Abstract

A condenser module configured for use in a condenser is provided including a housing having a first longitudinal side that defines a first air inlet and an opposing second longitudinal side that defines a second air inlet. A heat exchanger assembly is positioned within the housing. The heat exchanger assembly includes at least one heat exchanger coil. A cross-section of the heat exchanger assembly is generally constant between a front side of the housing and an opposite back side of the housing. At least one of the front surface and the back surface is configured to abut an adjacent contact module. A fan assembly includes at least one fan generally aligned with a single heat exchanger coil in the heat exchanger assembly.

First claim

The invention claimed is:

1. A condenser comprising:
a frame;
a plurality of condenser modules stacked within the frame, the plurality of condenser modules including a first condenser module and a second condenser module, each condenser module including:
a housing having a front side, a back side, a first longitudinal side and an opposite, second longitudinal side, each of the first longitudinal side and the second longitudinal side defining an air inlet;
a heat exchanger assembly contained within the housing, the heat exchanger assembly including a first heat exchanger coil having a major surface facing the first longitudinal side and a second heat exchanger coil having a major surface facing the second longitudinal side, wherein a cross-section of the heat exchanger assembly is constant between the front side and the back side of the housing;
a fan assembly including a first fan aligned with the first heat exchanger coil and a second fan aligned with the second heat exchanger coil; and

wherein the plurality of condenser modules are stacked longitudinally within the frame such that the back side of the first condenser module is positioned directly adjacent the front side of the second condenser module the first longitudinal side of the first condenser module is arranged directly adjacent the first longitudinal side of the second condenser module, and the first heat exchanger coils of the first condenser module and the second condenser module are horizontally aligned adjacent the first longitudinal side over a length of the frame, and the second heat exchanger coils of the first condenser module and the second condenser module are horizontally aligned adjacent the second longitudinal side over a length of the frame.

2. The condenser according to claim 1 , wherein the plurality of condenser modules are identical.

3. The condenser according to claim 1 , wherein at least one of the first heat exchanger coil and the second heat exchanger coil is a micro-channel heat exchanger coil.

4. The condenser according to claim 1 , wherein the first heat exchanger coil is mounted to the first longitudinal sidewall and the second heat exchanger coil is mounted to the second longitudinal sidewall.

5. The condenser module according to claim 1 , wherein the fan assembly is mounted to the housing in a blow-through configuration.

6. The condenser according to claim 1 , wherein the fan assembly is mounted to a top surface of the housing in a draw through configuration.

7. The condenser according to claim 1 , wherein a divider extends along a center line between the first longitudinal side and the second longitudinal side to create a first modular portion and a second modular portion.

8. The condenser according to claim 7 , wherein the first modular portion and the second modular portion are identical.

9. The condenser according to claim 1 , wherein the heat exchanger assembly includes one of a V-shaped configuration, an A-shaped configuration, a U-shaped configuration, and a horizontal configuration.
