As the refrigerant passes through the indoor heat exchanger 108, the indoor fan 110 may be operated to bring air into contact with the indoor heat exchanger 108, thereby transferring heat from the air surrounding the indoor heat exchanger 108 to the refrigerant. The refrigerant may then reenter the compressor 116 after passing through the reversing valve 122.

To operate the air purification system 100 in the heating mode, the reversing valve 122 may be controlled to change the flow path of the refrigerant, the indoor metering device 112 may be disabled and/or bypassed, and the outdoor metering device 120 may be enabled. In the heating mode, refrigerant may flow from the compressor 116 to the indoor heat exchanger 108 through the reversing valve 122, the refrigerant may be substantially unaffected by the indoor metering device 112, the refrigerant may experience a pressure differential across the outdoor metering device 120, the refrigerant may pass through the outdoor heat exchanger 114, and the refrigerant may re-enter the compressor 116 after passing through the reversing valve 122, operation of the warm air, ventilation, and air conditioning system 100 in the heating mode being opposite to operation of the indoor heat exchanger 108 and the outdoor heat exchanger 114 in the cooling mode.

While the air purification system 100 is shown as a split system, including indoor units 102 that are separate from outdoor units 104, alternative embodiments of the hvac system 100 can include a package in which one or more components of the indoor units 102 are carried together with one or more components of the outdoor units 104 in a common housing or package. The hvac system 100 is shown as a ducted system in which the indoor units 102 are located remotely from the climate zone, thus requiring a duct to direct the circulating air. However, in alternative embodiments, the air purification system 100 can be used in non-ducted systems, wherein the indoor units 102 and/or the plurality of indoor units 102 associated with the outdoor unit 104 are substantially located in the space and/or area conditioned by the respective indoor units 102, thereby eliminating the need for air ducts to route the air conditioned by the indoor units 102.

It should be appreciated that the clean air supply rate (CADR) of the air purification system 100 may be defined as the product of the volumetric air flow (sometimes in cubic feet per minute or CFM) through the air purifier 200 multiplied by the air purifier efficiency of the air purifier 200. Thus, a relatively high CADR may generally be achieved by adjusting the volumetric air flow through air purifier 200 and/or by adjusting the efficiency of the air purifier such that the product of the two is relatively increased. In this embodiment, air purifier 200 may use an electrostatic precipitation process to clean the air. In some embodiments, air purifier 200 may include a powered field charger used to enable the electrostatic precipitation process. In some embodiments, varying the power supplied to the field charger may vary the resultant performance and/or air purifier efficiency of air purifier 200, and providing a relatively higher voltage to the field charger may increase the performance and/or air purifier efficiency of air purifier 200 when a relatively lower voltage is provided to the field charger compared to the performance and/or air purifier efficiency of air purifier 200. In some embodiments, air purifier 200 may be used to operate at one of three power level settings, high, medium, and low, each setting indicating a relative voltage level provided to the field charger.

In alternative embodiments, air purifier 200 may be used to selectively modulate and/or change power level settings over one or more ranges of power levels. For example, air purifier 200 may even be able to adjust the voltage provided to the field charger such that the air purifier efficiency of air purifier 200 may be adjusted over a relatively large range of values at which air purifier 200 may operate effectively. Still further, in alternative embodiments of air purifier 200, air purifier 200 may include other components that affect air purifier performance and/or air purifier efficiency of air purifier 200, as well as or in place of a field charger. When air purifier power settings and/or on-site charger power settings are discussed subsequently, it should be understood that intending to operate air purifier 200 at a relatively higher power setting is intended to control air purifier 200 and/or one or more components of air purifier 200 to have a first or higher performance rate and/or air purifier efficiency, while operating air purifier 200 power settings at a relatively lower power setting is intended to control one or more components of air purifier 200 and/or air purifier 200 to have a second or relatively lower performance and/or air purifier efficiency as compared to the first or higher performance and/or air purifier efficiency.

In some embodiments, system controller 106 may be operable to allow a user to control air purification system 100 to meet the user's demand for air to be cleaned by air purifier 200, which may include controlling (1) the volumetric flow of air through air purifier 200, (2) the performance and/or efficiency of air purifier 200, and (3) the duration of operation of air purifier 200 and/or indoor fan 110 to move air through air purifier 200.

Air purifier 200 may also include a field charger 208 and first and second collection units 204 and 205 for removing and collecting small impurities from the air. The field charger 208 is operable to ionize air proximate to the batteries 204 and 205, thereby charging particles in the airflow through the pre-filter 206. Then, the particles are collected by the first and second collection units 204 and 205, and the first and second collection units 204 and 205 are opposite in charge to the particles in the air.
