Air conditioning and heat pump solutions

In a warming world, air conditioning is essential for homes, businesses, hospitals, data centers, laboratories, and other critical establishments. However, it's a dilemma: 2019's space cooling emitted 1 Gt CO2, consuming 8.5% of global electricity. Alfa Laval's plate exchanger technology with low GWP (Global Warming Potential) refrigerants offers sustainable cooling for buildings, boosting chiller energy efficiency.


Why you should choose Alfa Laval for air conditioning solutions

  • Alfa Laval’s brazed heat exchangers offer unparalleled thermal efficiency and mechanical performance to ensure optimal condensation and evaporation.
  • With nearly 100 years of expertise, Alfa Laval's heat exchangers deliver efficient heat pump solutions backed by pertinent certifications.
  • Our proactive R&D teams help you stay at the forefront, offering the latest sustainable heat transfer solutions for the HVAC industry.
  • We have a global presence, with local service centres worldwide, ensuring that you receive efficient service no matter where you are.
  • Alfa Laval can optimize the brazed heat exchanger for OEM customers according to specific applications and system requirements.

Trends in the industry

Air conditioning alone consumes a staggering 70% of peak residential electricity demand on hot days in the US and Middle East. The United Nations Environment Programme (UNEP) and International Energy Agency (IEA) report anticipates a sharp uptick in space cooling demand ahead.

As air conditioning grows more vital globally, its associated issues amplify—unless rectified.
A massive change is currently underway in the refrigerants market. Driven by environmental concerns, legislation is pushing a gradual phase out of traditional refrigerants in favour of new alternatives with lower global warming potential (GWP).

Alfa Laval addresses this in two ways. Enhanced plate heat exchangers annually save 860 GWh of electrical power.
Moreover, our new heat exchangers are adaptable to your chosen refrigerant and optimized for natural, low-density, low-GWP types.

In my view, the F-Gas Regulation represents the biggest departure related to refrigerant bans in the last 30 years. Until now, there was always a substitute in place that met all relevant safety criteria. As a refrigeration contractor today, however, you can’t get around flammable refrigerants like propane or R1234ze. You have to be able to handle them.”

Maintaining an optimal indoor climate

Within the air-conditioning chiller unit, diverse manufacturers integrate Alfa Laval brazed plate exchangers as liquid evaporators and/or condensers. For larger structures, additional Alfa Laval heat exchangers are incorporated. Gasketed plate heat exchangers, with minimal temperature difference, serve intermediate roles in heating and cooling systems. Aloft, roof-installed air-liquid coolers or condensers effectively remove excess heat.
