Abstract:
1. An active thermal insulation method comprising; a. providing a closed circuit of cooling fluid such as a CFC mixture; b. controlling the flow rate of said cooling-fluid through said closed-circuit; c. providing means, such as a heat exchanger, of removing the heat from said cooling-fluid; d. monitoring the temperature of said cooling-fluid by means of a temperature gauge; e. monitoring the temperature of said contained body; f. monitoring the temperature of said external body; g. monitoring the flow rate of said cooling-fluid using a flow meter; h. providing a control means, such as inter alia a digital computer, which receives data from said flow meters and temperature gauges, processes the data and sends control signals to the pump or the heat exchanger; wherein said temperature controlling provides an actively thermally insulated virtual envelope of constant temperature between said contained body and external body.
