OA-GZH Series

Principle The OA-GZH vertical cabinet-type air conditioning unit integrates the compressor, condenser, four-way reversing valve, 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 cabin air. During winter, heating is achieved through the operation of the unit's heat pump system to warm the cabin air. In transitional seasons, the unit operates in ventilation mode using its fan. The unit provides cooling, dehumidification, heating, and ventilation functions. A fresh air inlet is also provided on the side of the unit for the direct introduction of outdoor air.
