    摘要: In an air conditioning system, a first expansion device and a second expansion device playing a different role from each other are controlled in a different control method suitable for each role, thereby improving the performance and stability of the system. Furthermore, the control method for the first expansion device is differentiated according to the operation state of the air conditioning system, thereby improving the stability of the system. Furthermore, the intermediate pressure can be adjusted more rapidly and precisely according to the state of the air conditioning system by differentiating the control method for the first expansion device for adjusting the intermediate pressure depending on the degree of superheat of the refrigerant, thereby improving the stability and performance of the system. Furthermore, the first expansion device is gradually opened by controlling such that a change in opening degree may change according to the opening time of the first expansion device, thereby improving the stability of the system and achieving more stable switching of the control method for the first expansion device.

    摘要: Disclosed is an apparatus and method for forming an oxidation layer on a manifold block for a fuel cell stack, which forms an oxidation layer uniformly over the entire surface of a long and complicated internal flow field of a manifold block. In particular, the apparatus for forming an oxidation layer on a manifold block for a fuel cell stack includes: an electrolyte bath which contains an electrolyte required for the formation of the oxidation layer, an electrode for supplying a required electron flow for the formation of the oxidation layer from a power supply to the manifold block immersed in the electrolyte of the electrolyte bath and to the electrolyte, and an air supply for supplying oxygen to the electrolyte. Even more particularly, the electrode connected to the electrolyte is inserted into each internal flow field of the manifold block to provide an effective electron flow therein.
