Annex 43 - Fuel Driven Sorption Heat Pumps

For residential and small scale commercial heating applications

Introduction

During the work in Annex 34 “Thermally Driven Heat Pumps for Heating and Cooling” there was a rising interest in the area of fuel driven sorption heat pumps and new products came closer to commercialisation. During the Annex 34 it was learnt that the fields of solar thermal cooling and fuel driven heat pumping need different measures for a wider market penetration, there was a common understanding to continue this work in two different Annexes or Tasks. Therefore, the work of Annex 34 regarding solar thermal cooling was continued within the IEA SHC Task 48 “Quality assurance and support measures for Solar Cooling” whilst the continuation of the fuel driven heat pumps part became a new Annex “Fuel driven sorption heat pumps”, proposed to the ExCo in March 2012. Annex 43 started officially in July 2013 with a duration of four years. A kick-off meeting was held in October 2013 in Freiburg with participants from six countries.

Objectives

The scope of the work under this Annex is the usage of fuel driven sorption heat pumps in domestic and small commercial or industrial buildings or applications. If applicable the additional possibility of supplying cold will also be considered. The main goal is to widen the use of fuel driven heat pumps by accelerating technical development and market readiness of the technology, as well as to identify market barriers and supporting measures. A field test and proposing performance evaluation figures and optimal system layouts are among the objectives of this Annex.

Advances in Heat Exchangers for Heating and Cooling

On the 8th March the SIRACH Network will visit the Kelvion research and development laboratory in Fareham for an event that will focus on advances in heat exchangers for heating and cooling.

The visit will include a tour of the state-of-the-art testing facility which includes testing equipment such as an air flow test rig, an inner calorimeter room, an environmental test chamber, as well as a connected, smaller air flow test chamber to enable testing of heat transfer coefficients.
