热泵制热是利用制冷系统的压缩机冷凝热来加热室内空气的

空调器工作时，制冷系统内的低压、低温制冷剂蒸气被压缩机吸入并压缩为高压、高温的过热蒸气后排至冷凝器；同时室外侧风扇吸入的室外空气流经冷凝器，带走制冷剂放出的热量，使高压、高温的制冷剂蒸气结为高压液体。高压液体经过节流毛细管降压降温流入蒸发器，并在相应的压力下蒸发，吸取周围热量，同时室内侧风扇使室内空气不断进入蒸发器的翅片间进行热交换，并将放热后变冷的气体送向室内。如此室内外空气不断循环流动，达到降低温度的目的。
When the air conditioner is working, the low-pressure and low-temperature refrigerant vapor in the refrigeration system is sucked in by the compressor and compressed into high-pressure and high-temperature superheated vapor, which is then discharged to the condenser; At the same time, the outdoor air sucked in by the outdoor side fan flows through the condenser, taking away the heat released by the refrigerant, causing the high-pressure and high-temperature refrigerant vapor to form a high-pressure liquid. High pressure liquid flows into the evaporator through a throttling capillary to reduce pressure and cool down, and evaporates at the corresponding pressure, absorbing surrounding heat. At the same time, the indoor side fan continuously enters the fins of the evaporator for heat exchange, and sends the cooled gas that has been released to the indoor environment. In this way, the indoor and outdoor air continuously circulates and flows, achieving the goal of reducing temperature.
热泵制热是利用制冷系统的压缩机冷凝热来加热室内空气的，空调器在制冷工作时，低压、低温制冷剂液体在蒸发器内蒸发吸热，而高温、高压制冷剂气体在冷凝器内放热冷凝。热泵制热是通过电磁四通换向阀来改变制冷剂的循环方向的，原来制冷工作时作为蒸发器的室内盘管，变成制热时的冷凝器，实现制热的。
Heat pump heating uses the condensation heat of the compressor in the refrigeration system to heat indoor air. During the refrigeration operation of the air conditioner, low-pressure and low-temperature refrigerant liquids evaporate and absorb heat in the evaporator, while high-temperature and high-pressure refrigerant gases release heat and condense in the condenser. Heat pump heating is achieved by changing the direction of refrigerant circulation through an electromagnetic four-way directional valve. Originally used as an indoor coil in the evaporator during refrigeration, it has been transformed into a condenser during heating, achieving heating.
由于热泵空调器是通过吸收室外热量来制热的，所以热泵制热能力随室外温度的变化而变化，一般室外气温为0℃时，其制热量为名义制热量的80%。室外气温为-5℃时，其制热量为名义制热量的70%
Due to the fact that heat pump air conditioners generate heat by absorbing outdoor heat, the heating capacity of heat pumps varies with changes in outdoor temperature. Generally, when the outdoor temperature is 0 ℃, its heating capacity is 80% of the nominal heating capacity. When the outdoor temperature is -5 ℃, its heating capacity is 70% of the nominal heating capacity
