New air unit faults winter deactivated new air unit has water in the cooler; located in the basement of the new air unit deactivated after winter cooler fresh air units offer the cracking accident occurred, mainly due to the table in the new air unit has water in the cold. Possible reasons are as follows: There is no open (a) Discharge run cooler fresh air damper unit, so there is no cooler air into the channel, so the water cooler can not be completely emptying inside, resulting in winter outdoor temperatures After reducing the fresh air unit cooler cracking. (B) Because there is standing water in the cold water system piping, the location of new wind generating units were lower than the main pipe system, if the connection line valves closed lax, the water in the cold water supply and return water pipeline begins to slowly seep in cooler, So despite sluicing operations will still lead to the cracking of the accident. The accident may be the two reasons, one cause, so in both areas has been improved, additional lifting DN15 bleed air unit at the highest point of the new supply and return risers fresh air units, air handling units in the new deflated and when you can use a horizontal drain fresh air unit, in particular, can ensure the thoroughness of discharge; and in the fresh air supply and return water on the road of establishing an additional valve unit, completely cut off slow down bleeding problems after discharge. Safe operation of the proposal must set up an effective monitoring device interlock antifreeze controlled fresh air unit design. Fans must first ensure that the rated water flow heater is running, when the water temperature is too low or too small water flow alarm and promptly closed due blower and fresh air unit new wind of the population in prison is not equipped with thermal insulation damper · Full protection measures actually only semi-finished products In the cold winter put into operation no security guarantee and can not "posts."
