1: air conditioner catheters or one-way valves have problems
Hair catheters: a catheter network simulates a leaf vein and a human catheterary mechanism consisting of a catheter tube with an outer diameter of 3. 5-5. 0 mm (around 0. 9 mm wall thickness) and a backwater main pipe with an outer diameter of 20 mm (2 mm wall thickness or 2. 3 mm)。
One-way valves: also known as revolving valves or reversible valves. It is used in hydraulic systems to prevent reverse flow of oil or in gaseous systems to prevent reverse flow of compressed air。
What if the air conditioner doesn't heat because of this

2: air conditioner four valves malfunctioning
Four valves: the four valves are essential components of the refrigeration equipment. The working method is that, when the electromagnetic valves are in a state of power outage, the first slide valve moves down to the left with the right compression spring, the high-pressure gas enters the cavity tube 1 and enters the right-end piston cavity cavity, and, on the other hand, the gas is discharged from the left piston cavity, due to the pressure differentials at both ends of the piston, the piston and the main slider move left, which connects the vents with the outdoor machine, and the other two take-overs are connected to form the refrigeration cycle。
What about the non-heating of the air conditioners caused by this cause: the replacement of the four valves will solve the non-heating of the air conditioners。
3: declining efficiency due to ageing ac compressors or breakdown of compressors
What about the non-heating of the air conditioner caused by this cause: replacement of compressor will solve the non-heating of the air conditioner。

4: rooms are too high
The interior air conditioner was inappropriately installed, in which case the hot air floated and gathered above the room。
What if the air conditioner is unheated as a result of this: re-select the location of the inner air conditioner. It may also be possible to add a windshield, or to extend the vent, and the central air conditioner can replace the wide-leaf vent, adjust the wind delivery angle and rewind the heat to a lower position。

5: fluorine deficiency in air conditioners
Shortages of fluorine in air conditioners not only do not cool, but can also cause heat effects. Most air conditioners are now heat pump type or heat pump-enabled electro-heated air conditioner, both of which work using freon when evaporated to heat from outdoor air, and cannot function normally without fluorine, which can prevent heating。
What if the air conditioner that results from this cause is not hot。

6: air conditioner out of or back to wind
When the wind vent is blocked, the air current is short, the wind is straight back to the wind vent, the air conditioning is not working, and the air-conditioning auxiliary heat cannot be activated
What if the air conditioner caused by this cause is not thermal: remove the object from the wind vent or return to it。
Here's a picture of the dust-proof film that was installed without being removed

7: the filtration net contains dust that prevents the in-house calorie from being brought out in time by mobile air, resulting in a shortage of heat
Air-conditioning air filters are too dusty and internal and external vents are blocked by foreign objects. The role of filters is to absorb the dust from the air, and if too much dust is accumulated and not cleaned in time, the flow of the air is blocked, resulting in reduced wind flow from the vent, which prevents in-house calorie from being brought out in time and leads to insufficient heat。
What if the air conditioner doesn't heat because of this: clean up the filter, and it doesn't heat。


8: air conditioning heat is too low
The size of the room varies, as does the number of air conditioners to be applied, and the corresponding number of air conditioners should be larger if the air is not so closed and the sun is so closed. If the room is relatively large and the number of air conditioners selected is relatively small, the problem can easily arise。
The solution is to increase the heat source and to negotiate with users to replace larger air conditioners
9: low outdoor temperatures or electricity bad
The low outdoor temperature prevents the air conditioner from working normally, while the outdoor temperature is too low for the outside air conditioner to frost and heat. In addition, the low voltage may have a direct impact on the heating effect of air conditioning。
10: frost controller failure
The inability of air conditioners to move into the frosting state in a timely manner can result in the freezing of evaporation units during heat pumps, which affects the heat exchange efficiency of air-conditioning, resulting in insufficient heat production and even a stoppage. Emphasis should be placed on observing whether the frosting thermostats are misplaced, sticky or poorly exposed, wind turbines slide or windways blockage, electromagnetic valves or starters fail。
For heat pump-aided electro-heated air conditioners, where the temperature of the heat is normal at a higher ambient temperature (above 5°c) and the temperature at a lower ambient temperature (below 0°c) is insufficient or non-heat, the failure of the electro-heating control circuit or electro-heating equipment should be suspected and the maintenance should focus on the examination of both components。
