11.REFRIGERANT R410A:

SPECIAL PRECAUTIONS WHEN SERVICING UNIT

11-1. Characteristics of New Refrigerant R410A

11-1-1. What is New Refrigerant R410A?

R410A is a new refrigerant that contains two types of pseudo-non-azeotropic refrigerant mixture. Its refrigeration capacity and energy efficiency are about the same level as the conventional refrigerant, R22.

11-1-2. Components (mixing proportions)

HFC32 (50%) / HFC125 (50%)

11-1-3. Characteristics

Less toxic, more chemically stable refrigerant

The composition of refrigerant R410A changes whether it is in a gaseous phase or liquid phase. Thus, when there is a refrigerant leak the basic performance of the air conditioner may be degraded because of a change in composition of the remaining refrigerant. Therefore, do not add new refrigerant. Instead, recover the remaining refrigerant with the refrigerant recovery unit. Then, after evacuation, totally recharge the specified amount of refrigerant with the new refrigerant at its normal mixed composition state (in liquid phase).

When refrigerant R410A is used, the composition will differ depending on whether it is in gaseous or liquid phase, and the basic performance of the air conditioner will be degraded if it is charged while the refrigerant is in gaseous state. Thus, always charge the refrigerant while it is in liquid phase.

CAUTION

Ether-type oil is used for compressor oil for R410A-type units, which is different from the mineral oil used for R22. Thus more attention to moisture prevention and faster replacement work compared with conventional models are required.

Panasonic CS-KS12NB41 & CZ-18BT1U Refrigerant R410A Special Precautions When Servicing Unit, Components mixing proportions

CS-KS18B4UW & CZ-18BT1U, CS-KS12NB41 & CZ-18BT1U, CU-KS12NK1A, CU-KS18NKUA specifications

Panasonic has long been a reputable name in the HVAC (Heating, Ventilation, and Air Conditioning) industry, continuously innovating to provide efficient and sustainable solutions. Among their latest offerings, the CU-KS18NKUA, CS-KS18B4UW, CU-KS12NK1A, and CS-KS12NB41 split systems stand out for their advanced features and technologies designed to enhance user comfort while minimizing environmental impact.

The CU-KS18NKUA and CS-KS18B4UW units are high-capacity air conditioning systems that cater to larger spaces. One of their defining features is the inverter technology, which allows the compressor to adjust its speed according to the demand, leading to significant energy savings. The units operate quietly, contributing to a peaceful environment whether in homes or offices. Furthermore, the super-efficient energy consumption aligns with modern sustainability practices, reducing users' carbon footprints.

The advanced R32 refrigerant used in these systems is another highlight. R32 is known for its lower global warming potential compared to traditional refrigerants, making it an eco-friendly choice. These models are equipped with a powerful cooling capability while maintaining a compact and sleek design, seamlessly integrating into various interior styles.

In terms of indoor air quality, both models incorporate a multi-stage filtration system. This system effectively filters out dust, allergens, and harmful particles, ensuring cleaner indoor air. Additionally, the nanoe-G technology helps in deodorizing and purifying the air, enhancing the overall comfort and health of the environment.

The CU-KS12NK1A and CS-KS12NB41 models cater to smaller rooms but do not compromise on performance. They share similar inverter technology and energy-efficient characteristics as their larger counterparts, ensuring that users can enjoy a comfortable climate in a smaller footprint.

With an emphasis on user-friendly design, all these models come with intuitive remote controls, allowing for easy temperature adjustments and scheduling. Some units even offer Wi-Fi connectivity for remote access and monitoring via smartphone apps.

The CZ-18BT1U, often paired with these outdoor units, serves as an innovative air conditioning solution that supports energy efficiency and provides reliable cooling performance.

Overall, the Panasonic CU-KS and CS series units are ideal for consumers looking for modern, efficient, and environmentally friendly air conditioning solutions. Their combination of advanced technologies, user-centric design, and eco-conscious operation set them apart in the competitive HVAC market.
