Abstract
In an air conditioning system for circulating a fluid which can change a phase between a gas phase and a liquid phase by a difference of a specific gravity between the gas phase and the liquid phase between an heat source side machine and a plurality of user side machines more than half of which are disposed below the heat source side machine, so that each of the user side machines performs a cooling operation, each of the user side machines is provided with a heat exchanger, a flow control valve for controlling a volume of said fluid supplied to the heat exchanger, a blow means for supplying an air-conditioned air to a room through the heat exchanger, a physical value detecting means for detecting a physical value relating to an air conditioning load such as a temperature and a signal controlling means for the operating and detecting portions, and wherein the heat source side machine is provided with a control means for communicating with said signal controlling means and outputting a control signal to said flow control valve of the user side machine. Accordingly, even in the case that the cooling load is the same, the opening ratio of the flow control valve of the user side machi…
