why the air condition condenser coil take ice in winter when it work in heat mode?

Question

in winter season air condition take ice the gas and power is ok but the condenser is take ice and blocked and heating is few special when the out sit temperature is minus zero degree
please gave me complete information

Answer 1

Since you mentioned that it is operating in the "heat mode" you most likely have a heat pump-style air conditioner.

In the cooling mode the outside condenser coil rejects heat from the house. In the heating mode the system reverses the flow of refrigerant so that heat is drawn into the outside coil which has now become the evaporator. Heat pumps work quite well at temperatures around freezing and even have cataloged performance data for well below freezing temperatures. The nature of the performance is that the colder it is outside the less heat you can draw in from it and the performance diminishes. In very cold weather, supplemental heating will be needed.

Whenever the outside coil is operating at sub-freezing temperatures there will be frost formation which will interfere with the performance if it progresses to a heavy thickness or to ice. Some frosting can even occur when the weather is above freezing and especially if it is humid. For this reason most heat pump units go through an automatic defrost cycle. This is most commonly set- up with a timer. When this is occurring you must rely on the built-in supplemental electric heating coils inside the unit to maintain heat delivery.

In low temperatures, Heat Pumps do not work well. This is because there isn't enough "heat energy" in the air for the Heat pump to take. Thats what a Heat Pump does, it takes heat from the outside air and puts it into the home or building. When the heat is taken from the outside air at the condenser coil, the air around the coil cools down causing moisture in the air to condense on the coil. If the temperature is below zero Celsius, then this moisture will freeze on the coil.

I think there are units with defrosters built in. Either way Heat Pumps, by their nature, do not work at low ambient temperatures.

Do you speak english? No one understand you when you talk like person not from place where english is talked. Your air condition takes ice? Why do you have air condition on in winter season? My heating is special but i do not sit on the temperature when the temperature is minus zero (WTF?) degree.
