Abstract

A plate-finned coil unit diverges upwardly from the drain pan at an angle of less than 45* in the direction of the airflow. The lower end of the coil terminates in the pan in close spaced relation to an end wall thereof. The pan has a top wall extending from that end wall toward the lower end of the coil. This arrangement provides a sump for the collection of condensate from the coil when the fan coil unit is installed in either the vertical or horizontal position.

HEAT EXCHANGER WI'II'I IMPROVED CONDENSATE DISPOSAL ARRANGEMENT BACKGROUND OF THE INVENTION Fan coil units are used as evaporators in air conditioning systems, especially in domestic installations for dispensing chilled air into room areas. Generally. fan coil units are installed in horizontal position. Such units include a coil positioned in a sheet metal cabinet which also contains a blower or the like for creating an airflow through the coil which is supplied with refrigerant or chilled water. A drain pan is arranged below the coil to collect condensation therefrom.
in some instances, it is desirable to install the fan coil unit in vertical position to better provide for the connection of ductwork to the unit. At present, it is the custom to manufacture and stock the units in two types, one for horizontal mounting and the other for vertical mounting. In lieu of stocking two types of complete fan coil units, two different types of drain pans may be produced for assembly into the units on order to provide a desired type of unit.
SUMMARY OF THE INVENTION direction of the airflow from the fan. The lower end of the coil terminates adjacent one end of the pan which is formed with a top wall extending from that end toward the pan whereby the unit, including the pan, is installed in vertical position. A sump is provided for collecting the condensation from the coil.
' BRIEF DESCRIPTION OF THE DRAWINCifi FIG. ii is a view illustrating the fan coil unit in horizontal position with a sidewall of the cabinet and the drain pan removed;
H6. 2 is a sectional view taken on line li-li of FIG. I; and
FIG. 3 is a view similar to FIG. 1 illustrating the unit in vertical position.
DESCRIPTION OF THE PREFERRED EMBODIMENT The unit comprises an open-ended cabinet having a bottom wall 10, sidewalls 11, and a top wall 12. Conventionally, insu lating material 13 is attached to the inner surfaces of the cabinet walls. A motor-driven blower fan 15 is mounted in one end of the cabinet and is effective to create an airflow in a direction lengthwise through the cabinet.
A fan coil unit 1'7 is mounted in the cabinet intermediate the fan 15 and the opposite end of the cabinet. The coil unit con sists of a multiplicity of tubes extending transversely of the cabinet and connected at their ends by headers 21. A series of thin metallic plates 23 are apertured for mounting on the tubes 20 to effectively increase the heat transfer. The coil unit 17 is supported in the cabinet by brackets 2"! and inclines up wardly from a drain pan mounted in the cabinet contiguous to the bottom wall it). The inclination of the coil unit 1'? is less than 45 to the cabinet bottom wall 10. This inclination of the coil unit is advantageous in that the height of the unit, when mounted horizontally, is minimized which allows installation of the unit in sofi'it areas over living spaces with no additional overall height in single or multiple-story buildings. Another advantage in mounting the coil unit ii? at an angle of less than 45 to the cabinet wall lit) is that when the unit is mounted in vertical position as shown in FIG. 3, the moisture will gravitate down the tin plates 23 without dripping off the unit, and the moisture will be discharged into the drain pan 30.
The lower end of the fan coil unit terminates in the drain pan .30 adjacent the end wall 33 of the pan. The pan is also formed with atop wall 35 which extends from the end wall 33 toward the lower end of the coil unit 1'7. (See FIG. 11.) With this arrangement, when the unit is mounted vertically as in FIG. 3. the top wall at then in vertical position forms in conjunction with the end wall Lid, and contiguous portion of the bottom wall 3'7 of the pan, a sump for the collection of condensate from the coil unit. As shown in FlCi. ll, this sump por tion of the pan is formed with a primary drainage outlet located in proximity to the end wall 33 and the bottom wall 3'7. The pen is also formed with a secondary drainage outlet ill. The drainage outlets till, all are formed in a sidewall d3 of the pan.
The secondary outlet at is located in spaced relation to the end wall 33 and in proximity to the inner edge of the top wall 35. Accordingly, the drainage outlet dll is located above the outlet as with the unit disposed horizontally as in Fit}. 1 and also above the drainage outlet ill when the unit is installed in vertical position (FIG. Ii). The outlets to, il are connected to a suitable drain and the outlet ll is connected in such manner that any drainage from it is visible and serves as an indication that the primary drain d0 has become plugged. This arrange ment is of importance in view of the fact that these fan coil units are often mounted in ceiling structures in homes, and it is accordingly important that the sump portion of the pan does not overflow.
