MARINE HVAC-R

BRONSWERK engineers work to meet each individual client’s needs, whether it’s an HVAC-R system for a tanker, container ship, ferry, tug, yacht or work boat. After a thorough assessment of your objectives and requirements, our engineers design the best HVAC-R solution for your vessel. Air conditioning systems on marine vessels generally can be divided into one of four basic types, determined by how the final cooling and heating are attained within the space. We design your optimum system by using various combinations of these four basic types of A/C systems, depending on your needs.

ALL-WATER SYSTEMS
ALL-AIR SYSTEMS (high or low-pressure)
AIR-AND-WATER SYSTEMS
DIRECT EXPANSION (DX) SYSTEMS

Your complete HVAC-R solution includes:

• Heat load analysis
• Conceptual, basic and detail system design
• Tailored equipment design and manufacturing to meet special needs
• Procurement of components and materials
• Installation and/or on-site supervision (when required)
• Testing and commissioning of HVAC-R system
• After-sales service and spare parts (worldwide)
• Warranty

Our team of engineers, detail designers, project managers and site supervisors is at your service. Small- and large-scale marine HVAC-R projects receive equal priority and customer care. Our support continues throughout the entire project – from advice if the ship design changes, to after-launch warranty and service. All of our projects are held up to rigorous quality standards. BRONSWERK relies on its project roadmap and the Project Management Body of Knowledge (PMBOK) method to ensure that we meet your highest expectations and deliver your system on-time and on-budget. The PMBOK is process-based, giving our client a descriptive overview of all accomplished processes.  

Multiple systems for different environments
and conditions.

ALL-WATER SYSTEMS

All-water systems are those with fan coil and unit ventilator or valance-type room terminals. Air is supplied by an inlet through the bulkhead or by infiltration. Cooling and dehumidification are achieved by circulating chilled water through a finned coil in the unit. Heating is provided by supplying hot water through the same or a separate coil.

System Advantages (+)

1. Flexible and readily adaptable to GA requirements.
2. Provides individual room control.

System Disadvantages (-)

1. No positive ventilation is provided unless bulkhead openings are used.
2. No humidification is provided.
3. Seasonal change over is required.
4. Maintenance and service work has to be done in the occupied areas.
5. Extensive water piping.
6. Limited noise control.

ALL-AIR SYSTEMS (HIGH OR LOW-PRESURE)

An all-air system provides complete sensible and latent cooling capacity in the cold air supplied by the system. Heating can be accomplished by the same air stream, either in the central system or at a particular zone. All-air systems are for applications in which the only cooling medium used directly within the conditioned space is air. They may be arranged in various ways for transmitting and distributing the air to and within the space, as well as controlling the space temperature and humidity conditions. Central air-handling units can provide heating and cooling to multiple compartments. The outside air is mixed with the return air from the conditioned space.

Individual adjusting of temperature can be done manually by opening / closing the supply air terminal or by local reheating. Outside air is mixed with return air from the compartments, at a ratio of approximately 40 % outside air and 60 % return air.

System Advantages (+)

1. The central plant is located in unoccupied areas, thereby facilitating operating and maintenance, noise control and choice of suitable equipment.
2. Seasonal changeover is simple and readily adaptable to climatic control.
3. Gives a wide choice of zonability, flexibility, and humidity control under all operating conditions.
4. Allows good design flexibility for optimum air distribution, draft control, and compartment requirements.
5. Well suited to applications requiring unusual exhaust makeup.
6. Adapts to winter humidification.
7. Improved air quality.
8. Control of noise levels.

System Disadvantages (-)

1. Requires additional duct clearance.
2. Air balancing requires great care.
3. Accessibility to terminals demands close cooperation between naval architects and mechanical and structural engineers.
