An auxiliary electric heater can be provided inside.
优选的实施方式包括：Preferred implementations include:
生活废热水源非承压式热泵热水装置还包括节流装置8，节流装置8连接在干燥过滤器3与蒸发器6之间，节流装置8为热力膨胀阀或电子膨胀阀。The non-pressurized heat pump water heater with domestic waste water source also includes a throttling device 8, which is connected between the dry filter 3 and the evaporator 6, and the throttling device 8 is a thermal expansion valve or an electronic expansion valve.
用热水设施为淋浴器9，非承压式保温蓄热水箱30与淋浴器9之间设有增压泵10。The hot water facility is a shower 9, and a booster pump 10 is arranged between the non-pressurized heat preservation hot water tank 30 and the shower 9.
废水池5内还设有废水排放阀12、溢流管13。A waste water discharge valve 12 and an overflow pipe 13 are also provided in the waste water tank 5 .
蒸发器6采用蛇形或螺旋形的钛管换热器，蒸发器6设在距废水池5底部50mm 高的底座上。The evaporator 6 adopts a serpentine or spiral titanium tube heat exchanger, and the evaporator 6 is arranged on a base 50 mm high from the bottom of the waste water pool 5 .
生活废热水源非承压式热泵热水装置是通过废水池5收集生活废热水后，废水池5中蒸发器内的热泵工质吸收洗浴废热水的热量，再通过压缩机1运行推动工质流动将热量转移到冷凝器2中，传递给与热泵工质进行热量交换的热水循环管路中的较低温水，经过循环水泵逐渐把蓄热水箱中的自来水循环升温。当用户需要使用热水时，打开热水出水管的混水阀，非承压式蓄热水箱30中的热水在重力作用下或由自动增压泵10增压后沿着出水管路流至用水点。热水跟冷水自来水在混水阀交汇，用户可以根据自身的舒适性要求，调节到适合的水温和水量。非承压式蓄热水箱30里面安装了辅助电加热器，在蓄热水箱中热水温度不足且废热水池中没有废热水可以供热量回收时可以自动或者手动开启辅助电加热器进行热量补给。The non-pressurized heat pump water heating device for domestic waste water source collects domestic waste water through the waste water pool 5, and the heat pump working medium in the evaporator in the waste water pool 5 absorbs the heat of the waste water for bathing, and then runs through the compressor 1 to drive the working water. The mass flow transfers the heat to the condenser 2, and transfers it to the lower temperature water in the hot water circulation pipeline that exchanges heat with the heat pump working fluid, and gradually heats up the tap water in the heat storage tank through the circulating water pump. When the user needs to use hot water, open the mixing valve of the hot water outlet pipe, and the hot water in the non-pressurized hot water storage tank 30 will flow along the water outlet pipe under the action of gravity or boosted by the automatic booster pump 10 flow to the water point. Hot water and cold tap water meet at the mixing valve, and users can adjust the water temperature and volume according to their own comfort requirements. An auxiliary electric heater is installed in the non-pressurized heat storage tank 30, and the auxiliary electric heater can be turned on automatically or manually when the temperature of the hot water in the heat storage tank is insufficient and there is no waste hot water in the waste water pool for heat recovery Carry out caloric supplementation.
采用生活废热水源非承压式热泵热水装置制备生活热水，有连续加热模式和间隔加热模式两种运行模式; 生活废热水源非承压式热泵热水装置间隔加热模式流程示意图如图2所示， 采用间隔加热模式时制备热水和使用热水间隔进行，此时热泵热水装置最节能高效，热水温度稳定，前两人洗浴时，直接使用隔天热泵热水装置利用蒸发器吸收的废水池中废水热量进行加热并运输至保温蓄热水箱的热水，如热水有温降则使用电加热器把热水加热到50—55℃，同时，沐浴后废水收集在沐浴器下方废水池中，第二人洗浴完毕后，如果蓄热水箱里的热水不满足下一个人的使用，对蓄热水箱进行补水，即重新注水至80L并启动热泵热水装置把蓄热水箱中的水重新加热至50—55℃;为保证废水池不过载，蓄热水箱内水加热结束后打开废水池排水阀，排掉部分废水，可开始下一轮用热水和收集废水，从而实现间隔地产生及供应热水;在用户需要一个紧接一个不间断地洗浴的特殊情况下，可以启用连续加热模式，如图3所示，在第一人使用热水结束后开始补充冷水到蓄热水箱并启动热泵热水装置加热，实现连续地产生热水，满足用户连续不间断使用热水的需求。The non-pressurized heat pump water heating device with domestic waste water source is used to prepare domestic hot water, and there are two operating modes: continuous heating mode and interval heating mode; It shows that when using the interval heating mode, the preparation of hot water and the use of hot water are carried out at intervals. At this time, the heat pump water heating device is the most energy-saving and efficient, and the temperature of the hot water is stable. The heat of the waste water in the waste water tank is heated and transported to the hot water in the thermal storage tank. If the temperature of the hot water drops, use an electric heater to heat the hot water to 50-55°C. At the same time, the waste water is collected in the shower after bathing. In the waste water pool below, after the second person finishes bathing, if the hot water in the hot water storage tank is not enough for the next person, replenish the water in the hot water storage tank, that is, refill the water to 80L and start the heat pump hot water device to turn on the stored water. The water in the hot water tank is reheated to 50-55°C; in order to ensure that the waste water tank is not overloaded, after the water in the heat storage tank is heated, the waste water tank drain valve is opened to drain part of the waste water, and the next round of hot water and water can be used. Waste water is collected to generate and supply hot water at intervals; in special cases where users need to bathe one after another without interruption, the continuous heating mode can be enabled, as shown in Figure 3, after the first person uses hot water Start to add cold water to the hot water storage tank and start the heat pump hot water device to heat, realize continuous hot water generation, and meet the needs of users for continuous and uninterrupted use of hot water.
生活废热水源非承压式热泵热水装置的间隔加热模式，前两人洗浴完毕后重新将蓄热水箱补满水并启动热泵热水装置加热至50—55℃，即使用热水时不补充水，不加热，补水和加热时不使用热水。The interval heating mode of the non-pressurized heat pump water heating device of the domestic waste water source. After the first two people take a bath, refill the water storage tank and start the heat pump water heating device to heat to 50-55 ℃, even when using hot water. Replenish water without heating, and do not use hot water for rehydration and heating.
生活废热水源非承压式热泵热水装置的连续加热模式，在用户需要一个紧接一个不间断地洗浴的特殊情况下，在第一人洗澡快结束、废水池废热水量达到最低限时即可开启热泵热水装置制热，将蓄热水箱中热水加热至55℃时开始补充冷水并继续加热，使用热水和补水及加热水同步进行。The continuous heating mode of the non-pressurized heat pump water heater with domestic waste water source can be turned on when the first person is about to finish bathing and the amount of waste water in the waste water pool reaches the minimum limit when the user needs to bathe one after another without interruption. The heat pump hot water device heats up. When the hot water in the hot water storage tank is heated to 55°C, it starts to replenish cold water and continues heating. The use of hot water, water replenishment and heating water are carried out simultaneously.
生活废热水源非承压式热泵热水装置采用非承压式的蓄水箱，与大气连通，用户使用热水时，装置不会自动补充冷水，水温保持不变，用户使用时的舒适性高。The non-pressurized heat pump hot water device of the domestic waste water source adopts a non-pressurized water storage tank, which is connected to the atmosphere. When the user uses hot water, the device will not automatically replenish cold water, and the water temperature will remain unchanged. The comfort of the user is high. .
非承压蓄热水箱的蓄水量必须大于一个人的洗浴用水量，结合本装置施工安装及使用需求特点，蓄热水箱不宜过大，因此采用满足两名用户洗浴需求用水量为原则进行设计。The water storage capacity of the non-pressurized heat storage tank must be greater than the bathing water consumption of one person. Combined with the construction, installation and use requirements of this device, the heat storage tank should not be too large, so the principle is to meet the water demand of two users for bathing design.
运行模式假设每人每日洗浴20—30分钟，50—55℃热水用量为40L，为了避免第一个人洗浴完毕，第二人可能存在热水储量不够的因素，因此水箱的设计容积应该在满足两人设计用水量的基础上适当扩大，以消除不稳定因素的影响。最终设蓄热水箱的体积为80—90L。The operation mode assumes that each person takes a bath for 20-30 minutes a day, and the consumption of hot water at 50-55°C is 40L. In order to prevent the first person from bathing, the second person may have insufficient hot water storage. Therefore, the design volume of the water tank should be Appropriately expand on the basis of meeting the design water consumption of two people to eliminate the influence of unstable factors. Finally, the volume of the hot water tank is set to be 80-90L.
生活废热水源非承压式热泵热水装置的蒸发器采用了自行设计平放高度较小的蒸发器，在较少废水的情况下便能被浸没，启动热泵。The evaporator of the non-pressurized heat pump water heating device for domestic waste water sources adopts a self-designed evaporator with a small horizontal height, which can be submerged with less waste water and start the heat pump.
在所有人洗漱完毕后，蓄热水箱重新把水补满至80L。热泵机组利用废热水再把水加热到50℃以上，以供次日或下次漱口洗脸和洗澡使用。之后排空废水，以免污水集聚，滋生蚊虫。After everyone washes up, the water storage tank is refilled to 80L. The heat pump unit uses the waste hot water to heat the water to above 50°C for the next day or next time to wash the mouth, wash the face and take a bath. Then drain the waste water to prevent the accumulation of sewage and the breeding of mosquitoes.
以上所述是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明所述原理的前提下，还可以作出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。The above description is a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, and these improvements and modifications can also be made. It should be regarded as the protection scope of the present invention.
