Abstract
Description
Technical Field
[0001] The utility model relates to the field of air conditioning equipment technology, in particular to a condensate recovery and treatment device for an air conditioning system. It also relates to an air conditioning system equipped with the condensate recovery and treatment device. Background Art
[0002] Condensate is the liquid water formed after the water vapor in humid air transfers heat to the refrigerant in the evaporator of the air conditioning system and reaches the dew point temperature. In a traditional air conditioning system, a water receiving tray installed below the evaporator is used to collect condensate, and then the collected condensate is directly discharged outdoors. When the humidity is high in summer, the amount of condensate is also large. Due to the relatively low temperature of the condensate itself, it causes a certain degree of waste of cooling capacity.
[0003] At the same time, during the refrigeration process of the air conditioner, the purpose of cooling is achieved through the cooperation of a compressor, an evaporator, a condenser, etc. The air conditioner condenser is a key component in the air conditioning system, and its main function is to change the refrigerant from a gaseous state to a liquid state during the refrigeration cycle. Since the condenser and the condenser fan need to continuously dissipate heat from the refrigerant during the use of the air conditioner, too high an outdoor ambient temperature and blockage outside the condenser will deteriorate the heat dissipation effect of the air conditioner, resulting in a poor refrigeration effect.
[0004] To solve the above problems, a condensate utilization device for a rail vehicle air conditioner is disclosed in the patent with the patent number 201811449616.1. This device monitors the water level in the water receiving tray of the air conditioner evaporator through a liquid level sensor, and uses a variable speed water pump to transport the condensate through a water pipe to a spray head, and atomizes it at the air inlet of the condenser to cool the condenser. This device recovers all the condensate of the air conditioner and uses the low-temperature condensate to improve the cooling effect of the condenser and enhance the overall energy efficiency ratio of the air conditioner. In seasons or regions with high humidity, the amount of condensate recovered in the water receiving tray is large, and the atomized condensate entering the condenser cannot be completely vaporized, resulting in heat loss. The solution of this device is to combine the cooling of the condenser and the cooling of the compressor outlet end, and transport the condensate through a water pipe to a shell-and-tube heat exchanger to cool the high-temperature refrigerant at the compressor outlet. Although this air conditioner condensate utilization device is beneficial to the full utilization of condensate, it also has the problem of complex system structure, and only uses atomized condensate to cool the condenser, and its heat exchange effect is limited. Summary of the Utility Model

[0020] To solve the above technical problems, the basic concept of the second technical solution adopted by the present utility model is:

[0037] Embodiment 1:
[0038] As Figures 1 to 3As shown in the figure, the present utility model provides a condensate recovery and treatment device for an air conditioning system, which includes a condensate collection tank 1 and a heat exchange component 2. The condensate collection tank 1 is connected to the evaporator water pan (not shown in the figure) through a collection pipe 3. The inlet end of the heat exchange component 2 is connected to the collection pipe 3. The condensate can enter the heat exchange component 2 through the collection pipe 3 to exchange heat with the condenser 6, or directly enter the condensate collection tank 1 for collection. The outlet end of the heat exchange component 2 is connected to the condensate collection tank 1, and the condensate after heat exchange with the condenser 6 is finally collected in the condensate collection tank 1 as well.
[0039] As Figure 1 and Figure 2 shown in the figure, in this embodiment, the air conditioning system adopts a split air conditioner unit structure, which consists of an indoor unit and an outdoor unit 4. A refrigerant circulation flow path is formed by connecting the indoor unit and the outdoor unit 4 through refrigerant pipes. An evaporator, an evaporation fan, a throttling element, etc. are installed in the indoor unit, and a condenser 6, a condensing fan, a compressor (not shown in the figure), etc. are installed in the outdoor unit 4. A heat dissipation grille 7 is provided on the housing of the outdoor unit 4 for dissipating heat from components such as the condenser 6 and the compressor. Among them, the condenser 6 can adopt a shell-and-tube heat exchanger, a finned-tube heat exchanger, etc.
[0040] In this embodiment, the condensate recovery and treatment device is integrally installed inside the outdoor unit 4. The collection pipe 3 passes through the housing of the outdoor unit 4 and is connected to the evaporator water pan (not shown in the figure) of the indoor unit through a return pipe (not shown in the figure). The condensate collected in the water pan flows into the collection pipe 3 through the return pipe 5, and then is further collected in the condensate collection tank 1 or enters the heat exchange component 2 to exchange heat with the condenser 6.
[0041] For the convenience of installation, a pipe joint 5 is installed at the top of the collection pipe 3 and is quickly connected to the return pipe through the pipe joint 5. The other end of the return pipe is also connected to the drain outlet of the water pan through a pipe joint.
[0042] For an integrated air conditioning system, a partition is used to separate the indoor side and the outdoor side inside the housing of the air conditioner unit. The device is installed on the outdoor side, and the collection pipe 3 can pass through the partition inside the housing and be directly connected to the evaporator water pan.
[0043] As Figure 2 and Figure 3As shown, in this embodiment, the heat exchange component 2 is in contact connection with the condenser 6, and heat exchange is carried out between the condensed water in the heat exchange component 2 and the refrigerant in the condenser 6 in a direct contact manner. The low-temperature condensed water in the heat exchange component 2 is used to exchange heat with the high-temperature refrigerant in the condenser 6, especially in an outdoor high-temperature environment, to achieve the effect of cooling the condenser 6, realizing the recovery and utilization of the cooling capacity of the condensed water in the air-conditioning system in the refrigeration mode, improving the refrigeration capacity of the air-conditioning system, achieving the purpose of improving the energy efficiency ratio, reducing energy consumption, and also enhancing the high-temperature refrigeration capacity of the air conditioner. The heat exchange between the heat exchange component 2 and the condenser 6 is carried out in a direct contact manner, which is beneficial to improving the heat exchange efficiency between the condensed water and the condenser 6, enabling the condensed water to fully absorb the heat of the refrigerant in the condenser 6.
[0044] In this embodiment, preferably, the heat exchange component 2 includes a shunt pipe 21, a heat exchange pipe 22, and a water outlet pipe 23 connected in sequence. The inlet end of the shunt pipe 21 is connected to the collection pipe 3, and the outlet end of the water outlet pipe 23 is connected to the condensed water collection tank 1. Among them, the heat exchange pipe 22 is in contact connection with the condenser 6 for heat exchange. In this way, the overall structure is simple and compact, which is beneficial to reducing the occupied space of the device in the outdoor unit.
[0045] In this embodiment, further preferably, the heat exchange pipe 22 adopts a spiral coiled structure and is wound around at least part of the outer periphery of the condenser 6. Of course, the heat exchange pipe 22 can also be wound around the entire outside of the condenser 6, and the heat exchange pipe 22 is in direct contact with the condenser 6 for heat exchange. After the heat exchange pipe 22 is spiral coiled, there is a certain gap between the pipes. Especially for the finned-tube condenser 6, it is necessary to ensure the heat exchange amount required between the condenser 6 and the outdoor environment during refrigeration operation.
[0046] Another implementation method is also provided in this embodiment. The heat exchange pipe 22 adopts a parallel tube structure or an S-shaped coil structure and is installed on one side surface of the condenser 6. The heat exchange pipe 22 can be laid flat on the entire side surface of the condenser 6 or only on a part of the side surface of the condenser 6. Specifically, it is laid flat on the side surface of the condenser 6 near the outlet, and is in direct contact with the condenser 6 for heat exchange. Similarly, there is a certain gap between the pipes. Especially for the finned-tube condenser 6, it is necessary to ensure the heat exchange amount required between the condenser 6 and the outdoor environment during refrigeration operation.
[0047] In this embodiment, a drain pipe (not shown in the figure) is also installed at the bottom of the condensed water collection tank 1, and a drain valve is installed on the drain pipe. The drain pipe passes through the bottom plate of the housing of the outdoor unit 4 and communicates with the outside, and is used to directly discharge the condensed water in the condensed water collection tank 1 to the outside. Among them, the drain valve can adopt a manual valve or an automatic valve.
[0048] In this embodiment, the processing device further includes a control unit 8. A first temperature sensor 9 for detecting the temperature of the condenser 6 is installed on the condenser 6. The condenser temperature is the refrigerant temperature at the outlet of the condenser 6. The first temperature sensor 9 is connected to the control unit 8. The control unit 8 controls the on-off of the heat exchange assembly 2 according to whether the collected condenser temperature reaches a threshold value. Specifically, it controls the on-off of the shunt pipe 21. The threshold value includes an upper limit value and a lower limit value. Only when the temperature of the condenser 6 reaches the upper limit value of the threshold, the control unit 8 controls the low-temperature condensed water to flow into the heat exchange pipe 22 to exchange heat with the condenser 6. When the temperature of the condenser 6 is lower than the lower limit value of the threshold, the condensed water no longer enters the heat exchange pipe 22 to exchange heat with the condenser 6, but directly enters the condensed water collection tank 1 through the collection pipe 3 for collection, ensuring that the temperature of the condenser 6 after heat exchange is controlled within a reasonable range.
[0049] In this embodiment, in order to control the on-off of the shunt pipe 21, it is further preferably connected between the collection pipe 3 and the inlet end of the shunt pipe 21 through a three-way valve 10. The three-way valve 10 is connected to the control unit 8 and is used to control the on-off of the shunt pipe 21. When the temperature of the condenser 6 reaches the upper limit value of the threshold, the control unit 8 controls the three-way valve 10 to actuate, connecting the collection pipe 3 and the shunt pipe 21. At this time, part or all of the condensed water will enter the heat exchange pipe 22 through the shunt pipe 21 to exchange heat with the condenser 6. When the temperature of the condenser 6 reaches the lower limit value of the threshold, the control unit 8 controls the three-way valve 10 to actuate, disconnecting the passage between the collection pipe 3 and the shunt pipe 21. All the condensed water flows into the lower condensed water collection tank 1 through the collection pipe 3, ensuring that the temperature of the condenser 6 after heat exchange is controlled within a reasonable range.
[0050] In this embodiment, a second temperature sensor 11 for detecting the temperature of the condensed water and a flow regulating device (not shown in the figure) are installed at the inlet of the heat exchange pipe 21. The flow regulating device and the second temperature sensor 11 are connected to the control unit 8. The control unit 8 controls the flow regulating device to actuate according to the collected condensed water temperature to adjust the amount of condensed water entering the heat exchange pipe 22. The excess condensed water directly enters the lower condensed water collection tank 1 through the collection pipe 3, further ensuring that the temperature of the condenser 6 after heat exchange can be controlled within a reasonable range. The flow regulating device can adjust the water volume by controlling the opening degree or time.
[0051] In this embodiment, it is further preferably that a liquid level sensor (not shown in the figure) is provided in the condensed water collection tank 1. The liquid level sensor is connected to the control unit 8, and the drain valve on the drain pipe is also connected to the control unit 8. When it is detected that the water volume in the condensed water collection tank 1 reaches the set water level, the control unit 8 controls the drain valve to open and drain the water in the condensed water collection tank 1, realizing automatic control.
[0052] In this embodiment, it is further preferably that the control unit 8 is integrated in the controller of the air-conditioning system (not shown in the figure), which is beneficial to simplifying the structure of the air-conditioning system and reducing costs.
[0053] The working principle of the device is as follows:
[0054] In the refrigeration working mode of the evaporator, the generated condensate is first collected in the water receiving tray. The condensate in the water receiving tray is then transmitted through the return pipe to the collecting pipe 3 in the outdoor unit 4. After the first temperature sensor 9 detects that the temperature of the condenser 6 has risen to the upper limit of the threshold value, the control unit 8 controls the three-way valve 10 to actuate and open. The condensate is transmitted through the shunt pipe 21 to the inside of the heat exchange pipe 22 to start cooling the condenser 6. During this process, the control unit 8 further controls the flow regulating device to act according to the temperature of the condensate detected by the second temperature sensor 11 to adjust the amount of condensate entering the heat exchange pipe 22. The heat-exchanged condensate then enters the inside of the lower condensate collection tank 1 through the water outlet pipe 23 to complete the cooling work of the condenser 6. Finally, all the condensate in the condensate collection tank 1 is discharged to the outside through the drain pipe.
[0055] Embodiment 2:
[0056] The difference from Embodiment 1 is that in this embodiment, the heat exchange assembly 2 is installed on the air inlet side of the condenser 6, and the heat exchange between the heat exchange assembly 2 and the condenser 6 is indirectly carried out in a non-contact manner. This structure is beneficial to the transformation on the basis of the existing condenser 6.
[0057] Specifically, the heat exchange pipe 22 adopts a parallel tube structure or an S-shaped coil structure and is installed at intervals on the air inlet side of the condenser 6, with a certain gap between it and the condenser 6. Under the action of the condensate fan, the outdoor air first passes through the heat exchange pipe 22 and exchanges heat with the low-temperature condensate in the heat exchange pipe 22, so that the temperature of the air before entering the condenser 6 is reduced. The air with the reduced temperature then exchanges heat with the condenser 6 to cool the condenser 6.
[0058] The control method in this embodiment is the same as that in Embodiment 1. In the refrigeration working mode of the evaporator, the generated condensed water is first collected in the water receiving tray. The condensed water in the water receiving tray is then transmitted through the return pipe to the collecting pipe 3 inside the outdoor unit 4. After the first temperature sensor 9 detects that the temperature of the condenser 6 has risen to the upper limit of the threshold value, the control unit 8 controls the three-way valve 10 to actuate and open. The condensed water is transmitted through the shunt pipe 21 to the inside of the heat exchange pipe 22. Under the action of the condensation fan, the condenser 6 starts to be cooled. During this process, the control unit 8 then controls the flow regulating device to act according to the temperature of the condensed water detected by the second temperature sensor 11, and adjusts the amount of condensed water entering the heat exchange pipe 22. The heat-exchanged condensed water then enters the inside of the lower condensed water collection tank 1 through the water outlet pipe 23, completing the cooling work of the condenser 6. Finally, all the condensed water in the condensed water collection tank 1 is discharged outdoors from the drain pipe.
[0059] Embodiment 3:
[0060] This embodiment provides an air-conditioning system, in which the above-mentioned condensed water recovery and treatment device is installed.
[0061] Specifically, for a split air-conditioning system, it is composed of an indoor unit and an outdoor unit 4. A refrigerant circulation flow path is formed by connecting the indoor unit and the outdoor unit 4 through refrigerant pipes. An evaporator, an evaporation fan, a throttling element, etc. are installed in the indoor unit, and a condenser 6, a condensation fan, a compressor (not shown in the figure), etc. are installed in the outdoor unit 4. A heat dissipation grille 7 is provided on the housing of the outdoor unit 4. The condensed water recovery and treatment device is integrally installed inside the outdoor unit 4. The collecting pipe 3 passes through the housing of the outdoor unit 4 and is connected to the water receiving tray of the evaporator of the indoor unit (not shown in the figure) through a return pipe (not shown in the figure). The condensed water collected in the water receiving tray flows into the collecting pipe 3 through the return pipe 5, and is further collected in the condensed water collection tank 1 or enters the heat exchange assembly 2 to exchange heat with the condenser 6.
[0062] For an integrated air-conditioning system, the indoor side and the outdoor side are separated by a partition in the housing of the air-conditioning unit. The condensed water recovery and treatment device is integrally installed on the outdoor side, and the collecting pipe 3 can directly access the water receiving tray of the evaporator through the partition inside the housing.
[0063] The condensed water recovery and treatment device of the air-conditioning system provided by the present utility model has the following advantages:
[0064] 1. Through the provided heat exchange assembly, the condensed water that was originally discharged outdoors is diverted into the heat exchange assembly to cool the condenser, effectively realizing the cold quantity recovery of the condensed water, improving the heat exchange effect of the condenser, further enhancing the refrigeration capacity of the air-conditioning system, increasing the energy efficiency ratio of the air-conditioning system, and reducing the energy consumption of the air-conditioning system.
[0065] 2. By directly contacting the heat exchange component with the condenser, the device exchanges heat with the condenser in a direct contact manner, or under the action of the condensation fan, exchanges heat in a non-contact indirect heat exchange manner, making the overall structure of the device simpler and easier to transform on the basis of the existing air conditioning system with low transformation cost.
[0066] 3. Through the first temperature sensor set in the device, the surface temperature of the condenser is monitored in real time. When the temperature of the condenser begins to rise, the condensed water is diverted into the interior of the heat exchange component to cool the condenser, enabling temperature monitoring and control of the condenser and timely providing the required cooling capacity, thereby ensuring the stability of the working state of the air conditioning system.
[0067] The above are only the preferred embodiments of the present invention, and there is no limitation to the present invention in any form. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art of this patent, without departing from the scope of the technical solution of the present invention, can make some changes or modifications to the above-mentioned technical content as equivalent embodiments of equivalent changes.
