Fan coil control scheme to use more local control, sub-control and temperature control of two simple. Simple controls: Use direct manual three-speed switch control three-speed fan and start and stop the conversion. Temperature control: STC series thermostat set temperature based on a comparison with the actual test temperature operation, automatic control STV series of electric two / three-way valve opening and closing; three-speed fan conversion. Or directly control the fan speed conversion and three stops, so as to achieve a constant temperature control system through the water or air flow. As of the end of the central air-conditioning fan coil device surface mounted fan coil unit price, its quality determines the effects of indoor air conditioning. Performance is mainly to protect send cold (heat) protection, air volume and value than the noise, the condensed water does not leak and electrical, sheet metal design is reasonable, and so on. Fan coil heat exchanger to maintain the unit in order to prevent the use of fan coil and into the outlet pipe scale, respond chilled water for softening; winter running hot water or prohibit the use of steam as a heat source, the temperature of the hot water used should not exceed 60 ℃. If the unit during operation of normal temperature and pressure of the water surface mounted fan coil retail, while the unit inlet and outlet temperature difference is too small, should be suspected if the scale is due to thick inner fan coil, fan coil inspection and cleaning . During the summer for the first time enabled fan coil units, cold water temperature should be controlled so that the temperature gradually fell designed to avoid immediately pass into the lower temperature of cold water leaving the cabinet and the inlet and outlet condensation dripping phenomenon. During operation, surface mounted fan coil, if dust accumulated significantly between coils and fins, can be loaded with compressed air to blow out how much money a fan coil units, fan coil units, if found to have caused the cracking or corrosion When the leak, it is timely to trap with gas welding. After the fan coil used for a period of time, it will accumulate on the fins and impeller dust and germs, when the dust reaches a certain thickness, fin cooling effect will be affected, leading to the room temperature is below standard, the other for long periods of cleaning fan coil will breed a variety of bacteria, these bacteria can cause disease on the human respiratory tract, it is recommended that the fan coil should be cleaned regularly. Cleaning meaning: 1, clear delivery, return air system, bacteria, dust, improve indoor air quality; 2, reducing drag VAV units, increase the heat exchange efficiency, increase air volume, energy saving; 3, regular fan coil pipe system maintenance and prolong the life of the unit; 4, lower operating costs, enhance asset value; cheapest surface mounted fan coil units, up Swiss electrical, Hunan surface mounted fan coil is provided by the Swiss liter HVAC Electrical Equipment Factory.
