Vehicle compartment temperature control device

Abstract

Provided is a vehicle compartment temperature control device that can save power whilst also ensuring the thermal comfort of a passenger. This vehicle compartment temperature control device 10 can control the thermal comfort of a passenger in a seated posture in a seat. The device comprises: first interior members having a temperature control mechanism layer 13 in a front part 1a, an intermediarypart 1b, a front centre part 2c, a front lower part 2g, a front-surface lower part 4f, a seat cushion 5a and a right surface front upper part 6b, said parts constituting a first area in which the temperature of the legs of the passenger can be regulated; second interior members having a temperature control mechanism layer 13 different from the temperature control mechanism layers 13 in the first area in a steering wheel 3, a front-surface centre part 4e and a seat back 5b which constitute a second area which is positioned above a first interior members and in which the temperature of the above-leg region of the passenger can be regulated; and an ECU 30. The ECU 30 performs control so that the temperature of the temperature control mechanism layers 13 in the first area is higher than the temperature of the temperature control mechanism layers 13 in the second area.

Description

technical field [0001] The present invention relates to an indoor temperature control device for a vehicle, and more particularly to an indoor temperature control device for a vehicle capable of controlling the thermal comfort of an occupant in a sitting posture. Background technique [0002] From the viewpoint of warming the head and warming the feet, vehicle air conditioners have conventionally provided underfoot outlets capable of supplying warm air to the occupant's feet to increase the ambient temperature around the occupant's lower limbs. [0003] In the environment of the vehicle interior, the occupied space of the occupant is narrow, the posture is restricted, and the thermal insulation between the occupant and the external environment is low. Therefore, a large amount of energy consumption is required to ensure the thermal comfort of the occupant. [0004] Here, the thermal comfort is defined by ASHRAE (American Society of Heating, Refrigerating, and Air-Conditionin...

AI Technical Summary

Problems solved by technology

[0013] However, when a large number of temperature control devices such as heating panels are installed on the inner wall of the vehicle, there is a concern that the production cost will increase due to the increase in the number of parts of the vehicle.

In addition, the power consumption for operating a large number of heating plates increases, and the expected power saving may not be ensured.
