Efficiency

Efficiency of the heat pump depends on:

• source temperature (°C)

•  ground water 10°C

•  lake or river water 12°C

•  waste water 30°C

•  air -5 / +20°C

• required heating temperature (30 → 80°C°C)

Technology & efficiency

Target to reduce the absorbed power of the heat pump

Example – Quantum with Turbocor compressor

Oilfree centrifugal compressor

with magnetic bearings

= less friction, less resistance

= lower absorbed power

= higher efficiency

Compressor = the hart of every heat pump system

Challenge

• Further efficiency improvement of compressor technology – compressor hart of heat pump

• Further development of low temperature applications:

•  Design of the project

•  Equipment (indoor)

• Industrial high temperature (>70°C) applications request high pressure equipment

Applications - Case study Quantum Heat pump applications:

•  Tourism: swimming pools, wellness centres (temp: 30-35°C)

•  Space heating of buildings – heating by air distribution(temp: 45-50°C):

•  hospitals

•  office buildings

•  show rooms

•  shopping centres

•  Industry:

•  agriculture – ground heating

•  drying processes: e.g.: paper industry

•  production sanitary and cleaning water

Applications - Case study Swimming pool – Krumbach Germany

Figures – Water to water heat pump Quantum

•  Heating capacity: 686 kW

•  Power input: 106 kW

•  Free energy (580 kW) from river water

•  COP full load = 6,4

•  River water: +10°C

•  Pool water : +24°C

52% energy saving
