| 摘要 |
The present invention includes a solar water heating system including: a wat er tank to hold water to be heated, an heat transfer fluid circuit including an heat exchanger associated with said water tank to heat water therein, a sola r collection means in communication with said heat exchanger, an inlet connection to carry heat transfer fluid from said solar collection means to said heat exchanger where said water will be heated; and an outlet connectio n to carry heat transfer fluid from said heat exchanger to said solar collecti on means where said heat transfer fluid will be heated, said heat transfer flui d circuit including a reversibly evaporable heat transfer fluid which will absorb heat from said solar collection means and which will transfer said he at to said water in said water tank by means of said heat exchanger; and an expansion means being provided in said heat transfer circuit, whereby when a portion of heat transfer fluid changes to a gaseous state in said solar collection means, heat transfer fluid in a liquid state will be forced out o f said solar collection means under pressure into said expansion means.</SDOAB > |
