Condensation temperature, be only the sensible heat portion of energy that indoor exhaust wind is utilized at this time；And in refrigeration, indoor second heat exchanger
(as main condenser) and the supplementary heat exchanger of outdoor are applied in combination, and ensure that the leaving air temp of unit；And when heating, unit can
It is switched between outer circulation pattern with recycling inside, interior cycle can quickly and effectively improve indoor temperature；And outside
Under circulation pattern, the air draft of indoor higher temperature improves the evaporating temperature of unit as heat source, used as evaporator
The heat that two heat exchangers absorb indoor exhaust wind is evaporated, and since the dew-point temperature of indoor exhaust wind is higher, and evaporating temperature is opposite
The dew-point temperature of air draft is relatively low, therefore has condensed water precipitation in evaporator surface, and what is recycled at this time is not only the aobvious of indoor exhaust wind
Hot part energy, while also having recycled the latent heat portion of energy of indoor exhaust wind.To, the energy of indoor exhaust wind can be made full use of,
It is energy saving.
