Absorption Heat Pumps

Jak to funguje

HEAT PUMP

A heat pump is a device that draws heat from a lower-temperature heat source to a higher-temperature cooler. Like any other pump, an external source is needed for pumping; the energy source can be either steam, hot water, exhaust gas or fuel.

Heat pumps drive the heat from a lower temperature to a medium temperature using high-quality energy. Heat pumps use steam, hot water, exhaust gas, fuel, geothermal energy or any combination of these heat sources to pump heat. Heat pumps save approximately 35% of heat energy.

Absorption heat pumps - Following Absorption cooling for comfort cooling and chilled water production, absorption technology can also be applied to heat pumps to ensure hot water or steam production.

Operating range

  • Output: 0.25–40 MW
  • Hot water temperature: up to 90°C (194°F)
  • High-quality heat source: Exhaust gases, steam, hot water and liquid/gaseous fuels (individually or in combination)
  • COP: 1.65–1.75
  • 4–10 bar.g Steam (pressure)
  • Low-temperature heat sources (30°C – 60°C):

Low-temperature heat sources (30°C – 60°C):

•Water from a cooling tower
•Condensate from industrial process

High-temperature heat sources:
•Dry saturated steam (1-10 bar.g)
•Overheated water (130°C – 180°C)
•Flue gas (275°C – 600°C)
•Natural gas

Hot water production for users up to 90°C, COP 1.65–1.75
