As shown in connection with 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, an outdoor unit 10, a compressor, and a throttling element. The indoor unit, the compressor, the outdoor unit 10 and the throttling element form an air conditioning system through refrigerant pipelines.

The indoor unit includes a first heat exchanger 20 and a first fan, and the outdoor unit 10 includes a third heat exchanger and a second fan, and the first fan can drive indoor air flow to flow into the indoor unit from an air inlet of the indoor unit. The air flow flowing into the indoor unit exchanges heat with the first heat exchanger 20, and the first heat exchanger 20 exchanges heat with the air flow to adjust the temperature of the air flow. The air current after the temperature regulation flows out to the indoor through the air outlet of the indoor unit, and finally the effect of regulating the indoor temperature of the indoor unit is achieved.

The second fan can drive an airflow from an air inlet of the outdoor unit 10 into the outdoor unit 10. The inflow air can exchange heat with the third heat exchanger and then flow out through the outlet of the outdoor unit 10. The second fan can accelerate the heat dissipation or evaporation of the third heat exchanger.

When the air conditioner is refrigerating, the first heat exchanger 20 is an evaporator, and the third heat exchanger is a condenser. The refrigerant evaporates in the first heat exchanger 20, absorbs heat in the air, and turns into a gaseous refrigerant. The gaseous refrigerant flows to the compressor, and the compressor compresses the gaseous refrigerant into the high-temperature and high-pressure gaseous refrigerant. The high-temperature high-pressure gaseous refrigerant flows into the third heat exchanger, is liquefied and releases heat in the third 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, the medium-temperature high-pressure liquid refrigerant in the throttling device is decompressed into a low-temperature low-pressure gas-liquid mixture (more liquid), and then flows back to the first heat exchanger 20 for evaporation. Thus, the refrigeration cycle is completed, wherein the second fan drives the airflow to flow through the third heat exchanger, and the heat dissipation effect of the third heat exchanger can be improved.

The air conditioner also comprises a four-way valve, the four-way valve is communicated with the compressor, the first heat exchanger 20 and the third heat exchanger, and the flow direction of the refrigerant in the main refrigerant pipeline 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 20 is a condenser, and the third heat exchanger is an evaporator. The liquid refrigerant is evaporated in the third heat exchanger and changed into a low-temperature low-pressure gaseous refrigerant. The gaseous refrigerant flows into the compressor, and the compressor converts the low-temperature low-pressure gaseous refrigerant into the high-temperature high-pressure gaseous refrigerant. The high-temperature and high-pressure gaseous refrigerant flows into the first heat exchanger 20 through the four-way valve, is liquefied and releases heat in the first heat exchanger 20, 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 to be a low-temperature low-pressure gas-liquid mixture (more liquid). The low-temperature low-pressure gas-liquid mixture flows into the third heat exchanger again, and is evaporated and absorbed in the third heat exchanger to become a low-temperature low-pressure gaseous refrigerant. The low-temperature low-pressure gaseous refrigerant returns to the compressor through the four-way valve and then continues to circulate, and heating is finished. The second fan can accelerate evaporation of the refrigerant in the third heat exchanger.

Therefore, when the air conditioner performs cooling, the refrigerant flows in the direction of the outdoor unit 10, the throttling device and the indoor unit, and a low-temperature and low-pressure gas-liquid mixture is formed in a refrigerant pipeline from the outdoor unit 10 to the indoor unit. When the air conditioner heats, the refrigerant flows in the direction of the outdoor unit 10, the compressor and the indoor unit, and the outdoor unit 10 flows to a high-temperature and high-pressure gaseous refrigerant in a refrigerant pipeline in the indoor unit.

Optionally, the first heat exchanger 20 of the indoor unit communicates with the outdoor unit 10 through a first refrigerant pipeline 50, the mattress assembly 30 includes a mattress 301, a second heat exchanger 303, a fan 304 (hereinafter, referred to as a third fan 304 for convenience of distinction), and an air duct 305, the second heat exchanger 303 communicates with the outdoor unit 10 through a second refrigerant pipeline 60, and the first heat exchanger 20 and the second heat exchanger 303 are arranged in parallel. It can be understood that: when the air conditioner performs cooling, the outdoor unit 10 supplies a low-temperature and low-pressure gas-liquid mixed refrigerant to both the first heat exchanger 20 and the second heat exchanger 303. When the air conditioner heats, the outdoor unit 10 supplies high-temperature and high-pressure gaseous refrigerant to both the first heat exchanger 20 and the second heat exchanger 303.

The mattress 301 defines a cavity 302, an air duct 305 is positioned in the cavity 302, the second heat exchanger 303 is positioned at an inlet 3051 of the air duct, the third fan 304 can drive air flow to flow into the air duct 305 after passing through the second heat exchanger 303, and the air duct 305 is used for adjusting the temperature of the mattress 301. That is, when the air conditioner cools, the air duct 305 can supply cool air to the mattress 301 by the flow of the cooling air flowing in the air duct 305. When the air conditioner is heating, the air duct 305 can supply hot air to the mattress 301 by the hot air flow flowing in the air duct 305.

With this alternative embodiment, the second heat exchanger 303 is connected in parallel with the first heat exchanger 20, and the refrigerant flowing out of the outdoor unit 10 is divided into two paths, which flow to the first heat exchanger 20 and the second heat exchanger 303, respectively, that is, the bed air conditioner assembly is in a one-to-two manner. Therefore, the indoor unit can work normally and adjust the indoor temperature. The third fan 304 drives the airflow to exchange heat with the second heat exchanger 303, the heat exchange airflow after exchanging heat with the second heat exchanger 303 flows into the air duct 305 again, and the air duct 305 is located in the mattress 301. The air duct 305 exchanges heat with the mattress 301 to regulate the temperature of the mattress 301. In this way, the refrigerant of the air conditioner can be selected according to the requirement without considering the influence of the temperature of the second heat exchanger 303 on the temperature of the mattress 301. That is to say, the bed type air conditioning assembly of this embodiment can not only not influence the normal operating of air conditioner, can also guarantee the temperature of mattress 301, increases user's use experience.

In the correlation technique, set up second heat exchanger 303 (heat exchange coil) inside mattress 301, mattress 301 is because the travelling comfort needs flexible material, so stress point on mattress 301 is inhomogeneous, pressure is also inhomogeneous, and inside device (for example heat exchange coil) is fragile, even take safety measure protection refrigerating plant, also can not ensure 100% safety, if indoor side takes place to reveal, other chemical refrigerant have certain toxicity.

With this alternative embodiment, the user can control the outdoor unit 10 to be connected or disconnected with the first heat exchanger 20 and/or the second heat exchanger 303 according to the requirement, so as to control the operation of the mattress assembly 30 and/or the indoor unit. For example, when the user is in bed for a long time and the activity range is small, the second heat exchanger 303 can be controlled to be communicated with the outdoor unit 10, and the first heat exchanger 20 is disconnected from the outdoor unit 10, so that the mattress assembly 30 can work alone. The indoor unit does not need to work, and energy consumption of the air conditioner can be saved. When the user leaves the mattress 301, the first heat exchanger 20 can be controlled to be connected with the outdoor unit 10, and the second heat exchanger 303 is controlled to be disconnected with the outdoor unit 10, so that the energy consumption of the mattress assembly 30 can be reduced. The first heat exchanger 20 and the second heat exchanger 303 may be both communicated with the outdoor unit 10 to increase indoor heat exchange air volume and increase indoor temperature adjustment effect.

Optionally, the opening degree of the control valve 40 is adjustable, so that the flow rate of the refrigerant in the second heat exchanger 303 can be adjusted, and thus the temperature of the mattress 301 can be adjusted.
