1, the cooling tower to meet the following requirements:
① cooling tower thermal performance requirements;
② cooling tower noise, floating water, fire, weight, and other requirements;
③ cost, power requirements;
④ mounting surface, height, water quality requirements;
⑤ other special requirements. Before thermodynamic calculation respond thermal performance curve to verify suppliers offer, verify that it is correct or not, because it may be false or erroneous. Users can verify yourself, or commission personnel inspection. If necessary, the user can ask the supplier of cooling tower packing mass transfer coefficient ka (or βxv), cooling the number N, into the tower air traffic G. For suppliers to provide ka, Ω, G, should also verify its correct or not. These numbers can be verified using the thermal performance of the cooling tower from the other.
2, pay attention to several issues selection may ask suppliers:
① to be selected to catch the cooling tower packing volume, height, width, diameter deep is how much?
② form filler piece from the filler area ratio is the number?
. ③ according to the national standard GB / T7190-1-2008 Appendix A: calculated thermal performance test methods can be calculated. Its cooling water is the number?
④ cooling tower out of the pipe diameter, the corresponding flow rate is how much?
⑤ catchment disk storage capacity is how much?
⑥ into a hydraulic tower How much?
⑦ air inlet height?
Measured report ⑧ cooling tower heat, noise has?
3, the user should clear their conditions, such as the following:
① space cooling tower installation site, the minimum distance between the tower and the tower, the tower and other buildings in the minimum spacing?
② circulating cooling water system has no separate cold pool? What form?
③ circulating cooling water of quality is too bad, for example, a gas washing water gas station, the water contains more tar, ash, coal, etc., should not be chosen PVC film-type filler.
④ whether the explosion, lightning, earthquake, fire-retardant requirements?
⑤ wind load, snow load is how much? Foundation bearing capacity much?
⑥ into the tower design air wet bulb temperature or the presence of small hot and humid climatic zone air reflow interference? ⑦ guaranteed rate of cooling tower water temperature presence or absence of more stringent requirements?
4, the technical requirements of the cooling tower, cooling tower according to national standards have the following main elements: thermal performance; noise; floating in water rates; glass steel members; fillers.
5, penalty claims and delay in delivery of both buyers and sellers can decide responsibilities.
