The condensed water heating vaporization evaporation of adopting, take away water vapour if only depend on heated gas to rise naturally, evaporation capacity is little, and the thermal source that in air-conditioning unit inside, increases newly, can cause the environment for use temperature of compressor to raise, the condensation temperature of air-conditioning unit raises, and influences the service life of air-conditioning unit.For this reason, the high-temperature water vapor that needs as soon as possible evaporation to be produced is taken the air-conditioning unit out of, adopts the flexible pipe water conservancy diversion, and the method for negative pressure steam discharge realizes this process.Mainly be with the high temperature resistant 150 ℃ flexible pipe of embedded steel wire water vapour to be imported to the condensation fan front end, by insulation F level (200 ℃ of heatproofs), the negative pressure that is produced during the blower fan air draught work of protection IP54 (anti-dabbling) is taken the air-conditioning unit out of.
Air conditioner is in the work of dewatering; if the fault of water scavenging system parts; air conditioner needs fault alarm and maintenance in time; for this reason; use PLC, protection contactor, 3 fluid level controllers to come system is controlled and protects; in case break down, the air-conditioning unit can quit work automatically and show failure cause.If can not carry out troubleshooting timely, can adopt condensed water nature exhaust method, discharge unit by drainpipe, do not influence user's use.
In electric control system, increase by 1 electrothermal tube that dewaters, 1 elevator pump, 13 fluid level controller and 1 motor counter-rotating contactor and 2 auxiliary reclays are incorporated into these devices in the control system.
The concrete grammar of realizing no aquation rises to condensed water in the storage water tank by elevator pump exactly, 3 fluid level controllers in the water tank are controlled the electrothermal tube starting and stopping that dewater according to the actual conditions of water level, evaporation condensed water, concrete action is as follows: when water level is higher than meta, the mid-position contact closure, because this moment, the next contact can not be closed, so normally-closed contact closure of normally closed relay, the electrothermal tube that dewaters is started working simultaneously by the self-locking of motor counter-rotating contactor auxiliary contact, condensate evaporation is discharged, and water level reduces gradually.When water level is lower than when the next, the next closing of contact, the normally closed relay contact disconnects, and the electrothermal tube that dewaters quits work.If the water yield of condensation is greater than the water yield or the electrothermal tube fault that dewaters of evaporation; the electrothermal tube work even dewater; water level also can constantly raise; adopt defencive function for this reason, promptly be higher than when upper the upper closing of contact when water level; normally opened relay conducting and self-locking; the high-low level that causes transshipping changes, and alarm signal output is reminded the customer inspection system and removed condensed water.
Control function by above has realized no aquation, has removed from and has handled the loaded down with trivial details of condensed water, further improves automaticity, brings safe and convenient to production.And the utility model needn't must be carried out corresponding civil engineering conveyance system as more external schemes ground on the scene boiling water groove before air-conditioning is installed, and the technical program can be done some transformation, use the existing bridge crane air conditioning of having used easily.
