Heat pump system for vehicle

Abstract

A heat pump system for vehicle includes a cooling device including a radiator and a first water pump by a cooling line and circulating a coolant along the cooling line to cool an electric component; abattery module provided on a battery cooling line selectively connected to the cooling line through a first valve; a HVAC module including an internal heater connected to the cooling line through a first connection line, a cooler connected to the battery cooling line through a second connection line, and an opening or closing door provided between the internal heater and the cooler and controlling external air passing through the cooler to be selectively introduced into the internal heater depending on cooling, heating, and heating and dehumidifying modes of the vehicle; and a centralized energy (CE) module connected to each of the battery cooling line and the cooling line.

Description

[0001] Cross References to Related Applications [0002] This application is based upon and claims the benefit of priority from Korean Patent Application No. 10-2017-0100982 filed with the Korean Intellectual Property Office on Aug. 9, 2017, the entire contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates to a heat pump system for a vehicle. More particularly, the present disclosure relates to a heat pump system for a vehicle for cooling or heating the interior of the vehicle by selectively using a high-temperature coolant and a low-temperature coolant, respectively. Background technique [0004] An air conditioner for a vehicle generally refers to an air conditioner that circulates a refrigerant for heating or cooling the interior of the vehicle. [0005] In order to maintain a comfortable interior environment, the air conditioner that keeps the interior of the vehicle at an appropriate temperature regardless of cha...

Problems solved by technology

[0012] Therefore, the size and weight of the cooling module provided at the front of the vehicle inevitably increase, and the layout of connection pipes supplying coolant or refrigerant to each of the heat pump system, cooling equipment, and battery cooling system in the engine room becomes complicated.

[0013] In addition, since the battery cooling system that warms up or cools the battery according to the state of the vehicle is separately provided so that the battery exhibits optimum performance, a plurality of valves for connecting the respective connection pipes to each other are used, and since the valves Noise and vibration generated by frequent opening or closing operations are transmitted to the interior of the vehicle, reducing ride comfort
