An energy-efficient, space-saving, low-cost, waste-heat-utilizing ventilating air conditioning apparatus uses a honeycomb rotor having a function of adsorbing or absorbing contaminants such as carbon dioxide and VOC gas. The honeycomb rotor is disposed in a rotor rotating device having at least a processing zone and a re-generation desorption zone. Air to be processed is passed through the processing zone to remove contaminants such as carbon dioxide to produce supply air. Water is directly sprayed or dropped into a heat exchanger provided at an entrance of the re-generation desorption zone to evaporate the generated water film by heating. The generated saturated steam is introduced for desorbing carbon dioxide and pollutants, and the stream is discharged the stream outdoors. The ventilating air conditioning apparatus can operate without the energy loss associated with ventilation.

The present invention also provides an oxygen absorbent containing the unsaturated double bond-containing compound and a resin composition containing the same. Provided are an unsaturated double bond-containing compound represented by general formula (I), an oxygen absorbent containing the same, and a resin composition.

Metal organic resins, composite materials composed of the metal organic resins, and anion exchange columns packed with the composite materials are provided. Also provided are methods of using the composite materials to remove metal anions from a sample, methods of using the metal organic resins as fluorescence sensors for detecting metal anions in a sample, and methods of making the metal organic resins and the composite materials. The metal organic resins are amine-functionalized metal organic frameworks and their associated counter anions. The composite materials are composed of metal organic resin particles coated with organic polymers, such as alginic acid polymers.

A honeycomb rotor recovery and concentration device recovers carbon dioxide gas from flue gas and the like. A carbon dioxide sorption honeycomb rotor is rotated in a casing that is separately sealed at least into a sorption zone and a desorption zone, and the honeycomb in the sorption zone is brought into contact with a raw material gas containing carbon dioxide in a wet state to sorb carbon dioxide gas. A desorption circulation circuit circulates from an outlet to an inlet of the desorption zone. Water supplied to a heater in the circuit is evaporated to form saturated steam, which is supplied to the desorption zone. In the desorption zone, carbon dioxide gas is desorbed by contact with the saturated steam. The design may make it possible to use low-temperature exhaust heat, and this may achieve reduction in size, high performance and high efficiency at the same time.

A ventilating air conditioning apparatus has energy efficiency without energy loss associated with ventilation, has high space, saves space, and is low cost. The ventilating air conditioning apparatus has a honeycomb rotor having a function of adsorbing or absorbing contaminants such as carbon dioxide. The honeycomb rotor is disposed in a rotor rotating device having at least a process zone and a desorption regeneration zone. The processed air is passed through the process zone to remove contaminants such as carbon dioxide and the air is supplied. Saturated steam is introduced into the regeneration desorption zone to desorb contaminants such as carbon dioxide and is discharged to outdoors.
