Technical Resources

Five things characterise a Stream technical resource. Working from first principles, integrating across disciplines and mindsets, innovating conservatively to gain the advantage of technology, rigorous cost analysis, and consideration for ecology.


Design, Research and Optimisation

The refrigeration vapour compression cycle is a complex field when assessed in detail, due to the intereaction of change of state, volume, heat content and enthalpy of refrigerants. It is a field where there is much scope for better understanding and implementation, and we have tools in house to measure and adjust thermal flows. We also have the support of an excellent network of suppliers who are prime sources for production of bespoke coils, heat exchangers and fan units.

Thermal design

Heat flow in Materials and Fluids

Thermal transfer through materials is critical in the understanding of extreme environments, even more so than in buildings where there is often a degree of tolerance.


Measurement, Recording, Reporting

The noise and vibration levels present in an environment are a critical part of the conditions that humans are called upon to experience, enjoy, operate in and even endure! We have the experience, equipment and procedures to record, measure, analyse, report on and resolve issues and problems around this sphere.

Human Environment


Having an understanding of the function of the human body and mind and the conditions that it is subject to is an essential precursor to the delivery of appropriately designed temperature, humidity, noise and vibration control. It is equally essential to differentiate between the stresses and overall effect on cognitive function that occurs in an office environment, as distinct from, for example, a dance floor, oil rig or operational military vehicle.

Air Movement

Fans, Air pressure, Ductwork

Delivery of airflow to the point of need is a critical strategy in the design of our climate control systems, and a large percentage of the capacity of the system and its energy use can be saved if the air and cooling are ducted direct to the body or equipment. An example of this is our ManPAC system, which delivers carefully controlled cooling to the soldiers upper body, greatly reducing the cooling required.

Other Technologies

Heat pipe, Thermo-electric, Evaporative, BioMedical

We are always on the lookout for new technologies in the field of thermodynamics that can be employed in the search of the perfect human environment. Examples of some recent developments are the use of thermo electric coolers, heat pipe transfer technology and evaporative coolers.
