• To present a compilation of the roles compact
  heat exchangers (CHEs) can play in heat pumping
  equipment.
• Directed at minimising both direct and indirect
  effects of the equipment on the local global
  environment due to manufacture, operation
  disposal of the plant.

7

• Methodology based on the following tasks,
• Market research identification of
  commercially-available CHEs across all sectors
• Evaluation of performance data, both published
  and (optionally) by experiment
• Evaluation of properties and operating limits of
  CHEs
• Information sharing technology transfer see
  Deliverables

8

• The project runs for three years.
• Start date (contract) 1 November 2006.
• 3 Annex Meetings (05/07, 05/08 and January 2009)
• Final Meeting with Conference/Workshop in the UK
  3 Sept 09 Brunel University, London
• (after MNF 2009)
• Reports 08/07, 08/08 and 10/09

9

• UK Contribution
• Technical summary based upon UK Good Practice
  Guides and a CHE Training Package.
• Market survey
• Results from UK project Boiling and Condensation
  in Micro-Channels
• Coordination of Report

10
CHE GUIDANCE

• This document will contain descriptions of
  relevant CHE types (principally for process heat
  pumps), cost data, sizing data, comments on
  fouling and how to calculate the heat exchanger
  performance.
• Includes plate-fin heat exchangers, PCHEs,
  plate heat exchangers.
• Based upon UK Good Practice Guides and a CHE
  Training Package.

11
ADVANTAGES OF CHEs

• Generic Advantages of Compact Designs
• The main benefits of using compact heat
  exchangers are
• Improved heat exchanger thermal effectiveness.
• Closer approach temperatures.
• High heat transfer coefficients and transfer
  areas per
  exchanger volume.
• Smaller size.
• Multi-stream and multi-pass configurations.
• Tighter temperature control.
• Energy savings.
• Reduced inventory volume and hazard risk.

FOULING RESISTANCE DATA ON PROCESS SIDE OF HEAT
EXCHANGER
Values may differ for different types of heat
exchanger
13
Generic data for CHEs

• Typical performance data is tabulated in terms
  of
• Process fluids
• Overall heat transfer coefficient
• Cost expressed as /(W/K)
• For various types and ratings of CHEs
