  • Publication number: 20220314750
    Abstract: Proposed is a vehicle air conditioner, which performs cooling and heating by supplying cold air and hot air in an interior of the vehicle. The vehicle air conditioner includes an intake unit installed at an engine room and configured to suction and blows internal and external air to the interior, a heat exchanger unit configured to cool or heat and supply air blown from the intake unit, a case cover installed on an outer surface of the intake unit to cover the intake unit, and a case soundproofing member installed between an intake case of the intake unit and the case cover and configured to block noise that is transmitted to the intake case from the outside of the case cover.

  • Patent number: 10995212
    Abstract: The present invention relates to a thermoplastic polyether ester elastomer (TPEE) having a hard segment and a soft segment and a method for preparing the same and, more specifically, to a thermoplastic polyether ester elastomer and a method for preparing the same, wherein a unit derived from an anhydrosugar alcohol derivative with improved reactivity derived from biomass is contained in the soft segment, and thus through the adjustment of the content of the anhydrosugar alcohol derivative, elastic characteristics and physical characteristics (for example, hardness, etc.), which are important characteristics of an elastomer, can be favorably maintained, the melting point variously required in the molding process of a final product can be easily controlled, a problem of depletion of, especially, petroleum resources as finite resources, can be solved, and environmental friendliness can be improved.
