Abstract

The present invention relates to technology capable of enabling the operation of an air conditioner even in a state in which a vehicle is stopped and turned off. When a refrigerant is injected, the refrigerant is moved to a compressor (7) to be in a high-temperature and high-pressure liquefied state. The liquefied refrigerant is moved to an expansion valve and then, is connected from the expansion valve to an evaporator (6) but, at this point, the refrigerant is evaporated as the refrigerant flows from the expansion valve, which is a narrow copper tube, to a radiator beside the evaporator (6) and thus, the refrigerant takes heat from vicinity thereof. Surrounding cool air creates wind inward, and the spent refrigerant is re-sent to the compressor (7) to be circulated. Water (condensed water) produced as the refrigerant flows through the cold evaporator (6) is collected into a water container and pumped through a motor pump (10) and then, is atomized through an ultrasonic vibrator (9) and then, is supplied to a condenser (6) performing forcible air cooling such that a high-temperature and high-pressure gas refrigerant easily causes a phase change to a liquid refrigerant due to secondary evaporation heat. Accordingly, since a large amount of refrigerants have repetitive phase changes with low energy, high-efficiency and low-power technology for operating the compressor (7) less often and quickly liquefying refrigerants can be materialized.

Description

Low power vehicle air conditioning to operate when stationary}

The present invention is a low-power air-conditioning refrigeration technology (Low-power air conditioning refrigeration technology) that can effectively lower the temperature inside the vehicle, using a vehicle battery without stopping and starting, and It is a technical field related to air conditioners (air conditioners, air conditioners) for vehicles, and is not limited to vehicles, but is a technical field of all air conditioners (air conditioners, air conditioners) commonly used in daily life such as railways (trains) and household air conditioners. .

At present, air pollution such as fine dust cars, soot pollution, etc. has emerged as a serious problem, and the government is also considering ways to legislate to turn off the engine when waiting for a signal and turn off the vehicle. This is very painful, and if you are in a vehicle that has been closed for a long time in the summer, it is very dangerous to the human body, such as heatstroke, due to the high temperature inside. In order to solve such a problem, the present technology was studied. A typical car air conditioner consists of a ⑥ condenser, ⑥ evaporator, and expansion valve. When the refrigerant gas is injected, it moves to the ⑦ compressor (compressor) and becomes a liquefied state of high temperature and high pressure. The liquefied refrigerant moves to the expansion valve and is connected to the ⑥ evaporator from the expansion valve. At this time, when the refrigerant flows from the expansion valve, which is a narrow copper tube, to the ⑥ evaporator side radiator, it vaporizes and takes away the heat around it. By using this principle, the cool air around it is blown into the room, and the exhausted refrigerant is sent back to the compressor for circulation. This is the general principle of automotive air conditioning. However, the vehicle compressor (vehicle compressor) runs using the engine's torque. Therefore, the above steps are possible only when the engine is turned on (when the engine is running). To run the air conditioner without starting it, a car battery must be used. Therefore, a new technology of an air conditioner system capable of lowering power consumption in an air conditioner operation using a vehicle battery without starting is required, and in such a state, a battery management device is required to operate the air conditioner using a battery for a long time. This is to prevent shortening of life due to deep discharge. In general, the battery for deep discharge has a proper DOD (Depth of Discharge) value of 50%, but in the case of a car, it requires a lot of current when starting and is immediately charged by the generator after starting, and always has a voltage of 13.8V. Because it is maintained, long life can be maintained. For this reason, the technology for selecting and managing batteries must be accompanied in the air conditioner of the city.

In the present invention, among the components of the air conditioner ⑥

It was intended to newly devise a method to increase the efficiency of the condenser, and it is related to the configuration of the accompanying system. ⑥ Study on the shape of the condenser and the ability and speed of the cooling fan (FIG.-6) and the resulting increase in the cooling capacity of the evaporator. To solve the problem and to solve the problem of the battery management system used in the city air conditioner

first. Second, by supplying water (condensation water) generated in the process of passing through the cold ⑥ evaporator to the ⑤ water tank, pumping it using a 펌프motor pump, ⑨ atomizing it using an ultrasonic vibrator, and supplying it to the ⑥condenser that is forcibly air-cooled. The gaseous refrigerant of high temperature and pressure easily undergoes phase conversion into liquid refrigerant by the heat of vaporization. By doing so, a large amount of refrigerant has a phase change that is repeated with less energy, so it is possible to realize a high-efficiency low-power technology that turns the compressor (compressor) low and liquefies refrigerant quickly, so it operates for a long time while maintaining the deep discharge value at 50%. This is possible, and even if it is operated for a long time, the value of deep discharge is maintained, so the voltage of 13.8V is always maintained when recharging, so it can maintain a long life

second. ⑥ The speed of the cooling fan (Fig. 6) for efficiently cooling the condenser was measured and researched with an accurate rpm meter to select the speed as 3000 rpm. The cooling fan in a typical computer is about 1200 rpm. However, the cooling fan entering the computer (FIG.-6) is not in good power efficiency, although it does not consume much power. So, in order to find a speed that is faster than 1200 rpm and does not consume much power and can increase the cooling efficiency, the rpm was increased from 1200 rpm to measure temperature according to rpm. As a result of the measurement, it was selected as 3000 rpm, which is the most ideal speed to increase cooling efficiency without severe power consumption in cooling. Thus, it succeeded in lowering to the final goal of 150 watts or less. As a result of the experiment, it was measured from about 80W to about 100W. This resulted in better results than the final goal.

The effect of the present invention is that the air conditioner can be operated for a long time at low power by using a vehicle battery even when the engine is not turned on, and the battery can be operated for a long time without straining the battery. In addition, it has the effect of reducing electricity rates even if it is used for a long period of time as it is popularized for home and office use (inverter from vehicle DC power to AC).

The present invention has studied the low-power technology to reduce the severe power consumption, such as ⑦ compressor (vehicle compressor) in the process of operating the air conditioner using a vehicle battery even in the state that the start is not turned on. When the refrigerant gas is injected, it moves to the ⑦ compressor (compressor) to become liquefied at high temperature and high pressure, and the liquefied refrigerant moves to the expansion valve and is connected to the ⑥ evaporator at the expansion valve. When the refrigerant flows through the radiator, it vaporizes and takes away the heat around it. In accordance with this principle, the cool air around it cools to the room, and the exhausted refrigerant is sent back to the compressor to circulate. Collected and pumped using a 펌프motor pump, ⑨ atomized using an ultrasonic vibrator, and then forced to air-cooled ⑥by supplying it to a condenser. The phase was converted to liquid refrigerant, and the method for finding the rpm suitable for the present invention was measured rather than 1200 rpm by measuring and researching with an accurate rpm meter to obtain the speed of the cooling fan (FIG. 6) for efficiently cooling the condenser. In order to find a speed that is fast and does not consume much power and can increase cooling efficiency, temperature was measured according to rpm by increasing rpm from 1200 rpm, which is a typical fan speed, and as a result of measurement, if power consumption is not severe in cooling, Therefore, by selecting 3000rpm, which is the most ideal speed to increase the cooling efficiency, the overall cooling system is reduced in power. With the present invention, the effect of lowering the power is that the air conditioner can be operated for a long time at a low power by using a vehicle battery even when the start is not turned on, and the battery can be operated for a long time without straining the battery. In addition, it has the effect of reducing electricity rates even if it is used for a long period of time as it is popularized for home and office use (inverter from vehicle DC power supply to AC). In the future, it contributes to future automobile cooling systems such as electric vehicles and hydrogen fuel cell vehicles, and it is a product that can be used comfortably for a long time with low electricity bills by integrating cooling technology in the home.
