Don't air conditioning heating is what reason

can normal refrigeration and air conditioning in the summer, in the winter heating effect is very poor, conditioning or not, if you have this kind of trouble, please follow mall together to find out the cause of the air conditioning is not heating ulla: step: confirm air conditioning heating function. Some can not all air conditioning heating, air conditioning is specially designed for the south, these places don't need to keep warm in the winter temperature is higher, so there was no air conditioning heating function, if you buy this kind of air-conditioning system, there is no heating. Please check the air conditioning instruction or consulting air conditioning manufacturers. Step 2: check whether the power socket electricity ( If can open air conditioning, please skip step 2 directly into 3) 。 Electricity pen or electric fan, small electric equipment under test power supply, if normal, check the air conditioning is plugged in again good, air conditioning energizing or there will be a 'drop' sound after the prompt screen prompts. Then starts with a remote control air conditioning, if cannot be started, need to check whether the remote control is normal: open the mobile phone in the photo, the remote control to be detected on the camera, press the remote control button, observe whether there is a white spot on the phone's screen: 1. If only a few buttons doesn't work, that means the battery is normal, open the remote wipe with alcohol can generally be back to normal, or replacement of the remote control. 2. If not, that means batteries, replace the battery; 3. If normal but after pressing the air conditioning remote control without any response, may be a computer fault, need to repair. Three steps: check whether the compressor is started. Air conditioning is turned on, can hear the sound a lot of people think that air conditioning in operation, a lot of the time may be only the voice of the fan rotation and compressor isn't started, if air conditioning showed the following conditions, it is probably the reason: 1. Air conditioning has no heating effect; 2. Outside the machine copper pipe drying ( Under normal circumstances there will be dew) ； 3. Touch the machine, there is no sense of jitter ( Under normal circumstances have obvious jitter) 。 Meet the above three points, basic can determine the air conditioning compressor shut down. Compressor stalling, general line fault or mechanical failure is air conditioning, need to find a professional maintenance personnel for repair. Step 4: check whether the air conditioning is need to add fluoride. Air conditioning refrigeration needs not only freon, heating also need, if the lack of fluorine of air conditioning, can lead to no heating. With fluoridated tool detection under pressure, if the pressure is too low, it means no refrigerant, need to add fluoride. Step 5: check whether the heat exchanger is need to be cleaned. For indoor and outdoor air conditioning need heat exchanger heat transfer, when heat exchanger covered a lot of the rubbish such as dust and spider web, cannot effectively heat exchange, lead to air conditioning heating effect is poor, need internal and external machine heat exchanger and filter cleaning. Step 6: check whether the voltage is stable. Peak power supply voltage is unstable, can not meet the normal voltage needed for the air conditioning, can lead to poor air conditioning refrigeration or not effect, high temperature during a lot of air conditioning runs at the same time are more likely to appear this kind of phenomenon. This problem cannot be solved by individual is can choose frequency conversion air conditioning. Step 7: check machine outside the environment temperature is too low. Commonly used air condition in our more temperate climates T1 condition, environment temperature in - shall apply 7 ℃ to - 43 ℃ between, when the environment out of the range, cannot effectively heat transfer machine heat exchanger outside, will result in heating or air conditioning heating effect is poor. Need to change the machine use environment, foreign machine to heat up.
