But why was this system chosen?Hydronic VRF systems are a perfect, unique solution, which combines the power of a VRF system with domestic hot water.Unlike other systems, the R2 system enables simultaneous heating and cooling with only two pipes. The thermal energy that is collected during the cooling of the environment goes to heat another environment. This in addition to being a very efficient solution, is handy if some want to heat the room, and some want to cool it.At first glance the system has a number of benefits.Unlike other systems, which use 3 pipes, the R2 system uses only two pipes, which results in: less pipe installation, less work; less risk in gas leakage; higher flexibility.Given these benefits, UNI-KLIMA engineers decide that it is the perfect solution for TES.11 outdoor units were installed in the building, heat pump Heat Recovery R2, PURY-P; and 7 heat pump units Y, PUHY-P.On the other hand, as indoor units would be chosen PEFY-P duct type, units that have visible only the air blowing grilles. The units are very quiet during operation, a condition which was very important for investors considering that the facility would serve as a school.In addition, 30 Lossnay LGH-RVX units, ventilation systems have been installed in the facility to help increase air quality.In order to have a healthier environment for students and employees, the TES requires the best possible air quality, a factor which has been proven to be the parameter and the main factor in comfort, productivity and fatigue.To complete the system, in every aspect, the WRX-HR-F0302 air treatment unit has been installed.In conclusion, the Hydronic VRF system mounted on the TES, is the latest all-inclusive technology system. Clean air, air conditioning on request and demand, ventilation system to increase air quality and air treatment equipment, not forgetting the hot sanitary water throughout the building, all in a single system
