Abstract: There is provided a pipe connection arrangement for a heat exchanger and a method of connecting a pipe to a heat exchanger utilising a pipe connection arrangement. The pipe connection arrangement includes: a metallic block fitting; a flange for coupling to the block fitting; and a seal. The block fitting includes a bore extending therethrough for receiving a pipe for connection to a heat exchanger and the flange includes a bore extending therethrough for receiving the pipe. The block fitting includes a surface that faces the flange when the flange is coupled to the block fitting. The seal is configured for location between and for abutting both the surface of the block fitting and an annular collar of a pipe when it is connected by the pipe connection arrangement. The pipe extends through the bore of the flange and the flange is coupled to the block fitting.

Abstract: A separator (3), comprising: a housing (14); an inlet conduit (10), for admitting a flow (F1) of lubricant-charged gaseous refrigerant; a primary separation stage (31), configured for coarse separation of lubricant; a secondary separation stage (32), configured for fine separation of lubricant; a lubricant outlet conduit (11), for discharging lubricant; and a refrigerant outlet conduit (12), for discharging purified gaseous refrigerant.

Abstract: In a method for servicing an apparatus having a compressor (22) mounted to a support structure (32, 38, 40), a guide structure (102, 104; 202, 204) is placed adjacent to the support structure. The compressor is lifted from an installed position. The compressor is withdrawn by rolling the compressor along the support structure and guide structure.

Abstract: A refrigerated vehicle (2; 4; 6; 8) having at least one refrigerated compartment (10) comprises a refrigeration unit and at least one electrical power supply (60, 64). The refrigeration unit has a first module (14) mounted on the exterior of a refrigerated compartment (10), and which comprises: a compressor (28) having motor hermetically disposed therein, the motor being electrically connected to the at least one electrical power supply (64); a condenser heat exchanger (30); and at least one condenser fan assembly (42). The refrigeration unit also comprises a second module (16) mounted on the interior of a refrigerated compartment (10), and which comprises: an evaporator heat exchanger (50); and at least one evaporator fan assembly (52).
