OA-GZ Series
Principle The OA-GZ vertical cabinet-type air conditioning unit integrates the compressor, condenser, throttle device, and evaporator of the refrigeration system within a single vertical cabinet enclosure. Utilizing river, lake, or seawater as the cooling source, the unit operates its refrigeration system during summer to cool, dehumidify, and lower the temperature of the air inside the cabin. During winter heating, the unit's electric heater operates to warm and raise the temperature of the cabin air. In transitional seasons, the unit's fan operates to provide ventilation for the cabin. The unit possesses the functions of cooling, dehumidification, heating, and ventilation. Additionally, a fresh air inlet is provided on the side of the unit, allowing for the direct introduction of outdoor fresh air.
