A heat pump system for a vehicle having a complex valve device including a three-way valve, an on-off valve, expansion means and connection blocks are formed integrally with one another, the three-way valve part being connected to the refrigerant circulation line of an inlet of the exterior heat exchanger such that the refrigerant selectively bypasses the exterior heat exchanger, the on-off valve part being connected to an inlet of the bypass line to open and close the bypass line. Connection blocks connect the three-way valve part and the on-off valve part with the refrigerant circulation line of an outlet of the exterior heat exchanger to communicate with each other. Expansion means are connected to an inlet of the three-way valve part to selectively expand refrigerant discharged from an interior heat exchanger. All functions of the heat pump system are thus conducted through a refrigerant control of the complex valve device.

Heat pump system for vehicle

Disclosed therein are a heat pump system for a vehicle and a method of controlling the heat pump system, which determines that frosting begins on an exterior heat exchanger and carries out a defrosting control if a difference value between outdoor temperature and refrigerant temperature of an outlet side of the exterior heat exchanger is above a frosting decision temperature in a heat pump mode, thereby increasing frost-prevention and defrosting effects and enhancing heating performance and stability of the system because the system recognizes the beginning of frosting on the exterior heat exchanger at a proper time so as to carry out the defrosting control.

A heat pump system including a water-cooled type heat exchanger, which is a heat supply means, mounted on a first bypass line bypassing a second indoor heat exchanger to collect waste heat of vehicle electric devices to thereby enhance a heating efficiency of the heat pump system. The heat pump system for a vehicle includes: a branch line for connecting a refrigerant circulation line of the second indoor heat exchanger and the first bypass line with each other; a second bypass line, which bypasses an outdoor heat exchanger; and a control part that controls a flow of the indoor air to be introduced into an air-conditioning case, whereby the heat pump system can minimize influences of the outdoor air of low temperature even when the outdoor temperature is below zero, enhance the operation and the heating performance of the heat pump system by collecting waste heat of the vehicle electric devices and heat sources of the indoor air, and increase the mileage of the vehicle by minimizing operation of an electric heater.

Disclosed therein are a heat pump system for a vehicle and a method of controlling the heat pump system, which variably controls only a compressor if the number of revolutions of the compressor is less than the upper limit of the number of the maximum revolutions of the compressor and operates an electric heater only when the number of revolutions of the compressor reaches the upper limit of the number of the maximum revolutions of the compressor in order to satisfy a target discharge temperature in a heat pump mode, thereby preventing that convergence of an air discharge temperature of the interior of the vehicle is deteriorated or becomes unstable when the compressor and the electric heater are variably controlled at the same time in order to satisfy the target discharge temperature.

The present invention relates to a cooling and heating cabinet device of a rear seat side for a vehicle using a thermoelectric module that is mounted between rear seats of a vehicle, having cooling and heating functions and further having an arm-resting function irrespective of its activation as the cooling and heating device, and that makes the exhaust fan activated by the control of the controller of the air conditioning system, thereby achieving the air-refreshing function as well as the cooling or heating mode function of the cooling and heating cabinet.
