    Ι . Overview 1. DVM system series 1-1. What is DVM? The DVM(Digital Variable Multi) air conditioning system is operated by a variable-capacity compressor and is accommodated by multiple evaporators (indoor units). It is touted as the next-generation modular system in the world of high-efficiency air conditioning. lt has undoubtedly changed the face of cooling associated with high-storied buildings.

    1-2. Features of DVM (1) Customized air conditioner 1) Up to 16 indoor units can be connected to one outdoor unit. 2) Indoor units can be combined by various methods, according to each room’s use and shape. 3) There are several indoor units which can be applied; 1-way cassette type, 4-way cassette type, Ceiling, Duct (Low silhouette, Built-in, High pressure), Wall-mounted and Floor standing type.
  • Page 10 Ι . Overview 1. DVM system series (3) Variable compressor The world’s first PWM(Pulse Width Modulation) compressor controls the cooling & heating capacity automatically, depending on the load. 1) Principle of the digital compressor Composition A solenoid valve is installed for compressor´s loading / unloading between the upper part of the fixed scroll and the suction pipe.
  • Page 11 2) PWM (Pulse Width Modulation) valve PWM valve is the valve to take away the fixed scroll by lifting up through the difference of pressure after the digital scroll compress being connected to the outlet and inlet of suction. Therefore, the capacity of compressor is controlled automatically according to the operation status such as loading when the valve is closed or unloading when the valve is opened.
