Abstract
Official abstract text for this publication.
A system comprising a first plurality of microchannels, a second plurality of microchannels in thermal communication with the first plurality of microchannels such that the first plurality of microchannels and second plurality of microchannels form a heat exchanger, and a phase change composite in thermal communication with the heat exchanger and methods of operating are disclosed herein.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: directing a first plurality of tubes through a phase change composite, directing a second plurality of tubes through the phase change composite, thermally coupling the first plurality of tubes and the second plurality of tubes, exchanging heat between the first plurality of tubes, the second plurality of tubes, and the phase change composite, storing thermal energy in the phase change composite which discharged and charged throughout the day, wherein: discharging the phase change composite occurs by removing heat from the phase change composite and depositing the removed heat in the first plurality of tubes or the second plurality of tubes, charging the phase change composite occurs by depositing heat in phase change composite from the first plurality of tubes or the second plurality of tubes, and the charging of the phase change composite and the discharging of the phase change composite are controlled by a control cycle, the control cycle comprising: monitoring the current state of charge of the phase change composite, establishing a target state of charge of the phase change composite to be reached by a time period, comparing the current state of charge of the phase change composite to the target state of charge of the phase change composite, and operating a compressor connected to the second plurality of tubes to activate the second plurality of tubes to achieve the target state of charge of the phase change composite. 2. The method of claim 1 , wherein the phase change composite changes phase during the control cycle. 3. The method of claim 1 , wherein the compressor is operated such that the flow rate of the second plurality of tubes is significantly decreased. 4. The method of claim 1 , wherein the compressor comprises a variable compressor operated at a reduced speed.
