Description of Invention (is) When operating in the high mode, the air in the cabin is sucked in through the inlet 9 and cooled when passing through the heat exchanger 7. The air cooled by the heat exchanger 7 blows forward from the outlet 11e to the first duct 2. The cold wind flowing forward in the first duct 2 is then blown into the region I by the front half of the first duct 2 in the outlet. When the temperature of the area I is cooled below the second reference level due to the cold air blowing from the outlet, as described above, this state will be detected by the first temperature sensor 29, and the control circuit 35 will be turned off The first high mode relay 3 9 and the relay switch 3 9 a are also turned off. Then, the motor 1 1 7 b is powered by the resistor 46 and switched to a low rotation speed, so that the forward blower 11 is switched to the low mode with a low blowing rate. When the temperature of the area I is cooled below the first reference level due to the low mode operation of the forward blower 11, this state will be detected by the first temperature sensor 29, and the control circuit 35 is turned off The first low mode relay 3 8 and the relay switch 3 8 a are also turned off. Therefore, the operation of the first cooling unit 5 before the blower 11 is interrupted. When the first temperature sensor 29 again detects a temperature higher than the first reference level or the second reference level, the forward blower 11 then operates in the low mode or high mode, as described above . When the temperature of the area II is higher than the first reference level or the second reference level, similar to the foregoing, the second low mode relay 40 or the second low mode relay 40 and the second high mode relay 4 1 are turned on , And the first cooling unit 5 is then operated in the low mode or the high mode to the blower 12. When the temperature of the area II is cooled below the first reference level due to the cold air blown from the second half of the outlet of the first duct 5, the operation of the backward blower 12 is interrupted.

V. Invention Description (19) Similarly, when the temperature in areas III and IV is higher than the first reference level or the second reference level, the first The second cooling unit 6 operates the forward blower 11 and the backward blower 12 in the low mode or the high mode according to the temperatures detected by the third temperature sensor 31 and the fourth temperature sensor 32. When the area III and When the temperature of the IV is cooled below the first reference level due to the cold air blown from the first half and the second half of the outlet of the second duct 6, the operation of the second cooling unit 6 before the blower 11 and the back blower 12 is interrupted. Thus, according to the foregoing implementation For example, the first and second cooling units 5 and 6 are arranged in the longitudinal middle of the first and second ducts 2 and 3, and the first and second cooling units 5 and 6 are equipped with multiple blowers, that is, forward To the hair dryers 11 and 11 before blowing and to the hair dryer 1 after blowing backwards 2 and 12 are shared with each other, and the operation of these forward and backward blowers 11 and 11, and 1 2 and 1 2 are controlled according to the temperatures detected by the first to fourth temperature sensors 2 9 to 3 2 Operation. In the two sets of cooling units, it is not necessary to use the blowing direction switching damper to cool the areas I to IV separately, so the cost can be reduced. In addition, in the foregoing embodiment, the first and second cooling units 5 and 6 are series Arranged in the longitudinal central portion of the first and second ducts 2 and 3, and the first and second cooling units 5 and 6 are provided with the same number of forward blowers 11 and 11 and backward blowers 12 and 12. Each area I to IV The body is the same, so that it has the same cooling capacity. Therefore, the first and second cooling units 5 and 6 are longitudinally symmetrical, and their structures can be the same.

Description of the invention (20) The longitudinal central part of the second catheter 2 and 3, which can suppress the first and The rate of temperature rise of the cold air in the second duct. In detail, since the first and second ducts are arranged on the ceiling of the bus compartment, the heat gradually generated by the sun on the bus roof prevents the cold air from flowing through the first and second ducts 2 and 3. However, when the first and second cooling units 5 and 6 are arranged at the longitudinal center of the first and second ducts 2 and 3, from the first and second cooling units 5 and 6 to the first and second ducts 2 and 3 The length of the two longitudinal ends of 3 can be shortened, and the temperature rise rate of cold wind is reduced. Fig. 19A shows the temperature measurement results when cold wind passes through the ducts D 1 and D 2, wherein the cooling units C 1 and C 2 are arranged behind the ducts D 1 and D 2: Fig. 19B shows the aforementioned embodiment of the present invention. It can be clearly seen from FIGS. 19A and 19B that the temperature rise rate of the present invention is low, so that the M domain near the front and rear ends of the first and second ducts 2 and 3 can also be cooled to a satisfactory degree. Printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs (please read the precautions on the back and then fill in W page) In addition, according to the present invention, it is used to detect the first to fourth temperatures for each temperature in the range of 1 to IV The sensors 29 to 32 are arranged at corresponding positions on the front and rear ends of the first and second ducts 2 and 3. Therefore, the areas detected by the first to fourth temperature sensors 29 to 32 are cooled by the cold wind blown from the front and rear outlets, and the cold wind is the one that receives the longest sunlight exposure. Therefore, the lack of cooling efficiency in the area can be avoided. Furthermore, according to the present invention, the blowing rates of the forward blowers 11 and 11 and the backward blowers 12 and 12 can be changed according to the temperature of each zone I to IV (high or low mode). Therefore, of the regions I to IV, the regions with higher temperature receive more cold wind, and the regions with lower temperature receive less cold wind. In this way, the blower can be adapted to the Chinese National Standard (CNS) Λ4 specification (2ΙΟ'χ 297mm) at the appropriate cold air blowing rate according to the cooling capacity requirements. -23 3 ^ 7721 _ ^ __ V. Invention description (21) Running. The control circuit 35 is a decision mechanism for determining the required cooling capacity (cold air blowing rate) of each area I to IV according to the detected temperature of the temperature sensors 29 to 32. Controlled by the first to fourth low mode relays 3 8, 4, 0, 4 2 and 4 4 and the first to fourth high mode relays 3 9, 4, 1 4, 4 3 and 4 5 which are opened and closed by the control circuit 35 Motor 1 1 7b to 1 2 0 b speed mechanism. The speed control mechanism is not limited to dividing the speed into two levels of high and low modes, but can be changed to divide the speed control into three or more levels, or stepless speed control. The first and second forward blowers 11 and 11 and the first and second backward blowers 12 and 12 are each constituted by a blower. The present invention is not limited to applications in buses: the air conditioner of the present invention can be applied to general vehicles that divide the cabin into four individual cooling zones. Employee Co-operative Indun, Central Bureau of Standards, Ministry of Economic Affairs (please read the precautions on the back before filling out this page) The inlet c and 1 2 c of the single-side suction centrifugal hair dryer 1 1 and 1 2 are directly connected to the back surface of the toe board 1 0 Inside the air outlet 10 b, so that the wind direction can directly rotate 90 degrees in the back surface of the toe board 10 (ie, from the width direction C4 to the longitudinal directions A and B), so the branch duct in the conventional technology may not be needed Or connect the catheter. Therefore, in the factory, the cooling units 5 and 6 composed of the heat exchanger 7, the plate 10, the blowers 11 and 12, and the suction plate 16 can be combined in advance, and these units can be easily installed in a kit On the vehicle. Furthermore, the cooling unit 5 or 6 is assembled into a small structure that can be completely accommodated in the cold air duct 2 or 3. Therefore, the cooling unit 5 or 6 does not protrude, so that the appearance of the interior of the vehicle cabin can be improved and the space above the passenger's head can be increased. This paper scale is applicable to the Chinese National Standard (CNS) Λ4 specification (210X297mm) A7 B7 5. Description of the invention (22) In addition, since the cooling unit 5 or 6 is completely accommodated in the cold air duct 2 or 3, the whole is placed in a cold air environment Therefore, the temperature difference between the inside and outside of the toeboard can be reduced. Therefore, the gimmick board 10 can be prevented from condensing, so there is no need to provide a thermal insulation mechanism for it. The part that needs to be provided with thermal insulation mechanism can be limited to the temperature-sensitive barrier part of the expansion valve. Also, depending on the operation of the air conditioner (such as the humidity of the air sucked in or the temperature difference between the inside and outside of the gimmick plate 10, etc.), condensate may be generated on the outer surface of the gimmick plate 10. In this case, since the rising edge of the drip plate 16 is located on the side of the outer surface of the gimmick plate 10, if condensed water is generated on the outer surface of the gimmick plate 10, it can be accepted by the drip plate 16. In addition, the cold wind blown by the blower 11 or 12 can be immediately pushed into the cold wind duct 2 or 3 located on the side of the vehicle, causing its rapid expansion and deceleration. Therefore, the dynamic pressure at the outlet of the blower (that is, the pressure P determined by the outlet wind speed) can be converted into a static pressure to make the wind blown by the cold air outlet 4 uniform.
