Using high-quality galvanized chassis fan coil air conditioning fan coil cash on delivery, condensate tray molding process using one piece, no welds, joints, insulation materials meet the fire code is integrally connected to the fan coil small water dish : lightweight body design is easy to install sewer lines and air-conditioning fan coil, about to take over and return air mode can be converted at any time to match scene unit can be installed in any space fan coil efficiency high places: expanding technology of advanced air-conditioning fan coil tube model is complete, to ensure close contact brass and aluminum heat exchanger, the heat transfer performance; low noise fan coil: rational fan and airflow design, high-quality sound-absorbing insulation, noise and the unit below the national standard 1 -3dB (A); fan coil Low energy consumption: a reasonable match fan and heat exchanger, Three adjustable air flow, the fan power most provinces of central air conditioning fan coil terminal equipment is widely used in the purchase, specification stands for central air conditioning fan coil units. There are deactivated when the fan coil low temperature in winter time, how antifreeze Method One: 1. Central air conditioning design issues should be considered when winterizing antifreeze is recommended to use the means of hot water, do not support the use of steam and electric heating. Steam antifreeze can be, but is prone to the phenomenon of uneven temperature, fan coil upper temperature is relatively high, the bottom has begun to freeze. Does not support the use of electric heating, electric heating prone to danger first, then electric heating more cost electricity, not energy, the control should be careful not to single fan coil switch, should all control. 2. If you do not use the fan coil in winter, it is recommended: a. The fan coil inside the water all let go, b. In the water supply and return water plus Blind, c. Use compressed air (according to the size of the fan coil air blowing time decision) d. Add antifreeze to the fan coil, not necessarily fill the latest air conditioning fan coil, but to ensure that the fan coil is antifreeze liquid fully diluted. e. Plus circulation pump design. Method two: the design of the chilled water system in parallel a small capacity circulating pump. 1. If the system is deactivated in winter, but there is a heat source, you can switch to the fan coil heat water system, so small circulation pump is running. 2. No heat, you can set an electric heater (shell and tube and water systems in parallel) in combination with small circulation pump is running, so that the water system pipe fan coil water temperature not lower than 5 ℃, guarantee antifreeze. To ensure that the water within the system 5 ℃, electric heating power is not too large, the operating cost is not high, than turn on the water, add antifreeze and other methods are reliable. The above method for reference. Air conditioning fan coil cash sufficient electromechanical _ _ Swiss liter by liter Hunan fan coil air conditioning HVAC Swiss mechanical and electrical plant.
