Present embodiments relate to ionization of air flow within heating, ventilation and air conditioning (HVAC) systems. More specifically, but without limitation, present embodiments relate to ionization systems, for example bipolar ionization, which are controlled in part by a signal from or powered by the blower motor controller of the HVAC system so that the ionization system functions when the blower is on.

A treadmill may include two separate left and right belts rotating around two sets of rollers, four legs having an adjustable height via air suspension to customize an inclination of the treadmill, a thermoelectric assembly, a fragrance assembly having a rotating fragrance cartridge to emit various smells toward a user of the treadmill, a display on which exercise programs are played, and an attachment module having a dispensing tray on which treats are dispensed. A handle of the treadmill may have a sensor to sense a height and front-rear position, and a belt divider provided between the left and right belts may have position or proximity sensors to sense a left-right position. An inclination of the treadmill may be automatically adjusted according to positions detected by the sensors, and the fragrance assembly, attachment module, and inclination may be automatically operated in accordance with an exercise program played on the display.

Provided is a discharge device that can improve the efficiency of generating reactive species. A discharging unit that discharges in response to an application of a voltage protrudes from a housing. The discharging unit is disposed in a duct through which gas flows. An upstream support is disposed upstream of the discharging unit in a direction of gas flow without overlapping the discharging unit. The upstream support protrudes further from the housing than the discharging unit. The upstream support includes a root portion joined to the housing. The root portion includes a widened portion that is disposed in the duct and that protrudes toward the discharging unit when viewed in the direction of gas flow.

Ionization systems and methods include moving air into contact with one or more ion generators and then past an ozone removal assembly to remove at least some ozone from the air. The air may be moved by a fan and may be filtered before contacting the one or more ion generators. The amount of one or more of the following of the air may be measured: the amount of ions, particulates, temperature, humidity, and other relevant factors. The ionization amount may be adjusted based on one or more of the measured amounts. The one or more ion generators and ozone removal assembly may be constructed as part of a single unit so they can be removed and replaced easily.
