    Mitsubishi Heavy Industries Thermal
    Systems, Ltd.

    Recently, the reduction of carbon dioxide emissions has been required to prevent global warming, and in the case of packaged air conditioners, it is necessary to convert to a refrigerant with a low global warming coefficient and improve efficiency to reduce power consumption. On the other hand, there is strong request for downsizing and weight reduction of the outdoor unit due to restrictions of installation locations and ease of transportation and carry-in, which must be balanced with improvements in efficiency. Mitsubishi Heavy Industries Thermal Systems, Ltd. has developed the Hyper Inverter series of packaged air conditioners, which are compact, lightweight and highly efficient. This paper introduces the characteristics and specifications of the outdoor units.
