Understanding Control, Management and Optimisation of Complete System





Glen Dimplex engages with strategic suppliers early in the product development cycle,enabling:

- Early access to new technologies- Clear understanding and agreement of commercial imperatives

New Product Development Cycle

Shortened productdevelopment cycles

of typically 12 months

12 months

Engagement withsuppliers 24 months in

advance of product launch

12 months

Partnering For Rapid Innovation





Examples of Glen Dimples and Research LedInitiatives for Performance Improvements

• CoP Booster• System Design• Optimised Heat Exchange





COP-Booster

CoP Booster

Improved CoP

• Optimised with refrigerant 410a• Ensures minimum overheat of refrigerant gas• Compressor protected (no liquid)





Improved CoP

•

Oversized heat exchanger• Larger Casing• Less and shorter defrost cycles• Increased CoP• Lower sound emissions due to reducedairflow

System Design





Optimised Heat Exchange

Improved CoP

•

Water source heat pump (open loop)• No external heat exchanger required toprotect the heat pump• Direct use of ground water Safe due tospecial designed stainless steal heatexchanger•

Better SCoP
