Description

Air-conditioning condensate discharge device driven by air pressure

technical field

The invention relates to the field of air-conditioning and refrigeration, in particular to an air-pressure-driven air-conditioning condensate discharge device.

Background technique

During the refrigeration process of the air conditioner, a large amount of condensed water will be formed on the surface of its refrigeration components due to the condensation of water vapor in the air. This condensed water is easily produced at the surface cooler of the air handling unit or at the end of the air conditioner (such as a wet fan coil unit). The air handling unit and the air conditioner end generate condensed water to dry the fresh air and eliminate the indoor humidity load respectively. When the outdoor air and the surface cooler of the air handling unit perform heat exchange to cool the dehumidified air, because the wall temperature of the surface cooler is lower than the dew point temperature of the outdoor air, the water vapor contained in the outdoor air will precipitate on the wall of the surface cooler and condense. When the dew increases to a certain extent, it will slide down to the condensate pan under the surface cooler, thus forming condensate. Connect the condensate pipe to the condensate pan to drain the condensate to a suitable place nearby. However, this condensate can cause various problems if it is not handled properly during the discharge process.

At present, the condensed water of household air conditioners is often dripped directly or discharged into the drain pipe of the building body. Direct dripping will cause damage to the ancillary facilities of the building and affect safety. However, the scheme of draining into the drain pipe of the building body will cause construction difficulties and increase costs. In some occasions where the building drain pipes have been installed, the drain pipes cannot be connected with the building drain pipes when the air conditioner is installed, or such connection requires a lot of manpower and cost.
