Problems solved by technology

Therefore, the heating performance may be severely deteriorated, the heating load may increase due to an increase in power consumption, and the mileage may be shortened when driving while heating
[0014] In addition, since the heat for converting liquid refrigerant into gaseous refrigerant is insufficient when liquid refrigerant flows into the internal condenser, compression efficiency may deteriorate, heating performance may deteriorate severely when the air temperature is low, and when liquid refrigerant The system may be unstable when flowing into the compressor and the durability of the compressor may deteriorate
[0015] Also, in the dehumidification mode that removes moisture from the vehicle cabin, noise and vibration may occur due to frequent opening / closing operations of the two-way valve

Abstract

The invention discloses a heat pump system for a vehicle, including a water cooled condenser that uses a coolant as a heat exchange media and uses waste heat generated from a motor and an electronic device to improve heating performance, efficiency, and dehumidifying performance. A control method is also described.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2011-0025613 filed March 23, 2011, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to a heat pump system for a vehicle and a control method thereof. More specifically, the present invention relates to a heat pump system for a vehicle in which a water-cooled condenser is applied to an electric vehicle, and waste heat from electric motors and electronic equipment is used to improve heating performance and dehumidification performance, and also relates to the heat pump system for a vehicle control method. Background technique [0004] Generally, an air conditioning system for a vehicle includes an air conditioning module for heating or cooling a cabin of the vehicle. [0005] This air conditioning module circulates a heat exchange medium through a c...
