摘要： The invention concerns a method for detecting changes in a first flow of a heating or cooling medium in a refrigeration system whereby the first flow is conveyed through a heat exchanger wherein occurs heat transfer from the first flow to a second flow of a heating or cooling medium. The earliest possible detection of the changes is desired. For this it is provided that for the supervision of the first media flow moving through the heat exchanger a change in the enthalpy of the second media stream or a value derived therefrom is determined.

摘要： A method of constant airflow control for a ventilation system is disclosed. The method includes various controls to accomplish a substantially constant airflow rate over a significant change of the static pressure in a ventilation duct. One control is a constant I·RPM control, which is primarily used in a low static pressure range. Another control is a constant RPM control, which is primarily used in a high static pressure range. These controls requires neither a static pressure sensor nor an airflow rate sensor to accomplish substantially constant airflow rate while static pressure changes. This is because these controls use only intrinsic control variables which are electric current and rotational speed of the motor. Also, the method improves the accuracy of the control by correcting certain deviations that are caused by the motor's current-RPM characteristics. To compensate the deviation, the method adopts a test operation in a minimum static pressure condition. Also disclosed is an apparatus for conducting these control methods.

摘要： A plant for tempering a building, including an energy storage unit formed by ground heat exchangers coupled in parallel and each including a heat insulated leg and a non-insulated leg in thermal contact with surrounding soil. The heat exchangers are included in a circulating circuit for a circulation fluid which includes a circulation pump and room temperature keeping devices. The energy storage unit has a continuously varying temperature in a depth direction from a cold end to a warm end. The flow direction in the ground heat exchangers is controlled by a reversing valve such that for a warm keeping function, circulation fluid is received from the warm end and for a cool keeping function, circulation fluid is received from the cold end. The circulation pump is controlled such that the circulation flow brings about a temperature difference between the inlet and outlet of the ground heat exchangers that is constant with a value that can be calculated with the aid of the properties of the ground and the actual components.

摘要： A cooling system is configured to supply individually metered amounts of cooling fluid to heat generating components, e.g., processors, micro-controllers, high speed video cards, disk drives, semi-conductor devices, and the like, of an electronic system. The cooling system includes at least one variable speed fan, e.g., blower, configured to supply fluid through a centralized plenum and thereafter through a plurality of nozzles to the components of the electronic system. Each of the nozzles contains a valve to control the amount of fluid flow through the each of the nozzles. A controller is provided to control the operation of the variable speed fan and the operation of each of the valves is also controlled by a controller. By substantially controlling the amount of cooling fluid supplied to each of the components based upon the amount of heat generated by each component, the cooling system of the present invention may operate in a more efficient manner, thereby requiring substantially less energy than conventional cooling systems.

摘要： Method and apparatus for testing the operation of an alarm for a ventilated enclosure, such as a fume hood or bio-safety cabinet. Flow of gas being exhausted from the enclosure may be adjusted to a known value below or above a threshold value at which the alarm provides an indication that flow is unacceptably low or high. Adjustment of flow to the known value may be performed without requiring a manual measurement of flow, e.g., by performing a traverse in a duct leading from the enclosure.

摘要： A system for optimizing the flow of air through a fume hood by dynamically controlling the air flow to provide a stable vortex in the vortex chamber of the hood, the optimum condition for minimizing backflow of fume-laden air through the hood doorway. A highly-sensitive pressure sensor disposed at a critical location in the vortex chamber sidewall senses minute variations in vortex pressure indicative of turbulence and sends signals via a transducer to an analog controller which uses proportional integral and adaptive gain algorithms to formulate output signals to an actuator which adjusts dampers in the hood to change the airflow into the vortex. The system operates in feedback mode and seeks a minimum in the amplitude of the sidewall pressure variations, indicating that turbulence has been eliminated and that a stable vortex exists. The pressure sensor signals can also be directed to an alarm to signal an off-standard and potentially dangerous condition.
