An indoor unit comprises a condenser, a heat preservation layer being provided on at least one of a condensing surface, a non-condensing surface, and a portion between the condensing surface and the non-condensing surface, of the condenser. During use of the indoor unit, because the heat preservation layer is disposed, when cold air is normally discharged, the temperature of the heat preservation layer does not change a lot due to the cold air; because the temperature needs to pass through the heat preservation layer to be transmitted to the side of the non-condensing surface, the temperature of the side of the non-condensing surface does not reduce to be lower than a hot flow dew point due to the cold air, thereby preventing confluence of a clod flow and a hot flow in the indoor unit, and effectively reducing the probability of condensation in the indoor unit. Also disclosed is an air-conditioning unit comprising the indoor unit.
