Operation of the air silk device dehumidifying operation control method First, as shown in FIG. 9, because the first and second steps (S1 to S13) are the same as the prior art *, only the other different steps will be described. In the second step, the microcomputer 5 is turned on 18 at the first specific time t1. Shrink the machine 10 and the outdoor fan 19, and rotate the indoor 18 at a specific speed of K, so that the dehumidification operation is performed. During the control of the dehumidification operation * the microcomputer 5 cooperates with the temperature sensor 2 to check (S14) The outlet temperature is divided into the detected temperature and the previously set minimum and maximum temperatures (s 1 5 | S | (Please read the precautions on the back before filling in this page)

Yc 'Y (丨.: _ B7 V. Description of the invention () S 1 6). (Please read the notes on the back before filling in this I) The result of the comparison (S 1 5). When the detected temperature is higher than or equal to the lowest temperature, the outdoor fan 19 will be turned on, and the second decompression device 1 The outlet temperature of 6 will decrease. When the detected temperature is lower than the minimum temperature, the outdoor fan 19 will turn off, and the outlet temperature of the second decompression device 16 will increase to the maximum temperature. In addition, according to the comparison result (S 1 6), when the detected temperature is higher than or equal to the highest temperature, the outdoor fan 19 will be turned on, the outlet temperature will be reduced to a certain degree, and when the detected temperature is low, At the highest temperature, the outdoor fan 19 will be turned off, and the outlet temperature of the second decompression device 16 will rise to the highest temperature. As shown in FIG. 7, in summer, in steps S 1 4 to ξ 19, when the maximum temperature is set to 3¾ and the minimum temperature is set to 1¾, if the outdoor temperature is 31 ° C and the indoor temperature is 27C, the microcomputer 5 will Perform a dehumidification operation and check the temperature of the outlet of the second decompression device 16 in cooperation with the temperature sensor 20. At the same time, it was printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs because the outlet temperature of the second decompression device was 1.52. As shown in Figure 4, the microcomputer 5 will compare the detected temperature of 1.5 ° C with the previously set minimum. The temperature is 1 υ and the maximum temperature is 3 Ό. As a result of the above comparison, because the detected temperature is higher than the previously set minimum and maximum temperatures, the microcomputer 5 will turn on the outdoor fan 19 and lower the outlet temperature of the second decompression device 16 to a certain degree. Then, during the rainy season, when the outdoor temperature is 2 5 ° C and the indoor temperature is the standard of this paper, the Chinese National Standard (CNS) A4 specification (210X297 mm) is printed. Known by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs — A7 Α Λ / Β 7 — ^ η · Ί --—- Five L · Fanxiu () 25t: Because the outlet temperature of the second decompression device 16 is -1, as shown in Figure 4, the microcomputer 5 will be more The detected temperature—1 2¾ is the same as the previously set minimum temperature of 1 υ and the maximum temperature of 3 * C. As a result of the comparison, because the detected temperature is lower than the previously set minimum and maximum temperatures, the microcomputer 5 will turn off the outdoor fan 19 and increase the outlet temperature of the second decompression device to a maximum temperature of 3 ° C. In addition, the microcomputer 5 will check whether the outlet temperature of the second decompression device has increased to 3 ° C, and compare the detected temperature 3 ° with the previously set minimum temperature of 1 ° C and the maximum temperature of 3 ° C. As a result of the above comparison, because the verified temperature is higher than the previously set minimum temperature and equal to the maximum temperature, the microcomputer 5 will turn on the outdoor fan 19 and lower the outlet temperature of the second decompression device to the minimum temperature. In other words, because the outlet temperature of the second decompression device can be controlled to rise to the highest temperature or drop to the lowest temperature, as shown in Figure 8, the temperature range of the outlet temperature of the second decompression device is controlled between 0 ° C ~ Between 10 ° C and irrespective of temperature changes between outdoor and indoor. As mentioned above, the air conditioner dehumidification operation control method is directly used to improve the dehumidification function. By controlling the evaporation temperature of an indoor heat exchanger, the evaporation temperature is between the previously set maximum / minimum temperature and indoor / outdoor. The temperature is irrelevant. Although for the purpose of illustration, the best embodiment of the present invention has been published, those skilled in the art will recognize that the present invention has various modifications, additions and substitutions without departing from the essence and scope of the present invention. -10- This paper size applies to China National Standard (CNS) 8-4 specification (210X297 mm) ------ „---- IO ------ Order ------ © I ( (Please read the notes on the back before filling out this page)
