Abstract: The present invention relates to a seat or chair cooling apparatus. In an embodiment the seat cooling apparatus cools the back of a user without the need of forced air. The seat cooling apparatus includes an array of conduits held in place by a set of supports to form a heat exchanger. Heat from the contact surfaces is removed by free convection, an upward air movement due to density difference. When the seat cooling apparatus is in the preferred substantially vertical arrangement, the warm air exiting the conduits is replaced by cooler air entering the conduits. A seat securing attachment secures the heat exchanger components to a seat. The seat cooling apparatus shapes into the back of the user to provide comfort that is effective in cooling. The seat cooling apparatus can be light weight, portable, and occupies little space, can be quickly installed and removed, easily cleaned and is very low cost to manufacture.

Abstract: A combination water heating and space heating apparatus includes a water heating unit and a space heating unit. The water heating unit has a water storage tank, a heating device for heating water stored in the tank, and a first temperature sensor for sensing water temperature. The space heating unit includes a heat exchanger for heating air supplied to an indoor space, a blower for blowing air over the heat exchanger, and a second temperature sensor for sensing air temperature in the space. Heated water is supplied from the tank to the heat exchanger by means of a circulation pump when the second temperature sensor indicates a demand for heat in the space. The apparatus is controlled to give priority to domestic hot water use (e.g., potable water) over space heating use.

Abstract: A chimney liner adaptor is provided to allow air to flow between the outside environment and an annular space in a lined chimney flue. The adaptor may allow an air cooling system to operate but prevents undesirable elements from entering the annular space. The liner adaptor may be disposed between the chimney cap and the top walls of the chimney system and around the chimney liner. The adaptor may include perforated material, such as an expanded metal mesh, a metal screen, stamped metal screen, rugged netting, or the like. The perforated material permits gas flow, provides structural support for other elements of the adaptor, and filters out undesirable objects from entering the chimney.

The fluid is transported within the tubular members to a return manifold, wherein said fluid is recycled to the heat source.

Abstract: Disclosed are an apparatus and a method for controlling compressors of an air conditioner. The apparatus includes a temperature sensor, a comparison unit, and a controller. The temperature sensor is installed close to an outdoor unit and serves to sense an outdoor temperature. The comparison unit compares the outdoor temperature sensed by the temperature sensor to a predetermined temperature. The controller determines a heating load when the comparison unit determines that the outdoor temperature is more than the predetermined temperature, and controls the operation of the plural compressors based on the determined heating load. The apparatus determines the heating load by means of the outdoor temperature, and properly operates the plural compressors depending the determined heating load, thereby improving the heating efficiency of the air conditioner.

Abstract: The object of the present invention is to provide a compact lightweight heat pump hot-water supply system. The 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. In this system, therefore, large-capacity hot-water storage tank in conventional systems is no longer 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.

The control device is adapted for remotely switching the vent blades between an air passage position and an air blockage position. In which, at the air passage position, the vent blades are rotated to open the ventilating slot respectively for allowing the airflow passing therethrough, and at the air blockage position, the vent blades are rotated to close the ventilating slot respectively for blocking the airflow passing through.

Abstract: A clip to hold in place air conditioning vents in vehicles is an arcuate device adapted to snap onto the shaft between the end wall of the rotor and the end wall of the housing in an air conditioning vent. The clip is substantially V-shaped, having two diagonally opposed sides which are integrally connected at one end to form a closed portion and diverge outwardly at their opposing ends to form an open portion. The open portion is adapted to receive and envelop the vent shaft. The clip's curvature is adapted to allow the spaced sides to frictionally engage the end wall of the housing and the convex surface to frictionally engage the end wall of the rotor. Once mounted in the vent, the clip positively positions the rotor at a selected angle.
