Understanding Control, Management and Optimisation of Complete System

EUSEW 11-15 April 2011

High efficiency heat pump systems – from best practice to mainstream | 14-04-2011 | Sustainable Energy Week | Brussels

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 product development cycles

of typically 12 months

12 months

Engagement with suppliers 24 months in

advance of product launch

Examples of Glen Dimples and Research Led Initiatives for Performance Improvements

• CoP Booster • System Design • Optimised Heat Exchange

EUSEW 11-15 April 2011

High efficiency heat pump systems – from best practice to mainstream | 14-04-2011 | Sustainable Energy Week | Brussels

COP-Booster

CoP Booster

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

EUSEW 11-15 April 2011

High efficiency heat pump systems – from best practice to mainstream | 14-04-2011 | Sustainable Energy Week | Brussels

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

System Design

EUSEW 11-15 April 2011

High efficiency heat pump systems – from best practice to mainstream | 14-04-2011 | Sustainable Energy Week | Brussels

Optimised Heat Exchange

Improved CoP • Water source heat pump (open loop) • No external heat exchanger required to protect the heat pump • Direct use of ground water Safe due to special designed stainless steal heat exchanger •Better SCoP
