BITZER ECOLINE compressors
The influence of refrigeration technology on the environment is increasingly a topic of discussion. The energy efficiency of refrigeration systems is a key factor here. The lower the energy consumption, the lower the effect on the environment and life-cycle costs. For this reason, several regions (including within the EU) have already introduced or are preparing guidelines and standards requiring a minimum level of energy efficiency.
The approval of new refrigerants with a low greenhouse effect mean that you are well equipped to meet the requirements of EU F-gases regulations. BITZER has always placed a great deal of value on the economic efficiency of fits compressors and several years ago introduced the BITZER ECOLINE series, specially optimised for use with R134a. R134a has excellent properties, especially for normal cooling and heat pumps. These also include exceptionally good economic efficiency, moderate pressures (reduced leakage) and the lowest GWP value of all non-flammable HFC refrigerants. This enables an exceptionally affordable seasonal energy efficiency, even when using BITZER ECOLINE compressors in very low condensation temperatures. Studies have shown that hybrid designs using R134a with normal cooling and cascades with CO2 freezing systems in supermarket applications have particularly good eco-efficiency (optimum lifecycle costs and TEWI) as well as low energy consumption.
The BITZER ECOLINE series has since been expanded with additional versions for universal use with different refrigerants within the same wide range of applications. Refrigerants include: R134a, R404A, R407A, R407C, R407F, R507A, R450A, R513A, R1234yf, R1234ze(E), R448A, R449A, R452A and R22. These compressors are designed for use with “low GWP” HFO refrigerants and HFO/HFC mixes. A system designed for use with R134a can be later switched to use e.g. R513A (A1 Drop In). When considering flammability, some systems can also later use R1234yf. The performance value (COP) of the BITZER ECOLINE models has been improved by up to 12% compared to the previous series. This has been achieved by various means, including further improvements to the valve plate, reduced flow losses and compressed gas pulsation as well as the use of specially adapted and exceptionally efficient motors. The compressors are designed for use with frequency converters (CE1 to CE2 from 30 to 70 Hz, CE3 to BE6 from 25 to 70 Hz). This allows the cooling power of the system to be precisely adapted to current requirements.
