The following describes an air conditioning system, a control method thereof and a control device thereof according to the present invention with reference to the accompanying drawings, and it should be noted that the control method and the control device according to the present invention are implemented based on the air conditioning system according to the present invention.
As shown in fig. 1 to 3, the air conditioning system according to the embodiment of the first aspect of the present invention includes an electric control device 4, a refrigerant system, and a water heat exchange system.
The refrigerant system comprises a compressor 1, an indoor heat exchanger 2, an outdoor heat exchanger 3 and a first expansion valve 11 which are mutually connected through refrigerant pipelines, and an electric control device 4 is respectively and electrically connected with the compressor 1 and the first expansion valve 11.
The water heat exchange system is respectively and thermally coupled with the indoor heat exchanger 2 and the electric control device 4, and an adjustable second expansion valve 61 is arranged in the water heat exchange system.
According to the air conditioning system of the embodiment of the invention, as the water heat exchange system is respectively and thermally coupled with the indoor heat exchanger 2 and the electric control device 4, the water heat exchange system can generate different beneficial effects by respectively exchanging heat with the indoor heat exchanger 2 and the electric control device 4, and the specific description is as follows:
On the one hand, for the electronic control device 4: in the operation process of the refrigerant system, the electric control device 4 can generate more heat, at this time, because the water heat exchange system is thermally coupled with the electric control device 4, under the condition that the electric control device 4 is overheated, the cooling water in the water heat exchange system can take away the redundant waste heat in the electric control device 4 to play the role of cooling the electric control device 4, thereby ensuring the stable operation of the electric control device 4, ensuring the service life of the electric control device 4, and improving the refrigeration and heating efficiency of the air conditioning system and the use experience of users.
On the other hand, for the indoor heat exchanger 2: under different working modes of the air conditioning system, the water heat exchange system can have different heat exchange effects on the indoor heat exchanger 2.
In some embodiments, when the air conditioning system is in the cooling mode, the water heat exchange system may absorb the excessive cold energy in the indoor heat exchanger 2 through the cooling water and transmit the cold energy to the electric control device 4, so that the electric control device 4 is cooled by using the cold energy of the indoor heat exchanger 2, thereby realizing effective utilization of the excessive cold energy of the indoor heat exchanger 2 and preventing the electric control device 4 from overheat operation.
In other embodiments, when the air conditioning system is turned on for heating and before the air conditioning system is not stabilized into heating operation, the temperature of the indoor heat exchanger 2 is still low at this time although the electric control device 4 is operated to generate excessive heat, so that the water heat exchange system can absorb and transfer the heat in the electric control device 4 to the indoor heat exchanger 2 through the cooling water to assist in heating, thereby helping the indoor heat exchanger 2 to reach the target heating temperature more quickly. Further, when the indoor heat exchanger 2 has reached the target heating temperature or the temperature of the indoor heat exchanger 2 has exceeded the temperature of the cooling water in the water heat exchange system, the water heat exchange system will short-circuit the indoor heat exchanger 2 and transfer the heat absorbed by the cooling water to the heat storage water tank 81 and other devices, so as to realize the reuse of the waste heat in the electric control device 4.
In the related art, the most important function for air conditioning is to adjust indoor temperature for comfort. However, because of the excessively high air temperature or the narrow installation space, the heat exchange of the outdoor air-cooled condensing heat exchange air conditioner of the unit is poor, the system pressure of the unit is increased, and because of the high outdoor environment temperature and the large unit load, the temperature rise of the electric control board of the unit can become excessively high. In order to protect the normal operation of the electric control board of the unit, the operation frequency of the compressor needs to be limited, and even the operation frequency of the compressor is reduced, so that the operation can influence the refrigerating capacity of the unit under the condition of high temperature or dirt on the fins of the condenser, and the refrigerating capacity is reduced, so that the comfort is reduced.
Accordingly, in order to solve the technical drawbacks of the related art, the present invention provides an air conditioning system having at least the following advantages compared to the related art:
(1) Energy efficiency promotes: the waste heat generated by the refrigerant system can be more effectively utilized through the thermal coupling of the water heat exchange system with the electric control device 4 and the indoor heat exchanger 2. In the cooling mode, the surplus cold can be used to cool the electric control device 4, while in the heating mode, the heat generated by the electric control device 4 can assist the indoor heat exchanger 2 to heat up quickly, which reduces the consumption of additional energy.
(2) And (3) temperature control optimization: the water heat exchange system can intelligently adjust the second expansion valve 61 according to the actual temperature and the requirements of the indoor and outdoor heat exchangers, so that more accurate temperature control is realized. This not only improves the comfort of the user, but also contributes to a stable operation of the system.
(3) The service life of the equipment is prolonged: the heat generated by the electronic control unit 4 during operation may, if not effectively controlled, cause the device to overheat, affecting its performance and lifetime. The scheme cools the electric control device 4 through the water heat exchange system, which is helpful for reducing the working temperature of the electric control device, thereby prolonging the service life of the equipment.
(4) Environmental protection: this solution helps to reduce the impact on the environment by improving energy efficiency and reducing waste heat emissions. In addition, the reuse of waste heat also accords with the principle of sustainable development.
(5) Multifunction: the system not only can provide refrigeration and heating functions, but also can realize different heat exchange effects under different working modes, and can automatically adjust the working modes according to indoor and outdoor temperature changes and user requirements, so that the air conditioning system can adapt to various different environmental conditions, and the flexibility and adaptability of the system are improved.
(6) The system integration level is high: the electric control device 4, the refrigerant system and the water heat exchange system are integrated, so that the design of the air conditioning system is simplified, the complexity of external connection and maintenance is reduced, and the reliability of the system is improved.
As shown in fig. 1 to 3, according to some embodiments of the present invention, the water heat exchange system includes a water heat exchange circuit 5, the water heat exchange circuit 5 flows through the indoor heat exchanger 2, a first heat exchange water pipe 6 is disposed on the water heat exchange circuit 5, the first heat exchange water pipe 6 flows through the electric control device 4, both ends of the first heat exchange water pipe 6 are connected to the water heat exchange circuit 5, and a second expansion valve 61 is disposed on the first heat exchange water pipe 6.
In the present embodiment, the water heat exchange circuit 5 is a closed circulation system in which cooling water or hot water flows, and the circuit flows through the indoor heat exchanger 2 to exchange heat with the indoor heat exchanger 2 through the cooling water or hot water inside. The first heat exchange water pipe 6 flows through the electric control device 4 to take away heat, so that the electric control device 4 is cooled. Both ends of the first heat exchange water pipe 6 are connected with the water heat exchange loop 5 to form a closed pipeline system.
The second expansion valve 61 is mounted on the first heat exchange water pipe 6 for regulating the flow of cooling water through the electronic control device 4. By adjusting the valve, the speed and the quantity of heat of the cooling water carrying the electric control device 4 can be controlled, so that the temperature of the electric control device 4 can be accurately controlled.
It will be appreciated that in the cooling mode, when the electric control device 4 generates heat, the second expansion valve 61 will regulate the flow of cooling water so that the cooling water will carry away excess heat, keeping the electric control device 4 operating at a suitable temperature while the cooling water will be cooled by its internal coolant as it passes through the indoor heat exchanger 2, in preparation for the next cooling cycle. When the heating mode is just entered, the second expansion valve 61 is also opened, and the waste heat generated in the electric control device 4 is carried by the water and is assisted to be heated when flowing through the indoor heat exchanger 2, thereby helping the indoor heat exchanger 2 to quickly reach the target heating temperature.
In this way, by precisely controlling the second expansion valve 61, the heat generated by the electric control device 4 can be effectively taken away through the water heat exchange system, the equipment is kept cool, and the system stability and efficiency are improved. In addition, the water heat exchange system can adjust the flow of cooling water according to actual needs, so that the temperature control of the indoor heat exchanger 2 and the electric control device 4 is more flexible and accurate.
As shown in fig. 2 and 3, according to some embodiments of the present invention, the water heat exchange system further includes a second heat exchange water pipe 7, wherein the second heat exchange water pipe 7 flows through the body of the compressor 1 and both ends thereof are connected to the water heat exchange circuit 5, and a third expansion valve 71 is disposed on the second heat exchange water pipe 7. The cooling water in the second heat exchange water pipe 7 can take away heat generated in the operation process of the compressor 1, so that the stable operation of the compressor 1 is ensured.
The second heat exchange water pipe 7 flows through the body of the compressor 1. Similar to the first heat exchange water pipe 6, two ends of the second heat exchange water pipe 7 are also communicated with the water heat exchange loop 5, so that a closed cooling water circulation is formed. The third expansion valve 71 is used to regulate the flow of cooling water through the compressor 1, and by controlling this valve, the rate and amount of heat carried away by the cooling water from the compressor 1 can be precisely controlled.
It will be appreciated that during operation of the compressor 1, a significant amount of heat is generated due to its operating characteristics. The cooling water in the second heat exchange water pipe 7 absorbs the heat by flowing through the compressor 1, and transfers the heat back to the heat exchange circuit 5 by the adjustment of the third expansion valve 71. In this way, the temperature of the compressor 1 is effectively controlled, ensuring its stable operation.
Further, in the refrigeration mode, the heat of the compressor 1 can be eliminated by the redundant cold energy of the indoor heat exchanger 2, so that the cooling water is ensured to smoothly perform the next cooling cycle; and when the air conditioner is in the heating mode, the heat of the compressor 1 can be used for auxiliary heating of the indoor heat exchanger 2, so that the indoor heat exchanger 2 is helped to quickly reach the target heating temperature, in addition, when the air conditioner is in the stable operation heating mode, the water heat exchange loop 5 is short-circuited to the indoor heat exchanger 2, and at the moment, the heat of the compressor 1 can be used for domestic water and the like, so that the effective utilization of waste heat is realized.
In this way, by the design of the second heat exchange water pipe 7 and the third expansion valve 71, heat generated by the compressor 1 can be effectively taken away, and the compressor 1 is prevented from overheating, thereby protecting the compressor 1 and prolonging the service life thereof. In addition, with the above design to ensure that the compressor 1 operates at a proper temperature, the working efficiency thereof can be improved, thereby improving the cooling or heating efficiency of the entire air conditioning system.
As shown in fig. 3, according to some embodiments of the present invention, the water heat exchange system further includes a third heat exchange water pipe 8, a heat storage water tank 81 is disposed on the third heat exchange water pipe 8, two ends of the third heat exchange water pipe 8 are connected to the water heat exchange circuit 5, and a fourth expansion valve 82 is disposed on the third heat exchange water pipe 8.
The water heat exchange circuit 5 is provided with a short-circuit water pipe 9 connected with the indoor heat exchanger 2 in parallel, and the short-circuit water pipe 9 is provided with a fifth expansion valve 91.
In this embodiment, the short-circuit water pipe 9 is a water pipe connected in parallel with the indoor heat exchanger 2, which provides a path bypassing the indoor heat exchanger 2, and the fifth expansion valve 91 controls the on-off of the short-circuit water pipe 9. In some cases, when the indoor heat exchanger 2 does not need to exchange heat with the water heat exchange system, the fifth expansion valve 91 may be opened, so that the water in the water heat exchange circuit 5 is directly led to other parts (e.g., the heat storage tank 81) through the short-circuit water pipe 9.
It will be appreciated that the fifth expansion valve 91 may be opened during operation of the system when the temperature of the indoor heat exchanger 2 reaches or exceeds a set point, allowing a portion of the water flow to bypass the indoor heat exchanger 2 through the short circuit water line 9 and flow directly to the heat storage tank 81 or other location where heat is required. In this way, the system can quickly respond to indoor temperature changes while controlling heat storage of the thermal storage tank 81 using the fourth expansion valve 82.
Some embodiments of the present invention are described below, in which the structures of the cooling systems in the embodiments described below are the same, but the compositions of the water heat exchange systems are different.

The working process and the working principle of the system are as follows:
In the heating mode, if the temperature of the indoor heat exchanger 2 is lower than the temperature of the electric control device 4 and the temperature of the body of the compressor 1 (for example, when the electric control device 4 just enters heating or when the electric control device is not still stably operating for heating), the second expansion valve 61 and the third expansion valve 71 are both opened, and the fourth expansion valve 82 and the fifth expansion valve 91 are both closed, at this time, the water heat exchange system utilizes the heat of the electric control device 4 and the waste heat of the compressor 1 to perform auxiliary heating on the indoor heat exchanger 2.
In the heating mode, if the temperature of the indoor heat exchanger 2 is higher than the temperature of the electric control device 4 and the temperature of the body of the compressor 1 (for example, the system has stably operated in the heating mode or the indoor heat exchanger 2 has reached the target heating temperature), the second expansion valve 61, the third expansion valve 71, the fourth expansion valve 82 and the fifth expansion valve 91 are opened, at this time, the water heat exchange circuit 5 is short-circuited to the indoor heat exchanger 2 through the short-circuited water pipe 9, and the waste heat of the body of the compressor 1 and the waste heat of the electric control device 4 are transferred to the heat storage water tank 81 through the water circulation circuit for storage, thereby realizing the waste heat recycling on the basis of cooling the compressor 1 and the electric control device 4.

The following describes a control method and a control device for an air conditioning system according to the present invention with reference to the accompanying drawings, where the entire application scenario is described before the embodiments of the present invention are described in detail. The control method, the control device, the electronic equipment and the computer readable storage medium of the air conditioning system can be applied to the local air conditioning system, cloud platforms in the Internet field, cloud platforms in other kinds of Internet fields or third party equipment. The third party device may include a mobile phone, a tablet computer, a notebook computer, a vehicle-mounted computer, and other intelligent terminals.
In the following, a control method applicable to an air conditioning system is merely described as an example, and it should be understood that the control method according to the embodiment of the present invention may also be applicable to a cloud platform and a third party device.
As shown in fig. 4, a control method of an air conditioning system according to an embodiment of a second aspect of the present invention includes:
step S1, determining the current working mode of a refrigerant system and acquiring the temperature of an electric control device 4;
And step S2, controlling and adjusting the working state of the water heat exchange system according to the current working mode and the temperature of the electric control device 4.
According to the control method of the air conditioning system, the specific working process is as follows: the system needs to identify the current working mode of the refrigerant system, namely whether the refrigerant system is in a refrigerating, heating or standby state. At the same time, the system will acquire real-time temperature data of the electronic control device 4. It will be appreciated that the temperature of the electronic control unit 4 is critical to the performance and stability of the air conditioning system, as it affects the energy efficiency and life of the system. Further, depending on the operation mode determined in step S1 and the temperature of the electronic control device 4, the system will decide how to adjust the operation state of the water heat exchange system.
Specifically, if the temperature of the electronic control device 4 is low, the second expansion valve 61 is closed, and at this time, the electronic control device 4 does not need to be cooled; if the temperature of the electronic control device 4 is high, the second expansion valve 61 is opened, and the cooling water cools the electronic control device 4. Furthermore, it is possible to provide a device for the treatment of a disease. When the temperature of the electric control device 4 is too high, the system may increase the total flow of the water heat exchange system or increase the opening of the second expansion valve 61, so that heat is taken away by more cooling water to reduce the temperature of the electric control device 4.
In addition, the change of the operation mode of the air conditioning system may affect the opening control of other expansion valves (such as the opening control of the third expansion valve 71, the fourth expansion valve 82 and the fifth expansion valve 91) in the water heat exchange system, which is described in detail above, and thus will not be described again.
According to some embodiments of the present invention, the step of controlling and adjusting the operation state of the water heat exchange system according to the current operation mode and the temperature of the electric control device 4 specifically includes:
In the case where the current operation mode is the cooling mode, the opening degree of the second expansion valve 61 is controlled and adjusted according to the temperature of the electronic control device 4.
In this embodiment, the system compares the actual temperature of the electronic control device 4 with a predetermined safe or optimal operating temperature range. If the temperature of the electronic control device 4 exceeds this range, the second expansion valve 61 needs to be opened for cooling.
In order to reduce the temperature of the electronic control device 4, the system controls the opening of the second expansion valve 61. The second expansion valve 61 is responsible for regulating the flow of cooling water through the electronic control unit 4. If the electronic control device 4 is overheated, the system increases the opening of the second expansion valve 61, so that more cooling water flows through the electronic control device 4, thereby taking more heat away.
Thus, by adjusting the opening degree of the second expansion valve 61, the system can precisely control the temperature of the electric control device 4, ensure its operation in an optimal state, and prevent the electric control device 4 from being degraded or failed due to overheating, thereby improving the stability and reliability of the entire air conditioning system.
Further, in the case that the current operation mode is the cooling mode, the step of controlling and adjusting the opening of the second expansion valve 61 according to the temperature of the electronic control device 4 specifically includes:
Under the condition that the current working mode is a refrigeration mode;
Determining that the temperature of the electric control device 4 is less than the first set temperature, and controlling the second expansion valve 61 to keep a closed state;
Or the temperature of the electric control device 4 is determined to be larger than the first set temperature, and the second expansion valve 61 is controlled to be opened at an initial valve opening degree, wherein the initial valve opening degree is determined according to the temperature of the electric control device 4.
In this embodiment, after obtaining the real-time temperature of the electronic control device 4, the system compares the real-time temperature of the electronic control device 4 with a preset first set temperature. The first set temperature is the optimal operating temperature threshold of the electronic control device 4 in the cooling mode.
If the temperature of the electronic control means 4 is less than the first set temperature, it is indicated that the temperature of the electronic control means 4 is already sufficiently low that no additional cooling is required. In this case, the system controls the second expansion valve 61 to maintain the closed state to avoid unnecessary power consumption.
If the temperature of the electronic control device 4 is greater than the first set temperature, it is indicated that the electronic control device 4 requires additional cooling. The system will open the second expansion valve 61 at the initial valve opening. This initial valve opening is determined based on the actual temperature of the electronic control device 4 to ensure that the temperature of the electronic control device 4 can quickly drop below the first set temperature.
The system then continuously monitors the temperature of the electronic control unit 4 and adjusts the opening of the second expansion valve 61 as necessary to maintain the electronic control unit 4 within the optimal operating temperature range.
Thus, by opening the second expansion valve 61 only when the temperature of the electronic control device 4 exceeds a set threshold, the system can reduce unnecessary energy consumption and improve energy efficiency. And when the temperature of the electric control device 4 increases, the system can quickly respond to and adjust the opening of the second expansion valve 61 to prevent overheating, reduce the risk of damage to equipment caused by overheating, and prolong the service life of the equipment.
Further, after the step of controlling the second expansion valve 61 to open at the initial valve opening after determining that the temperature of the electronic control device 4 is greater than the first set temperature, it further includes:
acquiring the temperature change trend of the electric control device 4 within a first set time period after the second expansion valve 61 is opened;
Determining that the temperature variation trend is a decreasing trend, controlling the opening degree of the second expansion valve 61 to decrease on the basis of the initial valve opening degree;
Or the temperature change trend is determined to be an upward trend, the opening degree of the second expansion valve 61 is controlled to be increased on the basis of the initial valve opening degree.
In the present embodiment, when the temperature of the electronic control device 4 exceeds the first set temperature, the second expansion valve 61 is opened at the initial valve opening degree to start the cooling process. After the second expansion valve 61 is opened, the system will continuously monitor the temperature change of the electronic control device 4 for a first set period of time in order to give the system sufficient time to observe the temperature change and make a corresponding adjustment.
If the monitored trend of temperature change is decreasing, indicating a good cooling effect, the temperature of the electronic control device 4 is decreasing. In this case, the system controls the opening degree of the second expansion valve 61 to be reduced so as to avoid overcooling while maintaining the temperature of the electronic control unit 4 within a suitable range.
If the monitored trend of temperature change is rising, it is indicated that the current cooling effect is insufficient to control the temperature of the electronic control device 4. In this case, the system controls the opening of the second expansion valve 61 to be increased to increase the flow rate of the cooling water, more effectively reducing the temperature of the electronic control unit 4.
Then, the system continuously monitors the temperature and the temperature change trend of the electric control device 4, and continuously adjusts the opening of the second expansion valve 61 as required until the temperature of the electric control device 4 is stabilized below the first set temperature.
In this way, the control strategy described above allows the system to dynamically adjust the opening of the second expansion valve 61 according to real-time temperature changes, ensuring a more accurate temperature control of the electronic control device 4.
Further, after the step of controlling the second expansion valve 61 to be opened at the initial valve opening degree after determining that the temperature of the electronic control device 4 is greater than the first set temperature, the method further includes:
After the second expansion valve 61 is continuously opened for a second set period of time, the temperature of the electric control device 4 is acquired again;
if the temperature of the electric control device 4 is determined to be smaller than the second set temperature, the second expansion valve 61 is controlled to be closed;
or the temperature of the electronic control device 4 is determined to be greater than the second set temperature, the second expansion valve 61 is controlled to be continuously opened, and the above steps are performed again.
In the present embodiment, when the temperature of the electronic control device 4 exceeds the first set temperature, the second expansion valve 61 is opened at the initial valve opening degree, and the cooling process is started. After the second expansion valve 61 is opened at the initial valve opening, the system is continuously opened for a second set period of time. During this time, the system will again acquire the temperature of the electronic control device 4.
If the temperature of the electronic control device 4 falls below the second set temperature after the second set time period, which indicates that the cooling effect is sufficient, the temperature of the electronic control device 4 is effectively controlled. At this point, the system will control the second expansion valve 61 to close to save energy and prevent overcooling.
If the temperature of the electronic control device 4 is still higher than the second set temperature, it is indicated that the current cooling effect is insufficient to reduce the temperature to the target range. In this case, the system will control the second expansion valve 61 to continue to open and may need to re-perform the above steps to further reduce the temperature of the electronic control unit 4.
The system then continues to monitor the temperature of the electronic control device 4 and to cycle through the above steps as needed until the temperature of the electronic control device 4 stabilizes below the second set temperature.
Thus, by setting two temperature thresholds (a first set temperature and a second set temperature) and a duration of continuous opening, the system is able to form a closed loop feedback mechanism, ensuring that the temperature of the electronic control unit 4 is accurately controlled. And, when the temperature of the electric control device 4 falls to the target range, the system closes the second expansion valve 61, reducing the energy consumption.
According to some embodiments of the present invention, the step of controlling and adjusting the operation state of the water heat exchange system according to the current operation mode and the temperature of the electric control device 4 specifically includes:
in the case where the current operation mode is the heating mode and the temperature of the electronic control device 4 is greater than the preset temperature, the second expansion valve 61, the fourth expansion valve 82, and the fifth expansion valve 91 are controlled to be opened.
