Title:
AIR CONDITIONER FOR VEHICLE
Document Type and Number:
Japanese Patent JP2020019337
Kind Code:
A
Abstract:
To provide an air conditioner for vehicle which can prevent damage of a compressor due to liquid compression when defrosting an outdoor heat exchanger, and also can prevent over-cooling of a battery or the like.SOLUTION: An air conditioner for vehicle comprises a temperature control device 61 for temperature control object which circulates a heat medium to a temperature control object such as a battery 55 thereby controlling a temperature thereof. The temperature control device for temperature control object has a coolant-heat medium heat exchanger 64 which performs heat exchange between a coolant and the heat medium, and heat medium heating heater 66A, 66B. The coolant discharged from a compressor 2 is thermally radiated at an outdoor heat exchanger 7, and is pressure-reduced, and thereafter, a defrosting operation, in which heat is absorbed from the heat medium by the coolant-heat medium heat exchanger, is executed. In the defrosting operation, a temperature of the temperature control object is so controlled by the heat medium heating heater as to be a prescribed lower limit value TL or more.SELECTED DRAWING: Figure 1
