The Advantages and Defect in Fan-coil air conditioning system

Fan-coil air conditioning system in air water is a main type of air conditioning system, to meet the high-rise building (hotels, office buildings, Department stores, hospitals, apartment buildings, etc) surrounding space sensible heat load fluctuations of needs and a wide range of applications. But everything has two sides, linyi air mesh concrete explanation in this respect.
wind machine disc tube of main advantages is: (1) layout flexible, the room can alone regulation temperature, room can’t when can off unit, not effects other room of using; (2) saves run costs, run costs and Dan Feng road system compared to about low 20–30%, than induced players low seen, and integrated investment costs General same, even slightly low, (3) can bear 80% of indoor load, and full air system comparison, saves space; (4 ) Unit stereotyped, standardized, easy to select an installation. The disadvantages are: (1) dispersed sets of unit, maintenance inconvenient; (2) transitional season cannot use the new wind, (3) small restricted air distribution units, suitable depth in 6m’s room, normally taken in conjunction with fresh air system.

Why does Air conditioning suddenly not cooling after running some days?

When this failure occurs, first turn on observation within the fan and check if the fan is working correctly outside; if the fan in indoor unit and outdoor unit is working properly, check the blower outlet with the condenser temperature is normal or not; handle export no cold air blowing out and the outdoor unit fan condenser without heat, the next check.
Power, open air conditioner outdoor machine machine shell, boot observation compressor running whether normal; if compressor not work, is power, with multimeter detection indoor machine temperature sensor resistance whether normal; if temperature sensor resistance normal, is detection indoor machine computer Board Shang of the plug received pieces whether exists loose or contact bad phenomenon; if no, is detection compressor all introduction feet winding resistance (as started winding end, and run winding end and public winding ends resistance) whether normal; if resistance disorders, Check compressor circuit if there is a problem; if the measured resistance value doesn’t match the standard value, describes compressor circuit faulty if measured resistance to normal, but check the compressor terminals between shell and no short circuit (resistance is infinite), describes compressor circuit properly, then the next check.
By air conditioner emergency key, will air conditioner forced boot, with pressure table detection pipeline system pressure whether normal; if pipeline system pressure normal, description not missing refrigeration agent, at this time again with pliers shaped ammeter detection air conditioner outdoor machine of running current whether normal; if running current partial big, is power with multimeter detection compressor of running capacitor whether internal open, if multimeter pointer has ups and downs dropped action, description capacitor no open, at this time is into – step judgment is compressor fault also is compressor started circuit of fault, Rebooting after the replacement of a model with the new capacitor and detect whether the operating current to normal if the normal running current indicates that the failure was caused by declining capacitance. Replacing attention compressor capacitor wiring capacitor pin ends of the wiring order, do not place the wiring connected to the wrong, preventing the expansion down.

Providing a cool and comfortable working environment for employees with air conditioner

Last year, after the cooler is installed in the workshop this year to continue to improve, making the workshop more cool!
Cool and comfortable working environment, you might think, Office, air conditioning here in this environment, but I want to say today is that we the divisions pipe production plant working environment.
For our suppliers, and most importantly, production workshop, so we first need to consider the workplace and working environment. Yearly as the weather gets warm, increase in machinery and equipment in the workshop, workshop in the summer temperature is relatively high. Above all, our welding workshop, welding is inherently need to be heated, plus shutian so that workplace temperatures even higher. Consider installing air-conditioning to cool down at the plant last year, but larger in each workshop, the use of air conditioning is not very ideal, after a friend introduced, cooler cooling works well, decisive decisions in each workshop in the factory installed air cooler, cooler cooling effect is indeed good, walked into the shop, make people feel liangsisi.
Cooler also has its disadvantages, however, only one cooling fan outlet, the cooling fan does not turn, where the wind blows and it was cold, and someplace where wind blows, over time, also is feeling the heat.
Plant this year heard that cooler can be adapted on each employee, according to an outlet, the wind, and every fan to cool breezes. So as soon as the factory cooler manufacturer, invested 20,000 yuan to refit the cooler.
Such a workshop a few outlets, each employee has a cold wind blows on the head, then hot outside, walked into the shop and feel temperatures suddenly dropped a lot.
