An air purification device for a vehicle includes: a sorption device provided with a sorbent; an air intake duct for sucking air in a vehicle cabin; an outlet-side three-way valve connected to the sorption device; an air supply duct for blowing air into the cabin; an exhaust duct for discharging air to outside of the cabin; a blower; a heater; and a controller. The controller selectively executes a purification mode in which air in the cabin is sent into the sorption device at a purification temperature, and purified air from which moisture and carbon dioxide have been removed by the sorbent is blown into the cabin, and a first regeneration mode in which air heated to a first regeneration temperature is sent into the sorption device, and exhaust air containing moisture and carbon dioxide released from the sorbent is discharged to the outside of the cabin.

A cooling and heating system for a motor vehicle comprises a heat pump, a controller, a low temperature radiator in thermal communication with the heat pump, a passenger cabin heat exchanger in thermal communication with the heat pump, and a defrost system comprising a bypass coolant loop in selective fluid communication with the low temperature radiator. When in the heating mode, the controller opens a solenoid valve and activates a coolant heater in the bypass coolant loop upon detecting operation of the heat pump outside of a predetermined normal operating range and upon detecting an ambient temperature below a predetermined temperature. The controller de-activates the coolant heater upon detecting operation of the heat pump within the predetermined normal operating range. The controller may also de-activate close the solenoid upon detecting operation of the heat pump within the predetermined normal operating range.
