The cause of the failure of the common evaporator frosting or temperature sensor circuit, the installation position of poor ventilation and dirty filter indoor machine.
引起该故障的原因常见为蒸发器结霜或温度传感器断路，室内机安装位置通风不畅以及过滤网太脏等。

High pressure fluid through the filter, the gush after the throttle body into the evaporator, and in the corresponding under low pressure, the quantity of heat of evaporation from around.
高压液体经过过滤器、节流机构后喷入蒸发器，并在相应的低压下蒸发，吸取周围的热量。
3
Liquid medium the dry filter to remove water, impurities, into the expansion valves throttling decompression, become a low voltage liquid medium, low temperature within in the evaporator gasification.
