Air conditioning innovator launches VRF system that enables installers to commission it without opening the covers.
Toshiba has unveiled its latest VRF heat pump system, the SMMS-e which claims to set new benchmarks in efficiency and ease of use for installers and commisssioning engineers.
The hands-free commissioning is achieved with Toshiba’s proprietary Wave Tool Technology (WTT), a wireless commissioning and performance validation tool which enables engineers to read and write data to the condensing unit using a smart phone, without making physical contact.
It uses the technology of Near Field Communication (NFC) to transmit data between the outdoor unit and the engineer’s smart phone, enabled by touching their smart phone onto the NFC tag located on the outdoor unit.
The manufacturer says this both simplifies commissioning and reduces the amount of time spent on-site, enabling the service engineer to send system data via e-mail back to the office for analysis.
The SMMS-e claims a market leading ESEER of over 7.0, thanks to a Toshiba-built rotary compressor, which uses a two-stage compression process and increased rotation speed, for up to 50 per cent higher displacement volume than its predecessor systems. The enables a higher capacity to be obtained from a smaller compressor, Toshiba says. The compressor includes the ability to adjust rotational speed in near seamless 0.1Hz steps.
The new VRF features what Toshiba calls a three-way variable heat exchanger, enabling the VRF’s control system to decrease or increase heat transfer capacity depending on outdoor conditions. It also is claimed to be the only heat pump VRF to have continuous heating, with no requirement to stop during defrosts, thanks to hot-gas bypass control, which simultaneously defrosts outdoor heat exchanger coils.
