To my knowledge no transformer is air conditioned. Some Transformers have fans mounted on them, however, for uprating purposes. I don't believe this is an effective cooling mechanism for dry type transformers either (fans are usually used on oil filled transformers).
What's the maximum value power capacity of dry type
Transformer oil is a much better electrical insulator than air. So, in large transformers, oil is used to reduce the flashover distances between live internal parts, thus reducing the overall bulk of the transformer. At the same time, oil helps cool the transformer either by natural convection, or by forced circulation.'Dry transformers' are transformer that do not use oil for insulation or cooling purposes. They tend to be transformers with lower voltage and power ratings, where flashover and cooling is far less relevant.
Depends on size of transformer and type (dry,mineral oil, silicone) as well as ground slope and building construction.
Yearly maintenance should include blowing out dust and then vacuuming up the dust. While the transformer is down all the bolts and terminations should be checked for tightness. Make sure that the vents in the case are not blocked by foreign objects that happen to be in the same room as the transformer.
To wire a 15 kW dry type transformer for a 240V to 480V configuration, first ensure that the transformer is rated for this voltage conversion. Connect the primary side to the 240V supply by connecting each of the two primary terminals to the respective phases of the 240V supply. For the secondary side, connect the output terminals to the load requiring 480V, ensuring that the load is compatible with the transformer rating. Always follow local electrical codes and safety standards, and consider consulting a licensed electrician for installation.

A dry type using air to cool instead of oil.
Electric company high voltage transformers used in the utility grid are typically insulated by being immersed in a tank of oil, and cooled by natural convection (circulation) of the oil. A "dry type" transformer is not immersed in oil, and is cooled by air convection or by fans.
Under most conditions, a cloth will dry faster at normal (warmer) temperature sooner than in the relatively cooler air-conditioned room. However, if the air-conditioned room has been cooled for long enough, the excess moisture will have been removed and the humidity will be lower.

It is not a good idea to place an indoor, dry type transformer in out door. In outdoor it may subject to rain etc, for which it may not have been designed to.
Because the process of refrigerating ("conditioning") air not only reduces its temperature, but also reduces its relative humidity, so the air in the bedroom is relatively dry air, and your pipes dry out from breathing it all night.
Silica gel crystals are used to dry any air drawn into the transformer.
