Description

Heating and cooling module {AIR CONDITIONING MODULE}

The present invention relates to a cooling and heating module, and more specifically, to a cooling and heating module that performs cooling and heating through one module and efficiently guides the flow of air inside an air conditioning case.

A vehicle air conditioning system is an interior part of a car that is installed to cool or heat the car's interior in summer or winter, or to remove frost from the windshield in rainy weather or winter to ensure the driver's front and rear visibility. These air conditioning devices are usually equipped with both a heating system and a cooling system, and cool, heat, or ventilate the interior of the vehicle by selectively introducing outside or inside air, heating or cooling the air, and then blowing it into the interior of the vehicle.

Figure 1 is a schematic diagram showing an example of a conventional vehicle air conditioning device. The conventional vehicle air conditioning device includes an air conditioning case ( 10) and; A blower 14 connected to the inlet of the air conditioning case 10 to blow outside air; An evaporator (E) and a heater core (H) provided inside the air conditioning case (10); It is formed to include a temperature door 15 that adjusts the opening degree of the cooled air passage and the heated air passage of the air conditioning case 10. In the conventional vehicle air conditioner configured as described above, when the cooling cycle is in operation, the temp door 15 opens the cooled air passage and simultaneously closes the heated air passage. Therefore, the air blown by the blower 14 passes through the evaporator (E), exchanges heat with the refrigerant flowing inside the evaporator (E), changes into cooled air, and then flows toward the cooled air passage and opens. The interior of the vehicle is cooled by being discharged into the interior of the vehicle through the vents 11, 12, and 13. In addition, when the heating cycle is activated, the temp door 15 closes the cooled air passage and simultaneously opens the heated air passage, so that the blown air flows through the heated air passage to the heater core (H). ), it exchanges heat with the coolant flowing inside the heater core (H), changes into heated air, and is discharged into the car interior through the open vents (11, 12, 13), thereby heating the car interior.

At this time, in order to supply cold refrigerant to the evaporator, as shown in FIG. 2, a compressor (1) that compresses and delivers the refrigerant and a condenser (1) that condenses the high-pressure refrigerant delivered from the compressor (1) ) (2), an expansion means (3) for throttling the refrigerant condensed and liquefied in the condenser (2), and heat exchange of the low-pressure liquid refrigerant squeezed by the expansion means (3) with air blown into the vehicle interior. An evaporator (E), which cools the air discharged into the room by absorbing heat due to the latent heat of evaporation of the refrigerant by evaporating it, is connected to the refrigerant pipe (5). Meanwhile, as described above, the evaporator (E) is provided inside the air conditioning case (10), the condenser (2) is located at the front of the vehicle to cool the refrigerant using running wind, and the compressor (1) must be located inside the engine room as it is driven by the engine drive belt. Accordingly, there is a problem in that the connection of the pipe 5 becomes complicated.

Meanwhile, a non-startup air conditioner for vehicles that is powered by a vehicle battery has been proposed so that vehicles such as trucks can be cooled even when the engine is not running, and this is shown in Figures 3 and 4. 3 and 4 are perspective and schematic diagrams showing a non-starting air conditioner for a vehicle, including first and second compressors 10a and 10b powered by the vehicle battery shown in FIGS. 3 and 4, and the first and second compressors 10a and 10b, respectively. First and second condensing units each having a condenser inlet (21) in communication with the first and second compressors (10a, 10b) through which the refrigerant flows, and a condenser outlet (22) so that the introduced refrigerant is discharged after exchanging heat with the outside air. A vortex condenser (20) composed of (20a, 20b), and first and second capillaries (30a, 30b) respectively communicating with the condenser outlets (22) formed in the first and second condensing portions (20a, 20b). ) and the first and second capillaries (30a, 30b), respectively, and after heat exchange with the evaporator inlet (41) through which the refrigerant is introduced and the introduced refrigerant is introduced, the first and second compressors (10a, 10b) ) and includes first and second evaporators 40a and 40b each having an evaporator outlet 42 so as to discharge the evaporator to the evaporator outlet 42, respectively.

However, the conventional air conditioning system for vehicles uses engine coolant for heating, and the non-starting air conditioning system for vehicles must install a separate heater in order to perform heating when the engine is not running.

Accordingly, there is a need for a device that can perform cooling and heating at the same time, can be miniaturized, and is easy to install on a vehicle. In particular, it provides appropriate cooling and heating even when the engine is stopped or the engine is not used. There is a need for a device that can perform this task.

That is, one refrigerant circulation line provided with a compressor, a heating heat exchanger 300, an expansion valve, and a cooling heat exchanger 200 may be installed inside the air conditioning case 100.

Here, the cooling heat exchanger 200 is preferably an evaporator, and the heating heat exchanger 300 is preferably a condenser.

The compressor is a component that sucks in and compresses gaseous refrigerant, and supplies high-temperature, high-pressure gaseous refrigerant to the heat exchanger 300 for heating. At this time, the compressor may be driven by receiving power from a power supply within the vehicle, a battery, and an external power source.

The heating heat exchanger (300, Condenser) exchanges heat with air for the high-temperature, high-pressure gaseous refrigerant discharged from the compressor, condenses it into a high-temperature, high-pressure liquid, and discharges it to an expansion means (not shown). At this time, the heating heat exchanger 300 acts as a heating source that heats the air passing through the heating heat exchanger 300 as the refrigerant condenses.

The heating heat exchanger 300 may be provided as a heat exchanger composed of a header provided in parallel at a certain distance apart and a tube whose both ends are fixed to the header to form a refrigerant flow path.

That is, the cold air that has passed through the intended cooling heat exchanger (200) is supplied to the interior of the vehicle to cool the vehicle, and the warm air that has passed through the unnecessary heating heat exchanger (300) is discharged to the exterior of the vehicle.

Figure 10 is a diagram showing the heating mode of the cooling and heating module according to an embodiment of the present invention.

As in the cooling mode, the cold air fan 240 and the warm air fan 340 rotate according to the operation of the cooling and heating module, and air flows into the cold air inlet 210 and the warm air inlet 310. At this time, the incoming air may be the vehicle's outdoor air or indoor air.

The air flowing into the cold air inlet 210 passes through the cooling heat exchanger 200 and flows as cold air. The first door 250 is arranged to be rotated upward to close the cold air discharge passage C1 and open the cold air discharge passage C2. Accordingly, the cold air passes through the cold air discharge passage (C2) and is discharged to the exterior of the vehicle through the cold air discharge port (230).
