AI Technical Summary

Technical Problem

Existing wall-mounted air handling units are prone to water drift during condensate discharge, which can lead to unit leakage, affect performance, and potentially cause property damage.

Method used

The design incorporates a combination of an integral hardened water tray-type foamed bottom panel, a hanging sheet metal base, a foamed box panel, an external filter assembly, and a fan motor assembly. This forms an integral water tray, which collects and discharges condensate throughout the entire area via partitioned small water trays and drain pipes. Multiple layers of protection are provided by splash guards and wind deflectors.

Benefits of technology

It effectively solved the problem of condensate leakage, improved the unit's corrosion resistance and service life, and enhanced the efficiency and stability of air handling.

Abstract

This invention relates to the technical field of air handling units, and discloses a corrosion-resistant, leak-proof, and condensation-proof dry-type suspended air handling unit, comprising an integrally hardened water tray-type foamed bottom panel, a suspended sheet metal base, a foamed housing panel, an external filter assembly, a heat exchanger, and a fan motor assembly. The integrally hardened water tray-type foamed bottom panel is an integrated structure with polyurethane foam material filling the space between the inner and outer panels. Its inner panel forms an integral water tray with drainage function. The suspended sheet metal base is fixedly connected to the integrally hardened water tray-type foamed bottom panel and provides support. This invention combines the traditional panel and water tray concept. The inner panel of the integrally hardened water tray-type foamed bottom panel forms an integral water tray, expanding the water tray area to the entire bottom panel, enabling the collection of condensate in the space over a larger area, thus solving the leakage problem at its source. The integrated foamed water collection surface is smooth and flat, without local depressions or water accumulation, ensuring smooth drainage of condensate.
