Analysis And Discussion On The HVAC Design Of Zhonghao Hotel

This paper gives out principal keys on design optimizing, energy consumption reduction, resources saving and elementary investment reduction for HVAC systems of typical modern hotels.As a case study, data derived from the HVAC systems of Zhonghao Hotel are calculated and analyzed. Three sections, - heating/cooling sources optimization, analysis and calculation of public kitchen ventilation, and analysis and calculation of ventilation for indoor swimming pool -are discussed for the proposal of energy saving and environmental protection.Practical methods on heating/cooling sources selection, which consist of the principles of feasibility, economy, adjustability/maneuverability, security and environmental friendliness, are introduced to avoid over-sizing HVAC equipments. Calculation of the HVAC systems of Zhonghao Hotel shows that analysis on annual energy consumption is essential to optimize the potential plans. Economy analysis is the most concerned one of the five principles above by the owners of the realties, thus the plan for HVAC systems with the character of the lowest annual energy consumption usually wins.Ventilation systems of public kitchen should be paid great concern. People nowadays know very much about the pollution in public kitchen and the impact to human health. This paper tries to figure out the most significant problems which often occur in the design of kitchen ventilating. Here list several rules followed when designing: 1. Return air duct system should not be applied to public kitchen ventilating. 2. Air currents should be organized properly. 3. Exhaust volume should match the requirement of the wind speed around the slot inlet of the hoods.HVAC systems for indoor swimming pool have unique characters according to normal ventilating systems. This paper gives a suggestion after analyzing misconceptions in several other projects that the most crucial point of ventilation designing for indoor swimming pool is to prevent condensation on surfaces of building envelopes. The primary focus should be on the initial design of the structure and the HVAC systems. The most effective way to do so is to analyze the special indoor environment of swimming pools, calculate the proper volume of moisture migration and ventilation, and check carefully the heating/cooling loads. Good air currents organization could also be essentially necessary.Generally, projects with HVAC systems occupy a great part in the overall building market. Energy consumption in Buildings especially by HVAC systems makes a big deal of the payment of electricity and fossil fuels. This paper could be helpful to decrease the energy consumption by. HVAC systems and reduce mistakes of HVAC design of typical modem hotels.
