CLIVET’s range of VRF CVT8 heat pump outdoor units is the ideal solution for large surface areas, boasting the world’s highest capacity as a single module, up to 90 kW, and which can be combined with up to 3 units. Easy to install and maintain, the CVT8 units operate steadily with outdoor temperatures from -15°C to 55°C in cooling mode and -30°C to 30°C in heating mode, and have 15 silent modes to fulfil all demands for acoustic comfort. They also have 3 features that are unique on the market: electronic components protected via Safebox, Multisensor control technology and the revolutionary EasyCom BUS that greatly simplifies installation.
The VRF MSAN8 range, on the other hand, favours the compact design of the horizontal discharge without forsaking the concept of modularity: with its capacity of up to 246 kW, installations with an outdoor unit on the floor can be realised, so as to increase performance, simplify maintenance operations and reduce the amount of refrigerant. Lastly, the use of R-32 refrigerant with a low GWP makes the VRF MSAN8-Y line of heat pump outdoor units among the most environmentally friendly and safe on the market, while maintaining its unique range of application, reliability, comfort and easy-to-install features.
Packaged systems
If you are looking for a system that is quick to install and extremely economical, and which also ensures ideal air conditioning and optimum air quality in shopping centres, railway stations, airports, restaurants, cinemas and industrial buildings, the perfect solution is called Rooftop Package. This type of system features a range of packaged units (inverter or multiscroll heat pumps, Rooftop air-to-air or water-to-air) capable of producing locally the thermal and cooling energy required to air-condition the various rooms only when and where it is needed. Each single area is served independently, through a distribution system consisting of ducting and distribution terminals, with the heat pumps adapting their operation to the actual heat load and fresh air required, thereby ensuring the best living comfort and achieving very high seasonal efficiencies.
The second type of systems for air-conditioning large areas are hydronic systems. As the name suggests, water plays a key role in these solutions. The thermal and cooling energy to the indoor units, which are required for heating or cooling, is distributed through water piping in which water circulates. The heat generator par excellence in these systems is a heat pump, which, as we all know, provides very high energy efficiency. On the other hand, air renewal is usually handled by an air handling unit supplied by a chiller.
Compared to other solutions, hydronic systems are the most popular and widespread for air conditioning and, as a result, are easy to design and install and require little maintenance.
The advantages of this solution are obvious:
- System flexibility, as the hydronic system integrates perfectly with other systems (radiant, induction, chilled beams)
- High energy savings, due to free-cooling of air handling units and chillers
- Safety, of having an environmentally friendly heat transfer fluid such as water.
VRF systems
Among the most popular air conditioning solutions in the commercial & industrial sector, VRF – Variable Refrigerant Flow systems ensure high efficiency in both winter and summer and differ from hydronic systems because refrigerant fluid instead of water flows through the distribution pipes. This type of system consists of an outdoor unit (considered the true heart of the system), copper piping in which the refrigerant fluid flows, and a range of indoor units, fitted with electronic expansion valves, which ensure a larger extension of the system compared to a residential Split system.
