西安西藏大廈空調系統精細化設計及節能運行
Fine design and energy efficient operation of air conditioning system in
摘要：
介紹了該項目空調系統精細化設計的主要特點。通過全年動態負荷和技術經濟比較，確定冷熱源設備選型，確保運行節能，穩定可靠。利用餐廳包間新風和排風系統，通過調節新風溫度，消除內區包間余熱，解決采用兩管制的不足問題。通過氣流模擬和房間使用特點和要求，分別確定多功能廳和餐廳包間的風口形式和位置，確保使用舒適。經過3年的數據統計，該項目非供暖能耗指標和供暖能耗指標均滿足約束值，2019和2020年非供暖能耗指標均基本達到引導值。
Abstract：
The key points of fine design and operation of the air conditioning system of the project are presented. Through annual dynamic load and technical and economic comparison, the type of cold and heat source equipment is determined to ensure that the system is energy-saving, stable and reliable. The outdoor air and exhaust air system in the restaurant private room is used to eliminate the waste heat in inner zone, and adjust the outdoor air temperature to solve the shortcomings of two pipes system. With airflow simulation and considering room characteristics and requirements, the air outlet form and position of multi-functional hall and dining room respectively are determined to ensure comfortable use. After three years of data statistics, the projects non-heating energy consumption indicators and heating energy consumption indicators both meet the constraint values, and the non-heating energy consumption indicators in 2019 and 2020 reach the guide value.
