Publication number: 20100307734Abstract: Method and device for storing thermal energy in, and recapturing thermal energy from, respectively, an underground energy storage (1), having at least four holes (2), through which a heat carrier is transported and therewith heating or cooling the ground (3), respectively. The holes (2) are arranged essentially along at least two concentric circles (10, 11, 12). A control gear is arranged to control a valve system, which is arranged to direct the heat carrier to holes that are arranged along one circle and thereby heating or cooling, respectively, the ground along the circle. When the temperature of the heat carrier is higher than that of the surrounding ground (3), inner circles are heated before outer circles, and when the temperature of the heat carrier is lower than that of the surrounding ground (3), outer circles are cooled before inner circles.Type: ApplicationFiled: January 22, 2007Publication date: December 9, 2010Inventors: Thomas Wildig, Björn Giertz

Patent number: 7848900Abstract: The invention comprises a system for calculating a value for the effective thermal mass of a building. The climate control system obtains temperature measurements from at least a first location conditioned by the climate system. One or more processors receive measurements of outside temperatures from at least one source other than the control system and compare the temperature measurements from the first location with expected temperature measurements. The expected temperature measurements are based at least in part upon past temperature measurements obtained by said HVAC control system and said outside temperature measurements. The processors then calculate one or more rates of change in temperature at said first location.Type: GrantFiled: September 16, 2008Date of Patent: December 7, 2010Assignee: EcoFactor, Inc.Inventors: John Douglas Steinberg, Scott Douglas Hublou

Patent number: 7832925Abstract: Apparatus and method are provided for facilitating simulation of heated airflow exhaust of an electronics subsystem, electronics rack or row of electronics racks. The apparatus includes a thermal simulator, which includes an air-moving device and a fluid-to-air heat exchanger. The air-moving device establishes airflow from an air inlet to air outlet side of the thermal simulator tailored to correlate to heated airflow exhaust of the electronics subsystem, rack or row of racks being simulated. The fluid-to-air heat exchanger heats airflow through the thermal simulator, with temperature of airflow exhausting from the simulator being tailored to correlate to temperature of the heated airflow exhaust of the electronics subsystem, rack or row of racks being simulated. The apparatus further includes a fluid distribution apparatus, which includes a fluid distribution unit disposed separate from the fluid simulator and providing hot fluid to the fluid-to-air heat exchanger of the thermal simulator.Type: GrantFiled: December 5, 2007Date of Patent: November 16, 2010Assignee: International Business Machines CorporationInventors: Matthew R. Archibald, Richard C. Chu, Hendrik F. Hamann, Madhusudan K. Iyengar, Roger R. Schmidt
