By measuring Compliance is checked.

9 fever

In normal use, the temperature of the air conditioner and its surroundings should not be too high. Press GB 4706.32-2004 provisions 11.2 -11.9 Test conditions, by the temperature of the components and the surrounding environment was measured to determine their eligibility. 10 Leakage current and electric strength at operating temperature 10.1 at operating temperature, the air conditioner leakage current should not be too large, and should have sufficient electric strength. The air conditioner to work in the name of the steady state operating conditions. The air conditioner with auxiliary heater in heating conditions 1.06 times the rated voltage. Only electric heater heating the air conditioner in heating conditions 1.15 times the rated power input. Leakage current can be measured with a 13.2 GB 4706.1-2005 through provisions. Air conditioner fixed installation, the leakage current should be less than 2mA/kW rated power input. Accessible to the public air conditioner leak The maximum current should be less than 10mA, not accessible to the public of the air conditioner, the maximum leakage current should not exceed 30mA. 10.2 air conditioner electric strength test should be carried out, the insulation withstand 1min, frequency of 50Hz or 60Hz fundamental sine wave voltage, After the test off the power immediately. The test voltage is applied between the metallic parts of live parts and accessible parts covered with metal foil, the pair live parts and accessible There are class II constructions having intermediate metal between the member across the basic and supplementary insulation applied voltage. Test voltage. --- To bear safety extra-low voltage in normal use basic insulation to 500V --- For other basic insulation to 1000V --- For additional insulation to 2750V --- Reinforced insulation to 3750V The initial test, the applied voltage is not more than half the prescribed voltage value, and then quickly increased to full value. During the test, no breakdown occurs. Note. For this test of high voltage power supply short-circuit current Is and tripping current Ir, 13.3 GB 4706.1-2005 reference to the provisions of Table 5. 11 resistant to moisture 11.1 The air conditioner should be able to prevent water from entering the electrical components.

Then, drain pan to bear the continuous overflow, overflow rate to be adjusted to the amount of wind is 1m3/s when Corresponding overflow rate (about 17cm3/s), and to turn on all the fans. The test is carried out continuously 30min, or until the water from the air Machine discharging. 11.4 splash conducted leaching tests of the air conditioner, according to the provisions of GB 4706.32-2004 15.4 were tested. 12 Leakage current and electric strength 12.1 air conditioner leakage current should not be too large, and should have sufficient electric strength. By 12.2 and 12.3 of tests to check its Eligibility. 12.2 In the air conditioner at room temperature and does not carry out the test case of connecting the power supply. Leakage current test voltage of the air conditioner. The single-camera group, is 1.06 times the rated voltage; Three-phase units, is 1.06 times rated voltage, divided by three. Within 5s after application of the test voltage, leakage current is measured according to the provisions. Air conditioner fixed installation, the leakage current should be less than 2mA/kW rated power input, accessible to the public air conditioner leak The maximum current should be less than 10mA, not accessible to the public of the air conditioner, the maximum leakage current should not exceed 30mA. 12.3 After the leakage current test, the insulation is immediately subjected to 1min, frequency of 50Hz or 60Hz fundamental sine wave voltage, Test Test voltage is applied to the site and are shown in Table 2. Accessible parts of insulating material, covered with metal foil. The initial test, the applied voltage does not exceed half of the predetermined voltage value, and then quickly increased to full value. During the test the breakdown should not occur. The test shall be taken to avoid components of the electronic circuit damage. Table 2 Test voltage volts The test voltage is applied to the position Between live parts and accessible parts. --- During which only basic insulation isolated --- Therebetween with reinforced insulation isolated For double-insulated parts with only basic insulation and live parts separated And metal parts. --- Between live parts --- Between accessible parts Note. For this test of high voltage power supply short-circuit current Is and tripping current Ir, 13.3 GB 4706.1-2005 reference to the provisions of Table 5. 13 Overload protection of transformers and associated circuits When the air conditioner from a transformer power supply circuit should be used to meet the requirements of GB 19212.5 and GB 19212.7 transformer. meets the It may be required transformer short circuit or overload test. Otherwise, by applying the most unfavorable short circuit, or may occur in normal use of the Overload is checked. In this case the appliance to 1.06 times to 0.94 times the rated voltage or the most negative voltage power supply, the winding temperature Degree should not exceed the limits specified in Table 3. Table 3 Maximum winding temperature in degrees Celsius Type of protection Insulation material classification and temperature limits AEBFH 200 220 250 --- If the impedance protection --- If the protective device during the first hour of action to protect, max. --- The protective device after the first hour of action to protect, max. --- The protective device after the first hour of action to protect the arithmetic mean Abnormal operation 14 The design of the air conditioner should be avoided whenever possible fire hazard due to non-normal operation and malfunction caused damage safety or protection against electric shock Mechanical hazards.
