Background

At present, condensed water generated after heat exchange of a part of marine combined air conditioners, cabinet air conditioners, fan coils, a part of armed cabinets and other devices is collected by a sewage well or an air conditioner condensed water collecting device which flows to the bottom of a cabin under the action of gravity after being combined nearby by a condensed water pipeline, and then is uniformly discharged to the outside of a ship board through a discharge pump; the rest air conditioners are directly discharged to a deck drainage port of the cabin under the influence of arrangement positions, pipeline design and the like. For the air conditioner condensed water collecting and discharging system which automatically flows under the action of gravity, the phenomena of slow discharge and congestion of condensed water, even the phenomenon that the condensed water is reversed out from a water collecting disc to immerse a cabin and the like often occur. Such a phenomenon occurs, and there are mainly the following problems:

1. in the aspect of comprehensive arrangement, due to the arrangement relationship of the cabins, an oil cabin, a water cabin and an important armed cabin are arranged below the positions of part of the air conditioners, so that a water condensation pipe of the air conditioners cannot directly penetrate through a water condensation pipeline downwards and must transversely or longitudinally extend to bypass the oil cabin, the water cabin and the important armed cabin below; the length of the water condensation pipeline is increased, the water condensation pipeline is easy to have a local climbing phenomenon, and the water condensation pipelines are easy to have the phenomena of slow discharge, congestion and water return under the influence of ship swing; 2. in the aspect of pipeline arrangement, due to the requirement of system design and arrangement, the air conditioner condensate pipeline is combined and discharged to a specified air conditioner condensate collecting and discharging device or a bilge well according to the overall design requirement, so that the condensate pipeline has an arrangement mode that the condensate pipeline extends from a port to a starboard and extends from a stern to a bow in order to combine the pipelines. Due to the characteristics of low stern part, high bow part and high midship and low broadside, when the water condensation pipe adopts the arrangement mode, the condensed water of the air conditioner has the phenomenon of local climbing, and the phenomena of slow discharge, congestion and water reversing are easy to occur;

3. in the aspect of equipment design, a condensation water accumulation disc of a combined air conditioner used on a ship is designed at an air suction opening of a fan, so that the combined air conditioner has overlarge negative pressure and very slow condensation water discharge in the operation process, and a water return phenomenon occurs when the combined air conditioner generates excessive condensation water; the special air conditioner water condensation and accumulation disc is designed at the air outlet of the fan, so that water in the special air conditioner water condensation disc and air enter the water condensation pipeline system together, the pressure of the water condensation pipeline system is increased, and further, the problem that partial condensed water of the air conditioner cannot be smoothly discharged is caused, and even a water return phenomenon occurs in a serious person; the small-size air conditioner is because by the restriction of body size, and the design height of ponding dish is lower, and the water storage capacity is limited, if the inflow is greater than displacement all the time, will certainly let the water of congealing spill over from the ponding dish, the water-back phenomenon appears.
