摘要： A ventilator includes an exhaust air duct for exhausting air from an interior space to an outside and a supply air duct for supplying air from the outside to the interior space, and is equipped with a heat exchanger and a defroster. The heat exchanger performs heat exchange between air passing through the exhaust air duct and air passing through the supply air duct. The defroster defrosts, when frost attaches to the heat exchanger, the heat exchanger by, after air flows into the exhaust air duct or the supply air duct, changing a state of the air.

摘要： A storage water heater is provided that allows for improved maintenance of hygiene in a lower part of a hot-water storage tank and in a passage connected to the lower part of the hot-water storage tank. A storage water heater includes a heating device, a hot-water storage tank, a first passage, and a controller. The hot-water storage tank stores hot water. The first passage is connected to a lower part of the hot-water storage tank. The controller is configured to selectively switch between a heat-up operation and a recirculation operation. In the heat-up operation, hot water heated by the heating device is delivered to an upper part of the hot-water storage tank. In the recirculation operation, hot water flowing out from the upper part of the hot-water storage tank is delivered to the lower part of the hot-water storage tank via the first passage.

摘要： In an air conditioning system, a thermal source device generates cold water from cooling water cooled by a cooling tower. A cooling water circulation passage allows circulation of the cooling water between the cooling tower and the thermal source device. A first heat exchanger exchanges heat between air and the cold water. A cold water circulation passage allows circulation of the cold water between the thermal source device and the first heat exchanger. A second heat exchanger exchanges heat between the cooling water cooled by the cooling tower and the air heat-exchanged with the cold water by the first heat exchanger. A cooling water branch passage, introduces to the second heat exchanger the cooling water introduced to the thermal source device from the cooling tower, and introduces to the cooling water circulation passage the cooling water heat-exchanged with the air by the second heat exchanger.
