Description

Automotive air conditioner equipment which uses thermoelectric semiconductor}

The present invention relates to a car air conditioner, and more particularly to a car air conditioner using a thermoelectric cooling thermoelectric semiconductor without using a refrigerant in order to maintain a comfortable indoor temperature of the car in the summer.

In general, a car air conditioner is a liquid that is easy to evaporate used in a refrigerant cycle, and a refrigerant is used, and in order to obtain low heat continuously by using a refrigerant, a liquid to gas, a gas to a liquid, and a liquid to gas are repeatedly changed. It is necessary to give it, and this is called internal cycle.

First, the refrigerant gas is sucked into the compressor from the evaporator and compressed to send a gas state of high temperature and high pressure (about 70 degrees, 15 kgf / cm 2) to the condenser. The refrigerant sent to the condenser is forcedly cooled by an electric fan or the like to liquefy. The liquefied refrigerant enters the receiver dryer to remove moisture and dust and then flows to the expansion valve. In the expansion valve, the high pressure liquid refrigerant rapidly expands, becomes a low temperature, low pressure mist refrigerant, and enters the evaporator.

The evaporator refrigerant takes heat from the surrounding air through the blower motor and the fan, becomes a gaseous refrigerant from the mist of the refrigerant, and is again sucked into the compressor. In this manner, the refrigerant is repeatedly circulated to cycle the cooling.

In general, a car's air conditioner needs an additional fuel consumption of about 15% to up to 20% depending on the change in driving speed. For example, if the 2000cc passenger car launched by the parent company runs at 2000rpm and the air conditioner is running, it needs to add more than 10 horsepower, which consumes more fuel and increases the emission of harmful gas.

5 is a graph showing a temperature difference due to a potential difference in the thermoelectric cooling semiconductor of the present invention. The thermoelectric semiconductor 110 has an N-type and a P-type, and the division is a carrier. , ), And in the N-type semiconductor, extra electrons (extra electrons) ) And holes in P-type semiconductors. ) Is called the carrier. Electrons can also play a role in transferring thermal energy. When carriers absorb heat at low temperatures and move to higher locations, the amount of heat transferred is proportional to the current of the carriers flowing through the circuit and the number of pairs of semiconductors (N-type and P-type semiconductors). In the superior thermoelectric semiconductor 110, carriers are easily moved in one direction with heat, but in the semiconductor made of bismuth telluride alloy with low thermal conductivity (1.5 W / mK), high heat is transferred. This naturally low conduction acts as a thermal barrier, mostly blocked by bismuth telluride. Therefore, it is possible to exhibit the thermoelectric cooling phenomenon by moving the heat in only one direction. These materials also have carriers with sufficient capacity to transfer large amounts of heat.

In the physical phenomenon in the low temperature region, the electrons transfer heat energy absorbed from the P-type semiconductor with low potential through the N-type semiconductor with high potential, thereby lowering the temperature on one side and increasing the temperature on the other side. At this time, the power supply (DC 12V) supplies energy for moving electrons through the system. In the high temperature portion, the energy transferred through the N-type semiconductor is released into the atmosphere by a heat sink to facilitate the flow of heat.

Thermoelectric cooler may be referred to as cooling by solid state reaction without fluid or gas flow. However, a large number of semiconductor pairs are electrically connected in series and thermally in parallel. Modules come in many varieties, depending on size and shape, input current, input voltage and heat pumping capacity.

Temperature of the hot side ( ) Is defined by external temperature and heat exchanger efficiency. These two temperatures ( Their difference in temperature () ) Is very important and needs to be measured accurately and shows the relative temperature of each part.

6 is a graph showing the temperature difference between the temperature of the low temperature generating member 160 in the state of blocking the air and the temperature of the low temperature generating member 160 and the cooling air in the state of introducing the air. Since the temperature change in the state in which the member 160 is insulated with the heat insulating member is a change in heat absorbed by the thermoelectric semiconductor 110, the second case 161 itself was used as a calorimeter for measuring the amount of change in calories. The principle is to measure the temperature by injecting cooling air into an insulated and enclosed space, but the measurement error will be very large due to cooling temperature leakage or hot heat coming from the outside. Therefore, this value was measured indirectly to avoid this, but it could reduce many errors. The meaning of each curve is as follows.

a-curve: The temperature change of the low temperature generating member 160 reduced with time by the thermoelectric semiconductor 110 in the insulated state by blocking the inflow of air and measured by a thermocouple (thermocouple).

b-curve: When the air is blown, the temperature of the low temperature generating member 160 changes with time, indicating that the low temperature generating member 160 obtains heat from the air and the temperature is increased.

c-curve: When the air is blown, the heat amount of air is absorbed by the low temperature generating member 160 to represent the temperature of the cooled air.

The temperature changed by blocking the air flowing in / out from the outside and absorbing heat per unit time of the second case 161 of the low temperature generating member 160 by the thermoelectric semiconductor 110 ( ) And indirectly calculated, the cooling efficiency was 21.7%.

7 is a graph showing the cooling efficiency delivered by the thermoelectric semiconductor per unit time of the present invention, the Q-curve will be described as follows.

In FIG. 6, since the data of the curve a can be obtained accurately, by setting the calorie function delivered by the thermoelectric semiconductor 110 per unit time using this, the integral value of this function is obtained by Origin5.0 program and the value is 1200 seconds. The total amount of heat transferred during is 33722.0 cal, and the thermoelectric semiconductor 110 has an efficiency of 21.7%.

Calories transferred per unit time = 33722.0 cal / 1200 sec

= 28.1 cal / sec

Energy supplied by power = 45.0 A × 12.0 V

= 540.0 Watt

= 540.0 Joule / sec

= 129.6cal / sec

Efficiency of thermoelectric semiconductors = (28.1 / 129.6) × 100

= 21.7%
