  • Patent number: 10006678
    Abstract: An air-conditioning apparatus includes a intermediate heat exchangers operating as a condenser or an evaporator and allows each intermediate heat exchanger to exchange heat between a refrigerant heated or cooled in a refrigeration cycle on a heat source side and a heat transfer medium flowing through a heat transfer medium circuit on a use side such that heat energy produced on the heat source side is transmitted to use side heat exchangers. A controller calculates the heat transfer medium temperature difference between a heat transfer medium inlet and outlet temperatures. When a detected value of a heat transfer medium temperature detecting device deviates from a predetermined range, the controller changes the target heat transfer medium temperature difference and controls a heat transfer medium flow control device, such that the heat transfer medium temperature difference reaches the changed target heat transfer medium temperature difference.

  • Patent number: 9999163
    Abstract: Embodiments of the invention provide high-efficiency cooling in a data center in response to a cooling and/or humidity demand using a system having multiple cooling loops to allow for a higher chilled liquid temperature of a first chilled liquid loop, while maintaining data center room temperature and humidity control. Specifically, the system includes a plurality of integrated cooling systems each comprising one or more specifically sized chillers and a liquid loop to address the cooling demand. A free cooling heat exchanger is coupled to the first liquid loop for use when a wet-bulb temperature surrounding the data center is at or below a free cooling set point of the first chilled liquid loop. The system isolates humidity control components to a second chilled liquid loop, and enables greater control of the first chilled liquid loop of the data center to meet specific IT loads.

  • Patent number: 9989322
    Abstract: A heat recovery device such as an EGHR device includes a bypass valve, a gas/liquid heat exchanger and a flow duct. The flow duct has an open top and an open bottom. A top surface of the duct seals to a surface surrounding an opening of a gas flow conduit, such as an exhaust pipe. A duct wall extends from the top surface to the bottom surface, to which the heat exchanger is secured. The flow duct provides a passage through gas flows between the gas flow conduit and the heat exchanger. The bypass valve is mounted in the flow duct and is movable between a bypass position and a heat exchange position. The bypass valve may be mounted adjacent to the top or bottom of the duct, and may be a butterfly-type valve, a one-sided flap valve, or a pair of one-sided flap valves.

  • Patent number: 9982955
    Abstract: A method for operating a heat exchanger, through which a heat transfer medium flows on a primary side, entering the heat exchanger with a first temperature and exiting the heat exchanger with a second temperature. The heat transfer medium emits on a secondary side a heat flow to a secondary medium flowing through the heat exchanger in the case of heating or, in the case of cooling, absorbs a heat flow from the secondary medium which enters the heat exchanger with a third temperature and exits the heat exchanger again with a fourth temperature. The heat exchanger is capable of transferring a maximum heat flow. At least three of the four temperatures are measured and the respective saturation level of the heat exchanger is determined from these measured temperatures and is used for controlling the operation of the heat exchanger.

  • Patent number: 9982931
    Abstract: A control system is used for controlling the equalization of pressure between absorbing and desorbing reactors. In a first reaction cycle in a desorbing reactor a gaseous reactant is desorbed from a solid sorbent and concurrently in an absorbing reactor the gaseous reactant is absorbed on a solid sorbent. In a second reaction cycle, absorption and desorption are reversed in the reactors and at least a portion of the gaseous reactant desorbed from in the desorbing reactor is transferred to the absorbing reactor in an equalization process under computer control. The computer control may detect the demand on the system and adjust the amount of time for the equalization process to increase the efficiency of the system.
