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.

CZ-18BT1U, CS-KE12NB41, CS-KE18NB4UW, CU-KE18NKU, CU-KE12NK1 specifications

The Panasonic CS-KE18NB4UW and CU-KE12NK1, along with the CS-KE12NB41, CZ-18BT1U, and CU-KE18NKU, represent a suite of advanced air conditioning solutions built with cutting-edge technologies designed to provide optimal comfort, energy efficiency, and air quality in various settings.

One of the standout features of this lineup is the inverter technology. Inverter air conditioners adjust the compressor speed to maintain the desired temperature efficiently. This leads to significant energy savings compared to traditional air conditioners, which tend to frequently cycle on and off, consuming more power. By continuously regulating the temperature, the Panasonic units not only save electricity but also prolong the lifespan of the compressor.

Another noteworthy characteristic is the nanoe™ technology integrated into some of these models. Nanoe™ technology uses hydroxyl radicals to purify the air, minimizing harmful bacteria and allergens. This makes the Panasonic units particularly suitable for users with allergies or respiratory issues, providing a cleaner and healthier indoor environment.

In terms of design, these models are sleek and compact, allowing them to fit seamlessly into any room decor, whether in a home, office, or commercial space. The quiet operation is another advantage, making them ideal for bedrooms and study areas where minimal noise is essential.

Furthermore, the CS-KE18NB4UW and CU-KE12NK1 offer a range of powerful cooling and heating capacities, making them versatile solutions for various climate conditions. The cold climate performance ensures consistent heating in colder regions, while the robust cooling capabilities make them perfect for hot summer months.

The user-friendly features include a smart remote control system, allowing users to adjust settings with ease from a distance. Some models are equipped with Wi-Fi capability, enabling integration with smart home systems for enhanced control and programmability.

In conclusion, the Panasonic CS-KE18NB4UW, CU-KE12NK1, CS-KE12NB41, CZ-18BT1U, and CU-KE18NKU air conditioning units exemplify innovation and efficiency. With their inverter technology, air purification features, compact designs, and smart functionalities, they stand out as ideal choices for maintaining comfortable and healthy indoor environments throughout the year.
