A roof-type air conditioner is provided in which condensate water generated during interior cooling by an air conditioning unit is collected in a collecting unit to prevent the condensate water from flowing into an interior space of a vehicle. Due to accumulation of the condensate water, the condensate water collected by the collecting unit is discharged to the outside of the vehicle to prevent overflow and contamination of condensate water.

Roof-type air conditioner

A heat pump system for a vehicle is configured to perform cooling or heating of the vehicle interior by using a natural refrigerant, and efficiently adjust the temperature of the battery module by using a single chiller that heat-exchanges refrigerant and coolant.

Heat pump system for a vehicle

An air-conditioning system for mobility vehicles is capable of introducing outside air into a front portion and a rear portion of a housing in which a heat exchanger is mounted and capable of selectively changing the introduction direction of the outside air, adjusting the amount of heat exchange between the heat exchanger and the outside air depending on the travel direction of a mobility vehicle or whether or not a heat pump is used, thus improving the operational efficiency of the heat exchanger.

Air-conditioning system for mobility vehicles

An embodiment heat pump system for a vehicle includes an air conditioner unit and a chiller.
