Brand Introduction of Panasonic Compressors
Panasonic is a leading global manufacturer of electronics and electrical appliances founded in 1918 and headquartered in Osaka, Japan. As a diversified multinational company, Panasonic’s product lines cover a wide range of fields from consumer electronics to industrial equipment. Among them, Panasonic has a deep history and technical accumulation in the development and production of compressor technology, and its compressor products are renowned for their high performance, reliability and environmental friendly features.

Brand Core Values of Panasonic

Innovation: Continuously investing in R&D and introducing new technologies and products to meet market demands.

Quality: Ensuring the excellence of each product through a strict quality control system.

Environmental protection: Committed to developing more environmentally friendly technologies to reduce the impact on the environment, such as the use of low GWP refrigerants.

Customer first: Providing comprehensive technical support and services to help customers solve problems and optimise system performance.

Core Technology Features
1. Energy efficient
Energy efficiency ratio (COP) of Panasonic scroll compressor is generally higher than 3.0, for example, 2V34S225AUA rotary compressor COP is 3.201.
The inverter compressor reduces start-stop losses through infinitely variable speed regulation, saving energy by more than 30%.

2. Low noise and high reliability
Adopting internal noise elimination structure (e.g. high and low pressure partition) and nitrogen gas pressure preservation technology, the operating noise is as low as 41 dB (refrigerator compressor).
The contactless design of scroll compressor reduces wear and tear, and the life expectancy can reach more than 10 years.

3. Environmentally friendly adaptability
Supporting a wide range of refrigerants (e.g. R22, R600a), and some new models are compatible with environmentally friendly refrigerants such as R410A.

Main Types of Panasonic Compressors
1. Panasonic Rotary Compressors
Characteristics: Compact size, low noise, high energy efficiency, suitable for small and medium-sized air-conditioning systems. Panasonic rotary compressors achieve gas compression through the eccentric rotation of the rotor and cylinder, with simple structure and smooth operation.
Typical applications: Domestic air conditioners, commercial small refrigeration equipment.
Working principle: The rotor rotates eccentrically in the cylinder and compresses the gas to high pressure area by centrifugal force, simple structure and suitable for small power scenario.
Common models:

Model	Horse Power(HP)	Capacitance (μF)	Cooling Capacity (W)	Input Power (W)	Energy Efficiency Ratio (COP)	Applicable Voltage	Weight (kg)
2V34S225AUA	2HP	60	5810	1815	3.201	220-240V	18
2V36S225BUA	2.5HP	50	6140	1980	3.101	380V	21

2. Panasonic Scroll Compressors
Characteristics: High precision fit, non-flexible adjustment design, high and low pressure spacer to reduce noise, toothed top sealing ring to enhance sealing, high energy efficiency ratio (above 3.0), suitable for medium and large refrigeration systems.
Typical applications: Central air conditioning, industrial refrigeration units.
Working principle: The moving scroll disc rotates around the static scroll disc (not self-rotating), forming a crescent-shaped closed chamber, and the chamber shrinks in volume when moving from outside to inside, and the gas is compressed to high pressure and then discharged. The axial flexible design avoids friction and improves efficiency.
Common models:

Model	Horse Power(HP)Capacitan	Displacement (cm³/rev)	Cooling Capacity (50Hz)	Refrigerant	Supply Voltage	Weight (kg)
C-SBR235H38A	7HP	110.2	19.2kW	R22	3-phase 380-415V/50Hz	23
C-SB353H8A	4.5HP	77.4	13.5kW	R22	3-phase 380-415V/50Hz	21
C-SB373H8F	5HP	85.5	15kW	R22	3-Phase 380-415V/50Hz	23

3. Panasonic Inverter compressors
Characteristics: Adjusting the speed through inverter technology, adapting to different load demands, with remarkable energy-saving effect (e.g., the combined power consumption of refrigerator NR-EW55CPA-W is only 0.95kWh/24h).
Typical applications: High-end household air conditioners, inverter refrigerators.
Working principle: Adjusting the motor speed through frequency converter, dynamically matching the cooling demand, reducing temperature fluctuation and energy consumption.
