Description

Compressor is the core component of air conditioning refrigeration system, which plays the role of heart and provides necessary power for the whole system. Through its work, refrigerant can circulate in the system, so as to realize the effect of refrigeration or heating. Compressor inhales low-temperature and low-pressure refrigerant vapor from evaporator, which becomes low-temperature and low-pressure after absorbing heat in evaporator. Compressor compresses these vapors through its internal mechanical structure, so that their temperature and pressure are improved. After compression, refrigerant vapor becomes high-temperature and high-pressure superheated vapor. This change is the key step in refrigeration cycle, which provides necessary conditions for subsequent condensation and throttling process.

[0066] During the process of refrigeration or heating, if the compressor is overloaded due to long-time operation, excessive load or system failure, etc., the current control strategy often directly switches the speed of the compressor to attempt to restore its normal operating state or reduce the overload pressure. However, this direct switching of the speed, although it can quickly respond to the overload condition of the compressor, also brings a significant problem: the temperature in the passenger cabin will change significantly.

[0067] Specifically, the adjustment of the speed of the compressor directly affects its refrigeration or heating capacity. When the speed is increased, the refrigeration or heating efficiency increases, and the temperature in the passenger cabin will rapidly decrease or increase; conversely, when the speed is reduced, the refrigeration or heating efficiency is weakened, and the temperature in the passenger cabin will tend to rise or decrease. This fluctuation in refrigeration / heating capacity due to sudden changes in the speed of the compressor will cause the temperature in the passenger cabin to experience a large fluctuation in a short period of time, giving passengers an uncomfortable feeling.

[0068] To this end, the utility model provides a kind of air conditioning system, this air conditioning system includes air circulation loop and heat transfer medium circulation loop, air circulation loop and heat transfer medium circulation loop between heat exchange is carried out by heat exchange component, and, air circulation loop is provided with the energy storage component and air outlet structure of series connection on it, the one end of energy storage component and the air outlet structure intercommunication pipeline constitute supplementary branch, the other end and the air outlet structure intercommunication pipeline constitute heat exchange branch.When heat exchange branch and heat transfer medium circulation loop carry out heat exchange, can store part of heat in energy storage component, when the compressor rotation speed in heat transfer medium circulation loop is sudden change, thereby leading to the temperature change of air in air circulation loop, can be supplemented by the heat in energy storage component, at this time, energy storage component in energy release state will air be transported to air outlet structure by supplementary branch, air temperature that can be supplemented by heat exchange branch to air outlet structure, ensure that the air temperature change of air outlet structure blowing is smaller.

[0069] To make the purpose, technical scheme and advantage of the utility model more clear, the implementation of the utility model will be further described in detail below with the drawings.

[0070] As Figure 1 And Figure 2 The embodiment of the utility model discloses an air conditioning system 10, this air conditioning system 10 includes air circulation loop 100 and heat transfer medium circulation loop 200, air circulation loop 100 is provided with the energy storage component 110 and air outlet structure 120 of series connection on it, energy storage component 110 can switch in energy storage state and energy release state.

[0071] Wherein, the one end of energy storage component 110 and the air outlet structure 120 intercommunication pipeline constitute supplementary branch 130, the other end and the air outlet structure 120 intercommunication pipeline constitute heat exchange branch 140, heat exchange branch 140 and heat transfer medium circulation loop 200 between being provided with heat exchange component 300.

[0072] And, on heat exchange branch 140, air that is exchanged with heat transfer medium circulation loop 200 after heat exchange component 300 is part of flow to air outlet structure 120, another part flows to energy storage component 110 in energy storage state, on supplementary branch 130, air from energy storage component 110 in energy release state flows to air outlet structure 120.It needs to be explained that, to ensure that air that is exchanged with heat transfer medium circulation loop 200 after heat exchange component 300 is part of flow to air outlet structure 120, on heat exchange branch 140, between heat exchange component 300 and air outlet structure 120, be provided with air blower 141, regarding the specific structure of air blower 141, the utility model does not make specific limitation to this.

[0073] The air conditioning system 10 is provided with a heat exchange component 300 between the heat exchange branch 140 and the heat transfer medium circulation loop 200, so as to realize heat exchange between the heat exchange branch 140 and the heat transfer medium circulation loop 200, so that the air outlet structure 120 on the air circulation loop 100 can output air with different temperatures to the outside. In addition, the air circulation loop 100 is also provided with an energy storage component 110, when the heat exchange branch 140 and the heat transfer medium circulation loop 200 exchange heat, a part of the heat can be stored in the energy storage component 110, when the compressor 211 in the heat transfer medium circulation loop 200 suddenly changes the speed, so that the temperature of the air in the air circulation loop 100 changes, the heat in the energy storage component 110 can be supplemented, at this time, the energy storage component 110 in the energy release state delivers air to the air outlet structure 120 through the supplement branch 130, which can supplement the temperature of the air flowing to the air outlet structure 120 through the heat exchange branch 140, and ensure that the temperature change of the air blown by the air outlet structure 120 is small.

[0074] In addition, as shown in Figure 2 , in order to facilitate the control of the energy storage component 110 switching between the energy storage state and the energy release state, an energy storage valve 101 is arranged at the upstream position of the energy storage component 110, and an energy release valve 102 is arranged at the downstream position of the energy storage component 110. Specifically, when the energy storage component 110 stores energy, the energy storage valve 101 is opened, so that a part of the air exchanged with the heat exchange component 300 can flow to the energy storage component 110; when the energy storage component 110 releases energy, the energy release valve 102 is opened, so that the energy storage component 110 can send air to the air outlet structure 120 through the supplement branch 130. The specific structure of the valve can be designed by those skilled in the art according to the actual situation and specific needs, and the embodiment does not make specific limitation.

[0075] Further, in order for the energy storage component 110 to store energy efficiently and supplement the air temperature of the air outlet structure 120, as shown in Figure 3 , the air circulation loop 100 is provided with a heat storage branch 150 and a cold storage branch 160 in parallel with each other at a position between the heat exchange branch 140 and the supplement branch 130.

[0076] As shown in Figure 3 and Figure 4 , the heat storage branch 150 is provided with a heat storage component 111, a first valve 151 is arranged at the upstream position of the heat storage component 111, and a second valve 152 is arranged at the downstream position of the heat storage component 111.

[0077] As shown in Figure 3 and Figure 4As shown, the cold storage branch 160 is provided with a cold storage component 112, and the third valve 161 is arranged at the upstream position of the cold storage component 112, and the fourth valve 162 is arranged at the downstream position of the cold storage component 112.

[0078] Specifically, the air circulation loop 100 is provided with a heat storage branch 150 and a cold storage branch 160, wherein the heat storage component 111 on the heat storage branch 150 can store heat, when the air conditioning system 10 needs to heat through the air outlet structure 120, the second valve 152 is opened, and the heat storage component 111 can transmit hot air to the air outlet structure 120 through the supplement branch 130 to improve the temperature of the air blown out by the air outlet structure 120; the cold storage component 112 on the cold storage branch 160 can store cold, when the air conditioning system 10 needs to cool through the air outlet structure 120, the fourth valve 162 is opened, and the cold storage component 112 can transmit cold air to the air outlet structure 120 through the supplement branch 130 to reduce the temperature of the air blown out by the air outlet structure 120, thereby improving the heating and cooling effects of the air conditioning system 10 respectively.

[0079] Of course, when the heat storage component 111 needs to store heat, the first valve 151 is opened, so that the hot air in the heat exchange component 300 that absorbs the heat of the heat transfer medium circulation loop 200 flows to the heat storage component 111 through the heat exchange branch 140, and when the cold storage component 112 needs to store cold, the third valve 161 is opened, so that the cold air in the heat exchange component 300 that absorbs the cold of the heat transfer medium circulation loop 200 flows to the cold storage component 112 through the heat exchange branch 140.

[0080] It should be noted that in order to affect each other between the heat storage component 111 and the cold storage component 112, when any valve on one branch is opened, the valves on the other branch are closed. For example, when the heat storage component 111 stores heat, the first valve 151 at the upstream position of the heat storage component 111 is opened, and the second valve 152 at the downstream position of the heat storage component 111 can be opened or closed. If the second valve 152 is opened, the heat storage component 111 simultaneously transmits hot air to the air outlet structure 120 through the supplement branch 130, and the third valve 161 and the fourth valve 162 on the cold storage branch 160 are closed. When the cold storage component 112 stores cold, it is similar and will not be described here.

[0081] Further, as shown in the figure, Figure 3 On the heat exchange branch 140, a first bypass branch 170 connected to the supplement branch 130 is arranged at the position between the heat exchange component 300 and the energy storage component 110. When the energy storage component 110 does not need to store energy, the air exchanged with the heat transfer medium circulation loop 200 through the heat exchange component 300 bypasses the energy storage component 110 and directly flows through the first bypass branch.

[0082] Further, as shown in Figure 4 The second bypass branch 180 is connected to the supplementary branch 130 at a position between the heat exchange component 300 and the air outlet structure 120 in the heat exchange branch 140.

[0083] Further, the fifth valve 142 is arranged at a position downstream of the second bypass branch 180 in the heat exchange branch 140, and the sixth valve 181 is arranged at the second bypass branch 180.

[0084] When there is no need for refrigeration or heating from the outside, the fifth valve 142 is closed, and the sixth valve 181 is opened. The bypass branch arranged between the heat exchange component 300 and the air outlet structure 120 allows the heat exchange branch 140 to exchange heat with the heat transfer medium circulation loop 200, and the air from the bypass branch bypasses the air outlet structure 120, so that only heat or cold is stored in the energy storage component 110.

[0085] The specific structure of the air circulation loop 100 is not limited to the structure in the above embodiment, and can be designed according to actual conditions and specific needs by those skilled in the art, and the present embodiment does not make specific limitations.

[0086] The specific structure of the energy storage component 110 will be described below.

[0087] As the name implies, the energy storage component 110 is a component for storing energy. In one embodiment, as shown in Figure 5 The energy storage component 110 has a cavity for storing air. The air carrying heat or cold is directly stored in the cavity, and when the energy storage component 110 supplies air to the air outlet structure 120 through the supplementary branch 130, the air carrying heat or cold in the cavity is directly output from the supplementary branch 130. Of course, in order to prevent the air carrying heat or cold in the cavity from being affected by the external environment, a shell with heat preservation function can be arranged outside the energy storage component 110.

[0088] Further, as shown in Figure 6 and Figure 7 In order to better store energy, the energy storage component 110 can also be arranged as follows:

[0089] The energy storage component 110 has an air passage 103 connected to the heat exchange branch 140 and the supplementary branch 130, and a phase change energy storage material 104 is arranged around the periphery of the air passage 103; and a heat preservation layer 105 is formed outside the energy storage component 110.

[0090] The air in the heat exchange branch 140 flows into the energy storage component 110 through the air channel 103, and since the phase change energy storage substance 104 is arranged around the periphery of the air channel 103, the heat or cold can be better stored, and the heat insulation layer 105 arranged outside the energy storage component 110 can prevent the heat or cold from leaking out, thereby improving the energy storage performance of the energy storage component 110. It should be noted that the phase change energy storage substance 104 can be a substance with a large heat capacity such as a salt water mixture or paraffin, and a person skilled in the art can make a selection according to the actual situation and specific requirements, and the present embodiment does not make a specific limitation in this regard.

[0091] Further, the air channel 103 inside the energy storage component 110 extends in a spiral shape, which can prolong the residence time of the air in the air channel 103, thereby facilitating the energy storage of the phase change energy storage substance 104 around the periphery of the air channel 103.

[0092] Further, a plurality of heat transfer ribs can be arranged on the inner wall surface of the air channel 103, thereby increasing the energy storage efficiency of the phase change energy storage substance 104.

[0093] It should be noted that the heat storage component 111 and the cold storage component 112 are energy storage components 110, and as shown in Figure 6 and Figure 7 , both adopt the above structure, and the only difference is that the heat storage component 111 is used for storing heat, and the cold storage component 112 is used for storing cold.

[0094] The specific structure of the energy storage component 110 will be described below.

[0095] As shown in Figures 2-4 , the heat transfer medium circulation loop 200 includes a main trunk 210, a refrigeration branch 220 connected in series with the main trunk 210, and a heating branch 230. It should be noted that the main trunk 210 refers to a pipeline through which the heat transfer medium always flows in both the refrigeration process and the heating process, while the refrigeration branch 220 refers to a pipeline through which the heat transfer medium flows only in the refrigeration process, and the heating branch 230 refers to a pipeline through which the heat transfer medium flows only in the heating process.

[0096] The main trunk 210 is provided with a compressor 211, the heating branch 230 is provided with an internal cooler 310, and the refrigeration branch 220 is provided with an evaporator 320, and the internal cooler 310 and the evaporator 320 constitute a heat exchange component 300.

[0097] The heat transfer medium in the heating branch 230 flows through the internal cooler 310 and exchanges heat with the air in the heat exchange branch 140, and the heat transfer medium in the refrigeration branch 220 flows through the evaporator 320 and exchanges heat with the air in the heat exchange branch 140.

[0105] In summary, the utility model discloses a kind of air conditioning systems 10, the refrigeration and heating working process of air conditioning system 10 are described below.

[0106] Refrigeration process:

[0107] The refrigerant from the compressor 211 flows along the main trunk 210 to the first three-way valve 240, and from the first three-way valve 240 to the refrigeration branch 220, and from the refrigeration branch 220 to the second three-way valve 250, and from the second three-way valve 250 to the external heat exchanger 212, and the refrigerant flowing out of the external heat exchanger 212 flows from the third three-way valve 260 to the refrigeration branch 220, and thus flows through the first expansion valve 221 and the evaporator 320 on the refrigeration branch 220, and transmits cold energy to the air in the air circulation loop 100 through the evaporator 320, that is, absorbs heat in the air circulation loop 100, and the refrigerant after absorbing heat flows along the refrigeration branch 220 to the fourth three-way valve 270, and flows back to the compressor 211 in the main trunk 210 from the fourth three-way valve 270.

[0108] In the air circulation loop 100, the cold air that is heated by the evaporator 320 flows along the heat exchange branch 140 to the air outlet structure 120 under the action of the air blower 141. When the cold storage component 112 needs to store cold, the third valve 161 and the fourth valve 162 are opened, and the cold air that is heated also passes through the cold storage component 112. Taking 3°C as an example, if the temperature of the air is lower than 3°C, the first valve 151 and the second valve 152 can be closed, and if the temperature of the air is higher than 3°C, the first valve 151 and the second valve 152 are closed when the operation is stable, so that the cold air is retained in the cold storage component 112. When the air conditioning system 10 starts, the compressor 211 has a high speed but a low refrigeration efficiency, the third valve 161 and the fourth valve 162 are opened, the cold air stored in the cold storage component 112 is transmitted to the air outlet structure 120 along the supplementary branch 130, and the cold air is used to assist refrigeration; and when the speed of the compressor 211 suddenly decreases, the temperature of the air in the air outlet structure 120 also suddenly increases, and the cold storage component 112 can also transmit the cold air stored therein to the air outlet structure 120 along the supplementary branch 130, so as to alleviate the sudden increase of the air outlet temperature.

[0109] Heating process:

[0110] The refrigerant from the compressor 211 flows along the main trunk 210 to the first three-way valve 240, and from the first three-way valve 240 to the heating branch 230, and then releases heat to the air circulation loop 100 through the internal cooler 310, and the refrigerant flowing out of the internal cooler 310 passes through the second expansion valve 231, and from the second three-way valve 250 to the external heat exchanger 212, and the refrigerant flowing out of the external heat exchanger 212 flows from the third three-way valve 260 to the heating branch 230, and then flows back to the compressor 211 in the main trunk 210 from the fourth three-way valve 270.

[0111] In the air circulation loop 100, the air heated by the internal cooler 310 flows to the air outlet structure 120 along the heat exchange branch 140 under the action of the air blower 141. When the heat storage component 111 needs to store heat, the first valve 151 and the second valve 152 are opened, and the heated air also passes through the heat storage component 111. Taking the target temperature of 40℃ as an example, if the temperature of the air is higher than 40℃, the first valve 151 and the second valve 152 can be closed, and if the temperature of the air is lower than 40℃, the first valve 151 and the second valve 152 are closed when the operation is stable, so that the hot air is retained in the heat storage component 111. When the air conditioning system 10 starts, the compressor 211 has a large rotating speed, but the heating efficiency is low, the first valve 151 and the second valve 152 are opened, the hot air stored in the heat storage component 111 is transmitted to the air outlet structure 120 along the supplement branch 130, and the heating is assisted. When the rotating speed of the compressor 211 suddenly decreases, the temperature of the air of the air outlet structure 120 also suddenly decreases, and the heat storage component 111 can also transmit the stored hot air to the air outlet structure 120 along the supplement branch 130, so that the sudden decrease of the air outlet temperature is alleviated.

[0112] The embodiment of the utility model discloses a kind of cars, and this car includes the air conditioning system 10 of any one described above, when the air conditioning system 10 heats or refrigerates the passenger compartment of car, if the rotating speed of compressor 211 in heat transfer medium circulation loop 200 suddenly changes, so that the temperature of air in air circulation loop 100 changes, the temperature change range in passenger compartment can be supplemented by the heat in energy storage component 110, to reduce, so as to provide comfortable riding environment for passenger in passenger compartment.

[0113] Further, as shown in Figure 8 The vehicle refrigerator 20 of the car is integrated on the cold storage component 112, and the cold storage component 112 stores cold energy to achieve refrigeration effect on the vehicle refrigerator 20.

[0114] Specifically, as shown in Figure 8 The cover plate of the vehicle refrigerator 20 is arranged outside to facilitate taking.

[0115] Of course, other components of the car that have cooling requirements can also be integrated on the cold storage component 112, and similarly, components that have heating requirements can be integrated on the heat storage component 111, and the utility model does not make specific limitation on this.
