ECOi_VRF_V1_2009
ECOi - 2 and 3 pipe electric VRF systems
Since its formation in 1958, SANYO Air Conditioners has been at the forefront of innovation with its market-leading research and development program. From the world’s first heat pump air conditioner in 1960 to the first 3 pipe VRF system in 1989, SANYO continues to deliver leading technology combined with the reliability and customer service that you would expect from a global brand like SANYO.
Benefits
Ease of installation
R410A has a higher operating pressure with a lower pressure loss than previous refrigerants. This enables smaller pipe sizes to be used and allows reduced refrigerant charges.
Simple to design
SANYO recognise that designing, selecting and preparing a professional VRF quotation can be a time consuming and costly process, especially as it is often also a speculative exercise. So we have designed proprietary software which is quick and easy to use and produces a full schematic layout of pipework and controls, as well as a full materials list and performance data.
Easy to position
The compact design of the ECOi outdoor units means that they fit into a standard lift and are easy to handle and position when on site. The small footprint and modular appearance of the units ensure a cohesive appearance to an installation.
Off-coil temperature control
SANYO ducted units offer the unique advantage of being able to offer off-coil temperature coil as standard. This allows designers to select units using an off coil temperature between 7°C and 22°C. This allows room environments to be cooled without subjecting its occupants to cold drafts or uncomfortable conditions. This is achieved without any extra controls or wiring to each unit.
Wide selection and connectability
With 15 indoor model styles available, ECOi systems are the ideal choice for multiple small capacity indoor unit installations, with the ability to connect up to 40 indoor units to systems of 24HP or greater.

Easy to control
A wide variety of control options are available to ensure that the ECOi system provides the user with the degree of control that they desire, from simple room controllers through to state of the art BMS controls.
Simple to commission
Simple set-up procedure including automatic addressing of connected indoor units. Configuration settings can be made from an outdoor unit or via a remote controller.
Accurate capacity control
To ensure that the compressor capacity is matched to building load as accurately and efficiently as possible, SANYO has designed its range of 2 and 3 way ECOi systems to operate with DC inverter and high efficiency fixed speed compressors. The system selects the most efficient compressor to operate by dynamically monitoring the building load and choosing the best compressor combination to run.
Easy to maintain
Each system allows the use of prognostic and diagnostic controls routines, from refrigerant charge control through to complex fault code diagnostics, all designed to reduce the speed of maintenance calls and unit down time.
Lower running and life cycle costs
SANYO ECOi VRF systems are amongst the most efficient VRF systems on the market, offering COPs in excess of 4.0 at full load conditions. The system is also designed to make sure that we reduce the running cost of each system by using our unique road map control routine to ensure that the most efficient combination of compressors are running at any one time. Improved defrost sequencing also reduces running cost by defrosting each outdoor coil in turn when conditions allow.

New PAC2 System Design Software
Designing a system for VRF (ECOi and GHP) and PACi Commercial Split Systems has never been easier
SANYO has identified the importance of ever increasing demands for fast and accurate responses to customer requests in our industry. More and more emphasis is being placed upon energy-efficiency in our marketplace. The ability to calculate cooling/heating loads and produce information of actual design conditions is a major advantage to any architect, consultant, contractor or end user.
SANYO understands the ever changing and demanding industry we are in and we are pleased to announce the launch of the next generation of our system design software program. The new advanced PAC2 system design software has been customised to make any selection and design process as quick and easy as possible. The software features a version of AC Calc Lite. This allows small building loadings to be accurately calculated and directly imported into the PAC2 software.
The design package utilises system wizards and import tools to enable both simple and complex systems to be created. In addition, the system will allow outdoor and indoor units to be dragged and dropped on an interactive desktop. This allows users to create everything from realistic floor plans with detailed piping and wiring schematics to send out with quotations, through to installation guidance drawings.
The new PAC2 system software can be used for all SANYO ECOi, GHP and PACi systems.
Features include:
•AC Calc Lite (included in the package)
•Easy to use system wizards
•Auto piping and wiring features
•Converted duties for conditions and pipework
•Auto CAD (DXF) export
•Detailed wiring and pipework diagram
The new PAC2 system software can be used for all SANYO ECOi, GHP and PACi systems.
