The evaluation data includes the power consumption of the air conditioner.

There is described a system and method for high ventilation using outdoor air in an indoor area comprising an HVAC unit and a controller. The HVAC unit includes at least one damper and a fan. The controller detects an activation of an emergency purge mode, adjusts the at least one air damper to allow a maximum of outside air to flow through the HVAC unit without circulating return air, and establishes a fan speed of the fan for maximum outside airflow through the HVAC unit. The controller also modifies the fan speed of the fan based on an occupant comfort criteria without regard to energy efficiency of the HVAC unit. The fan speed is modified based on a delta enthalpy of the HVAC unit and a nominal capacity of the HVAC unit.

An apparatus is provided for controlling environmental conditions using a fan and a light in connection with a building having a space including a partition, such as a wall. The apparatus may include a control adapted for being mounted to the partition and for coordinating the control of the fan and the light based on a sensed condition, such as temperature or occupancy. Groups of like devices for controlling environmental conditions may be similarly controlled, such as using control. Control may also provide an indication of an operational state of the device(s) controlled by it, or provide for control based on a preference of one or more people upon detecting their presence. Related methods are also described.

The present disclosure relates to a heating, ventilation, and/or air conditioning (HVAC) system including a controller configured to detect a presence of an occupant in a zone of a plurality of zones. The controller is also configured to determine a priority level of the occupant and control operation of the HVAC system to prioritize supply of conditioned air to the zone of the plurality of zones over remaining zones of the plurality of zones based on the priority level of the occupant.

A radiant air conditioning system for controlling comfortable and healthy indoor environment based on infrared sensing technology is disclosed, which comprises air source heat pump outdoor unit, plate evaporator, circulating water pump, etc. Accurate control of air humidity by installing an indoor dehumidification terminal can reduce the surface temperature of radiant cooling terminal and increase the installed area, which will significantly improve the radiant heat exchange between the terminal surface and the human body surface.
