Refrigerant Piping

Piping kit used for the conventional refrigerant cannot be used.

Use copper pipe with 0.8 mm or more thickness for Ø6.4, Ø9.5, Ø12.7.

Use copper pipe with 1.0 mm or more thickness for Ø15.9.

Flare nut and flare works are also different from those of the conventional refrigerant. Take out the flare nut attached to the main unit of the air conditioner, and use it.

3 SELECTION OF INSTALLATION

Before installation

Be careful to the following items before installation.

Length of refrigerant pipe

<SM560AT-E>

Length of refrigerant pipe

 

connected to

Item

indoor/outdoor unit

 

 

 

20m or shorter

Addition of refrigerant is

unnecessary at the local site.

 

 

 

*21m to 30m

<Addition of refrigerant>

Add 20g of refrigerant for every

 

1m of pipe which exceeds 20m.

 

 

*Caution at addition of refrigerant

When the total length of refrigerant pipe exceeds 20m, add 20g/m of refrigerant and the maximum total length of pipe is 30m.

(Max. amount of additional refrigerant is 200g.)

Charge the refrigerant accurately. Overcharge may cause a serious trouble of compressor.

<SM800AT-E>

Length of refrigerant pipe

 

connected to

Item

indoor/outdoor unit

 

 

 

20m or shorter

Addition of refrigerant is

unnecessary at the local site.

 

 

 

*21m to 50m

<Addition of refrigerant>

Add 40g of refrigerant for every

 

1m of pipe which exceeds 20m.

 

 

*Caution at addition of refrigerant

When the total length of refrigerant pipe exceeds 20m, add 40g/m of refrigerant and the maximum total length of pipe is 50m.

(Max. amount of additional refrigerant is 1200g.)

Charge the refrigerant accurately. Overcharge may cause a serious trouble of compressor.

Air purge

For air purge, use a vacuum pump.

Do not use refrigerant charged in the outdoor unit for air purge. (The refrigerant for air purge is not con- tained in the outdoor unit.)

Electrical cabling

Be sure to fix the power cables and indoor/outdoor connecting cables with clamps so that they do not contact with the cabinet, etc.

R410A specifications

Toshiba R410A is a highly regarded refrigerant known for its efficiency and environmental benefits. This hydrofluorocarbon (HFC) mixture is widely used in various air conditioning and refrigeration applications due to its excellent thermodynamic properties. One of the standout features of R410A is its superior energy efficiency, which contributes to lower energy consumption and reduced CO2 emissions in HVAC systems.

One significant advantage of R410A over older refrigerants, such as R22, is its lower ozone depletion potential (ODP). R410A has an ODP of zero, making it a more environmentally friendly choice. This characteristic aligns with global initiatives aimed at protecting the ozone layer and promoting sustainable practices. The shift to R410A has been supported by government regulations in many countries, phasing out older, more harmful refrigerants.

Toshiba has incorporated advanced technologies in its R410A compatible products, enhancing performance and reliability. Among these technologies is the inverter technology that allows the compressor to operate at variable speeds. This functionality leads to improved temperature regulation, reduced noise levels, and further energy savings. Inverter systems provide precise control over the cooling and heating processes, allowing for a comfortable indoor environment while minimizing wastage of energy.

R410A also exhibits excellent heat transfer properties, which boosts cooling capacity. This feature makes it suitable for large-scale HVAC systems, including commercial and industrial applications. Its high-pressure characteristics enable the design of more compact and efficient components, allowing for smaller units and easier installation.

Furthermore, Toshiba's dedication to technological innovation is visible in its commitment to research and development. The company continuously strives to optimize systems that utilize R410A, focusing on reliability and longevity. This includes improved compressor designs, enhanced heat exchangers, and the integration of smart controls that adapt to the varying load conditions in real-time.

In terms of safety, R410A is classified as non-toxic and non-flammable under normal conditions, making it a safe choice for use in residential and commercial settings. However, it is important to note that R410A operates at higher pressures compared to traditional refrigerants, necessitating proper equipment design and handling procedures.

In conclusion, Toshiba R410A stands out in the market for its energy efficiency, environmental safety, and technological advancements. It is an ideal refrigerant for modern HVAC applications, contributing to both comfort and sustainability. As the industry continues to evolve, R410A remains a pivotal element in the quest for responsible and efficient refrigeration solutions.
