LABORATORY CAPABILITIES

Testing for Real Operating Conditions

Oulairuina brings acoustic, enthalpy-difference and low-temperature testing into an integrated laboratory setup. These complementary methods support the development and verification of HVAC equipment, from fan coil units to large air-conditioning systems.

Our laboratory documentation describes work to ISO 3745, GB/T 6882 and GB/T 25127, alongside other national and international standards. Testing covers sound power, thermal performance and operation in demanding conditions, providing data for equipment development and technical improvement.

DESIGN & COLLABORATION

Our Team

A Dedicated HVAC Design Team

Our technical team connects load calculations, system planning, detailed drawings and equipment selection with installation support and operating advice. We work across commercial buildings, industrial facilities, offices, medical laboratories, clean workshops and hospitality spaces.

HVAC engineers, coordinated MEP designers, load and energy specialists, BIM technicians and design optimisation staff contribute to each brief. Site conditions, building fabric, occupancy, process requirements and local climate shape the proposal from the outset.

Design reviews consider energy use, noise, service access, routing and investment together. Coordination with architectural, structural, electrical and water services teams helps resolve issues before work reaches the site.

Responsibility Through Delivery

Design staff stay involved in technical handover, site questions and commissioning support. Connecting the drawings with practical installation conditions helps the project team make informed decisions throughout delivery.

A Culture of Practical Engineering

Technical care, open communication and customer needs guide the way we work. Engineers discuss complex conditions early, share practical experience and review alternatives together. Our recommendations explain the operating and maintenance implications of each option, as well as its benefits.

Safety, energy efficiency and environmental considerations remain part of everyday design decisions. We aim to deliver systems that work reliably over the long term.

Different Skills, Shared Direction

Our team combines HVAC and building-environment specialists with engineers who understand installation, industrial ventilation, clean air systems and equipment selection. Digital design skills in BIM and coordinated services complement experience in site delivery and export projects.

This mix allows us to form a suitable working group for each application and bring several perspectives to demanding project requirements.

PERFORMANCE DEVELOPMENT

Laboratory Testing

Thermal Performance

Enthalpy-difference testing supports the evaluation of cooling and heating performance. Measurement data helps the team compare configurations and review how equipment responds to its intended operating conditions.

Environmental Testing

Controlled laboratory conditions support the study of equipment performance across temperature requirements. Testing informs product refinement and the review of thermal behaviour in demanding applications.

Airflow Verification

Airside testing examines the movement of air through the connected equipment and test setup. Alongside acoustic and thermal evaluation, it provides a practical basis for development and configuration decisions.
