Description

Technical Field

[0001] This invention relates to a fresh air conditioning structure and control system that utilizes residual cooling from condensate, belonging to the field of air conditioning systems. Background Technology

[0002] On the one hand, in order to ensure indoor air quality and dilute carbon dioxide concentration, fresh air needs to be supplied from the outside to replace the stale indoor air. This fresh air is usually at a higher temperature, requiring additional cooling energy.

[0003] On the other hand, the low-temperature condensate water of traditional split air conditioners is usually discharged directly without being recycled. The temperature of the condensate water is generally 11-13℃, which is far lower than the ambient temperature. It has a good cooling capacity advantage, and direct discharge results in energy waste. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a fresh air conditioning structure and its control system that utilizes the residual cooling of condensate water to solve the problem.

[0016] When the water temperature exceeds the set high value, the solenoid valve of the drain pipe is opened to drain the condensate in the water tank, and then the solenoid valve is closed to continue storing water.

[0024] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0025] Please see Figure 1 The present invention provides a fresh air conditioning structure that utilizes residual cooling of condensate: the structure includes an air conditioner with a condensate pipe A; the air conditioner includes an indoor unit 1 placed indoors and an outdoor unit 2 placed outdoors; wherein the condensate pipe A is connected to the indoor unit 1;

[0026] A one-way valve is installed at the outlet of the condensate pipe A and connected to a water tank 3 for water storage; the inner wall of the water tank 3 is filled with a heat insulation structure, which can be made of materials such as foam plastic or stainless steel and installed on the inner wall of the water tank 3. Furthermore, a double wall can be used to form a vacuum layer to improve the heat insulation effect of the condensate in the water tank 3.

[0027] A fan 4 is installed outdoors. The air outlet of the fan 4 is connected to the water tank 3, and the airflow will come into contact with the condensate in the water tank 3 and be heated. The fan 4 is connected to the water tank 3 through an air supply pipe B. The air supply pipe B is U-shaped and a check valve 6 is installed at the end to prevent fresh air from flowing back. The air supply pipe B is connected to the water tank 3, and the height of the air outlet of the air supply pipe B is lower than the height of the condensate liquid level. The fresh air drawn in by the fan 4 goes to the water tank 3 through the air supply pipe B. The fresh air comes into contact with the condensate and is heated, thus reducing the temperature of the fresh air. The water tank 3 has an exhaust pipe C for the fresh air to flow out, and the exhaust pipe C is connected to the indoor area.

[0028] The water tank 3 has a drain pipe D for discharging condensate, and the drainage volume is controlled by an electric valve 9 on the drain pipe D.

[0029] Please see Figure 2 A drying assembly 5 is installed on the exhaust pipe C, which is used for adjustable dehydration of the air inside the exhaust pipe C. The drying assembly 5 includes a circular housing 51, a rotating shaft 52 located at the axis of the housing 51, and several baffles 53 fixed on the rotating shaft 52. Each baffle 53 has a different absorbent cotton 54 fixed to its front side. A chamber is formed between adjacent baffles 53, and the air inlet end 55 and the air outlet end of the housing 51 are respectively placed in this chamber. The rotating shaft 52 is connected to a driving component to rotate the baffles 53 so as to change the chamber in which the air inlet end 55 and the air outlet end are located. The air inlet end 55 corresponds to the absorbent cotton 54 to adjust the airflow. The process involves dehydration; the drive component uses a servo motor; different absorbent cotton 54 can be made of the same or different materials. If the same material is used, the thickness of the absorbent cotton 54 needs to be changed so that the distance the fresh air passes through the absorbent cotton 54 is different to achieve different degrees of dehydration. The absorbent cotton 54 can be purchased directly on the market, so its type will not be described in detail. Of course, to achieve the sustainability of the component, the absorbent cotton 54 can be glued to the wind deflector 53. After a certain period of use, the cabinet door on the housing 51 can be opened for replacement; the air inlet 55 and the air outlet 51 are respectively connected to the exhaust pipe C to form the air inlet 55, and the air outlet 55 is connected to the room.

[0030] Please see Figure 3The water tank 3 has a cleaning assembly in the middle; the cleaning assembly includes a cleaning disc 31 installed on the inner wall of the water tank 3, a filter cloth bag 32 placed at the bottom of the cleaning disc 31, a memory metal wire 33 for supporting the filter cloth bag 32, and a column 34 connecting the filter cloth bag 32; the shaft of the cleaning disc 31 is a hollow straight rod, and the bottom of the straight rod is an inclined filter screen; the memory metal wire 33 extends outward and is fixed on the filter cloth bag 32 to form the skeleton of the filter cloth bag 32, thereby making the filter cloth bag 32... 2. The column 34 is unfolded to cover the bottom of the cleaning tray 31; an end cap 35 is fixed to the end of the column 34 and threadedly connected to the straight rod of the cleaning tray 31; during initial use, the filter cloth bag 32 can be fixed to the column 34 (the fixing method can be that the column 34 is threadedly connected to the filter cloth bag 32, and of course, the filter cloth bag 32 is provided with a connector at the axis for threaded connection of the column 34), and a memory metal wire 33 made of nickel-titanium alloy is fixed on the filter cloth bag 32 to form a skeleton, and then the filter cloth bag 32 is folded up towards the cleaning tray 31. The hollow rod is inserted, and when the filter cloth pocket 32 ​​is at the bottom of the cleaning tray 31, the memory metal wire 33 will unfold the filter cloth pocket 32 ​​to cover the bottom of the cleaning tray 31. Then, the column 34 is screwed onto the hollow rod of the cleaning tray 31 through the end cap 35 to fix it in place. To achieve cleaning without opening the tank, the condensate in the water tank 3 is drained first, then the end cap 35 is unscrewed and the column 34 is pulled out (the filter cloth pocket 32 ​​will be pulled out along with it). Then, water is added to the water tank 3 to remove the water that fell out during the extraction. Impurities are rinsed and discharged from drain pipe D, and then a new filter cloth bag 32 is reinstalled. The purpose of setting up the filter cloth bag 32 is to filter the fresh air introduced by the fan 4. Although the fan 4 is also equipped with a filter screen, the mesh of this filter screen is generally relatively large and can only filter some large impurities. However, the filter cloth bag 32 can filter the fresh air finely, so that small particles of impurities are adsorbed on the filter cloth bag 32. Of course, the installation height of the filter cloth bag 32 should be greater than the height of the air supply pipe B connecting to the water tank 3.

[0031] Please see Figure 4 A control system for a fresh air conditioner utilizing residual cooling from condensate water includes a structure for the fresh air conditioner, a controller 11, a CO2 concentration detection sensor 10 installed indoors, a liquid level sensor 7 and a temperature sensor 8 acting on a water tank 3, and an electric valve 9 installed on a drain pipe D; the CO2 concentration detection sensor 10, the liquid level sensor 7, the temperature sensor 8, the electric valve 9, the fan 4, and the driving components in the drying assembly 5 are all controlled by the controller 11.

[0032] Preferably, the CO2 concentration detection sensor 10 detects the indoor CO2 concentration; the liquid level sensor 7 detects the water level in the water tank 3; and the temperature sensor 8 detects the temperature of the condensate in the water tank 3.

[0033] CO2 concentration sensor 10 feeds back the indoor CO2 concentration to controller 11. When the CO2 concentration is higher than the set high value (1000PPM, i.e., 0.1%) and the water level in water tank 3 is higher than the set value (80%, the default value is adjustable), fan 4 is started to introduce fresh air until the indoor CO2 concentration is lower than the set low value or the water temperature is higher than the set high value (600ppm, the default value is adjustable), then fan 4 is turned off to stop air supply.

[0034] When the water temperature is higher than the set high value (20℃, the default value is adjustable), open the solenoid valve of drain pipe D to drain the condensate in water tank 3, and then close the solenoid valve to continue storing water.

[0035] The electrical components electrically connected to the controller described in this patent are conventional devices that can be purchased directly from the market. Therefore, their models and types will not be described in the specification. The circuit control method can be implemented by those skilled in the art through simple programming as required.
