AI Technical Summary

Problems solved by technology

Most importantly, the heat exchanger can move in the direction of air flow, causing impacts on the side walls of the recuperator
Since recuperators are usually made of folded sheet metal where the sheet metal sidewalls are welded to each other, weld damage can occur and cause tightness issues

Embodiment Construction

[0038] Air handling unit 1 in figure 1 shown above. The air handling unit 1 comprises a housing 3 extending along a longitudinal axis X. As shown in FIG. The housing 3 is delimited by panels comprising an inlet panel 30 and an outlet panel 32 , each provided with openings 300 and 320 . In this example, the air flow enters the housing 3 along arrow A1 through opening 300 and exits through opening 320 along arrow A2. The air flow circulates in a flow direction corresponding to the longitudinal axis X. The invention is not limited to this type of air path and various other air paths may be used, including dual flow in some air handling units. The housing 3 also comprises longitudinal panels comprising a bottom panel 34 , a rear panel 36 and a top panel 38 extending parallel to the longitudinal axis X. As shown in FIG. The housing 3 also includes a front panel, which is omitted to show the inside of the housing 3 .

[0039] The air handling unit 1 comprises at least one heat ...

Abstract

An air handling unit (1) comprises an enclosure (3) in which air circulates along a flow direction (X), at least one heat exchanger (5) mounted in the enclosure (3), a condensate recuperator (15) placed under the at least one heat exchanger (5), and a support member (13, 19) stationary with respect to the enclosure (3), and which supports the condensate recuperator (15). The air handling unit (1)comprises a stop member (21) attached to the heat exchanger (5), and cooperating with a portion (132) of the support member (13, 19), the heat exchanger (5) is mounted in the recuperator (15), and anensemble formed by the heat exchanger (5) and the recuperator (15) is blocked with respect to the support member (13) longitudinally to the flow direction (X) during transportation by the stop member(21).

Description

technical field [0001] The invention relates to an air handling unit. Background technique [0002] Air handling units are suitable for treating air: filtering, decontaminating, humidifying, drying, heating, cooling, etc. Some air handling units adapted to generate cooled air for air conditioning include heat exchangers, which can cause condensation of moisture in the process air. In air conditioning applications, it is known to place a condensate tray below the heat exchanger to drain the condensate outside the enclosure. These condensate trays cannot be removed or cleaned. Prior art air handling units consist of a recuperator placed below the heat exchanger to reheat the condensed liquid, and a removable tray that is To receive condensate from the recuperator. [0003] A standard air handling unit has a recuperator held by a support member below the recuperator. The heat exchanger is mounted on the recuperator such that the weight of the heat exchanger is borne by the...
