<\/div>Absorption Heat Pumps<\/h4><\/a><\/li><\/ul><\/div>
\nBrief Introduction to BROAD Absorption Heat Pump<\/span><\/strong><\/h3>\n
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.<\/p>\n
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:<\/p>\n
\u2022 Uses industrial waste heats, exhaust etc. as its input power
\n\u2022 Uses water as refrigerant instead of CFCs, HCFCs, HFCs
\n\u2022 Stable heating performance, endurable to ambient interruptions, no auxiliary heating equipments
\n\u2022 Higher heating temperature, temperature difference, and wilder applications<\/p>\nAbsorption 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.<\/p>\n
