ActiveUS20090171512A1Reduce energy consumptionImprove energy efficiencySampled-variable control systemsMechanical apparatusCooling towerControl system
A cooling system for providing conditioned air to a facility includes a chiller or other cooling subsystem, a cooling tower subsystem and one or more air handling units or process cooling units. The cooling subsystem may advantageously include one or more chillers (e.g., variable speed chillers, constant speed chillers, absorption chillers, etc.) and chilled fluid pumps. The cooling tower subsystem includes one or more cooling tower units and condenser fluid pumps. In some implementations, the air handling unit has a cooling coil and a variable volume fan. In some implementations, direct expansion (DX) cooling systems comprise compressors, evaporators and air-cooled, water-cooled or evaporatively-cooled condensing systems. Such systems can be controlled to reduce energy waste, improve occupant comfort and / or improve the thermal characteristics of the process cooling unit. The cooling system further comprises a control system which is configured to evaluate a cooling load value at the air handling unit and use the cooling load value to calculate at least one operational setpoint. The operational setpoint may advantageously be selected to improve the energy efficiency of the overall cooling system.

ActiveCN101876299AReduce dosageReduce procurement costsSteam generation heating methodsFrom solar energyThermal energyCounter flow
The invention relates to a method and a system for combining solar energy thermal power generation with biomass power generation. When the method is used for generating electricity in the daytime (a fine day), one path of heat transfer oil heated in a heat collection field passes through a heat exchanger to ensure that counter-flow water is heated up into superheated steam at the temperature of between 360 and 380 DEG C; and the other path of the heat transfer oil heated in the heat collection field passes through the heat exchanger to heat up a fused salt so as to perform energy storage. The water heated in a water cooled wall of a biomass boiler is changed into steam which enters a steam header and a steam-water separator, then is heated to the temperature of between 535 and 545 DDEG C after being sent into a super-heater of the boiler together with the steam at the temperature of between 360 and 380 DEG C, and then is supplied to a steam turbine to drive a generator to finish the power generation process. During receiving electric valley adjustment, the biomass boiler maintains the minimum stable combustion state. The self power generation of the method and the system can be used for supplying electricity to an electric heater in a fused salt heat storage system to heat the fused salt and perform secondary energy storage for a fused salt heat tank. During the night, or when a solar energy condition is not good, the heat energy stored in the fused salt is released by the heat exchanger to generate electricity.
