Abstract
The invention discloses a method for testing gravity driving two-phase fluid loops compatibility. The method can effectively simulate a decomposition process of a gravity driving two-phase fluid loop ammonia working medium under high temperature by taking nickel as a catalyst, and can determine the compatibility of the gravity driving two-phase fluid loops. According to the invention, an equivalent simulation test member is employed for simulating the decomposition process of the gravity driving two-phase fluid loop ammonia working medium on the day period, non-condensable gas amount generated by the gravity driving two-phase fluid loop ammonia working medium on the day period can be measured by directly employing a gravity heat pipe non-condensable gas test method, compatibility of the gravity driving two-phase fluid loops can be conveniently determined, and the test method is fast and convenient.
