Description

Technical Field

[0001] This utility model belongs to the field of air conditioning system technology, and specifically relates to an air conditioning system. Background Technology

[0002] Hollow core slab construction is a building structure built using cast-in-place reinforced concrete. It mainly consists of reinforcing steel bars, concrete, and an inner formwork. A honeycomb-like cavity structure is formed within the concrete by embedding an inner formwork (such as a honeycomb core, GBF high-strength thin-walled tube, thin-walled square box, or building shell structure). Figure 6 As shown, this reduces the use of vertical components, thereby reducing material consumption and construction costs.

[0003] To improve the temperature environment inside hollow-core slab buildings, air conditioning systems, such as heat pump air conditioners, are typically installed. A heat pump air conditioner is an air conditioning system that uses heat pump technology to achieve both cooling and heating functions. It mainly consists of an indoor heat exchanger, an outdoor heat exchanger, a compressor, a capillary tube, a gas-liquid separator, and a four-way valve. Its working principle is as follows: during operation, the four-way valve switches between cooling and heating modes. In cooling mode, the indoor heat exchanger acts as an evaporator, and the outdoor heat exchanger acts as a condenser, thus lowering the indoor temperature. In heating mode, the indoor heat exchanger becomes a condenser, and the outdoor heat exchanger becomes an evaporator, thus raising the indoor temperature. Heat pump air conditioners have advantages such as energy saving, environmental friendliness, and low cost. However, they can be noisy during operation, tend to create directional airflow, and, with prolonged use, can cause high indoor humidity, thus affecting the user experience.

[0004] Therefore, it is necessary to provide an air conditioning system to address the aforementioned technical problems.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide an air conditioning system that can solve the problems mentioned above in the background.

[0007] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0008] An air conditioning system includes a hollow floor slab, a heat pump air conditioner, and an exhaust fan. The hollow floor slab contains a gas flow channel. The heat pump air conditioner includes an evaporator or a condenser, which is connected to the gas flow channel. The exhaust fan is installed in a channel in the side wall of the hollow floor slab. The exhaust fan, the channel of the evaporator or condenser, and the gas flow channel form a closed airflow space. The exhaust fan is used to create negative pressure in the gas flow channel, carrying away the cold or hot airflow generated by the heat pump air conditioner.

[0009] In one or more embodiments of this utility model, the hollow floor slab includes a hollow slab and a plurality of inner molds, all of which are installed on the hollow slab, and a steel mesh is installed between the hollow slab and the inner molds.

[0010] In one or more embodiments of this utility model, the exhaust fan outlet is connected to a return pipe, and the return pipe is connected to the exhaust outlet of the evaporator or condenser.

[0011] In one or more embodiments of this utility model, a one-way valve is installed on the return pipe.

[0012] In one or more embodiments of this utility model, the inner mold is a thin-walled square box, and multiple thin-walled square boxes are connected in series through connecting pipes to form a gas flow channel.

[0013] In one or more embodiments of this utility model, a heat-conducting plate is provided between the thin-walled square box and the steel mesh.

[0014] In one or more embodiments of this utility model, the thin-walled square box is a heat-insulating or heat-conducting plate. When the thin-walled square box uses a heat-insulating plate, it can perform unidirectional radiative heat conduction. When the thin-walled square box uses a heat-conducting plate, it can perform bidirectional radiative heat conduction.

[0015] In one or more embodiments of this utility model, the inner mold is a hollow tube, and a connecting pipe is connected between adjacent pairs of hollow tubes. Multiple hollow tubes are connected in series through multiple connecting pipes to form a gas flow channel.

[0016] In one or more embodiments of this utility model, a metal buckle is engaged on the hollow tube, and the hollow tube is connected to the steel mesh through the metal buckle.

[0017] Compared with the prior art, the air conditioning system of this utility model can combine a hollow floor slab with a heat pump air conditioning system.

[0027] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0028] like Figures 1 to 5As shown, an air conditioning system according to one embodiment of this utility model includes a hollow floor slab, a heat pump air conditioner 2, and an exhaust fan 3. A gas flow channel is provided inside the hollow floor slab. The heat pump air conditioner 2 includes an evaporator or a condenser, which is connected to the gas flow channel. The exhaust fan 3 is installed in a channel in the side wall of the hollow floor slab. The exhaust fan 3, the channel of the evaporator or condenser, and the gas flow channel form a closed airflow space that is connected. The exhaust fan 3 is used to generate negative pressure in the gas flow channel, carrying away the cold or hot airflow generated by the heat pump air conditioner 2.

[0029] The heat pump air conditioner 2 and the exhaust fan 3 operate. Heat pump air conditioner 2 generates gas during operation, and exhaust fan 3 creates negative pressure in the gas flow channel. Since the evaporator or condenser of heat pump air conditioner 2 is connected to the gas flow channel, exhaust fan 3 can draw in the gas generated by heat pump air conditioner 2 and make it flow within the gas flow channel. The heat generated by the gas from heat pump air conditioner 2 radiates into the room through the hollow floor slab, achieving a cooling or heating effect.

[0030] like Figures 1 to 5 As shown, the hollow core slab includes a hollow slab 1 and multiple inner molds 101. The inner molds 101 are all installed on the hollow slab 1, and a steel mesh 102 is installed between the hollow slab 1 and the inner molds 101. The inner molds 101 are installed on the hollow slab 1 via the steel mesh 102. The hollow slab 1, the inner molds 101, and the steel mesh 102 constitute a hollow core slab.

[0031] Preferably, the hollow slab 1 is made of cast-in-place reinforced concrete, which not only ensures strength but also provides thermal conductivity.

[0032] like Figures 1 to 5 As shown, the exhaust fan 3 has a return pipe 301 connected to its outlet end, which is connected to the outlet end of the heat pump evaporator or condenser. The gas drawn in by the exhaust fan 3 can be transported to the outlet end of the evaporator or condenser through the return pipe 301 to allow the gas to return.

[0033] The return pipe 301 is equipped with a one-way valve, which makes it difficult for gas from the outlet of the evaporator or condenser to flow back into the exhaust fan 3 through the return pipe 301.

[0034] like Figures 1 to 2 As shown, the inner mold 101 is a thin-walled square box 1011. A connecting pipe 4 connects adjacent pairs of thin-walled square boxes 1011. Multiple thin-walled square boxes 1011 are connected in series through the connecting pipe 4 to form a gas flow channel. The cold air or hot air generated by the evaporator or condenser flows in the inner mold 101 of the hollow floor slab and radiates into the room through the hollow floor slab to achieve the effect of cooling or heating.

[0035] Among them, a heat-conducting plate 103 is provided between the thin-walled square box 1011 and the steel mesh 102, which can achieve better heat conduction effect.

[0036] In addition, the thin-walled square box 1011 is made of heat-insulating or heat-conducting material. When the thin-walled square box 1011 is made of heat-insulating material, it can conduct heat unidirectionally. When the thin-walled square box 1011 is made of heat-conducting material, it can conduct heat unidirectionally.

[0037] like Figures 3 to 5 As shown, the inner mold 101 is a hollow tube 1012, and a connecting pipe 4 connects adjacent pairs of hollow tubes 1012. Multiple hollow tubes 1012 are connected in series through multiple connecting pipes 4 to form a gas flow channel. The gas flow channel is used for cold air or hot air generated by the evaporator or condenser to circulate in the inner mold 101 of the hollow floor slab, and to radiate into the room through the hollow floor slab to achieve the effect of cooling or heating.

[0038] The hollow tube 1012 is secured with a metal clip 401, which connects it to the reinforcing mesh 102. The metal clip 401 not only secures the hollow tube 1012, but also allows the gas temperature inside the hollow tube 1012 and connecting pipe 4 to radiate into the room through the metal clip 401 and the hollow plate 1, achieving a cooling or heating effect.

[0039] In summary, this application connects the inner mold 101 and the connecting pipe 4 in series to form a gas flow channel, which is then connected to the exhaust fan 3 and the evaporator or condenser to form a closed airflow space. When the heat pump air conditioner 2 is running, it can generate either cold or hot air. Under the action of the exhaust fan 3, the cold or hot air can circulate within the gas flow channel and radiate into the room through the steel mesh 102 and hollow plate 1, achieving a cooling or heating effect. Since the gas is not directly discharged into the room, the air conditioning system of this application has advantages such as energy saving, no indoor wind, no noise, and comfortable use.

[0040] It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of this disclosure is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this disclosure. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0041] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
