i-WHISPER ENTHALPY 0182 – 0753
Reversible air cooled high efficiency all in one rooftop units, with enthalpy recovery and inverter scroll compressor Total cooling capacity 87,0 – 338 kW
High efficiency and precision autonomous and reversible air to air Rooftop unit for the complete thermohygrometric air treatment and the recovery of the rejected heat for the air renewal. The filtration, ventilation and air renewal are provided by a packaged solution that perfectly suits in applications where, in addition to load variability, there are high latent loads and the need to guarantee the best conditions for the occupants. Both winter and summer operation, double cooling circuit, inverter driven scroll compressor with R410A refrigerant, electronic thermostatic valve. External exchangers with finned packaged coils with thermodinamic effect on the exhaust air, external axial fans and cutting phase condensing control device. Air treatment section with plug fan, finned packaged exchangers, motorized external air, mixing and expulsion dampers and enthalpic heat recovery. Precision also at low loads and fine control of the temperature thanks to the control realized on the supply air.
- B – Basic
- THERMOHYGROMETRIC MANAGEMENT ON THE SUPPLY AIRFLOW
The supply temperature control provides the best ambient conditions in terms of temperature and humidity, also with high percentage of fresh air.
- EXTREME ADAPTABILITY TO THE REQUIRED LOAD
The unit perfectly follows the thermal demand of the ambient. The continuous modulation of the capacity, thank to the use of the inverter tecnology in the refrigerant circuit, allows to obtain better performances than the traditional step regulation and to obtain significant benefits in terms of comfort for the ambient.
- HIGH COMFORT
The unit suits in applications that require precise and continuous regulation of the ambient conditions, also during hard working conditions, like the ones with high fresh air percentage( up to 80%).
- ROTARY-TYPE ENTHALPY RECOVERY
The exclusive enthalpic rotary heat recovery allows to recover from the exhaust air both sensible and latent heat, both in winter and summer operation. The recovery of the latent heat improves the dehumidification capability of the unit in summer and the humidification in winter, with a very high efficiency ratio.
- PLUG-FAN VENTILATION
The supply and return plug fans combine the high efficiency of the ventilation section with an easy and fast installation of the unit, both electrical and aeraulic.
- CO2 control sensor for air quality
- High efficiency filters: electronic or rigid pocket F7
- Set-up for remote connectivity with ModBus/Echelon protocol cards
- Remote control keyboard (distance to 200m and to 500m)
The AIR3000 TE controller offers advanced functions and algorithms. It is made up by two control boards, dedicated to the air side and the refrigerant side respectively. The keypad features functional controls and a complete LCD display that allows for the monitoring and intervention on the unit by means of a multi-level menu with selectable user´s language. The step proportional capacity adjustment is based on the return temperature; proportional-integral management can also be set. Its functions include the adjustment of the ambient humidity, the thermal or enthalpic (optional) free-cooling and supply temperature limitation. Defrosting is based on a self-adaptive propriety logic with monitoring of several operating and environmental parameters. The management of the ventilation can be realized with constant air flow regulation (optional): as pressure drop varies, the fans change speed so as to maintain the flow-rate at the designed value for the system, regardless of filter clogging. The controller allows to integrate and automatically manage different optional thermal resources (hot water coil, electrical heater and gas thermal module), hot gas post-heating (optional) and the fresh air percentage (optional with CO2 sensor or remote signal 4-20 mA). The presence of the programmable timer allows the user to create an operating profile containing up to 4 typical days and 10 time bands. The diagnostics comprises a complete alarm management system, including ‘black box’ (via PC) functions and an alarm log list (via display or also a PC) for optimized analysis of the unit performance. Supervision can be easily developed via proprietary devices or via third party systems by means of the most common protocols as ModBus, Bacnet, Bacnet-over-IP, Echelon LonWorks protocols. Compatibility with the remote keyboard managing up to 10 units.
