Air-conditioning mainframe partially inspected maintenance
Temperature switches: normal use of the check switch valve
13. Water flow switches: normal use of the inspection switch valve
Emission valves, recharge valves: normal use of the inspection switch valves
15, ribs: combing, cleaning
16, belts: check whether the belts are fractured or badly worn, check whether the belts are too loose, and check whether the wheels and axes are loose
17, water dispensers: check whether the water dispenser is evenly distributed
Refilling float valves: check the reliability of recharge float valves
Capacitivity: checks for the transformation of the capacitor, expansion of the drum or cracking
20, signals, indicators: check if the signals are normal and check if the indicators are correct

Reason why the air conditioner doesn't heat
Reasons for non-heating air conditioning: low outdoor temperatures。
The low outdoor temperature makes air conditioners not working normally below zero, while the outdoors of the fac are no longer heating normally at around 15 below zero, so it is possible that the outdoors are too low, the air conditioners are not frosting and the air conditioners are not heating。
What if the air conditioner does not heat because of this: using tools to clear the air conditioner from frost can fix it。
Reason for non-heating air conditioning: four valve leaks of air conditioning。
Four valves: hydraulic valves are the control valves with four oil mouths. The four valves, which are essential components of the refrigeration equipment, operate on the basis that, when the electromagnetic valves are in a state of power outage, the first slide valves move down the right compression spring to the left, the high-pressure gas enters the cavity tube 1 into the right piston cavity cavity, and, on the other hand, the gas from the left piston vent is discharged, because of the pressure differential at both ends of the piston, the piston and the main slider move left, which connects the vents with the outside machine, and the other two takeovers are connected to each other to form the cooling 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。

The benefits of regular cleaning of glac
Benefits of regular cleaning of glac:
Beijing glac maintenance reminder to clean up every one to two months as appropriate or twice a year less. Effective removal of all types of contamination from air-conditioning evaporation units, removal of pollutants from air-conditioning, smell of air, self-dispersed solid dust from air-conditioning units, regular cleaning to keep indoor air clean and to allow the body to live in a clean environment。
Extension of the useful life of air conditioners。
3. More efficient power: if every dirty air conditioner is cleaned in a timely manner, it will save about 10-30 per cent of household electricity, and users will save about $700 per year for only a small amount of cleaning. Save your money。
