Basic knowledge and selection method of household air coolersCompared with the air-conditioning fan on the market at present, the cooling fan is its upgrade version, not only the refrigeration effect is obvious, but also does not need to add Freon, very green environmental protection. The cold air can be divided into industrial cooling fan and household cooling fan. Household air conditioning is different from air conditioning, it is no Freon, is the refrigerant is water, is very environmentally friendly. And the household air-conditioning fan with wet curtain as evaporator is better than the air-conditioning fan in the shopping mall. The disadvantage is that it can not achieve constant temperature, can not make the whole room cooling significantly, the general power of the home air conditioner suitable for small areas of the room. But the air contains high oxygen content, won't get air conditioning disease, and save electricity and environmental protection. At present, there are many household air conditioners on the market, we may have a dazzling choice, the following with Guangdong Ruiping Hui to understand the relevant knowledge of the household air conditioner bar!What is a home cooling fan?Household air conditioners are also called household environmental protection air conditioners and evaporative cooling fans. No compressor, no freon, refrigerant is water, belongs to environmental protection and energy saving air conditioning. It works by pumping water from the tank uninterruptedly with a circulating water pump and spraying it evenly on the evaporative filter layer through a water distribution system. Outdoor hot air enters the evaporative cooling medium. In the evaporative cooling medium, in the evaporative cooling medium, in the evaporative cooling medium humid curtain (honeycomb filter layer of special material), the cooling effect is better. High-tech patented products) fully heat exchange with water, because of water evaporation and heat absorption and cooling of cool, clean air from low-noise fan pressure into the room.Characteristics of household air coolers(1) less investment and greater efficiency.2. Using environmental protection can not close doors and windows.3. It can replace indoor turbid, stuffy, and odorous air outside.(4) the power consumption is small, and the power consumption per hour is 0.5--0.8 degrees, without freon.5. The air volume of each household cooling fan is 1000 to 4000 cubic meters per litre.The cooling area of each Guangdong sharp platinum fan is 20--40 square meters.Cooling main parts (wet curtain) adopt imported parts.

Knowledge of large water tanks, air conditioning fans and air conditioning fansWhat is air conditioning fan?Air conditioning fans, household appliances, air conditioning fans combine the advantages of air conditioning and fans, such as air conditioning is blowing machine wind, and need to be in a closed environment, easy to make people feel uncomfortable. Although fans are natural wind, if the environment is very dirty, the wind will also be dirty. And most air-conditioning fans have dust removal network can filter air, if dust removal network with a layer of photocatalyst can also play a sterilization effect. The air conditioning fan only has 60-80W and fridge when starting refrigeration, so it doesn't cost electricity.Two, the advantages and disadvantages of air conditioning fansAdvantages: lower than the ordinary fan temperature about 5-6 degrees Celsius, low power consumption, moderate price, some products also have warm air and add anion function, small size, easy to move.Disadvantages: For large area refrigeration effect is not very good, there is no dehumidification function, high temperature is not easy to use, the use of air humidity is also increased.Air conditioning fans also have obvious advantages, which is why it can occupy a certain market share. Compared with ordinary fans, it can reduce temperature, low energy consumption, and some products also have the function of warm air, humidification, adding anions, which means that it can be used to cool in summer, warm in winter, dual-purpose, and can humidify the air, its function is obviously superior to ordinary fans.Three, the use of air conditioning fans1) horizontal placementGuangdong sharp platinum collector air conditioning fan should be placed horizontally, pay attention not to tilt when using, check the socket power supply and fan nameplate before using the same parameters.2) often add water.The fresh water must be poured into the air-conditioning fan before use, and the water level can be observed by the water mark to control the amount of water added. The power plug should be unplugged before adding water to prevent damage to the electrical components. The water level to be filled can be raised to near the "highest" position, not too full. In the use of refrigeration, attention should be paid to the situation of the water mark, when the water level drops close to the "lowest" position, that is, should be added water, otherwise the cooling effect will be lost.5b583c40d5bd39.jpg3) frozen ice crystalsGeneral air-conditioning fan franchise products are equipped with two ice crystals, every night, one of the refrigerator in the home refrigeration cabinet for a period of time, the next day out into the water tank, the effect is better.4) proper humidification.If you want to use refrigeration and humidification air supply, you must first add water to the water tank, start working about 1-3 minutes, the air temperature from the ambient temperature to reduce and achieve better results. Adding cold water or ice water to the conditioned area is a better cooling effect. If a certain amount of spice is added to the water, it will bring out a fragrant and cool breeze. In the hot summer, it will make people feel relaxed and comfortable. Press the refrigeration and humidification, the indicator light is on, start the humidification function, if cancel the humidification function and then press this key, the indicator light is off, the humidification function stops.5) swing air supplyGeneral Guangdong sharp platinum collector air conditioning fans have left and right swing air supply function, when the need to swing air supply, only need to press the "wind direction" selection key once, so that the "swing wind" indicator light on, that is, immediately automatic left and right air supply, air supply angle 120 degrees, if it does not need to swing air supply, again press the wind direction selection key, so that the "directional wind" indicator. Stop the swinging directional air supply when the indicator light is on. At the same time, it can also adjust the position of the upper and lower air supply, such as adjusting the direction of the long air guide by hand, so that the direction of the air supply can be all downward or upward, according to your needs to adjust to the desired position.

How about water cooled air conditioning fans?The air conditioning fan is actually an electric fan equipped with water cooling device. It does not have a compressor, does not use Freon, rely on the built-in pump to let water circulate in the machine, and the surrounding air cooling. In this way, the fan blade to send the wind has a cold feeling, the temperature of the outlet is generally lower than room temperature by 3 5 C, the industry known as physical energy storage refrigeration. Air conditioning fan energy consumption is much smaller than air conditioning, the price is only about 500-700 yuan, and it is not easy to cause "air conditioning disease", so it is quite popular with some practical families. But some experts pointed out that the air-conditioning fan is not perfect, if used improperly, may bring some "health risks".Air-conditioning fans refrigerate by water-cooling cycles, coupled with hot and humid summer air, cold air will inevitably cause condensation at outlets and other places, where bacteria are most likely to grow, and bacteria will be blown into the air with the cold wind. Therefore, for health reasons, the elderly and children with poor immunity should use air conditioning fans as little as possible.Of course, if we take into account many factors such as price and energy conservation, air conditioning fans will still occupy a certain market space. As long as we pay attention to dehumidification and cleaning, we can use it to "healthy" summer.1. Use pure water as far as possible when injecting water into the water cooling device. Pure water has high purity and less bacteria, which can reduce bacteria in the process of condensation. The water in the flume should be constantly added to keep it at a safe water level, and it should be replaced regularly.2. After a long period of operation, the air conditioning fan will be blocked by dust and dirt, which will affect the air flow and refrigeration effect of the filter screen and curtain. Therefore, it is best to wash it once every two weeks.Three, when using air conditioning fan, the distance should not be too close, should maintain air circulation and humidity balance. If necessary, consider using some dehumidifiers or dehumidification facilities.Four, in addition, when purchasing air-conditioning fans, we should pay special attention to safety. When choosing cold air conditioning fans, check the sink repeatedly to ensure that the fan is free from leakage. Air conditioning fans that have just been purchased or have been shut down for a long time must be filled with clean water before use. The water level can be observed by a water mark to control the amount of water added. In addition, remember to pull off the power plug before adding water.The principle of water cooled fanEvaporative air-conditioner (water-cooled fan) is a modern high-tech product designed by scientists in Australia, the United States, Sweden and other places for many years. It adopts the highly efficient "direct evaporative" refrigeration technology, the principle is based on the water in the evaporation process to absorb heat, that is, under the condition of constant enthalpy, absorb the sensible heat of the air, so that the humidity of the air (dry bulb temperature) is reduced. The specific process is: when fresh air passes through the core component of evaporative air conditioner, Swedish high-tech patented product CELDEK staggered laminated wet curtain, the temperature on the wet curtain equals the air wet bulb temperature, the circulating water contacts the fresh air directly, generates heat exchange and filters out the dust in the air (the dust filtration efficiency reaches above 80%). The air is cooled by approximating an isoenthalpy change, and the air is eventually cooled to a wet-bulb temperature close to that of the air.In the hot summer environment, the humidity of the dry/wet bulb of the air varies greatly, so the cooling effect is relatively high. Outdoor fresh air is filtered by evaporative air-conditioner and cooled, then it is continuously sent into the room, and the indoor turbid air with odor, dust and higher temperature is discharged out of the room, so that the indoor temperature is reduced and the oxygen content and quality of the air are relatively stable. Therefore, the evaporative air conditioner can achieve the dual effect of cooling and ventilation, and can create a fresh and comfortable living and working environment.

Is cool air fan easy to use?The advantage of air-conditioning fans over air-conditioning is that the price is low. Air-conditioning fans are naturally a good choice for people with less economic conditions. For those who have just joined the work force, every penny has to be planned, so it is necessary to buy a good air-conditioning fan in the hot summer. Today, we will show you some attentions about the air-conditioning fan.Matters needing attention in air conditioning fans1, frozen ice crystals.Generally, the Guangdong Ruiping Hui air conditioning fan is equipped with two ice crystals, which can be exchanged for ice crystals to maintain the air conditioning can be used continuously, each night can be frozen in the refrigerator, the other can be used. The effect is better and more convenient.2, add water regularly.The fresh water must be poured into the air-conditioning fan before use, and the water level can be observed by the water mark to control the amount of water added. Before adding water, the power plug should be pulled out to prevent damage to the electrical components. The water level to be filled should be raised to near the "high" position, and should not be too full. When used as refrigeration, we should pay attention to the situation of the water mark. When the water level drops to near the "low" position, we should add water, otherwise we will lose the refrigeration effect.3, horizontal placement.Air-conditioning fan should be placed horizontally, be careful not to tilt when using, check the socket power supply and fan nameplate before using the same parameters.5b583c40d5bd39.jpg4, properly humidified.If you want to use refrigeration and humidification air supply, you must first add water to the water tank, start working about 1-3 minutes, the air temperature from the ambient temperature to reduce and achieve better results. Adding cold water or ice water to the conditioned area is a better cooling effect. If a certain amount of spice is added to the water, it will bring out a fragrant and cool breeze. In the hot summer, it will make people feel relaxed and comfortable. Press the refrigeration and humidification, the indicator light is on, start the humidification function, if cancel the humidification function and then press this key, the indicator light is off, the humidification function stops.5, swing air supply.Guangdong sharp platinum collector air-conditioning fan usually has the function of swing air supply, when the need to swing air supply, just press the "wind direction" button once, "swing wind" indicator light on, immediately automatic left and right air supply, air-conditioning fan supply angle is 120 degrees, when no swing air supply is needed, then press "wind direction" again. After directional light is turned on, the directional air supply is stopped. At the same time, it can also adjust the position of the upper and lower air supply, such as adjusting the direction of the long air guide by hand, so that the direction of the air supply can be all downward or upward, according to your needs to adjust to the desired position.6. MaintenanceIf the fan is no longer in use, it should be emptied out of the water tank, and then air supply at room temperature for a period of time, this is mainly the filter screen part of the drying machine, dried and then covered with plastic bags, sealed collection.Can the air-conditioner fan be cold for one night?The answer is: "yes". The air conditioning fan is actually an ordinary fan with a power of roughly fifty or sixty watts. The electricity consumption should be between one or two degrees per day.

Is cool and warm air conditioning fan easy to use?Air-conditioning fan is a kind of household appliances between air-conditioning and fan, mainly divided into single-cooled air-conditioning fan and cold-warm air-conditioning fan, single-cooled air-conditioning fan can only refrigerate; and cold-warm air-conditioning fan can not only cool down, but also blow warm air, so the price is relatively expensive, generally about twice the single-cooled air-conditioning fan. Air conditioning fans are helpful to families with special diseases and rooms that are not allowed to operate.Working principle of air conditioning fanCold and warm air conditioning fan is a new concept of the fan, both air supply, refrigeration, heating, purification of air and humidification and other functions in one, with water as the medium, can be sent below the room temperature of cold air, but also can send out warm and humid wind. It uses ice crystals to lower the temperature of water and then to blow out the cool air. It has the functions of humidification, anion, air volume and remote control. Compared with electric fans, air conditioning fans have more fresh air, smell removal function, and power is only about 60-80W, the price is relatively low. For the majority of wage earners and urban residents, the use of cold and warm air conditioning fans can avoid the trouble of meter tripping, but also comfortable feeling.Advantages and disadvantages of air conditioning fansThe cold and warm air conditioning fan has very distinct advantages: the temperature of the cold and warm air conditioning fan is about 5-6 degrees lower than that of the ordinary fan, low power consumption, moderate price, some products also have the function of warm air and adding anions, small size, easy to move. However, the cold and warm air conditioning fan also has its drawbacks: it can not refrigerate itself, it needs to continuously inject the required temperature of water to continue to provide the required temperature of the wind, so it is inconvenient to use. For large area refrigeration effect is not very good, there is no dehumidification function, high temperature is not easy to use, the use of air humidity is also increased. It can not match the cooling effect and refrigeration speed of air-conditioning. The noise is too large to be used in hospitals, old and young rooms, etc.Why hot and cold air conditioning fans sell wellCold and warm air-conditioning fan refrigeration through physical energy storage, this refrigeration is very limited, at best than the ambient temperature is 3-5 degrees lower than the cooling capacity of air-conditioning is simply incomparable, but cold and warm air-conditioning fan is still very popular? In fact, this is mainly due to the high affinity price of the cold and warm air conditioning fan compared with the air conditioning, and the superiority of the performance of the fan, especially for the elderly and patients who can not stand the cold air conditioning, the room temperature of the cold and warm air conditioning fan is just right.In addition, power saving and energy saving is one of the strong advantages of the cold and warm air conditioning fan. At the same time, the new anion generating function, humidifying function, and ice grid additional refrigeration function of the cold and warm air conditioning fan have also increased a lot of competitiveness for the hot sale of the cold and warm air conditioning fan.

Nowadays, the haze is getting heavier and heavier. With the increase of air pollution concentration, more and more users begin to choose to put an air purifier at home to protect the health of their families. Air purifier belongs to small electrical appliances, it is also relatively simple to use, so many people think it only needs to switch on and off, do not need any maintenance.In fact, the maintenance of air purifier can ensure its longer life and enhance its purification effect. So how can air purifiers be used? Air purifier is a kind of product which can replace polluted air with fresh air and improve air cleanliness effectively. According to the different working modes, the air purifier can be divided into passive, active, active and passive mixing; according to the different pollutant removal technology, the air purifier can also be divided into mechanical filter, electrostatic electret filter, high-voltage electrostatic dust collection, anion and plasma air purifier. It can be said that there are so many kinds of air purifiers, so many technologies, can meet different levels of pollution of air purification.Air purifiers want to maximize efficiency, then the first place to place, remember not to place by the wall or home, it is best to be more than 1 meter away from the wall.Some people think that the longer the air purifier is turned on, the better the purifying effect. In fact, this is a wrong concept. Generally speaking, when the air quality is good, there is no need to turn on the air purifier, or when people are no longer in the room, the air purifying can be turned off. This is the device.Close the windows when the air pollution is serious again. When the air pollution is serious, close the doors and windows to form a closed environment in the room. This can make the air purifier more effective.Humidified air purifier use: Some users use air purifier with humidification function, it is necessary to pay attention to humidified air purifier can not be used in rainy season and humid places, otherwise it will reduce the purifying effect of air purifier.Air purifier should be replaced after a period of time, the replacement time should be determined according to the local environmental pollution and use. Regular replacement of filter screen can improve the performance of air purifier, and make it purify more thoroughly, and the effect is better.
