Further, the ejector module may be disposed outside an area overlapping with the engine when viewed from the vehicular front side, and the ejector module may be disposed outside of side members in a vehicle width direction.

This gas-liquid separator is provided with: a tank part which stores and separates a refrigerant; and a pipe connection part forming outlet/inlet ports for the refrigerant from the tank part. The pipe connection part has: a first connection part having a first connection pipe which guides the refrigerant to an expansion valve; a second connection part having a second connection pipe through which the cooled refrigerant returns; a third connection part having a third connection pipe which guides the refrigerant to a compressor; a fourth connection part having a fourth connection pipe which guides the refrigerant into the tank part from an outdoor heat exchanger; and a first flow path switching valve which allows the inside of the tank part to communicate with the third connection pipe during heating operations, and allows the second connection pipe to communicate with the third connection pipe during cooling operations.

An isothermal turbo-compressor-condenser-expander (ITCCE) arrangement includes heat-transferring fan blades that are mounted on, or surround, individual conduits to promote air exchange and heat transfer. The open framework rotates in free air to promote heat exchange. An ITCCE bladed assembly includes a driven central hub assembly with a first fluid coupling. A first inner plenum is in fluid communication with the fluid coupling. A plurality of compressor conduits extend radially, and pass fluid from, the first inner plenum to an outer plenum that acts as an equalizing line. A return path is provided to a second inner plenum from the outer plenum. The conduits can be formed as metal extrusions, including internal ribs separating a plurality of ports formed therebetween along an entire length of the conduits. The conduits can define an airfoil shape and/or are axially twisted, generating axial airflow. The return path can include return multiport conduits.

A centrifugal chiller in which a closed-cycle refrigeration cycle is formed by connecting a compressor, a condenser, an economizer and decompression means forming a multi-stage compression cycle, and an evaporator, with the refrigeration cycle being charged with a low-pressure refrigerant. The condenser and the economizer are integrated with each other by having a portion of their vessel walls form a shared wall, with the base surface of the economizer being positioned below the base surface of the condenser and above the base surface of the evaporator.

A refrigeration system includes a refrigeration circuit and a coolant circuit separate from the refrigeration circuit. The refrigerant circuit includes a gas cooler/condenser, a receiver, and an evaporator. The coolant circuit includes a heat exchanger configured to transfer heat from a refrigerant circulating within the refrigeration circuit into a coolant circulating within the coolant circuit, a heat sink configured to remove heat from the coolant circulating within the coolant circuit, and a magnetocaloric conditioning unit configured to transfer heat from the coolant within a first fluid conduit of the coolant circuit into the coolant within a second fluid conduit of the coolant circuit. The first fluid conduit connects an outlet of the heat exchanger to an inlet of the heat sink, whereas the second fluid conduit connects an outlet of the heat sink to an inlet of the heat exchanger.
