Infrared heating system for hvac&r system

A heating, ventilation, air conditioning, and refrigeration (HVAC&R) system, comprising:

• an air handling unit comprising a housing configured to receive and direct an air flow therethrough;
• a mounting wall disposed within the housing of the air handling unit, wherein the mounting wall comprises an aperture;
• an infrared heater assembly mounted to the mounting wall, wherein the infrared heater assembly comprises:
• a frame defining an air flow path extending through the frame and configured to direct the air flow through the frame, wherein the air flow path is aligned with the aperture of the mounting wall relative to a direction of the air flow through the housing;
• and
• a plurality of infrared emitters coupled to the frame and disposed within the air flow path, wherein the plurality of infrared emitters is configured to heat the air flow directed through the frame;
• and
• a controller communicatively coupled to the plurality of infrared emitters and configured to operate the plurality of infrared emitters to heat the air flow, wherein the controller is physically separate from the infrared heater assembly.

An infrared heater assembly, comprising:

• a frame comprising a plurality of panels coupled to one another, wherein the plurality of panels defines an air flow path extending through the frame from an air flow inlet of the frame to an air flow outlet of the frame;
• a first fin assembly coupled to the frame and disposed within the air flow path, wherein the first fin assembly comprises a first plurality of fins;
• a second fin assembly coupled to the frame and disposed within the air flow path, wherein the second fin assembly comprises a second plurality of fins;
• and
• a plurality of infrared emitters coupled to the frame and positioned between the first fin assembly and the second fin assembly, relative to a direction of an air flow through the frame and along the air flow path, wherein the plurality of infrared emitters is configured to heat the air flow, the first plurality of fins, and the second plurality of fins.
