  • How to use Samsung air conditioner remote control
    Samsung is a big brand with a good reputation. Its products include Samsung TVs, Samsung mobile phones, Samsung computers and so on. Samsung air conditioners are also one of them. People who have used Samsung air conditioners may know about Samsung air conditioners, but people who have not used Samsung air conditioners may not know so well. So I hope that you can learn more about Samsung air conditioners by sharing today . The use of Samsung air conditioners is inseparable from the remote control, so today the Samsung Air Conditioning Maintenance Department will share with you how to use the Samsung air conditioner remote control. Let ’s take a look. 1. Press and hold the "Timer" button with your finger, the digital display ...
  • Common daily failures of Samsung air conditioners
    Common failure phenomena (1), leakage: Refers to the leakage of refrigerant; electrical leakage caused by electrical (circuit, body) insulation damage. (2) Blocking: refers to the dirty and ice blocking of the refrigeration system; the air filter is blocked; the air inlet and air outlet are blocked by obstacles. (3) Break: refers to the disconnection of the electrical circuit; the fuse is blown; the contacts of the overload protector are disconnected due to overheating or excessive current; the contacts of the pressure relay are disconnected due to abnormal pressure in the refrigeration system. (4) Burn: Refers to the winding of the compressor motor, the winding of the fan motor, the solenoid valve coil, ...
  • How much is the air conditioner suitable for?
    Summer: Considering energy saving of 26-28 degrees Celsius, the most suitable air conditioner temperature is 24 ° C -27 ° C. So how many air conditioners should be turned on, and what is the most suitable air conditioner temperature? The most suitable air conditioner temperature is 24 ° C to 27 ° C, the minimum should not be lower than 22 ° C, and the indoor temperature difference should not be greater than 5 ° C. The air conditioner should not be lower than 24 ° C. If the air conditioner is too large and the indoor temperature is too low, it is prone to "air conditioning diseases", such as colds, cough, fever, and lack of energy. Winter: 15-18 degrees Celsius In winter indoor environment, if the indoor temperature is controlled ...
  • Explain the seven problems of air conditioning heating
    How to prevent colds has become a key issue during the cold winter. However, we often turn on the air conditioner in the summer, and many people also know that in addition to refrigeration, there is also a heating function. There are always questions about heating. I. Why the colder the weather, the worse the heating effect? Mainly because the colder the weather, the lower the outdoor temperature, the more difficult it is to absorb air from the outdoor air environment, resulting in relatively poor heating effect. Second, why is it better to use other equipment to heat below -5 degrees? When the air conditioner is heated in winter, the air conditioner absorbs outdoor air through an outdoor heat exchanger ...
  • Home air conditioner frequency difference and fixed frequency difference?
    1. The inverter air-conditioner mainframe automatically and continuously variable speed can automatically provide the required cooling capacity (heat) according to the room conditions; when the indoor temperature reaches the required value, the empty mainframe can accurately maintain this temperature and run at a constant speed, "non-stop operation" To ensure the stability of the ambient temperature. 2. The biggest difference in design is that this product uses different principles on the compressor. The compressor of the inverter product can be moderately adjusted for long-term operation. If the room does not need a lot of hot and cold, intelligent constant temperature control, the air conditioner will run at low frequency, and the fixed frequency products need to be artificial. In the case of air conditioning, adjust the hot and cold switch ...
  • Air conditioner heating and cooling that cost electricity
    Today, many people know about air conditioning, and even use it every day. Not only does air conditioning have a good cooling effect, but some people use air conditioning for heating in winter. Steam your own cold room. Of course, because the air conditioner itself has a better dehumidification function, it can remove moisture for people in the spring. People always think about cooling or heating when using, which one is more energy efficient. So in the end, air conditioning and cooling costs or heating costs? Today, let's take a look at which air conditioning heating and cooling costs are higher. Which one is more efficient for air conditioning heating and cooling? When heating, it is more energy efficient. ...
  • Common reasons for air conditioning not heating
    Common reasons for air-conditioning not heating 1. Too much dust accumulation; Generally speaking, the cooling effect of air conditioners is not good, partly because of excessive dust accumulation for the air filter, and the vents of the internal and external machines are blocked by foreign objects. Because the role of the air conditioning filter is to absorb the dust in the air, if too much dust is accumulated and not cleaned in time, it will block the air circulation, resulting in a reduction in the amount of air out of the air outlet. , Resulting in insufficient heating. [Solution] Too much dust on the air conditioner This is not a malfunction, it belongs to the maintenance problem of the air conditioner, you only need to take off the air regularly ...
  • High-capacity liquid distribution tank and its volume estimation
    The building's air-conditioning chilled water system and cooling water system are cleaned separately. Cooling water system cleaning can directly use the pool at the bottom of the cooling tower as a liquid distribution tank, while in the case of chilled water systems, a liquid distribution tank must be installed. Considering transportation and pipeline connection, it is more convenient to install the liquid distribution tank near the pump in the equipment room. The capacity of the liquid distribution tank should be equivalent to the storage capacity of the cooling water. Otherwise, once the pump is stopped, the circulating cleaning liquid of the entire building will almost completely return to the liquid distribution tank, causing overflow. The volume of the high-capacity distribution tank can be estimated from the central air-conditioning design drawings. Take Fuzhou Donghu Hotel as an example, the central air-conditioning equipment has Japanese F ...
  • Feasibility of non-stop cleaning of air conditioners in summer
    Many hotels and restaurants have suggested that chemical cleaning of air-conditioning systems is often in the middle of summer. At this time, it is the time when the air-conditioning is most needed to be turned on. When the air-conditioning is shut down for one day, passengers have opinions. If the shutdown and cleaning is bound to affect the hotel's business, causing Economic loss. As far as we wish, the chemical cleaning of the central air-conditioning of the hotel should try to choose the season when the air-conditioning is disabled, such as winter. However, according to the cleaning tasks we received, most users requested cleaning in the hot summer. There are two reasons: firstly, the shutdown in winter, the user is not as concerned about the maintenance and cleaning of air conditioners as in summer; secondly, when summer comes, air conditioning ...
  • Scale type of each part of central air-conditioning equipment and cleaning method thereof
    In order to achieve water-saving, energy-saving, and improve the cooling effect of air-conditioning equipment, it is necessary to thoroughly clean the three parts of the central air-conditioning equipment's cooling water system, chilled water system, and fin surface. Because the environment and conditions of each part are very different, the type of dirt and the degree of rust are also very different. For cooling water systems, the problem is scaling, which is the growth of a layer of insoluble salts or oxide crystals attached to the heat transfer surface. Most of it is caused by the increase of the deep cooling multiple of the circulating cooling water and the rise of the heat exchange water temperature of the condenser, which affects the solubility of salts in water. ...
