Abstract: An air conditioner and a method for controlling the same are disclosed. The air conditioner implements a multistage expansion scheme by implementing serial connection between electronic expansion valves including in the R410A refrigerant-based air conditioner, and thus guarantees an optimum compression ratio in all cooling/heating load regions. Therefore, although cycle characteristics are changed by changing R410A refrigerant to R32 refrigerant, the air conditioner optimizes the cycle simply by controlling a degree of opening of electronic expansion valves, respectively. As described above, since the cycle optimization is implemented using the multistage expansion scheme in which legacy electronic expansion valves are coupled in series, the design modification is minimized without design modification of requisite constituent elements such as a heat exchanger, system implementation is facilitated, resulting in high efficiency in cost and productivity.

Abstract: Disclosed is an interfacial polymer for a network used as a coupling agent in mixing of rubber-silica. More particularly, the interfacial polymer for a rubber-silica network is a block copolymer containing a copolymer of conjugated diene and vinyl aromatic monomers, in which when used as a coupling agent in the mixing of synthetic rubber and silica (an inorganic material), the polymer enhances silica dispersibility within the rubber, and improves compatibility and processability, resulting in considerable improvement in the dynamic property as well as the mechanical property of the rubber, and when used in a tire, etc., it enhances automobile braking performance and reduces rolling resistance.

Abstract: Disclosed are a novel chain transfer agent having a trichloromethyl functional group bonded at an end thereof, an end-modified styrene-butadiene copolymer prepared by using the chain transfer agent, and an organic-inorganic composite obtained by mixing the end-modified styrene-butadiene copolymer with silica. The disclosed end-modified styrene-butadiene copolymer has a high affinity with silica because its end is modified with a hydrophilic chain transfer agent. Thus, the organic-inorganic composite including the mixture of the copolymer with silica is useful as a material for the manufacture of rubber products such as a tire, a sole, a rubber hose, or a rubber belt.
