An air handler that provides for noise reduction without reducing the pressure of air supplied to a space below minimum levels. The air handler includes a plenum, which forms a passageway for air through the air handler; the plenum having a return side and a supply side, a fan positioned in the plenum to move air through the plenum, the fan having a suction side and a pressure side, and a conditioning apparatus in the plenum for conditioning air passing through the plenum. The air handler further includes a sound-attenuating panel, which has a first side and an opposed second side and is positioned in the plenum so that the panel extends at least partially across the plenum. The panel is configured and positioned to interact with the flow of air in the plenum to attenuate sound. The fan provides a pressure boost to air flowing through the plenum to counteract a pressure drop resulting from interaction between the air and the panel in the plenum and the conditioning apparatus.

An air handling unit has a first modular cabinet comprising a first profile, a second modular cabinet comprising a second profile that is complementary to the first profile, and the first profile comprises an alignment feature. An air handling unit has a heat exchanger cabinet comprising a first profile, a blower cabinet comprising a second profile complementary to the first profile, a first connector system disposed at least partially on each of the heat exchanger cabinet and the blower cabinet, and the first connector system is operable to releasably secure the first profile to the second profile. An air handling unit has a first modular cabinet comprising a first portion of a first connection system and a second modular cabinet comprising a second portion of the first connection system. A component of the first portion may be least partially received within the second portion.

A fan array fan section in an air-handling system includes a plurality of fan units arranged in a fan array and positioned within an air-handling compartment. One preferred embodiment may include an array controller programmed to operate the plurality of fan units at peak efficiency by computing the power consumed in various configurations and selecting the configuration requiring minimum power to operate.

A method for determining a measure of thermal energy delivered via a VAV box includes receiving an AHU supply air temperature, a VAV discharge air temperature, a space air temperature, and a VAV discharge flow rate. The measure of thermal energy delivered by the VAV box to the space during the first period of time is determined based at least in part on three or more of the received parameters. The determined measure of thermal energy delivered by the VAV box and a determined measure of thermal energy delivered by each of a plurality of other VAV boxes of the facility are aggregated over the first period of time, resulting in an aggregated measure of thermal energy. This may be used to adjust one or more control parameters to achieve a desired balance of energy consumption versus comfort, energy and/or health.

The object of this invention a regulation method for regulating an air conditioning system suitable for independently regulating the temperature of a plurality of zones. The air conditioning system comprises a thermal cycle machine. According to various embodiments, the thermal cycle machine is capable of delivering a cold airflow, a hot airflow or both. This flow is divided into smaller flows supplied to each of the zones to be regulated. The method according to the invention allows regulating these smaller flows as well as the operating conditions of the thermal cycle machine. According to various embodiments, the method additionally incorporates more complex variants involving variables such as pressure or thermal inertia. Likewise, according to one embodiment the air conditioning system incorporates a particular distributor configuration simplifying the installation of said regulation system.

An HVAC system employs a technique built around a system identification/modeling method that determines critical building loads and airflows experimentally without relying on design plans or statistical modeling approaches. Operation includes observing the dynamic response of individual room temperature, in response to a change of inlet air flow conditions (either air flow rate and/or supply air temperature). This empirically-based model enables development of an optimized control approach that minimizes conditioned airflow while meeting required ventilation, thermal, and humidification performance objectives. Building-wide performance is achieved by aggregating empirically determined room-level loads, thus ensuring that the coupled performance objectives can be achieved while minimizing energy use for every space within a building.

A method for operating an air handling unit of an HVAC system. The method includes opening an outside air flow control device to enable breathing air flow during a high outdoor air time period to a first zone having a first number of occupants and a second zone having a second number of occupants that is less than the first number of occupants. The outside air flow control device is then closed to enable conditioning air flow during a low outdoor air time period to the first and second zones. Further, a variable air volume (VAV) air flow control device provides desired amounts of breathing air to the first and second zones suitable for the first and second number of occupants, respectively. A VAV air temperature control device then provides conditioning air to the first and second zones having a suitable temperature for the first and second number of occupants.
