POMPE DE CALDURA, AER CONDITIONAT, CHILLER
WET ENTHALPY 0102 – 0604
Water cooled rooftop unit for WLHP and WSHP, with enthalpy heat recovery
Total cooling capacity 55,7 – 278 kW
B – Basic
PC – function for constant water flow system
PV – function for variable water flow system
PP – function for disposable water system
- VARIABLE AIRFLOW FOR AIR TREATMENT SECTION
The VAir function allows to change the air flow according to the therma load, providing a significant reduction in terms of electrical consumption for the air treatment fans.
- HIGH ENERGY EFFICIENCY
The use of the R410A, the high energy recovery rate from the exhaust air and the use of intertwined coils provide an high energy efficiency during the working of the unit.
- 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.
- SAFE USE
Refrigerant lines and regulation devices are easily accessible and separated from the air treatment section. Thus meaning a reduction of contamination accidental risk and allowing the valves adjustment while the unit is running.
- Enthalpy free-cooling
- CO2 control sensor for air quality
- Hot gas post heating
- Set-up for remote connectivity with ModBus/Echelon protocol cards
- Remote control keyboard (distance to 200m and to 500m)
- High efficiency filters: electronic or rigid pocket F7
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.
