The VRF system is the ideal solution to combine environmental comfort, energy saving and CO2 emissions reduction with a single air conditioning system both in summer and winter.The heat pumps technology is implemented with indoor units in order to produce hot water for sanitary use (HWS) and for heating with radiant panels (ATW), perfectly integrated with the insertion of solar panels in the system. Plants with electric heat pump system can operate throughout the year, as they are disconnected from any legislative constraint. The spring and autumn air conditioning are an additional comfort in this type of plant. The VRF systems indoor units slightly cool and dehumidify the environments during the spring, while cooling and dehumidifying in the summer, by transferring the energy prevously stolen from them by HWS and ATW indoor units, and they gently heat the environments in the cooler hours during the fall. The ATW indoor units provide hot water for heating in the winter through radiant panels, and provide a possible pool with hot water in the summer, keeping its temperature. In the summer, you can send cold water to the radiant panels in order to obtain a floor cooling.The Airclima design office is ready to provide both its private and business clients with free consulting services.
