HFC/HCFC DX System Large amount of refrigerant charge, remain as main stream in developing countries

HFC/CO2 Cascade System Less amount of HFC charge than HFC DX system, lower global warming impact from HFC leakage

CO2 Booster System Large amount of CO2 charge, spreading in EU but efficiency drop in warmer area

<Transfer Pressure> Pressure to transfer CO2 Refrigerant

from Refrigeration unit to showcases

A new “2-stage expansion cycle” makes possible to control

Transfer Pressure (approx.6MPa) constantly through the year.

By Pressure Adjust Control Technology, ① Smaller footprint and lighter weight

② Workability improvement in the installation field

・Reduce plumbing weight (thinner pipe）

・Shorten construction time

(Welding/Operational adjust./ Airtightness test）

③ Line-up Expansion have become possible.

・Pressure to showcase fluctuate 5MPa～9MPa with the season.

・Airtight examination pressure of the construction plumbing 12MPa.

・Pressure to showcase is controlled constant about 6MPa in all season.

・The necessary refrigerant quantity in a refrigerating cycle is stable in all season.

・Airtight testing pressure of the construction plumbing 8MPa.

There is Panasonic you haven’t known yet.

“Ecology” is the serious issue in the cooling food industries,

especially supermarkets and convenience stores which are

running for 24 hours a day and 365 days a year. Recently, Non

Freon Refrigeration System adapted the natural refrigerant

(CO2) is making steady progress in Japan. Panasonic

developed it by unique technologies of 2-stage compression

rotary compressor & Split cycle, to aim at Zero Ozone

Depletion & Greenhouse Effect by 1/4000 compared to HFC

(R404A).

Panasonic was the first to adopt the natural refrigerant (CO2) in

refrigeration business in Japan.

That environmental performance is equivalent to about 67%

reduction per year in CO2 estimate.

Additionally, the remote monitoring and control services using

Cloud were set up to make facilitate management of energy

usage. We always pursue “Environmentally friendly products”

from a various angles.
