HEAT ELECTRIFICATION TECHNOLOGIES: THE TRANSITION TO CLEAN HEAT

Turboden's LHPs are not just about providing heat.

They are instrumental in driving the shift towards more sustainable and efficient energy systems:

  • Empowering district heating: By integrating LHPs into district heating systems, Turboden significantly mitigates reliance on fossil fuels, thereby reducing CO2 emissions and promoting cleaner urban environments.
  • Boosting industrial energy efficiency: LHPs are adept at capturing and repurposing low-grade heat for higher temperature industrial applications, enhancing operational efficiency in sectors such as refinery and petrochemical, chemical and pharmaceutical, food processing, and pulp and paper.
  • Carbon Capture Sequestrastion (CCS).

With Large Heat Pumps, Turboden is at the forefront of delivering tailored solutions that not only improve energy efficiency but also underscore the company's commitment to fostering a sustainable future. These initiatives align with global efforts to cut emissions and enhance energy independence.

Explore how Turboden's innovative heat pump technologies, including our comprehensive lineup of industrial solutions, can revolutionize your energy management strategy. Our dedicated team focuses on crafting solutions that go beyond meeting efficiency and sustainability objectives.

HEAT PUMP WORKING PRINCIPLE

The heat pump uses a medium-to-low temperature heat source to vaporize a suitable organic working fluid in the evaporator (1->2).

The organic fluid vapor increases its pressure in the compressor (2->3), which is coupled to the electric motor, thus consuming electricity.

The vapor is then condensed in the condenser (3->4), where it heats the medium-to-high temperature heat user resulting as the outcome from the system.

The organic working fluid is then laminated (4->1), reducing its pressure and temperature and completing the closed-cycle operation.

Heat carriers suitable as heat source and user (non exhaustive list):

  • Liquid (water, thermal oil, process streams …)
  • Vapor (steam, chemical mixture, …)

MECHANICAL VAPOR RECOMPRESSION

Mechanical vapor recompression (MVR) system, acting as an open cycle water heat pump, increases both the temperature and the pressure of a water stream, to generate steam at specific conditions needed.

The MVR technology finds its application either as a bottom technology for large scale heat pumps, to reach higher temperature output, or stand alone when high temperature water (or low pressure steam) is available as heat source.

Typical applications are related to the supply of high temperature steam in industrial processes within different industrial sectors, such as the distillation processes in the petrochemical industry or the cristallization process in the food and beverage industry.
