Heating (strictly)
The PECS device can increase the warm thermal sensation of the occupants. it can strictly heat with no other thermal management function (i.e., cooling)
Cooling (strictly)
The PECS device can increase the cool thermal sensation of the occupants. it can strictly cool with no other thermal management function (i.e., heating)
Ventilation
The PECS device that can improve indoor air quality in the occupant’s breathing zone. It can either supply outdoor air to dilute pollutants or treat the air locally.
Dual Thermal Management
A PECS device that can have heating and cooling functions (at different times of the year), depending on how it is operated.
Conduction
Devices that regulate personal thermal comfort by transferring heat through physical contact between solid surfaces, enabling localized heating or cooling without relying on air movement.
Convection
Devices that regulate personal thermal comfort by transferring heat through air movement, using natural or forced convection to provide localized heating or cooling.
Radiation
Devices that regulate personal thermal comfort by transferring heat through thermal radiation, where energy is emitted or absorbed in the form of electromagnetic waves (mainly infrared) without requiring direct contact or air movement
Evaporation
Outdoor Air Supply
Devices that regulate personal thermal comfort by leveraging the phase change of liquid to vapor, where heat is absorbed from the surface to overcome latent heat of vaporization, resulting in localized cooling without direct contact-dependent heat transfer.
Outdoor Air Supply
Outdoor Air Supply
Outdoor Air Supply
Devices that manage IAQ through diluting concentration of contaminants and pollutants at the breathing zone by bringing in clean outdoor air, i.e., through ventilation
Assistive Device
Outdoor Air Supply
Outdoor Air Supply
A local device that assists the main pecs device and is there to boost its performance (e.g., localized exhaust)
Building Attached
Building Semi Attached
Building Semi Attached
The PECS device is a part of the building structure. e.g.. ceiling fan or ceiling air nozzles
Building Semi Attached
Building Semi Attached
Building Semi Attached
The PECS device is independent of the building structure but is fixed to the structure with additional accessories. it can be relocated or moved with extra efforts. e.g. personalized ventilation supplying cool clean air to occupant with filters installed in the ducts
Building Detached
The PECS device is independent of the building structure and can be displaced as per need. e.g. cooling or heating chair
Wearable
The PECS device is a part of the occupant's clothing
