HEAT EXCHANGER SOLUTIONS FOR HEAT PUMPS

A SUSTAINABLE AND INDEPENDENT HEATING METHOD

Climate change drives us to look for alternative heating methods. Heat pumps are one of these developing methods and can be used for commercial applications like heating and cooling buildings, houses, supermarkets, swimming pools a well as water. 

There is also a shift to industrial applications and large units that are used for the generation of process heat for several industrial processes like in the chemical and food & beverage industry. 

Last but not least high capacity heat pumps can be used to boost district heating grids.

The efficiency of a heat pump is defined by it's coefficient of performance (COP). The COP is a ratio of useful heating (or cooling) 
a heat pump will produce, given a certain energy input. The higher the COP value, the higher the efficiency. 

We can support you to manage heat and cold efficiently in industrial and residential areas. 

With innovative designed-to order Heat Pump Evaporators (also called False Load Cooler or Exterior Evaporator), customized coils as well as efficient plate heat exchangers, the CO2 footprint will be reduced significantly.

HEAT PUMP | WORKING PRINCIPLE

A heat pump consists of an evaporator, compressor, condenser and an expansion valve. 

The system allows for the transmission of heat from one location (Heat Source) at a lower temperature 
to another location (Heat Sink) at a higher temperature. 

  • The technology and efficiency of the heat exchangers significantly determines the COP value
  • The COP "Coefficient Of Performance" is the ratio of useful heating or cooling provided to work (energy) required 
  • The higher the COP value, the higher the efficiency
  • Heat Source is an important factor to determine the heat exchanger for the evaporator
  • Technology of the evaporator and condenser play a decisive role for the efficient operation of the system
  • Size of heat exchangers and heat pump affect energy coverage and part-load operation 
  • Condenser technology affects heat transfer and thus the efficiency of the system
