Methods and systems described perform air cleaning and/or sanitization in a heating, ventilation, air conditioning, and/or refrigeration (HVACR) system by detecting a concentration of airborne contaminants in a space serviced by the HVACR system. The detected concentration of airborne contaminants is determined whether it exceeds a threshold relative to a capacity of a first air cleaner. When the detected concentration of airborne contaminants exceeds the threshold, a second air cleaner is selected and enabled to be activated in the space. When the detected concentration of airborne contaminants does not exceed the threshold, the first air cleaner is selected and enabled to be activated in the space. The first air cleaner has a cleaning material different from the second air cleaner, and the first air cleaner, relative to the second air cleaner, treats the space at a lower concentration of airborne contaminants. The second air cleaner includes specifically designed cleaner modules.

A vehicular air conditioner includes a casing, a blower fan, and a heating heat exchanger that is disposed in the casing. The heating heat exchanger is disposed downstream of the blower fan. The blower fan is disposed to extend over a first outside air space, a second outside air space, a first inside air space, and a second inside air space. The rotational direction of the blower fan is set so that each of the plurality of blades of the blower fan passes through the first inside air space, the first outside air space, the second outside air space, and the second inside air space in this order when the plurality of blade are rotating.

An air-conditioning control system includes an air-conditioning device mounted in a host vehicle, a determination unit mounted in the host vehicle or a server and configured to determine whether a boarding position at which a boarding event in which an occupant boards the host vehicle occurs is a point with a predetermined attribute, and a control unit mounted in the host vehicle and configured to control the air-conditioning device based on a determination result from the determination unit. The control unit sets a ventilation capacity of the air-conditioning device to be greater when the determination unit determines that the boarding position is a point with the predetermined attribute than when the determination unit does not determine that the boarding position is a point with the predetermined attribute.

Technologies are provided for preventing a working fluid leak from pooling and thus diluting any leaked working fluid from air within a condenser and/or evaporator compartment of the CCU. This can include a computer-readable medium that stores executable instructions that, upon execution, prevent a working fluid leak from pooling within a climate-control unit (CCU) of a transport climate control system. This also includes detecting fulfillment of activation threshold conditions in connection with the CCU. Also, this includes activating a fan in at least one of a condenser unit and an evaporator unit included in the CCU to dilute leaked working fluid from air within the CCU. Further, this includes detecting fulfillment of de-activation threshold conditions and de-activation of an activated fan.

There is provided a vehicle comprising a thermal conditioning system and a cabin. The thermal conditioning system comprises a fan (102), a first heat exchanger (104), an outside air duct (112), a cabin air duct (114), a sensor, and a control unit (122). The fan is configured to generate a flow of air. The first heat exchanger is arranged to transfer heat to the flow of air. The thermal conditioning system is configured to be operated in a first mode and a second mode. In the first mode, the fan rotates in a first direction to direct the flow of air along a first flow path. In the second mode, the fan rotates in a second direction opposite to the first direction to direct the flow of air along a second flow path. The sensor is arranged to provide a signal representative of a temperature of a part of the vehicle. The control unit is configured to switch the thermal conditioning system between the first mode and the second mode based on the signal.

A vehicular air-conditioning device includes an inside air temperature detector, an inside air-conditioning portion, and an air-conditioning controller. The inside air-conditioning portion includes a temperature adjuster and a blower. The air-conditioning controller includes an auto control portion, an open signal detector, a thermal load determiner, and a power saving control portion. The auto control portion is configured to perform an auto control. The open signal detector is configured to detect an open signal. The thermal load determiner is configured to determine whether a thermal load on the passenger compartment exceeds an air-conditioning capacity of the auto control. The power saving control portion is configured to perform a power saving control to limit an increase of a power consumption regardless of the inside air temperature when the open signal is detected and it is determined that the thermal load exceeds the air-conditioning capacity of the auto control.

A portable air purifier may include a case having an accommodation space, a front side and a rear side of which are open; a fan assembly accommodated in the accommodation space and including a blower fan; a fan cover disposed in front of and coupled to the fan assembly in the accommodation space; and a filter module disposed behind the fan assembly in the accommodation space. The case may include a first support surface that protrudes from an inner circumferential surface of the case and disposed behind the fan cover to face the fan cover, and a second support surface that protrudes from the inner circumferential surface of the case and disposed in front of at least a portion of the filter module to face the at least a portion of the filter module. The fan cover and the filter module may be coupled in a frontward-rearward direction with the first support surface and the second support surface interposed therebetween and may be fixed to the case.

The present application relates to an air conditioning method and system, a vehicle, and a storage medium. The method comprises: determining an ambient temperature inside the vehicle; determining an operating state of a temperature regulation unit and a minimum air volume of an odor regulation unit in the operating state; receiving a setting of an intensity level of the odor regulation unit, wherein the temperature regulation unit shares an air passage with the odor regulation unit; and determining an air volume of the odor regulation unit according to the ambient temperature, the operating state, the minimum air volume, and the intensity level. According to this method, the release degree of the fragrance or the like inside the vehicle may be precisely controlled.

Disclosed are a vehicle and an air-conditioning control method therefor that are capable of executing an after-blow function for an air-conditioning system without concern about discharge of a battery. The method of controlling an air-conditioning system of an eco-friendly vehicle includes determining a remaining time to a destination when a first condition related to the state of the vehicle and setting of the destination and a second condition related to an indoor temperature of the vehicle are satisfied, determining the state of the air-conditioning system related to condensation water of an evaporator of the air-conditioning system when the remaining time is equal to or less than a first time, and activating an after-blow function to stop the cooling function of the air-conditioning system and to operate a blower based on the determined state of the air-conditioning system.

A computer includes a processor and a memory, the memory storing instructions executable by the processor to heat a passenger cabin of a vehicle, suppress a climate control limiter that prevents an air blower of a climate control component from operating when an engine coolant temperature exceeds a temperature threshold, and actuate a motor on an air pump to introduce air external to the vehicle to the passenger cabin.
