They should be test at straight duct section with a diameter of at least 4 times as much as that of duct (or size of longer side of rectangular duct) after local resistance, or with a diameter of at least 1.5 times as much as that of duct (or size of longer41、 side of rectangular duct) before local resistance. When conditions are limited, the distance can be shortened and more points be increased. 測定風管內風量的測定：系統總風管和各支管內風量與風壓的測定截面的位置應選擇在氣流均勻出，按氣流方向應選擇在局部阻力之后大于或等于4倍直徑（或矩形風管大邊尺寸），和局部阻力之前大于或等于 1.5 倍直徑（或矩形風管大邊尺寸）的直管段上，當條件受到限制時， 距離可適當縮短，且適當增加測點數量。4.3.2.2 Air vo42、lume test at air intake 風口風量的測定：A. Test wind speed with anemoscope at fixed point near air intake or by revolving at a constant speed. The average value of wind speeds tested at fixed point is the wind speed at the point. 用風速儀在貼近風口處作定點測量或等速回轉法測量風速，取定點法測得的風速取平均值，就為該點的風速。B. The grating or mesh of air 43、outlet contributes to a considerable difference between effective area of outlet and the shell leading to contraction of outgoing air flow, so in calculating air volume at outlet, multiply by 0.71.0 of correction coefficient to make it more accurate. Meanwhile, for air inlet where scope of incoming 44、is small and air flow is relatively even distributed, so the result is mostly accurate only if the test is conducted near the inlet. 在計算風口送風量時，由于風口送風口帶有格柵或網格，其有效面積和外框相差較大，送出氣流為緊縮現象，因此計算面積時應乘以 0.71.0 的修正系數，使計算風量更符合實際，而吸風口，則由于吸氣作用范圍較小，氣流較均勻，只要靠近風口，測量結果一般較正確。C. Allowable deviation between actual and de45、sign air volume of main, trunk and branch ducts should not be larger than 10%.系統總風管、主干風管、支風管各測點實測風量與設計風量的偏差不應大于 10%4.3.2.3 Balance of system air volume 系統風量的平衡：A. Only when air volumes of fan and system (incl. total volume of supply and return air, fresh air volume, primary and secondary return air 46、volume, exhaust air volume, and volume of main, trunk and branch ducts at air intake) reach design requirements can adjust air volume of the whole system to requirements. 在風機風量測定、系統風量的全面測定（包括送、 回風總風量、新風量、一、二次回風量、排風量以及系統中各總、干、支風管風量風口風量）達到設計要求后，即在全系統風量摸底基礎上方可進行系統調整，使之達到系統風量的要求。B. Balance air volume of47、 the system through control valves at shutter, fan and piping of fresh air, primary and secondary wind and air intake. 系統風量的平衡調整，可通過各類調節閥實現，利用新風，一、二次風，風口處的百葉窗、風機及管道各部位的調節閥等進行調節。C. Adjusting method: ratio of equal air flow: start from least favorable circuit (in general the farthest branch system. Su48、ppose the farthest branch system is 1, and the next 2, and the process goes on) According to actual air volume of branch duct, adjust its ratio L1/L2 with control valve to that of design volume L1/L2, i.e. L1/L2L1/L2, and then adjust L3/L4L3/L4, L3/L4L3/L4and finally the first branch duct to make th49、e ratio about 1. (Total actual air volume nearly equals to total design volume).調節方法如下： 流量等比分法：先從系統最不利環路（一般為最遠的分支系統，假設最遠的支系統設為 1，其次為 2，以此類推）開始，根據支管的實測風量利用調節閥將其風量的比值 L1/L2調整到與設計風量 L1/L2 的比值近似相等，即是使 L1/L2L1/L2，再依次調整 L3/L4L3/L4、L3/L4L3/L4最后調整到第一支管的風管段，使之前后比近似為1。(實際總風量近似于設計總風量)D. Adjust section by secti50、on: first of all, adjust air supply duct till the volume is 5%10% larger than design volume, and then adjust branch duct near main duct and end duct to make them close to design volume one by one. Start from least favorable circuit to intermediate branch duct and finally to total air volume of ducts51、 between fan and the first branch duct to make it close to design volume. 逐段調整法：調試方法式從風機開始，將風機送風管先調整到大于設計風量的 5%10%，再調整靠近總管處的支管和最末端的兩支管，使之依次接近設計風量，將不利環路調整平衡后，再調整中間支管，最后調整風機與第一支管間風管的總風量,使之接近設計風量。4.3.2.5 Run test of ventilation and AC system includes air volume and pressure and volume balance of fan, d52、uct and intake. In summer, refrigerating is required after completion (in winter, commission after connection to hot source). Interlocking run test of AC system should last at least 8h and that of fan, duct and fittings etc under zero loads should last at least 2h in a row. 通風空調系統的試運行使系統風機、風管、風口風量風壓53、測定，以及風量平衡 的基礎上，夏季竣工時進行制冷調試（冬季接入熱源再調試），空調系統聯動試運轉時間不少于8h，在無生產負荷下進行風機、風管與附件等全系統的聯動試運轉， 其連續運轉時間不少于2h。4.3.3 As VRV AC system will be commissioned by manufacturer, the commissioning plan will be provided later as a supplement to this plan.
