Marine HVAC Design Analysis
Our HVAC Design Analysis service allows us to create a digital twin of your vessel. We upload the drawings, determine the heat load of each and every room, design the ductwork and chilled water pipework, spec the AHU’s, chillers and pumps and then run calculations to review the design. Any red flags and we know about them immediately.
After spending decades designing, building and servicing HVAC systems for superyachts, we’ve learned that there is never a simple fix.
Clients require perfect temperatures and the dark art of HVAC means that both contractors and onboard engineers need a strong understanding of both air conditioning and refrigeration.
So many issues are caused by ‘not matching the loads’. Master Cabin too hot? The temperature of the fresh air make up units are too high or not being controlled at all. Or if it’s the VAV’s, the temperature of the supply air or the airflow rate coming into the room may be inaccurate.
Chillers pumping out the oil from the compressors – not enough load on the AHU’s in winter. The return water is too cold, lowering the evaporating pressure and slowing the compressor down. Also known as low delta T syndrome.
There are a huge amount of scenarios we could dive into that highlight the importance of ‘matching the load’. The work done by the equipment needs match the heat load it needs to cool. When there is an imbalance, things start to go wrong.
We provide state of the art energy reporting with hard facts on performance for plant optimisation, trouble-shooting and benchmarking.
Our HVAC Design Analysis tool covers:
- Heat load calculations
- VAV Min and Max airflow volumes
- Heat gains and losses
- Duct work sizing
- Chilled Water pipework sizing
- AHU flow rates
- Chiller sizing and flow rates
- …and more!
After sending us a PDF of your HVAC system, we’ll model your existing system and focus on resolving the key issues you’re experiencing.
Our detailed report includes varying scenarios, such as the heat load when the ambient temperature is 47’C and then again when its -5’C outside.
Therefore, identifying how many compressors should be running to match this load. We’ll know what the static pressure setpoint should be on your AHUs and what the volume of your chilled water system should be.
We specialise in the marine industry, so if you’re facing any issues with your HVAC system, we would love to support you by designing the perfect environment for your vessel.
