What is the coil of electronic expansion valve? This problem is a concern of many netizens. At present, the coil of electronic expansion valve on the market is 5-wire. However, there may be 6-wire coil of electronic expansion valve encountered by maintenance customers. Why is that?
At present, the electronic expansion valve sold in the air conditioning and refrigeration market, in order to adapt to the interface of the electronic expansion valve driver, makes the coil of the electronic expansion valve have the difference between 5-wire and 6-wire. The 6-wire electronic expansion valve coil was used in the early air conditioning products. With the continuous improvement of the electronic expansion valve technology, the 5-wire electronic expansion valve coil is now used, that is, on the basis of the 6-wire, two common ends are synthesized into one, and the others remain unchanged.
Can sometimes buy is the electronic expansion valve does not match, then how to wire?
In fact, it's very simple. The coil of the electronic expansion valve with 6-core wire has one more common end than that of the 5-core wire. If it's an electronic expansion driver with 5-core wire, you only need to disconnect the common end of the 6-core wire. Of course, for the convenience of users, you should choose the coil of the electronic expansion valve with the same core of the driver interface wire as much as possible before purchase, so as to avoid unnecessary trouble in installation!
The coil of 6-wire electronic expansion valve is also available, but it is rarely used, because the current electronic expansion valve has been upgraded on the original basis, so the matching coil of electronic expansion valve is 5-wire instead of 6-wire. If there are customers who need 6-wire electronic expansion valve coil for maintenance, it may not be so easy to find. The best way is to replace both the electronic expansion valve and the electronic expansion valve coil at the same time, so as to ensure the normal operation of the electronic expansion valve of air conditioner.
