According to the relevant personnel, many people consult their own heating and heat sink or air conditioning "strike" not to make hot? Reporters to sort out some of the more typical case, the heating professionals for diagnosis.
Heating problem
Upstairs to enjoy the blessing of heating downstairs
"My warm with two heating seasons last week, opening of the boiler, the nearly eight hours ground still put up the 'cold' face. The home of the elderly are frozen, it is urgent." Ms. flowers home court to reporters about reixing. On Saturday, a reporter with the Nanjing Depp heating equipment company engineer Yu Kai to take home to see what ms.. Ms. Hua's boiler is a German VAILLANT, working condition is normal, because the kitchen and toilet water supply flow. "Preliminary determination of the problem in the pipeline or laying in the ground floor of the insulation." Yu Kai said that the open most of the day, north of the second bedroom temperature is not. This is because at that time the construction unit of the design personnel not according to the housing structure, toward the selection of different heat loads. Such as the use of the same cloth tube, pipe loop is too long, tube spacing is too large, it may design heat load is less than the room the actual heating load, resulting in the north room is not hot. The flower lady's restaurant is close to the boiler, it should be the fastest, but the actual effect is not obvious. Yu Kai analysis believes that this is due to the unreasonable charge line, resulting in inadequate water flow. Then a pedestrian came downstairs tenants, the amount of the living room ceiling temperature, found to reach 21. That is to say, most of the hot gas to the house to go downstairs, it is because of the poor quality of the ground insulation materials and radiation layer." Yu Kai pointed out that the situation is more common, like the lady in the home, it is difficult to repair. So to remind the public, the installation of heating boiler is a good one, to find a regular strength of the heating companies to service is also very important.
Heat sink problem
"Small horse drawn carts" heat does not come
The rose garden Longfeng Mr. Wan reflect his home in October of this year to be put on fins, found a few days ago when they opened up, restaurant, bathroom and study as warm as toast, area large two bedroom and living room don't do. Looking for HVAC companies, was informed that the use of the method is not caused, but the method is not where to say it does not come out. Nanjing Zhijia cooling and heating equipment company responsible person Shao Disha that room with a large area of the radiator heat is insufficient, mostly at that time, the design of heat supply and heating area does not match, the formation of "small horse drawn carts". Also if the pipe laying before not carefully cleaning the mess in pipe, resulting in blocking the pipeline, or individual construction personnel quality is low and rough handling, the pipe bending die, flattening phenomenon resulting in poor flow will lead to the emergence of this situation. In addition, if the various pipeline length difference is too big, water inlet pipe, a return pipe and a water separator. The corresponding interface connected in reverse, and the water temperature in the boiler burned high again, the terminal will be no response. Shao Disha said radiator exhaust valve failure, in the heat radiating fins are accumulated a large amount of air, will not cause thermal heating, which is "gas plug" phenomenon. This situation can be resolved by the user, the air exhaust device to open the exhaust pipe in the air, after closing the valve, the system can be a period of time to return to normal. Don't listen to some small companies that overhaul".
Air conditioning problem
Maintenance is not good at low temperature on strike again"
The question of whether the air conditioner is slow or not hot, and the readers are asked a lot of questions. "As usual as long as 5-8 minutes the entire room on the heating up, and now, and so on for more than half an hour, and only a little hot." "Air conditioning in the summer is also used well, how to do not have a winter? Is the air-conditioning is bad?" On these issues, chairman of Jiangsu refrigeration industry association Wang Gaoshi analysis said, air conditioning and heating effect is not good, general reason is air filtering net is too much dust, indoor and outdoor machine of air vents are blockage caused. Filtering net effect is that the adsorption of the dust in the air, if the accumulation of too much dust is not timely cleaning will block air circulation, resulting in the outlet of a reduction in the amount, machine of heat cannot be air flow in time to take out, resulting in of quantity of heat is insufficient. In this case, it is only necessary to remove the air filter regularly cleaned, you can return to normal.
At present, the citizens of Nanjing mostly used in heat pump or pump and auxiliary electric heating type air conditioning, the working principle of the two air conditioning are Freon evaporation absorb heat from the outdoor air, when the outdoor temperature is low, and Freon evaporation temperature difference is small, heat transfer effect becomes worse and the hot wind is less.
