New ProductHigh Performance Inverter Air
conditioner Series 2.5- 10
Horsepower-Class with HFC410A

Mitsubishi Heavy Industries, Ltd. (MHI) has launched
for sale a total of 176 types of "HYPER INVERTER" airconditioner series for stores with top level COP and piping
length in the industry including 5 types of 2.5-10 horsepower-class outdoor units and other indoor units sinceJanuary 2004. The high performance inverter air conditioner series adopt pseudo azeotropic refrigerant HFC410A
excelling the conventional HFC407C coolant in workability and serviceability. Together with the air conditioners(1.5-2.3 horsepower-class) put on sale in April last year,
the newly launched line-up of high-performance inverter
air conditioners for stores complete the HFC410A adoption program for all our air conditioners ranging from 1.5
to 10 horsepower-class.

addition of recovery control of the compressor lubricating
oil, actual plumbing length of 70 m for the types 2.5-4 horsepower-class, 100 m for the types 5-6 horsepower-class and
120 m for the types 8-10 horsepower-class, the top level
length in the industry, have been achieved to meet withthe customer's needs for the air-conditioning at suburban
shopping centers with larger floor area. The units havedrastically improved the restriction of the installation space
for the outdoor unit and provide higher freedom in design.

3. Enhanced Serviceability
In order to ensure quick response at the time of trouble
occurrence, an operation data retaining function has beenadded. Further, the ability to collect the on-site operation
data, simply by connecting the outdoor unit to a personal
computer and a printed-circuit board, has improved theserviceability of the unit.

1. COP level - Top in the industry
The inverter air conditioners in 8 horsepower-class haveachieved the average COP at cooling/heating of 4.20, thetop level in the industry, because the performance of compressor, DC inverter and heat exchanger is improved. Ahigh level of COP is obtained for other types of air conditioners as well, with all MHI units easily clearing thestandards stipulated in the Energy-saving Regulations(Laws) of Japan for fiscal year 2007. The 8 horsepowerclass air conditioners have successfully reduced the annual
electricity cost by 50% as compared with the constant-speed
units produced 10 years ago.

4. Full model change of outdoor units on 8- 10 horse8power-class
The outdoor units on 8-10 horsepower-class have undergone a full model change in design, with the fan air outlet
moved to the top, and the heat exchangers installed on all
four sides instead of solely on the rear side in conventional
units in order to improve the heat exchange performance.

Capacity

Because of the 1.5 times higher density of the HFC410A
coolant than the conventional coolant, the pressure loss in
the refrigerant pipe can be reduced. Further, because of
the improvement in electronic expansion valve control andCooling
