Although the indoor temperature will drop, the heat emitted by the condenser can easily cause a heat island effect, which is not conducive to energy saving and emission reduction. In addition, hot water accounts for a large part of household water, and traditional technologies use gas or electricity to heat hot water, which is not conducive to energy conservation. If the heat dissipation from the air-conditioning condenser is recovered and applied to the heating of domestic water, the heat island effect can be effectively reduced, and the effect of energy saving and emission reduction can be achieved.

Mode, the domestic hot water system provided by this application is also based on this air conditioner.
具体地，家庭热水系统包括：热水器，热水器包括水箱以及设于水箱的电加热装置，电加热装置用于对水箱内的水进行加热；以及，Specifically, the domestic hot water system includes: a water heater, the water heater includes a water tank and an electric heating device arranged in the water tank, and the electric heating device is used to heat the water in the water tank; and,
单模式空调，仅具有制冷模式，单模式空调包括依次串联的蒸发器、压缩机以及冷凝器.其中，冷凝器包括并联的水冷式冷凝器以及空冷式冷凝器，水冷式冷凝器设于水箱内，空冷式冷凝器用于设于室外。需要说明的是，在本申请提供的技术方案中，空调由于只具有制冷模式，因此冷凝器只存在散热情况。水冷式冷凝器置于水箱内，利用水箱内的水进行换热，空冷式冷凝器置于室外，如传统技术中的冷凝器一样，利用空气进行换热。在本申请提供的技术方案中，通过设置不同的水冷式冷凝器以及空冷式冷凝器，在空调制冷时，空调采用水冷式冷凝器散热，水箱可以吸收水冷式冷凝器的散热，达到对家庭用水加热的效果；在热水达到设定温度后，空调采用空冷式冷凝器散热，切断对水箱的加热的情况下保证空调的正常运行，该家庭热水系统有效利用了空调的散热，达到了节能减排的效果。Single-mode air conditioners only have refrigeration mode. Single-mode air conditioners include evaporators, compressors, and condensers connected in series. Among them, the condensers include parallel water-cooled condensers and air-cooled condensers, and the water-cooled condensers are installed in the water tank. , The air-cooled condenser is used to be located outdoors. It should be noted that, in the technical solution provided by the present application, since the air conditioner only has a cooling mode, the condenser only has heat dissipation. The water-cooled condenser is placed in the water tank, and the water in the water tank is used for heat exchange, and the air-cooled condenser is placed outside, like the condenser in the traditional technology, which uses air for heat exchange. In the technical solution provided by this application, by setting different water-cooled condensers and air-cooled condensers, when the air conditioner is cooling, the air conditioner uses the water-cooled condenser to dissipate heat, and the water tank can absorb the heat dissipation of the water-cooled condenser, so as to achieve the purpose of saving water for households. The effect of heating; after the hot water reaches the set temperature, the air conditioner uses an air-cooled condenser to dissipate heat, and the normal operation of the air conditioner is guaranteed when the heating of the water tank is cut off. The domestic hot water system effectively uses the heat dissipation of the air conditioner to achieve energy saving The effect of emission reduction.
进一步地，由于存在线路的切换，在需要加热热水时，压缩机需要与水冷式冷凝器连通，在不需要加热热水时，压缩机与空冷式冷凝器连通，因此在本申请提供的技术方案中，压缩机与水冷式冷凝器以及空冷式冷凝器通过电子三通阀连通。电子三通阀具有三个接点，一个连通压缩机，一个连通水冷式冷凝器，一个连通空冷式冷凝器；形成两条回路，一个是压缩机连通水冷式冷凝器，一个是压缩机连通空冷式冷凝器。Further, due to the switching of circuits, when hot water needs to be heated, the compressor needs to communicate with the water-cooled condenser, and when hot water does not need to be heated, the compressor communicates with the air-cooled condenser. In the scheme, the compressor communicates with the water-cooled condenser and the air-cooled condenser through an electronic three-way valve. The electronic three-way valve has three contacts, one is connected to the compressor, one is connected to the water-cooled condenser, and the other is connected to the air-cooled condenser; two circuits are formed, one is the compressor connected to the water-cooled condenser, and the other is connected to the compressor to the air-cooled condenser. condenser.
更进一步地，由于家庭热水温度不宜超过75℃，在本申请提供的技术 方案中，还需要对系统的温度进行监控。因此，家庭热水系统还包括温度检测装置，温度检测装置包括第一温度检测结构和第二温度检测结构，第一温度检测结构设于水箱内，用于检测水箱内水的温度，所述第二温度检测结构设于压缩机上，用于检测压缩机的顶盖排气温度。需要说明的是，压缩机的顶盖排气温度接近于冷凝器的温度，一般情况下，为了保证较好的换热效率，冷凝器与热水的温度差应该保持在10℃以上。通过检测压缩机的顶盖排气温度以及水箱温度，一方面保证水箱温度在用户预设的温度范围内，另一方面通过监控两个温度之间的温度差，在两者温度差较小时能够及时通过调节压缩机功率增大两者的温度差，达到良好的换热效果。Furthermore, since the temperature of domestic hot water should not exceed 75°C, in the technical solution provided by this application, it is also necessary to monitor the temperature of the system. Therefore, the domestic hot water system also includes a temperature detection device. The temperature detection device includes a first temperature detection structure and a second temperature detection structure. The first temperature detection structure is arranged in the water tank for detecting the temperature of the water in the water tank. The second temperature detecting structure is arranged on the compressor, and is used for detecting the discharge temperature of the top cover of the compressor. It should be noted that the discharge temperature of the top cover of the compressor is close to the temperature of the condenser. In general, in order to ensure better heat exchange efficiency, the temperature difference between the condenser and the hot water should be kept above 10°C. By detecting the discharge temperature of the top cover of the compressor and the temperature of the water tank, on the one hand, ensure that the temperature of the water tank is within the temperature range preset by the user; on the other hand, by monitoring the temperature difference between the two temperatures, it can Increase the temperature difference between the two by adjusting the power of the compressor in time to achieve a good heat exchange effect.
由于本申请提供的技术方案中，冷媒流动包括两个回路，为了防止冷媒在两个冷凝器之间串流，水冷式冷凝器以及空冷式冷凝器均包括冷媒入口以及冷媒出口，各冷媒出口处均设有止回阀。进一步地，由于水冷式冷凝器设于水箱内，冷凝器直接与水箱接触，为了防止冷凝器长时间浸泡于水中被腐蚀，冷凝器的换热管以及散热片上均涂布有特氟龙防腐蚀层。In the technical solution provided by this application, the refrigerant flow includes two loops. In order to prevent the refrigerant from flowing between the two condensers, the water-cooled condenser and the air-cooled condenser both include a refrigerant inlet and a refrigerant outlet. All have check valves. Furthermore, since the water-cooled condenser is installed in the water tank, the condenser is in direct contact with the water tank. In order to prevent the condenser from being corroded after being soaked in water for a long time, the heat exchange tubes and cooling fins of the condenser are coated with Teflon anti-corrosion Floor.
基于上述家庭热水系统，本申请还提供了一种家庭热水系统控制方法，包括：Based on the above domestic hot water system, the present application also provides a method for controlling the domestic hot water system, including:
S10、获取空调工作状态；S10. Obtain the working status of the air conditioner;
S20、若空调处于工作状态，连通蒸发器、压缩机以及水冷式冷凝器；S20. If the air conditioner is in working condition, connect the evaporator, the compressor and the water-cooled condenser;
S30、获取用户设定水箱温度；S30. Obtaining the temperature of the water tank set by the user;
S40、每间隔预设时间，获取一次实际水箱温度；S40. Acquiring the actual temperature of the water tank every preset time interval;
S50、若所述实际水箱温度超过所述设定水箱温度，连通所述蒸发器、所述压缩机以及所述空冷器冷凝器；S50. If the actual water tank temperature exceeds the set water tank temperature, connect the evaporator, the compressor, and the air cooler condenser;
S60、若空调处于关闭状态，打开热水器的电加热装置。S60. If the air conditioner is turned off, turn on the electric heating device of the water heater.
如前所述，本申请提供的空调为单模式空调，只进行制冷模式。由于日常生活中，家中需要常备热水，因此在空调工作的时候，水箱中的水吸收冷凝器散发的温度进行加热，空调在不工作的时候，水箱中的水依靠热水器自身的加热装置进行加热。具体地，若空调处于工作状态，此时依靠水冷式冷凝器进行散热，冷媒经过蒸发器、压缩机以及水冷式冷凝器组成的回路。在空调工作的过程中，水温会持续升高，一般情况下，水温会升高到用户设定温度便不再继续升高。因此在本申请提供的技术方案中，会 获取用户设定的水箱温度，若实际水箱温度超过设定水箱温度，则需要关闭发热源，即切换冷媒循环回路，使用空冷式冷凝器对空调进行散热。当空调未开启时，则使用热水器自带的电加热装置对水箱中的水进行加热。As mentioned above, the air conditioner provided by this application is a single-mode air conditioner, which only performs cooling mode. In daily life, hot water needs to be kept at home. Therefore, when the air conditioner is working, the water in the water tank absorbs the temperature emitted by the condenser for heating. When the air conditioner is not working, the water in the water tank is heated by the heating device of the water heater itself. . Specifically, if the air conditioner is in a working state, it relies on a water-cooled condenser to dissipate heat, and the refrigerant passes through a circuit composed of an evaporator, a compressor, and a water-cooled condenser. During the working process of the air conditioner, the water temperature will continue to rise. Generally, the water temperature will rise to the temperature set by the user and will not continue to rise. Therefore, in the technical solution provided by this application, the water tank temperature set by the user will be obtained. If the actual water tank temperature exceeds the set water tank temperature, the heat source needs to be turned off, that is, the refrigerant circulation circuit should be switched, and an air-cooled condenser should be used to dissipate heat from the air conditioner. . When the air conditioner is not turned on, the electric heating device provided by the water heater is used to heat the water in the water tank.
由于空调并不是处于常开状态，在室内温度下降到一定程度时，用户会选择关闭空调。在本申请提供的技术方案中，在S50、“若所述实际水箱温度超过所述设定水箱温度，连通所述蒸发器、所述压缩机以及所述空冷器冷凝器”之前还包括：Since the air conditioner is not always on, when the indoor temperature drops to a certain level, the user will choose to turn off the air conditioner. In the technical solution provided by this application, before S50, "if the actual water tank temperature exceeds the set water tank temperature, connect the evaporator, the compressor, and the air cooler condenser", it also includes:
S41、每间隔预设时间获取一次空调的工作状态；S41. Acquiring the working state of the air conditioner every preset time interval;
S42、若空调处于关闭状态、且所述实际水箱温度小于所述设定水箱温度，打开热水器的电加热装置。S42. If the air conditioner is off and the actual water tank temperature is lower than the set water tank temperature, turn on the electric heating device of the water heater.
需要说明的是，热水器中的热水需要保证在一定的温度区间内，若热水器中的热水没有达到需要的温度，而此时空调又处于关闭状态，则需要打开热水器的电加热装置对水加热，防止热水温度不够的情况发生。It should be noted that the hot water in the water heater needs to be within a certain temperature range. If the hot water in the water heater does not reach the required temperature and the air conditioner is turned off at this time, it is necessary to turn on the electric heating device of the water heater to control the temperature of the water. Heating to prevent the occurrence of insufficient hot water temperature.
进一步地，在S42、“打开热水器的电加热装置”之后还包括：Further, after S42, "turn on the electric heating device of the water heater", it also includes:
S43、每间隔预设时间，获取一次实际水箱温度；S43. Acquiring the actual temperature of the water tank every preset time interval;
S44、若所述实际水箱温度超过所述设定水箱温度，关闭所述电加热装置。S44. If the actual water tank temperature exceeds the set water tank temperature, turn off the electric heating device.
如前所述，热水器中的热水温度不适宜超过75℃，一般情况会以用户设定的温度为准，若用户未设定温度，则以75℃为加热温度。与利用水冷式冷凝器加热水的步骤相似，在热水温度超过设定温度后，需要关闭电加热装置，防止水温超过热水器温度上限。As mentioned above, the temperature of hot water in the water heater should not exceed 75°C. Generally, the temperature set by the user will prevail. If the user does not set the temperature, the heating temperature will be 75°C. Similar to the steps of using a water-cooled condenser to heat water, after the hot water temperature exceeds the set temperature, the electric heating device needs to be turned off to prevent the water temperature from exceeding the upper limit of the water heater temperature.
根据本申请提供的一种家庭热水系统控制方法，在S40、“每间隔预设时间，获取一次实际水箱温度”之后还包括：According to a method for controlling a domestic hot water system provided by the present application, after S40, "obtaining the actual temperature of the water tank at intervals of a preset time" further includes:
S45、每间隔预设时间，获取一次压缩机出气口温度；S45. Acquiring the air outlet temperature of the compressor at every preset time interval;
S46、计算所述实际水箱温度与所述压缩机出气口温度的第一温度差值；S46. Calculate a first temperature difference between the actual water tank temperature and the air outlet temperature of the compressor;
S47、获取空调实际温度以及设定温度；S47. Obtain the actual temperature and the set temperature of the air conditioner;
S48、计算所述空调实际温度以及所述设定温度的第二温度差值；S48. Calculate a second temperature difference between the actual temperature of the air conditioner and the set temperature;
S49、根据所述第一温度差值和所述第二温度差值调节压缩机的功率。S49. Adjust the power of the compressor according to the first temperature difference and the second temperature difference.
如前所述，压缩机顶盖排气温度与冷凝器温度近似，而水冷式冷凝器 与水箱中水的温度差又决定了两者之间的换热效率，一般情况下在10℃以上为最佳。而受到环境因素的影响以及用户设定空调参数的影响，两者之间的温度差有时会偏小，此时并不利于水温的提升。若要提高两者之间的温差，可通过提高压缩机的功率进行，一般情况下，提升压缩机的功率，可提高冷凝器的散热温度。但是提高压缩机的功率，也需要考虑到室内气温以及空调设定温度的对比，若室温已经达到了空调设定温度，此时再提高压缩机功率，势必会造成温度的继续下降，引起用户的不适。因此，在本申请提供的技术方案中，每间隔预设时间，获取一次压缩机出气口温度，计算实际水箱温度与压缩机出气口温度的第一温度差值，再获取空调实际温度以及设定温度，计算空调实际温度以及设定温度的第二温度差值；根据第一温度差值和第二温度差值调节压缩机的功率。如此设置，既满足了换热效率的要求，又不影响到用户的空调使用体验。As mentioned above, the exhaust temperature of the top cover of the compressor is similar to the temperature of the condenser, and the temperature difference between the water-cooled condenser and the water in the water tank determines the heat exchange efficiency between the two. Generally, it is above 10°C. optimal. Affected by environmental factors and the air-conditioning parameters set by the user, the temperature difference between the two may sometimes be too small, which is not conducive to the improvement of the water temperature. If you want to increase the temperature difference between the two, you can increase the power of the compressor. Generally, increasing the power of the compressor can increase the cooling temperature of the condenser. However, to increase the power of the compressor, it is also necessary to consider the comparison between the indoor air temperature and the set temperature of the air conditioner. If the room temperature has reached the set temperature of the air conditioner, increasing the power of the compressor at this time will inevitably cause the temperature to continue to drop, causing user frustration. discomfort. Therefore, in the technical solution provided by this application, the air outlet temperature of the compressor is acquired once every preset time interval, the first temperature difference between the actual water tank temperature and the air outlet temperature of the compressor is calculated, and then the actual temperature of the air conditioner and the set temperature are obtained. Temperature, calculate the second temperature difference between the actual temperature of the air conditioner and the set temperature; adjust the power of the compressor according to the first temperature difference and the second temperature difference. Such setting not only satisfies the requirement of heat exchange efficiency, but also does not affect the user's experience of using the air conditioner.
更进一步地，S49、“根据所述第一温度差值和所述第二温度差值调节压缩机的功率”包括：Furthermore, S49, "Adjusting the power of the compressor according to the first temperature difference and the second temperature difference" includes:
S491、若所述第一温度差值小于第一预设值，第二温度差值大于第二预设值，增大所述压缩机的功率。S491. If the first temperature difference is smaller than the first preset value and the second temperature difference is larger than the second preset value, increase the power of the compressor.
可以理解的是，第一预设值可以设为10，当第一温度差值小于10时，即换热效率较低，需要考虑调整压缩机功率。此时若第二效率大于第一预设值，第一预设值可以设为3-5，此时实际温度与空调设定温度差距还较大，可以在不影响用户使用体验的前提下提高压缩机的功率。It can be understood that the first preset value may be set to 10, and when the first temperature difference is less than 10, that is, the heat exchange efficiency is low, and it is necessary to consider adjusting the power of the compressor. At this time, if the second efficiency is greater than the first preset value, the first preset value can be set to 3-5. At this time, the gap between the actual temperature and the set temperature of the air conditioner is still large, and it can be increased without affecting the user experience. The power of the compressor.
