A compressor (22) comprises a housing (50) having a first port (26) and a second port (28). A male rotor (52) has a working portion (64) having a plurality of lobes (110) of a count (NM) and at least a first shaft portion (62) protruding beyond a first end (68) of the male rotor working portion and mounted for rotation about a first axis (500). A female rotor (54) has a working portion (66) having a plurality of lobes (112) of a count (NF) and mounted for rotation about a second axis (502) so as to be enmeshed with the male rotor working portion. An electric motor (56) is within the housing and has a stator (58) and a rotor (60) mounted to the first shaft portion. The compressor has no additional compressor rotors. The lobe count of the male rotor is less than the lobe count of the female rotor. A combined lobe count (NM + NF) is at least fifteen.

Embodiments are directed to an installation of a first tube made of a first material on a heat exchanger that is different from a second material associated with a second tube of the heat exchanger. The first tube is coupled to the second tube via a porous layer associated with the first tube. A signal is measured between the first tube and the second tube. The measured signal is logged as data. Information associated with a corrosiveness of an environment in which the heat exchanger is located is obtained based on the data.

An evaporator heat exchanger includes a first tube bank having an inlet manifold and a plurality of first heat exchanger tubes arranged in a spaced, parallel relationship. A second tube bank includes an outlet manifold and a plurality of second heat exchanger tubes arranged in a spaced, parallel relationship. An intermediate manifold fluidly coupled the first tube bank and the second tube bank. A distributor insert arranged within the inlet manifold includes a first dividing element configured to define a plurality of first refrigerant chambers therein. A second dividing element is arranged within the intermediate manifold and is configured to define a plurality of second refrigerant chamber therein. Each second dividing element is arranged at a position substantially identical to a corresponding first dividing element. Each second refrigerant chamber is fluidly coupled to the same portion of the first heat exchanger tubes and a corresponding first refrigerant chamber.

A refrigeration system for a refrigerated cargo container includes two or more refrigeration circuits, each circuit configured to cool a compartment of the refrigerated cargo container. Each circuit includes a compressor (38) to compress a gaseous flow of refrigerant, a gas cooler (40) in fluid communication with the compressor to cool the compressed flow of refrigerant, and an evaporator (46) located at the compartment and in fluid communication with the gas cooler and the compressor. An electrical generator (34) is operably connected to the compressor of each circuit to drive the compressors and a control system operably connected to the electrical generator and the two or more circuits. The control system is configured to calculate a maximum electrical power generated by the generator, calculate a target electrical load of the components of each circuit, and distribute the available electrical power from the generator to meet the target electrical load of each circuit.
