Toshiba VRF Systems – Maximum Reliability, Minimal Costs

Japanese company Toshiba has produced air-conditioning systems for over half a century. In 1977 Toshiba was the first to introduce microprocessor controlled air conditioners, and in 1981 the company produced an inverter air conditioner. In 1998 it launched Japan’s first air conditioner that operated on eco-friendly refrigerant R410A. Innovative technologies make it possible every year to improve the efficiency, comfort and reliability of air conditioning systems. In recent years Toshiba has created the world’s first VRF systems with three-inverter compressors in the outdoor unit.

What made it possible to increase the energy efficiency rating (EER) up to 6.26?
SMMS-i multizone systems, which capacity ranging from 14 to 150 kW, guarantee year-round air conditioning of the entire building. With every kilowatt of power consumed, SMMS-i produces up to 6.26 kW of cold and to 6.41 kW of heat. How does Toshiba achieve such energy efficiency?

1 The all-inverter VRF system contains from 1 to 4 outdoor units. 14HP and 16HP units are equipped with 3 DC inverter driven split compressors. Other units (8HP, 10HP and 12HP) have only 2 compressors. The new modern compressors developed by Toshiba Corporation allow improving both energy efficiency and comfort level.

2 When partially loaded, which in the conditions of Russian climate constitutes 85% of the mode VRF systems operate in, the energy performance rises by 40% and does not run down, as opposed to conventional scroll compressors.

3 The control system automatically adjusts the loads between the compressors and handles the consumption of the refrigerant.

4 The inverter drive, R410a refrigerant with high-pressure and freezeresistant polyester lubricating oil allow the system to heat rooms all year round, at ambient temperatures down to –20 ° C.

Even at subzero temperatures VRF system consumes twice less energy than an electric heater. The system allows using up to 48 indoor units. Large range of indoor units of 16 different types and 13 sizes such as cassette, duct, ceiling, wall, floor, fresh air intake units - allows you to choose the best system for almost any room.
