Problems solved by technology

[0011] However, when the heat pump system of the related art described above requires dehumidification while operating in the heating mode in winter, it must stop operating in the heating mode, change to the heating mode using the PTC heater, and then change to the cooling mode, so that due to the Noise and reduced durability due to frequent changes between cooling and cooling modes, and overall performance of the heat pump system
[0012] In addition, when the dehumidification mode is frequently operated, the power consumption increases due to the expansion of the use range of the PTC heater, so the overall driving distance with the same power is reduced

Abstract

A heat pump system for a vehicle may include an outdoor condenser, an expansion valve, an evaporator, a compressor, and an indoor condenser that primarily condenses the refrigerant compressed through the compressor and is connected with the outdoor condenser, in which the outdoor condenser, the expansion valve, the evaporator, the compressor, and the indoor condenser are connected through refrigerant pipes, a first valve disposed in the refrigerant pipe between the outdoor condenser and the expansion valve; a chiller connected with the first valve through the refrigerant pipe, between the evaporator and the compressor, and controls the temperature of the refrigerant by exchanging heat; a connection pipe selectively allowing some of the refrigerant flowing into the chiller in a dehumidifying mode; and a second valve disposed in the connection pipe.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2013-0148737 filed on December 2, 2013, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The invention relates to a heat pump system for a vehicle. More specifically, the present invention relates to a heat pump system for a vehicle, which increases the driving distance of the vehicle by reducing the use of the PTC heater, and which can utilize the The heating mode runs continuously in the dehumidification mode, improving its overall efficiency. Background technique [0004] Generally, an automatic air conditioning system includes an air conditioning module for heating / cooling the interior of the vehicle. [0005] Such an air conditioning module is designed to cool the interior of the vehicle using a heat exchange medium that is discharged from the compressor and exchanges heat through th...
