to operate at the indoor operation power.

By adopting the method for controlling the temperature regulating system, provided by the embodiment of the disclosure, the running state of the system can be timely regulated according to the actual use requirement, so that unnecessary energy consumption is avoided. The required water temperature value is also different according to the temperature adjustment requirements. Therefore, according to the target temperature and the current water temperature value, the outdoor operation power of the optimal outdoor water supply pump and the indoor operation power of the indoor water supply pump which can meet the temperature regulation requirement at present can be obtained through the preset corresponding relation. By controlling the operation power of the outdoor water supply pump and the indoor water supply pump, the operation power can be effectively adapted to the required flow speed, and unnecessary energy consumption is avoided.

As shown in connection with fig. 6, an embodiment of the present disclosure provides another method for controlling a temperature regulating system, comprising:

s01, the processor acquires the water temperature value in the outdoor liquid storage equipment.

S02, the processor determines corresponding preset conditions according to the operation mode of the air conditioner.

And S071, after the outdoor water supplementing pump is controlled to be started, the processor acquires the water quantity value of the outdoor liquid storage equipment.

And S072, controlling the water supplementing valve to be opened by the processor under the condition that the water quantity value is smaller than or equal to the second water quantity threshold value.

By adopting the method for controlling the temperature regulating system, which is provided by the embodiment of the disclosure, the influence on the temperature regulating efficiency of the temperature regulating system due to insufficient water quantity in the outdoor liquid storage device can be avoided. Because the interaction between the outdoor liquid storage equipment and the outdoor heat exchanger is closed circulation, the influence of the evaporation of water on the temperature adjustment efficiency is considered. Therefore, the water quantity value of the outdoor liquid storage equipment is monitored in real time, and under the condition that the water quantity value is smaller than or equal to the second water quantity threshold value, the current water quantity is considered to be insufficient to meet the working requirement of the temperature regulating system. At this time, the water replenishing valve and the outdoor water replenishing pump are controlled to be opened, and the water quantity in the outdoor liquid storage equipment is timely replenished through an external water source. The first water amount threshold and the second water amount threshold are only used for illustration, and have no clear size relationship, and the actual value depends on the use requirement. When the outdoor liquid storage equipment and the indoor liquid storage equipment have the problem of insufficient water quantity, a mode of only supplementing water to one of the outdoor liquid storage equipment or the indoor liquid storage equipment or a mode of simultaneously supplementing water to the outdoor liquid storage equipment and the indoor liquid storage equipment can be adopted according to the degree of water quantity requirements.

Optionally, the processor obtains an ambient temperature within the range of action of the tempering system. The processor determines a target rotational speed of the blower based on the ambient temperature. The processor controls the fan to operate at a target rotational speed.

Therefore, the temperature adjusting efficiency of the temperature adjusting device can be better adjusted in an auxiliary mode through adjusting the rotating speed of the fan. When the temperature regulation requirement of the temperature regulation system is still difficult to meet after the interaction of the outdoor liquid storage equipment and the indoor heat exchanger, the reasonable target rotating speed of the fan can be determined according to the preset corresponding relation by acquiring the ambient temperature in the action range of the temperature regulation system. Therefore, the defect that only a heat exchange mode is adopted can be overcome by adjusting the rotating speed of the fan. In addition, the reasonable target rotating speed of the fan can be determined according to the environment temperature through a preset corresponding relation, so that the running power of each water pump can be considered, and the energy consumption of the temperature regulating system can be reduced.
