Embodiment Construction

[0015] The term "failsafe" is defined as being able to automatically and safely compensate for failures of mechanisms or power sources.

[0016] A supercritical flat panel heat collector, also referred to as "SFPC", wherein the flat panel heat collector comprises a supercritical heat transfer fluid having at least one benefit selected from the group consisting of: low pressure loss, low heat loss, extremely Optimum heat transfer and elimination of freezing of heat transfer fluids. Effectively, if not completely, eliminating freezing design and operational considerations can lead to operational simplification and cost reduction at least -40 degrees Fahrenheit. The heat transfer fluid of the SFPC has a maximum surface tension of 20 dynes / cm, which can partially reduce the tube diameter. A reduction of at least a minimum of 50% in tube diameter which enables excellent heat transfer fluid distribution across at least more surfaces of the SFPC, and in most cases an increase in hea...

Abstract

A high efficiency flat panel collector is disclosed using an integral supercritical heat transfer, and a series of fail-safe mechanisms. Using the preferred configuration with solar concentrators and integral energy conversion devices, including the further preferred utilization of ionic liquids or ionic liquid polymers as the working fluid in the system, achieves optimal total energy efficiency. Strategic use of the flat panel collector can further yield enhanced functionality of mechanical pumps, heat pumps, and expansion energy transformation devices.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application Serial No. 60 / 596,248, filed September 11, 2005. technical field [0003] The present invention relates generally to supercritical solar collectors and supercritical heat exchangers, and more particularly to supercritical solar collectors and configurations for high efficiency energy conversion. Background technique [0004] Solar collectors are well known in the art. A solar collector is essentially a device that transmits solar energy, usually thermal energy as a means of directing photon energy to an energy conversion device, or as a means of transferring heat into a heat transfer fluid. Throughout this application, the present invention will refer to supercritical flat plate collectors, it being understood that the name flat plate stands for contiguous plates, which may be replaced by shape-modified and non-contiguous collectors without alterin...
