hello,every one.
Te=-25c or Te=-20c or Te=-15c,what about to choose the expansion valves ??

With your expert knowledge as a qualified "jjhhjj" I would have thought that this level of question would have been easily solved by yourself.

everybody !
my meaning:select the expansion valves in the air -condition (te=2c)? or select the expansion valves in the low- condition (Te=-25c or Te=-20c or Te=-15c)? if Te=-25c select the expansion valves in the air -condition (te=2c),ok????

What duty, what operating range (A/C or medium or low temperature) what refrigerant, what condening pressure, what evaporating pressure.

In selecting expansion valve, it is dependent on the pressure drop of your system; evaporating capacity (refrigerating effect) and evaporating temperature.

In catalogue, there’s always an option of the range of temperature and that temperature refers to your evaporating temperature of your unit. You can refer danfoss catalogue to know more about selecting expansion valves.
