Temperature adjustment device

Abstract

A temperature adjustment device (1) comprises a battery pack (8), a blower (2) for blowing temperature-adjusted air onto the battery pack (8), doors (3-6) for altering the air path of the temperature-adjusted air in accordance with an operation mode, a heat radiator (11) for heating the air blown onto a temperature adjustment object in a heating mode, an evaporator (13) for cooling the air blown onto the temperature adjustment object in a cooling mode, and a compressor (10) for discharging refrigerant to the heat radiator (11). The evaporator (13) is disposed in a lower position than the heat radiator (11). Provided is a temperature adjustment device whereby a temperature adjustment object can be both heated and cooled, and the device can be operated with conserved power and low noise when the needed cooling performance is low.

Description

technical field [0001] This application is based on Japanese Patent Application No. 2012-050833 filed on March 7, 2012 and Japanese Patent Application No. 2012-277333 filed on December 19, 2012, and their disclosures are incorporated herein by reference. Apply. [0002] The present disclosure relates to a temperature regulation device that performs temperature regulation by sending air to a temperature regulation object of a vehicle. Background technique [0003] Conventionally, there are secondary batteries that store electric power for running electric vehicles, hybrid vehicles, etc., electrical equipment that generates heat during use, and air conditioners in the vehicle interior as objects that require temperature adjustment. There are appropriate temperature ranges for performing the functions and appropriate temperature ranges for maintaining comfort in the above-mentioned temperature control objects, and a temperature control device that can adjust the temperature to...

Problems solved by technology

However, when the battery generates a large amount of heat during high-speed driving or climbing a hill, and the required battery cooling capacity is on the order of several kilowatts, sufficient cooling may not be possible.

In addition, the technology of Patent Document 2 can only cool the storage battery, and in order to perform both heating and cooling of the storage battery, it may be necessary to separately install heating equipment.

[0009] The technique of the above-mentioned Patent Document 3 is a device used for air conditioning of a vehicle interior space, but when it is applied to battery temperature control, even when the required battery cooling capacity is small (low load, etc.) ) also needs to drive the compressor, so noise to the surroundings can sometimes be a problem

In addition, in the device of Patent Document 3, the flow rate of the refrigerant becomes low when the load is low, so the oil return state to the compressor may deteriorate.
