Application of VRF to an ultra-high standard reception project

This paper expounds on the design characteristics of the HVAC system for an ultra-high standard reception project, and presents the optimization of interior design parameters, cold and heat source scheme, system division, calculation and checking calculation, vibration and noise control, reserve and other detailed design from the analysis and implementation of the main design requirements of the project. The application of the scheme of the three-pipe heat recovery high sensible heat variable refrigerant flow (VRF) unit plus the direct expansion constant temperature and humidity outdoor air unit and the floor heating to this project is emphatically presented, which provides a new solution idea and a case for the design of ultra-high standard reception projects and temperature and humidity independent control air conditioning systems.
