A method and system for designing and controlling a hydronic apparatus. In one aspect of the invention, the system includes a computing device having a first receiver that receives input data, in which the input data includes environmental data and hydronic apparatus data. The computing device also includes a first processor that communicates with the first receiver. The first processor processes the received input data into configuration data that includes a hydronic apparatus layout. The hydronic apparatus layout indicates a plurality of hydronic components and fluid connections between the hydronic components. The computing device also includes a transmitter that transmits the configuration data. The system also includes a controller that has a stored set of rules and a second receiver that receives the configuration data. The controller includes a second processor that processes the received configuration data to correlate the configuration data with the default rules and select a corresponding subset of the set of default rules.

A solar water heating and cooling system including a solar energy collection assembly having a heat absorbing element, a heat exchanger and a shield. The system also includes a cooling assembly, the cooling assembly is integral with the shield. The system has a check valve in fluid communication with the solar collection assembly and the cooling assembly, and a fluid pump in fluid communication with the solar energy collection assembly. A working fluid is disposed within the solar energy collection assembly, the cooling assembly, the check valve and the fluid pump. A cooling loop is defined by the solar energy collection assembly, the cooling assembly and the check valve. When the fluid pump is off, the working fluid circulates through the cooling loop, but when the fluid pump is on, the working fluid circulates through a heating loop that is defined by the solar energy collection assembly and the fluid pump.

摘要:
A primary fluid flow loop and a secondary fluid flow loop fluidly coupled to the primary fluid flow loop. The secondary fluid flow loop exchanges heat with at least one of a heat source and a heat load. The secondary fluid flow loop includes an inlet and an outlet fluidly coupling the primary fluid flow loop to the secondary fluid flow loop. A fluid flow meter coupled to the primary fluid flow loop. A first temperature sensor coupled to the primary fluid flow loop, the first temperature sensor measures the temperature of a fluid flowing in the primary fluid flow loop upstream of the inlet of the secondary fluid flow loop. A second temperature sensor coupled to the primary fluid flow loop, the second temperature sensor measures the temperature of the fluid flowing in the primary fluid flow loop downstream of the outlet of the secondary fluid flow loop.
摘要:
The present invention advantageously provides a method and system for cryogenically ablating large areas of tissue within the left atrium. In an exemplary embodiment a cryotherapy device includes a catheter body having a substantially fixed diameter, a proximal end and a distal end; a first lumen for permitting passage of a cooling fluid from the proximal end to the distal end; a second lumen permitting return of the cooling fluid from the distal end to the proximal end; and an ablation element expandable from a first diameter that is substantially the same as the diameter of the catheter body to a second diameter that is at least twice the diameter of the catheter body, the ablation element having a surface portion that conforms to the uneven surface topography of the cardiac tissue. The ablation element can include one or more balloon and/or a flexible element that is deformed by moving the distal end of the catheter toward the proximal end of the catheter. The surface of the balloon can further be shaped by regulation of pressure within the one or more balloons. In an exemplary method a tissue ablation device is provided and tissue in the antrum of the left atrium is ablated with the device. In an exemplary method, only tissue in the antrum is ablated, and the ablation is created by freezing tissue.
