TOSHIBA RAV LIGHT BUSINESS

Cooling & Heating: Guarantee of High Work Productivity

Hot summer days reduce performance and concentration. This can lead to a 70% decrease in work output. For machinery and technical applications, overheating can be fatal. TOSHIBA RAV units cool, heat, and dehumidify, ensuring ideal conditions (19-25°C, 40-70% humidity) year-round.

Dehumidification: Healthy Environment

Moist air damages health and building structures. Stuffy, hot conditions make breathing difficult, leading to fatigue and reduced performance. High humidity also promotes mold growth. Toshiba air conditioners not only cool but also dehumidify, reducing moisture levels.

Air Purification: Health Protection

Beyond dust and pollen, indoor air can be contaminated by volatile organic compounds (VOCs) from building materials, paints, plastics, and electronics. TOSHIBA air conditioning systems feature advanced filtration systems that neutralize up to 99% of airborne impurities, contributing to health protection.

Ventilation: Pleasant Environment

Most split air conditioning systems can be equipped with an optional fresh air intake port. This enhances indoor air quality, comfort, and human performance.

Meeting Requirements

For Operators: TOSHIBA systems focus on maximum efficiency and economy. Centralized control provides an overview of operation and consumption. A network of expert partners offers technical support from design to regular service.

For Users: TOSHIBA systems offer easy, intuitive control and precise temperature maintenance. Detailed settings and adjustable airflow direction ensure comfort without drafts. Quiet operation of sophisticated indoor units and user-friendly controllers with clear pictograms enhance the user experience.

Inverter Technology

Inverter air conditioning units adjust compressor speed to regulate cooling or heating output. When the actual room temperature approaches the setpoint, the inverter precisely reduces compressor speed to cover immediate heat loss or gain, saving energy and minimizing temperature fluctuations. This technology delivers only the required output, extending the lifespan of the system by avoiding frequent compressor start/stop cycles. TOSHIBA pioneered inverter technology in 1981 and has continuously refined it.

The graph illustrates how inverter technology maintains a stable temperature by adjusting compressor output, contrasting with systems that cycle on and off more frequently.

Toshiba's inverter control uses two operating modes: PWM (Pulse Width Modulation) for maximum efficiency at partial load and PAM (Pulse Amplitude Modulation) for maximum power and rapid temperature achievement.

Quiet Operation and Long Lifespan

The unique TOSHIBA Twin Rotary compressor, with its two chambers and counter-rotating cams, ensures maximum mechanical stability and minimal vibration, resulting in quiet operation and a long lifespan.

Stable Temperature, No Fluctuations

Inverter control adjusts TOSHIBA system output from 20% to 100%. This wide operating range maintains a stable temperature, offering greater consistency than systems that frequently cycle their compressors.

Two Control Modes – PWM & PAM

For rapid achievement of desired room temperature, PAM mode is activated, delivering high power. Once the target temperature is reached, the system switches to PWM mode for optimal energy efficiency and minimal consumption.

Nearly Continuous Regulation

Compressor speed, and thus system output, can be regulated almost continuously in minimal increments of 0.1 Hz, ensuring precise output adjustment and optimal energy utilization.

Precise and Clear Control

Special functions like "Soft Cooling" and "Dual Setpoint" provide maximum user comfort. Whether prioritizing comfort or efficiency, TOSHIBA systems deliver with easy operation and simple controls.

RAV – Solution for a Single Room

This solution is ideal for professional applications in offices, retail spaces, or technical rooms where reliability and continuous operation are essential. A single outdoor unit can connect to one to four indoor units of the same type, allowing for flexible distribution of cooling capacity within the room. Nominal cooling capacity for the RAV series ranges from 2.5 kW to 23 kW.

Advantages of the RAV Series

• Wide Application Range: Suitable for small server rooms to large supermarkets, adapting to required capacity and desired temperature.
