Daikin launches LT Hydrobox for VRV

Daikin has launched a Low Temperature (LT) Hydrobox for the latest generation of the VRV heat pump, which delivers highly efficient space heating and cooling.

The LT hydrobox indoor unit is designed specifically to work with VRV IV, the latest generation VRV and the only weather-dependent VRV system on the market today.
VRV IV already delivers highly efficient climate control. Now, with the launch of the new LT Hydrobox, the system provides highly efficient space heating and cooling - even for areas with high ceilings and glass facades, such as reception areas.
The LT Hydrobox delivers water from 5°C to 45°C without the need for a back-up electric heater, for use in underfloor heating and cooling, air handling units and low temperature radiators, making it ideal for both new build and refurbishment projects. It has a super-wide operating range for heating and cooling, from -20°C to +43°C ambient outdoor temperature, making it suitable for all European countries.
The wall hung hydrobox is stylish and compact, with front access and reduced clearances making it easier to install, commission and maintain. System design is faster and installation is simplified as all the water-side components are fully integrated in the hydrobox, which also gives direct control over the hot water temperature.
VRV IV – setting the innovation standard
Daikin’s VRV IV heat pump achieves a new benchmark for seasonal efficiency, featuring major enhancements to the already industry-leading VRV solution. It has three revolutionary innovations: variable refrigerant temperature, continuous heating during defrost and the VRV configurator for simplified commissioning and servicing.
Variable refrigerant temperature technology allows installers to customise the system using a choice of presets. In automatic mode, the system is configured for high efficiency levels throughout the year, while allowing rapid response on the hottest days, thereby ensuring comfort at all times. This technology is capable of delivering a 28% increase in seasonal efficiency, because the system continually adjusts the refrigerant temperature according to the total required capacity and weather conditions. This makes VRV IV the first weather-dependent VRV in the world.
Continuous heating during defrost sets a new standard in comfort, making VRV IV one of the best renewable heating systems available. Continuous heating finally overcomes any perceived disadvantages of specifying a heat pump because the heat pump continues to provide continuous comfort, even when in defrost mode.
The new VRV configurator completes the trio of innovations, offering an advanced software solution that simplifies commissioning and servicing. The software allows the remote configuration of settings, which can be used at multiple sites, so less time is required on the roof, commissioning the outdoor units. Ongoing maintenance is easier too, thanks to a graphical interface that allows engineers to evaluate operational data and errors.
