Technical Field

The utility model relates to the technical field of air conditioners, in particular to an air conditioning system and an air conditioning unit.

Background

At present, the main stream machine type of the existing air conditioner has a heat exchange function of a cooling and heating dual mode. Under the condition of higher indoor temperature, the indoor temperature is reduced by the air conditioner; in the case where the indoor temperature is low, the indoor temperature is raised by the air conditioner. The water source air conditioner is more and more favored by users due to the advantages of energy conservation, environmental protection, high heat exchange efficiency, low running noise, free and changeable combination of indoor and outdoor units and the like.

For example, related art discloses a water source air conditioner, which comprises an outdoor unit, a water fluorine exchange unit and a water tank. The outdoor unit is provided with a compressor and an outdoor heat exchanger; the water-fluorine exchange unit is provided with a fluorine-water heat exchanger and a water pump; the water tank is provided with a coil pipe; the coil pipe is connected with the water pump through a pipeline, the exhaust port of the compressor is sequentially connected with the outdoor heat exchanger, the fluorine water heat exchanger and the air inlet of the compressor through pipelines, and when the water source air conditioner is used for refrigerating and heat recovery, independent heating and hot water preparation by the heat pump, high-temperature and high-pressure air exhausted by the compressor completely enters the fluorine water heat exchanger for heat exchange, so that the energy loss is low.

In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:

when the water source air conditioning unit performs heating operation or refrigerating operation, the flowing directions of the refrigerant in the fluorine water heat exchanger are opposite, and the flowing direction of water introduced into the fluorine water heat exchanger by the water tank is fixed. Thus, the heat exchange efficiency of the fluorine water heat exchanger is related to the operation mode of the water source air conditioning unit. Therefore, under different operation modes, the water source air conditioning unit can influence the heat exchange efficiency of the fluorine water heat exchanger, and further influence the performance of the water source air conditioning unit. On the other hand, if the heat exchange efficiency of the fluorine water heat exchanger is increased, the heat exchange area of the fluorine water heat exchanger is generally increased, so that the manufacturing production cost is increased, the installation space of other parts of the air conditioner is reduced, and the air conditioner is difficult to produce and install.
