Heat management system for vehicle and method for controlling the same

A heat management system for a vehicle, the system comprising:

• an evaporator disposed in an air conditioning device;
• an expansion valve disposed on an upstream of the evaporator;
• a battery chiller disposed in parallel with the evaporator, cooling a coolant by heat-exchange between the coolant and a refrigerant supplied from the air conditioning device, and cooling a battery using the cooled coolant;
• a compressor compressing the refrigerant;
• and
• a controller:
• determining whether a delayed operation condition of the compressor is satisfied while the compressor is not operated,
• controlling the compressor to delay operation thereof based on determining that the delayed operation condition of the compressor is satisfied,
• determining whether a battery cooling condition is satisfied based on the determining that the delayed operation condition of the compressor is not satisfied, and
• controlling the compressor to be operated based on the determining that the battery cooling condition is satisfied.
