Application of VRF systems in the buildings of the hotels have the following advantages:
- High energetic efficiency
- Simple maintenance
- Advanced systems of dispatching

LG Electronics specialists with the help of EnergyPro TM software, elaborated by American company EnergySoft, and which let make calculation of cost efficiency for the concrete type of the building, made an analysis of work of VRF air-conditioning systems in the building of the hotel:
• Square of the building: Stotal = 12 500 m2
• Number of floors: 6
• Total number of maintained zones including the bed bank and subsidiary buildings of the hotel: 145
• Infiltration: 0
• Location: USA, Atlanta, Geogria
• Electricity rate for corporate bodies of the USA in recalculation into rubles is: 2,7 rubles per kWt/h
• Maintenance mode: year-round
• Tested systems: LG Multi V Heat Recovery
It is seen from the schedule that the usage of VRF-system with recuperation of heat exceeds half as much as analogs in some cases. At the calculation the cost of electricity, equipment maintenance and number of workforce attracted to the maintenance of airconditioners have been considered.
