Product for Heating & Process Heating BROAD ABSORPTION HEAT PUMP Function Low temp. waste heat recovery Application • District heating • Process heating • Make up water preheating • Building heating Heating capacity 282 kW ~ 56,489 kW Energy sources • Steam • High temp. hot water • High temp. exhaust • Natural gas, town gas, biogas, diesel 2016 10 SI BRIEF INTRODUCTION TO BROAD ABSORPTION HEAT PUMP It is universally accepted that water flows from high position to low position, as well heat transfers from high temperature to low temperature. After the invention of water pump, water can be pumped to higher position with energy input. The same principle has been applied to heat pump. With power (electricity or thermal energy) input, heat can be moved from low temperature to high temperature. BROAD Absorption Heat Pump is a device driven by thermal energy (steam, hot water, exhaust or NG) which moves heat from low temperature to high temperature Absorption heat pump and chiller are like twins, because they have the same structure and working principle, but application is different. A chiller is used to make chilled water, and reject heat through cooling water. An absorption heat pump recycles heat from low temperature heat source, to produce high temperature water. For typical application, conditions such as low temperature heat source and heating demand are different, so absorption heat pump has a wide rarge of working conditions Compared with an electric heat pump, absorption heat pump has below advantages • Uses industrial waste heats, exhaust etc. as its input power • Uses water as refrigerant instead of CFCs, HCFCs, HFCs • Stable heating performance, endurable to ambient interruptions, no auxiliary heating equipments • Higher heating temperature, temperature difference, and wilder applications Absorption heat pump heating capacity comes from driven energy and low temperature waste heat with a heating efficiency 2~3 times higher than a boiler. The low temperature waste heat is common in industrial processes (like industrial cooling water, boiler exhaust gas etc.) and in nature world (like surface water, ground water etc.). BROAD Absorption Heat Pump is driven by waste heat with remarkable energy savings and payback. It has been installed in many countries around the world such as China, South Korea, Denmark, Belarus, Thailand and Austria 1 Typical Applications Thermal Power Plant Heat Pump — System Energy Saving by 15~20% • Low temp. waste heat: cooling water from power plant (15 ~ 30 ºC) • Driving heat source: steam from large scale steam turbine • Typical application: a paper factory in Thailand, recovers 3.3 MW waste heat from cooling water to produce 85 ºC middle temp. water to preheat make up water Two power plants in South Korea, recovers 48 MW waste heat from cooling water to produce 80 ºC middle temp. water for district heating Industrial Process Heat Pump — Heating Energy Saving by 41% • Low temp. waste heat: waste water heat from dyeing mill (about 30 ºC), cooling water from air conditioning (about 37 ºC), cooling water from steel works (about 40 ºC), heat from brewery process (about 50 ºC), heat from oil field (about 50 ºC), cooling water from coke plant (about 40 ºC or 23 ºC) • Driving heat source: steam from large scale steam boiler or small & middle - sized steam turbine, natural gas, high temp. hot water • Typical application: an eco-park in South Korea, recovers 24 MW heat from dyeing process to produce 83 ºC middle temp. water for district heating The world’s biggest daily chemicals manufacturer, which recovers 1.2 MW heat from air conditioning cooling water to produce 88 ºC middle temp. water for process heating A district heating company in Austria, recovers 2.3 MW heat from steel works cooling water to produce 85 ºC middle temp. water for district heating A famous Chinese liquor manufacturer, recovers 1.7 MW heat from brewery process to preheat boiler makeup water up to 80 ºC Exhaust Heat Pump — System Energy Saving by 8~15% • Low temp. waste heat: exhaust from boiler, gas turbine, direct fired absorption chiller etc. (60 ~ 180 ºC) • Driving heat source: natural gas, high temp. hot water, high temp. exhaust etc. • Typical application: a biomass district heating center in Denmark, recovers 3 MW heat from biomass boiler exhaust to produce 85 ºC middle temp. water for district heating 12 th National Games Center (China) recovers 2.3 MW heat from 2*3, 300 RT BROAD direct fired absorption chillers' exhaust to produce 60 ºC middle temp. water for building heating A district heating center in Beijing recovers 4.7 MW heat from 3*40 ton boilers’ exhaust to produce 60 ºC middle temp. water for district heating An energy plant in South Korea, recovers 24 MW heat from 2*77 MW gas turbines exhaust to produce 61 ºC middle temp. water for district heating 2
