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 freezing phenomenon can be, but is prone to uneven temperature Column fan coil price, 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, 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 Column fan coil wholesale 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 water systems in parallel with) a combination of running and small circulation pump that water system pipe fan coil water temperature is not lower than 5 ℃ Column fan coil units, ensure antifreeze. To ensure that the water within the system 5 ℃ Column fan coil company, 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. 1, the cold water inlet temperature of fan coil units should not be less than 5 ℃, otherwise it may cause condensation unit; inlet water temperature should not exceed 80 ℃ (commonly 60 ℃), or it may cause the unit heat exchanger brass corrosion. 2, the operating ambient temperature is recommended when the cooling fan coil units: 16 ~ 36 ℃, when the heat: 10 ~ 30 ℃; relative humidity ≤90%. 3, fan coil units only as a comfort air conditioning use, not for special occasions. 4. Do not fan coil installed in areas where corrosive gases Column fan coil pictures, rose Swiss electrical, Anhui Column fan coil is provided by the Swiss liter HVAC Electrical Equipment Factory.
