Abstract
An educational device for use in instruction concerning solar heat utilization comprises a solar energy collector in which liquid is heated by solar energy indirectly through a heat-exchanger, a liquid storage tank, a pump and associated pipe system to circulate liquid between the collector and the storage tank, a valved by-pass line to permit recycle of liquid from and to the storage tank external of said collector and an instrument panel to display temperature of said heat exchanger, temperature of liquid contained within said collector, temperature of liquid contained in said storage tank and pressure of liquid flowing in said pipe system.
Claims10
An educational device for use in instruction concerning solar heat utilization which comprises:
- A. solar energy collector means comprising a chamber portion to contain liquid to be heated by solar energy absorbed by said collector means, a liquid flow inlet to said chamber portion, a liquid flow outlet from said chamber portion, and heat-exchanger means to assist in transfer of heat absorbed by said collector means to said liquid,
- B. a liquid storage tank separate from said collector means having a fluid flow inlet and a fluid flow outlet,
- C. first conduit means connecting said collector means outlet to said storage tank inlet for circulating liquid from the collector means to the storage tank,
- D. second conduit means connecting said storage tank outlet to said collector means inlet for recycling liquid from the storage tank to the collector means,
- E. pump means to produce liquid flow through said first and second conduit means,
- F. a by-pass line connecting said first conduit means to said second conduit means of liquid flow therethrough external of said collector means,
- G. a control valve in said by-pass line to regulate the quantity of liquid that flows therethrough, and
- H. an instrument panel comprising measurement display means to indicate:
- a. temperature of said heat-exchanger means,
- temperature of liquid contained within said collector means,
- c. temperature of liquid contained in said storage tank, and
- d. pressure of liquid flowing in said second conduit means.
