Automotive air conditioning maintenance
This R1234yf Maintenance Product includes two kits. Both Maintenance Kits supply better maintenance function for R1234yf Refrigerant in automotive A/C conditioning. One is the deep governance kit the other is essential maintenance kit.
The purpose of oil in a refrigeration system is to lubricate the compressor that produces cold air. Oil reduces friction on metal parts, reducing wear on the compressor and prolongs the life of the system.
If you recharged your vehicle's air conditioning system with R1234yf Refrigerant and it still dosen't work, or if you have a newly installed A/C compressor, you may need to put the R1234yf Maintenance Product - Refrigerant Oil in it.

We know that in many situations where physical control of fluids is required, two types of valves that can adjust the opening according to the signal are often seen: one is to use 4 to 20 mA current for opening control, and the other is to use DTA and DTB. The current output type of the thermostat can achieve satisfactory results; while the second type of valve uses two output signals to control the positive and negative rotation of the valve position motor, and the motor rotates forward when the forward signal is actuated; similarly, When the reverse signal is activated, the motor is reversed; when both signals are not input, the valve position remains at a fixed opening.
The second type of valve is currently popular in the market because it can be used in more sophisticated control applications. In fact, Zhongda Dentsu has rich design experience in the temperature control technology of these two valves. According to the needs of the market, Zhongda Dentsu relies on the technical strength of the parent company Delta Electronics to quickly grasp the needs of domestic industry users. Features, the valve position temperature controller required for two signal-controlled valve position motors - DTB9696RRV. This controller combines all the functions of the highly intelligent DTB series temperature control, and specially adds the valve position control and four sets of PID parameter functions. The main functions and features are as follows:
1) The system program is specially developed for valve position applications. The parameters are easy to set and the control precision is high. It is especially suitable for the related equipments in the central air conditioning, freezer, industrial furnace and printing and dyeing industries.
2) Built-in valve position system environment PID parameter Auto Tuning function.
3) Built-in 4 sets of PID parameters, which can be set at different set temperatures or the system can switch to the most suitable PID parameters.
4) The external wiring has an interlock function, and the forward/reverse signals will not enter at the same time to avoid burning the valve position motor.
5) It has the function of valve position feedback signal, which can be set by the parameter according to the type of valve.
6) With the feedback function valve position, all system parameters can be automatically measured by Auto Tuning, without manual input, such as: motor running time, feedback signal minimum and maximum range.
7) System output/input and control methods are equivalent to DTB series high performance models.
Since entering the domestic market, Zhongda Electric has relied on the strong technical support of Delta Electronics, and has made great progress in the fields of inverters, PLCs, thermostats and servo motors, and has shown strong development momentum. . Due to the high technical content of the products, it is comparable to well-known brands in Europe and America, and more affordable in terms of price. Therefore, it has gradually established a broad user base in the fields of papermaking, textile, plastic machinery and construction. The DTB9696RRV valve position controller introduced this time is in line with the characteristics of Delta's DTB series thermostats supporting simulation input and output, and built-in ASCII/RTU communication format, which fully reflects the mid-to-high-end market positioning of Delta's valve position controller. It demonstrates the technical strength of Delta Electronics in the field of temperature controllers. In the highly competitive electromechanical market, in addition to the technical content of the products, the performance-price ratio is an important factor in determining the user's choice of products. Delta's valve position controller, which combines many advantages, will undoubtedly not neglect the market development in the next two years. The impact.
Zhongda Instrument Tim Ding DTB valve position controller debut
