Overview
The OA-GZH Series is a vertical cabinet water-source heat pump air conditioning unit that integrates compressor, condenser, four-way reversing valve, expansion device and evaporator into a single enclosure. It is designed for commercial vessel spaces such as passenger ships, workboats and offshore drilling platforms to provide cooling, dehumidification, heating and ventilation. The unit can use river, lake or seawater as the cooling source and includes a side fresh-air inlet for partial outdoor-air introduction.

Features

• Vertical cabinet surface-mounted design for easy installation and tidy appearance.
• High external static pressure suitable for ducted air distribution.
• Digital control system for straightforward operation and monitoring.
• Heat-pump configuration for energy-efficient heating and cooling.
• Corrosion-resistant, anti-vibration and anti-sway construction for marine environments.
• Intended for commercial vessels: passenger ships, workboats and offshore platforms.

Protection Features

• Water flow: water-pressure protection on river/lake/seawater side.
• Refrigerant pressure: high-pressure and low-pressure protection.
• Compressor & fan: overload and overtemperature protection including compressor overheating protection.
• Power supply: phase-sequence protection.
• Electric heater: overload, overtemperature and ground-fault (leakage) protection.
• Indicators: operation and alarm display.
