Toshiba’s lighter condensing units
Toshiba Air Conditioning (a division of Toshiba Carrier UK Limited) has introduced a new range of compact outdoor condensing units, designed to be easy to carry and install.
The Series 4 units are as much as 8kg lighter than previous models, representing a reduction of some 11%, a major advantage for installers transporting and installing the units.
This enables units to be installed one above another, in a double-deck configuration, saving space on buildings and outdoor plant areas.
Much of the weight reduction has been made possible by the development of a new twin rotary DC compressor, which is lighter but more powerful than the one it replaces.
The new condensers offer night set-back operation, limiting sound during sensitive periods by up to 10dB(A), and a saver function that can suppress the upper limit power consumption between 50 to 100% in 1% increments, boosting efficiency.
Overall efficiency has been improved by up to 10%, depending on the model, with the SEER value for the 2hp unit raised from 5.89 to 6.14.
Operational temperature range has been increased from 43 to 46ºC, and units are suitable for use with 50 or 60Hz power supply, opening up opportunities for further applications.
