    • PURPOSE:To improve an efficiency of heat exchanging operation, increase a volume of ventilated air and apply multi-functions to the air ventilation device by a method wherein a heat pump circuit capable of reversing a circulating direction of coolant is used. CONSTITUTION:In case of performing an air conditioning and air ventilation for heating a room, a heat exchanger 19 is applied as an evaporator and a heat exchanger 20 is applied as a condenser so as to perform an air ventilation. In this case, a sensible heat in the indoor air flow 24 is transmitted from the heat exchanger 19 to the coolant, carried to the heat exchanger 20 and then transmitted to the outdoor air feeding flow 25. In case of performing an air conditioning and air ventilation during a cooling of the room, the heat exchanger 19 is applied as a condensor and the heat exchanger 20 is applied as an evaporator. If a compressor 28 is terminated for its operation and only the fans 21 and 22 are operated to perform the air ventilation, it is possible to realize a normal simultaneous air feeding, discharging and ventilation and this operation is useful for the ventilation or a cooling of outdoor air. As described above, since the heat is carried by the heat pump into the air flow of low temperature from the air flow of hot temperature contacting with the heat exchanger of heat absorbing side in a heat pump circuit, a high efficient heat exchanging operation can be performed. Further, a gas-liquid heat exchanger is applied, so that the device is made small in size and a high volume of air ventilation can be attained.
    • 目的:为了提高热交换操作的效率,通过使用能够反转冷却剂的循环方向的热泵回路的方法,增加通风空气的体积并对空气通风装置施加多功能。 构成:在进行空调和通风用于加热房间的情况下,作为蒸发器应用热交换器19,作为冷凝器使用热交换器20,进行通风。 在这种情况下,室内空气流24中的显热从热交换器19传递到冷却剂,被运送到热交换器20,然后传送到室外空气供给流25.在执行空调和空气的情况下 在室内冷却期间通风,热交换器19作为冷凝器施加,热交换器20作为蒸发器使用。 如果压缩机28被终止以用于其操作,并且只有风扇21和22被操作以执行空气通风,则可以实现正常的同时进气,排放和通风,并且该操作可用于通风或冷却 户外空气 如上所述,由于热泵从热泵回路中与吸热侧的热交换器接触的热温的空气流将热量输送到低温空气流中,所以可以有效地进行热交换 执行。 此外,应用气液热交换器,使得该装置的尺寸小,并且可以获得大量的空气通风。
