Title:
HEAT PUMP SYSTEM FOR VEHICLES
Document Type and Number:
Japanese Patent JP2021037931
Kind Code:
A
Abstract:
To provide a heat pump system for vehicles.SOLUTION: The vehicle heat pump system of the present invention regulates the temperature of the battery module by using one chiller in which the refrigerant and the cooling water exchange heat. By recovering the waste heat generated from the electrical components and battery modules and using it for room heating, the system improves heating performance and efficiency. The system can maximize the heating performance by applying a gas injection portion that operates in the heating mode or dehumidification/heating mode of the vehicle to increase the flow rate of the refrigerant.SELECTED DRAWING: Figure 1
