基于調試數據對PCR實驗室通風空調系統的思考
Consideration of ventilation and air conditioning system in PCR laboratory based on commissioning data
摘要：
以某醫院PCR實驗室為例，剖析調試過程中出現的問題。通過現場調研，對影響壓力及壓力梯度的關鍵參數進行了檢測，包括圍護結構的嚴密性、風機性能與系統風量、送（排）風口風量、通風系統的嚴密性。檢測結果發現，建筑圍護結構的氣密性是形成壓力梯度的前提條件，運行調試應在圍護結構完成密封的條件下進行。在此基礎上，還需要將通風空調系統調試至設計工況，才能保證各區域之間壓力梯度的實現?；谡{試數據，總結了設計通風空調系統應注意的事項。
Abstract：
This paper takes the PCR laboratory of a hospital as an example to analyse the problems that occur during the commissioning process. Through on-site investigation, the key factors affecting the pressure and pressure gradient are tested, including the tightness of the envelope, fan performance and system air volume, the air volume of air supply (exhaust) outlets, and the air leakage rate of the ventilation system. The test results show that the tightness of the building envelope is a prerequisite for the formation of pressure gradient, and the operation and commissioning should be carried out under the condition that the envelope is sealed. On this basis, it is also necessary to adjust the ventilation and air conditioning system to the design conditions to ensure the realization of the pressure gradient between the regions. Finally, based on the commissioning data, the problems deserving to be noticed in the design of the ventilation and air conditioning system are summarized.
