With the expanding demand for BREEAM/LEED certification for buildings, as well as urbanization pushing cities to grow upwards into the sky, with high-rise buildings, climate control market leader Daikin has just released a major upgrade of their water cooled VRV series, the VRV IV W ‘+’series.
Vienna, December 15th 2017 – According to the company, the redesigned unit delivers enhanced solutions that use lower refrigerant levels in line with EN378 regulations and combined with increased energy efficiency. All this has been achieved while retaining Daikin’s market-leading features, such as being the most compact unit in the market, its geothermal operation, variable refrigerant temperature and the unit’s 2-stage heat recovery operation.
The ‘+’ series offers also a greater range of capabilities, with up to 14HP (40 kW cooling capacity) in single modules and up to 42HP (120 kW cooling capacity) in multi-combinations.
Higher ROI for building-owners
Research shows that the most important elements for building-owners are improved energy efficiency, optimal comfort and absolute reliability, since these all lead to a higher return on investment.
Daikin has redesigned the VRV product, using materials and manufacturing processes that have pushed the COP of their VRV series to 6.50, which is currently the highest on the market. Having a heat exchanger twice as big as the current model is one of the contributing factors to achieving this high efficiency.
In addition, the unit also ensures that the water loop runs to maximum efficiency, as the variable water flow controls the inverter-driven water pump. This improved level of energy efficiency enhances cost-savings in both heating and cooling, as well as further reducing the unit’s environmental impact.
But efficiency isn’t everything. The system has also to deliver optimal comfort for users, often in a multi-tenant environment. This is achieved by connecting the VRV to the latest Daikin Emura and other residential indoor units, hot water hydro boxes, air curtains and ventilation to ensure that users can enjoy draft-free comfort. All this is orchestrated through state-of-the-art web-based controllers.
There are hidden cost-savings as well. Daikin’s unique zero heat dissipation technology allows the system to be kept at a constant temperature without the need for an external cooling source. Combine this with the most compact unit on the market with a 0.5 m2 footprint and it is possible to have smaller technical rooms that no longer need to be cooled or ventilated. In addition, the heat dissipation technology extends the lifetime of critical parts, resulting in trouble-free operation.
Easier maintenance by design
The improvements in design, materials and manufacturing, together with the heat dissipation technology, and enhanced controls all increase reliability and by doing so also reduce maintenance costs.
The VRV IV W +series delivers a number of added-benefits for installers too, ease of use is one of the factors taken into account during the redesign process. Simple-to-remove side and front panels mean not having to remove the refrigerant piping, a rotating switch box and all connections located at the top of the unit allow easier access to all of the major components, making installation, customization and routine maintenance easier and thus less expensive.
To complete the VRV IV W +series, Daikin has a team of experts working with the consultants and installers to ensure that the entire system meets the demanding requirements of building-owners and that the connected water loops are designed in the most efficient way.
