When you fry a piece of fish, the flesh is most succulent and tender within a very narrow temperature range. Because the cooking temperature of the pan is at least 200 Â°C / 392 Â°F hotter than the ideal core temperature of the fish, the edges will inevitably be far more cooked than the center when pan-fried.
Most room air conditioners operate on 115-, 125- or 220-volt circuits. ACs with cooling capacities below 15,000 BTUs usually run on standard residential (115- to 125-volt) circuits. Window ACs with cooling capacities above 15,000 BTUs usually run on 220-volt circuits.
For central air unit, the compressor is in the outside unit. For window unit, the compressor is outside the window. For the portable air conditioner, the compressor is inside the room in the cooled area. The compressor is also bigger because of the higher BTU rating cited above.
