An HVACR fan and heater assembly accounts for the cyclonic flow produced by centrifugal blowers by placing a heater vertically and biased towards a side of a fan cabinet in order to increase and balance airflow through the heater, eliminating hot spots and fire risk and improving heater efficiency. A blockoff in the fan cabinet forces airflow within the cabinet to move through the heater. The positioning of the heater may vary depending on the direction of rotation of the centrifugal blower. The fan and heater assembly may further include baffles to direct the airflow from the centrifugal blower.

A heating, ventilation, air conditioning and refrigeration system includes a diffuser comprising a plurality of diffuser elements located between a blower driving airflow through the system and a refrigeration coil used to cool the airflow prior to the distribution of the airflow to a building. Locating diffusers between the blower and the refrigeration coil reduces the extent to which the airflow carries moisture from condensate on the refrigeration coil, and can prevent circulation of air backwards through the refrigeration coil.

Method and system for reducing moisture carryover in air handlers

Systems and methods to distribute airflow in an internal space of a transport unit are described. The airflow distribution system may include an airflow distributor forming an airflow passage with a roof of the transport unit. The airflow distribution system may be also configured to allow airflow to discharge from a gap between the airflow distributor and the roof. The gap may be provided by at least one spacer between the airflow distributor and the roof. A back end of the airflow distribution system may be configured to provide a back pressure to the airflow passage while allowing the airflow to discharge. In operation, a front end of the airflow distribution system may be configured to receive airflow. The airflow can be distributed along the airflow passage and be discharged from the gap and the back end.

An air flow mixer that mixes two or more air streams that may enter air moving equipment at significantly different temperatures. In particular, methods, systems and apparatuses are disclosed that are directed to an air flow mixer that is structured and arranged to promote cross flow of portions of the air streams relative to each other through the air flow mixer. The cross flow resulting from the structure and arrangement of the air flow mixer avoids sharp delineations or fluid borders between the air streams that can be caused, for example, by a relatively higher temperature of one of the air streams and a relatively lower temperature of another one of the air streams.

Devices and methods for enhancing heat exchanger airflow in a transport refrigeration system (TRS) of a refrigerated transport unit are provided. In particular, a fairing is provided on a top surface of a TRU to shield the TRU from an adverse effect of wind (e.g., ram air) and build a negative pressure at a heat exchanger fan delivery side of the TRU. The angle, shape and height of the fairing can be optimized to achieve a desired heat exchanger airflow through condenser coil(s), a radiator and/or intercooler of the TRU during operation.

Device and method for enhancing heat exchanger airflow

A transport refrigeration unit (TRU) for a transport refrigeration system (TRS) is described. The TRU can be configured to have an upper compartment to accommodate a compressor and an engine, and a condenser compartment that is generally positioned below the upper comportment. The condenser compartment can include a condenser and a fan at a bottom portion of the condenser compartment. The fan can be configured to blow air out of the condenser compartment in a downward direction from the bottom portion of the condenser compartment. The TRU can also have an evaporator compartment that is generally positioned behind the condenser compartment. The evaporator compartment can accommodate an evaporator that is generally positioned below the upper compartment. The evaporator compartment can have an air inlet and an air outlet that is positioned higher than the air outlet. In operation, airflow through the evaporator compartment is directed in a downward direction.
