Will air-conditioned rooms dry in summer? What about air-conditioned rooms
Drink more water. If you have dry mouth and dry tongue after staying in the air-conditioned room for a long time, it is first recommended to drink more water, which is the most direct and rapid way to alleviate the discomfort of dry mouth. Instead of waiting until you are thirsty, you should replenish water at any time, because the air-conditioned room is easy to take away the water from the human body. In addition to the performance of dry mouth and dry tongue, there may also be discomfort such as dry skin, dry lips and eyes, molting, etc, Therefore, replenishing water at any time is a very important measure

It will dry a little. During the refrigeration process, the air conditioner can remove some moisture from the air. Because the temperature of indoor air drops sharply after entering the air conditioner evaporator, its relative humidity will enter a supersaturated state. At this time, a large amount of dew will condense on the evaporator fins, which is "condensation" in refrigeration terminology. Therefore, the refrigeration process is accompanied by dehumidification. Because of the dehumidification function of the air conditioner, The indoor air humidity is much lower than the normal value, and the room becomes dry.
If the air in the room is too dry due to opening the air conditioner, this problem can be alleviated by increasing the air humidity. The humidifier is recommended as the first choice for room humidification. The humidifier can not only change the liquid water into atomization state and make the water vapor evenly distributed in the room, but also purify the air and reduce the risk of human disease. If you think the humidifier is troublesome, putting a basin of water in the room also has a certain role in alleviating dryness.
The doctor suggested that an Aroma Diffuser should be placed indoors, which can effectively and immediately solve the problem of indoor air drying, humidify the air and solve the problem of air drying. For the ultrasonic aroma diffuser, the fog is sprayed out through vibration. You can contact us to learn more about aroma diffuser
Electric regulating valve flow characteristics of the definition
Control valve, also known as control valve, controls the final control of process parameters such as medium flow, pressure, temperature and liquid level by means of power operation by accepting the control signal output from the regulating control unit in the field of industrial automation process control element. Generally by the implementing agencies and valves. According to the characteristics of travel, the control valve can be divided into straight-stroke and angular travel; according to the power of the actuator used, can be divided into pneumatic control valve, electric control valve, hydraulic control valve three; according to their function and characteristics For the linear characteristics, such as percentage characteristics and parabolic characteristics of three. Regulating valve for air, water, steam, all kinds of corrosive media, mud, oil and other media. Electric control valve is used to regulate the flow of media, pressure and liquid level. According to the PLC system control signal, to adjust the valve opening, and feedback a current value to the PLC system, PLC system will be given signal and feedback signal for comparison, when there is a deviation signal and then determine whether it is positive or negative deviation, determine the motor Forward rotation or reverse rotation, until the given signal and the feedback signal, stop the motor drive. The media flow, pressure and level are adjusted to achieve the desired preset value for the PLC system. Circulation capacity Cv value is one of the main parameters of the electric control valve, the electric control valve flow capacity is defined as: When the electric control valve is fully open, the pressure drop across the valve is 0.1MPa, the fluid density of 1g / cm3 hourly Flow through the electric control valve flow number, known as the flow capacity, also known as flow coefficient, in Cv, said t / h. The flow characteristics of the electric control valve is the relationship between the relative flow of the medium through the electric control valve and its opening under the condition that the pressure difference between the two ends of the valve is kept constant. Electric flow control valve features a linear flow characteristics, such as percentage characteristics and parabolic characteristics of three. The significance of the three kinds of fluency features are as follows: (1) Equal Percentage Characteristics (Logarithmic) The relative and relative flow rates of equal percentage characteristics do not have a linear relationship, and the change of the flow rate caused by the unit stroke change at each point of the stroke corresponds to this point Of the traffic is proportional to the percentage of traffic changes are equal. So it has the advantage of small flow, small changes in traffic, traffic flow, the flow changes, that is, in different degrees, with the same regulation accuracy. (2) Linearity (Linearity) Relativeness and linearity of linearity are linear. Changes in unit stroke caused by changes in the flow is unchanged. When the flow rate is large, the relative value of the flow rate changes little, and when the flow rate is small, the relative value of the flow rate changes greatly. (3) Parabolic characteristics The flow rate varies proportionately with the two sides of the travel, and generally has the intermediate characteristics of linear and equal percentage characteristics. From the analysis of the above three characteristics can be seen, in terms of its regulatory performance, with equal percentage characteristics for the best, stable regulation, good regulation performance. The parabolic characteristics than the linear properties of the regulatory performance is good, according to the different requirements of the occasion, select any one of the flow characteristics.
