Abstract: A modular HVAC-SHW/DHW system that provides comfort conditioning, sanitary hot water, and ventilation in the buildings is disclosed. The system includes HVAC units, SHW/DHW units, and one or more air-to-water heat pump (AWHP) units fluidically connected to the HVAC units and the SHW/DHW units through at least one water-to-water heat pump (WWHPs). The AWHP units are configured to enable the exchange of heat between the environment and the WWHPs, and the WWHP is configured to enable the exchange of rejected heat between any of the AWHP units, the HVAC units, and the SHW/DHW units. The system is designed in a packaged form factor or modular design, where the components/units of the system are configured within a housing that is easily installable at the desired locations in the building.

Abstract: A heating ventilation and air conditioning (HVAC) system includes an air handling unit having an outlet, at least one zone operably coupled to the outlet of the air handling unit, and at least one indoor air quality sensor operable to monitor an amount of one or more contaminants. The at least one indoor air quality sensor is arranged within the at least one zone. A controller operably coupled to the at least one indoor air quality sensor is configured to detect the occurrence of a fault or an unsatisfied indoor air quality condition and perform diagnostics to determine the cause of the fault or the unsatisfied indoor air quality condition.

Abstract: A heating ventilation and air conditioning (HVAC) system includes an air handling unit having an outlet, at least one zone operably coupled to the outlet of the air handling unit; and at least one indoor air quality sensor operable to monitor a level of one or more contaminants. The at least one indoor air quality sensor is arranged within the at least one zone. A controller operably coupled to the at least one indoor air quality sensor and is configured to determine when an amount of the one or more contaminants within the at least one zone exceeds an allowable threshold and implement a multi-level ventilation strategy to reduce the amount of the one or more contaminants within the at least one zone to below the allowable threshold.

Abstract: An environmental conditioning system for conditioning the environment of an occupiable region includes environmental conditioning hardware and a controller. The controller includes an occupancy module configured to receive ingress data associated with occupants entering the occupiable region for each of a first plurality of ingress iterations of a first prescribed time period. The controller further performs a first ingress rolling mean of the ingress data over the first plurality of ingress iterations, and compares at least the first ingress rolling mean to a first occupancy threshold. If the first occupancy threshold is exceeded by the first ingress rolling mean, the controller outputs a start command to the environmental conditioning hardware.

Abstract: A method of recommending a seat location is provided. The method comprising: receiving environmental parameter preferences from one or more user devices; receiving environmental parameters for one or more seat locations; determining a seat location recommendation for each of the one or more user devices in response to the environmental parameter preferences and the environmental parameters, the seat location recommendation identifying a seat location for each of the one or more user devices; and transmitting the seat location recommendations to each of the one or more user devices.

Abstract: A method of recommending a seat to a first user is provided. The method comprising: receiving environmental parameter preferences from a first user device; receiving environmental parameters for one or more seat locations, the one or more seat locations including a first seat location and a second seat location; determining one or more seat location recommendations in response to the environmental parameter preferences and the environmental parameters, the one or more seat location recommendations including a first seat location recommendation identifying the second seat location; and transmitting the one or more seat location recommendations to the first user device.
