Do the commonly used thermal expansion valves of chillers need to be installed separately?

First of all, thermal expansion valves, generally speaking, do not need to be installed separately.

Although the thermal expansion valve is a relatively simple agregat component to install, it does not need to be installed separately. It is generally installed in the chiller host. Moreover, most of the time, it includes the various chillers. The setting parameters are adjusted when leaving the factory, and the customer does not need to perform any installation operations at all.

Secondly, how to install it?

Since the customer does not need to install it by himself, there is no need to know the installation method, and it is not recommended that the customer disassemble and repair the chiller system privately. During the warranty period, the chiller manufacturer should let the chiller manufacturer do the warranty.

The use characteristics and advantages and disadvantages of thermal expansion valve: Thermal expansion valve is a common throttling and pressure reducing device, which is widely used in various industrial chiller systems. Therefore, its characteristics and advantages are that it is widely used and stable The performance is naturally very high, and the applicability is also very strong. Almost all refrigeration systems can be applied.

Compared with the capillary tube, the thermal expansion valve needs to be more precise and more replaceable. Compared with replacing the capillary tube, the expansion valve is easier to replace, and the thermal expansion valve as a whole will not be completely damaged. It’s just that the temperature sensing device and the ejector rod are easily damaged. The installation of the thermal expansion valve is integrated with the entire chiller system. In normal use, almost no warranty is required within 3-5 years!
