An absorber or desorber contains one or more micro-channels that have a 3-D structured heat-exchanging surface and a membrane on the microchannel situated distal to the 3-D structured heat-exchanging surface, where the membrane is permeable to a solvent of a solution employed in the absorber or desorber. The 3-D structured surface promotes mixing of hot and cold solution between the 3-D structured heat-exchanging surface and a vapor-exchanging surface proximal to the membrane. The mixing reduces the differences in concentration and temperature of the bulk solution and the solution at the vapor-exchanging surface to enhance the efficiency and rate of absorption or desorption of the solvent.

Disclosed herein a technique for producing a gas mixture for controlling an oxygen concentration in the interior of a container while reducing the overall weight of the apparatus. For this purpose, a gas mixture supply device is provided for a container refrigeration apparatus. The gas mixture supply device is provided with adsorption columns. If one of the first and second adsorption columns is supplied with air, the adsorption columns are pressurized, and nitrogen in the air is adsorbed onto an adsorbent. If air is sucked from the other of the first and second adsorption columns, the adsorption columns are depressurized, and nitrogen adsorbed onto the adsorbent is desorbed. A gas mixture including the nitrogen desorbed from the adsorbent is supplied to the interior of a container.

An absorption chiller includes a boiler with a vessel for storing a working fluid and a heat source configured to heat the working fluid. A first device is configured to cool the working fluid, and a second device is configured to cool the working fluid. A flow path is arranged to enable the working fluid to flow from the boiler through the first device, through the second device and back to the boiler. A first waste heat source is generated by the first device when cooling the working fluid. The first waste heat source is configured to heat the working fluid along the flow path after exiting the second device and prior to re-entering the boiler.

There is provided an absorption chiller including: a control unit configured to control opening and closing of the first control valve and an operation of the first pump, and a second supply flow path configured to supply the liquid inside the evaporator into the absorber; a second control valve opening and closing the second supply flow path; and a second pump configured to generate power to supply the liquid inside the evaporator into the absorber. After an operation of the absorption chiller is stopped, the control unit is configured to open the first control valve and operate the first pump such that a liquid inside the evaporator is mixed with the absorption liquid. Further, before the first control valve is opened and the first pump is operated, the control unit is configured to open the second control valve and operate the second pump.
