OA-DC-ZY Series
Principle： The OA-Z direct-expansion packaged air conditioner integrates the compressor, condenser, throttle device, and evaporator of the refrigeration cycle into a single unit. Utilizing the water-source heat pump principle, it uses rivers, lakes, or seawater as the cooling or heat source. During cooling, the water cools and condenses the refrigerant, and the fan delivers cold air. During heating, the water heats and evaporates the refrigerant, and the fan supplies warm air.

OA-DC24-1.5ZB Series
Principle: The OA-DC24-ZB is a cooling unit specifically designed for small unmanned vessels. This system integrates a compressor, condenser, throttling device, and evaporator into a cohesive unit to provide cooling and temperature reduction for cabin equipment. Utilizing rivers, lakes, or seawater as the cooling source, the device circulates water to absorb and carry away heat from the system, while the fan delivers cool air.

OA-TC-ZY Series
Principle: The OA-TC-ZY compact integrated chilled and hot water unit adopts a patented dual-compressor design. It divides the original single-unit capacity of 36,000–60,000 Btu/h into two stages for startup, reducing the minimum cooling and heating capacity to 18,000–30,000 Btu/h, making it highly suitable for yacht applications. In summer cooling mode, the unit supplies 7°C chilled water for cabin cooling. In winter heating mode, it provides 45°C hot water for cabin heating.

OA-BPZ Series
Principle: The OA-BPZ direct-expansion integrated inverter air conditioner combines the compressor, condenser, throttle device, and evaporator into a single unit. The system is also equipped with a solenoid four-way reversing valve, which allows switching between cooling and heating modes. This air conditioner operates based on the water-source heat pump principle, utilizing rivers, lakes, or seawater as the cold and heat source. In cooling mode, the rivers, lakes, or seawater cool and condense the unit, and the fan blows out cold air. In heating mode, the rivers, lakes, or seawater heat and evaporate the unit, and the fan blows out warm air.
