HFC-free refrigeration technology for the retail

(Currently a technical revolution is taking place in the refrigeration industry)

CLIMATECHNO

Bart van der Wekken


F- gas regulations

Proposal new F-gas regulation:

  • From 1-1-2016 ban on new installationswith R404A/R507 (GWP>2500)

  • From 1-1-2020 ban on allHFC’s in new installations

  • From 1-1-2017 ban on charging existing installations with R404A/R507

    Practical consequences:

  • Notwise building new installationswithR404A/R507 (GWP>2500)

  • Remodeling: considerationR404A/R507

  • Intermediate solution: R407F (GWP=1850)

  • Future= CO2


Natural refrigerants

Hydro Carbons (HC: e.g. Propane and Iso-butane)

  • Generally excepted in plug-in refrigeration cabinets/refrigerators (charge < 150 gr.)

  • Market is growing for indirect systems; systems located outdoors

  • High flammability

    Ammonia (NH3)

  • Well known in industrial refrigeration technology

  • High toxicity

    Carbon Dioxide (CO2)

  • Retail refrigeration technology

  • High pressure


Simplified scheme, Transcritical Booster CO2

  • Charge 100% CO2 (HFC-free)

  • Suitable for moderate climates

  • Simple system (compared to cascade)

  • For Dutch climate best solution

    • TEWI reduction up to 45%

    • Energy saving 15%


Centralised refrigeration systems for supermarkets

  • Transcritical CO2 Booster, with LT and MT cabinets, is the best solution for northern Europe (North of Paris)

Optimum high pressure

  • Temperature and pressure are in depended from each other

Source: Bitzer


Heat recovery

  • Heat recovery with CO2 booster installation/vriesinstallatie


CO2 Booster for high temperature climates

CO2 booster systems are less efficient at higher ambient temperatures

Two solutions:

  • Water spraying (reducing ambient temp. with about 5K, Tambient>28°C )

  • Additional subcooling system (R134a or HC)


COP Comparison


CO2 emissions per CO2 eq/kg/year

  • Dutch supermarket; sales area 1200 m2

  • TEWI:

    • GWP refrigerant

    • leakage

    • energy consumption

R404A Booster 10% leakage

CO2 Booster 10% leakage


Safety issues for CO2 installations

Cold room evaporator

AKV

Liquid line

Suction line

Check valve

Alarm unit

  • Leak detector in coldroom and machineroom

  • Alarm at 0,5% (5000ppm) CO2 MAC value

  • During an alarm the electronic expansion valve (AKV) is closed and only the refrigerant charge of the evaporater is leaking in to the room

Sensor leak detector


Safety issues

  • Discharge safety valves outside


CO2 Booster CE/PED certified (module H/H1)

  • PS 30Bar

  • PS 45Bar

  • PS 120Bar

Conclusions

Transcritical CO2 Booster best solution for HFC-free refrigeration technology in the retail.

  • Up to 15% less energy consumption

  • Up to 45% TEWI reduction

  • Suitable for heat recovery

    Initial costs higher compared to HFC technology

  • With increasing market share costs of CO2 components will decrease
