OA-Z Series
Principle: The OA-Z direct-expansion integrated air conditioner integrates the compressor, condenser, throttling device, and evaporator of the refrigeration cycle into a single unit. Operating on the water-source heat pump principle, it utilizes rivers, lakes, or seawater as cooling or heating sources. During cooling mode, the water cools and condenses the unit, and the fan delivers cold air. During heating mode, the water heats and evaporates the unit, and the fan supplies warm air.
