Description

[Technical Field]

[0001] The present invention relates to the technical field of air conditioning, and more particularly to a cooling and heating device for secondary recovery of condensed water in an air conditioner. [Background technology]

[0002] Conventional air conditioners typically use an air-cooling method to dissipate heat, which requires a large amount of energy to drive a fan to cool the room. In extremely hot weather, the air-cooling method is not effective in dissipating heat, and the Air Conditioner Master frequently trips the high-temperature shutdown protection, resulting in poor indoor cooling performance.

[0003] Currently, some large air conditioning systems are specially designed with devices that use domestic water (such as tap water) to dissipate heat. These devices achieve heat dissipation and temperature reduction by directing tap water through pipes near the condenser and atomizing it with a nozzle to spray it onto the surface of the condenser, but this method actually has low efficiency in dissipating heat and reducing temperature.

[0004] However, using tap water to cool an air conditioner results in a significant waste of water resources. At the same time, conventional cooling devices using tap water cannot adjust the temperature of tap water in winter to heat the air conditioner for condensation, defrosting, and snow removal. Therefore, there is an urgent need to propose a completely new air conditioner cooling device that uses condensed water generated during air conditioner operation to cool or heat the air conditioner, thereby enabling air conditioner cooling, heat dissipation, defrosting, and snow removal in extreme weather (too cold or too hot) while saving water resources.

DETAILED DESCRIPTION OF THE INVENTION

[0025] In order to clarify the objectives, technical solutions and advantages of the embodiments of the present invention, the technical solutions in the embodiments of the present invention are clearly and fully described. It is clear that the described embodiments are only some of the embodiments of the present invention, and do not represent all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without the need for creative work shall fall within the scope of protection of the present invention.

[0026] The embodiment of the present application provides a cooling and heating device for secondary recovery of air conditioner condensate, thereby solving the problems of prior art secondary circulation devices for air conditioner condensate, which waste water resources and have a single function, and achieving the goal of diversifying the use of air conditioner condensate at different ambient temperatures.

[0027] The overall concept of the technical solutions in the embodiments of the present application to solve the above technical problems is as follows:

[0028] In prior art, the circulating use of air conditioner condensate is limited to spraying it on the surface of the condenser to assist in heat dissipation and temperature reduction. However, after being used for heat dissipation and temperature reduction, the condensate is discarded, resulting in a significant waste of water resources. At the same time, the circulating use of air conditioner condensate in prior art is also limited to using the condensate to dissipate heat and temperature reduction from the condenser. However, in cold winters, when the ambient temperature is too low, frost or snow accumulates on the surface of the outdoor unit, preventing effective heat dissipation. Currently, there is no technology that uses condensate to remove snow or defrost from the outdoor unit. To address this issue, the proposed technology allows condensate to be cooled (or heated) when the ambient temperature is high (or low), and then applied to the aluminum foil heat dissipation fins of the outdoor unit by spraying, immersion, or other methods to reduce temperature and heat reduction (or remove snow or defrost). At the same time, the condensed water after being used for defrosting and snow removal by heat dissipation, temperature drop or temperature rise is recovered again through the circulating return pipe and continuously circulated for the above-mentioned heat dissipation, defrosting and snow removal processes.The technical solution of this application utilizes the condensed water generated by the air conditioner itself, improves the circulating efficiency of the air conditioner condensed water, saves water resources, realizes the use of condensed water in multiple scenarios in hot and cold weather, enriches the condensed water circulating function, and extends the service life of the air conditioner.

[0029] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the drawings and specific embodiments.

[0030] 1 to 6, the cooling / heating device for secondary recovery of air conditioner condensate proposed in the present application includes a recovered water storage tank 1, a water pump 2, a controller 3, and a condensate circulation pipe 4.

[0031] Here, the condensed water circulation pipeline 4 includes a water inlet pipe 41 and a circulating return pipe 42. The water inlet end of the water inlet pipe 41 is connected to the recovered water storage tank 1 via the water pump 2, and the water outlet end of the water inlet pipe 41 is connected to a temperature-lowering / heating component 5 for lowering or heating the temperature of the air conditioner outdoor unit 8. The water inlet end of the circulating return pipe 42 is connected to a water collector 6 for collecting the condensed water after being used to lower or heat the temperature of the air conditioner outdoor unit 8. The water outlet end of the circulating return pipe 42 is connected to the recovered water storage tank 1, and returns the condensed water after being used to lower or heat the temperature of the air conditioner outdoor unit 8 to the recovered water storage tank 1 again.

[0032] The recovered water storage tank 1 is connected to the condensate recovery device of the air conditioner, specifically to the condensate recovery pipe of the air conditioner, and is used to collect and store condensate generated during operation of the air conditioner. The water pump 2 is used to extract the condensate water from the recovered water storage tank 1 and send it to the water inlet pipe 41. The controller 3 is electrically connected to the water pump 2 and a power source, and is used to control the start and stop of the water pump 2.

[0033] The cooling / heating component 5 is used to cool / dissipate heat or defrost / remove snow from the air conditioner outdoor unit 8 by using cooled or heated condensed water depending on the ambient temperature where the air conditioner outdoor unit 8 is placed.

[0034] In one embodiment of the present application, in order to protect components such as the water pump 2 and controller 3, the cooling / heating device for secondary recovery of air conditioner condensate further includes a box 7, and it is preferable that the components such as the recovered water storage tank 1, the water pump 2, and the controller 3 are installed in a rationally distributed manner within the box 7. In this case, it is preferable that the condensate circulation pipe 4 extends to the outside of the box 7 through a through-hole opened in the box 7 and is connected to the corresponding piping of the cooling / heating component 5.

[0035] The cooling / heating component 5 is mounted on the air conditioner outdoor unit 8 and is used for heat dissipation / cooling or defrosting / snow removal of the aluminum foil heat dissipation fins of the air conditioner outdoor unit 8. In the technical solution of the present application, the specific shape and mounting manner of the cooling / heating component 5 are not limited, and may be a condensed water carrying copper pipe 51, an infiltrator 52, a spray head 53, a dripping cooling pipe 54, an atomizer (not shown), etc. Other parts or structures that use condensed water to cool or heat the air conditioner outdoor unit 8 based on the principle of cooling by water cooling are also within the scope of protection of the present application.

[0036] In one preferred embodiment, as shown in FIG. 1 , the cooling / heating component 5 is a condensed water carrying copper pipe 51. A plurality of the condensed water carrying copper pipes 51 are fitted into the aluminum foil heat dissipation fins of the air conditioner outdoor unit 8. The outlet end of the water inlet pipe 41 is connected to the inlet ends of all the condensed water carrying copper pipes 51, and the inlet end of the circulating return pipe 42 is connected to the water collector 6, which is connected to the outlet ends of all the condensed water carrying copper pipes 51. The cooled or heated condensed water is pressurized by the water pump 2 and enters the condensed water carrying copper pipe 51 through the water inlet pipe 41, then flows out of the outlet of the condensed water carrying copper pipe 51 and enters the water collector 6, then enters the circulating return pipe 42, and finally returns to the recovered water storage tank 1. During this process, the cooled or heated condensed water either absorbs heat from the aluminum foil heat dissipation fins or increases their temperature, thereby achieving cooling, heat dissipation, defrosting, and snow removal from the aluminum foil heat dissipation fins.

[0037] Furthermore, to facilitate actual installation, the condensed water transport copper pipe 51 is a single, continuously bent U-shaped pipe, and is laid so as to be uniformly inserted between the aluminum foil heat dissipation fins. The outlet end of the condensed water transport copper pipe 51 is connected to the water collector 6.

[0038] Furthermore, when the condensed water conveying copper pipe 51 is selected as the temperature-lowering / heating component 5, the outlet end of the condensed water conveying copper pipe 51 and the water collector 6 can be installed as one unit, or the water collector 6 can be omitted and the condensed water flowing out from the outlet of the condensed water conveying copper pipe 51 can be directly introduced into the circulating return pipe 42 and returned to the recovered water storage tank 1.

[0039] In another embodiment, as shown in FIG. 2, the cooling / heating component 5 is an infiltrator 52. A plurality of infiltrators 52 are attached and fixed to the top ends of the aluminum foil fins, or are attached to the edge of the outdoor unit and positioned directly above the aluminum foil fins. The outlet end of the water inlet pipe 41 is connected to the inlet ends of all the infiltrators 52. Specifically, as shown in FIG. 3, the infiltrator 52 includes a water inlet and a stainless steel stopper, and a water-absorbing sponge is fixedly attached to the bottom of the stainless steel stopper. The cooled or heated condensed water is pressurized by the water pump 2 and enters the infiltrator 52 through the water inlet pipe 41. It then slowly seeps out and flows over the aluminum foil fins, removing heat from the aluminum foil fins or increasing their temperature, thereby achieving cooling / heating or defrosting / snow removal from the aluminum foil fins. On the other hand, the condensed water after being used to cool or heat the aluminum foil heat dissipation fins flows along the aluminum foil heat dissipation fins into the water collector 6 and returns to the recovered water storage tank 1 through the circulation return pipe 42 connected to the water collector 6. In actual installations, the position of the water collector 6 is generally set higher than the circulation return pipe 42 so that the condensed water after use can easily return to the recovered water storage tank 1.

[0040] In yet another embodiment, the cooling / heating component 5 is a spray head 53, the specific structure of which is shown in FIG. 4 . Multiple spray heads 53 are mounted at different positions around the aluminum foil heat dissipation fins via supports. The outlet ends of water inlet pipes 41 are connected to all of the spray heads 53, and the inlet ends of circulating return pipes 42 are connected to a water collector 6 located below the aluminum foil heat dissipation fins for collecting the condensed water recovered after spraying. The cooled or heated condensed water is pressurized by water pump 2 and enters spray head 53 through water inlet pipe 41. The condensed water is then sprayed from spray head 53 to cool or heat the aluminum foil heat dissipation fins. After being used to cool or heat the aluminum foil heat dissipation fins, the condensed water flows along the aluminum foil heat dissipation fins into water collector 6 and returns to the recovered water storage tank 1 through circulating return pipe 42 connected to water collector 6. During this process, when the cooled or heated condensed water is sprayed onto the aluminum foil heat dissipation fin, it either removes heat from the aluminum foil heat dissipation fin or increases the temperature of the aluminum foil heat dissipation fin, thereby achieving cooling, heat dissipation, defrosting, and snow removal from the aluminum foil heat dissipation fin.

[0041] In another embodiment, the temperature-lowering / heating component 5 may be a dropping temperature lowering pipe 54 or an atomizer. When the temperature-lowering / heating component 5 is the dropping temperature lowering pipe 54, the specific installation method thereof and the specific connection method thereof with the condensate circulation pipe 4 can refer to the embodiment when the temperature-lowering / heating component 5 is the permeator 52, and therefore will not be described again here. The specific structure of the dropping temperature lowering pipe 54 is as shown in FIG. 5.

[0042] When the cooling / heating component 5 is an atomizer (not shown), the specific installation method thereof and the specific connection method thereof with the condensed water circulation pipe 4 can be referred to the embodiment when the cooling / heating component 5 is a spray head 53, and therefore will not be described again here.

[0043] Furthermore, to further improve the cooling / heating or defrosting / snow-removing effects of the aluminum foil heat dissipation fins, in a specific implementation, the cooling / heating components 5 may be any combination of multiple types, such as a condensate transport copper pipe 51, an infiltrator 52, a spray head 53, a dripping cooling pipe 54, and an atomizer. That is, two, three, or multiple types of cooling / heating components 5 may be simultaneously selected and combined to improve the cooling / heating or defrosting / snow-removing effects. When multiple types of cooling / heating components 5 are combined, the above specific installation methods and pipe connection methods may be referenced.

[0044] Since the temperature of the condensate may not necessarily be suitable for cooling or heating, in order to improve the efficiency of defrosting and snow removal by cooling, heat dissipation, or heating of the air conditioner outdoor unit 8, in one embodiment, the cooling / heating device for secondary recovery of air conditioner condensate proposed herein further includes a temperature control component 9 for adjusting (i.e., cooling or heating) the temperature of the condensate in the recovered water storage tank 1. The temperature control component 9 is electrically connected to the controller 3 via a temperature controller 13, and further controls the operating state of the temperature control component 9 by controlling the on / off of the current. Here, the temperature control component 9 includes a heater provided at the bottom of the recovered water storage tank 1. Preferably, the heater is an electric heating wire, a heat bar, a heat pipe, or the like.

[0045] In any of the above embodiments, the controller 3 is a smart spray atomization controller with model number S-2000. The controller 3 has a built-in transformer and can perform voltage conversion according to actual needs. The circuit diagram of the control system in which the controller 3 controls the cooling / heating device for secondary recovery of air conditioner condensate in the above embodiment to perform defrosting / snow removal by cooling / heating or heating is shown in Figure 7.

[0046] In actual operation, after the air conditioner master is activated, the air conditioner outdoor unit 8 begins operation, and only then does it need to be cooled, radiated, or heated to defrost and remove snow. Furthermore, if the ambient temperature where the air conditioner outdoor unit 8 is located is appropriate, cooling or heating the outdoor unit is not necessary. To save energy, in one preferred embodiment, as shown in FIG. 6 , the cooling and heating device for secondary recovery of air conditioner condensate further includes a master operating status monitoring module 10 electrically connected to the controller 3. The master operating status monitoring module 10 feeds back the monitored master operating status data to the controller 3, which then sends a signal to control the operating status of the temperature control component 9. Here, the master operating status monitoring module 10 includes a master start / stop monitoring unit and an outdoor unit temperature detection unit. The master start / stop monitoring unit is used to monitor the operating status of the air conditioner master, i.e., the start and stop of the air conditioner master, and the outdoor unit temperature detection unit is used to monitor the ambient temperature where the outdoor unit is located. Both the master start / stop monitoring unit and the outdoor unit temperature detection unit are electrically connected to the controller 3. Specifically, the master start / stop monitoring unit includes a current transformer, specifically a current transformer M3050, for detecting the start and stop of the air conditioner compressor. The outdoor unit temperature detection unit includes a temperature detection sensor for monitoring the ambient temperature, which is electrically connected to the temperature controller 13. The specific model number of the temperature detection sensor is not limited here, and it is sufficient if it can achieve the temperature detection function.

[0047] In one preferred embodiment, the recovered water storage tank 1 is also provided with a water level sensor 11 and a drain valve 12, both of which are connected to the controller 3. When the water level in the tank rises and exceeds a preset maximum value for the recovered water storage tank 1, a drain signal is activated, and the drain valve 12 is opened to drain excess condensed water from the tank, thereby preventing excessive condensed water from overflowing and damaging the air conditioning device. Specifically, the water level sensor 11 is preferably a tank level gauge.

[0048] Furthermore, to prevent the temperature control component 9 from continuing to operate when the water level in the recovered water storage tank 1 is too low, thereby preventing damage to the recovered water storage tank 1 and other related equipment, the recovered water storage tank 1 is further provided with an anti-dry-burn protection level gauge 14 electrically connected to the controller 3.

[0049] The operating principle of the cooling / heating device for secondary recovery of air conditioner condensate according to the present invention is as follows. (1) In summer, when the ambient temperature where the Air Conditioner Master is placed is high and it is necessary to lower the evaporator temperature, After the air conditioner starts, the current transformer detects the start of the air conditioner compressor and simultaneously sends a signal to the main power relay KA, activating the condensate recovery device in the air conditioner and starting to collect condensate. When the condensate in the tank reaches a preset height, the controller 3 controls the start and operation of the built-in circulating water pump 2 to extract the condensate and send it through the water inlet pipe 41 to the water inlets of the cooling and heating components 5 (e.g., condensate transport copper pipe 51, infiltrator 52, spray head 53, dripping cooling pipe 54, atomizer, etc.), where it circulates heat and cools the air conditioner's outdoor unit's heat dissipation fins.

[0050] After the air conditioner outdoor unit stops, a power-off signal is sent from the current transformer, the power supply relay KA is turned off, the total power supply to the condensate recovery system is cut off, the condensate recovery system stops operating, the operation of the equipment stops, and at the same time, the water pump 2 also stops operating. The condensate that has absorbed heat from the evaporator enters the circulating return pipe 42 and returns to the recovered water storage tank 1.

[0051] The heat bar built into the recovered water storage tank 1 is controlled by a temperature controller. In the summer, the ambient temperature detected by the temperature controller is always above 10°C (the control temperature setting of the temperature controller is set to 10°C), so the temperature controller is always in a shut-off state and the electric heat bar is always in a power-off state.

[0052] (2) In winter, when the ambient temperature of the air conditioner master is low and it is necessary to raise the temperature of the evaporator to remove snow and frost, After the air conditioner's outdoor unit starts up, the current transformer detects that the air conditioner master has started up and sends a signal to the main power relay KA, turning on the circuit power and outputting 12V DC voltage and current from the condenser's built-in switch power supply. When the water level in the recovered water storage tank 1 reaches a preset value, the electric heat bar starts up and heats the condensed water. When the tank temperature monitor detects that the condensed water temperature has reached its maximum temperature of 50°C (the preset heating temperature is 50°C), the electric heat bar turns off, and the water pump 2 starts up to begin heat circulation. The heated condensed water is extracted and sent through the water inlet pipe 41 to the water inlet of the cooling / heating component 5, where it is heated to the heat dissipation fins of the air conditioner's outdoor unit for defrosting and snow removal.

[0053] In addition, when the water level sensor 11 monitors that the water level in the tank has risen and exceeded a preset maximum value relative to the water level in the recovered water storage tank 1, a drain signal is activated and the drain valve 12 is opened to drain excess condensed water from the tank.

[0054] In summary, the present invention has the following advantageous effects compared to the prior art.

[0055] 1. The proposed cooling / heating device for secondary recovery of air conditioner condensate includes a recovered water storage tank, a water pump, a controller, and a condensate circulation line. The condensate circulation line includes a water inlet pipe and a circulating water return pipe. The water inlet end of the water inlet pipe is connected to the recovered water storage tank via a water pump, the water outlet end of the water inlet pipe is connected to a cooling / heating component for cooling or heating the air conditioner outdoor unit, the water inlet end of the circulating water return pipe is connected to a water collector for collecting the condensate cooled or heated by the air conditioner outdoor unit, and the water outlet end of the circulating water return pipe is connected to the recovered water storage tank, and the water pump is electrically connected to the controller. The proposed cooling / heating device for secondary recovery of air conditioner condensate cleverly utilizes the condensate generated by the air conditioner itself, increasing the number of times the air conditioner condensate is recycled, saving water resources while selectively cooling or heating the condensate according to the outdoor environment, thereby realizing cooling / heating or defrosting / snow removal for the air conditioner outdoor unit and enhancing the recycling function of condensate.

[0057] 3. The cooling and heating components of the cooling and heating device for secondary recovery of air conditioner condensate proposed in this application use a master operating status monitoring module to link the start and stop of the master, the ambient temperature where the master is placed, and the circulating use of condensate, which is more scientific and rational, not only saving energy but also extending the service life of the air conditioner.
