Compact Cube MCHV-P1800AE for Commercial Use
Factor 1.771: Performance Factor 1.00:
Environmental Load Factor 1.771
Lightweight, compact and high part load performance
The Compact Cube is a heat pump chiller that produces cold and hot water used in the air conditioning systems of buildings and factories. The device is driven by electricity, so compared to absorption chillers powered by fuels like gas, the Compact Cube produces cold and hot water while emitting less carbon dioxide.
The Compact Cube features both high efficiency and compactness. It incorporates the following new technologies, which make it ideal not only for new air conditioning systems, but also for converting from existing absorption chillers.
- New V-flow unit format (an industry first)
- R410A refrigerant (an industry first for 40+ horsepower chillers)
- Includes DC inverter-driven scroll compressor
(an industry first for 40+ horsepower chillers) - New refrigeration cycle with two evaporating temperatures (an industry first)
- Water dispersion system uses minimal water
- Improved part load efficiency using COPMAX control (an industry first)
Reasons for Eco-Product Certification
- Factor rating of 1.38 or more
Detailed equipment data
- Lighter unit weight, improved performance and fewer resources used thanks to new specifications for the compressor and heat exchanger and a new optimized layout for the unit panels. 24% lighter than the previous Mitsubishi Electric model (2,150 kg→1,640kg).
*Previous model: CAH-J 1800A (60 Hz) used for comparison
- Superior energy efficiency due to improved efficiency of devices that make up the unit, including the compressor, heat exchangers and airflow fans, and more sophisticated refrigeration cycle control.
- Cooling COP raised by 66% compared to the previous Mitsubishi Electric model (2.59→4.3).
- Heating COP raised by 17% compared to the previous Mitsubishi Electric model (3.29→3.85).
*Previous model: CAH-J1800A (60 Hz) used for comparison
- Product uses HFC refrigerant R410A, eliminating ozone-depleting substances (previous Mitsubishi Electric model uses HFC refrigerant R22).
- Eliminated the use of the six substances specified by the EU's RoHS directive.
*Previous model: CAH-J1800A (60 Hz) used for comparison
The Compact Cube air-cooled heat pump chiller achieves a high rated cooling efficiency of COP 4.8 (40 horsepower model) as a result of optimized heat exchangers and its water dispersion method. Use of an inverter-driven scroll compressor provides energy efficiency throughout the year, not just during rated operating hours. Converting from an absorption chiller would reduce carbon dioxide emissions by 58% and power consumption by 48%.
Compact Cube's small size was achieved through high-density mounting of the heat exchangers. It is the lightest chiller in the industry in the 180 kilowatt class (cooling capacity).
The product's high energy-efficient performance was recognized and it was awarded the Energy Conservation Center Chairman's Award at the Fiscal 2008, 19th Energy Savings Awards.
