Q1：Why is it important to use home air conditioner filters?
A：Without them you can clog up vital parts of the heating or cooling components that can be difficult to clean out and can cause severe damage that will be much more expensive to repair than the inconvenience of replacing a filter once a month.
Q2：What is VRF Air Conditioning System?
A：VRF air-conditioning systems owe their growing popularity to their ability to meet a wide range of requirements.

Q:Ordinary household air conditioner can heating?
Air conditioning is KFR, now just heating refrigeration and power consumption.
Q:The demolition of household air conditioner?
Air conditioning units operating process: Switching (including replacement of indoor machine or need to recycle refrigerant), violate compasses operation may cause refrigerant recycling compressor, air conditioner switching is also a kind of frequent business, all need to be in the process of switching refrigerant recycling, but if the improper operation, will also be the worst effects of the compressor explosion. Operation: compressor running low voltage side to close the high-pressure valve, air conditioning system to run for a few minutes, the compressor suction air leakage explosion. Funnelled process analysis: due to air conditioner refrigeration system, the system internal cause low voltage side is funnelled has no refrigerant or a small amount of residual refrigerant, cause the compressor suction air and close running on the high side, the final explosion. Compressor explosion: the mechanism of air conditioner refrigeration cycle system high side blocked - compressor running to inhale air for several minutes, the compressor overheating - frozen oil overheating vaporization - compressor inside a huge increase in oil and gas mixture, temperature, pressure increased to achieve a certain pressure, temperature, mixture combustion of oil and gas compressor, a sharp rise in the temperature, pressure and compressive strength than the compressor shell and the compressor shell burst. Response: in front of the air conditioning switching operations, you must first open air conditioning to check operation parameters. Confirm the various performance parameters of the normal pressure gauge on the three-way valve process pipe connections, can close the high-pressure valve for refrigerant recovery, downtime when pressure is 0.1 MPa.
Q:Home air conditioning, the indoor machine should be evaporator, seg should be compressor,
Yes, refrigeration, the compressor discharge of high pressure high temperature gas on the first machine, cooling evaporation cooling after liquefaction to the machine, at that time, the machine is the condenser, the machine is an evaporator, on the contrary, heating, high temperature and high pressure gas home inside the machine, on the first discharge process of hot air, in fact is the process of condenser and cooling, and then to evaporation machine, at this time, the machine is the evaporator, the machine is a condenser. This is the transformation.
Q:The snow kind of what kind of air conditioning, they each have what effect
The snow kind of classified as: 1, domestic now is the most commonly used freon R22. 2, new environmental protection refrigerant R410a refrigerant, everything, R407c, etc. The role of the snow kind of: Snow also called freon, freon will gas compressor for high temperature and high pressure liquid freon compression, and then sent to the condenser (seg) become normal temperature high pressure liquid freon after cooling, so the blow out outdoor hot air. And then to the capillary, into the evaporator (indoor machine), because the freon from capillary to evaporator space suddenly increases, pressure decreases, and liquid freon will China gas, into a gaseous cryogenic freon, to absorb a lot of heat, the evaporator will become cold, indoor machine of the fan will indoor air blows from the evaporator, so indoor machine out of the cold wind is blowing; Water vapor in the air is cooled after the evaporator will turn into water droplets, along the conduit flow, this is the reason why air conditioning will be out of the water. Then gaseous freon to go back to the compressor compression, continue to cycle.
Q:Household air conditioning air supply isn't send outdoor wind indoor?
It isn't. Household air conditioning "air supply" mode is only play the role of fan. For household air conditioner, the vast majority of air distribution mode is only air conditioning fan motor working of the indoor machine, return air into the indoor air from air conditioning, blown out by the outlet fan motor, fan motor, air conditioner outdoor compressor doesn't work, such as play a role similar to ordinary fan, but the effect is far worse than a fan
Q:Household air conditioning separate-bodied air-conditioners can use hanging way
Hang it is hard to think of, the machine is shaking, the earthquakes are, expansion of loose, mainly in doubt about the quality of the now If possible, the best is the concrete casting is there is a corresponding structure hanging out
Q:The residential air conditioning machine within the power supply and power supply?
Outside the machine power supply unit, air conditioning unit of the main control board in the outdoor, indoor machine only within a relatively simple machine circuit board; Host machine power supply unit is mostly use 380 v3n ~ power; Such as split units, air cooling pipe machine, the fission of medium-sized above water source heat pump units, etc. Inside the machine power supply of the air conditioning, the main control panel is installed in the indoor machine, inside the main control board through on-off signal power supply for outdoor; Such as household wall air conditioning, household cabinet air conditioning; The machine power supply has the advantage of convenient, easy maintenance.
Q:Household air-conditioning vibration is big, very loud sound, how be to return a responsibility?
This is the window air conditioner, the general can refrigeration cases, the compressor is not a problem. Check whether the noise of the fan motor, the motor bearing aging, gap will cause vibration noise; Motor bracket is rust fracture, to find a way to repair the motor bracket. And isn't your fan leaves and no loss in or with dust caused the blades don't balance, cause vibrations running. These checks are open chassis, detach the front panel after see inside the body, remove fixed after the body of the screw, pulled out the body from the chassis to the front you can see what's inside.
Q:The fluorine plus air conditioning is what type?
Fixed frequency wall hang, R22, frequency conversion air conditioning, add R410. Freon classified as: 1, domestic now is the most commonly used freon R22. 2, new environmental protection refrigerant R410a refrigerant, everything, R407c, etc.
Q:Household air conditioning for 8 years to add snow kind?
Air conditioning snow kinds, namely R12, in terms of its physical and chemical properties and use there is no life, as long as the system is clean, not leak, do not contain water, compressor performance is good, is always available.
