Annex 34 – Thermally Driven Heat Pumps for Heating and Cooling

Introduction

The goal of Annex 34 is to reduce the environmental impact of heating
and cooling by the use of thermally driven heat pumps. It will be based
on the results from Annex 24, ”Absorption Machines for Heating and
Cooling in Future Energy Systems”, and cooperate with the IEA-SHC task
38, “Solar Air-Conditioning and Refrigeration”.

• Start date: 1 October 2007

• End date: 31 December 2011

Objectives

One of the main objectives is to quantify the economic, environmental
and energy performance of integrated thermally driven heat pumps in
cooling and heating systems in a range of climates, countries and
applications. From this, those areas and applications with the greatest
environmental benefit, the best economics and the greatest market
potential will be identified.

Project manager and participating countries

Germany is the Operating Agent.

The other participating countries are

Austria,

Canada,

Italy,

Norway,

Switzerland,

The Netherlands,

United States

More countries are showing interest and sending observers, e.g. UK, Sveden, Romania

Activities

The following task-sharing activities are planned to be carried out by
the participants:

• Task A - Market overview and state of the art
• Task B - Performance evaluation
• Task C - Apparatus technology
• Task D - System technology
• Task E - Implementation
  

Information

This website will be established.  Two workshops will be arranged within the annex.

Publications and results

The deliverables of the Annex will include:

• This Internet website.
• A description of a standard to determine COPs of thermally drivenheat pumps and sorption material properties.
• An online database about sorption materials for heat pumps and their properties.
  
• A reference guide describing presently available thermally driven systems with their applications. Existing software tools, their application and users' experience, will also be included.
  
• A final report describing the work carried out under the Annex.
  
• At least two workshops with complete proceedings.
