What is a cooler inverter

The frequency conversion speed control system used in the air cooler is generally composed of sensors, transmitters, regulators, controllers, inverters, motors and controlled equipment. Ningbo air cooler, Ningbo air cooler

    The sensor is used to sense the controlled parameter in the controlled device. It can be flow, pressure, temperature, humidity, gas content, etc. Generally, the controlled parameter is converted into an electrical signal by the sensor.

    The function of the transmitter is to amplify and shape the electrical signal obtained by the sensor, and then uniformly adjust it to a regular voltage, such as 0V ~ 5V or current signal 4mA ~ 20mA as the input of the regulator.

    Regulators or controllers, they are actually a micro-control system composed of a single-chip microcomputer. It has functions of calculation, judgment and logic analysis. It has digital and analog input terminals, digital and analog output terminals, which can implement control laws such as PID or fuzzy control under the control of software. It can also use digital output ports to direct the switching between frequency modulation and power frequency of several motors, Various operations such as turning on or off related parts of the controlled equipment.

    The inverter is a kind of control equipment that uses the intelligent control technology of electronic devices to change the AC voltage with a fixed frequency and frequency into an AC voltage with a variable frequency and frequency. The variable frequency and voltage AC power used by the inverter to drive the motor can reach the speed regulation of the motor. Inverter is generally composed of power supply part, output part, control part, protection part, display part and given part. The capacity ranges from tens of watts to hundreds of kilowatts, and there are both three-phase and single-phase. For more than ten years, the reliability of inverters has become stronger and stronger, the prices are getting lower and lower, and the fields of application have become wider and wider.

In this case, the sensors, transmitters, and regulators are held by human features and brains. After the deviation of the controlled parameters of the system is observed or felt, the manual setting method is used to adjust the given value of the inverter to change the speed of the motor, thereby achieving the purpose of controlling the controlled parameters.

What is the process of defrosting the air cooler

The cold air blower can be forced to supply air and improve heat exchange efficiency; it has a water receiving tray, convenient defrosting, and can adapt to various working conditions; relatively cheap, low initial investment; it has become the most common evaporator for refrigeration system applications. Let's take a look at the defrosting process of the air cooler.

   Defrosting the air cooler can be done by electric defrosting or defrosting. After the defrost is completed, the dripping time can be increased. After the dripping is completed, the motor of the air cooler can be started.

   Efficient chiller requires a very good heat transfer coefficient, has a relatively high cooling effect in the same cooling area, and the air flow resistance of the device is small, which can greatly increase the evaporation temperature of the device and reduce the power consumption of the chiller In addition, it is necessary to calculate the fan air volume and defrosting component structure required by the equipment to reduce the power consumption of the chiller during the defrosting process.

   According to different working conditions and equipment capacity, ensure that the equipment can achieve uniform liquid supply distribution during work; according to the cold storage area, installation environment and objects that need to be cooled, design different fin structures to improve the heat transfer coefficient; The pipe technology is improved to reduce the direct contact surface between the pipe and the fins, and to enhance the heat transfer coefficient of the finned tubes. When the air cooler performs defrosting, a large energy consumption will occur, and the heating elements can be optimally replaced and reasonably distributed. The security position of the components in the heat exchanger reduces the energy loss of the defrost.

Mobile cooler is environmentally friendly, convenient and energy saving

No matter whether the mobile cooler is 30 degrees, 40 degrees, 50 degrees, dry, odor, or sultry, whether indoors or outdoors, regardless of the large workshop or small room, the use of mobile coolers can achieve cool, fresh, comfortable and convenient results.

    Mobile air-conditioners (environment-friendly air conditioners) are shipped from the factory and can be used without opening the package. There is no need for time-consuming and labor-intensive installation, and there is no danger of hanging outside the wall. application. Widely used in factory workshops, Internet cafes, cafeteria restaurants, hotel kitchens, employee dormitories, outdoor work, casual dining, offices, facades, warehouses and other places that require cooling and ventilation.

    It is especially suitable for places that require mobile use, such as fixed station cooling, mobile work station cooling, equipment maintenance mobile cooling, storage and handling cooling, and outdoor temporary work cooling. It is the best substitute for fans.

Cooling principle of mobile cooler

    The cooling fan circulating water pump continuously sends water to the wet curtain. After the wet curtain is completely soaked, a water film is formed on the surface. After the fan is turned on, dry and hot air is drawn into the wet curtain, forcing the water film water on the wet curtain to quickly evaporate from liquid. It is in a gaseous state, absorbing the heat in the hot air, causing the temperature of the airflow to drop rapidly to form a cold airflow, which is then sent out from the air outlet. During this process, the air and the water film of the wet curtain are in full contact, and dust, smoke, dust, etc. are removed, and the air Harmful gases such as SO2, NO2, NH3, etc. dissolve in water by chemical reaction with water, thereby purifying the air, and the negative oxygen ions generated during water evaporation also increase the oxygen content in the air. The mobile cooler uses the principle of water evaporation and heat absorption to reduce the temperature, so the drier the use environment, the higher the temperature, the more obvious the cooling effect.
