Identify the failure of a fully enclosed refrigeration compressor in three minutes Judgment and common sense of fluoride deficiency in central air conditioningPrecautions for the use of central air conditioner thermostat
1. What is a thermostat
The temperature controller is an electric switch device that controls the temperature of the air-conditioned room. The central air conditioner thermostat is specially designed and developed for controlling the fan coil, which is widely used in heating, cooling, ventilation and other HVAC control. The speed of the fan can be controlled manually or automatically by adjusting the wind speed button to achieve the purpose of controlling the room temperature. There are two types of central air conditioning thermostats, one is mechanical and the other is liquid crystal. LCDs are generally used nowadays, and one of its advantages is that it is equipped with a remote control, which can realize remote remote control operation. The thermostat is used to turn on and off the air conditioner, which is mainly used to control the fan and solenoid valve. Its functions are mainly to regulate the air temperature, humidity, airflow speed, cleanliness, timing and so on.
2. Working Principle of Central Air Conditioner Thermostat
The working principle of the central air conditioning thermostat is actually not as complicated as we think. Speaking of a thermostat, it is actually an electronic switching device that can regulate the temperature of an air-conditioned room. Generally, the temperature control range of the thermostat is between 18 ° C and 28 ° C. Its working principle is actually to regulate and control by the principle of pressure, and push the contact points in the controller to work by pressure.
3. Precautions for the central air-conditioning thermostat
1. The wiring must be in accordance with the correct wiring diagram. Never let water, mud, dust and other magazines be mixed into the thermostat, otherwise the parts will be damaged.
2. The output power of the thermostat is related to the safety and stability of use. If it is not selected properly, it may cause serious consequences. The thermostat products are marked with output control voltage and current. Multiply the output control voltage and current to get the output control power. The operating power of the controlled equipment must be less than the output control power of the thermostat. Otherwise, the thermostat will be damaged, which may cause a fire!
3. It is better to have free flowing air around the place where the thermostat is installed and the temperature should be stable. Also avoid installing the thermostat in a place where there is direct sunlight. When the interior is being decorated, it is best not to install the thermostat first.
4. Some brands of thermostats support multi-voltage input central air-conditioning thermostats. It is necessary to ensure that the input voltage is consistent with the allowable input voltage. Another point to be mentioned is that some thermostats do not support the on-off of DC power, or the DC voltage that can be turned on and off is small. This should be consulted with the merchant when buying the thermostat to avoid unnecessary Trouble.
