Description

Vehicle air conditioning system with the engine turned off}

The present invention relates to a non-starting vehicle air conditioning system.

Typically, a vehicle's air conditioning system includes an air conditioner to lower indoor temperature or dehumidify. Similar to general air conditioners in buildings, air conditioners in vehicles are equipped with a compressor, condenser, evaporator, and expansion valve. However, there is a condenser on the radiator instead of the outdoor unit, and this is cooled by a cooling fan. Generally, the compressor is installed to be operated by the output of the engine, and accordingly, when the engine is turned off, the compressor and air conditioning system are also turned off.

With the spread of leisure culture using vehicles, the use of vehicles at destinations such as camping sites or while parked increases, and the need to use air conditioners is also high. However, using only the air conditioner without running the vehicle with the engine on not only reduces energy efficiency, but also causes air and noise pollution, which is against environmental protection. Additionally, there are concerns about the possibility of safety accidents such as fire due to engine overheating. Accordingly, there is a demand for a vehicle air conditioning system that can be used without turning on the vehicle engine.

Referring to Figures 1 to 3, the non-startup vehicle air conditioning system according to the present invention includes a vehicle air conditioner unit 100, a sub air conditioner unit 200, a control unit 300, and a control unit 400.

First, the vehicle air conditioner unit 100 is constructed and operates in the same configuration as the air conditioner provided in a conventional vehicle.

The vehicle is equipped with an engine 110, a generator 120, and a vehicle battery unit 130, and is equipped with a number of configurations according to the air conditioner. Hereinafter, the operational relationship and structural description of the components related to the vehicle air conditioner according to the compressor, condenser, cooling fan, evaporator, and blow fan 180 will be briefly described since it is already known technology.

The generator 120 is driven by the vehicle engine 110.

The vehicle battery unit 130 is connected to the generator 120, is charged with power generated through the generator 120, and supplies the charged power when the generator 120 is driven.

The vehicle compressor 140 is operated by the vehicle engine 110.

The vehicle condenser 150 receives vehicle refrigerant from the vehicle compressor 140.

The vehicle cooling fan 160 is provided on one side of the vehicle condenser 150 to cool the vehicle condenser 150.

At this time, the engine 110, generator 120, and vehicle cooling fan 160 are connected by a belt and driven together from the time the vehicle is turned on until the vehicle is turned off. In some vehicles, the vehicle cooling fan 160 is driven even when the engine is turned off, so the above-described content is not limited.

The vehicle evaporator 170 receives vehicle refrigerant from the vehicle condenser 150 and delivers it to the vehicle compressor 140.

Additionally, depending on the vehicle, the vehicle evaporator 170 may be comprised of multiple vehicles. At this time, when the vehicle refrigerant is delivered from the vehicle condenser 150, it may be branched and delivered. Additionally, when branching vehicle refrigerant to a plurality of vehicle evaporators 170, branching can be controlled using a valve.

The blow fan 180 is provided on one side of the vehicle evaporator 170.

The case 190 has a vehicle evaporator 170 and a blow fan 180 installed inside, and an inlet 191 through which air flows into the blow fan 180 on one side and the vehicle evaporator 170 through which the introduced air flows. An outlet 192 is formed through which cold air is discharged.

Additionally, a heater may be provided inside the case 190, a number of doors may be formed to separate the heater and the vehicle evaporator 170, and various passages may be formed depending on the opening and closing of the doors. Additionally, a vehicle refrigerant line through which vehicle refrigerant, which is delivered to the vehicle evaporator 170 and delivered to the vehicle compressor 140, moves may be provided inside the case 190.

Here, the non-starting vehicle air conditioner system of the present invention is achieved by adding a sub air conditioner unit 200 to the vehicle air conditioner unit 100 and controlling it together with the vehicle air conditioner unit 100.

The sub-air conditioner unit 200 includes a sub-evaporator 210, a sub-compressor 220, a sub-condenser 230, a sub-cooling fan 240, and a sub-battery unit 250.

That is, the sub-evaporator 210 is provided inside the case 190 with one side inserted into the through hole 193 and the other side in close contact with the inlet of the through hole 193.

In other words, a through hole 193 is formed in the case 190 of a conventional vehicle, and the sub-evaporator 210 is inserted between the vehicle evaporator 170 and the blow fan 180 to form a through hole 193 inside the case 190. Formed so that it can be prepared. Accordingly, the sub-evaporator 210 can be inserted into the through-hole 193 to face the vehicle evaporator 170.

At this time, compressed air passing through the blow fan 180 may pass through the sub-evaporator 210 and the vehicle evaporator 170.

Meanwhile, the sub-evaporator 210 may be installed on one side and the other side of the vehicle evaporator 170. Here, it is desirable for the sub-evaporator 210 to be installed inside the case 190 without interfering with the vehicle refrigerant line connected to the vehicle evaporator 170 and other conventional vehicle accessories such as heater modules and doors. In addition, a door and a flow path are formed in the inner space of the case 190 where the vehicle evaporator 170 is installed, so that the sub case has the same area as the vehicle evaporator 170 and faces the space where the vehicle evaporator 170 is installed. Since it is difficult to install the evaporator 210, it is preferable to install the sub-evaporator 210 in an installation space formed to allow air to pass between the blow fan 180 and the vehicle evaporator 170 or vehicle accessories.

Accordingly, since the above-described vehicle accessories are not located between the vehicle evaporator 170 and the blow fan 180, the sub-evaporator 210 is provided in the installation space between the blow fan 180 and the vehicle evaporator 170. desirable.

In addition, the case 190 is further formed with a blocking hole 194 penetrating between the through hole 193 and the outer edge of the case 190.

At this time, the sub air conditioner unit 200 supplies cold air to the interior of the vehicle when the engine is not started, and a cooling area of 1 to 20 m2 is sufficient. Because of this, each configuration can be formed consistently according to the cooling area of the sub-air conditioner 200. In particular, the area of the sub-evaporator 210 can be formed to be smaller than the area of the vehicle evaporator 170, but It is preferable that the sub-evaporator 210 be formed to have a minimum area so as to facilitate installation of the sub-evaporator 210 in the internal installation space of the case 190.

Accordingly, the installation space of the case 190 where the sub-evaporator 210 can be installed may be different for each vehicle. Here, when installing the sub-evaporator 210 having a vertical width smaller than the vertical width of the installation space, it is necessary to block the gap formed at the top or bottom of the sub-evaporator 210.

That is, since a gap may occur between the upper or lower part of the sub-evaporator 210 and the inner surface of the case 190, a blocking hole 194 is further formed to install a blocking portion 500 to block this gap. will be.

The blocking portion 500 is inserted into the blocking hole 194 to block the gap formed between the inner surface of the case 190 and the sub-evaporator 210, and directs the air introduced into the blow fan 180 to the sub-evaporator 210. ) to pass.

On the other hand, if the vertical width of the sub-evaporator 210 and the vertical width of the installation space are the same, the formation of the blocking hole 194 and the provision of the blocking portion 500 are not necessary, but the sub-evaporator 210 of the present invention can be used in various vehicles. In order for it to be applied, it is desirable to have it formed to the minimum size, and in other vehicles, the gap is blocked through the blocking hole 194 and the blocking part 500 to allow as much air as possible to pass through the sub-evaporator 210. It is desirable to be able to do so.

In addition, the through hole 193 and the blocking hole 194 are between the blow fan 180 and the vehicle evaporator 170 to prevent it from contacting vehicle accessories already installed inside the case 190 when the blocking portion 500 is inserted. It is desirable to be formed in .

It is formed at an angle to partition. At this time, the blocking hole 194 is preferably formed to be inclined with the blocking portion 500 inserted therein so that the air supplied to the blow fan 180 can prevent eddy currents and be concentrated in the sub-evaporator 210. In other words, when the blocker is inserted, not only does the air move along the inclined blocker and concentrate in the sub-evaporator, but also a smooth air flow is achieved because eddy currents do not occur in the space between the sub-evaporator and the blow fan.

Additionally, the fitting hole is formed in the shape of a long hole inserted into the front and rear of the sub-evaporator 210.

In addition, the opening hole is formed shorter than the minor axis length of the fitting hole, and the opening width becomes narrower toward the outer surface of the sub-evaporator 210.
