The arrows in FIG. 4 indicate the direction of flow of the heat exchange medium.

As shown in fig. 1-4, embodiments of the present disclosure provide a bed air conditioning assembly that includes an air conditioner and a mattress assembly 30.

The air conditioner includes an indoor unit 20, an outdoor unit, a compressor 60, and a throttling element. The indoor unit 20, the compressor 60, the outdoor unit, and the throttle unit form an air conditioning system through a refrigerant pipe 202.

The indoor unit 20 includes a first heat exchanger 201 and a first fan, and the outdoor unit includes a second heat exchanger and a second fan, and the first fan can drive indoor air to flow into the indoor unit 20 from an air inlet of the indoor unit 20. The air flow flowing into the indoor unit 20 exchanges heat with the first heat exchanger 201, and the first heat exchanger 201 exchanges heat with the air flow to adjust the temperature of the air flow. The air flow after temperature adjustment flows out to the indoor through the air outlet of the indoor unit 20, and finally the effect of adjusting the indoor temperature of the indoor unit 20 is achieved.

The second fan can drive the air flow to flow into the outdoor unit from the air inlet of the outdoor unit. The inflowing air flow can exchange heat with the second heat exchanger and then flows out through the air outlet of the outdoor unit. The second fan can accelerate the heat dissipation or evaporation of the second heat exchanger.

When the air conditioner is refrigerating, the first heat exchanger 201 is an evaporator, and the second heat exchanger is a condenser. The refrigerant evaporates in the first heat exchanger 201, absorbs heat in the air, and turns into a gaseous refrigerant. The gaseous refrigerant flows to the compressor 60, and the compressor 60 compresses the gaseous refrigerant into a high-temperature and high-pressure gaseous refrigerant. The high-temperature high-pressure gaseous refrigerant flows into the second heat exchanger, is liquefied and releases heat in the second heat exchanger, and is changed into a medium-temperature high-pressure liquid refrigerant. The medium-temperature high-pressure liquid refrigerant flows through the throttling device for throttling, and the medium-temperature high-pressure liquid refrigerant is depressurized into a low-temperature low-pressure gas-liquid mixture (more liquid) in the throttling device, and then flows back to the first heat exchanger 201 for evaporation. Thus, the refrigeration cycle is completed, wherein the second fan drives the airflow to flow through the second heat exchanger, and the heat dissipation effect of the second heat exchanger can be improved.

The air conditioner further comprises a four-way valve, the four-way valve is communicated with the compressor 60, the first heat exchanger 201 and the second heat exchanger, and the flow direction of the refrigerant in the main refrigerant pipeline 202 can be changed by the four-way valve. Thus, the air conditioner has the functions of cooling and heating at the same time.

When the air conditioner heats, the first heat exchanger 201 is a condenser, and the second heat exchanger is an evaporator. The liquid refrigerant is evaporated in the second heat exchanger and changed into a low-temperature low-pressure gaseous refrigerant. The gaseous refrigerant flows into the compressor 60, and the compressor 60 converts the low-temperature and low-pressure gaseous refrigerant into a high-temperature and high-pressure gaseous refrigerant. The high-temperature and high-pressure gaseous refrigerant flows into the first heat exchanger 201 through the four-way valve, is liquefied and releases heat in the first heat exchanger 201, and is converted into a medium-temperature and high-pressure liquid refrigerant. The medium-temperature high-pressure liquid refrigerant flows through the throttling device, and the medium-temperature high-pressure liquid refrigerant is reduced into a low-temperature low-pressure gas-liquid mixture (more liquid). The low-temperature low-pressure gas-liquid mixture flows into the second heat exchanger again, and is evaporated and absorbed in the second heat exchanger to become a low-temperature low-pressure gaseous refrigerant. The low-temperature and low-pressure gaseous refrigerant returns to the compressor 60 through the four-way valve, and then continues to circulate, thereby completing heating. The second fan can accelerate evaporation of the refrigerant in the second heat exchanger.

Therefore, when the air conditioner performs cooling, the refrigerant flows in the direction of the outdoor unit, the expansion device, and the indoor unit 20, and the refrigerant pipe 202 from the outdoor unit to the indoor unit 20 is a low-temperature, low-pressure gas-liquid mixture. When the air conditioner is heating, the refrigerant flows in the direction of the outdoor unit, the compressor 60, and the indoor unit 20, and the outdoor unit flows into the high-temperature and high-pressure gaseous refrigerant in the refrigerant pipe 202 in the indoor unit 20.

Therefore, the heat exchange area between the first heat exchange pipeline 302 and the mattress 301 can be increased as much as possible, and the heat exchange effect between the first heat exchange pipeline 302 and the mattress 301 is increased. For example, if the mattress 301 has a rectangular shape, the first heat exchange circuit 302 has a rectangular shape.

Optionally, the mattress assembly 30 further includes a thermostat in communication with the first heat exchange line 302. Specifically, the thermostat is a hollow structure, and a heat storage medium is filled in the hollow structure.

The heat storage medium is subjected to biological change at a specific temperature (such as a phase change temperature), absorbs or emits heat, and can be used for controlling the temperature of the surrounding environment to achieve a constant temperature effect. The heat or cold can be stored and released slowly when needed, so that the utilization rate of energy is improved, the environment is protected, and resources are saved. Under the bed type air conditioning component heating working condition, when needing to defrost, the heat storage medium can also keep warm, and the change of rapid reduction of the temperature of the upper layer of the mattress 301 caused by refrigeration under the defrosting working condition can not be caused.

Optionally, the mattress 301 is further provided with a water outlet on the sidewall or bottom wall, the water outlet is communicated with the first heat exchange pipe 302, and the water outlet can discharge the condensed water generated by the first heat exchange pipe 302.

Alternatively, the air conditioner may be a cabinet air conditioner, a wall-mounted air conditioner, a window air conditioner, or the like.

The above description and the drawings sufficiently illustrate embodiments of the disclosure to enable those skilled in the art to practice them. Other embodiments may include structural and other changes. The examples merely typify possible variations. Individual components and functions are optional unless explicitly required, and the sequence of operations may vary. Portions and features of some embodiments may be included in or substituted for those of others. The embodiments of the present disclosure are not limited to the structures that have been described above and illustrated in the drawings, and various modifications and changes can be made without departing from the scope thereof. The scope of the present disclosure is limited only by the appended claims.
