Abstract: A hot water supply apparatus of the present invention includes: a direct water inlet pipe into which direct water is introduced; a heat exchanger for heating direct water introduced through the direct water inlet pipe with combustion heat of a burner; a hot water supply pipe for discharging the hot water heated in the heat exchanger; a bypass pipe connected between the direct water inlet pipe and the hot water supply pipe so as to mix a part of the direct water introduced through the direct water inlet pipe with the hot water discharged through the hot water supply pipe; and a pressure reducing valve provided on the bypass pipe and configured to reduce the pressure of water passing through the inside of the bypass pipe to supply the water to the hot water supply pipe when hot water is supplied.

Abstract: Disclosed is an air conditioner including a main chassis receiving various components inside, a heat exchanger installed inside the main chassis so as to exchange heat with a room air, a blow fan installed inside the main chassis so as to suck in and blow out the room air, a front panel attached to a front side of the main chassis and having an intake inlet at a front face so as to make an air flow in the heat exchanger, and an intake panel installed at the front face of the front panel to revolve to move so as to close/open the intake inlet selectively, the intake panel installed at the front face of the front panel so as to be detachable. The present invention enables to provide a compact air conditioner having an improved exterior.
