Problems solved by technology

[0009] In the case of using a motor vehicle for outdoor leisure, if warm water and cold water can be easily used, the comfort will be significantly improved. However, in the scheme described in the above-mentioned Patent Document 1, although the air conditioner in the vehicle room can be used to perform battery cooling Heating and cooling, but there is a problem that warm water and cold water cannot be supplied
[0010] In addition, the scheme described in the above-mentioned Patent Document 2, although the heating device of the motor vehicle can be used to supply warm water, cannot supply cold water, and since the air and water are directly heated by the air heating device to generate warm air and warm water , so there is the problem of low thermal efficiency and uneconomical

no. 1 approach

[0059] Below, based on Figure 1 ~ Figure 3 The first embodiment of the present invention will be described.

[0060] exist figure 1 2 shows a circuit diagram of a thermal cycle system for a vehicle that controls the air conditioning of the cabin of an electric vehicle and / or a hybrid vehicle, temperature adjustment of a battery, supply of warm water, and supply of cold water. The thermal cycle system for a vehicle includes an energy supply circuit C1, an energy absorption circuit C2, and a water circulation circuit C3.

[0061] Regarding the energy supply circuit C1, the electrothermal heater 11, the first passage switching valve 12 composed of a three-way valve, the heating core 13 as a heat exchanger for heating the interior of the vehicle, and the second passage composed of a three-way valve are switched. The valve 14, the battery heating and cooling unit 15 for adjusting the temperature of the battery serving as the driving power source, the third passage switching valv...

no. 2 approach

[0085] Next, based on Figure 4 A second embodiment of the present invention will be described.

[0086] In the first embodiment, one water circulation circuit C3 includes both the first heat exchanger 17 and the second heat exchanger 33 , but the second embodiment includes mutually separated first water circulation circuit C3A and second water circulation circuit C3B. The first water circulation circuit C3A includes a fourth water pump 35A, a warm water tank 36A, and a warm water supply valve 41A in a closed circuit, and the second water circulation circuit C3B includes a fifth water pump 35B, a cold water tank 36B, and a cold water supply valve 41B in a closed circuit.

[0087] According to this embodiment, warm water can be stored in the warm water tank 36A of the first water circulation circuit C3A, and cold water can be stored in the cold water tank 36B of the second water circulation circuit C3B, so that both warm water and cold water can be used simultaneously, further ...

Abstract

A heat circulation system for a vehicle, which can perform vehicle cabin air conditioning, battery heating and cooling and supplying of warm water and / or cold water, is provided. The system includes: an energy supply circuit (C1) that supplies heat energy supplied from a heat source (11) to at least a vehicle cabin heater (13) or a battery heater and cooler (15); and an energy absorption circuit (C2) that supplies cold energy supplied from a heat pump mechanism (21) to at least a vehicle cabin cooler (29) or the battery heater and cooler (15). The heat circulation system for a vehicle further includes a water circulation circuit (C3), and the water circulation circuit (C3) includes at least one of a first heat exchanger (17) that generates hot water by exchanging heat with the energy supply circuit (C1) and a second heat exchanger (33) that generates cold water by exchanging heat with the energy absorption circuit (C2).

Description

technical field [0001] The present invention relates to a thermal cycle system for a vehicle capable of generating warm water and cold water by utilizing an air conditioner and a battery heating and cooling device included in the vehicle. Background technique [0002] According to the following Patent Document 1, an air conditioner that heats or cools the interior of a motor vehicle is used, the heat medium generated by the air conditioner is used to heat the battery during heating, and the heat medium generated by the air conditioner is used to heat the battery during cooling. It is known to use refrigerants to cool batteries. [0003] In addition, according to the following Patent Document 2, the water in the water storage tank is heated to generate warm water by using the heat of an air heating device that heats air to generate warm air for heating, and the warm water is passed from the faucet to the vehicle interior. A combined heating / hot water supply system of interna...
