How It Works
HVAC design starts from a calculated load rather than an assumed one, because every downstream selection inherits the error if the load is wrong.
- 1
Heat load is calculated from building fabric, orientation, occupancy, lighting, equipment and fresh air requirements.
- 2
Design conditions are set against actual regional summer ambient rather than generic catalogue reference conditions.
- 3
System type is selected to suit the application: chilled water, direct expansion, packaged or precision cooling.
- 4
Equipment is sized at the real design condition, with derating applied where high ambient reduces rated capacity.
Built to
Solve
Engineered against the specific failures that cost operators downtime, contamination or wasted energy.
Asset protection
Equipment selected against temperate-climate catalogue ratings runs continuously at the top of its envelope in Gulf summer, which shortens compressor and coil life well before the design figures suggest.
Process integrity
In pharmaceutical, data centre and food production environments, temperature and humidity control is part of the process. Loss of control is a quality and compliance event, not a comfort complaint.
Operational efficiency
Oversizing is the most common fault in regional HVAC design. Oversized plant short-cycles, dehumidifies poorly and consumes more energy than a correctly sized system while being blamed for less.
Why Dolphin Group for
HVAC Design
Heat transfer specialists doing HVAC
Coils and heat exchangers are our core discipline, so the thermal element of an HVAC system is designed rather than selected from a table.
Designed for the climate it operates in
Forty years of Gulf operation means our selections reflect what equipment actually delivers here in August.
Manufacturing behind the design
Coils and fabricated components can be built in-house to suit the design rather than the design being constrained to available stock.
Key
Benefits
What sets hvac design from Dolphin Group apart, in specific and measurable terms.
- 1
Loads calculated, not assumed
Room-by-room calculation replaces rule-of-thumb sizing, which is where most oversizing originates.
- 2
Selections valid at 50°C
Capacity is verified at regional peak ambient, not at standard rating conditions that never occur here.
- 3
Part-load performance considered
Systems designed for how they actually run, which is below peak for most of the year.
- 4
Coils designed in-house
Coil design capability means the heat transfer element is engineered for the duty rather than taken from a catalogue.
- 5
Maintenance access designed in
Coil cleaning, filter changes and component replacement are considered while layout can still accommodate them.
- 6
Compliance documentation
Calculations and selections documented to support authority approval and commissioning sign-off.

View SectorFrequently Asked Questions
Air-cooled equipment rejects heat to ambient air, so as ambient rises the condensing temperature rises and capacity falls. A unit rated at standard conditions can deliver noticeably less at 50°C, which is why selections must be verified at real peak ambient rather than catalogue conditions.
No, it is a common and costly fault. Oversized plant short-cycles, which harms compressor life, controls humidity poorly because run times are too short for adequate dehumidification, and consumes more energy than a correctly sized system.
Yes, including temperature and humidity control, pressure cascade between classified zones and filtration to the required classification.
Yes, covering precision cooling selection, containment strategy and redundancy arrangement appropriate to the availability target.
Yes. Retrofit work usually begins by recalculating the actual load, which frequently differs from the installed capacity and explains the performance complaint.
We design and manufacture coils and heat exchange components in-house, and specify other equipment to suit the design. We are not tied to a single manufacturer.
