You have not had the remote control does not start? You can check the remote control, using the remote control at the ordinary radio central air conditioning, press any key on the remote control Xuzhou central air conditioning repair parts, are reflected in radio shows on the remote control is normal, the fault in the indoor unit control board or remote control receiver. Open the indoor unit cover and check the 220-volt and 12-volt input power and 5 volts are normal, start a manual air-conditioning, air conditioning can start functioning normally, indicating that the control board is no problem, fault location on the remote control receiver components, and remote cause is not accepted. After which requires professional maintenance personnel will be cut off 103 capacitor directly or replace the display panel, the air conditioner has been operating normally. The cause of many of the remote control signal is not received, in addition to the capacitor leakage, but no member Weld also cause does not receive, in addition to air-conditioned environment of the remote control receiving a great impact, when humidity is high, condensate in the remote display panel back welding Point feet and legs condensation, mold circuit boards, electrical insulation, resulting in leakage between the pad remote control does not boot or remote control malfunction, the transformation of central air-conditioning cleaning circuit boards Xuzhou, after treatment with a hair dryer at a remote display panel back welding layer of glass, plastic, remote control can be received normally. Central air conditioning system is driven by a series of fluid flow heat exchangers of various types of sports equipment (such as fan coil units, evaporator, condenser, and an intermediate heat exchanger, etc.) and connecting pipes of various devices (such as ducts, pipes and refrigerant pipes) and the valve member of the composition. The system can be divided into the following five general cycle: (1) the indoor air circulation; (2) cold water circulation; (3) circulating refrigerant; (4) cooling water circulation; (5) outdoor air circulation. Overall, constitute a central air conditioning system equipment and machinery are mainly two kinds of heat exchangers and fluid machinery. Heat as high and low temperatures two working fluid energy exchange equipment. When the heat is not good for any one group, will increase system power consumption rate (kW / RT), not the system increases power consumption is freezing ability. Fluid machinery is working fluid cycle power plant to promote Xuzhou old central air conditioning recovery, the power consumption W = QHh / η. How much power consumption during operation depends on the number h, delivery of the working fluid flow rate Q, the working fluid circulation desired lift H and efficiency η, to reduce any of them, can save energy.
