  • Receiver drier and economizer integration for vapor injection system
    Patent number: 12253287
    Abstract: An integrated receiver drier and economizer (RDE) includes a tank having a hollow interior receiving a first flow of a refrigerant therein, the first flow of the refrigerant including a liquid phase of the refrigerant accumulating within a liquid containing portion of the hollow interior of the tank. An economizer receiving a second flow of the refrigerant through an interior thereof is at least partially submerged in the liquid containing portion of the tank. The economizer forms a heat exchanging structure configured to exchange heat between the first flow of the refrigerant passing over an exterior of the economizer and the second flow of the refrigerant passing through the interior of the economizer. A desiccant is disposed in the liquid containing portion of the tank downstream of the economizer with respect to the first flow of the refrigerant through the hollow interior of the tank.
