Description

TECHNICAL FIELD

[0001] The present application relates to the air conditioning technical field, especially to a condenser and an air conditioning system. BACKGROUND

[0002] In the refrigeration cycle system of a water chiller, the high-temperature and high-pressure gaseous refrigerant discharged by the compressor enters the condenser inlet, and the refrigerant is in a superheated state. When the superheated gaseous refrigerant changes phase, there is a transition point temperature (related to the saturation temperature and the cold wall temperature, generally very close to the saturation temperature, hereinafter referred to as the saturation temperature). When the superheated gaseous refrigerant temperature is higher than the saturation temperature, the refrigerant vapor releases sensible heat, and the refrigerant temperature decreases without phase change. When the gaseous refrigerant reaches the saturation temperature, the refrigerant vapor releases latent heat and condenses, and the refrigerant temperature remains unchanged. Since the gaseous refrigerant entering the condenser has a certain degree of superheat, the heat exchange tubes near the top gas inlet in the condenser will inevitably have a superheated gaseous refrigerant cooling area that does not change phase. That is, after the superheated gaseous refrigerant enters the condenser, the superheated gaseous refrigerant is first cooled to gaseous saturated refrigerant at the heat exchange tubes near the condenser inlet; and then the gaseous saturated refrigerant is condensed into liquid refrigerant. It can be seen that in the existing condenser, the superheated gaseous refrigerant is cooled to gaseous saturated refrigerant, which requires a separate heat exchange area, resulting in high cost of the heat exchanger.

[0003] Although the heat (sensible heat) required to cool the superheated gaseous refrigerant to saturated gaseous refrigerant is much lower than the heat (latent heat) released when the saturated gaseous refrigerant is condensed into liquid refrigerant, the heat exchange coefficient of single-phase convective heat transfer (the heat exchange coefficient of superheated gaseous refrigerant cooling to saturated gaseous refrigerant) is much smaller than the heat exchange coefficient of condensation phase change (the heat exchange coefficient of saturated gaseous refrigerant condensing into liquid refrigerant). Therefore, the proportion of heat exchange area for exchanging sensible heat in the condenser cannot be ignored. Due to the low efficiency of single-phase convective heat transfer, the performance of the entire condenser is affected. On the other hand, according to the Nusselt film condensation model of heat transfer, the condensation thermal resistance is mainly dominated by the liquid conduction thermal resistance, so the thicker the liquid film, the worse the condensation effect.

[0031] Example 1

[0032] This embodiment describes the condenser of the present application in detail.

[0033] ​The condenser of the embodiment comprises a shell 10 and heat exchange pipes 20, the heat exchange pipes 20 are arranged in the shell 10, and air distribution devices 30 are arranged between the heat exchange pipes 20, the air distribution devices 30 are communicated with air inlets 101 on the shell 10, the surfaces of the air distribution devices 30 are provided with air distribution holes 301, and the superheated gaseous refrigerant entering from the air inlets 101 is sprayed out through the air distribution holes 301, as shown in Figures 1-3 The air distribution holes 301 are not limited to the form of holes, and can be in the form of slits. Preferably, the air distribution holes 301 are arranged on the upper and lower surfaces of the air distribution devices 30, as shown in Figure 2 and Figure 3 Preferably, the structure of the shell 10 is the same as that of the prior art, and specifically, the shell 10 is provided with the air inlets 101 and liquid outlets 102. The condenser of the embodiment is a horizontal shell and tube condenser (here, the horizontal preferably means that the heat exchange pipes 20 are in a horizontal state), as shown in Figure 1 It is known that the condenser can further comprise a water chamber 40 and a tube sheet 50, as shown in Figure 1 The structures and functions of the water chamber 40 and the tube sheet 50 can be the same as those of the prior art, and will not be described here.

[0034] Preferably, the air distribution devices 30 are arranged in the middle of the shell 10, so that the number of the heat exchange pipes 20 above and below the air distribution devices 30 is equivalent, as shown in Figure 1 and Figure 2 The air distribution devices 30 can also be arranged above the shell 10, so that the number of the heat exchange pipes 20 below the air distribution devices 30 is greater than that above the air distribution devices 30. The air distribution devices 30 can also be arranged below the shell 10, so that the number of the heat exchange pipes 20 above the air distribution devices 30 is greater than that below the air distribution devices 30.

[0035] The condenser of the embodiment comprises a shell 10 and heat exchange pipes 20, the heat exchange pipes 20 are arranged in the shell 10, and a gas distribution device 30 is arranged between the heat exchange pipes 20, the gas distribution device 30 is communicated with an air inlet 101 on the shell 10, the surface of the gas distribution device 30 is provided with gas distribution holes 301, so that the superheated gaseous refrigerant entering the condenser firstly enters the gas distribution device 30 through the air inlet 101, and then is sprayed into the heat exchange space through the gas distribution holes 301 on the gas distribution device 30, the superheated gaseous refrigerant sprayed into the heat exchange space can be in contact with the liquid refrigerant in the heat exchange space, the liquid refrigerant exchanges heat with the superheated gaseous refrigerant, so that the superheated gaseous refrigerant is cooled into gaseous saturated refrigerant, and part of the liquid refrigerant is vaporized into gaseous saturated refrigerant, the liquid refrigerant becomes gaseous saturated refrigerant together with the gaseous saturated refrigerant changed from the superheated gaseous refrigerant, and then flows to the surface of the heat exchange pipes 20, and is changed into liquid refrigerant after exchanging heat with the fluid in the heat exchange pipes 20, so that all the refrigerant exchanged with the fluid in the heat exchange pipes 20 is gaseous saturated refrigerant (without superheated gaseous refrigerant), so as to avoid the waste of heat exchange area caused by single-phase convection heat exchange. That is, the condenser of the embodiment can also be called a condenser capable of automatically cooling superheated steam.

[0036] It can be seen that, by arranging the gas distribution device 30 between the heat exchange pipes 20, the condenser of the embodiment can transfer the area where the superheated gaseous refrigerant is cooled into gaseous saturated refrigerant to the heat exchange space (the heat exchange space is also the area for condensing saturated gaseous refrigerant into liquid refrigerant in the prior art), so as to save the heat exchange area for cooling the superheated gaseous refrigerant into gaseous saturated refrigerant, and further reduce the number of heat exchange pipes 20 and the cost of the condenser. That is, the condenser of the embodiment solves the technical problem that the superheated gaseous refrigerant needs a separate heat exchange area to be cooled into gaseous saturated refrigerant, which causes high cost of the heat exchanger. On the other hand, the condenser of the embodiment can realize uniform gas distribution through the gas distribution device 30, so that the flow of the refrigerant is more uniform, the flow rate of the refrigerant gas in the shell is reduced, the pressure drop of the refrigerant gas in the condenser is reduced, the exhaust port pressure of the compressor is reduced, the system energy consumption is reduced, the saturation temperature of the refrigerant gas is also reduced, and the effective heat exchange temperature difference of the condenser is reduced.

[0037] According to a preferred embodiment, the gas distribution device 30 is further provided with a liquid flow channel 302, the liquid flow channel 302 is used for flowing of the condensing liquid, and the liquid flow channel 302 is communicated with a liquid outlet 102 on the shell 10, as shown in Figure 3The number of liquid flow channels 302 is preferably multiple, so that the liquid refrigerant dropping on the air distribution device 30 can flow out from different liquid flow channels 302. The liquid flow channels 302 are preferably not limited to rectangular, square, circular or other structures. The condenser of the preferred technical solution of the present embodiment is also provided with liquid flow channels 302 on the air distribution device 30, and the liquid refrigerant is guided to the liquid outlet 102 through the liquid flow channels 302, so as to reduce the thickness of the liquid film on the surface of the heat exchange tube 20, thereby enhancing the heat transfer efficiency of the heat exchange tube 20.

[0038] Specifically, as shown in Figure 1 and Figure 2 The condenser of the preferred technical solution of the present embodiment is used to condense the superheated gaseous refrigerant into liquid refrigerant and make the liquid refrigerant flow out from the liquid outlet 102 in the following way:

[0039] The gaseous refrigerant enters the air distribution device 30 from the air inlet 101, and then is sprayed from the air distribution holes 301 on the air distribution device 30 to the surface of the heat exchange tube 20 from the top and bottom. The cooling water flows in the heat exchange tube 20, and cools the gaseous refrigerant outside the heat exchange tube 20 and condenses it into liquid refrigerant. The liquid refrigerant on the surface of the heat exchange tube 20 on the upper part of the air distribution device 30 drops to the upper surface of the air distribution device 30 due to gravity, and fully contacts with the superheated gaseous refrigerant just sprayed from the upper surface of the air distribution device 30, so that the superheated gaseous refrigerant is cooled into gaseous saturated refrigerant, and part of the liquid refrigerant is vaporized into gaseous saturated refrigerant and flows to the surface of the heat exchange tube 20 on the upper part of the air distribution device 30 together with the gaseous saturated refrigerant. The remaining liquid refrigerant flows to the lower surface of the air distribution device 30 from the liquid flow channels 302, fully contacts with the superheated gaseous refrigerant sprayed from the lower surface of the air distribution device 30, so that the superheated gaseous refrigerant is cooled into gaseous saturated refrigerant, and part of the liquid refrigerant is vaporized into gaseous saturated refrigerant and flows to the surface of the heat exchange tube 20 on the lower part of the air distribution device 30 together with the gaseous saturated refrigerant. The gaseous saturated refrigerant exchanges heat with the cooling water in the heat exchange tube 20 and becomes liquid refrigerant. Finally, all the liquid refrigerant flows out from the liquid outlet 102. In this way, the gaseous refrigerant exchanged with the surface of the heat exchange tube 20 is kept in a saturated state, avoiding the waste of heat exchange area caused by single-phase convection heat transfer.

[0040] On the other hand, the condensation heat transfer coefficient h can be obtained from the Nusselt condensation model as follows: where δ l is the thickness of the liquid film. As can be seen, the thinner the liquid film, the higher the condensation heat transfer coefficient. Due to the presence of the air distribution device 30, at least part of the liquid refrigerant condensed by the heat exchange tube 20 on the upper part of the air distribution device 30 can be guided away through the liquid flow channels 302, so that the thickness of the liquid film on the surface of most of the heat exchange tubes 20 is greatly reduced. Due to the reduction of the thickness of the liquid film, the condensation heat transfer coefficient of the condenser is increased, and the heat transfer efficiency of the condenser is enhanced.

[0041] According to a preferred embodiment, the air distribution device 30 is parallel to the heat exchange tube 20, as shown in Figure 1 and Figure 2 . That is, the heat exchange tube 20 is in a horizontal state, and the corresponding air distribution device 30 is also in a horizontal state, as shown in Figure 1 and Figure 2 . The condenser of the preferred technical solution of the present embodiment can make the superheated gaseous refrigerant sprayed from the upper and lower surfaces of the air distribution device 30 fully contact with the liquid refrigerant, so that the superheated gaseous refrigerant can be completely cooled to gaseous saturated refrigerant.

[0042] According to a preferred embodiment, the air distribution device 30 comprises a first plate body 303 and a second plate body 304, the first plate body 303 and the second plate body 304 are arranged in a spaced manner, and an air flow channel 305 is formed between the first plate body 303 and the second plate body 304, the air flow channel 305 is in communication with the gas inlet 101, as shown in Figures 3-5 . Preferably, a plurality of air distribution holes 301 are uniformly arranged on the first plate body 303 and the second plate body 304, as shown in Figure 3 . Preferably, a plurality of liquid flow channels 302 are arranged on the first plate body 303 and the second plate body 304 respectively, the liquid flow channels 302 on the first plate body 303 and the liquid flow channels 302 on the second plate body 304 are in communication with each other, as shown in Figure 3 . The condenser of the preferred technical solution of the present embodiment can make the superheated gaseous refrigerant entering through the gas inlet 101 enter the air flow channel 305, and then be sprayed into the heat exchange space through the air distribution holes 301, compared with the structure that the refrigerant directly enters the heat exchange space in the prior art, the condenser of the preferred technical solution of the present embodiment can realize uniform air distribution, make the flow of the refrigerant more uniform, reduce the flow rate of the refrigerant gas in the shell, thereby reducing the pressure drop of the refrigerant gas in the condenser, and further reducing the discharge port pressure of the compressor, reducing the system energy consumption, and also reducing the saturation temperature of the refrigerant gas, reducing the effective heat exchange temperature difference of the condenser.

[0043] According to a preferred embodiment, the first plate body 303 and the second plate body 304 have horizontal sections and inclined sections, the horizontal sections of the first plate body 303 and the second plate body 304 form the air flow channel 305, the inclined section of the first plate body 303 and the inclined section of the second plate body 304 form a gas inlet, and the opening diameter of the end of the gas inlet in communication with the gas inlet 101 is greater than the opening diameter of the end of the gas inlet in communication with the air flow channel 305, as shown in Figures 2-5The opening diameter of the one end of the gas inlet communicated with the gas inlet 101 is greater than the opening diameter of the one end of the gas inlet communicated with the gas flow channel 305, which can ensure that the overheated gaseous refrigerant in the gas flow channel 305 has sufficient speed to be sprayed out of the gas distribution hole 301.

[0044] According to a preferred embodiment, the inclined sections of the first plate body 303 and the second plate body 304 are oppositely inclined; or the inclined sections of the first plate body 303 and the second plate body 304 are both inclined downward; or the inclined sections of the first plate body 303 and the second plate body 304 are both inclined upward, as shown in Figure 4 or Figure 5 Preferably, a liquid blocking plate 306 is arranged at the gas inlet, one end of the liquid blocking plate 306 is fixed to the inclined section of the second plate body 304, and the other end of the liquid blocking plate 306 is higher than the horizontal section of the second plate body 304, as shown in Figure 4 Preferably, the condenser of the preferred technical solution of the present embodiment is provided with the liquid blocking plate 306 at the gas inlet, and the liquid blocking plate 306 can prevent the backflow of the liquid refrigerant in the stoppage or other special working conditions, i.e., prevent the liquid refrigerant from flowing back from the liquid flow channel 302 of the gas distribution device 30 to the gas inlet 101.

[0045] When the inclined sections of the first plate body 303 and the second plate body 304 are both inclined upward, the liquid blocking plate 306 can not be arranged, and the length of the horizontal section of the second plate body 304 is longer than the length of the horizontal section of the first plate body 303, as shown in Figure 5 Preferably, the condenser of the preferred technical solution of the present embodiment is provided with the liquid blocking plate 306 at the gas inlet, and the liquid blocking plate 306 can prevent the backflow of the liquid refrigerant in the stoppage or other special working conditions, i.e., prevent the liquid refrigerant from flowing back from the liquid flow channel 302 of the gas distribution device 30 to the gas inlet 101.
