MXY2G20VA2 normal rating is 4.5kw (15,355 btu). COP (coefficient of performance) describe the heating and cooling efficiency of air conditioners ie the amount of BTU produced by the air-con using 1 watt of electricity per hour. The higher the COP the more energy efficient is the equipment. If you want energy efficiency, you should choose a 5-Tick energy efficient air-con.
Armaflex and Aerofoam are both brand names of aircon Insulation tubes.. don't get con.
Thicker is better, but also means larger trunkings which is ugly. My aircon system is using 1/2" thick amaflex insulation.
daikin because of its r32.
Aircon pipe cannot anyhow increase or decrease pipe diameter. For refrigerant natural properties, the higher the pressure, the higher the temperature of the gas. By going smaller from 1/2" to 3/8" at FCU, u r increasing the pressure of the gas which will increase its temp. FCU is supposed to receive cool liquid refrigerant so that it can absorb heat from the room to change into warm gas to the compressor as part of cycle. At the same time, the inner fan will push the coolness out of tube and into the room. If FCU inlet gas is alrdy warm, then it will not cool the room effectively.
Choose the one which your budget is comfortable with. No one would be able to know whether the cool air from your aircon is coming from R410a or R32 aircon refrigerant.
Depends on the workmanship skills. When the installer did the insulation for my system, he could fit the insulation when the copper pipe bends 90d without any gaps.
I think you do not know what is the thickness of the insulation for, it is to prevent condensation (aka sweating). It has nothing to do with the thickness of the copper pipes.
Ouh i tot he want reduce pipe to 3/8" for his fcu. lol. ACtually i thought most if nt all gives 1/2" insulation. gt ppl offer 3/8"?
I ever once been to my friend's home, his aircon trunking was dripping water from the condensation. I guess the insulation thickness was thin, should be a 3/8". So don't skim on the quality, it may end up costing more than just money, it also create trouble and time trying to fix it.
prolonged condensation on the fins which then results in mold and bacteria growth, hence the smell. to reduce this, turn on the mold proof setting if your aircon has it (AFAIK some Daikin models have this), and do not air the room immediately after turning off the aircon (this prevents higher humidity outside air from entering and condensing on on the cold fins of the aircon that was just turned off).
Nope never done before. For some reason only 1 of my unit got this smell, the other 3 units don't have this weird smell.
I don't see such a setting on my mitsubishi electric, what a good way to simulate something like this? I can control via my smart home remote, is it some sort of dry mode?
