5 DRAIN PIPING WORK

Piping material

•For laying pipes underground, use hard vinyl chloride pipe. VP25 (Inner diamater Ø32mm)

Piping and cautions

•Set drain side of pipe at downward slope. (1/100 or more)

•Be sure to apply thermal insulation (foaming polyethylene, 10mm-thickness or more) for pipes passing through the room.

•Adhere the connecting sections with vinyl chloride agent surely so that no water leakage is caused.

•Apply adhesive agent without unevenness around the portion approx. 40mm from the end of hard polyvinyl-chloride pipe.

•Push the vinyl pipe in the drain socket completely up to the end of the socket.

•Do not apply strength to the connecting part until the adhesive agent has dried and hardened.

•Support the piping with hanging bracket so that the force is not applied to connection sections of pipe and pipe is not waved.

NOTES :

•Do not make slack or trap at halfway across piping.

•Set pipes so that the end of drain pipe is not dipped in water, and also keep space 50mm or more to the ground.

•After piping work, check if water drains smoothly.

•Hole should be made at a slight downward slant to the outdoor side.

•When connecting extension drain hose, insulate the connecting part of extension drain hose with shield pipe.

Do not put the drain hose end into water or drainage.

Thermal-insulating process

•After checking water drain, be sure to apply the thermal-insulating for connecting portion of the pipes.

•Apply taping so that there is no clearance on the fitting part of thermal-insulator of the main unit with the insulator procured locally.

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.
