PACKAGED System. PACKAGED System Packaged air conditioning for retail, service and high attendance applications

Transcription

1 System System Packaged air conditioning for retail, service and high attendance applications System is the quickest and most competitive solution for climate control in large buildings. The cooling or thermal energy needed for climate control is produced locally only when required and sent to the serviced areas via a suitable air distribution and diffusion system, consisting of ducts and diffusion terminals (outlets, anemostats, nozzles, etc.). These packaged units are highly efficient because they do not use intermediate fluids. They offer a very high performance thanks to systems such as active thermodynamic recovery. 148

3 PAN-XHE Make-up unit, full fresh air With return/exhaust and thermodynamic heat recovery 4Reversible heat pump Indoor and outdoor installation Air flow rate from 1250 to 4444 l/s (from 4500 to m 3 /h) ZEPHIR 2 ZEPHIR 2 is the innovative all fresh air conditioning monobloc heat pump that executes the recovery of air with a high efficiency, thanks to the integrated energy recovery of the active thermodynamic type and the exclusive construction and functional features. It is a high-performance cooling and heating energy generator that uses the expelled energy as a source and does not have the high load losses of a traditional static recoverer. It is able to compensate the fresh air load and even contribute to the air-conditioning of the served area during most part of its operation. The reduced consumption at partial load of the refrigeration circuit, the electronic expansion valve, the electronic control plug-fans and the wide range of accessories allow to highlight the entire system in the different situations of use. Zephir 2 is available in two different configurations: 4 ZEPHIR 2 REOVERY It is able to do away with a good part of the air renewal load, even in the most demanding operating conditions, entrusting the remaining part to the built-in climate control system. During the remaining operating period, it is able to generate, at levels of high efficiency, further capacity to be introduced into the ambient. 4 ZEPHIR 2 ENERGY This is the version with the biggest capacity, able to cancel out the air renewal load for good part of the year. During the remaining operating period, the biggest available capacity leads to a further reduction in the intervention of the built-in climate control system. The ENERGY version therefore increases the advantages of the REOVERY version. functions and features AIR R-410A F EEV AF Active Thermodynamic Heat Recovery Heating-ooling Air cooled Roof Top Refrig.
