Haier inverter air conditioner KFR-120LW / K2SDY poor heating effect Analysis:-site inspection of the air conditioning and heating can, but remote control can not control the wind speed, the outlet temperature reached 35 degrees, the air conditioning mode conversion Xuzhou try modifying telephone central air conditioning, refrigeration time Winds can be high. Low adjustment, it is possible to determine the fan motor is good. You can doubt the indoor pipe temperature sensor is broken. Results: Replace the indoor pipe temperature sensor, the test machine is normal. Experience: temperature sensor plays a very important role in the air conditioning, it can cause a lot of trouble Xuzhou poor central air conditioning maintenance, in this case, the air conditioning and heating, due to anti-cold air function, room temperature sensor feel 25 degrees wind turbine operation above a low, reaching more than 30 degrees to set the wind speed run, more than find fault first wind speed is low, and the air temperature is high, it is necessary to check the fan is normal. When determining the normal fan, you can not check suspect temperature sensor, the fan does not cause the remote control to set the wind speed in order to operate, so replace the inner tube temperature sensor. In the fixed-frequency air in suspected bad sensor can be placed in a forced air-conditioning refrigeration state, such as air conditioners can be operated, and the current normal, generally considered bad sensor. Q: The biggest difference with ordinary air-conditioning inverter air conditioner where? A: inverter air conditioner has several key features: First, the special inverter device, which is what we usually refer to the inverter, which includes rectification, filtering, power output, electromagnetic compatibility control unit. Second, the inverter compressor central air conditioning, it's the ordinary fixed speed motor with the motor of the compressor different, mainly three-phase induction motor or permanent magnet motor, which is what we usually refer to AC inverter compressor DC inverter compressor. Third, the special ability to change the design of inverter air heating and cooling systems. Fourth, the advanced performance of the central processor, ensure inverter air conditioner according to the user's needs, environmental conditions, the state of the air conditioner automatically adjust their output capacity to ensure that the inverter air conditioner can be comfortable, energy-efficient, reliable operation. Those who meet the above inverter air conditioner a few key features can be said to be true of inverter air conditioner. As for the inverter air conditioner excellent performance parameters or not is determined by the manufacturers design level. No basic knowledge of inverter air conditioner inverter air conditioner repair people would say is not only using the inverter compressor and the corresponding control unit has the advantage of home air-conditioning independent economy. The main advantages: 1. Temperature control: Ordinary household air conditioner can adjust the air temperature, but due to structural limitations, the small air volume, air temperature and the temperature difference between the indoor air, so that the indoor temperature distribution is not uniform, poor comfort; and large central air-conditioned, the temperature difference is small, the temperature distribution, the comfort is good. And air conditioning of the kitchen can be achieved. 2, adjust the humidity: household air-conditioners are dehumidifiers, run over time, indoor air dry, skin discomfort. The Beijing area dry climate, central air can be pumped into the fresh air add humidity. 3, the suspension is filtered: dust suspended in the air is Xuzhou Hitachi central air conditioning sales, central air conditioning system, one of the bad signs with supply and return air system, a large number of cold (warm) air blown from the outlet, turn Each bedroom and living room air sucked back from the return air, return air built with high-efficiency filters, can filter dust. 4, increase fresh air: each person needs 15-18 cubic meters of fresh air per hour, in order to ensure health. Now widely used in household air-conditioner only air temperature regulator, and to improve the air humidity, oxygen content and other indicators of powerlessness. With the increase of the air conditioner running time, indoor air gradually becomes cloudy, easily lead to upper respiratory infections. Filtration and purification of the above relying solely on measures of negative ions and so it is difficult to fundamental change. The most effective way to solve the problem is to replace the fresh air. Home central air conditioning with fresh air replenishing device can be introduced into new wind. 5, increase the aesthetics of the space-saving: home central air-conditioning in a unique position to save space and increase the aesthetics aspect. Now people are no longer confined to the room of requirements Ershiyiting, Sanshiyiting room, split-level room after another and so on. If the first with split air conditioning, more than three out of the machine must be installed, while apartments have outdoor unit installation location restrictions, not beautiful. At the same time, one in each room to hang the indoor unit is not the best looking, and central air conditioning only one outdoor unit, and can choose a variety of styles outlet, combined with the ceiling design, mounted on the roof. Each outlet can be individually controlled, arbitrarily adjust the room temperature. 6, home central air conditioning There are three types: water systems, wind systems and refrigerant system, the user can according to their residential characteristics, matching the different types of home central air conditioning.
