HVAC system of vehicle with battery heating and cooling

A Heating, Ventilation and Air Conditioning (HVAC) system of a vehicle, comprising:

• a battery line thermally interconnecting a first radiator and a battery core, the battery line having a first pump connected such that a coolant flows in the battery line;
• a refrigerant line having a compressor, a condenser, and an evaporator, the refrigerant line having refrigerant flowing therein;
• an indoor cooling line thermally interconnecting an indoor HVAC cooling core and the evaporator, the indoor cooling line having a second pump connected such that the coolant flows in the indoor cooling line;
• an indoor heating line thermally interconnecting an indoor HVAC heating core and the condenser, the indoor heating line having a third pump connected therethrough such that the coolant flows in the indoor heating line;
• battery cooling lines branching from opposite side points of the battery core in the battery line, respectively, and connected to the indoor cooling line such that the coolant, which exchanges heat with the evaporator, flows to the battery core;
• battery heating lines branching from the opposite side points of the battery core in the battery line, respectively, and connected to the indoor heating line such that coolant, which exchanges heat with the condenser, flows to the battery core;
• and
• a first valve disposed at one of the opposite branching points in the battery line and configured to control flow of the coolant in the battery line, the indoor cooling line, and the indoor heating line.
