Detailed Description
An embodiment of the present invention provides an air conditioner condensate recycling device, and fig. 1 is a schematic structural diagram of an air conditioner condensate recycling device according to an embodiment of the present invention. Referring to fig. 1, the apparatus for recycling condensed water of an air conditioner of the present invention includes a thermal insulation water tank 10, a heat exchanger 20, a water storage tank 30, and a control device 40.
The hot water tank 10 is communicated with a condensate drain pipe of an air conditioner to temporarily store condensate water, and a condensate water temperature detecting device 11 and an ambient temperature detecting device 12 for detecting the temperature of the condensate water therein and the temperature of the external environment are provided inside and outside the hot water tank 10, respectively.
The heat exchanger 20 is selectively communicated with the heat preservation water tank 10, and a refrigerant temperature detection device 21 for detecting the temperature of the refrigerant in the heat exchanger 20 is arranged on the surface of the heat exchanger. It should be noted that "selectively" as used herein means that the heat exchanger 20 is communicated with the insulated water tank 10 only under specific conditions. The specific condition may be, for example, that the difference between the ambient temperature and the temperature of the condensed water in the holding water tank 10 is greater than a first preset temperature threshold.
The water storage tank 30 is selectively communicated with the heat exchanger 20 for storing the condensed water flowing out of the heat exchanger 20. It should be noted that "selectively" as used herein means that the water storage tank 30 is in communication with the heat exchanger 20 only under specific conditions. The specific condition may be, for example, that the difference between the ambient temperature and the temperature of the condensed water in the heat exchanger 20 is less than or equal to a second preset temperature threshold.
The control device 40 is configured to cause at least part of the condensed water in the holding water tank 10 to flow into the heat exchanger 20 as the refrigerant when the difference between the ambient temperature and the temperature of the condensed water in the holding water tank 10 is greater than a first preset temperature threshold, and control the refrigerant temperature detection device 21 and the ambient temperature detection device 12 to detect the temperature of the condensed water in the heat exchanger 20 and the ambient temperature at regular time, so as to cause the condensed water in the heat exchanger 20 to be discharged to the water storage tank 30 when the difference between the ambient temperature and the temperature of the condensed water in the heat exchanger 20 is less than or equal to a second preset temperature threshold.
Therefore, the air conditioner condensate water recycling device firstly utilizes the heat preservation water tank 10 with the heat preservation function to temporarily store the condensate water so as to avoid the loss of cold energy in the condensate water as much as possible; then when the difference between the ambient temperature and the temperature of the condensed water reaches a certain degree, at least part of the collected condensed water exchanges heat with the ambient air through the heat exchanger 20, so that the temperature of the ambient air is changed, and the cold energy of the condensed water is effectively recycled; the condensed water after recovering the cold quantity is stored in the water storage tank 30, and the temperature of the condensed water is appropriate, the PH value is neutral, and the condensed water is very suitable for flower and fish culture, so the condensed water in the water storage tank 30 can be used for watering flowers, fish culture, flushing a toilet or other purposes, and the water resource is saved. The air conditioner condensate water recycling device can be placed in a toilet, a kitchen or other indoor areas without the air conditioner, improves the living environment of users, and makes full use of condensate water to the maximum extent.
Specifically, the thermal insulation water tank 10 may be a closed water tank made of thermal insulation material. A filter 13 may be disposed on a path of the heat-insulating water tank 10 communicating with a condensed water drain pipe of the air conditioner to primarily filter condensed water flowing into the heat-insulating water tank 10 to remove impurities in the condensed water. The condensed water temperature detecting device 11 may be disposed at the bottom of the thermal insulation water tank 10 to ensure that the condensed water temperature detecting device 11 can detect the temperature of the condensed water no matter how much condensed water is collected therein. The ambient temperature detecting device 12 may be disposed on an outer wall of the heat preservation water tank 10 and exposed to an ambient space where the air conditioner condensate recycling device is located, so as to controllably detect an ambient temperature of the ambient space. Both the condensed water temperature detection means 11 and the ambient temperature detection means 12 may be thermistors, temperature sensors, or other suitable devices capable of detecting temperature.
The condensed water temperature at different positions of the heat exchanger 20 may be different, and the condensed water temperature in the heat exchanger 20 in the embodiment of the present invention means the average temperature of the condensed water in the heat exchanger 20. Since the condensed water temperature in the middle of the heat exchanger 20 is relatively close to the average temperature of the condensed water in the whole heat exchanger 20, the refrigerant temperature detecting device 21 is preferably disposed on the surface of the middle of the heat exchanger 20 to detect the condensed water temperature in the heat exchanger 20 as accurately as possible. The refrigerant temperature detecting device 21 may be a thermistor, a temperature sensor, or another suitable device capable of detecting temperature.
The water storage tank 30 may be an open water tank made of any material, i.e., the top of the water storage tank is open, so that the user can take out the condensed water contained in the water storage tank. The water storage tank 30 may also be connected to the toilet through a pipe so as to flush the toilet with the condensed water contained therein.
The control device 40, which is a control part of the air conditioner condensed water recycling device, is connected to the condensed water temperature detection device 11, the ambient temperature detection device 12 and the refrigerant temperature detection device 21, so as to send control commands to the condensed water temperature detection device 11, the ambient temperature detection device 12 and the refrigerant temperature detection device 21 and receive signals containing temperature information sent by the condensed water temperature detection device 11, the ambient temperature detection device 12 and the refrigerant temperature detection device 21. The control instruction may include, for example, an instruction for instructing to start detecting the temperature of the condensed water in the holding water tank 10, an instruction for instructing to start detecting the ambient temperature, and an instruction for instructing to start detecting the temperature of the condensed water in the heat exchanger 20.
The first preset temperature threshold and the second preset temperature threshold are both temperature values preset in the control device 40, and the values thereof are different according to different seasons, different types of heat exchangers, and other different situations. In some embodiments of the present invention, the first preset temperature threshold may be any temperature value between 4 ℃ and 6 ℃ to ensure effective heat exchange between the condensed water and the ambient air. For example, the first predetermined temperature threshold may be 4 ℃, 4.5 ℃, 5 ℃, 5.5 ℃ or 6 ℃. Preferably, when the first preset temperature threshold is 5 ℃, the heat exchange effect can be better achieved, and the temperature of the environmental space can be better improved. In some embodiments of the present invention, the second predetermined temperature threshold may be any temperature between 2 ℃ and 4 ℃ so as to discharge the condensed water in the heat exchanger 20 as soon as possible when the heat exchange between the condensed water and the ambient air cannot be performed effectively, thereby avoiding energy waste. For example, the second predetermined temperature threshold may be 2 ℃, 2.5 ℃, 3 ℃, 3.5 ℃ or 4 ℃. Preferably, the second predetermined temperature threshold is 3 ℃ for better results.
In some embodiments of the present invention, a water amount detecting device 14 for detecting the amount of condensed water in the thermal insulation water tank 10 is further provided. The control device 40 is also configured to activate the condensed water temperature detection device 11 and the ambient temperature detection device 12 when the amount of condensed water in the hot-water tank 10 reaches a first preset water amount threshold value, to detect the temperature of the condensed water in the hot-water tank 10 and the ambient temperature, respectively. That is, in these embodiments, the temperature of the condensate in the holding water tank 10 is detected only when a certain amount of condensate is collected, so that on one hand, the problem of waste and other problems caused by overflowing of the condensate in the holding water tank 10 can be avoided, and on the other hand, the problem that the condensate flowing to the heat exchanger 20 is too little to perform the heat exchange function can be avoided.
Specifically, the water amount detection means 14 is connected to the control means 40 to transmit information on the amount of condensed water in the insulated water tank 10 to the control means 40. The water level detecting device 14 may be a liquid level meter, a float level switch or other suitable device capable of detecting the amount of water. The first preset water threshold is a water value preset in the control device 40, and may be any water value between 0.7 and 0.9 times of the total volume of the heat preservation water tank 10. For example, the first predetermined water threshold may be 0.7 times the total volume of the holding water tank 10, 0.8 times the total volume of the holding water tank 10, or 0.9 times the total volume of the holding water tank 10. Preferably, the first predetermined water threshold may be 0.8 times the total volume of the holding tank 10.
In some embodiments of the present invention, the holding water tank 10 is connected to the heat exchanger 20 through a first pipeline 50, and a first switch valve 51 for switching on and/or off the first pipeline 50 is disposed in the first pipeline 50. The refrigerant inlet and the refrigerant outlet of the heat exchanger 20 are connected by a fourth pipeline 80, and a water pump 81 is disposed in the fourth pipeline 80. The control device 40 is configured to open the first on-off valve 51 to conduct the first pipeline 50 when the difference between the ambient temperature and the temperature of the condensed water in the holding water tank 10 is greater than a first preset temperature threshold, close the first on-off valve 51 after the heat exchanger 20 is filled with the condensed water, and start the water pump 81 to drive the condensed water to circulate in the heat exchanger 20 and the fourth pipeline 80. Therefore, the condensed water can exchange heat with the ambient air for a plurality of times until the temperature of the condensed water in the heat exchanger 20 is close to the ambient temperature, the cold quantity of the condensed water is fully recovered, and the utilization efficiency of the condensed water is improved.
Specifically, the first switching valve 51 is connected to the control device 40 to receive a control command from the control device 40 and perform an opening and closing operation according to the control command, thereby opening and/or blocking the first line 50. The water pump 81 is connected to the control device 40 to receive a control command from the control device 40 and perform start and stop operations according to the control command. The first switching valve 51 is a check valve that allows only the condensed water to flow from the insulated water tank 10 to the heat exchanger 20. The first on-off valve 51 may be a solenoid valve or other valve capable of being controlled to open and close.
Further, a filter 52 is disposed in the first pipe 50 to filter the condensed water flowing to the heat exchanger 20, thereby preventing impurities in the condensed water from corroding the heat exchanger 20 and the water pump 81.
In some embodiments of the present invention, the heat exchanger 20 is connected to the water storage tank 30 through a second pipeline 60, and a second switch valve 61 for switching on and/or off the second pipeline 60 is disposed in the second pipeline 60. The control means 40 is configured to open the second switch valve 61 to conduct the second conduit 60 when the difference between the ambient temperature and the temperature of the condensed water in the heat exchanger 20 is less than or equal to a second preset temperature threshold, so as to allow the condensed water in the heat exchanger 20 to be discharged to the storage tank 30. When the difference between the ambient temperature and the temperature of the condensed water in the heat exchanger 20 is less than or equal to the second preset temperature threshold, the heat exchange efficiency between the condensed water in the heat exchanger 20 and the ambient air is very low, or even effective heat exchange cannot be performed, at this time, the pipeline between the heat exchanger 20 and the water storage tank 30 is conducted, the condensed water in the heat exchanger 20 is discharged into the water storage tank 30 for other purposes, and energy waste caused by the fact that the condensed water is repeatedly driven to flow circularly is avoided.
Specifically, the second switching valve 61 is connected to the control device 40 to receive a control command from the control device 40 and perform an opening and closing operation according to the control command, thereby opening and/or blocking the second line 60. The second switching valve 61 is also a check valve which allows only the condensed water to flow from the heat exchanger 20 to the storage tank 30. The second switch valve 61 may be a solenoid valve or other valve capable of being controlled to open and close.
Further, a filter 62 is disposed in the second pipe 60 to filter the condensed water flowing from the heat exchanger 20 into the water storage tank 30.
In some embodiments of the present invention, the insulated water tank 10 is connected to the water storage tank 30 through a third pipeline 70, and a third on/off valve 71 for opening and/or closing the third pipeline 70 is disposed in the third pipeline 70. The control device 40 is configured to open the third on/off valve 71 when the difference between the ambient temperature and the temperature of the condensed water in the holding water tank 10 is less than or equal to the first preset temperature threshold value to conduct the third pipeline 70, thereby allowing at least a portion of the condensed water in the holding water tank 10 to be directly discharged to the storage tank 30 until the amount of the condensed water in the holding water tank 10 reaches the second preset water amount threshold value. When the difference between the ambient temperature and the temperature of the condensed water in the thermal insulation water tank 10 is less than or equal to the first preset temperature threshold, that is, when the difference between the ambient temperature and the temperature of the condensed water in the thermal insulation water tank 10 is not large, even if the condensed water is introduced into the heat exchanger 20, effective heat exchange can not be performed with the ambient air, at this moment, at least part of the condensed water is directly discharged to the water storage tank 30 for other purposes, so that energy waste caused by starting the heat exchanger to do idle work is avoided, and meanwhile, the phenomenon that the condensed water in the thermal insulation water tank 10 overflows due to too much condensed water can also be avoided.
Specifically, the third switching valve 71 is connected to the control device 40 to receive a control command of the control device 40 and performs an opening and closing operation according to the control command, thereby opening and/or blocking the third line 70. The third on/off valve 71 is also a check valve which allows only the condensed water to directly flow from the insulated water tank 10 to the storage water tank 30. The third on/off valve 71 may be a solenoid valve or other valve capable of being controlled to open and close.
It is understood that when any one of the first to third switching valves 51, 61, 71 is in an open state, the other two are in a closed state.
Further, a filter 72 is disposed in the third pipeline 70 to filter the condensed water directly flowing into the storage tank 30 from the thermal insulation water tank 10.
The second preset water volume threshold is smaller than the first preset water volume threshold. The second preset water threshold is a water value preset in the control device 40, and may be any water value between 0.5 and 0.7 times of the total volume of the heat preservation water tank 10. For example, the second predetermined water amount threshold may be 0.5 times the total volume of the holding water tank 10, 0.6 times the total volume of the holding water tank 10, or 0.7 times the total volume of the holding water tank 10. Preferably, the second preset water threshold may be 0.6 times the total volume of the holding water tank 10.
In some embodiments of the present invention, the upper portion of the thermal insulation water tank 10 is further provided with an overflow hole 15, and the overflow hole 15 is connected to the water storage tank 30 through a fifth pipeline 90, so as to allow the overflowing condensed water to flow into the water storage tank 30 along the fifth pipeline 90 when the condensed water in the thermal insulation water tank 10 overflows from the overflow hole 15 due to overfilling. Further, a filter 91 is disposed on the fifth pipeline 90 to filter the condensed water overflowing from the thermal insulation water tank 10 and flowing into the water storage tank 30.
