Utilizing unused energy Absorption Heat-pump (Type 1: Heat Amplifier)


Due to the rising demand of reducing Carbon Dioxide; the active global warming gas to prevent global warming, various technologies are advanced to reduce energy year by year for different kinds of equipment such as heat generators and boilers, etc. However, independent equipment has its limitation, therefore to achieve CO2 reduction goal, it is essential to utilize all waste heat energy from all production facilities in factories and plants as a system.

To achieve this target, Hitachi enhances new features to its Absorption Heat-pump, enables the unit to deliver required high temperature hot water with the system that exploits well the waste heat (exhaust gas, drained water) generated from other production facilities. The system completes the favorable cycle and accomplishes the good reliability and high efficiency of factories and plants.

Absorption-type heat pump system

Absorption Heat-pump is a system to transfer heat from waste heat source to increase temperature of supplied hot water, helping in energy saving. In general process where low temperature source is used to produce chilled water, the system is called chiller system. On the other hand, in process that heat is used to generate higher temperature hot water, it is called heat-pump system.

Among these heat-pump systems, when compare heat reclaimed by using absorption heat-pump and by using boiler, the additional heat (energy) required by absorption system is far less. Moreover, the absorption system can provide much high temperature hot water when compare with compressor type heat-pump system.
