The present disclosure relates generally to air intake filter assemblies, and more particularly to air intake assemblies for an outdoor portion of a heating, ventilation, and/or air conditioning (HVAC) system. In an embodiment, a filter assembly is configured to filter an airflow entering an air intake of a HVAC unit. The filter assembly includes a first layer of a first coarse mesh, a second layer of a second coarse mesh, and a fine filter disposed between the first layer and the second layer. Additionally, the fine filter includes an upper level and a lower level with respect to the airflow, and wherein the lower level facilitates accumulation of fine debris captured from the airflow entering the air intake of the HVAC unit.

The present disclosure relates generally to air intake filter assemblies, and more particularly to air intake assemblies for an outdoor portion of a heating, ventilation, and/or air conditioning (HVAC) system. In an embodiment, a filter assembly is configured to filter an airflow entering an air intake of a HVAC unit. The filter assembly includes a support structure and a plurality of filter slats, each having a fine filtration material, each disposed within the support structure, and wherein the plurality of filter slats is configured in a louvered relationship and actuated between a closed configuration through which the airflow passes and an open configuration through which the airflow passes.

A heating, ventilation, and/or air conditioning (HVAC) unit includes a cabinet defining a cabinet interior configured to house components of the HVAC unit. The cabinet includes an opening defining an air flow path between the cabinet interior and an external environment. The HVAC unit also includes a fan assembly including fan blades configured to move an air flow through the opening, wherein the fan assembly is configured to enable translation of the fan blades through the opening between a shipping arrangement in which the fan blades are disposed in the cabinet interior and an operational arrangement in which the fan blades are disposed in the external environment.

A heating, ventilation, and/or air conditioning (HVAC) unit includes a refrigerant circuit including a reheat coil and a condenser system, a first valve disposed along the refrigerant circuit and configured to modulate refrigerant flow to the reheat coil and to the condenser system, and a second valve disposed along the refrigerant circuit downstream of the first valve relative to a direction of the refrigerant flow through the refrigerant circuit. The condenser system includes a first condenser coil and a second condenser coil, and the second valve is configured to be actuated to control refrigerant flow to the second condenser coil.

The present disclosure relates to a fin heat exchanger, including a header, a set of tubes fluidly coupled to the header, and a mount configured to engage with and disengage from the set of tubes. The mount includes a fin section configured to extend between adjacent tubes of the set of tubes in an engaged mount configuration, and configured to be separated from the set of tubes in an unengaged mount configuration.

Removable fin heat exchanger systems and methods

A heating, ventilation, and/or air conditioning (HVAC) system has a refrigerant circuit that includes a compressor, a condenser system with a first set of tubes and a second set of tubes fluidly separate from the first set of tubes within the condenser system, and a valve positioned downstream of the compressor and upstream of the second set of tubes relative to a direction of refrigerant flow through the refrigerant circuit, in which the refrigerant circuit is configured to direct refrigerant through the first set of tubes and through the second set of tubes. The HVAC system further has a switch configured to detect an operating parameter and to instruct the valve to close based on the operating parameter such that refrigerant flow is blocked through the second set of tubes and refrigerant flow is enabled through the first set of tubes.

Low ambient operation of HVAC system

The present disclosure relates to a heating, ventilation, and/or air conditioning (HVAC) system that has a first circuit and a second circuit that each have a compressor and a condenser, a conduit extending from the second circuit downstream of the condenser to the first circuit upstream of the compressor, a valve along the conduit that may manage flow therethrough, and a controller that may operate the HVAC system in a first mode such that each circuit separately circulates the refrigerant in each circuit and transition to a second mode such that refrigerant-sharing occurs between the circuits. In response to a request to transition from the second mode to the first mode, the controller may determine an amount of refrigerant subcooling, compare the amount to a threshold value associated with the first mode, and instruct opening of the valve upon a determination that the amount is less than the threshold value.
