With reference to fig. 1, an embodiment of the present disclosure provides a method for adjusting a heat exchange system, where the heat exchange system includes a heat collecting pipeline, a heat storage box, and a heat releasing pipeline, the heat collecting pipeline includes a plurality of branch pipes and valves disposed on the branch pipes, the branch pipes can absorb heat of a plurality of heat releasing devices, and the method for adjusting the heat exchange system includes:
s10, taking the heat release device with the actual temperature higher than the preset temperature as a target heat release device;
s20, in the case that the number of the target heat releasing devices is multiple, determining the target heat releasing device capable of absorbing heat as a first heat releasing device according to the temperature difference condition among the target heat releasing devices and the distance between the target heat releasing devices and the heat storage box body;
and S30, opening a valve on the branch pipe corresponding to the first heat releasing device so as to transfer the heat of the first heat releasing device to the heat storage tank body.
The heat storage box body stores heat exchange media, and the heat collecting pipeline and the heat releasing pipeline are internally circulated with the heat exchange media. The heat collecting pipeline is arranged close to the heat-collecting device, and absorbs heat released by the heat-collecting device when a heat exchange medium flows to the heat collecting pipeline; when the heat exchange medium flows into the heat storage box body, heat is stored in the heat storage box body; when the heat exchange medium flows to the heat release pipeline, the heat is released. The heat release pipeline is arranged close to the device needing heat supply. Alternatively, the cold is water. The heat exchange is carried out through water flow, and the heat of the heat releasing device is absorbed, stored and utilized.
The heat release device is a device capable of releasing heat in the working process, and the part of heat is usually naturally released in the external environment and is relatively wasted. There are a variety of heat emitting devices in the home environment, such as range hoods, gas ranges, built-in ovens, computer cabinets, and the like. When a user cooks in a kitchen, the temperatures of the range hood and the gas stove are increased, and the part of heat can be utilized. The built-in oven is an oven embedded in a wall, the temperature is high after the barbecue is finished, and the heat of the built-in oven can be utilized. When the computer runs, a CPU of the computer is easy to generate heat, so that the temperature of the case is high, and the partial heat can be utilized. In practical application, the heat collecting pipe can be extended to the vicinity of the heating device to absorb heat generated by the heating device. In addition, the drain line of the domestic sink will also release some heat. Because some water taps are provided with heating devices, hot water can be generated, heat is reserved on the water discharge pipeline, and the heat collecting pipeline can be extended to the position near the water discharge pipeline to absorb heat.
When the number of the heat release devices is multiple, the heat collecting pipeline is divided into a plurality of branch pipes, so that each heat release device can collect heat through the corresponding branch pipe. The branch pipe is provided with a valve, and the heat of the heat releasing device corresponding to the branch pipe can be adjusted whether to be collected or not by adjusting the opening and closing of the valve. The heat exchange medium flows to the heat storage tank body, and can store heat in the heat storage tank body. Optionally, the housing of the thermal storage tank is provided with an insulating layer. Thus, the heat can be prevented from being dissipated through the shell of the heat storage box body. Optionally, the housing of the thermal storage tank is provided with a thermal storage material. The heat storage material can store heat for a long time.
A temperature sensor can be arranged on the heat releasing device or near the heat releasing device to detect the actual temperature of the heat releasing device and grasp the temperature condition of the heat releasing device in time. When the exothermic device is exothermic, it is not necessary to collect any degree of heat release. Therefore, a preset temperature is set, and in the case where the actual temperature of the heat releasing device is higher than the preset temperature, it is regarded as a target heat releasing device. When the actual temperature of the heat releasing device is higher than the preset temperature, the heat released by the heat releasing device can be collected and utilized, and the heat releasing device is taken as a target heat releasing device. Optionally, the preset temperature is 15 ℃. When the exothermic device is higher than 15 ℃, the target exothermic device can be used.
There may be multiple target heat sinks among the multiple heat sinks, i.e., there are multiple heat sink temperatures to meet the heat exchange requirements. Although there are a plurality of target heat release devices, if all branch pipes are connected for heat exchange, the flow of the heat exchange medium of each branch pipe is small, and efficient heat exchange cannot be performed. In this case, therefore, those that can absorb heat are determined from the plurality of target heat releasing devices as the first heat releasing devices, based on the temperature difference situation between the plurality of target heat releasing devices and the distance between the plurality of target heat releasing devices and the heat storage tank. The first heat releasing means the heat releasing means most suitable for heat exchange among the target heat releasing means.
The temperature difference between the target heat release devices can reflect the temperature difference between the target heat release devices, and the temperatures of the target heat release devices may be close to each other or the temperatures of the target heat release devices may be much different. And selecting a proper target heat release device according to the temperature difference. In addition to the temperature differential condition, the distance between the target heat sink and the thermal storage tank is also a factor. If the distance between the target heat releasing device and the heat storage box body is long, the heat collecting pipeline is long, the transmission distance of the heat exchange medium is long, and heat dissipation loss can also exist in the transmission process. Therefore, a target heat releasing device that can absorb heat is determined as the first heat releasing device according to the temperature difference situation and the distance factor.
After the first heat release device is determined, the valve on the branch pipe corresponding to the first heat release device is opened, so that the heat exchange medium can flow to the first heat release device to absorb heat, and the heated heat exchange medium flows back to the heat storage box body to store heat in the heat storage box body.
Optionally, the heat collecting circuit and the heat releasing circuit are provided with pump means. The pump device can drive the heat exchange medium to flow, and heat loss caused by too low flow speed is reduced. Optionally, the heat exchange system further comprises a solar panel, and the solar panel is connected with the pump device. The solar cell panel provides electric energy for the pump device, and the solar cell panel is energy-saving and environment-friendly.
The heat release pipeline can be close to the device needing heat, for example, the heat release pipeline is extended to the outdoor heat exchanger of the air conditioner, the heat release pipeline can transfer heat to the outdoor heat exchanger, the outdoor heat exchanger in winter can be prevented from frosting, the evaporation temperature of the outdoor heat exchanger can be increased, the power of the air conditioning system is reduced, and the energy efficiency is improved. Therefore, the operation temperature range of the air conditioner in winter is expanded downwards.
In some embodiments, the determining the first heat releasing device which can absorb heat according to the temperature difference condition between the target heat releasing devices and the distance between the plurality of target heat releasing devices and the heat storage tank body includes: determining a temperature difference between the highest temperature and the lowest temperature target heat release devices; under the condition that the temperature difference is greater than or equal to a preset value, taking a target heat release device with the highest temperature as a first heat release device; under the condition that the temperature difference is smaller than a preset value, determining a first heat releasing device capable of absorbing heat according to the distances between the target heat releasing devices and the heat storage box body; wherein the temperature difference is taken as an absolute value.
Under the condition of not considering the distance factor, the target heat releasing device with the highest temperature releases the most heat, the heat exchange effect with the heat exchange medium is the best, and the target heat releasing device with the lowest temperature has a poor effect. And calculating the temperature difference between the target heat release devices with the highest temperature and the lowest temperature, and judging the temperature difference degree between the target heat release devices according to the temperature difference. And setting a preset value, and indicating that two target heat release devices with larger difference exist between the target heat release devices under the condition that the temperature difference is greater than or equal to the preset value. At this time, the distance factor is not considered, and the target heat releasing device with the highest temperature is directly used as the first heat releasing device for heat exchange. And under the condition that the temperature difference is smaller than the preset value, the temperatures of the target heat releasing devices are relatively close, and at the moment, the first heat releasing device capable of absorbing heat is determined according to the distances between the target heat releasing devices and the heat storage box body. Therefore, the selected first heat releasing device has a good heat exchange effect with the heat storage box body.
Optionally, the preset value is 15. When the temperature difference between the highest and lowest temperature target heat sinks is greater than or equal to 15, it indicates that the temperature difference is greater. Illustratively, the temperature of the target heat releasing device with the lowest temperature is 20 ℃, the temperature of the target heat releasing device with the highest temperature is 40 ℃, the temperature difference between the target heat releasing device with the lowest temperature and the target heat releasing device with the highest temperature is 20 ℃, at this time, the target heat releasing device with the temperature of 40 ℃ is used as a first heat releasing device, and the valve on the branch is opened for heat collection, so that the heat exchange effect is better.
In some embodiments, determining a first heat releasing device that can absorb heat based on distances between the plurality of target heat releasing devices and the heat storage tank includes: the distances between the plurality of target heat releasing devices and the heat storage tank are compared, and the target heat releasing device closest to the heat storage tank is taken as the first heat releasing device.
The target heat releasing device closest to the heat storage box body has the shortest transmission distance after the heat exchange medium collects heat, and the heat dissipated on the heat collecting pipe is relatively less. In the case where the temperature difference between the plurality of target heat releasing devices is not large, the target heat releasing device closest to the target heat releasing device may be used as the first heat releasing device to achieve the optimal heat exchange effect. How to determine the distance between the heat release devices and the heat storage box body can be measured or estimated when the heat exchange system is installed, and the distance is recorded into a controller of the heat exchange system in advance so as to be called in time. It is also possible that the length of the branch pipe from the heat storage tank to the heat releasing device is measured at the time of installation and recorded in the controller of the heat exchange system.
In some embodiments, after opening the valve on the branch pipe corresponding to the first heat-releasing device, the method further comprises: selecting one of the remaining target heat releasing devices as a second heat releasing device in a case where a temperature decrease rate of the first heat releasing device is greater than or equal to a first value; and opening a valve on the branch pipe corresponding to the second heat release device.
During the heat exchange between the branch pipe and the first heat releasing device, the first heat releasing device may have a temperature drop, which is caused by the gradual temperature drop due to the stop of the operation of the heat releasing device. For a deactivated heat-emitting device, this can be determined by calculating the rate of temperature decrease. When the rate of temperature decrease is greater than or equal to the first value, indicating that the rate of temperature decrease is too fast, it is assumed that the heat-emitting device is not operating or the temperature is about to meet the heat exchange requirements. At this time, one of the remaining heat-releasing devices is selected as the second heat-releasing device, so that the heat collecting pipeline collects the heat of the second heat-releasing device. Like this, can be when first heat release device is about to the heat not enough, in time launch the second heat release device and carry out the heat transfer to make the heat accumulation box can last the heat accumulation.
Optionally, the closing of the valve on the branch of the first heat emitting device is delayed in the event that the rate of temperature drop of the first heat emitting device is greater than or equal to a first value. The valves on the first exothermic assembly manifold are not immediately closed, but are delayed to fully collect the available heat remaining on the first exothermic assembly. Alternatively, the higher the first exothermic assembly temperature, the longer the delay time. The delay time may be made somewhat longer the higher the temperature of the first heat-releasing device, the longer the time it takes for the temperature to drop below the preset temperature. Optionally, the valve on the branch pipe of the first heat release device is closed after delaying 1 min-3 min. Optionally, the temperature decrease rate is 3 ℃/min to 10 ℃/min. When the rate of temperature decrease is within the range, it is determined that the first heat-emitting device is out of service or the temperature is about to fail to meet the heat exchange requirement.
In some embodiments, selecting one of the remaining target heat emitting devices as the second heat emitting device comprises: selecting one of the other target heat-releasing devices which is closest to the heat storage tank as a second heat-releasing device when the difference between the target temperature and the actual temperature of the heat storage tank is smaller than a second value; in the case where the difference between the target temperature and the actual temperature of the heat storage tank is greater than or equal to the second value, the one closest to the temperature of the first heat releasing device is selected as the second heat releasing device.
The target temperature of the heat storage box body is the temperature at which the heat storage box body can meet the heat release of the heat release pipeline, and if the difference between the actual temperature of the heat storage box body and the target temperature is smaller than a second value, the actual temperature of the heat storage box body is close to the target temperature. At this time, the target heat releasing device closest to the heat storage tank is selected as the second heat releasing device, so that the heat exchange medium can be rapidly circulated between the heat storage tank and the second heat release, and the temperature of the heat storage tank can reach the target temperature as soon as possible. Optionally, the target temperature of the thermal storage tank is 20 ℃ to 40 ℃. Values can be taken within this range as the target temperature of the thermal storage tank. Optionally, the second value is 5. When the difference between the actual temperature of the heat storage tank and the target temperature is less than 5, it is considered that the actual temperature of the heat storage tank approaches the target temperature.
In the case where the difference between the target temperature and the actual temperature of the heat storage tank is greater than or equal to the second value, which indicates that the difference between the actual temperature and the target temperature of the heat storage tank is large, the heat release device closest to the temperature of the first heat release device is selected as the second heat release device. The first heat releasing means temperature is a temperature before the first heat releasing means temperature starts to decrease, and when there is a target heat releasing means close to the temperature, it indicates that the target heat releasing means is the second highest temperature means among the remaining target heat releasing means. The heat exchange device is used as a second heat releasing device to exchange heat with the heat exchange medium in the branch pipe, so that more heat can be supplied to the heat storage box body, and the temperature of the heat storage box body can be raised to a target temperature.
In some embodiments, the method for conditioning a heat exchange system further comprises: and determining the flow of the heat exchange medium in the heat release pipeline according to the temperature of the heat storage box body, and adjusting the flow of the heat exchange medium in the heat release pipeline. The flow of the heat exchange medium in the heat release pipeline is adjusted, and the heat release degree of the heat release pipeline can be influenced. And determining the flow of the heat exchange medium in the heat release pipeline according to the temperature of the heat storage box body so as to ensure that the heat exchange is relatively uniform.
In some embodiments, the higher the temperature of the heat storage tank, the smaller the flow rate of the heat exchange medium in the heat release line. The higher the temperature of the heat storage box body is, the smaller the flow of the heat exchange medium in the heat release pipeline is regulated to ensure that the heat exchange medium can fully release heat in the heat release pipeline, so that a device needing heat can fully absorb the heat. The lower the temperature of the heat storage box body is, the larger the flow of the heat exchange medium in the heat release pipeline is, so that the heat exchange medium can exchange heat with a device needing heat quickly.
Optionally, the relationship between the temperature of the heat storage tank and the flow rate of the heat exchange medium in the heat release pipeline is as follows:
Q＝k*(T0-t)，
wherein Q is the flow of the heat exchange medium in the heat release pipeline, T is the actual temperature of the heat storage box body, k is a proportional parameter greater than zero, and T0For a preset temperature of the heat storage tank, and T0T > t. And when the temperature of the heat storage box body is closer to the preset temperature, the calculated flow of the heat exchange medium is smaller. Through the calculation formula, the flow of the heat exchange medium in the heat release pipeline can be calculated according to the actual temperature and the preset temperature of the heat storage box body.
Alternatively, 0.2 ≦ k ≦ 1. Taking values in the range can calculate to obtain a proper flow value. Exemplarily, k is 0.6, T020 ℃, T18 ℃, then Q ═ k (T ═ k ═ T ═ c0-t)＝0.6*(20-18)＝1.2m3/h。
Alternatively, 0.5m3/h≤Q≤3.5m3H is used as the reference value. When the flow value calculated by the above calculation formula is less than 0.5m3When the reaction time is/h, take 0.5m3H; when the calculated flow value is higher than 3.5m3When the reaction time is/h, take 3.5m3H is used as the reference value. In this way, the flow rate value can be kept within a suitable range.
Alternatively, when the temperature of the heat storage tank body is lower than the set temperature, the operation of the pump device on the heat release pipeline is stopped, so that the flow rate is zero. Alternatively, the set temperature is 15 ℃. The temperature of the heat storage box body is lower than the set temperature, which indicates that the heat storage box body is not suitable for supplying heat to the device needing heat, the pump device can be closed, the flow is enabled to return to zero, and the heat exchange is stopped.
