Improves performance and reduces electricity consumption of domestic gas coolers

Abstract

Summary of the invention: This invention is in the field of home cooling systems and gas cooler accessories and provides an innovative method for reducing energy consumption and increasing cooling efficiency through condenser cooling. In this system, distilled water resulting from the operation of the internal unit of the gas cooler is collected in a tank and, after detecting the appropriate level by a normal open float, is sprayed onto the condenser in the form of a fine mist by a 12-volt diaphragm pump and a digital timer at defined time intervals. This process reduces the condenser temperature and improves the compressor heat exchange. The system is independent of city water and can be installed and operated without changing the main circuit of the cooler.

Description

Description of the invention Title of the invention Improves performance and reduces electricity consumption of home air conditioners Technical background of the relevant invention The present invention relates to the field of home cooling equipment, and in particular to systems for optimizing the performance of air conditioners. The subject of this invention is the design and manufacture of a device that, by recycling distilled water from the internal panel of the air conditioner, cools the condenser and thus reduces electrical energy consumption. Technical problem and stating the objectives of the invention In tropical regions of the country, especially in southern Iran, gas air conditioners account for a major portion of household electricity consumption. Increasing ambient temperature reduces condenser efficiency, increases compressor amperage, and increases electricity consumption. On the other hand, gas air conditioners produce a certain amount of distilled water from the humidity in the indoor air during operation, which is often drained through a drain hose. This usable water source is usually wasted. The objectives of this invention are: Reducing the electricity consumption of gas air conditioners through local condenser cooling, Reuse of water from internal condensation, Reducing the thermal load of the compressor without changing the main structure of the device, Easy installation and no need for specialized repair or external water supply A description of the state of the prior art and the history of developments related to the claimed invention. In the field of improving the efficiency of gas air conditioners and reducing energy consumption, several methods have been introduced for cooling the condenser. One of the most common methods is the use of water spraying on the condenser radiator to reduce the coil temperature and reduce the compressor power consumption through surface evaporation. This approach has been studied in a number of foreign patent documents and scientific articles. One well-known example is US Patent 7,544,011, entitled Water Mist Condenser Cooling System. In this invention, a series of misting nozzles are installed around the condenser to reduce the surface temperature of the radiator by continuously spraying water. Despite the initial efficiency of this method, the system requires a permanent connection to a municipal water or pressurized water source and lacks any water recycling mechanism or intelligent control of the spray rate. In addition, the use of ordinary water causes deposits and gradual corrosion of the condenser fins and tubes, creating maintenance problems in the long term. Providing a solution to an existing technical problem along with an accurate, sufficient, and integrated description of the invention This device consists of a few simple components, including: 1- 12 volt DC diaphragm pump 2- Timer 3- Water level sensor (float) 4- 12 volt 3 amp adapter 5- Water tank 6- Mist nozzle 7- Mist hose 8- Mist drip catcher The device works in such a way that 12V DC power from the adapter is connected to the pump in two ways, one is the timer and the other is the water level sensor (float), (the timer also uses a 12V power adapter for power). The float is installed on the tank as a normally open (NO), if any of the sensors, whether the timer or the float, operate, the pump turns on. We adjust the timer settings according to the environmental conditions (for example, how hot the outside air is). For example, for Ahvaz, it should be activated every 5 minutes for 10 seconds, and when the timer is activated, the pump will turn on for 5 seconds. The float switch also turns on the pump when it is closed until the switch is turned off again. The cooler's basin shell is attached to the top of the tank, and the water that the cooler's inner panel absorbs from the humidity in the house is poured into the water tank. A hose branch is connected to the pump inlet from the bottom of the tank, and the pump outlet continues with a misting hose to the back of the cooler's condenser, and is connected to the drip catcher and then the misting nozzle in front of the radiator. After a short time, when some water has collected in the tank, we connect the adapter to the power supply (it is important to note that it is essential to connect the positive and negative wires to the positive and negative wires of the pump, and the float and timer must also be placed in the path of the positive wire). The timer starts counting according to the setting we specified, and after completing the cycle, it connects its switch and the pump turns on and transfers some of the water in the tank to the misting nozzle, and the water is spread as mist behind the condenser, creating humid air and reducing the temperature of the condenser. Consequently, as the temperature of the condenser decreases, the gas returned to the air conditioner compressor becomes cooler, reducing the temperature of the compressor and reducing the amperage consumed, and also the process of cooling the air inside the house is faster and better. If the tank fills up quickly and the timer fails to empty the water in the tank in time and the water level rises, the float is connected to prevent overflow and turns on the pump, which remains on until the water level drops, which is exactly what the drain does here.If there is no water in the tank, the pump will not enter the circuit due to the switch on it, and it will not work without water. Since the water collected in the tank is obtained from the distillation of air humidity and is called distilled water, and distilled water is also an insulator, there is no risk of electric shock if the area around the condenser becomes wet. Also, since the water is distilled, it does not harm the radiators and other components of the condenser. According to the following calculations, the power consumption of the device is very small and can be ignored: P = V×I = 12×2 = 24 watts 24 ÷ 1000 = 0.024 kWh 0.024 × 24 hours = 0.576 kWh 0.576 × 30 days = 17.28 In every 5 minutes (300 seconds), the pump is only active for 10 seconds, meaning the pump is only on for one-thirtieth of the time, so: 17.28 ÷ 30 = 0.576 kWh It can almost be said that the power consumption of this pump is very small and negligible. Explanation of shapes, maps and diagrams Figure 1 – Overview of the system and water flow path Figure 2 – Electrical circuit diagram Main components of the system: 1. 12V diaphragm pump 2. Timer 3. Water level float (normal open mode) 4. Power adapter 5. Distilled water collection tank 6. Misting nozzle 7. Misting hose 8. Misting dripper System connections and operation: The power adapter (4) simultaneously supplies 12V to the timer (2) and the float sensor (3). Each of these, when activated, connects the positive path and starts the pump (1). Water enters the pump from the tank (5), then passes through the hose (7), and after passing through the drip catcher (8), reaches the mist nozzle (6). Finally, the produced mist is spread behind the cooler condenser. A clear and precise statement of the advantages of the claimed invention over prior inventions. Very low power consumption (about 2 watts effective during intermittent operation), Using domestic distilled water without connection to city water, Eliminates the need for specialized repair and can be installed on all air conditioner models, Increasing cooling efficiency and improving the cooler's performance coefficient, Reducing compressor depreciation and increasing the useful life of the device, Simple design with low production cost and rapid industrialization capability Description of at least one implementation method for implementing the invention The device is installed close to the interior panel. The cooler's water outlet hose is connected to the device's tank inlet. The pump's outlet is directed through the hose, after passing through the timer and drip trap, to the mist sprayer behind the condenser. When the cooler is operating and water accumulates in the tank, the float detects the level and activates the pump. The timer controls the pump operation at specific time intervals based on the user's settings. Installing the device does not require any changes to the main circuit of the cooler and can be applied to all home split models. Explicit mention of the industrial application of the invention The present invention can be used in air conditioner manufacturing industries, cooling accessory equipment manufacturing factories, and all home, office, and commercial centers. Its main application is in hot regions of the country where air conditioners are widely used, and it can be commercialized as an auxiliary energy optimization system to save electricity.
