Problems solved by technology

In this case, frosting of the evaporator used for indoor heating in cold regions may lead to a decrease in heating efficiency, damage to the evaporator, etc.
[0007] However, in the air conditioning system described above, it has not been considered to use the heat of a heating element such as a fuel cell to remove the attached frost

[0026] figure 1 is a block diagram showing the air conditioning system according to the first embodiment.

[0027] Such as figure 1 As shown in , the air conditioning system 1 has a heat pump circuit 10 and a heat recovery circuit 30 .

[0028] The heat pump circuit 10 has a cooling side circuit 10a and a heating side circuit 10b. The cooling side circuit 10a lowers the temperature of the air used for cooling the vehicle interior by absorbing heat from the air supplied into the vehicle.

[0029] The heating-side circuit 10b raises the temperature of the air used for heating the vehicle interior by causing the air supplied into the vehicle to absorb heat.

[0030] First, the cooling side circuit 10a will be explained.

[0031] The cooling side circuit 10 a has a compressor 11 , a switching valve 14 , a condenser 12 , an expansion valve 15 , an evaporator 17 and a pipe 22 .

[0032] The inlet side of the compressor 11 has an outlet side of an evaporator 17 and an outlet sid...

Abstract

According to one embodiment, an air conditioning system includes a compressor, a condenser, an expansion valve, a switching valve, an evaporator, a pump, a radiator, and a heat storage unit. The switching valve performs switching so that the first heat transfer medium flows through the first flow path or the second flow path. The pump supplies the second heat transfer medium to the heat source. The heat storage unit has a heat storage material. The heat storage unit has a first heat exchange region in which heat is exchanged between the first heat transfer medium flowing through the first flow path and the heat storage material. The heat storage unit has a second heat exchange area provided upstream of the heat sink and in which the second heat transferred to the heat source Heat is exchanged between the medium and the heat storage material.

[0001] Cross References to Related Applications [0002] This application is based upon and claims priority from prior Japanese Patent Application No. 2011-210318 filed on September 27, 2011; the entire contents of which are incorporated herein by reference. technical field [0003] Embodiments described herein relate generally to air conditioning systems. Background technique [0004] In order to cool a heating element such as a fuel cell mounted on a vehicle, there is a cooling system that utilizes a heat transfer medium used for indoor cooling by an air conditioning system as a heat sink. [0005] For example, a cooling system is proposed that uses a heat transfer medium for indoor cooling as a heat sink to cool a heating element mounted on a vehicle via a heat exchanger, in which the air conditioning system uses An evaporator cooled in the room and a heat exchanger with heat storage material are connected in parallel via a switching valve. [0006] Here, in the air con...
