    摘要: The invention relates to a receiver-drier for use in an air conditioning system. This receiver-drier has (a) a lower portion defining a lower chamber in the receiver-drier; (b) an upper portion defining an upper chamber in the receiver-drier; and (c) a strainer for removing foreign particles from the refrigerant. The lower portion has an inlet for allowing the refrigerant to flow into the lower chamber and an outlet for allowing the refrigerant to flow out of the lower chamber. Each of the inlet and the outlet is formed at a bottom of the lower portion. The upper chamber is on top of the lower chamber and is charged with a desiccant for removing moisture from the refrigerant. The strainer is disposed at a position in a flow of the refrigerant from the inlet to the outlet.
