High End Residential Air Conditioning Solutions
Description

Daikin offer multiple solutions for residential cooling and heating, along with options for domestic hot water supply.

  • To create a desirable home environment all year round, Daikin Air Conditioning has Single and Multi-split systems (Super Multi NX), Variable Refrigerant Volume (VRV) systems with horizontal or vertical discharge options:

A Daikin Single-split is a system that consists of one indoor unit connected to outdoor unit and delivers air conditioning to single zone interior spaces at an affordable price.

A Daikin Multi-split Heat Pump (Super Multi NX) can heat or cool multiple rooms using only one outdoor unit and allows individual control of the air conditioning in each room. This not only
optimises comfort but saves on running costs that are kept low as only rooms requiring air conditioning are switched on.

A Daikin VRV system is a multi-split type air conditioner (one outdoor unit with multiple indoor units) that uses variable refrigerant flow control developed by Daikin to provide customers with the
ability to maintain individual zone control in each room with high energy efficiency. This is a more advanced solution than Super Multi NX.

  • To allow for fresh air supply without opening windows and energy savings, VAM heat recovery ventilation unit can be utilised in conjunction with single split ducted systems and the full VRV range of
  • indoor units.
  • To keep feet warm during winter, underfloor heating solutions are available via Daikin Altherma hot water heat pump systems with the option of an integrated hot water cylinder.
  • To provide an environmentally friendly alternative to the gas and direct electric hot water cylinders, a domestic hot water heat pump is also available as a standalone system for semi-instantaneous hot water supply.
  • To provide different levels of comfort from a single ducted unit to multiple areas, Daikin offers a zoning system — AirZone. This allows the control of airflow to each zone via motorised dampers.


Indoor units that often specified for this application are:

  • Bulkhead units (ceiling concealed) — Compact size to fit in wardrobe space
  • High Wall (wall mounted) — Designer series available in this range
  • Ducted Units (ceiling concealed) — complete with inbuilt drain pumps and allow for ductwork
  • Cassettes (ceiling mounted) — Round Flow cassettes with sensing panel or compact cassettes (600 x 600mm fully flat)
  • Floor standing (wall concealed — VRV option only) — concealed wall installation with high level supply (via ducting) and low-level return

Residential solutions include the ability to integrate into home automation systems through MODBUS or KNX gateways. Daikin has different Wi-Fi solutions that are suitable for single, multi-split and VRV systems (D-mobile and Daikin Airbase App).

For large residential applications with multiple systems, Daikin can offer a central controller (ITM) for home automation.
