VRF Low Temperature Domestic Hot Water Unit
– A Comprehensive Range: Hydro Free Hot Water Module (Low Temperature)
Our VRF indoor unit lineup now encompasses the complete range of "Hydro Free" hot water modules. These modules efficiently generate both space heating and domestic hot water, akin to traditional oil or gas boilers. They achieve this by harnessing renewable energy from the outdoor air and converting it into heat.
Air-to-water heat pumps are the driving force behind this process, extracting free energy from the air. This energy proves sufficient to warm homes or villas to a comfortable temperature, even on the chilliest winter days. Remarkably, for each kilowatt of electricity utilized to power the heat pump, it can yield over 5 kilowatts of heating energy. This translates to savings of up to 80% on heating costs when compared to conventional fossil fuel boilers.
The Hitachi VRF Hot Water Module is particularly advantageous for those considering a 3-pipe VRF system (simultaneous cooling and heating type). It efficiently harnesses excess wasted heat, further enhancing its value. Employing cutting-edge technology, it not only delivers exceptional space heating performance but also provides domestic hot water with remarkable efficiency.
– Versatile Low-Temperature Range (45℃)
The Hydro Free hot water module lineup offers three distinct models, with capacities ranging from 100L to 180L, all tailored for low-temperature range operations, specifically designed for space heating. These units are engineered to deliver optimal comfort while boasting a compact and ultra-quiet design that allows for effortless wall mounting.
Installation is simplified through the Plug & Play system, which includes all essential equipment such as a circulator, filter, expansion tank, purges, and manometer. The refrigeration network's adaptability enables seamless integration into a variety of installations, and a single generator can effectively fulfill both cold and hot water requirements.
This versatile solution is particularly well-suited for renovation projects, as it can be seamlessly integrated into existing hydraulic systems, enhancing their efficiency and performance.
– Best option indoor unit for 3-pipe VRF
In summer, when utilizing a Heat Pump or Heat Recovery type VRF system without the Hydro Free unit, all indoor units operate in cooling mode. Consequently, the VRF outdoor unit expends heat energy unnecessarily into the atmosphere. However, with the inclusion of the Hydro Free unit, this wasted heat energy, typically released into the surroundings, is redirected to heat water, offering an efficient solution for your domestic hot water needs.
– Operations: space heating
Hitachi's VRF indoor units equipped with the Hydro Free hot water module are preconfigured for efficient space heating. These systems offer various heating installation configurations, ensuring a comfortable indoor environment throughout the year, even in the most frigid climates:
- Mono-valent System: This design sizes the air-to-water heat pump to fulfill 100% of the heating requirements, even on the coldest days of the year.
- Mono-energy System: The most popular choice, this configuration sizes the air-to-water heat pump to meet 80% of the heating needs during the coldest periods. An auxiliary electric heater (supplied in the field) supplements the additional heating required on colder days. This option strikes an ideal balance between installation costs and long-term energy consumption, a proven favorite in colder regions like Sweden and Norway. Alternating Bi-valent System: Designed for installations with existing boiler-based heating systems, this setup enables the boiler to alternate with the air-to-water heat pump. It's particularly useful when it's necessary to elevate the water temperature supplied to the circuit to higher levels, such as 80℃.
- These diverse configuration types allow for adaptable systems tailored to meet various customer needs, accommodating a wide range of applications, from straightforward setups to comprehensive configurations like radiator heating, floor heating, or a combination of both.
– How is it used?
The module comes equipped with all essential components as standard, including a circulator, filter, expansion tank, purges, and manometer. Begin by connecting the water tank to the Hydro Free unit. For space heating purposes, further connect the water piping to either a radiator or a fan coil unit.
