    • An air conditioner comprises an air-to-air heat exchanger; a fresh air supply duct, a fresh air by-pass duct, a used air exhaust duct, and a used air by-pass duct, the fresh air supply duct and the used air exhaust duct being respectively connected to the air-to-air heat exchanger, the fresh air supply duct having a part in common with the used air by-pass duct, and the used air exhaust duct having a part in common with the fresh air by-pass duct. Included are a condenser provided in the common part of the fresh air supply duct, and an evaporator provided in the common part of the used air exhaust duct, the condenser and the evaporator being parts of a heat pump. A blower is provided in the common part of the fresh air supply duct and is connected to the used air by-pass duct, and a separate blower is provided in the common part of the used air exhaust duct and is connected to the fresh air by-pass duct. A first three-way valve is arranged in the used air exhaust duct in front of the air-to-air heat exchanger, and a second three-way valve is arranged in the fresh air supply duct behind the air-to-air heat exchanger viewed in the direction of fresh air supply for switching the air conditioner into first, second and third modes wherein the air conditioner functions as a heat pump, a heat pump and a fresh air supplier, and a fresh air supplier, respectively.
    • 空调器包括空气 - 空气热交换器; 新鲜空气供应管道,新鲜空气旁通管道,废气排放管道和二次空气旁通管道,新鲜空气供应管道和废气排放管道分别连接到空气到空气 热交换器,新鲜空气供应管道具有与所使用的空气旁通管道共同的部分,并且废气排放管道具有与新鲜空气旁通管道共同的部分。 包括设置在新鲜空气供应管道的公共部分中的冷凝器和设置在废气排放管道的公共部分中的蒸发器,冷凝器和蒸发器是热泵的部件。 在新鲜空气供给管道的公共部分设置有鼓风机,并连接到二次空气旁通管道,并且在废气排放管道的公共部分设置单独的鼓风机,并且通过以下方式连接到新鲜空气 通道。 在空气 - 空气热交换器前面的废气排放管道中设置有第一三通阀,在空气 - 空气热交换器后面的新鲜空气供给管道中设置有第二三通阀 从新鲜空气供给的方向观察,将空调切换为分别作为热泵,热泵和新鲜空气供应器的空调机和新鲜空气供应器的第一,第二和第三模式。
