What's wrong with the warm air of Liugong 965 air conditioner?

1, there is something wrong with the capillary or check valve.

This is also the main reason why air conditioners do not heat. Whether it is air conditioning heating or cooling, it uses capillary network to quickly dissipate heat and cool. If the capillary network is damaged or has problems, even if the whole room can be heated and cooled, it will be very slow, because there are no two things to stop the air from flowing in the opposite direction. If these two things are damaged, there may even be a reverse cooling and heating effect. Just find a professional to repair and replace this problem.

The indoor temperature is too low.

This can only happen in the cold northeast, and the indoor temperature may reach about MINUS 30 degrees. If the floor heating is broken, the whole family can only rely on air conditioning to keep warm. At this time, the air conditioner has actually frosted. The main function of the air conditioner is to inhale cold air and bring it into the four-way valve to raise the temperature bit by bit. However, if the air conditioner has frosted inside, that is to say, the components inside the air conditioner can't work normally at all, and the frosted moisture after starting directly leads to the short circuit damage of the air conditioner, so this situation.

There is too much dust in the filter.

Scientific research has proved that the filter screen of air conditioner is the dirtiest place. Blowing the air conditioner for a long time may cause headaches and nausea. Generally, it is because the air conditioner has been used for too long that the filter screen is soaked with a lot of dirty things, which carry a lot of bacteria and viruses. If the air conditioner cools and heats, it will do great harm to the human respiratory system, and these foreign objects will block the filter mouth in the filter net, which will make the circulation of cold air and hot air not smooth, and the heat of hot air itself will dissipate faster.

4. The air conditioner lacks freon.

Everyone's impression is that Freon is a kind of refrigeration material, but the lack of Freon will directly affect the heating effect, so I have to mention the working principle of air conditioning. Air conditioning generally uses electric heating, so the working principle is generally to use Freon evaporation. Why sit in a pot of hot water, and your hands will be particularly hot after the lid is lifted, because water vapor condenses into water droplets when it meets solids, which is exothermic in this case. The working principle of freon in air conditioning is that solid turns into gas, and this process is also exothermic.
