Abstract: The present disclosure provides an air grille assembly for use especially with air conditioning and heating ducts, having a detachable grille constructed of a relatively thick material, such as wood, synthetic wood, vinyl or the like. The grille can mount against the structure and be coupled to a housing of thinner material that can fit in a standard-sized opening, and leave enough room for a standard-sized filter commensurate with such opening. Further, the disclosure can also provide an air grille assembly having a detachable grille with an exposed exterior frame with no movable or visible hardware, and can be removed from a housing by lifting the grille frame straight up or over, angling out the bottom and then sliding in the opposite direction. The grille assembly can be coupled into a structure's opening, and can include flanges to help ensure proper mounting without the use of special tools.

Abstract: An automatic recirculation airflow damper for use in electronic enclosures utilizing multiple air moving devices to cool electronic components within the enclosure. When an air moving device is removed, the damper automatically closes an orifice associated with the absent air moving device, thus preventing the loss of cooling air from the vacated orifice and the subsequent reduction in cooling capacity. In some embodiments, the damper is attached to the enclosure with hinges. In certain embodiments, the damper is configured with elastomeric material such that the interface between the orifice and the damper offers high impedance to airflow while the damper is in a closed position. The automatic recirculation airflow damper reduces electronic thermal failures and therefore increases the reliability of a system equipped with the device.

Abstract: A hot-water supply system heats water through heat exchange between high-temperature refrigerant of a heat pump circuit and water of a water circulating circuit. The system is an instantaneous water heater unit for instantaneously heating, at a water heat exchanger, water supplied through a water supply pipe and supplying hot water to a using end unit. Therefore, a large-capacity hot-water storage tank is not needed. Sufficient heat of condensation to heat water can not be produced, because pressure conditions of the heat pump circuit is not stabilized just after the start of operation. Therefore, during a short period of rising time, hot water stored in a hot-water supply tank and water from the water heat exchanger are mixed and the mixture is supplied to keep the hot water at a preset temperature. Therefore, it is possible to use a smaller hot-water supply tank.
