As shown in the figure, the radiator 11 for dissipating water heated to a predetermined temperature by heat generated in the engine 10 by heat exchange due to friction with external air as the vehicle progresses, and the engine 10 described above. It is composed of a water pump 12 for forcibly circulating water while being driven by, and a thermostat 13 installed between the engine 10 and the radiator 11 to convert the water circulation path according to the temperature.

Reference numeral A denotes a cooling device. The structure of the cooling device described above includes a compressor 20 which sucks a refrigerant, compresses the same into a gaseous state of high temperature and high pressure, and discharges the refrigerant, and the refrigerant discharged from the compressor 20. A condenser 21 for liquefying liquid at a high temperature and high temperature by heat exchange with outdoor air, and a receiver 22 for temporarily storing a refrigerant liquefied in the condenser 21 and removing water and foreign substances from the refrigerant. And an expansion valve 23 that thermally expands the refrigerant flowing through the receiver 22 to create a gas and liquid state at low temperature and low pressure, and is disposed between the condenser 21 and the expansion valve 23 and is heated at a high temperature. A high pressure pipe 24 through which a high pressure refrigerant circulates is provided, and the refrigerant thermally expanded through the expansion valve 23 is evaporated by the blower 25 when passing through several pipes (not shown). While vaporizing And the evaporator 26 to absorb heat from above, is disposed between the above-mentioned expansion valve 23 and the compressor 20 is configured is provided with a low-pressure pipe 27 for low-temperature and low-pressure refrigerant circulates.

In addition, reference numeral B denotes a heating device, and the structure of the heating device described above is configured to supply warm air to the room by receiving heat heated to a predetermined temperature while circulating the water jacket in the engine 10 to heat exchange the inside. The hot water which is connected to the heater unit 30 and the other side of this heater unit 30, supplies hot water from the engine 10 to the heater unit 30, and circulates the heater unit 30 to the engine 10. The hot water supply and return lines 31 and 32 to return and the hot water valve 33 installed at a predetermined position of the hot water supply line 21 to regulate the hot water supplied from the engine 10 to the heater unit 30. It is composed.

On the other hand, between the cooling device (A) and the heating device (B) described above, the cold and warm storage 100 having the functions of the refrigerating and warming storage is installed.

The above-described cooling and warming chamber 100 is a refrigerant circulation pipe 101 branched from the low pressure pipe 27 between the expansion valve 23 and the evaporator 26 of the above-mentioned cooling device (A) is piped to the bottom surface It is connected to the low pressure pipe 27 between the evaporator 26 and the compressor 20 so as to circulate the refrigerant.

Hereinafter, the operation of the present embodiment configured as described above will be described.

First, when the driver switches the indoor temperature control lever (not shown) to the cooling area after starting the vehicle, the compressor 20 is driven by the engine 10 to compress the refrigerant into a gas state of high temperature and high pressure. Discharge from When the refrigerant discharged from the compressor 20 flows into the condenser 21 and at the same time exchanges heat with outdoor air to liquefy the liquid to a medium temperature and high pressure, the receiver 22 temporarily supplies the liquefied refrigerant. It removes water and foreign substances in the liquefied refrigerant by holding in. As such, the refrigerant from which moisture and foreign matter have been removed from the receiver 22 flows into the expansion valve 23 through the high pressure pipe 24 and at the same time, the refrigerant is adiabaticly expanded by the expansion valve 23 so as to provide a low temperature and low pressure gas and The liquid is exchanged with the air in the room through the low pressure pipe 27 to supply cold air to the room, and is delivered to the evaporator 26 for cooling the room to a predetermined temperature while some refrigerant is branched from the low pressure pipe 27. As the refrigerant is circulated through the coolant circulation pipe 101 at the bottom of the cold / warmer 100, the bottom of the cold / warmer 100 becomes cold to function as a refrigerator. In addition, the refrigerant circulated through the evaporator 26 and the cold / warmer 100 is sucked into the compressor 20 to be compressed and circulated in a gaseous state of high temperature and high pressure as described above.

Next, when the driver switches the indoor temperature control lever (not shown) to the heating zone, the hot water valve 33 installed on the hot water supply line 31 is switched to open the supply line to the engine 10. Water heated to a predetermined temperature is supplied to the heater unit 30. When the air in the heater unit 30 is warmed by the hot water supplied to the heater unit 30, warm air is blown into the room by a blower (not shown) to heat the room to a predetermined temperature, and the hot water supply line 31. Through the hot water circulation pipe (102) branched from the cold, the bottom of the warmer (100) is circulated as the cold, warmer (100) will be warmed to function as a warming. And the hot water circulating the cold, warmer 100 is delivered to the engine 10 and the radiator 11 through the hot water return line 32 to circulate the engine 10 and the heating device (B) again.

As described above, the vehicle cooling and warming device according to the present invention is installed between the cooling device and the heating device of the vehicle, and reduces energy waste by using some energy during cooling and heating, and according to the ambient temperature or environment. The food can be eaten cold or warm.
