By product certification reflects the strength of enterprises, the State Certification and Accreditation Administration Committee authorized the fan coil product can be certified unit is China Academy of Building Research, specifically by the environmental monitoring and control to optimize the implementation of research centers. Usually installed directly in the fan coil air-conditioned room, which served the state and worked will affect the quality of indoor air quality and noise levels. Therefore must be prepared to air filters, drip tray, coils, fans and other major components of routine maintenance worked to ensure that the normal role of horizontal concealed fan coil fan coil supplier, does not adversely affected. 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 equipment, its quality determines the effect 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 the water temperature and pressure normal horizontal concealed fan coil quality, while the unit inlet and outlet temperature difference is too small, should be suspected if the scale is too thick for the internal fan coil due to horizontal concealed fan coil for 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, if the plot had between coil and fins clear of dust, you can use compressed air to blow, if found to have the cracking or corrosion caused by fan coil leak, it is timely to trap with gas welding. Horizontal concealed fan coil quality | l Swiss Electromechanical | Shandong Horizontal concealed fan coil is provided by the Swiss liter HVAC Electrical Equipment Factory.
