Xuzhou Sheng Erda Refrigeration Electrical Services Limited ☆ indoor unit issued a "blah" a small voice, whether this is due to a fault indoor fan motor speed change's sake, or because the air conditioner itself due to temperature changes, resulting in thermal expansion sound when shrink, all is normal. ☆ air conditioner use should pay attention to what the season before the use of air conditioning season, check the power cord is intact, is bad, the voltage is within the normal range. Should enable the selection of a dry weather Xuzhou air conditioning repair prices, the air conditioner operation mode set to "air" air conditioning repair, wind speed is "high", 4 hours of continuous operation, the electrical system to prevent moisture and avoid mildew inside the machine during operation flavor, such as smell blowing. Xuzhou 圣尔达 Refrigeration Electrical Services Ltd main components: (a) the compressor: The compressor is the heart of the air conditioner, it circulating pressure Freon gas. Due to the high pressure, high temperature refrigerant, easily liquefied state, after which the refrigerant is sent to the heat exchanger (condenser). Style: 1, piston (rarely used) 2, rotary (3P below) 6/8 page 3, scroll (2.5P-5P large function) single rotor is eccentric, will produce vibration, noise . Xuzhou symmetrical dual-rotor running air conditioning maintenance and fluoride, eccentric offset the impact of higher efficiency. (B), the heat exchanger: refrigerant when the heat exchange with the air, since the temperature difference between the refrigerant and the air, the refrigerant gasification or liquefaction: during cooling operation, the indoor unit heat exchanger is an evaporator, the heat exchanger of the outdoor unit a condenser; contrast during heating operation. Refrigerant obtained from the surrounding heat exchanger cools the surface of the rear fan blowing air through the heat exchanger and become air-conditioning, indoor air is blown. (Three), the throttle pressure reducer (capillary): through a heat exchanger to cool the liquid refrigerant liquefied due to a reduced pressure through a very fine pipes rather, from the high state to the low pressure state, is vaporized on entering the evaporator to provide possible. Xuzhou air conditioning maintenance and fluoride, air conditioning maintenance, refrigeration provided by Xuzhou Sheng Erda 圣尔达 Refrigeration Electrical Services Limited. Xuzhou 圣尔达 Refrigeration Electrical Services Limited (xzktw.com) strong, credible, in Xuzhou heat exchangers, refrigeration and air conditioning equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Sheng Erda refrigeration and you hand into the brilliant, for a better future!
