World premiere: BITZER EXPANDER unit subcools without any additional electrical energy
Higher capacity and efficiency for CO2 systems
(PresseBox) - Nuremberg/Sindelfingen, 16.10.2018. BITZER is presenting a world premiere at this year?s Chillventa: with the BITZER EXPANDER subcooling unit, the specialist for refrigeration and air-conditioning technology makes CO2 refrigeration systems over 20 per cent more energy-efficient ? both in retrofits and new systems. An EXPANDER unit prototype will be on display at BITZER trade fair stand 326 in Hall 7 from 16 to 18 October 2018.
BITZER has developed a component that boosts efficiency specifically for supermarkets and logistics specialists in the form of the EXPANDER: at an ambient temperature of 32critical CO2 systems. Installation is quite simple and there?s no need to redesign the refrigeration system, which can be a complex process.
Reduced system complexity
Thanks to the EXPANDER unit, CO2 can now also be used more efficiently in hot climates. The new BITZER development is suitable for both retrofitting existing systems and designing new ones. Combined with BITZER ECOLINE+ reciprocating compressors, for instance, the EXPANDER unit represents a premium solution for outstanding eco-efficiency and optimised energy efficiency for transcritical CO2 systems. The EXPANDER unit works much like classic external subcoolers. The internal subcooling unit comprises a control valve, a heat exchanger and the heart of the system: an expander-compressor unit. The EXPANDER unit relaxes the primary mass flow, whilst the energy generated in the same unit compresses the subcooler mass flow and feeds it back before the gas cooler ? without any additional electrical energy. Thanks to the compact dimensions and simple mounting behind the gas cooler, the unit can be easily and affordably integrated into many different CO2 systems.
An important partner in the development of the BITZER EXPANDER unit is ALDI Stion systems with BITZER reciprocating compressors for transcritical CO2 applications, exploiting many options for energy savings.
