Sun heating equipment.

摘要

The outlet of the collectors 1 is connected to the inlet thereof by means of a line 12 in which are mounted the primary part of a heat exchanger condenser 2, a vacuum pump 3, a venting cylinder 4, and a flow-control device 10. A distributing device 14 feeds water with a pressure drop and a small flow rate from the line 12 into each collector 1. The flow rate is such that water in liquid form does not fill completely the collectors 1 and vaporizes at least for the most part before leaving the collectors 1. The heat exchanger 2 comprises a secondary part which is part of a hot water line 15 which runs in closed circuit and wherein are mounted a circulating pump 7 and a storage tank 8.
