摘要:
The vehicle air conditioning device has a first refrigeration cycle and second refrigeration cycle that have a portion of a refrigeration pathway in common, and form different heat pump cycles; a first water-refrigerant heat exchanger included in the first refrigeration cycle, exchanges heat between a low-temperature and low-pressure refrigerant and the coolant of a heat-generating member of the vehicle, and vaporizes the refrigerant; a flow rate adjustment means that adjusts the flow rate of the coolant flowing through the heat-generating member and the first water-refrigerant heat exchanger; a detection means that detects a decline in the amount of refrigerant in the first refrigeration cycle due to the inflow of the refrigerant into the second refrigeration cycle; and a control means that, when a decline in the amount of refrigerant in the first refrigeration cycle has been detected, controls the flow rate adjustment means, reducing the flow rate of the coolant.
摘要:
A risk-degree setting unit (108) sets the degree of risk for the case where an inverter (103) performs conversion processing (inverter risk degree), and sets the degree of risk for the case where a storage battery (105) stores electrical energy (storage battery risk degree). A final output destination determination unit (109), based on the degrees of risk set by the risk-degree setting unit (108), determines the final output destination of electrical energy output from an electric motor (106), and controls the turning ON or OFF of a relay (110). The final output destination determination unit (109) turns the relay (110) ON when the storage battery (105) is determined as the final output destination of the electrical energy output from the electric motor (106), and turns the relay (110) OFF when the inverter (103) is determined as the final output destination of the electrical energy output from the electric motor (106).
摘要:
An onboard air conditioning device wherein the heating capability of air conditioning is improved, and gas is prevented from flowing into the vehicle interior even in the unlikely event that gas is produced by a battery. In this device, one end of an air flow channel is connected to an air conditioning unit for blowing temperature-regulated air into a vehicle interior, and the other end opens into the vehicle interior. The air flow channel draws air into the vehicle interior from the opening, the intake air is passed through a battery and heated by heat exchange, and the air is then sent to the air conditioning unit. The air conditioning unit sends the air from the air flow channel to a sensible heat exchanger, and after this air undergoes heat exchange with air taken in from another channel, the air is exhausted out of the vehicle interior.

摘要:
The vehicle air conditioning device is equipped with: a heater core that imparts heat to air flowing to the vehicle cabin interior by flowing a high temperature cooling liquid; a first water-refrigerant heat exchanger that exchanges heat between the cooling liquid and the high-temperature, high-pressure refrigerant in a heat pump, thus condensing the refrigerant; a flow rate adjustment means that adjusts the flow rate of the cooling liquid flowing through the heater core and the first water-refrigerant heat exchanger; and a control unit that performs air conditioning control. The control unit controls the flow rate adjustment means, and adopts a configuration that for a predetermined time period from the starting up of the heat pump, sets the flow rate of the cooling liquid to a second flow rate that is lower than a first flow rate during standard operating.
