Light Commercial Multi System

Light Commercial Multi System

Designed for light commercial multi applications such as shops, restaurants and small offices; the R-410A system is inverter-controlled for maximum comfort and top efficiency, COP up to 4.1 in heating mode. It also allows individual control of up to four indoor units of varying types and sizes, supports flexible outdoor unit placement (wall, roof, even indoors) due to extended piping lengths, and is extremely quiet.

Efficient outdoor unit can be mounted on roof, wall or indoors
The CMSQ outdoor unit is equipped with an inverter-controlled scroll compressor driven by a high efficiency motor. Inverter control ensures constant room temperatures and maximum efficiency, especially in partial load situations: EER to 3.71 in cooling mode and COP to 4.1 in heating mode.

A total piping length (from outdoor unit to all indoor units) of 200 metres is supported, with the outdoor unit itself able to be mounted against a wall or on a roof. With an external static pressure of 50 Pa, the unit can even be installed indoors. CMSQ also uses Daikin’s REFNET piping system for optimum refrigerant flow. Moreover, CMSQ has been designed to be extremely quiet, with sound levels as low as 57 dBA in normal operation or down to 45 dBA in night mode for the outdoor unit.

Individually controlled indoor units
Two types of indoor units are offered: a Roundflow cassette (FMCQ) and a concealed ceiling unit (FMDQ), both in a range of capacities from 5 to 12.5 kW in cooling mode. Up to four indoor units can be installed, in any combination of capacity and indoor type, with each unit individually controllable via its own infrared or hard-wired remote control. The indoor units operate at near silent sound levels: FMCQ down to 28dBA, FMDQ down to 30 dBA. CMSQ also optionally supports Daikin’s Intelligent Touch Controller and Intelligent Manager control systems.

The FMCQ Roundflow Cassette provides comfortable air discharge in all directions and supports 360° uniform airflow and temperature distribution. Horizontal air discharge ensures draught-free operation and the unit’s 23 different airflow patterns allow installation in corners or small rooms. Optional fresh air intake up to 20% is available and the unit’s decorative panel comes in 2 colours: white and white with white louvers for better integration in shop and commercial interiors.

The lightweight and compact FMDQ concealed ceiling unit blends with every interior. The unit fits flush against the ceiling, with only the air suction and discharge grilles visible. The air discharge grilles are adjustable, allowing uniform temperature distribution even in irregularly shaped rooms.

CMSQ is designed for applications with multiple rooms/areas such as shops, offices, restaurants etc. that require great flexibility in installation and control. A two-storey shop with a back office, for example, could be configured as follows. The top storey of the shop could have slightly different temperature settings from the lower storey. Different settings could also be used in the back office. This is all possible with the individually controlled indoor units. What’s more, the back office can be switched off when not in use. And if the back office is small, the asymmetric combinations allow choosing the capacity needed. CMSQ allows mixing the indoor types (cassettes and ducts) as well as the capacity classes of the indoor units.
