Abstract
A heating, ventilation, and/or air conditioning (HVAC) system includes a compressor section corresponding to a compressor, an additional section corresponding to at least an end portion of a heat exchanger, and a front coil block-off (FCBO) box configured to fluidly isolate the additional section from the compressor section, the additional section from an ambient environment, or both.
Claims20
A heating, ventilation and air conditioning (HVAC) system, comprising:
- a compressor section corresponding to a compressor;
- an additional section corresponding to at least an end portion of a heat exchanger;
- a compressor barrier block-off wall extending between and at least partially separating the compressor section and the additional section configured to at least partially isolate the additional section from the compressor section;
- a tube network in connection with the compressor and the heat exchanger, wherein the tube network comprises at least a first set of tubes made from a first material and a second set of tubes made from a second material, wherein the first material is different from the second material and the majority of the first set of tubes is positioned in the compressor section and the majority of the second set of tubes is located in the additional section.
A heating, ventilation, and air conditioning (HVAC) system, comprising:
- a compressor section corresponding to a compressor;
- an additional section corresponding to at least an end portion of a heat exchanger;
- a compressor barrier block-off wall extending between and at least partially separating the compressor section and the additional section configured to fluidly isolate the additional section from the compressor section;
- and
- a thermostatic expansion valve within the additional section configured to control refrigerant flow;
- wherein the thermostatic expansion valve has a greater distance from the compressor barrier block-off wall than the end portion of the heat exchanger.
A heating, ventilation, and air conditioning (HVAC) system, comprising:
- a compressor fluidly connected to a first set of tubes being of a first material;
- a heat exchanger having an indoor coil and a second set of tubes being of a second material and in fluid connection to the first set of tubes, wherein the second material is different to the first material;
- and
- a compressor barrier block-off wall disposed between the compressor and the heat exchanger, wherein the first set of tubes is positioned on the compressor side of the compressor barrier block-off wall and the second set of tubes is positioned on the heat exchanger side of the compressor barrier block-off wall.
