摘要:
In a vehicle air-conditioning system, an evaporator (9) is disposed in an air-conditioning case (10) to form a bypass passage (16) through which air bypasses the evaporator, and an opening degree of the bypass passage is adjusted by a bypass door (17). When a vehicle engine (4) operates, the system performs a cold-storing mode where cold quantity stored in condensed water on the evaporator is increased. On the other hand, when operation of the vehicle engine is stopped, the system performs a cold-releasing mode where air passing through the evaporator is cooled by cold released from frozen condensed water. During the cold-storing mode and the cold-releasing mode, temperature of air blown into a passenger compartment can be adjusted by adjusting the opening degree of the bypass passage. Thus, in the vehicle air-conditioning system, cold-storing quantity in the evaporator can be improved while power-saving effect of the vehicle engine is improved.
摘要:
The invention relates to a method for controlling a coolant circuit (2) of an air conditioning system (4) for a vehicle. According to said method, a compressor (10) that is located in the coolant circuit (2) is controlled in accordance with an evaporator temperature controller (VR) and a load torque limitation function (22) that is integrated into said evaporator temperature controller (VR).
摘要:
An air conditioning control system which is provided in a vehicle includes an air conditioning device (10) and a controller (40). The controller is configured to acquire vehicle outside humidity information representing humidity when a start switch (5) of the vehicle is turned on, execute outside air introduction processing for making an outside air introduction ratio of the air conditioning device greater than 0% in an off state of the start switch (5), and when a first condition that the outside air introduction processing is executed is satisfied, calculate vehicle inside absolute humidity of the vehicle in an on state of the start switch (5) with absolute humidity based on the acquired vehicle outside humidity information as an initial value.
