Editor of Solar and warmth Pump Systems for Residential Buildings
Jean-Christophe Hadorn started his career as a researcher on large-scale storage of solar heat in deep aquifers (1979–1981).

For several years, Mr. Hadorn has been appointed as External Manager of the Thermal solar power and warmth Storage Research Program by Swiss government.

Mr. Hadorn was a participant in IEA SHC Task 7 on “Central Solar Heating Plants with Seasonal Storage” (1981–1985) and initiated Task 26 on “Solar Combisystems” (1996–2000).

He was Operating Agent of Task 32 on “Heat Storage” (2003–2007). Since 2000, he leads an engineering company and styles solar thermal and PV plants.

In 2010, he was chosen by a world committee of the IEA because the Operating Agent for the IEA SHC Task 44 “Solar and warmth Pump Systems” also supported by the warmth Pump Programme under Annex 38, a project that produced this book.

Introduction to Solar and warmth Pump Systems for Residential Buildings

This book is a few hybrid technology called “solar and warmth pump.” it’s basically the mixture of a system with a apparatus delivering heat to a building.

When the sun is shining, the collectors are going to be the first source of energy for the domestic predicament preparation and for space heating.

Furthermore, the daily solar production are often stored for future use for a couple of days. When the sun is a smaller amount abundant or when the solar storage is empty, the warmth pump will take over the duty.

The source of the first low-energy “heat” for the warmth pump to work are often air, ground, or water from a river or an aquifer.

A nice feature of the hybrid combination is that solar collectors also can be used because the provider of the first heat for the warmth pump. the 2 components will then operate within the so-called serial mode.

This book will analyze the behavior of the most combinations of solar and warmth pump, derive facts from practical projects, provide results from simulations and laboratory tests,

and draw conclusions supported 4 years of activity of a collaborative project developed under the auspice of the International Energy Agency.

This book is suggested to the HVAC (heating, ventilation, and air conditioning) industry, the HVAC engineers and students, energy systems designers and planners, architects,

energy politicians, manufacturers of solar power components, manufacturers of warmth pumps, standardization bodies, heating equipment distributors, and researchers in HVAC and building systems.

Producing heat from solar power is a longtime technology since the 1990s. the warmth pump technology known since 1930 is becoming a typical solution to heat buildings and prepare domestic predicament in many countries.

Both markets have shown growth since 2000, especially the warmth pump market noticeably in countries with a high share of hydroelectricity in their energy supply.

For some years, systems that combine solar thermal technology and warmth pumps are marketed to supply space heating and to supply domestic predicament .

The energy prices, the necessity to scale back the general electricity demand, or the strategy to maneuver to more efficient solutions for heating than the present ones, the ecu Union legislation, and future scenarios calling for more renewable energies have driven the change.

Strong initial development of a mixture of solar and warmth pump started some years ago with the assistance of early work from industry and research bodies during a few European countries.

Innovative companies have shown success stories during this early period and still promote the benefits of solar and warmth pump combinations supported real experience.

The IEA Solar Heating and Cooling Program (SHC) launched in 2010 a 4-year project called Task 44, “solar and warmth pump systems.”

This was a joint effort with the IEA apparatus Program (HPP) under the name “Annex 38” to contribute to a far better understanding of SHP (for “solar and warmth pump”) systems.

It is anticipated that the electricity cost will increase on the earth within the future, thanks to CO2 cost considerations and scarcity of energy resources.

Solar photovoltaics might change the image if the technology is massively adopted. But still, highly efficient heat pumps reducing the electricity demand are going to be needed to substitute the fossil heating solutions that dominate the planet energy market within the 2010s.

Combinations with solar collectors can increase the general performance of a apparatus and can therefore even be a chic solution of choice.

There are scientific and technological issues in integrating solar collectors and warmth pump machines. The complexity lies in having two variable sources that ought to work together optimally.

Heat storage management and control strategies also are of prime importance for optimal design. This book will present the challenges and a few solutions altogether aspects.

T44A38 has concentrated its efforts on electrically driven heat pumps, not because other techniques like sorption machines aren’t possible but because no participants during this international activity presented a project with a thermally driven machine.

Foreword to Solar and warmth Pump Systems for Residential Buildings

The steady growth of solar thermal systems for quite three decades has shown that solar heating systems are both mature and technically reliable.

However, solar thermal systems have usually been sold as an add-on to a standard predicament or space heating plant .

In the future, we’d like to develop hybrid systems that provide an entire heating plant supported renewables, one that’s ready to cover 100% of the heating demand of buildings. One very promising possibility is that the combination of solar systems and warmth pumps.

This book shows alternative ways during which these two technologies are often combined, and it presents the trail to high-performance hybrid systems.

The book is that the results of collaborative international work within the Solar Heating and Cooling Programme and therefore the apparatus Programme of the International Energy Agency (IEA).

It is an excellent pleasure on behalf of me , as a former chairman of the IEA SHC Executive Committee, to introduce this book. The international work has led to some interesting findings on solar and warmth pump combinations supported monitored data and therefore the use of simulation.

The book presents of these findings and therefore the methodologies needed to assess the energy performance of such combinations. it’s a crucial contribution to the body of knowledge domain on renewable heat that the IEA has been supporting for over 40 years.

I am sure that the reader will find new knowledge and galvanizing ideas for future-oriented hybrid heating systems supported renewables.
