Vehicle temperature adjusting apparatus, and vehicle-mounted thermal system

Abstract

A vehicle temperature adjusting apparatus for adjusting at least one of the air inside a vehicle compartment and a constituent component of a vehicle as an object for temperature adjustment is provided with: a heat capacity element (1) capable of storing heat; a refrigeration cycle (11) for absorbing heat from a low temperature side and dissipating heat on a high temperature side; heat exchanger units (14, 16) for exchanging the heat stored in the heat capacity element with a refrigerant of the refrigeration cycle (11); and heat imparting units (19, 31) for imparting the heat retained by the refrigerant of the refrigeration cycle (11) to the object for temperature adjustment. Thus, temperature adjustment can be performed effectively by using the heat capacity element.

Description

[0001] Cross References to Related Applications [0002] This application is based on Japanese Patent Application No. 2011-091847 filed on April 18, 2011 and No. 2012-038731 filed on February 24, 2012, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to a vehicle temperature control device that performs temperature control of at least one of air in a vehicle compartment and components in a vehicle, and an on-vehicle thermal system. Background technique [0004] Conventionally, in electrically driven vehicles such as electric vehicles, hybrid vehicles, and the like, electric motors are used to drive the vehicles by using electric energy supplied from a battery or the like. Electric power required for air conditioning the vehicle interior is also supplied from the battery. Therefore, the cruising range of the electric vehicle may be reduced during summer and winter, during which a large amount of energy ...

AI Technical Summary

Problems solved by technology

[0011] According to the conventional techniques of Patent Documents 3 and 4, in addition to the same problem as the conventional technique of Patent Document 2 mentioned above, the temperature difference between the battery temperature and the interior air temperature of the compartment is also insufficient in the cooling operation, which leads to poor cooling operation. sufficient cooling capacity

In addition, even when indoor air is introduced into the vehicle, there is also a problem of insufficient temperature difference, so it may be difficult to obtain sufficient heating / cooling capacity

In addition, in order to directly introduce air from the room into the vehicle, a hose is required, which complicates the structure of such a system

[0012] In addition, although Patent Documents 3 and 4 describe a method of how heat (ie, heat energy) at the time of charging is stored in a battery (ie, a heat-capacitive element), Patent Documents 3 and 4 do not describe how to store Method for storing remaining heat in a vehicle in travel-related components such as batteries

Furthermore, although Patent Documents 3 and 4 have described the control flow of the pre-air conditioning, there is no disclosure of the control flow for accumulating heat (ie, thermal energy) in the battery (ie, heat capacitive element)
