The central air conditioning system has a main unit and a terminal system. The medium used for the indoor heat and humidity load can be divided into an all-air system, a full water system, an air-water system, and a refrigerant system. Temperature sensors are installed in the water return of the main evaporator, the water outlet of the condenser and the return water, and the temperature of the pipe network is detected in real time. The analog signal (0~10V or 4~20mA) is fed back to the inverter through the built-in PID of the inverter. After the corresponding frequency command is output, the water pump speed is automatically adjusted to adjust the heat exchange speed of each circulating water, and finally the constant temperature control in the room is realized. It should be specially stated that the temperature feedback processing function is integrated in the design of the inverter, and the system does not need to be equipped with a special control module.
Stud Triac is developed on the basis of common thyristors. It can not only replace two thyristors with reverse polarity in parallel, but also requires only one trigger circuit and is an ideal AC switch device. . Its English name TRIAC is the meaning of the triac.
